mars curiosity rover on mars so uh 43 00:05:39,430 --> 00:05:37,199 celebrating lots of anniversaries but we 44 00:05:41,430 --> 00:05:39,440 do more than mars rovers we do 45 00:05:44,070 --> 00:05:41,440 astrophysics missions we study our home 46 00:05:45,749 --> 00:05:44,080 planet of earth and this is a great 47 00:05:48,469 --> 00:05:45,759 example of driving the frontiers of 48 00:05:50,469 --> 00:05:48,479 science from space fundamental physics 49 00:05:53,510 --> 00:05:50,479 basic knowledge about 50 00:05:56,070 --> 00:05:53,520 the behavior of matter and energy and 51 00:05:57,670 --> 00:05:56,080 gravity really understanding the truth 52 00:05:59,510 --> 00:05:57,680 and when they say fundamental physics it 53 00:06:01,830 --> 00:05:59,520 doesn't get more fundamental than the 54 00:06:03,909 --> 00:06:01,840 kind of work that we're doing with this 55 00:06:05,430 --> 00:06:03,919 cutting edge laboratory flying on the 56 00:06:08,070 --> 00:06:05,440 space station that 57 00:06:10,790 --> 00:06:08,080 zero g environment gives us a whole new 58 00:06:12,629 --> 00:06:10,800 way of exploring fundamental physics 59 00:06:14,790 --> 00:06:12,639

--> 00:09:44,959 scientific discovery and enabling human 156 00:09:48,710 --> 00:09:46,959 space flight exploration he is the 157 00:09:50,550 --> 00:09:48,720 biological and physical sciences 158 00:09:52,630 --> 00:09:50,560 division director and the science 159 00:09:59,670 --> 00:09:52,640 mission directorate at nasa headquarters 160 00:10:02,710 --> 00:10:01,030 thank you brian it's a great pleasure to 161 00:10:05,110 --> 00:10:02,720 be here to celebrate four years of the 162 00:10:06,790 --> 00:10:05,120 cold adam laboratory 163 00:10:08,069 --> 00:10:06,800 as brian just mentioned in the 164 00:10:09,590 --> 00:10:08,079 biological and physical sciences 165 00:10:11,750 --> 00:10:09,600 division we have a two-pronged mission 166 00:10:14,230 --> 00:10:11,760 of pioneering scientific discovery and 167 00:10:16,949 --> 00:10:14,240 enabling sustainable exploration 168 00:10:19,670 --> 00:10:16,959 cal is the exemplar of pioneering 169 00:10:21,110 --> 00:10:19,680 scientific discovery in bps biological 170 00:10:24,150 --> 00:10:21,120 and physical sciences 171 00:10:25,269 --> 00:10:24,160 um unlike our uh scientific brethren in 172 00:10:26,389 --> 00:10:25,279 the rest of the science mission 173 00:10:29,910 --> 00:10:26,399 directorate 174 00:10:32,790 --> 00:10:29,920 which typically study space or from or 175 00:10:34,470 --> 00:10:32,800 the earth from space at very large 176 00:10:36,790 --> 00:10:34,480 scales typically 177 00:10:38,790 --> 00:10:36,800 in bps we are experimentalists and cal 178 00:10:41,430 --> 00:10:38,800 is a great example of an experimental 179 00:10:43,590 --> 00:10:41,440 program that is capitalizing on the 180 00:10:46,470 --> 00:10:43,600 unique environment in low earth orbit on 181 00:10:49,110 --> 00:10:46,480 the iss which is basically long duration 182 00:10:51,430 --> 00:10:49,120 free fall where atoms can be studied at 183 00:10:53,509 --> 00:10:51,440 ultra cold temperatures in extremely 184 00:10:55,750 --> 00:10:53,519 weak potentials and you'll hear a lot 185 00:10:58,069 --> 00:10:55,760 more about that in the subsequent talks 186 00:11:00,630 --> 00:10:58,079 but at a top level cal has already had 187 00:11:01,910 --> 00:11:00,640 many firsts 188 00:11:05,110 --> 00:11:01,920 recently 189 00:11:07,110 --> 00:11:05,120 the cal project published on quantum 190 00:11:10,630 --> 00:11:07,120 bubbles you'll hear a bit more about 191 00:11:13,829 --> 00:11:10,640 this later and just last week at the iss 192 00:11:15,910 --> 00:11:13,839 research and development conference 193 00:11:18,150 --> 00:11:15,920 nathan lunblatt representing the bubble 194 00:11:20,630 --> 00:11:18,160 team and the jpl ops team accepted an 195 00:11:23,110 --> 00:11:20,640 award for the physical science uh result 196 00:11:24,630 --> 00:11:23,120 of the year award at that conference 197 00:11:26,389 --> 00:11:24,640 very noteworthy 198 00:11:28,790 --> 00:11:26,399 cal has created the first boze einstein 199 00:11:31,590 --> 00:11:28,800 condensates in space 200 00:11:32,710 --> 00:11:31,600 and has created the coldest place in 201 00:11:35,190 --> 00:11:32,720 space 202 00:11:37,590 --> 00:11:35,200 and so cal as you'll hear more about 203 00:11:41,110 --> 00:11:37,600 later has pioneered in many respects 204 00:11:42,949 --> 00:11:41,120 but with pioneering very often it comes 205 00:11:45,590 --> 00:11:42,959 difficulty and i want to give a shout 206 00:11:47,190 --> 00:11:45,600 out to the broad number of people that 207 00:11:50,310 --> 00:11:47,200 have been involved in making callus 208 00:11:53,110 --> 00:11:50,320 success starting with here at jpl the 209 00:11:54,949 --> 00:11:53,120 hardware developers and operations team 210 00:11:56,710 --> 00:11:54,959 the science team 211 00:11:58,790 --> 00:11:56,720 the principal investigators and their 212 00:12:01,110 --> 00:11:58,800 teams coming together to solve 213 00:12:03,430 --> 00:12:01,120 many challenges in operating cal 214 00:12:05,670 --> 00:12:03,440 the iss program in 215 00:12:07,269 --> 00:12:05,680 in supporting operations 216 00:12:11,670 --> 00:12:07,279 and 217 00:12:13,590 --> 00:12:11,680 course as you'll hear later 218 00:12:15,430 --> 00:12:13,600 are astronauts and one in particular 219 00:12:16,230 --> 00:12:15,440 you'll hear from today 220 00:12:18,069 --> 00:12:16,240 so 221 00:12:21,269 --> 00:12:18,079 pioneering isn't easy and this group has 222 00:12:22,790 --> 00:12:21,279 done a fantastic job to be tenacious 223 00:12:24,870 --> 00:12:22,800 patient 224 00:12:27,030 --> 00:12:24,880 and show that fortitude to to bring all 225 00:12:28,150 --> 00:12:27,040 these results having said that we know 226 00:12:29,910 --> 00:12:28,160 that there's some really exciting 227 00:12:31,030 --> 00:12:29,920 results uh in future because just 228 00:12:34,069 --> 00:12:31,040 recently 229 00:12:36,069 --> 00:12:34,079 uh cal has demonstrated dual species 230 00:12:38,150 --> 00:12:36,079 bose einstein condensates uh you learn 231 00:12:40,150 --> 00:12:38,160 about that and demonstrated atom 232 00:12:41,430 --> 00:12:40,160 interferometry so you'll hear about 233 00:12:42,550 --> 00:12:41,440 these things which are opening up a 234 00:12:44,870 --> 00:12:42,560 whole new 235 00:12:45,670 --> 00:12:44,880 lane of research for the coming years 236 00:12:47,670 --> 00:12:45,680 and 237 00:12:49,990 --> 00:12:47,680 with that i'd like to again 238 00:12:51,430 --> 00:12:50,000 emphasize my thanks to the broad cal 239 00:12:52,550 --> 00:12:51,440 team uh 240 00:12:54,629 --> 00:12:52,560 on their 241 00:12:55,829 --> 00:12:54,639 perseverance and dedication and to the 242 00:13:01,670 --> 00:12:55,839 great successes that we're able to 243 00:13:13,430 --> 00:13:05,150 and now let's hear more from john kalas 244 00:13:17,350 --> 00:13:15,590 good morning as mentioned i'm john kalas 245 00:13:19,670 --> 00:13:17,360 i'm the program manager for fundamental 246 00:13:21,190 --> 00:13:19,680 physics here at jpl 247 00:13:23,750 --> 00:13:21,200 let me also 248 00:13:25,590 --> 00:13:23,760 add my welcome to the cal science team 249 00:13:27,990 --> 00:13:25,600 and to all our distinguished guests here 250 00:13:30,710 --> 00:13:28,000 today and also let me 251 00:13:33,990 --> 00:13:30,720 also acknowledge the great technological 252 00:13:35,670 --> 00:13:34,000 and scientific accomplishment of the cal 253 00:13:37,829 --> 00:13:35,680 experiment 254 00:13:40,949 --> 00:13:37,839 so i'd like to give a little um 255 00:13:42,550 --> 00:13:40,959 scientific context to today's 256 00:13:45,030 --> 00:13:42,560 celebration 257 00:13:47,590 --> 00:13:45,040 so let me start here this is one of the 258 00:13:50,069 --> 00:13:47,600 recently released images from the james 259 00:13:51,189 --> 00:13:50,079 webb space telescope this is their 260 00:13:54,310 --> 00:13:51,199 first 261 00:13:56,470 --> 00:13:54,320 deep field survey and what you can see 262 00:14:00,870 --> 00:13:56,480 in this image which is no more than a 263 00:14:02,389 --> 00:14:00,880 grain of sand held at arm's length are 264 00:14:07,350 --> 00:14:02,399 thousands of galaxies 265 00:14:09,350 --> 00:14:07,360 a few stars and the effects of gravity 266 00:14:11,269 --> 00:14:09,360 these galaxies 267 00:14:13,750 --> 00:14:11,279 if they are like our own milky way 268 00:14:16,389 --> 00:14:13,760 galaxy consists of 269 00:14:18,550 --> 00:14:16,399 hundreds of billions of stars 270 00:14:22,389 --> 00:14:18,560 and so by extrapolation of that grain of 271 00:14:24,230 --> 00:14:22,399 sand to the entirety of the sky 272 00:14:27,910 --> 00:14:24,240 we can estimate that there's something 273 00:14:30,230 --> 00:14:27,920 of the order of 10 to the 22 274 00:14:32,389 --> 00:14:30,240 stellar systems out there in the 275 00:14:36,150 --> 00:14:32,399 observable universe this is an 276 00:14:38,470 --> 00:14:36,160 incredible domain of exploration 277 00:14:40,949 --> 00:14:38,480 and this observable universe is 278 00:14:43,430 --> 00:14:40,959 beautifully described by two great 279 00:14:45,350 --> 00:14:43,440 theories of fundamental physics the 280 00:14:48,150 --> 00:14:45,360 general theory of relativity which tells 281 00:14:49,910 --> 00:14:48,160 us about gravity and the standard model 282 00:14:52,150 --> 00:14:49,920 of particle physics which is essentially 283 00:14:53,030 --> 00:14:52,160 quantum mechanics or quantum field 284 00:14:55,269 --> 00:14:53,040 theory 285 00:14:58,629 --> 00:14:55,279 but as magnificent as these theories are 286 00:15:01,910 --> 00:14:58,639 and explaining what we see here we are 287 00:15:03,189 --> 00:15:01,920 only seeing a tiny fraction of our 288 00:15:04,790 --> 00:15:03,199 universe 289 00:15:07,590 --> 00:15:04,800 that's because 290 00:15:08,870 --> 00:15:07,600 more than 95 percent of our universe is 291 00:15:12,710 --> 00:15:08,880 dark 292 00:15:15,430 --> 00:15:12,720 that only a tiny fraction is luminous 293 00:15:18,470 --> 00:15:15,440 so this darkness is in two forms what we 294 00:15:20,790 --> 00:15:18,480 call dark energy and dark matter but we 295 00:15:23,030 --> 00:15:20,800 don't know what these are 296 00:15:24,710 --> 00:15:23,040 our standard model that i was just 297 00:15:26,470 --> 00:15:24,720 mentioning which beautifully describes 298 00:15:29,749 --> 00:15:26,480 the observable universe 299 00:15:32,710 --> 00:15:29,759 doesn't explain this this is a gaping 300 00:15:35,509 --> 00:15:32,720 hole in our understanding 301 00:15:37,110 --> 00:15:35,519 and further our very existence is 302 00:15:39,509 --> 00:15:37,120 incompatible 303 00:15:42,069 --> 00:15:39,519 with the standard model because the 304 00:15:45,030 --> 00:15:42,079 universe is made up of only what we call 305 00:15:46,550 --> 00:15:45,040 baryonic matter and no antimatter the 306 00:15:47,590 --> 00:15:46,560 standard model 307 00:15:48,949 --> 00:15:47,600 would 308 00:15:51,189 --> 00:15:48,959 explain that we should have equal 309 00:15:53,509 --> 00:15:51,199 amounts of each 310 00:15:55,189 --> 00:15:53,519 and so why is this 311 00:15:57,269 --> 00:15:55,199 and and further 312 00:15:59,829 --> 00:15:57,279 general relativity or theory of gravity 313 00:16:02,230 --> 00:15:59,839 is it really the last word on things why 314 00:16:03,829 --> 00:16:02,240 have we been unable to unify gravity 315 00:16:05,829 --> 00:16:03,839 with the other forces of nature with 316 00:16:07,910 --> 00:16:05,839 this standard model so these are 317 00:16:11,110 --> 00:16:07,920 significant shortcomings in our 318 00:16:13,509 --> 00:16:11,120 understanding of this vast universe and 319 00:16:14,550 --> 00:16:13,519 again we only observe a tiny fraction of 320 00:16:16,949 --> 00:16:14,560 it 321 00:16:18,710 --> 00:16:16,959 so our our great 322 00:16:21,030 --> 00:16:18,720 uh scientific 323 00:16:22,870 --> 00:16:21,040 vehicles exploration are giant 324 00:16:25,030 --> 00:16:22,880 accelerators on the ground our 325 00:16:28,470 --> 00:16:25,040 magnificent observatories have been 326 00:16:32,710 --> 00:16:28,480 unable to shed light on many of these 327 00:16:36,230 --> 00:16:32,720 great uh questions so how can we answer 328 00:16:38,550 --> 00:16:36,240 these questions well perhaps one way is 329 00:16:41,670 --> 00:16:38,560 to go into space 330 00:16:44,629 --> 00:16:41,680 the microgravity environment of space 331 00:16:47,110 --> 00:16:44,639 creates an opportunity for us to create 332 00:16:48,550 --> 00:16:47,120 perhaps the most precise sensors 333 00:16:51,509 --> 00:16:48,560 possible 334 00:16:54,870 --> 00:16:51,519 cold atoms free from the effects of 335 00:16:58,870 --> 00:16:54,880 gravity become these ultra precise 336 00:17:01,110 --> 00:16:58,880 quiescent tiny probes that we can use uh 337 00:17:02,230 --> 00:17:01,120 to explore these great scientific 338 00:17:04,390 --> 00:17:02,240 questions 339 00:17:06,630 --> 00:17:04,400 so okay specifically how would we go 340 00:17:08,069 --> 00:17:06,640 about investigating these questions well 341 00:17:10,710 --> 00:17:08,079 what we are trying to do in the 342 00:17:14,150 --> 00:17:10,720 fundamental physics program is use a 343 00:17:17,669 --> 00:17:14,160 suite of exploration technologies one is 344 00:17:19,590 --> 00:17:17,679 to use clocks by putting optical clocks 345 00:17:22,069 --> 00:17:19,600 in space free from the effects of 346 00:17:23,990 --> 00:17:22,079 gravity they become more precise clocks 347 00:17:25,909 --> 00:17:24,000 in space are more accurate than clocks 348 00:17:28,150 --> 00:17:25,919 here on the surface of the earth 349 00:17:31,510 --> 00:17:28,160 by having these clocks in space and 350 00:17:33,909 --> 00:17:31,520 having them operate so precisely we can 351 00:17:36,070 --> 00:17:33,919 monitor their frequency or their tick 352 00:17:38,549 --> 00:17:36,080 and look for deviations that are due to 353 00:17:42,150 --> 00:17:38,559 changes in gravity or the presence of 354 00:17:44,470 --> 00:17:42,160 tiny unseen forces 355 00:17:47,590 --> 00:17:44,480 we can also use the moon 356 00:17:50,070 --> 00:17:47,600 as a laboratory for exploration by using 357 00:17:52,549 --> 00:17:50,080 new laser ranging techniques we can make 358 00:17:55,190 --> 00:17:52,559 the moon a test mass and literally 359 00:17:57,669 --> 00:17:55,200 repeat the experiment that galileo did 360 00:17:59,669 --> 00:17:57,679 from the leaning tower of pisa and look 361 00:18:01,029 --> 00:17:59,679 and test the equivalence principle of 362 00:18:02,710 --> 00:18:01,039 gravity 363 00:18:04,150 --> 00:18:02,720 might shed light on many of these great 364 00:18:05,909 --> 00:18:04,160 questions 365 00:18:08,710 --> 00:18:05,919 we can also do 366 00:18:11,669 --> 00:18:08,720 create deep space quantum links where we 367 00:18:14,470 --> 00:18:11,679 use quantum mechanics itself 368 00:18:15,830 --> 00:18:14,480 to look for deviations and our 369 00:18:17,990 --> 00:18:15,840 understanding of these scientific 370 00:18:20,310 --> 00:18:18,000 theories perhaps revealing 371 00:18:22,310 --> 00:18:20,320 hidden variables or unseen 372 00:18:24,789 --> 00:18:22,320 new physics 373 00:18:27,590 --> 00:18:24,799 not directly to these questions but also 374 00:18:29,990 --> 00:18:27,600 equally important is we can use 375 00:18:32,870 --> 00:18:30,000 microgravity environments to explore 376 00:18:35,590 --> 00:18:32,880 dusty complex plasmas to reveal things 377 00:18:37,190 --> 00:18:35,600 about phase transitions and critical 378 00:18:40,390 --> 00:18:37,200 theories 379 00:18:43,029 --> 00:18:40,400 but we can also put atom interferometers 380 00:18:45,750 --> 00:18:43,039 in space this is where we take ultra 381 00:18:48,070 --> 00:18:45,760 cold atoms and we use their quantum 382 00:18:49,990 --> 00:18:48,080 mechanical wave nature 383 00:18:52,230 --> 00:18:50,000 to create an interferometer which 384 00:18:55,190 --> 00:18:52,240 becomes one of the most precise tools 385 00:18:56,470 --> 00:18:55,200 for measuring our physical universe 386 00:18:58,310 --> 00:18:56,480 so cal 387 00:19:01,669 --> 00:18:58,320 is one of those instruments that is 388 00:19:03,430 --> 00:19:01,679 pioneering this technique to explore the 389 00:19:06,310 --> 00:19:03,440 these great physical questions and to 390 00:19:09,350 --> 00:19:06,320 reveal potentially new physics and so 391 00:19:11,590 --> 00:19:09,360 today we are celebrating cal and i think 392 00:19:14,310 --> 00:19:11,600 this is a magnificent 393 00:19:20,220 --> 00:19:14,320 way to acknowledge our exploration into 394 00:19:20,230 --> 00:19:33,990 [Applause] 395 00:19:37,510 --> 00:19:35,350 good morning 396 00:19:41,190 -->

accomplishments 425 00:21:00,630 --> 00:20:57,510 professor eric cornell will talk about 426 00:21:03,190 --> 00:21:00,640 quantum science in space 427 00:21:05,110 --> 00:21:03,200 so um 428 00:21:07,270 --> 00:21:05,120 we're here today 429 00:21:10,230 --> 00:21:07,280 celebrating four years of quantum 430 00:21:12,390 --> 00:21:10,240 science in space 431 00:21:14,310 --> 00:21:12,400 because of tremendous 432 00:21:16,710 --> 00:21:14,320 uh determination 433 00:21:19,750 --> 00:21:16,720 and dedication by the people 434 00:21:21,029 --> 00:21:19,760 that actually proposed 435 00:21:22,789 --> 00:21:21,039 design 436 00:21:24,149 --> 00:21:22,799 built 437 00:21:26,149 --> 00:21:24,159 and now 438 00:21:28,149 --> 00:21:26,159 operating and using 439 00:21:31,110 --> 00:21:28,159 called adam lab 440 00:21:33,510 --> 00:21:31,120 we're also here 441 00:21:35,029 --> 00:21:33,520 to celebrate cals first and there are 442 00:21:36,950 --> 00:21:35,039 many and 443 00:21:40,070 --> 00:21:36,960 so you heard some of them 444 00:21:44,310 --> 00:21:42,070 there is still so much 445 00:21:46,230 --> 00:21:44,320 that we can still do in the quantum 446 00:21:47,750 --> 00:21:46,240 world so basically 447 00:21:50,950 --> 00:21:47,760 um 448 00:21:52,230 --> 00:21:50,960 we're not done yet so we this is four 449 00:21:54,070 --> 00:21:52,240 years and 450 00:21:57,990 --> 00:21:54,080 uh in space 451 00:22:00,870 --> 00:21:58,000 and we've been extended to operate until 452 00:22:03,190 --> 00:22:00,880 at least 2026 and this is made possible 453 00:22:05,510 --> 00:22:03,200 because of all the help and the support 454 00:22:08,070 --> 00:22:05,520 we get from 455 00:22:10,310 --> 00:22:08,080 also our crew office 456 00:22:14,870 --> 00:22:10,320 so 457 00:22:19,390 --> 00:22:16,870 it was launched 458 00:22:21,029 --> 00:22:19,400 to iss on may 21st 459 00:22:22,149 --> 00:22:21,039 2018 460 00:22:24,470 --> 00:22:22,159 on 461 00:22:29,029 --> 00:22:24,480 cygnus 462 00:22:30,390 --> 00:22:29,039 from wallops in virginia nasa's wallops 463 00:22:33,909 --> 00:22:30,400 and 464 00:22:35,990 --> 00:22:33,919 we took about a few months to perform 465 00:22:39,350 --> 00:22:36,000 what we call commissioning 466 00:22:40,549 --> 00:22:39,360 and we started our science operations 467 00:22:42,149 --> 00:22:40,559 around 468 00:22:45,590 --> 00:22:42,159 this time august 469 00:22:48,390 --> 00:22:45,600 2018 so we've been operating in space 470 00:22:50,710 --> 00:22:48,400 since so in a sense if 471 00:22:51,909 --> 00:22:50,720 i want you to remember so the called 472 00:22:52,950 --> 00:22:51,919 adam lab 473 00:22:54,390 --> 00:22:52,960 is 474 00:22:55,669 --> 00:22:54,400 a laboratory 475 00:22:57,750 --> 00:22:55,679 orbiting 476 00:22:59,190 --> 00:22:57,760 earth 477 00:23:00,870 --> 00:22:59,200 operated 478 00:23:05,270 --> 00:23:00,880 remotely 479 00:23:09,029 --> 00:23:07,510 the coal atom lab 480 00:23:11,350 --> 00:23:09,039 is the size of 481 00:23:12,310 --> 00:23:11,360 like a mini refrigerator so if if you 482 00:23:15,430 --> 00:23:12,320 can see 483 00:23:18,870 --> 00:23:15,440 astronaut christina coke she's facing 484 00:23:20,070 --> 00:23:18,880 the science instrument which fits in uh 485 00:23:23,190 --> 00:23:20,080 four quarter 486 00:23:24,789 --> 00:23:23,200 one four quadrant and then we have all 487 00:23:27,510 --> 00:23:24,799 the power electronics and so on in a 488 00:23:28,630 --> 00:23:27,520 single locker 489 00:23:29,430 --> 00:23:28,640 so 490 00:23:30,549 --> 00:23:29,440 um 491 00:23:33,430 --> 00:23:30,559 in a sense 492 00:23:36,470 --> 00:23:33,440 the called atom lab is the first quantum 493 00:23:40,950 --> 00:23:36,480 science laboratory in space 494 00:23:43,590 --> 00:23:40,960 that is remotely operated from earth 495 00:23:45,909 --> 00:23:43,600 in terms of cold when we think about a 496 00:23:48,710 --> 00:23:45,919 cold place on earth we think of 497 00:23:50,950 --> 00:23:48,720 antarctica for example right 498 00:23:53,909 --> 00:23:50,960 with a temperature of 499 00:23:56,390 --> 00:23:53,919 like in a winter night of minus 83 500 00:23:59,269 --> 00:23:56,400 degree celsius 501 00:24:03,510 --> 00:23:59,279 or if we think of the moon 502 00:24:06,390 --> 00:24:03,520 the far side of the moon is about minus 503 00:24:07,669 --> 00:24:06,400 173 504 00:24:10,310 --> 00:24:07,679 but all this 505 00:24:12,310 --> 00:24:10,320 doesn't come close to the temperatures 506 00:24:14,390 --> 00:24:12,320 that we daily 507 00:24:17,269 --> 00:24:14,400 uh generate 508 00:24:19,510 --> 00:24:17,279 or achieve with the cold atom lab 509 00:24:21,590 --> 00:24:19,520 and 510 00:24:23,669 --> 00:24:21,600 even if we compare to space now i'm 511 00:24:24,630 --> 00:24:23,679 going to shift a little bit the unit so 512 00:24:28,710 --> 00:24:24,640 space 513 00:24:29,909 --> 00:24:28,720 has an average of 3 kelvin temperature 514 00:24:32,470 --> 00:24:29,919 and 515 00:24:36,390 --> 00:24:32,480 with the cold atom as you will hear in 516 00:24:38,149 --> 00:24:36,400 in a few minutes we've been able to 517 00:24:39,269 --> 00:24:38,159 achieve 518 00:24:41,510 --> 00:24:39,279 minus 519 00:24:42,630 --> 00:24:41,520 52 pico kelvins 520 00:24:44,789 --> 00:24:42,640 and 521 00:24:49,430 --> 00:24:44,799 most of our experiments 522 00:24:52,630 --> 00:24:49,440 use about 100 100 nano nano kelvins 523 00:24:53,830 --> 00:24:52,640 so there is a huge difference and that's 524 00:24:56,390 --> 00:24:53,840 why 525 00:25:00,789 --> 00:24:56,400 when you look up and look at iss it's 526 00:25:04,310 --> 00:25:00,799 basically the coldest spot in space 527 00:25:05,669 --> 00:25:04,320 so i want you to remember the 50 to 52 528 00:25:09,269 --> 00:25:05,679 pico kelvin 529 00:25:11,110 --> 00:25:09,279 um done with the cold atom lab 530 00:25:15,430 --> 00:25:11,120 so what you're looking at here 531 00:25:17,909 --> 00:25:15,440 on the top left that's a typical 532 00:25:19,350 --> 00:25:17,919 called atom laboratory 533 00:25:21,750 --> 00:25:19,360 here on earth 534 00:25:22,870 --> 00:25:21,760 you see lasers 535 00:25:24,549 --> 00:25:22,880 electronic 536 00:25:26,070 --> 00:25:24,559 for controlling 537 00:25:29,750 --> 00:25:26,080 optics 538 00:25:31,669 --> 00:25:29,760 the ultra vacuum 539 00:25:34,470 --> 00:25:31,679 there these types of experiments are 540 00:25:37,590 --> 00:25:34,480 considered the most complex 541 00:25:39,590 --> 00:25:37,600 uh tabletop experiments on earth 542 00:25:42,789 --> 00:25:39,600 and what you don't see here actually it 543 00:25:45,830 --> 00:25:42,799 usually requires multiple people to run 544 00:25:48,310 --> 00:25:45,840 this kind of experiments because 545 00:25:50,310 --> 00:25:48,320 they're really hard to keep running 546 00:25:52,310 --> 00:25:50,320 smoothly and and if i'm saying this 547 00:25:55,590 --> 00:25:52,320 because i've had a chance to talk to so 548 00:25:58,230 --> 00:25:55,600 many physicists and and they acknowledge 549 00:26:01,669 --> 00:25:58,240 this and the challenge we had 550 00:26:02,789 --> 00:26:01,679 and this is almost like to to to 551 00:26:04,470 --> 00:26:02,799 to scale 552 00:26:06,310 --> 00:26:04,480 is basically 553 00:26:10,470 --> 00:26:06,320 take all this stuff 554 00:26:13,350 --> 00:26:10,480 and make it fit in a small box on top of 555 00:26:14,230 --> 00:26:13,360 this it has you had to 556 00:26:17,510 --> 00:26:14,240 be 557 00:26:20,230 --> 00:26:17,520 operated remotely 558 00:26:26,149 --> 00:26:22,789 some of this 559 00:26:29,590 --> 00:26:26,159 you know challenges also involved 560 00:26:31,350 --> 00:26:29,600 how we would deal with the repairs 561 00:26:33,430 --> 00:26:31,360 so in a sense 562 00:26:35,510 --> 00:26:33,440 it took a lot of 563 00:26:38,070 --> 00:26:35,520 hard-working people and especially i see 564 00:26:40,149 --> 00:26:38,080 around like students so many disciplines 565 00:26:44,390 --> 00:26:40,159 electrical engineers 566 00:26:46,789 --> 00:26:44,400 mechanical systems thermal it takes many 567 00:26:49,669 --> 00:26:46,799 different disciplines to to make a 568 00:26:52,390 --> 00:26:49,679 mission like cal successful and we've 569 00:26:54,549 --> 00:26:52,400 been as you heard operating 570 00:26:56,950 --> 00:26:54,559 in space for four years 571 00:27:00,630 --> 00:26:56,960 and luckily the the idea of the design 572 00:27:02,549 --> 00:27:00,640 of this modular approach also has uh 573 00:27:04,950 --> 00:27:02,559 helped us a lot and in a little bit of 574 00:27:07,669 --> 00:27:04,960 time so what you see here uh it's the 575 00:27:09,430 --> 00:27:07,679 same uh part of the instrument of the 576 00:27:10,950 --> 00:27:09,440 science instrument that's this that's 577 00:27:13,430 --> 00:27:10,960 the science 578 00:27:16,390 --> 00:27:13,440 uh module and that's where all the 579 00:27:18,870 --> 00:27:16,400 science happens and at the heart of this 580 00:27:21,510 --> 00:27:18,880 uh science module there is the physics 581 00:27:23,590 --> 00:27:21,520 package and this uh 582 00:27:25,590 --> 00:27:23,600 ultra sensitive vacuum as i mentioned 583 00:27:26,950 --> 00:27:25,600 and we did it in collaboration with with 584 00:27:29,909 --> 00:27:26,960 our 585 00:27:31,750 --> 00:27:29,919 partner uh cole quanta 586 00:27:35,350 --> 00:27:31,760 played an important role also in the 587 00:27:38,789 --> 00:27:35,360 success of cal 588 00:27:42,389 --> 00:27:38,799 so you heard uh john quickly mentioned 589 00:27:44,149 --> 00:27:42,399 about the the fact that why space i mean 590 00:27:46,950 --> 00:27:44,159 you can think of it like when you see 591 00:27:49,909 --> 00:27:46,960 astronauts floating right that's the 592 00:27:51,909 --> 00:27:49,919 same kind of idea what happens when we 593 00:27:53,909 --> 00:27:51,919 call atoms so 594 00:27:56,470 --> 00:27:53,919 when they float 595 00:27:58,549 --> 00:27:56,480 we get to observe them at longer period 596 00:28:00,789 --> 00:27:58,559 of time so basically the bose einstein 597 00:28:03,430 --> 00:28:00,799 condensate have been produced on earth 598 00:28:05,590 --> 00:28:03,440 and actually the first person to ever do 599 00:28:09,990 --> 00:28:05,600 it is here with us this is professor 600 00:28:11,190 --> 00:28:10,000 eric cornell on the ground 1985 and the 601 00:28:14,310 --> 00:28:11,200 idea 602 00:28:16,470 --> 00:28:14,320 is because of gravity uh it limits the 603 00:28:19,990 --> 00:28:16,480 the amount of time that we can observe 604 00:28:22,630 --> 00:28:20,000 this this uh ultra cold atom so by going 605 00:28:27,350 --> 00:28:22,640 to space it helps us 606 00:28:29,590 --> 00:28:27,360 to observe it at longer time and also 607 00:28:33,110 --> 00:28:29,600 this kind of sensors that just john 608 00:28:35,669 --> 00:28:33,120 talked about dark matter dark energy 609 00:28:38,630 --> 00:28:35,679 on top of this there's some applications 610 00:28:40,950 --> 00:28:38,640 especially we here at jpl we're so 611 00:28:42,230 --> 00:28:40,960 involved in planetary science so it can 612 00:28:44,389 --> 00:28:42,240 improve 613 00:28:47,909 --> 00:28:44,399 sensors for navigation 614 00:28:49,990 --> 00:28:47,919 and also um you know for gravity and and 615 00:28:51,110 --> 00:28:50,000 understanding interest structures of 616 00:28:54,470 --> 00:28:51,120 planets 617 00:28:58,870 --> 00:28:54,480 and uh additionally it can even help us 618 00:29:00,310 --> 00:28:58,880 uh study earth's climate 619 00:29:02,389 --> 00:29:00,320 and 620 00:29:04,230 --> 00:29:02,399 sorry 621 00:29:07,430 --> 00:29:04,240 so what you're seeing that's like a 622 00:29:10,470 --> 00:29:07,440 cloud of atoms we usually use lasers to 623 00:29:13,590 --> 00:29:10,480 slow down the atoms and then also we use 624 00:29:14,470 --> 00:29:13,600 magnetic traps to control them 625 00:29:18,789 --> 00:29:14,480 and 626 00:29:20,630 --> 00:29:18,799 magnetic traps 627 00:29:22,789 --> 00:29:20,640 allows us to 628 00:29:24,230 --> 00:29:22,799 reach lower temperatures in microgravity 629 00:29:26,789 --> 00:29:24,240 compared to earth 630 00:29:29,110 --> 00:29:26,799 all right so what you're looking here 631 00:29:30,950 --> 00:29:29,120 and this is not something i'm going to 632 00:29:35,110 --> 00:29:30,960 go over because that's going to be like 633 00:29:37,669 --> 00:29:35,120 the focus of professor eric cornell's um 634 00:29:39,590 --> 00:29:37,679 talk but this is just the bose einstein 635 00:29:41,669 --> 00:29:39,600 condensate so would like you to remember 636 00:29:44,070 --> 00:29:41,679 from this first 637 00:29:45,510 --> 00:29:44,080 bose and einstein 638 00:29:48,549 --> 00:29:45,520 thought about this 639 00:29:49,909 --> 00:29:48,559 almost 100 years ago in 1920s 640 00:29:53,430 --> 00:29:49,919 and they they 641 00:29:55,190 --> 00:29:53,440 published a paper that if you can cool 642 00:29:58,549 --> 00:29:55,200 atoms to very 643 00:30:01,269 --> 00:29:58,559 ultra cold temperatures 644 00:30:02,710 --> 00:30:01,279 these particles start behaving like 645 00:30:04,549 --> 00:30:02,720 waves 646 00:30:06,549 --> 00:30:04,559 and 647 00:30:08,630 --> 00:30:06,559 if you 648 00:30:11,190 --> 00:30:08,640 lower their temperature further 649 00:30:13,750 --> 00:30:11,200 these waves combine or collapse in a 650 00:30:15,110 --> 00:30:13,760 single wave and uh 651 00:30:16,870 --> 00:30:15,120 they become they both einstein 652 00:30:18,230 --> 00:30:16,880 condensate 653 00:30:20,950 --> 00:30:18,240 and 654 00:30:23,190 --> 00:30:20,960 the idea this you can think of it like a 655 00:30:27,430 --> 00:30:23,200 it's a different form of state of matter 656 00:30:27,440 --> 00:30:29,830 and 657 00:30:32,389 --> 00:30:30,950 solids 658 00:30:34,149 --> 00:30:32,399 and plasma 659 00:30:36,230 --> 00:30:34,159 this is the fifth state of matter it's 660 00:30:37,990 --> 00:30:36,240 both einstein columnist why this is 661 00:30:41,190 --> 00:30:38,000 important because think of the called 662 00:30:43,269 --> 00:30:41,200 adam lab every day when our team shows 663 00:30:44,789 --> 00:30:43,279 up to the 664 00:30:47,909 --> 00:30:44,799 operations room 665 00:30:50,470 --> 00:30:47,919 their idea or their primary objective is 666 00:30:53,350 --> 00:30:50,480 to make the machine or the cold atom lab 667 00:30:54,789 --> 00:30:53,360 create these bose einstein condensates 668 00:30:57,590 --> 00:30:54,799 which 669 00:30:59,750 --> 00:30:57,600 almost like looking 670 00:31:03,430 --> 00:30:59,760 at a 671 00:31:05,990 --> 00:31:03,440 quantum in a macroscopic level 672 00:31:09,029 --> 00:31:06,000 and they use this bose einstein 673 00:31:11,990 --> 00:31:09,039 condensate to do their science so 674 00:31:13,029 --> 00:31:12,000 we have we're supporting about five 675 00:31:14,710 --> 00:31:13,039 uh 676 00:31:16,389 --> 00:31:14,720 science teams 677 00:31:19,110 --> 00:31:16,399 and the idea is 678 00:31:21,750 --> 00:31:19,120 they expect us to to produce this uh 679 00:31:24,789 --> 00:31:21,760 level of bose einstein constant and they 680 00:31:27,029 --> 00:31:24,799 use this interesting matter as i said to 681 00:31:29,269 --> 00:31:27,039 to do their experiment and just because 682 00:31:31,430 --> 00:31:29,279 five teams are working on cal right now 683 00:31:33,190 --> 00:31:31,440 that doesn't mean that we can have more 684 00:31:35,430 --> 00:31:33,200 many people 685 00:31:37,350 --> 00:31:35,440 use the same kind of 686 00:31:39,750 --> 00:31:37,360 fifth state of matter to to create their 687 00:31:41,750 --> 00:31:39,760 own experiments in the future 688 00:31:44,230 --> 00:31:41,760 and um 689 00:31:48,870 --> 00:31:44,240 and that sums up what i wanted to say 690 00:31:48,880 --> 00:31:52,950 take a minute to introduce 691 00:31:52,960 --> 00:31:57,190 our 692 00:31:59,590 --> 00:31:58,549 distinguished

00:32:57,519 and actually i found out that juno was 720 00:33:02,230 --> 00:33:00,320 par part of this nasa missions 721 00:33:04,310 --> 00:33:02,240 in june 2013 722 00:33:07,110 --> 00:33:04,320 christina was selected 723 00:33:08,950 --> 00:33:07,120 as one of the eight members of the 21st 724 00:33:11,750 --> 00:33:08,960 nasa astronaut class 725 00:33:14,870 --> 00:33:11,760 in 2018 she was assigned to her first 726 00:33:17,830 --> 00:33:14,880 space flight a long duration mission on 727 00:33:20,149 --> 00:33:17,840 the international space station 728 00:33:24,710 --> 00:33:20,159 she was a part of iss 729 00:33:27,669 --> 00:33:24,720 expeditions 59 60 and 61. she has 730 00:33:30,549 --> 00:33:27,679 conducted six spacewalks including the 731 00:33:33,269 --> 00:33:30,559 first three all-women spacewalks 732 00:33:35,669 --> 00:33:33,279 totaling 42 hours and 15 minutes 733 00:33:38,470 --> 00:33:35,679 christina has also set a record for the 734 00:33:42,710 --> 00:33:38,480 longest single space flight by a woman 735 00:33:44,630 --> 00:33:42,720 with a total of 328 days in space 736 00:33:47,509 --> 00:33:44,640 throughout her career 737 00:33:49,909 --> 00:33:47,519 she has been involved in the electrical 738 00:33:53,110 --> 00:33:49,919 uh sorry technical instructing 739 00:33:54,310 --> 00:33:53,120 volunteers tutoring and educational 740

just give you a little 754 00:34:32,710 --> 00:34:30,560 perspective because you've heard about 755 00:34:34,950 --> 00:34:32,720 the upgrade to the cow 756 00:34:37,909 --> 00:34:34,960 because the cold atom lab when it was 757 00:34:40,470 --> 00:34:37,919 launched it was it did not include atom 758 00:34:42,310 --> 00:34:40,480 interferometry which is a like john 759 00:34:44,790 --> 00:34:42,320 mentioned it's a critical 760 00:34:46,149 --> 00:34:44,800 part of our science tools to help us 761 00:34:50,869 --> 00:34:46,159 study the 762 00:34:51,750 --> 00:34:50,879 struggle 763 00:34:57,829 --> 00:34:51,760 um 764 00:35:00,390 --> 00:34:57,839 and uh do the the upgrade here and that 765 00:35:04,630 --> 00:35:00,400 was like some people highly recommend 766 00:35:06,950 --> 00:35:04,640 that we do this or we turn uh and rely 767 00:35:08,230 --> 00:35:06,960 and put our fates in the hand of 768 00:35:09,990 --> 00:35:08,240 astronauts 769 00:35:11,829 --> 00:35:10,000 and uh 770 00:35:13,190 --> 00:35:11,839 see if it can work 771 00:35:15,190 --> 00:35:13,200 but we did 772 00:35:17,190 --> 00:35:15,200 we were told it was going to be 50 773 00:35:19,030 --> 00:35:17,200 chance 774 00:35:21,510 --> 00:35:19,040 sorry but the problem had we brought it 775 00:35:24,790 --> 00:35:21,520 back it would take we would be down for 776 00:35:28,550 --> 00:35:24,800 at least two years on the ground 777 00:35:31,349 --> 00:35:28,560 we our stars uh lined up lucky star so 778 00:35:34,710 --> 00:35:31,359 to speak and we 779 00:35:36,470 --> 00:35:34,720 were so lucky to have uh astronaut 780 00:35:37,829 --> 00:35:36,480 christina cook 781 00:35:39,589 --> 00:35:37,839 who 782 00:35:41,270 --> 00:35:39,599 when we 783 00:35:43,510 --> 00:35:41,280 looked at all the work she had done we 784 00:35:45,030 --> 00:35:43,520 knew that we had a good chance 785 00:35:46,870 --> 00:35:45,040 and 786 00:35:49,670 --> 00:35:46,880 we watch her 787 00:35:52,470 --> 00:35:49,680 we work you know like from the ground 788 00:35:55,109 --> 00:35:52,480 and she did an amazing job 789 00:35:56,230 --> 00:35:55,119 and and we and once again as i said we 790 00:35:58,790 --> 00:35:56,240 had no 791 00:36:01,030 --> 00:35:58,800 there is no uh chance for 792 00:36:02,790 --> 00:36:01,040 any errors or anything because it's a 793 00:36:05,030 --> 00:36:02,800 science instrument which means it's a 794 00:36:07,829 --> 00:36:05,040 single string like there is no 795 00:36:08,710 --> 00:36:07,839 redundancy and she did it in a record 796 00:36:12,230 --> 00:36:08,720 time 797 00:36:14,950 --> 00:36:12,240 and because of her amazing work we would 798 00:36:18,950 --> 00:36:14,960 like to take a moment on behalf of 799 00:36:20,710 --> 00:36:18,960 jpl to thank her for all her exceptional 800 00:36:24,550 --> 00:36:20,720 work and i'm going to read the plaque 801 00:36:28,550 --> 00:36:24,560 and i will ask our doctor 802 00:36:31,910 --> 00:36:28,560 claire patel uh director for astronomy 803 00:36:34,150 --> 00:36:31,920 physics to hand her 804 00:36:35,750 --> 00:36:34,160 this plaque but i just want to go ahead 805 00:36:37,190 --> 00:36:35,760 and read it if you allow me 806 00:36:39,510 --> 00:36:37,200 presented 807 00:36:41,589 --> 00:36:39,520 to astronaut christina koch 808 00:36:43,829 --> 00:36:41,599 for your exceptional support to enable 809 00:36:46,230 --> 00:36:43,839 the upgrade of the called adam lab with 810 00:36:47,910 --> 00:36:46,240 adam interferometry in space from your 811 00:36:50,080 --> 00:36:47,920 friends at nasa's jet propulsion 812 00:37:00,390 --> 00:36:50,090 laboratory 813 00:37:10,470 --> 00:37:00,400 [Applause] 814 00:37:10,480 --> 00:37:20,950 okay sorry so

feel like i was the one that my lucky 818 00:37:33,670 --> 00:37:30,880 stars aligned so that i could be a part 819 00:37:35,510 --> 00:37:33,680 of cold adam lab and actually what i'm 820 00:37:37,670 --> 00:37:35,520 going to talk about today is is that 821 00:37:40,710 --> 00:37:37,680 whole story so i won't go into it now 822 00:37:43,190 --> 00:37:40,720 but it is such an honor to be here with 823 00:37:44,550 --> 00:37:43,200 you all to share this stage with these 824 00:37:46,950 --> 00:37:44,560 amazing people 825 00:37:49,670 --> 00:37:46,960 and just to be in your presence i 826 00:37:52,150 --> 00:37:49,680 definitely let my nerd flag fly often 827 00:37:54,310 --> 00:37:52,160 and jpl has always been a place that was 828 00:37:56,150 --> 00:37:54,320 kind of a beacon for me 829 00:37:57,990 --> 00:37:56,160 in that regard and it's just any time i 830 00:37:59,589 --> 00:37:58,000 can get here is a wonderful day and 831 00:38:00,870 --> 00:37:59,599 anytime i can work with the teams here 832 00:38:04,069 --> 00:38:00,880 is even better 833 00:38:05,829 --> 00:38:04,079 so often times when i speak i i just 834 00:38:07,109 --> 00:38:05,839 talk about my mission my journey how i 835 00:38:09,829 --> 00:38:07,119 got to space 836 00:38:12,710 --> 00:38:09,839 um and today it's a little bit more 837 00:38:14,069 --> 00:38:12,720 targeted i'm going to talk about how i 838 00:38:15,750 --> 00:38:14,079 became 839 00:38:18,870 --> 00:38:15,760 the space 840 00:38:20,790 --> 00:38:18,880 cold adam lab repair guy 841 00:38:22,870 --> 00:38:20,800 that was the real journey that was going 842 00:38:24,950 --> 00:38:22,880 on it turns out my entire career and i'm 843 00:38:27,349 --> 00:38:24,960 going to show you why 844 00:38:29,430 --> 00:38:27,359 so i started a straight out of college 845 00:38:32,470 --> 00:38:29,440 at goddard space flight center in a lab 846 00:38:35,349 --> 00:38:32,480 that did super conducting uh sensors for 847 00:38:36,870 --> 00:38:35,359 astrophysics and i had to learn how to 848 00:38:38,950 --> 00:38:36,880 work with liquid helium and liquid 849 00:38:41,829 --> 00:38:38,960 nitrogen and so this was back in the day 850 00:38:44,150 --> 00:38:41,839 when i thought 4 kelvin was cold maybe 6 851 00:38:46,230 --> 00:38:44,160 3 micro kelvin was cold 852 00:38:49,109 --> 00:38:46,240 that obviously all changed throughout my 853 00:38:51,430 --> 00:38:49,119 journey um and actually it started even 854 00:38:54,230 --> 00:38:51,440 before this because when i was in grad 855 00:38:56,069 --> 00:38:54,240 school i actually got to do all of those 856 00:38:58,230 --> 00:38:56,079 wave equations for 857 00:39:00,550 --> 00:38:58,240 bose-einstein condensates and i remember 858 00:39:03,670 --> 00:39:00,560 thinking at that time wow 859 00:39:06,630 --> 00:39:03,680 i'm never going to use this 860 00:39:09,030 --> 00:39:06,640 but i'm i i have to report that after 861 00:39:11,270 --> 00:39:09,040 having worked on cold adam lab 862 00:39:15,030 --> 00:39:11,280 i still have never used it 863 00:39:16,710 --> 00:39:15,040 but i at least knew how to spell um bcs 864 00:39:19,750 --> 00:39:16,720 by then because i had done that work in 865 00:39:21,750 --> 00:39:19,760 grad school um but it turns out after 866 00:39:24,390 --> 00:39:21,760 working in a laboratory on earth that 867 00:39:26,230 --> 00:39:24,400 did a lot of cryogenics i needed to then 868 00:39:27,750 --> 00:39:26,240 be at the coldest place on earth so i 869 00:39:29,270 --> 00:39:27,760 worked at the south pole station in 870 00:39:31,030 --> 00:39:29,280 antarctica for a while this is where 871 00:39:33,270 --> 00:39:31,040 science on the frontiers really first 872 00:39:35,829 --> 00:39:33,280 started energizing what would become my 873 00:39:38,230 --> 00:39:35,839 career path and i was actually the 874 00:39:40,230 --> 00:39:38,240 cryogenics technician of the south pole 875 00:39:42,630 --> 00:39:40,240 station our motto was when the south 876 00:39:45,510 --> 00:39:42,640 pole just isn't cold enough come to us 877 00:39:47,349 --> 00:39:45,520 and we did have a liquid helium thing 878 00:39:49,829 --> 00:39:47,359 again to enable astrophysics that 879 00:39:52,310 --> 00:39:49,839 happens there 880 00:39:54,069 --> 00:39:52,320 i worked in some missions at the applied 881 00:39:56,630 --> 00:39:54,079 physics lab always with the space 882 00:39:59,589 --> 00:39:56,640 science and instrumentation in mind and 883 00:40:02,150 --> 00:39:59,599 oftentimes also in very cold places and 884 00:40:04,790 --> 00:40:02,160 that's when i found myself here having 885 00:40:08,150 --> 00:40:04,800 been selected as a very lucky member of 886 00:40:10,230 --> 00:40:08,160 the 2013 astronaut class and soon after 887 00:40:12,309 --> 00:40:10,240 we got started into our what we call 888 00:40:13,990 --> 00:40:12,319 astronaut candidate training so this was 889 00:40:15,430 --> 00:40:14,000 where i learned a whole lot of different 890 00:40:17,430 --> 00:40:15,440 career paths and things that i would 891 00:40:19,190 --> 00:40:17,440 have to do to eventually be the cold 892 00:40:22,309 --> 00:40:19,200 adam lab repair guy 893 00:40:24,390 --> 00:40:22,319 including how to fly a supersonic jet 894 00:40:25,910 --> 00:40:24,400 how to do space walking which we learn 895 00:40:27,349 --> 00:40:25,920 in our gigantic 896 00:40:29,430 --> 00:40:27,359 pool facility called the neutral 897 00:40:31,270 --> 00:40:29,440 buoyancy lab that has an entire mock-up 898 00:40:33,430 --> 00:40:31,280 of the space station underwater so that 899 00:40:36,230 --> 00:40:33,440 we can practice this work 900 00:40:38,470 --> 00:40:36,240 and even during our time learning how to 901 00:40:40,150 --> 00:40:38,480 become astronauts my astronaut class got 902 00:40:42,390 --> 00:40:40,160 to visit jpl so that was a really 903 00:40:44,230 --> 00:40:42,400 exciting time we saw the mars yard we 904 00:40:45,589 --> 00:40:44,240 got to do the fundamental physics tour 905 00:40:46,870 --> 00:40:45,599 as well 906 00:40:48,309 --> 00:40:46,880 and eventually i got my flight 907 00:40:49,990 --> 00:40:48,319 assignment and that's when we go into 908 00:40:51,990 --> 00:40:50,000 flight specific 909 00:40:53,910 --> 00:40:52,000 training this is us training on some of 910 00:40:55,430 --> 00:40:53,920 the other science that we do onboard the 911 00:40:57,109 --> 00:40:55,440 space station 912 00:40:59,030 --> 00:40:57,119 and this is actually the first time i 913 00:41:01,109 --> 00:40:59,040 learned about cold adam lab and i 914 00:41:02,470 --> 00:41:01,119 remember thinking wow if i get to work 915 00:41:04,309 --> 00:41:02,480 on that when i'm up there that would be 916 00:41:06,630 --> 00:41:04,319 really cool think of everything i've 917 00:41:07,510 --> 00:41:06,640 done this is the obvious next step for 918 00:41:12,309 --> 00:41:07,520 me 919 00:41:13,910 --> 00:41:12,319 claims and is the coldest spot in the 920 00:41:15,910 --> 00:41:13,920 universe so that was that was an 921 00:41:17,829 --> 00:41:15,920 exciting possibility but i was told that 922 00:41:19,430 --> 00:41:17,839 no one ever really works on that that's 923 00:41:20,870 --> 00:41:19,440 something that astronauts don't actually 924 00:41:22,870 --> 00:41:20,880 get to interact with because as you've 925 00:41:25,349 --> 00:41:22,880 learned the experts usually can run it 926 00:41:27,589 --> 00:41:25,359 directly from the ground and so i knew 927 00:41:29,670 --> 00:41:27,599 that i would have to get really lucky 928 00:41:31,430 --> 00:41:29,680 and have an opportunity for an upgrade 929 00:41:33,589 --> 00:41:31,440 or something like that 930 00:41:35,430 --> 00:41:33,599 kept on training i was an astronaut that 931 00:41:37,510 --> 00:41:35,440 launched on a soyuz rocket out of 932 00:41:39,109 --> 00:41:37,520 kazakhstan it's a russian rocket so part 933 00:41:42,150 --> 00:41:39,119 of my training and actually quite a bit 934 00:41:45,430 --> 00:41:42,160 of it was in russia and then came this 935 00:41:52,069 --> 00:41:48,950 the actual launch day and 936 00:41:53,750 --> 00:41:52,079 eight minutes later finding yourself 937 00:41:55,750 --> 00:41:53,760 in microgravity 938 00:41:58,150 --> 00:41:55,760 when that third stage cuts off and you 939 00:41:59,109 --> 00:41:58,160 float a little bit out of your seat and 940 00:42:03,270 --> 00:41:59,119 you know 941 00:42:05,589 --> 00:42:03,280 you are one step closer to cold adam lab 942 00:42:07,589 --> 00:42:05,599 the spacecraft obviously becomes a free 943 00:42:09,270 --> 00:42:07,599 flyer for just a little while we end up 944 00:42:10,630 --> 00:42:09,280 at the space station about six hours 945 00:42:13,990 --> 00:42:10,640 after launch if you can believe it it's 946 00:42:16,470 --> 00:42:14,000 pretty quick and that 947 00:42:18,950 --> 00:42:16,480 hatch here is what actually docks and 948 00:42:21,829 --> 00:42:18,960 it's the hatch that we open to enter the 949 00:42:24,309 --> 00:42:21,839 space station and meet our friends 950 00:42:25,990 --> 00:42:24,319 so life on board is a lot of 951 00:42:27,270 --> 00:42:26,000 it's a combination of a lot of things 952 00:42:28,870 --> 00:42:27,280 obviously we all know that the main 953 00:42:30,870 --> 00:42:28,880 mission of the space station is to be a 954 00:42:32,630 --> 00:42:30,880 national lab that does the science that 955 00:42:34,630 --> 00:42:32,640 can only be done in that space 956 00:42:36,309 --> 00:42:34,640 environment but to keep it running that 957 00:42:38,710 --> 00:42:36,319 involves a lot of maintenance most of 958 00:42:40,550 --> 00:42:38,720 which is on you know racks that do all 959 00:42:41,910 --> 00:42:40,560 of our life support systems all of our 960 00:42:43,670 --> 00:42:41,920 avionics 961 00:42:45,430 --> 00:42:43,680 sometimes we get lucky and for an 962 00:42:47,109 --> 00:42:45,440 electrical engineer we get to do some of 963 00:42:49,670 --> 00:42:47,119 the board level 964 00:42:51,589 --> 00:42:49,680 work and and repair this is one example 965 00:42:53,990 --> 00:42:51,599 of those times 966 00:42:55,990 --> 00:42:54,000 and then other things when visiting 967 00:42:58,390 --> 00:42:56,000 cargo vehicles come we actually operate 968 00:42:59,430 --> 00:42:58,400 the robotic arm to bring them aboard and 969 00:43:01,349 --> 00:42:59,440 to make sure that we can get those 970 00:43:03,349 --> 00:43:01,359 supplies some of which are the new 971 00:43:05,829 --> 00:43:03,359 science experiments 972 00:43:08,870 --> 00:43:05,839 and of course spacewalking so this is uh 973 00:43:11,430 --> 00:43:08,880 jessica mir and i who we were honored to 974 00:43:13,270 --> 00:43:11,440 be uh the the two astronauts that got to 975 00:43:15,109 --> 00:43:13,280 do the first ever spacewalk that was 976 00:43:17,190 --> 00:43:15,119 conducted by two women first of all 977 00:43:19,670 --> 00:43:17,200 female spacewalk and we got to go out 978 00:43:22,069 --> 00:43:19,680 and do that three times together 979 00:43:24,150 --> 00:43:22,079 and that is truly just one of the gems 980 00:43:25,910 --> 00:43:24,160 for any astronaut being able to enable 981 00:43:27,910 --> 00:43:25,920 the space you know the science to 982 00:43:30,069 --> 00:43:27,920 continue on the space station by 983 00:43:31,829 --> 00:43:30,079 upgrading and repairing the outside of 984 00:43:33,270 --> 00:43:31,839 the space station 985 00:43:35,589 --> 00:43:33,280 we also love the international 986 00:43:37,430 --> 00:43:35,599 collaborative uh aspect of the space 987 00:43:39,589 --> 00:43:37,440 station it's one in my opinion of its 988 00:43:41,510 --> 00:43:39,599 its loftiest goals and its loftiest 989 00:43:43,430 --> 00:43:41,520 achievements and this is me working with 990 00:43:45,109 --> 00:43:43,440 my actual russian commander alexei of 991 00:43:48,630 --> 00:43:45,119 chinen preparing for one of his 992 00:43:49,750 --> 00:43:48,640 spacewalks that i got to help with 993 00:43:52,630 --> 00:43:49,760 and now 994 00:43:55,990 --> 00:43:52,640 a little bit about the science so this 995 00:43:57,589 --> 00:43:56,000 is a video um that we put together as a 996 00:43:59,030 --> 00:43:57,599 compilation of a lot of the different 997 00:44:00,710 --> 00:43:59,040 science and i'm going to narrate it the 998 00:44:03,190 --> 00:44:00,720 actual video has some music so bear with 999 00:44:05,589 --> 00:44:03,200 me one of the life sciences experiments 1000 00:44:07,589 --> 00:44:05,599 that we do is the plant work and in this 1001 00:44:09,510 --> 00:44:07,599 video you hear me enter talking back and 1002 00:44:11,190 --> 00:44:09,520 forth with the folks on the ground about 1003 00:44:12,550 --> 00:44:11,200 how much water to actually put in each 1004 00:44:13,990 --> 00:44:12,560 of the plants 1005 00:44:15,750 --> 00:44:14,000 and one of my favorite things about 1006 00:44:17,510 --> 00:44:15,760 working in space is you feel like you 1007 00:44:20,150 --> 00:44:17,520 have your lab partner on the ground and 1008 00:44:21,430 --> 00:44:20,160 you really have a great relationship 1009 00:44:24,550 --> 00:44:21,440 with that person that you're working 1010 00:44:26,790 --> 00:44:24,560 with um i got to talk to jim jim kellogg 1011 00:44:28,790 --> 00:44:26,800 from this cold adam lab 1012 00:44:31,109 --> 00:44:28,800 for for days working on working on it 1013 00:44:33,910 --> 00:44:31,119 together and you really you you get to 1014 00:44:35,670 --> 00:44:33,920 feel like you are a part of that team 1015 00:44:37,349 --> 00:44:35,680 jessica and i again working on our plant 1016 00:44:39,510 --> 00:44:37,359 lab 1017 00:44:41,190 --> 00:44:39,520 this is an experiment with tissue chips 1018 00:44:43,589 --> 00:44:41,200 so actually doing some biological 1019 00:44:45,430 --> 00:44:43,599 experiments on a chip that's able to 1020 00:44:47,109 --> 00:44:45,440 represent some of the mechanics of our 1021 00:44:49,030 --> 00:44:47,119 of our biological systems that we're 1022 00:44:51,109 --> 00:44:49,040 studying and of course 1023 00:44:52,710 --> 00:44:51,119 the cold adam lab when i got there i 1024 00:44:54,069 --> 00:44:52,720 made my buddy get out the camera and 1025 00:44:55,510 --> 00:44:54,079 take pictures of me because at that 1026 00:44:57,430 --> 00:44:55,520 point i didn't even know if i was going 1027 00:44:59,030 --> 00:44:57,440 to get to work on it or not i was just 1028 00:45:01,670 --> 00:44:59,040 excited to see the label on the outside 1029 00:45:05,990 --> 00:45:03,750 and this is a really neat experiment 1030 00:45:09,190 --> 00:45:06,000 where we were actually doing biological 1031 00:45:11,109 --> 00:45:09,200 printing so a experiment that again 1032 00:45:12,550 --> 00:45:11,119 utilizes that microgravity environment 1033 00:45:15,030 --> 00:45:12,560 to build up 1034 00:45:17,270 --> 00:45:15,040 3d models of what we hope one day could 1035 00:45:19,589 --> 00:45:17,280 be actual organs and there i am getting 1036 00:45:21,510 --> 00:45:19,599 started on cold adam lab one day 1037 00:45:24,630 --> 00:45:21,520 combustion experiments flame sperm 1038 00:45:26,710 --> 00:45:24,640 spherical in space um everything you can 1039 00:45:27,750 --> 00:45:26,720 imagine and i think the last sequence 1040 00:45:29,430 --> 00:45:27,760 here 1041 00:45:30,309 --> 00:45:29,440 oh this is actually a great sequence 1042 00:45:31,510 --> 00:45:30,319 where 1043 00:45:34,069 --> 00:45:31,520 it shows 1044 00:45:35,589 --> 00:45:34,079 someone had noticed from the ground with 1045 00:45:38,550 --> 00:45:35,599 the over-the-shoulder video that i had 1046 00:45:41,349 --> 00:45:38,560 forgot to cap um one of their cell 1047 00:45:43,910 --> 00:45:41,359 cultures and it was just again another 1048 00:45:47,109 --> 00:45:43,920 example of how fun it is to to have that 1049 00:45:51,030 --> 00:45:47,119 team work with people on the ground 1050 00:45:54,069 --> 00:45:51,040 automated tech demonstration experiments 1051 00:45:56,390 --> 00:45:54,079 and a lot of how cellular organisms 1052 00:45:57,750 --> 00:45:56,400 react to the microgravity environment a 1053 00:45:59,990 --> 00:45:57,760 lot of people ask me what kind of 1054 00:46:03,109 --> 00:46:00,000 science do you do on iss and i say it's 1055 00:46:04,950 --> 00:46:03,119 it's not one kind it's just the kind 1056 00:46:07,109 --> 00:46:04,960 that you can't do anywhere else and 1057 00:46:14,230 --> 00:46:07,119 anything that qualifies we do it up 1058 00:46:19,109 --> 00:46:17,030 so um since we're in the nest and this 1059 00:46:21,510 --> 00:46:19,119 is a small group i thought i'd share 1060 00:46:23,670 --> 00:46:21,520 that this picture that is one that i 1061 00:46:26,550 --> 00:46:23,680 love so much actually was not as easy to 1062 00:46:28,309 --> 00:46:26,560 take as it might appear there it's not 1063 00:46:30,470 --> 00:46:28,319 very easy to pose for pictures in 1064 00:46:32,630 --> 00:46:30,480 microgravity 1065 00:46:34,309 --> 00:46:32,640 especially when you're carrying a 1066 00:46:37,030 --> 00:46:34,319 multi-pound 1067 00:46:39,910 --> 00:46:37,040 object with you and so 1068 00:46:43,670 --> 00:46:41,829 it didn't actually go as easily as it 1069 00:46:44,710 --> 00:46:43,680 appeared in that other picture but we we 1070 00:46:47,270 --> 00:46:44,720 had fun 1071 00:46:48,790 --> 00:46:47,280 and working on the experiment whether 1072 00:46:50,470 --> 00:46:48,800 that be in front of it or from the 1073 00:46:53,109 --> 00:46:50,480 ceiling 1074 00:46:54,790 --> 00:46:53,119 and um i was not working this fast i 1075 00:46:56,550 --> 00:46:54,800 appreciate kamal mentioning that i 1076 00:46:58,790 --> 00:46:56,560 apparently did work quickly this is a 1077 00:47:00,150 --> 00:46:58,800 sped up video of some things and 1078 00:47:01,430 --> 00:47:00,160 actually i need to go back because i 1079 00:47:02,790 --> 00:47:01,440 missed the one thing i wanted to show 1080 00:47:04,390 --> 00:47:02,800 you so just going to narrate a little 1081 00:47:06,230 --> 00:47:04,400 bit like the real life side of what's 1082 00:47:07,589 --> 00:47:06,240 going on here so this 1083 00:47:09,750 --> 00:47:07,599 this thing over here is actually our 1084 00:47:12,390 --> 00:47:09,760 exercise bike and you'll see there's a 1085 00:47:14,870 --> 00:47:12,400 hand that pops on someone was actually 1086 00:47:17,109 --> 00:47:14,880 exercising on the exercise bike right 1087 00:47:18,550 --> 00:47:17,119 next to me while i was doing a lot of 1088 00:47:20,470 --> 00:47:18,560 this work 1089 00:47:22,790 --> 00:47:20,480 i put this one up i hope i'm not causing 1090 00:47:24,710 --> 00:47:22,800 anyone any consternation in the in the 1091 00:47:26,470 --> 00:47:24,720 cold adam lab team because i can only 1092 00:47:28,710 --> 00:47:26,480 imagine what was going through their 1093 00:47:30,630 --> 00:47:28,720 mind when they saw some stranger um with 1094 00:47:33,270 --> 00:47:30,640 their hands inside of their very very 1095 00:47:35,030 --> 00:47:33,280 delicate instrument and um and working 1096 00:47:37,750 --> 00:47:35,040 in the minutia but they did such an 1097 00:47:39,750 --> 00:47:37,760 awesome job of training me they actually 1098 00:47:41,750 --> 00:47:39,760 scheduled time for me to learn how to 1099 00:47:44,950 --> 00:47:41,760 use all of these new tools with lasers 1100 00:47:46,950 --> 00:47:44,960 and the fiber optics um there i am so 1101 00:47:48,630 --> 00:47:46,960 this you you notice i went off camera 1102 00:47:50,950 --> 00:47:48,640 for a second while i'm talking to jim 1103 00:47:52,390 --> 00:47:50,960 and that was the uh space equivalent of 1104 00:47:54,230 --> 00:47:52,400 being on mute 1105 00:47:57,030 --> 00:47:54,240 because i tried to talk to him with our 1106 00:47:59,270 --> 00:47:57,040 audio unit not turned on there so that 1107 00:48:03,829 --> 00:47:59,280 just shows you that that i started that 1108 00:48:07,589 --> 00:48:04,829 and 1109 00:48:09,030 --> 00:48:07,599 um i just did a little day in the life i 1110 00:48:12,069 --> 00:48:09,040 really enjoyed going back through these 1111 00:48:13,910 --> 00:48:12,079 videos to prepare for today 1112 00:48:15,270 --> 00:48:13,920 and i wanted to also thank you all i 1113 00:48:17,670 --> 00:48:15,280 don't know if you heard about this was 1114 00:48:20,069 --> 00:48:17,680 the first all-female replacement of a 1115 00:48:22,630 --> 00:48:20,079 science module on a cold atom lab that 1116 00:48:25,589 --> 00:48:22,640 was also done during my mission and 1117 00:48:27,030 --> 00:48:25,599 obviously just a joke but um there was 1118 00:48:28,549 --> 00:48:27,040 there was an opportunity that i got to 1119 00:48:30,710 --> 00:48:28,559 work with jessica on this so that's 1120 00:48:32,470 --> 00:48:30,720 always fun 1121 00:48:34,309 --> 00:48:32,480 but we don't only work on board the 1122 00:48:35,750 --> 00:48:34,319 space station yes we have some time off 1123 00:48:37,750 --> 00:48:35,760 one of my favorite things to do in my 1124 00:48:39,109 --> 00:48:37,760 time off was to be in the cupola window 1125 00:48:40,230 --> 00:48:39,119 looking down on earth and taking 1126 00:48:43,030 --> 00:48:40,240 pictures 1127 00:48:44,950 --> 00:48:43,040 and including one of 1128 00:48:46,630 --> 00:48:44,960 you all 1129 00:48:48,710 --> 00:48:46,640 oh the circle didn't show up but there 1130 00:48:51,190 --> 00:48:48,720 was a circle around you guys or did it 1131 00:48:53,750 --> 00:48:51,200 show up okay thank you um but my 1132 00:48:56,470 --> 00:48:53,760 favorite night photography i i obviously 1133 00:48:57,829 --> 00:48:56,480 really enjoy this and looking down on 1134 00:48:59,349 --> 00:48:57,839 those cold regions that have the 1135 00:49:02,710 --> 00:48:59,359 northern lights and southern lights from 1136 00:49:05,670 --> 00:49:02,720 up there was really special for me 1137 00:49:07,349 --> 00:49:05,680 this is my video this is just us having 1138 00:49:08,790 --> 00:49:07,359 a little bit of fun that's me and nick 1139 00:49:10,710 --> 00:49:08,800 hague and you can see drew morgan 1140 00:49:13,430 --> 00:49:10,720 actually exercising in the background 1141 00:49:15,750 --> 00:49:13,440 but this is in my mind what's happening 1142 00:49:17,190 --> 00:49:15,760 inside cold adam lab 1143 00:49:19,270 --> 00:49:17,200 there's a blob 1144 00:49:21,270 --> 00:49:19,280 and thanks to being in space we can 1145 00:49:24,309 --> 00:49:21,280 maintain that blob a little longer than 1146 00:49:26,630 --> 00:49:24,319 we can maintain blobs on earth and you 1147 00:49:28,870 --> 00:49:26,640 know there's like we talk about no 1148 00:49:32,069 --> 00:49:28,880 asymmetric interaction with boundary 1149 00:49:34,870 --> 00:49:32,079 conditions and a longer longer lifetime 1150 00:49:37,589 --> 00:49:34,880 so so i i wanted to offer that up as a 1151 00:49:40,230 --> 00:49:37,599 little explanation 1152 00:49:41,430 --> 00:49:40,240 of course no no recreational time is 1153 00:49:43,270 --> 00:49:41,440 complete without dinner with your 1154 00:49:45,589 --> 00:49:43,280 buddies and that was another fun way 1155 00:49:47,270 --> 00:49:45,599 that we we bonded as a crew 1156 00:49:50,549 --> 00:49:47,280 of course all good things must come to 1157 00:49:52,470 --> 00:49:50,559 an end and eventually after 328 days uh 1158 00:49:55,109 --> 00:49:52,480 the day that i did the upgrade on cal 1159 00:49:57,270 --> 00:49:55,119 was like day 320 believe it or not i 1160 00:49:58,390 --> 00:49:57,280 slipped it right in before i got to come 1161 00:49:59,589 --> 00:49:58,400 home 1162 00:50:04,630 --> 00:49:59,599 and 1163 00:50:07,270 --> 00:50:04,640 extracted from the spacecraft 1164 00:50:08,630 --> 00:50:07,280 and actually 24 hours later being back 1165 00:50:11,589 --> 00:50:08,640 in houston 1166 00:50:16,069 --> 00:50:11,599 this is me thinking i did it i worked on 1167 00:50:19,829 --> 00:50:18,230 and of course we are at a really 1168 00:50:21,270 --> 00:50:19,839 exciting time now what's next for 1169 00:50:23,190 --> 00:50:21,280 astronauts and this is where the 1170 00:50:24,790 --> 00:50:23,200 partnership between the human space 1171 00:50:26,950 --> 00:50:24,800 flight at johnson space center and what 1172 00:50:28,549 --> 00:50:26,960 you all do here at jpl is so important 1173 00:50:30,069 --> 00:50:28,559 because we are going back to the moon 1174 00:50:32,309 --> 00:50:30,079 we're going to be partnering the 1175 00:50:35,030 --> 00:50:32,319 robotics and the humans together 1176 00:50:37,030 --> 00:50:35,040 obviously can do more than than what any 1177 00:50:39,589 --> 00:50:37,040 of us can do alone and i think cold adam 1178 00:50:40,790 --> 00:50:39,599 labs collaboration showed that as well 1179 00:50:43,589 --> 00:50:40,800 as the future work that we're going to 1180 00:50:45,109 --> 00:50:43,599 do so we can't wait and at johnson space 1181 00:50:47,430 --> 00:50:45,119 center to keep working with you all as 1182 00:50:49,349 --> 00:50:47,440 you all explore other bodies and we're a 1183 00:50:56,630 --> 00:50:49,359 part of it 1184 00:51:01,829 --> 00:50:59,030 thank you christina yes i want to say 1185 00:51:04,230 --> 00:51:01,839 something yeah so the science module 1186 00:51:06,069 --> 00:51:04,240 that you replaced uh 1187 00:51:09,190 --> 00:51:06,079 we brought it back 1188 00:51:12,150 --> 00:51:09,200 to earth and he has found a home at the 1189 00:51:13,270 --> 00:51:12,160 smithsonian museum so it will be given 1190 00:51:15,109 --> 00:51:13,280 to them 1191 00:51:16,950 --> 00:51:15,119 soon so we just want to make this 1192 00:51:28,069 --> 00:51:16,960 announcement and let you know so thank 1193 00:51:31,990 --> 00:51:29,670 okay thank you 1194 00:51:34,390 --> 00:51:32,000 i'm jason williams i am the project 1195 00:51:37,349 --> 00:51:34,400 scientist for the cold adam lab and 1196 00:51:39,589 --> 00:51:37,359 i have the distinction to introduce uh 1197 00:51:41,990 --> 00:51:39,599 professor nobel laureate eric cornell in 1198 00:51:43,349 --> 00:51:42,000 just a few minutes but um i wanted to 1199 00:51:47,030 --> 00:51:43,359 take a minute to talk to you about the 1200 00:51:49,349 --> 00:51:47,040 science that that we and the the 1201 00:51:52,630 --> 00:51:49,359 distinguished and very helpful uh pi 1202 00:51:54,390 --> 00:51:52,640 team have been doing and 1203 00:51:56,470 --> 00:51:54,400 so 1204 00:51:58,790 --> 00:51:56,480 cold adam lab has been operating for 1205 00:52:00,870 --> 00:51:58,800 four years and it has been an exciting 1206 00:52:02,710 --> 00:52:00,880 four years i'll tell you that i see 1207 00:52:05,030 --> 00:52:02,720 i see a lot of 1208 00:52:07,430 --> 00:52:05,040 some of the members of the cold adam lab 1209 00:52:10,150 --> 00:52:07,440 team that are here it's it's been 1210 00:52:12,790 --> 00:52:10,160 uh a uh 1211 00:52:15,349 --> 00:52:12,800 a big effort a fulfilling effort for 1212 00:52:17,430 --> 00:52:15,359 many of us and uh not only scientists 1213 00:52:20,069 --> 00:52:17,440 engineers 1214 00:52:22,470 --> 00:52:20,079 team students it's it's been i've never 1215 00:52:23,430 --> 00:52:22,480 worked with a greater group of people um 1216 00:52:26,230 --> 00:52:23,440 and 1217 00:52:27,990 --> 00:52:26,240 uh astronaut uh christina koch was 1218 00:52:30,630 --> 00:52:28,000 talking about um 1219 00:52:32,790 --> 00:52:30,640 doing some of the work that on cold adam 1220 00:52:34,390 --> 00:52:32,800 lab replacing it we got the chance to 1221 00:52:36,390 --> 00:52:34,400 watch this from the ground it was 1222 00:52:37,829 --> 00:52:36,400 exciting also one of the scariest 1223 00:52:40,390 --> 00:52:37,839 moments of my life 1224 00:52:42,069 --> 00:52:40,400 but she did an amazing job because as 1225 00:52:44,630 --> 00:52:42,079 you'll see we've gotten some some really 1226 00:52:46,710 --> 00:52:44,640 great science out so 1227 00:52:48,069 --> 00:52:46,720 as kamal had mentioned we've operated 1228 00:52:51,190 --> 00:52:48,079 for four years 1229 00:52:52,870 --> 00:52:51,200 we also have collected uh 1230 00:52:55,349 --> 00:52:52,880 tens of thousands of experimental runs 1231 00:52:57,349 --> 00:52:55,359 for the the pi teams and so this is 1232 00:52:58,950 --> 00:52:57,359 absolutely the most bizarre einstein 1233 00:53:01,190 --> 00:52:58,960 condensates that have been produced in 1234 00:53:04,069 --> 00:53:01,200 earth this has actually been 1235 00:53:06,549 --> 00:53:04,079 demonstrated as uh the first multi-user 1236 00:53:09,109 --> 00:53:06,559 facility for quantum gas research on 1237 00:53:11,670 --> 00:53:09,119 in space and it has really fulfilled its 1238 00:53:15,030 --> 00:53:11,680 promise going above and beyond uh the 1239 00:53:17,190 --> 00:53:15,040 initial um mission lifetime 1240 00:53:19,270 --> 00:53:17,200 we chew chief bose-einstein condensates 1241 00:53:21,990 --> 00:53:19,280 in space in fact we produce them every 1242 00:53:23,750 --> 00:53:22,000 day as part of our startup and 1243 00:53:25,910 --> 00:53:23,760 and 1244 00:53:28,390 --> 00:53:25,920 we can now 1245 00:53:30,710 --> 00:53:28,400 not only do experiments with rubidium so 1246 00:53:33,190 --> 00:53:30,720 a single atomic species but we can 1247 00:53:37,670 --> 00:53:35,109 dual atomic species both einstein 1248 00:53:39,030 --> 00:53:37,680 condensates rubidium and potassium these 1249 00:53:41,270 --> 00:53:39,040 are different very different atomic 1250 00:53:43,109 --> 00:53:41,280 species they have different masses 1251 00:53:45,670 --> 00:53:43,119 completely different properties and we 1252 00:53:47,589 --> 00:53:45,680 can also produce those at the same time 1253 00:53:49,829 --> 00:53:47,599 and manipulate them in space allow them 1254 00:53:52,309 --> 00:53:49,839 to interact and 1255 00:53:54,230 --> 00:53:52,319 flushes out another very large body of 1256 00:53:56,630 --> 00:53:54,240 physics that has been opened up for the 1257 00:53:59,510 --> 00:53:56,640 first time in space studying interacting 1258 00:54:02,870 --> 00:53:59,520 now ultra cold quantum gases 1259 00:54:05,430 --> 00:54:02,880 we've also as part of the commissioning 1260 00:54:08,390 --> 00:54:05,440 seen atoms just floating in space and 1261 00:54:09,270 --> 00:54:08,400 free fall for seconds time scales which 1262 00:54:14,390 --> 00:54:09,280 is 1263 00:54:16,549 --> 00:54:14,400 um 1264 00:54:18,710 --> 00:54:16,559 as also uh kamal had mentioned we've 1265 00:54:20,230 --> 00:54:18,720 achieved unprecedented cooling to sub 1266 00:54:22,870 --> 00:54:20,240 sub nano kelvin temperatures even down 1267 00:54:25,829 --> 00:54:22,880 to the 52 pico kelvin regime so 1268 00:54:28,630 --> 00:54:25,839 uh this this picture i really 1269 00:54:30,630 --> 00:54:28,640 enjoy of uh astronaut 1270 00:54:33,349 --> 00:54:30,640 finding a bose einstein condensate in 1271 00:54:35,109 --> 00:54:33,359 space and observing its properties uh in 1272 00:54:36,870 --> 00:54:35,119 many ways that's that's what we're doing 1273 00:54:39,349 --> 00:54:36,880 though we're releasing these atoms in 1274 00:54:41,190 --> 00:54:39,359 space we actually take pictures of them 1275 00:54:43,349 --> 00:54:41,200 as part of our 1276 00:54:47,030 --> 00:54:43,359 our data return and we're seeing what 1277 00:54:48,230 --> 00:54:47,040 they do we see their unique properties 1278 00:54:49,510 --> 00:54:48,240 so 1279 00:54:51,589 --> 00:54:49,520 um 1280 00:54:52,950 --> 00:54:51,599 okay so uh 1281 00:54:54,150 --> 00:54:52,960 i wanted to take a few minutes to talk 1282 00:54:55,910 --> 00:54:54,160 about the pi teams because they're 1283 00:54:58,549 --> 00:54:55,920 really the heart of what we're doing in 1284 00:55:00,789 --> 00:54:58,559 cold adam lab there were five 1285 00:55:03,910 --> 00:55:00,799 flight pi teams that were chosen for the 1286 00:55:05,589 --> 00:55:03,920 initial cal nra and these are really 1287 00:55:07,430 --> 00:55:05,599 pathfinders no one's ever done 1288 00:55:09,109 --> 00:55:07,440 experiments like these five pi's have 1289 00:55:10,470 --> 00:55:09,119 done before 1290 00:55:13,670 --> 00:55:10,480 and so 1291 00:55:15,430 --> 00:55:13,680 for example uh nathan lemblet 1292 00:55:19,589 --> 00:55:15,440 has been doing some experiments 1293 00:55:21,990 --> 00:55:19,599 observing ultracold gases in bubble 1294 00:55:24,150 --> 00:55:22,000 geometries in space and so how does the 1295 00:55:25,510 --> 00:55:24,160 quantum gas with wave-like nature 1296 00:55:28,230 --> 00:55:25,520 perform when it's in this unique 1297 00:55:30,309 --> 00:55:28,240 topology of a bubble or a shell these 1298 00:55:32,549 --> 00:55:30,319 are experiments that are beginning and 1299 00:55:33,750 --> 00:55:32,559 have been progressing well for nathan 1300 00:55:36,870 --> 00:55:33,760 lundblad 1301 00:55:39,349 --> 00:55:36,880 the team by nick bigelow 1302 00:55:41,030 --> 00:55:39,359 he leads a consortium that includes 1303 00:55:42,950 --> 00:55:41,040 nobel laureates wolfgang ketterly and 1304 00:55:47,190 --> 00:55:42,960 bill phillips and his team is really 1305 00:55:49,109 --> 00:55:47,200 exploring okay i have two atomic species 1306 00:55:50,950 --> 00:55:49,119 if i perform adam interferometry on it 1307 00:55:53,109 --> 00:55:50,960 which i will explain a little bit more 1308 00:55:55,829 --> 00:55:53,119 in a few minutes this can be a very 1309 00:55:58,150 --> 00:55:55,839 precise uh sensor for gravity so how can 1310 00:56:00,870 --> 00:55:58,160 we take cal where it is mature the 1311 00:56:03,510 --> 00:56:00,880 technology so that someday we can 1312 00:56:05,589 --> 00:56:03,520 perform dual species adam interferometry 1313 00:56:08,230 --> 00:56:05,599 and try to test some of einstein's 1314 00:56:10,630 --> 00:56:08,240 theories such as the universality of 1315 00:56:12,870 --> 00:56:10,640 free fall or do these quantum objects 1316 00:56:14,710 --> 00:56:12,880 fall the same in gravity we know they do 1317 00:56:18,230 --> 00:56:14,720 but to what level do they really fall at 1318 00:56:21,190 --> 00:56:18,240 the same rates in gravity and 1319 00:56:23,750 --> 00:56:21,200 the group of um 1320 00:56:26,549 --> 00:56:23,760 of eric cornell uh you'll hear a little 1321 00:56:28,230 --> 00:56:26,559 bit of his talk uh of what he's doing 1322 00:56:30,390 --> 00:56:28,240 but his group is 1323 00:56:32,549 --> 00:56:30,400 along with peter ingalls is studying the 1324 00:56:35,270 --> 00:56:32,559 quantum three body problem which is a 1325 00:56:37,030 --> 00:56:35,280 very difficult problem to study but it 1326 00:56:39,109 --> 00:56:37,040 has universal properties that can be 1327 00:56:40,789 --> 00:56:39,119 extended to other systems 1328 00:56:42,069 --> 00:56:40,799 sort of analogous to feynman's quantum 1329 00:56:44,549 --> 00:56:42,079 simulator 1330 00:56:46,470 --> 00:56:44,559 we can take atoms as quantum systems we 1331 00:56:47,750 --> 00:56:46,480 can simulate their properties now how 1332 00:56:50,390 --> 00:56:47,760 does that extend to the rest of the 1333 00:56:51,829 --> 00:56:50,400 quantum world perhaps like nuclei and 1334 00:56:55,190 --> 00:56:51,839 molecules and other things that are much 1335 00:56:56,870 --> 00:56:55,200 much more difficult to study 1336 00:57:00,630 --> 00:56:56,880 cass sackett's group is studying 1337 00:57:03,349 --> 00:57:00,640 adiabatic cooling in space a lot of his 1338 00:57:04,549 --> 00:57:03,359 initial efforts are how cold can we make 1339 00:57:07,109 --> 00:57:04,559 things if you 1340 00:57:10,470 --> 00:57:07,119 have space have a uniform environment 1341 00:57:12,390 --> 00:57:10,480 and you relax the confinement and 1342 00:57:14,069 --> 00:57:12,400 so-called adiabatic cooling but make 1343 00:57:15,349 --> 00:57:14,079 extremely weak traps your atoms are 1344 00:57:17,349 --> 00:57:15,359 going to get really cold and really 1345 00:57:19,270 --> 00:57:17,359 trying to push the limits of how 1346 00:57:22,230 --> 00:57:19,280 how well we can 1347 00:57:24,870 --> 00:57:22,240 prepare ultracold gases in space 1348 00:57:27,190 --> 00:57:24,880 and then my team is studying um 1349 00:57:29,829 --> 00:57:27,200 fetchbox molecules these unique type of 1350 00:57:31,829 --> 00:57:29,839 molecules with quantum gases uh it's 1351 00:57:34,230 --> 00:57:31,839 it's sort of a form of quantum chemistry 1352 00:57:36,230 --> 00:57:34,240 how can we form these molecules and how 1353 00:57:37,349 --> 00:57:36,240 can these be used as a very precise 1354 00:57:39,510 --> 00:57:37,359 source for 1355 00:57:41,109 --> 00:57:39,520 uh precision measurement in the in the 1356 00:57:44,630 --> 00:57:41,119 future 1357 00:57:46,789 --> 00:57:44,640 and so this is uh these are um initial 1358 00:57:49,109 --> 00:57:46,799 experiments uh that 1359 00:57:50,789 --> 00:57:49,119 have popped up these are all our space 1360 00:57:53,109 --> 00:57:50,799 enabled um 1361 00:57:55,510 --> 00:57:53,119 and we've been getting some some very 1362 00:57:57,990 --> 00:57:55,520 impressive results 1363 00:57:59,349 --> 00:57:58,000 to zoom in a bit more since the 1364 00:58:02,230 --> 00:57:59,359 upgrade 1365 00:58:03,349 --> 00:58:02,240 by astronaut coke we've this brought to 1366 00:58:07,109 --> 00:58:03,359 us the capability for atom 1367 00:58:09,430 --> 00:58:07,119 interferometry and adam interferometry 1368 00:58:11,789 --> 00:58:09,440 says okay we know that atoms are waves 1369 00:58:14,710 --> 00:58:11,799 we've known that since the 1370 00:58:16,069 --> 00:58:14,720 1920s it's one of the basics of quantum 1371 00:58:18,069 --> 00:58:16,079 mechanics 1372 00:58:20,630 --> 00:58:18,079 using some more recent technologies that 1373 00:58:23,270 --> 00:58:20,640 have been developed to use laser pulses 1374 00:58:25,270 --> 00:58:23,280 you can use a laser pulse and split two 1375 00:58:27,349 --> 00:58:25,280 wave atom waves apart 1376 00:58:28,470 --> 00:58:27,359 and allow it to recombine and interfere 1377 00:58:30,549 --> 00:58:28,480 with itself 1378 00:58:32,950 --> 00:58:30,559 and you make an atom interferometer out 1379 00:58:34,630 --> 00:58:32,960 of matter waves 1380 00:58:37,510 --> 00:58:34,640 this uh 1381 00:58:40,870 --> 00:58:37,520 this is a technology that is uh 1382 00:58:42,789 --> 00:58:40,880 developed on birth on earth it uh 1383 00:58:45,750 --> 00:58:42,799 has a lot of promise and space because 1384 00:58:47,589 --> 00:58:45,760 in space you uh don't need to drop your 1385 00:58:49,109 --> 00:58:47,599 atoms and allow them to drop a long 1386 00:58:52,230 --> 00:58:49,119 distance you release them and your atoms 1387 00:58:55,990 --> 00:58:52,240 float in free fall and we have 1388 00:58:58,549 --> 00:58:56,000 some very uh cutting edge result results 1389 00:59:01,190 --> 00:58:58,559 we've demonstrated for the first time 1390 00:59:03,430 --> 00:59:01,200 a dual species atom interferometer where 1391 00:59:05,270 --> 00:59:03,440 single laser pulse 1392 00:59:07,670 --> 00:59:05,280 creates two atom interferometers and we 1393 00:59:10,069 --> 00:59:07,680 see how gravity at a very low level acts 1394 00:59:12,309 --> 00:59:10,079 on potassium and rubidium and this is a 1395 00:59:13,829 --> 00:59:12,319 basis for for experiments that are going 1396 00:59:16,230 --> 00:59:13,839 on but first time that this has been 1397 00:59:18,789 --> 00:59:16,240 demonstrated in space and this as i 1398 00:59:21,030 --> 00:59:18,799 mentioned will form the basis of 1399 00:59:22,390 --> 00:59:21,040 eventually maturing the technology to 1400 00:59:24,230 --> 00:59:22,400 look for 1401 00:59:25,910 --> 00:59:24,240 violations of the equivalence principle 1402 00:59:27,510 --> 00:59:25,920 and this is one of the great tools that 1403 00:59:28,630 --> 00:59:27,520 has promised for searching for new 1404 00:59:30,870 --> 00:59:28,640 physics 1405 00:59:32,870 --> 00:59:30,880 in the future 1406 00:59:35,510 --> 00:59:32,880 so with that 1407 00:59:37,829 --> 00:59:35,520 i would like to introduce 1408 00:59:40,789 --> 00:59:37,839 a professor and nobel laureate eric 1409 00:59:40,799 --> 00:59:45,510 thank you 1410 00:59:52,789 --> 00:59:49,349 so eric is a um 1411 00:59:54,789 --> 00:59:52,799 a fellow of nistangila uh a adjoint 1412 00:59:56,630 --> 00:59:54,799 professor at the university of calr 1413 00:59:58,470 --> 00:59:56,640 colorado in boulder 1414 01:00:00,630 --> 00:59:58,480 he has a very long resume i had a hard 1415 01:00:02,870 --> 01:00:00,640 time distilling it down but 1416 01:00:04,309 --> 01:00:02,880 his current research includes uh 1417 01:00:06,309 --> 01:00:04,319 searches for the electric dip a 1418 01:00:08,470 --> 01:00:06,319 permanent electric dipole moment some 1419 01:00:11,670 --> 01:00:08,480 studies of strongly interacting 1420 01:00:15,589 --> 01:00:11,680 gases and the fu body problem he's a 1421 01:00:17,990 --> 01:00:15,599 pete one of the first pis on cal and 1422 01:00:19,589 --> 01:00:18,000 he also has a a very distinguished 1423 01:00:22,309 --> 01:00:19,599 awards record 1424 01:00:23,349 --> 01:00:22,319 received the presidential early career

science and in 2001 he received the 1429 01:00:34,309 --> 01:00:32,160 nobel prize along with wolfgang ketterly 1430 01:00:35,829 --> 01:00:34,319 and carl weinman for 1431 01:00:39,270 --> 01:00:35,839 first demonstration of bose einstein 1432 01:00:41,109 --> 01:00:39,280 condensation in a dilute gas so 1433 01:00:44,390 --> 01:00:41,119 we wanted to 1434 01:00:47,349 --> 01:00:44,400 present this award to him 1435 01:00:51,270 --> 01:00:47,359 and so i will again let allow 1436 01:01:07,750 --> 01:00:51,280 uh kr2 to present it but this is for in 1437 01:01:13,510 --> 01:01:11,349 recognition of his leadership in 1438 01:01:21,510 --> 01:01:13,520 support of the advance of cold adam 1439 01:01:25,270 --> 01:01:23,270 and thank you jason it's always really a 1440 01:01:27,270 --> 01:01:25,280 lot of fun for me to come to jpl this is 1441 01:01:28,870 --> 01:01:27,280 the fourth anniversary of cal and space 1442 01:01:30,950 --> 01:01:28,880 but i've been involved one way or 1443 01:01:32,630 --> 01:01:30,960 another in the program for eight years 1444 01:01:33,910 --> 01:01:32,640 going on a decade and it's been so 1445 01:01:36,150 --> 01:01:33,920 exciting for me 1446 01:01:38,390 --> 01:01:36,160 uh if i had on if i had only a single 1447 01:01:42,230 --> 01:01:38,400 gripe it would be that somehow at cal 1448 01:01:44,150 --> 01:01:42,240 events i often end up speaking after uh 1449 01:01:45,829 --> 01:01:44,160 jason and christina and i always feel a 1450 01:01:48,630 --> 01:01:45,839 little bit not quite as polished but i'm 1451 01:01:53,510 --> 01:01:50,470 i'm here to talk about 1452 01:01:54,549 --> 01:01:53,520 people have alluded before to quantum in 1453 01:01:57,029 --> 01:01:54,559 space 1454 01:01:59,349 --> 01:01:57,039 and uh that's the topic of my in my uh 1455 01:02:01,029 --> 01:01:59,359 talk today 1456 01:02:03,510 --> 01:02:01,039 before we can talk about quantum and 1457 01:02:06,630 --> 01:02:03,520 space i want to talk about uh ultra cold 1458 01:02:07,750 --> 01:02:06,640 ultra cold in space 1459 01:02:09,990 --> 01:02:07,760 and uh 1460 01:02:11,990 --> 01:02:10,000 vi and and sort of tie that into a word 1461 01:02:14,150 --> 01:02:12,000 we've already heard before which is bose 1462 01:02:15,670 --> 01:02:14,160 einstein conversation and space space 1463 01:02:17,910 --> 01:02:15,680 space 1464 01:02:19,750 --> 01:02:17,920 i'll probably forget uh 1465 01:02:21,589 --> 01:02:19,760 you know when giving a sort of popular 1466 01:02:23,270 --> 01:02:21,599 level lecture when tries not to use 1467 01:02:25,990 --> 01:02:23,280 acronyms i'll probably forget and call 1468 01:02:28,230 --> 01:02:26,000 it bec but you're not really working at 1469 01:02:30,630 --> 01:02:28,240 nasa or jpl if you don't throw a lot of 1470 01:02:32,789 --> 01:02:30,640 around a lot of tlas and so i've got 1471 01:02:34,870 --> 01:02:32,799 into the habit myself bec bose einstein 1472 01:02:36,789 --> 01:02:34,880 condensation so i'm going to start with 1473 01:02:39,510 --> 01:02:36,799 the cold and just to put things in 1474 01:02:42,230 --> 01:02:39,520 context uh scientists engineers we 1475 01:02:42,950 --> 01:02:42,240 measure temperatures in absolute units 1476 01:02:51,589 --> 01:02:42,960 so 1477 01:02:53,349 --> 01:02:51,599 what we would call minus 460 fahrenheit 1478 01:02:55,270 --> 01:02:53,359 is what we would call absolute zero zero 1479 01:02:56,789 --> 01:02:55,280 degrees kelvin it can't ever get to zero 1480 01:02:59,190 --> 01:02:56,799 degrees kelvin but as we'll see you can 1481 01:03:00,630 --> 01:02:59,200 get awfully close 1482 01:03:02,390 --> 01:03:00,640 an important line which you can maybe 1483 01:03:04,630 --> 01:03:02,400 just barely see in the auditorium here 1484 01:03:06,230 --> 01:03:04,640 is just barely above that purple line is 1485 01:03:07,349 --> 01:03:06,240 the temperature of deep space three 1486 01:03:09,109 --> 01:03:07,359 kelvin 1487 01:03:12,630 --> 01:03:09,119 which is uh people have already alluded 1488 01:03:14,309 --> 01:03:12,640 to cold but yeah not really 1489 01:03:16,069 --> 01:03:14,319 we get a whole lot colder in fact we're 1490 01:03:18,470 --> 01:03:16,079 gonna the next slide we're gonna expand 1491 01:03:21,029 --> 01:03:18,480 out between that zero and three 1492 01:03:22,870 --> 01:03:21,039 and uh draw the analogy uh the three to 1493 01:03:25,510 --> 01:03:22,880 three degree temperature of deep space 1494 01:03:26,789 --> 01:03:25,520 is to mount everest as uh say the 1495 01:03:29,029 --> 01:03:26,799 thickness of a 1496 01:03:30,710 --> 01:03:29,039 100 nano kelvin the typical temperature 1497 01:03:32,789 --> 01:03:30,720 of both einstein condensation is to the 1498 01:03:35,750 --> 01:03:32,799 thickness of a pencil lead say a 1499 01:03:37,750 --> 01:03:35,760 millimeter so we're going down uh 1500 01:03:39,430 --> 01:03:37,760 you know whatever this works out to here 1501 01:03:41,349 --> 01:03:39,440 seven eight orders of magnitude down in 1502 01:03:43,589 --> 01:03:41,359 temperature from what already people 1503 01:03:45,670 --> 01:03:43,599 usually think of as a very cold place 1504 01:03:47,990 --> 01:03:45,680 why so cold what's the relevance in cold 1505 01:03:49,510 --> 01:03:48,000 and how does that connect us back to 1506 01:03:51,510 --> 01:03:49,520 the quantum mechanics and i will say 1507 01:03:53,510 --> 01:03:51,520 it's a little bit of a spoiler alert 1508 01:03:55,349 --> 01:03:53,520 this 100 nano kelvin which i'm making 1509 01:03:58,069 --> 01:03:55,359 such a big deal 100 billionths of a 1510 01:04:01,190 --> 01:03:58,079 degree above absolute zero cal gets a 1511 01:04:03,510 --> 01:04:01,200 whole lot colder than that 1512 01:04:05,829 --> 01:04:03,520 um i i don't have time 1513 01:04:07,349 --> 01:04:05,839 to talk about how we get so very very 1514 01:04:10,309 --> 01:04:07,359 cold people have already alluded to 1515 01:04:12,950 --> 01:04:10,319 lasers and indeed uh we use the the 1516 01:04:15,430 --> 01:04:12,960 pressure of lasers of photons bouncing 1517 01:04:17,670 --> 01:04:15,440 off of atoms think of throwing ping-pong 1518 01:04:19,029 --> 01:04:17,680 balls at at bowling balls and if you 1519 01:04:20,710 --> 01:04:19,039 throw enough ping-pong balls at bowling 1520 01:04:22,710 --> 01:04:20,720 balls you could slow down a bowling ball 1521 01:04:24,870 --> 01:04:22,720 if it happened to be rolling towards you 1522 01:04:26,630 --> 01:04:24,880 being going slower means being colder 1523 01:04:28,069 --> 01:04:26,640 that's laser cooling 1524 01:04:29,750 --> 01:04:28,079 and then 1525 01:04:32,230 --> 01:04:29,760 laser cooling is part of it and magnetic 1526 01:04:34,630 --> 01:04:32,240 trapping is part of it too both on on 1527 01:04:36,470 --> 01:04:34,640 earth and in space we have a strong 1528 01:04:38,470 --> 01:04:36,480 magnetic fields that keep the atoms 1529 01:04:40,390 --> 01:04:38,480 together in a little blob and we let the 1530 01:04:42,470 --> 01:04:40,400 hottest atoms fall out of the edges much 1531 01:04:44,710 --> 01:04:42,480 like a a cup of hot coffee lets the 1532 01:04:47,029 --> 01:04:44,720 steam flow out uh get the 1533 01:04:49,109 --> 01:04:47,039 cup of hot coffee you see the steam 1534 01:04:50,950 --> 01:04:49,119 coming out that represents the hottest 1535 01:04:52,549 --> 01:04:50,960 of the coffee molecules making a break 1536 01:04:54,470 --> 01:04:52,559 for it and taking away with them more 1537 01:04:56,309 --> 01:04:54,480 than their fair share of energy cooling 1538 01:04:58,230 --> 01:04:56,319 the remaining coffee off evaporative 1539 01:04:59,589 --> 01:04:58,240 cooling and a magnetic trap these two 1540 01:05:01,510 --> 01:04:59,599 techniques allow us to get the bose 1541 01:05:03,910 --> 01:05:01,520 einstein condensation here's some 1542 01:05:05,190 --> 01:05:03,920 picture from really a long long time ago 1543 01:05:07,670 --> 01:05:05,200 early pictures of bose einstein 1544 01:05:10,150 --> 01:05:07,680 condensation you'll see these 1545 01:05:11,829 --> 01:05:10,160 false color images multiple times you 1546 01:05:14,390 --> 01:05:11,839 already have seen them these just 1547 01:05:16,069 --> 01:05:14,400 represent density plots basically 1548 01:05:18,230 --> 01:05:16,079 you turn off the magnetic trap you let 1549 01:05:20,309 --> 01:05:18,240 the atoms fly apart for a little while 1550 01:05:22,950 --> 01:05:20,319 and if they're going relatively fast as 1551 01:05:24,470 --> 01:05:22,960 they would be at 400 nano kelvin they 1552 01:05:26,069 --> 01:05:24,480 spread out in both directions and when 1553 01:05:28,789 --> 01:05:26,079 we take a picture we turn these shadow 1554 01:05:30,789 --> 01:05:28,799 images into into these mountain like 1555 01:05:33,109 --> 01:05:30,799 pictures if they're quite a bit colder 1556 01:05:36,069 --> 01:05:33,119 say 50 nano kelvin then we see this 1557 01:05:37,910 --> 01:05:36,079 single shark-like shark fin dorsal fin 1558 01:05:40,789 --> 01:05:37,920 which is the bose einstein condensate 1559 01:05:42,390 --> 01:05:40,799 it's a single wave uh representing all 1560 01:05:43,990 --> 01:05:42,400 the atoms participating in a bose 1561 01:05:45,829 --> 01:05:44,000 einstein condensation here we're 1562 01:05:47,510 --> 01:05:45,839 somewhere in between imagine that you've 1563 01:05:48,950 --> 01:05:47,520 you your ice tray is only a little bit 1564 01:05:50,710 --> 01:05:48,960 frozen you've got some ice and some 1565 01:05:54,150 --> 01:05:50,720 water some condensate and some regular 1566 01:05:58,630 --> 01:05:55,589 this is the group that did this low 1567 01:06:01,029 --> 01:05:58,640 these uh 30 some years ago 1568 01:06:02,150 --> 01:06:01,039 these people all went to stockholm with 1569 01:06:04,630 --> 01:06:02,160 us 1570 01:06:06,789 --> 01:06:04,640 for the nobel celebrations 1571 01:06:09,029 --> 01:06:06,799 uh and uh i mentioned particularly 1572 01:06:11,109 --> 01:06:09,039 debbie jin who was one of the very first 1573 01:06:14,309 --> 01:06:11,119 uh cal pis and unfortunately is no 1574 01:06:16,710 --> 01:06:14,319 longer with us died tragically young 1575 01:06:19,109 --> 01:06:16,720 uh what is this connection between very 1576 01:06:21,349 --> 01:06:19,119 cold and between quantum 1577 01:06:22,950 --> 01:06:21,359 and what is quantum and again begin with 1578 01:06:24,390 --> 01:06:22,960 uh some of you it's been a little while 1579 01:06:25,750 --> 01:06:24,400 since you took your first course in 1580 01:06:28,230 --> 01:06:25,760 quantum mechanics and so i'll just 1581 01:06:29,750 --> 01:06:28,240 review it here in about a minute um 1582 01:06:31,750 --> 01:06:29,760 atoms like everything else you can think 1583 01:06:33,829 --> 01:06:31,760 of them as two ways either the classical 1584 01:06:35,029 --> 01:06:33,839 way like like pool balls you know 1585 01:06:36,789 --> 01:06:35,039 bouncing off each other and maybe 1586 01:06:38,390 --> 01:06:36,799 falling into a pocket or like little 1587 01:06:41,430 --> 01:06:38,400 quantum waves 1588 01:06:43,190 --> 01:06:41,440 as things get colder they get wavier 1589 01:06:45,670 --> 01:06:43,200 what is that about why is making things 1590 01:06:47,270 --> 01:06:45,680 get colder make them wavier and really 1591 01:06:48,870 --> 01:06:47,280 it comes back to 1592 01:06:49,990 --> 01:06:48,880 if you don't know anything about quantum 1593 01:06:51,670 --> 01:06:50,000 mechanics but you've just read a 1594 01:06:52,870 --> 01:06:51,680 scientific american article you might 1595 01:06:54,710 --> 01:06:52,880 have heard of the 1596 01:06:56,390 --> 01:06:54,720 heisenberg's uncertainty principle you 1597 01:06:59,270 --> 01:06:56,400 can't simultaneously know where 1598 01:07:01,990 --> 01:06:59,280 something is and how fast it's going 1599 01:07:04,230 --> 01:07:02,000 well as you get colder and colder 1600 01:07:05,990 --> 01:07:04,240 you know how fast it's going because 1601 01:07:07,589 --> 01:07:06,000 colder and colder corresponds to moving 1602 01:07:08,470 --> 01:07:07,599 slower and slower so you can say on 1603 01:07:10,390 --> 01:07:08,480 average 1604 01:07:11,510 --> 01:07:10,400 the atoms are not moving at all and i 1605 01:07:13,270 --> 01:07:11,520 can say that with more and more 1606 01:07:15,349 --> 01:07:13,280 precision as i make the atoms colder and 1607 01:07:18,069 --> 01:07:15,359 colder their velocity is closer and 1608 01:07:20,710 --> 01:07:18,079 closer to zero heisenberg says 1609 01:07:22,069 --> 01:07:20,720 sorry if you know that very well how 1610 01:07:23,349 --> 01:07:22,079 fast something is going you can't know 1611 01:07:25,349 --> 01:07:23,359 where it is very well and so these 1612 01:07:27,109 --> 01:07:25,359 things look more and more like fuzzy 1613 01:07:29,270 --> 01:07:27,119 balls it's basically a 1614 01:07:31,670 --> 01:07:29,280 or a wave like object and it's a result 1615 01:07:33,589 --> 01:07:31,680 of of the uncertainty principle and if 1616 01:07:35,109 --> 01:07:33,599 you get really really cold then waviness 1617 01:07:37,349 --> 01:07:35,119 triumphs and you get bose einstein 1618 01:07:39,029 --> 01:07:37,359 condensation here in southern 1619 01:07:45,670 --> 01:07:39,039 california we would call it the ultimate 1620 01:07:50,069 --> 01:07:47,270 how are they like waves a beautiful 1621 01:07:53,190 --> 01:07:50,079 experiment done by another cal pi both 1622 01:07:54,630 --> 01:07:53,200 gone ketterly he took and it and it 1623 01:07:56,150 --> 01:07:54,640 you know it 1624 01:07:57,430 --> 01:07:56,160 pains me to say this because for many 1625 01:07:58,950 --> 01:07:57,440 years he and i were like arch 1626 01:08:01,029 --> 01:07:58,960 competitors but these days were kind of 1627 01:08:03,190 --> 01:08:01,039 pals and he did he did this beautiful 1628 01:08:04,549 --> 01:08:03,200 experiment and he took two condensates 1629 01:08:06,150 --> 01:08:04,559 and sort of two separate little magnetic 1630 01:08:08,710 --> 01:08:06,160 wells he let them overflow with each 1631 01:08:10,789 --> 01:08:08,720 other and when they overflowed you he 1632 01:08:12,549 --> 01:08:10,799 saw these stripes basically these 1633 01:08:14,710 --> 01:08:12,559 stripes are destructive interference 1634 01:08:16,630 --> 01:08:14,720 between atoms we think of waves like you 1635 01:08:18,070 --> 01:08:16,640 see ocean waves patterns of ocean waves 1636 01:08:19,349 --> 01:08:18,080 they can interfere constructively or 1637 01:08:20,950 --> 01:08:19,359 destructively 1638 01:08:22,789 --> 01:08:20,960 uh true for light you know you can get 1639 01:08:23,990 --> 01:08:22,799 laser wave lasers interfering with each 1640 01:08:24,950 --> 01:08:24,000 other and you get these interference 1641 01:08:26,870 --> 01:08:24,960 fringes 1642 01:08:28,789 --> 01:08:26,880 i find it still strange to imagine you 1643 01:08:30,070 --> 01:08:28,799 can take atoms plus atoms add them 1644 01:08:31,749 --> 01:08:30,080 together and get these sort of white 1645 01:08:34,550 --> 01:08:31,759 stripes which correspond to like no 1646 01:08:36,309 --> 01:08:34,560 atoms basically one set of atoms cancels 1647 01:08:38,709 --> 01:08:36,319 out the other atoms and this is 1648 01:08:40,390 --> 01:08:38,719 interference a common thing and things 1649 01:08:41,990 --> 01:08:40,400 which are waves and now we can see very 1650 01:08:44,950 --> 01:08:42,000 directly in these pictures that atoms 1651 01:08:47,030 --> 01:08:44,960 are waves these these so-called fringes 1652 01:08:49,110 --> 01:08:47,040 these interference patterns are 1653 01:08:51,269 --> 01:08:49,120 extremely sensitive 1654 01:08:53,910 --> 01:08:51,279 and they are sensitive to things like 1655 01:08:56,149 --> 01:08:53,920 acceleration and exotic new physics 1656 01:08:58,470 --> 01:08:56,159 of there's a proposal out to use things 1657 01:09:00,309 --> 01:08:58,480 like this to detect exotic new physics 1658 01:09:02,309 --> 01:09:00,319 including the gravity coming from things 1659 01:09:04,630 --> 01:09:02,319 you can't otherwise see 1660 01:09:06,709 --> 01:09:04,640 where do we hear about that dark matter 1661 01:09:08,229 --> 01:09:06,719 right so these are 1662 01:09:10,630 --> 01:09:08,239 projects for the future and in some 1663 01:09:12,709 --> 01:09:10,640 sense cal is a pathfinder for these kind 1664 01:09:13,669 --> 01:09:12,719 of ideas 1665 01:09:15,749 --> 01:09:13,679 uh 1666 01:09:17,510 --> 01:09:15,759 all these ideas will work better in zero 1667 01:09:19,269 --> 01:09:17,520 gravity uh 1668 01:09:21,189 --> 01:09:19,279 if we could replicate this whole project 1669 01:09:23,669 --> 01:09:21,199 of making bose einstein condensation in 1670 01:09:25,510 --> 01:09:23,679 space they would just hang there 1671 01:09:27,030 --> 01:09:25,520 and uh we could get much colder without 1672 01:09:29,110 --> 01:09:27,040 being bugged by whatever it is we are 1673 01:09:30,709 --> 01:09:29,120 keeping the slow slow-moving atoms from 1674 01:09:32,390 --> 01:09:30,719 just falling which is what happens here 1675 01:09:33,990 --> 01:09:32,400 on earth 1676 01:09:36,229 --> 01:09:34,000 what puts the cold of the cold atom 1677 01:09:38,070 --> 01:09:36,239 laboratory is it because space is cold 1678 01:09:40,550 --> 01:09:38,080 no we've just heard spaces honestly not 1679 01:09:43,510 --> 01:09:40,560 that cold three rays kelvin come on 1680 01:09:45,349 --> 01:09:43,520 um in on earth um 1681 01:09:47,269 --> 01:09:45,359 we have to hold these things in these in 1682 01:09:49,510 --> 01:09:47,279 these magnetic bowls 1683 01:09:51,110 --> 01:09:49,520 and uh i i mentioned five nano kelvin 1684 01:09:52,630 --> 01:09:51,120 which is about as cold 1685 01:09:54,950 --> 01:09:52,640 this is already a very very cold 1686 01:09:56,310 --> 01:09:54,960 temperature on earth not even routinely 1687 01:09:57,669 --> 01:09:56,320 observed 1688 01:09:59,350 --> 01:09:57,679 we learned 1689 01:10:01,750 --> 01:09:59,360 in high school physics that if you take 1690 01:10:03,990 --> 01:10:01,760 a gas and you expand it 1691 01:10:05,910 --> 01:10:04,000 it gets colder right ideal gas law all 1692 01:10:07,750 --> 01:10:05,920 that kind of stuff so we're holding 1693 01:10:09,110 --> 01:10:07,760 these things in a magnetic bowl easiest 1694 01:10:10,709 --> 01:10:09,120 thing in the world in the back for a 1695 01:10:12,790 --> 01:10:10,719 magnetic bowl is to turn down the 1696 01:10:14,630 --> 01:10:12,800 electric current going in the coils the 1697 01:10:17,270 --> 01:10:14,640 magnetic fields get weaker 1698 01:10:19,750 --> 01:10:17,280 the bowl gets goes from a deep bowl like 1699 01:10:21,910 --> 01:10:19,760 say like a tea a tea mug into a shallow 1700 01:10:23,510 --> 01:10:21,920 like a t saucer and you do that 1701 01:10:25,910 --> 01:10:23,520 gradually the atoms expand and they 1702 01:10:28,070 --> 01:10:25,920 should get colder just like you know pv 1703 01:10:30,470 --> 01:10:28,080 equals nkt you know the volume gets 1704 01:10:32,550 --> 01:10:30,480 bigger it should get colder but so why 1705 01:10:34,630 --> 01:10:32,560 don't we just do that and the problem is 1706 01:10:36,070 --> 01:10:34,640 at least here on earth is that the bowl 1707 01:10:37,270 --> 01:10:36,080 doesn't look like that it doesn't look 1708 01:10:39,030 --> 01:10:37,280 like a shallow bowl it looks like a 1709 01:10:40,790 --> 01:10:39,040 shallow bowl tilted on a side this is 1710 01:10:42,630 --> 01:10:40,800 gravity the atoms will slide on out and 1711 01:10:44,630 --> 01:10:42,640 they'll fall out screaming to their to 1712 01:10:45,430 --> 01:10:44,640 their infinite peril and that will be 1713 01:10:47,030 --> 01:10:45,440 that 1714 01:10:48,550 --> 01:10:47,040 where does this how does this connect 1715 01:10:50,390 --> 01:10:48,560 with uh 1716 01:10:51,990 --> 01:10:50,400 with gravity well i think uh christina 1717 01:10:53,669 --> 01:10:52,000 would be the first to tell you that in 1718 01:10:55,189 --> 01:10:53,679 earth in space no one can hear you 1719 01:10:57,110 --> 01:10:55,199 scream so the screaming 1720 01:10:59,350 --> 01:10:57,120 no that's not actually the reason um 1721 01:11:01,350 --> 01:10:59,360 it's actually because 1722 01:11:03,189 --> 01:11:01,360 uh there's effectively no gravity 1723 01:11:05,030 --> 01:11:03,199 basically in space so atoms don't fall 1724 01:11:06,950 --> 01:11:05,040 out of the trap we can basically do this 1725 01:11:09,030 --> 01:11:06,960 adiabatic expansion and get down into 1726 01:11:11,350 --> 01:11:09,040 temperatures that start with a 1727 01:11:14,470 --> 01:11:11,360 a p instead of with n p stands for 1728 01:11:16,470 --> 01:11:14,480 pretty darn cold 1729 01:11:18,550 --> 01:11:16,480 so why go to the trouble 1730 01:11:20,390 --> 01:11:18,560 detecting gravitational waves studying 1731 01:11:22,390 --> 01:11:20,400 the equivalence principle precision 1732 01:11:25,830 --> 01:11:22,400 orology which is a fancy name for really 1733 01:11:27,030 --> 01:11:25,840 good clocks uh dark matter cow will help 1734 01:11:29,350 --> 01:11:27,040 develop all of these relevant 1735 01:11:31,750 --> 01:11:29,360 technologies it's a step in all these 1736 01:11:33,350 --> 01:11:31,760 directions 1737 01:11:35,030 --> 01:11:33,360 we've already seen pictures behind you 1738 01:11:36,390 --> 01:11:35,040 can't see it but behind these folks 1739 01:11:37,910 --> 01:11:36,400 there are two 1740 01:11:41,830 --> 01:11:37,920 optical tables call them think of them 1741 01:11:43,750 --> 01:11:41,840 as large picnic tables full of stuff 1742 01:11:45,030 --> 01:11:43,760 and uh here's actually more modern 1743 01:11:46,790 --> 01:11:45,040 picture 1744 01:11:48,390 --> 01:11:46,800 this shin was one of the grad students 1745 01:11:50,950 --> 01:11:48,400 supported by cal 1746 01:11:53,030 --> 01:11:50,960 and so was vandy here more picnic tables 1747 01:11:54,390 --> 01:11:53,040 more stuff when i first heard about cal 1748 01:11:55,750 --> 01:11:54,400 they said we're gonna take all this 1749 01:11:56,790 --> 01:11:55,760 stuff we're gonna squeeze it all down 1750 01:11:58,390 --> 01:11:56,800 we're gonna put a box and we're gonna 1751 01:11:59,590 --> 01:11:58,400 send it up in a space where no one can 1752 01:12:01,430 --> 01:11:59,600 mess with it for years and years and 1753 01:12:03,590 --> 01:12:01,440 we'll make most einstein conversation 1754 01:12:05,669 --> 01:12:03,600 there and i said yeah right i don't 1755 01:12:07,110 --> 01:12:05,679 think so it's really really hard folks 1756 01:12:09,189 --> 01:12:07,120 this is not gonna it's not something you 1757 01:12:11,030 --> 01:12:09,199 can just like but they uh to my 1758 01:12:12,870 --> 01:12:11,040 astonishment honestly 1759 01:12:13,910 --> 01:12:12,880 uh i was reluctant to get involved in 1760 01:12:15,350 --> 01:12:13,920 the project because i thought there was 1761 01:12:17,750 --> 01:12:15,360 no way in heck this is ever going to 1762 01:12:19,590 --> 01:12:17,760 work but it did which is really pretty 1763 01:12:21,510 --> 01:12:19,600 freaking amazing congratulations cal 1764 01:12:22,550 --> 01:12:21,520 folks that's astonishing can we just 1765 01:12:28,550 --> 01:12:22,560 have a round of applause that was an 1766 01:12:32,470 --> 01:12:30,070 uh and we've heard a little bit about it 1767 01:12:34,229 --> 01:12:32,480 at the heart is a chip which was made by 1768 01:12:36,310 --> 01:12:34,239 a company owned by my pal here dana 1769 01:12:38,070 --> 01:12:36,320 anderson here the chip's about an inch 1770 01:12:40,790 --> 01:12:38,080 on a side i think here at nasa we say 1771 01:12:42,229 --> 01:12:40,800 2.54 centimeters give or take 1772 01:12:44,390 --> 01:12:42,239 and it's got little wires that make the 1773 01:12:47,110 --> 01:12:44,400 magnetic fields for the traps that in 1774 01:12:48,790 --> 01:12:47,120 turn goes into a sort of a scientific 1775 01:12:51,110 --> 01:12:48,800 environment about the size of a loaf of 1776 01:12:53,990 --> 01:12:51,120 bread that thing goes into i always 1777 01:12:55,510 --> 01:12:54,000 think of this as the dorm fridge 1778 01:12:57,350 --> 01:12:55,520 maybe it's more like a hotel fridge it's 1779 01:12:59,110 --> 01:12:57,360 about the size of a dorm fridge i still 1780 01:13:01,430 --> 01:12:59,120 remember my college days when people had 1781 01:13:03,189 --> 01:13:01,440 dorm fridges 1782 01:13:04,790 --> 01:13:03,199 and then that whole thing gets sent up 1783 01:13:06,709 --> 01:13:04,800 into the international space station and 1784 01:13:09,030 --> 01:13:06,719 it's thanks to 1785 01:13:11,430 --> 01:13:09,040 generous funding 1786 01:13:13,350 --> 01:13:11,440 a home and space 1787 01:13:15,030 --> 01:13:13,360 people to design and build this amazing 1788 01:13:18,550 --> 01:13:15,040 thing 1789 01:13:20,390 --> 01:13:18,560 the original truly quantum mechanics who 1790 01:13:22,070 --> 01:13:20,400 who put the thing up on the rack and 1791 01:13:24,070 --> 01:13:22,080 change the oil or whatever it is that 1792 01:13:26,310 --> 01:13:24,080 needs to happen i can't believe i can't 1793 01:13:27,270 --> 01:13:26,320 imagine doing that in space 1794 01:13:29,350 --> 01:13:27,280 and 1795 01:13:32,070 --> 01:13:29,360 but yes turns out as we've heard is 1796 01:13:34,149 --> 01:13:32,080 possible to do keep the thing running 1797 01:13:35,590 --> 01:13:34,159 for the cold adam laboratory 1798 01:13:37,350 --> 01:13:35,600 we've seen some of these pictures 1799 01:13:38,790 --> 01:13:37,360 already 1800 01:13:40,630 --> 01:13:38,800 again these are these pictures are not 1801 01:13:42,229 --> 01:13:40,640 taken in space but again basically they 1802 01:13:44,229 --> 01:13:42,239 turn off the cloud they turn off the 1803 01:13:45,350 --> 01:13:44,239 magnetic trap the atoms just kind of 1804 01:13:47,830 --> 01:13:45,360 hang there 1805 01:13:49,830 --> 01:13:47,840 and they gradually expand because 1806 01:13:51,510 --> 01:13:49,840 they're not exactly at zero temperature 1807 01:13:53,430 --> 01:13:51,520 and after they're expanded for some time 1808 01:13:55,110 --> 01:13:53,440 they take a picture and you see this is 1809 01:13:57,430 --> 01:13:55,120 a representation of the density of the 1810 01:13:59,030 --> 01:13:57,440 cloud and it's getting as it's heading 1811 01:14:00,470 --> 01:13:59,040 towards both einstein condensate it gets 1812 01:14:02,550 --> 01:14:00,480 smaller and smaller and smaller and 1813 01:14:05,270 --> 01:14:02,560 suddenly the spike shows up and those 1814 01:14:07,910 --> 01:14:05,280 spikes like that spike right there is uh 1815 01:14:09,990 --> 01:14:07,920 thousands of atoms all doing all doing 1816 01:14:11,030 --> 01:14:10,000 exactly the same way think of it as like 1817 01:15:16,790 --> 01:14:11,040 a 1818 01:15:19,590 --> 01:15:16,800 zero 1819 01:15:20,870 --> 01:15:19,600 uh for people who who speak metric pico 1820 01:15:23,110 --> 01:15:20,880 is you know 1821 01:15:24,390 --> 01:15:23,120 is to nano as you know micro is to milly 1822 01:15:25,990 --> 01:15:24,400 or whatever it's a thousand times 1823 01:15:27,189 --> 01:15:26,000 smaller these are extraordinarily low 1824 01:15:30,470 --> 01:15:27,199 temperatures 1825 01:15:31,990 --> 01:15:30,480 and made possible by being in space 1826 01:15:33,750 --> 01:15:32,000 um 1827 01:15:35,750 --> 01:15:33,760 this uh people have already alluded to 1828 01:15:38,550 --> 01:15:35,760 this ability to make condensates of two 1829 01:15:39,910 --> 01:15:38,560 different species they appear on one 1830 01:15:41,110 --> 01:15:39,920 side of screen or the other but i want 1831 01:15:42,950 --> 01:15:41,120 to emphasize they're actually sitting 1832 01:15:44,470 --> 01:15:42,960 right on top of each other why would you 1833 01:15:46,550 --> 01:15:44,480 want to do that 1834 01:15:48,229 --> 01:15:46,560 it turns out that 1835 01:15:50,149 --> 01:15:48,239 when you're doing interferometric 1836 01:15:51,430 --> 01:15:50,159 studies for instance of how atoms fall 1837 01:15:52,709 --> 01:15:51,440 under gravity 1838 01:15:54,070 --> 01:15:52,719 there are a lot of possible these are 1839 01:15:55,669 --> 01:15:54,080 precision measurements there's a lot of 1840 01:15:57,590 --> 01:15:55,679 possible sources for air when you make 1841 01:15:59,189 --> 01:15:57,600 precision measurements you'd like to 1842 01:16:00,470 --> 01:15:59,199 cancel out those sources of air and the 1843 01:16:02,390 --> 01:16:00,480 way to do that is by doing a 1844 01:16:04,630 --> 01:16:02,400 differential measurement you measure 1845 01:16:06,310 --> 01:16:04,640 something simultaneously exactly 1846 01:16:09,350 --> 01:16:06,320 overlapping with one species and with 1847 01:16:11,110 --> 01:16:09,360 the other species and most of the errors 1848 01:16:12,630 --> 01:16:11,120 are common mode and subtract out and the 1849 01:16:15,350 --> 01:16:12,640 the physics you want to extract from 1850 01:16:17,270 --> 01:16:15,360 that is it lies in the difference 1851 01:16:18,870 --> 01:16:17,280 uh and i can't can't stop without 1852 01:16:21,350 --> 01:16:18,880 mentioning the experiment i myself am 1853 01:16:22,950 --> 01:16:21,360 working on with my friends my colleagues 1854 01:16:25,189 --> 01:16:22,960 who are here uh 1855 01:16:27,270 --> 01:16:25,199 marin and peter in which we're trying to 1856 01:16:29,110 --> 01:16:27,280 create molecules three atom molecules 1857 01:16:31,750 --> 01:16:29,120 that are about the size of an e coli 1858 01:16:34,630 --> 01:16:31,760 atom so that's like the 1859 01:16:36,870 --> 01:16:34,640 loosest tiniest fluffiest atom molecule 1860 01:16:38,790 --> 01:16:36,880 you've ever seen held together by purely 1861 01:16:40,709 --> 01:16:38,800 quantum mechanical forces we're not 1862 01:16:42,390 --> 01:16:40,719 quite there but soon i hope 1863 01:16:51,669 --> 01:16:42,400 at that point i'm going to stop and 1864 01:16:55,669 --> 01:16:53,270 so folks we are now going to start 1865 01:16:57,430 --> 01:16:55,679 opening it up for q and a q a but as 1866 01:16:59,510 --> 01:16:57,440 they work their way over to their chairs 1867 01:17:01,270 --> 01:16:59,520 over there i want to give a big round of 1868 01:17:03,270 --> 01:17:01,280 applause and a thank you for all of our 1869 01:17:04,790 --> 01:17:03,280 speakers coming from far and wide to be 1870 01:17:06,229 --> 01:17:04,800 here and talk about this amazing mission 1871 01:17:12,950 --> 01:17:06,239 so one big round of applause again for 1872 01:17:17,270 --> 01:17:14,550 our first question we're actually going 1873 01:17:19,189 --> 01:17:17,280 to take from online 1874 01:17:20,630 --> 01:17:19,199 if you're in-house we're going to you 1875 01:17:22,470 --> 01:17:20,640 can step up to the microphones but we'll 1876 01:17:24,870 --> 01:17:22,480 get an online question first we're going 1877 01:17:26,310 --> 01:17:24,880 to go for probably the next 12 13 1878 01:17:28,550 --> 01:17:26,320 minutes if we don't get to your question 1879 01:17:31,669 --> 01:17:28,560 we do apologize for that 1880 01:17:35,430 --> 01:17:31,679 but a question from youtube uh is asked 1881 01:17:36,870 --> 01:17:35,440 how has cal helped us in our daily life 1882 01:17:39,110 --> 01:17:36,880 and i guess which one wants to take this 1883 01:17:40,229 --> 01:17:39,120 one 1884 01:17:42,630 --> 01:17:40,239 oh 1885 01:17:44,550 --> 01:17:42,640 i'll take a crack at it um 1886 01:17:47,910 --> 01:17:44,560 i feel like uh 1887 01:17:50,630 --> 01:17:47,920 so far not so much to be fair 1888 01:17:52,229 --> 01:17:50,640 uh but if the history of technology 1889 01:17:53,669 --> 01:17:52,239 tells us anything it's that the future 1890 01:17:56,310 --> 01:17:53,679 lies in the direction of the very very 1891 01:17:59,669 --> 01:17:56,320 small and um 1892 01:18:01,110 --> 01:17:59,679 our daily lives are improved by so many 1893 01:18:02,470 --> 01:18:01,120 things 1894 01:18:04,149 --> 01:18:02,480 which are involved you know whether 1895 01:18:05,590 --> 01:18:04,159 they're medical devices whether they're 1896 01:18:07,510 --> 01:18:05,600 electronics whether they're computers 1897 01:18:09,590 --> 01:18:07,520 whether it's communication which are 1898 01:18:11,750 --> 01:18:09,600 based on these tiny little chips as they 1899 01:18:13,590 --> 01:18:11,760 get smaller and smaller the rules of 1900 01:18:15,669 --> 01:18:13,600 classical physics no longer apply and 1901 01:18:18,149 --> 01:18:15,679 quantum mechanics take over 1902 01:18:19,830 --> 01:18:18,159 if you want to continue in along this 1903 01:18:21,350 --> 01:18:19,840 trajectory towards making the useful 1904 01:18:24,390 --> 01:18:21,360 things that we want to buy and have in 1905 01:18:26,390 --> 01:18:24,400 our house we need to have a deeper more 1906 01:18:28,470 --> 01:18:26,400 gut level understanding of quantum 1907 01:18:30,149 --> 01:18:28,480 mechanics and there's nothing more gut 1908 01:18:31,910 --> 01:18:30,159 level than just being able to straight 1909 01:18:33,750 --> 01:18:31,920 see a picture of quantum mechanics 1910 01:18:35,910 --> 01:18:33,760 happening so there's a sense in which 1911 01:18:37,669 --> 01:18:35,920 these kind of studies represent a sort 1912 01:18:39,510 --> 01:18:37,679 of 1913 01:18:42,470 --> 01:18:39,520 i don't want to call it a playground but 1914 01:18:44,390 --> 01:18:42,480 uh basically a a working laboratory to 1915 01:18:46,470 --> 01:18:44,400 understand this physics which sort of 1916 01:18:49,189 --> 01:18:46,480 enables so much of the technology that 1917 01:18:51,990 --> 01:18:49,199 is underlies commerce and industry and 1918 01:18:52,830 --> 01:18:52,000 and household products 1919 01:18:54,950 --> 01:18:52,840 very 1920 01:18:57,430 --> 01:18:54,960 cool um we'll go to another question 1921 01:19:00,070 --> 01:18:57,440 from online marina on youtube asks can 1922 01:19:02,149 --> 01:19:00,080 the cold adam lab reconcile and unite 1923 01:19:05,110 --> 01:19:02,159 quantum physics and relativity and 1924 01:19:07,270 --> 01:19:05,120 relativity theory 1925 01:19:09,830 --> 01:19:07,280 yeah i guess i should take that one 1926 01:19:12,149 --> 01:19:09,840 [Laughter] 1927 01:19:17,430 --> 01:19:15,750 all of these technologies are are 1928 01:19:18,630 --> 01:19:17,440 relatively new i would should say 1929 01:19:20,470 --> 01:19:18,640 especially 1930 01:19:22,470 --> 01:19:20,480 the promise that 1931 01:19:24,310 --> 01:19:22,480 we're going to use these cold atoms in 1932 01:19:27,590 --> 01:19:24,320 order to 1933 01:19:29,990 --> 01:19:27,600 make very impactful statements about um 1934 01:19:31,669 --> 01:19:30,000 about fundamental physics it's it's not 1935 01:19:34,310 --> 01:19:31,679 expected that 1936 01:19:35,270 --> 01:19:34,320 cold atom lab in its current state will 1937 01:19:37,430 --> 01:19:35,280 measure 1938 01:19:39,510 --> 01:19:37,440 equivalence principle to date 18 digit 1939 01:19:41,990 --> 01:19:39,520 points or or make some definitive 1940 01:19:43,750 --> 01:19:42,000 statements about uh string theory or 1941 01:19:47,669 --> 01:19:43,760 something like that but 1942 01:19:49,990 --> 01:19:47,679 it is a necessary first step and a large 1943 01:19:53,430 --> 01:19:50,000 leap i would say to to get us there this 1944 01:19:55,750 --> 01:19:53,440 is a technology pathfinder that has 1945 01:19:57,270 --> 01:19:55,760 to me surpassed what the technology we 1946 01:19:58,870 --> 01:19:57,280 were trying to pathfind and is now 1947 01:20:01,590 --> 01:19:58,880 actually has the dual species out of 1948 01:20:04,390 --> 01:20:01,600 interferometry people are some of our 1949 01:20:06,550 --> 01:20:04,400 pis are working on it to actually do 1950 01:20:08,550 --> 01:20:06,560 some preliminary tests of say the 1951 01:20:11,270 --> 01:20:08,560 equivalence principle and and see if 1952 01:20:13,270 --> 01:20:11,280 it's possible and from there we have the 1953 01:20:16,550 --> 01:20:13,280 knowledge now we have that basis to 1954 01:20:18,229 --> 01:20:16,560 build um defined facilities that will be 1955 01:20:19,910 --> 01:20:18,239 able to go in and really probe where we 1956 01:20:22,629 --> 01:20:19,920 need to and understand 1957 01:20:24,470 --> 01:20:22,639 uh and make some definitive statements 1958 01:20:28,550 --> 01:20:24,480 so i would like to add 1959 01:20:32,790 --> 01:20:28,560 if we think of the mars programs like 1960 01:20:35,910 --> 01:20:32,800 recently i mean we've landed two huge 1961 01:20:37,270 --> 01:20:35,920 rovers uh curiosity 1962 01:20:40,550 --> 01:20:37,280 and 1963 01:20:44,310 --> 01:20:40,560 perseverance they're like over 960 1964 01:20:47,750 --> 01:20:44,320 kilograms well we didn't just do it 1965 01:20:49,590 --> 01:20:47,760 just on the first goal we had to send 1966 01:20:52,709 --> 01:20:49,600 like sujourno 1967 01:20:55,030 --> 01:20:52,719 and learn from that then we went to 1968 01:20:57,830 --> 01:20:55,040 mars exploration rovers and john can 1969 01:21:00,149 --> 01:20:57,840 tell you and then we learned 1970 01:21:02,149 --> 01:21:00,159 and we built on this knowledge before we 1971 01:21:03,830 --> 01:21:02,159 could land something that big so i feel 1972 01:21:04,790 --> 01:21:03,840 like the same thing with the cold atom 1973 01:21:08,229 --> 01:21:04,800 lab 1974 01:21:09,830 --> 01:21:08,239 it's uh pathfinder and the ability to be 1975 01:21:12,870 --> 01:21:09,840 able to 1976 01:21:15,830 --> 01:21:12,880 extract like two two separate atoms or 1977 01:21:18,310 --> 01:21:15,840 or cloud of atoms like potassium and 1978 01:21:20,870 --> 01:21:18,320 rubidium and 1979 01:21:22,870 --> 01:21:20,880 potassium is is lighter than rubidium 1980 01:21:25,350 --> 01:21:22,880 and to be able to control and release 1981 01:21:28,390 --> 01:21:25,360 them at the right time and and be able 1982 01:21:31,590 --> 01:21:28,400 to observe which one hits you know the 1983 01:21:33,910 --> 01:21:31,600 the platform first that's a huge leap 1984 01:21:36,390 --> 01:21:33,920 that we couldn't have done uh five years 1985 01:21:37,910 --> 01:21:36,400 ago so anyway thanks i just want to add 1986 01:21:39,510 --> 01:21:37,920 this fantastic we actually have a 1987 01:21:41,510 --> 01:21:39,520 question in the house right now over 1988 01:21:44,550 --> 01:21:41,520 here on the right side 1989 01:21:47,189 --> 01:21:44,560 hello um i was wondering how can you use 1990 01:21:49,669 --> 01:21:47,199 the cold atom lab to understand or 1991 01:21:51,750 --> 01:21:49,679 detect dark matter you guys mentioned 1992 01:21:55,669 --> 01:21:51,760 that it was like related to that but how 1993 01:21:59,669 --> 01:21:57,510 okay yeah i can take a first crack at it 1994 01:22:01,669 --> 01:21:59,679 and i'm happy for anybody else to 1995 01:22:04,390 --> 01:22:01,679 uh to jump into that because this is 1996 01:22:06,390 --> 01:22:04,400 really a branch of research that has 1997 01:22:08,709 --> 01:22:06,400 been a pleasant surprise that has 1998 01:22:12,550 --> 01:22:08,719 cropped up over the last decade or so i 1999 01:22:14,149 --> 01:22:12,560 should say so um dark matter emerges as 2000 01:22:15,990 --> 01:22:14,159 subtle forces in our universe that we 2001 01:22:18,470 --> 01:22:16,000 don't understand um 2002 01:22:19,430 --> 01:22:18,480 and these are um there's been a lot of 2003 01:22:21,590 --> 01:22:19,440 search 2004 01:22:24,470 --> 01:22:21,600 over the last decades for what is the 2005 01:22:27,270 --> 01:22:24,480 essence of dark matter could it be some 2006 01:22:28,629 --> 01:22:27,280 some particle that interacts with matter 2007 01:22:31,990 --> 01:22:28,639 but we can't see 2008 01:22:34,149 --> 01:22:32,000 there is a class of dark matter that is 2009 01:22:36,790 --> 01:22:34,159 ultralight and so the idea that there 2010 01:22:37,910 --> 01:22:36,800 are some very many very light particles 2011 01:22:40,629 --> 01:22:37,920 but enough of them that they're 2012 01:22:42,629 --> 01:22:40,639 pervasive in our universe and the 2013 01:22:45,590 --> 01:22:42,639 influence of these ultralight particles 2014 01:22:47,990 --> 01:22:45,600 might give subtle forces on quantum 2015 01:22:50,229 --> 01:22:48,000 gases that could be perceptible and so 2016 01:22:51,750 --> 01:22:50,239 we could actually have a complementary 2017 01:22:54,390 --> 01:22:51,760 new type of measurement that no other 2018 01:22:56,629 --> 01:22:54,400 apparatus could could possibly be used 2019 01:22:59,750 --> 01:22:56,639 or could possibly see this unique class 2020 01:23:01,510 --> 01:22:59,760 of dark matter that um is feasible uh 2021 01:23:03,189 --> 01:23:01,520 that could explain 2022 01:23:04,229 --> 01:23:03,199 the unknown nature of 2023 01:23:05,669 --> 01:23:04,239 of uh 2024 01:23:08,950 --> 01:23:05,679 strange forces on our universe that 2025 01:23:10,149 --> 01:23:08,960 don't yet have an explanation 2026 01:23:12,229 --> 01:23:10,159 thanks 2027 01:23:14,550 --> 01:23:12,239 very cool we have another question from 2028 01:23:17,270 --> 01:23:14,560 facebook this time um 2029 01:23:19,189 --> 01:23:17,280 this is really focused on atoms is it 2030 01:23:20,790 --> 01:23:19,199 possible to focus on molecules is it 2031 01:23:22,950 --> 01:23:20,800 possible to focus on even more specific 2032 01:23:25,270 --> 01:23:22,960 parts from this point or is atoms kind 2033 01:23:26,149 --> 01:23:25,280 of where we want to be with this 2034 01:23:31,669 --> 01:23:26,159 um 2035 01:23:33,189 --> 01:23:31,679 you have may have heard like 2036 01:23:34,550 --> 01:23:33,199 people haven't talked about it but words 2037 01:23:37,750 --> 01:23:34,560 have appeared of the slides like 2038 01:23:39,910 --> 01:23:37,760 feshbach and ephemoth which sound uh 2039 01:23:42,149 --> 01:23:39,920 you know just like exotic names but in 2040 01:23:44,709 --> 01:23:42,159 in fact they refer really to molecules 2041 01:23:46,390 --> 01:23:44,719 uh feshbach residences are what happens 2042 01:23:47,669 --> 01:23:46,400 when you take two atoms and you adjust 2043 01:23:49,510 --> 01:23:47,679 the magnetic field and they stick 2044 01:23:51,750 --> 01:23:49,520 together to form molecules and these are 2045 01:23:54,229 --> 01:23:51,760 projects which are very much ongoing 2046 01:23:55,669 --> 01:23:54,239 soon i think they'll be making 2047 01:23:57,510 --> 01:23:55,679 molecules 2048 01:23:59,750 --> 01:23:57,520 of okay in this case rubidium and 2049 01:24:02,070 --> 01:23:59,760 potassium stuck together we're working 2050 01:24:03,669 --> 01:24:02,080 on trying to make three potassium atoms 2051 01:24:05,189 --> 01:24:03,679 stuck together into a three atom 2052 01:24:06,310 --> 01:24:05,199 molecule 2053 01:24:07,750 --> 01:24:06,320 and 2054 01:24:09,669 --> 01:24:07,760 these are 2055 01:24:11,189 --> 01:24:09,679 molecules which you know no chemist 2056 01:24:13,110 --> 01:24:11,199 would recognize if you wrote them down 2057 01:24:14,390 --> 01:24:13,120 on your on your on a chemistry exam in 2058 01:24:16,310 --> 01:24:14,400 high school it would be marked wrong 2059 01:24:18,229 --> 01:24:16,320 this is not a molecule you know it 2060 01:24:19,910 --> 01:24:18,239 doesn't obey any of the rules but that's 2061 01:24:21,430 --> 01:24:19,920 sort of what makes them fun is these are 2062 01:24:23,430 --> 01:24:21,440 molecules that violate most of the 2063 01:24:25,030 --> 01:24:23,440 chemistry rules just because they're so 2064 01:24:26,390 --> 01:24:25,040 lightly bound they're sort of little 2065 01:24:28,629 --> 01:24:26,400 balls of fluff 2066 01:24:31,430 --> 01:24:28,639 and they are sort of pure purely quantum 2067 01:24:33,590 --> 01:24:31,440 mechanical objects 2068 01:24:35,510 --> 01:24:33,600 fantastic we do have another question 2069 01:24:37,030 --> 01:24:35,520 here inside the house as well wearing a 2070 01:24:39,590 --> 01:24:37,040 great mars shirt 2071 01:24:42,310 --> 01:24:39,600 hi my name is amy and i'm an engineer on 2072 01:24:43,830 --> 01:24:42,320 the mission ops for march 2020 and i was 2073 01:24:45,430 --> 01:24:43,840 wondering how did you figure out what 2074 01:24:47,350 --> 01:24:45,440 you're most passionate about and do you 2075 01:24:49,510 --> 01:24:47,360 have any advice for navigating your 2076 01:24:50,390 --> 01:24:49,520 career especially for any students in 2077 01:24:51,990 --> 01:24:50,400 the room 2078 01:24:53,910 --> 01:24:52,000 i think everybody can take a crack at 2079 01:24:55,510 --> 01:24:53,920 this one let's start with uh christina 2080 01:24:58,390 --> 01:24:55,520 since you guys took the other hard ones 2081 01:24:59,990 --> 01:24:58,400 i'll i'll take a crack um 2082 01:25:01,830 --> 01:25:00,000 great question 2083 01:25:05,030 --> 01:25:01,840 when i 2084 01:25:07,030 --> 01:25:05,040 found myself at the many many crossroads 2085 01:25:09,270 --> 01:25:07,040 that you you find yourself at in a 2086 01:25:10,950 --> 01:25:09,280 career or in school 2087 01:25:12,470 --> 01:25:10,960 choosing a school choosing a major 2088 01:25:14,390 --> 01:25:12,480 choosing what to do after school 2089 01:25:17,669 --> 01:25:14,400 choosing whether to take time off 2090 01:25:19,590 --> 01:25:17,679 i had that same question how do you know 2091 01:25:21,350 --> 01:25:19,600 the right path how do you know what 2092 01:25:23,750 --> 01:25:21,360 you're truly passionate about and what's 2093 01:25:26,149 --> 01:25:23,760 going to lead you to not only flourish 2094 01:25:27,669 --> 01:25:26,159 the most and get the most rewarding life 2095 01:25:29,110 --> 01:25:27,679 that you can have but to give the most 2096 01:25:30,390 --> 01:25:29,120 back to the world 2097 01:25:31,910 --> 01:25:30,400 and 2098 01:25:34,229 --> 01:25:31,920 one of the things i would always do is 2099 01:25:36,870 --> 01:25:34,239 go back to what 2100 01:25:38,550 --> 01:25:36,880 i imagined for myself there's a quote i 2101 01:25:41,270 --> 01:25:38,560 think it's a thorough quote 2102 01:25:44,070 --> 01:25:41,280 live the life you imagined and that is 2103 01:25:45,990 --> 01:25:44,080 actually something that i think about i 2104 01:25:47,750 --> 01:25:46,000 think about when i was eight what did i 2105 01:25:48,550 --> 01:25:47,760 picture myself doing when i would grow 2106 01:25:51,030 --> 01:25:48,560 up 2107 01:25:51,910 --> 01:25:51,040 and i actually 2108 01:25:54,629 --> 01:25:51,920 would 2109 01:25:56,550 --> 01:25:54,639 remember those memories and try to think 2110 01:25:58,709 --> 01:25:56,560 about how i could create that life and i 2111 01:26:00,790 --> 01:25:58,719 really did see myself 2112 01:26:02,550 --> 01:26:00,800 being a space science nerd 2113 01:26:04,229 --> 01:26:02,560 and even though i grew up in a small 2114 01:26:06,310 --> 01:26:04,239 town in north carolina and i would 2115 01:26:09,030 --> 01:26:06,320 follow that path 2116 01:26:10,470 --> 01:26:09,040 another thing that i say is do what 2117 01:26:12,310 --> 01:26:10,480 scares you 2118 01:26:13,830 --> 01:26:12,320 and what i mean by that is don't take 2119 01:26:15,510 --> 01:26:13,840 unnecessary risk or anything like that 2120 01:26:17,750 --> 01:26:15,520 but um 2121 01:26:19,990 --> 01:26:17,760 think about the things that intrigue you 2122 01:26:21,510 --> 01:26:20,000 but that you feel like are maybe outside 2123 01:26:23,350 --> 01:26:21,520 of your grasp 2124 01:26:25,910 --> 01:26:23,360 and that's the direction you actually 2125 01:26:28,709 --> 01:26:25,920 have to go in not away from 2126 01:26:30,070 --> 01:26:28,719 it turns out that can tell you what 2127 01:26:31,430 --> 01:26:30,080 interests you 2128 01:26:33,830 --> 01:26:31,440 and also where you're going to get the 2129 01:26:35,270 --> 01:26:33,840 most reward out of because it's probably 2130 01:26:37,910 --> 01:26:35,280 challenging and that's why it's a little 2131 01:26:39,669 --> 01:26:37,920 scary and when you do it you actually 2132 01:26:41,270 --> 01:26:39,679 see what you're capable of and you 2133 01:26:42,950 --> 01:26:41,280 probably have pushed yourself to give 2134 01:26:45,430 --> 01:26:42,960 more back to the world those are some of 2135 01:26:47,430 --> 01:26:45,440 my guiding lights 2136 01:26:49,270 --> 01:26:47,440 yeah thank you christian i the only 2137 01:26:51,830 --> 01:26:49,280 thing i would like to add just basically 2138 01:26:52,870 --> 01:26:51,840 what you just said summarize it in the 2139 01:26:55,590 --> 01:26:52,880 fact that 2140 01:26:57,270 --> 01:26:55,600 when you reach outside your comfort zone 2141 01:26:58,310 --> 01:26:57,280 that's when you learn 2142 01:26:59,669 --> 01:26:58,320 and 2143 01:27:02,790 --> 01:26:59,679 that's really 2144 01:27:03,750 --> 01:27:02,800 what you are kind of conveying 2145 01:27:06,149 --> 01:27:03,760 and 2146 01:27:07,430 --> 01:27:06,159 called adam lab is one example because i 2147 01:27:10,470 --> 01:27:07,440 think 2148 01:27:12,310 --> 01:27:10,480 i mean you heard even from eric uh 2149 01:27:14,390 --> 01:27:12,320 like he had doubts 2150 01:27:16,310 --> 01:27:14,400 and uh 2151 01:27:18,950 --> 01:27:16,320 it's good to have doubts because then 2152 01:27:22,070 --> 01:27:18,960 you you set some criteria that you have 2153 01:27:25,830 --> 01:27:22,080 to convince the right people that that 2154 01:27:27,669 --> 01:27:25,840 you have the right plan and so 2155 01:27:29,990 --> 01:27:27,679 many of these missions we've 2156 01:27:32,790 --> 01:27:30,000 accomplished here at jpl when you talk 2157 01:27:35,270 --> 01:27:32,800 to the people they had to step outside 2158 01:27:37,910 --> 01:27:35,280 their comfort zone to think about ideas 2159 01:27:38,950 --> 01:27:37,920 or even how to implement them 2160 01:27:43,189 --> 01:27:38,960 so 2161 01:27:45,030 --> 01:27:43,199 course passion because i mean fact that 2162 01:27:46,550 --> 01:27:45,040 you're here at gpl you must be 2163 01:27:48,229 --> 01:27:46,560 passionate about what you 2164 01:27:50,070 --> 01:27:48,239 what you're doing 2165 01:27:51,669 --> 01:27:50,080 so we've got two last questions in the 2166 01:27:53,030 --> 01:27:51,679 house that we'll get to uh and then 2167 01:27:55,110 --> 01:27:53,040 we'll wrap it up so we'll start over 2168 01:28:00,149 --> 01:27:55,120 here 2169 01:28:02,229 --> 01:28:00,159 jpl so thank you so much for coming and 2170 01:28:04,550 --> 01:28:02,239 speaking we have many of our students in 2171 01:28:07,990 --> 01:28:04,560 the audience today and it's it's really 2172 01:28:09,990 --> 01:28:08,000 important to them to hear you today 2173 01:28:12,629 --> 01:28:10,000 all of your different backgrounds that 2174 01:28:14,790 --> 01:28:12,639 was a great question about about interns 2175 01:28:17,270 --> 01:28:14,800 and i was wondering if you had something 2176 01:28:19,590 --> 01:28:17,280 that you could share just a lash lasting 2177 01:28:21,189 --> 01:28:19,600 piece of advice or um impression about 2178 01:28:22,709 --> 01:28:21,199 each of your you know we have a project 2179 01:28:24,470 --> 01:28:22,719 manager you have a project scientist an 2180 01:28:26,149 --> 01:28:24,480 astronaut a nobel laureate what is 2181 01:28:28,229 --> 01:28:26,159 something that was very impactful like a 2182 01:28:29,910 --> 01:28:28,239 one-liner that they could take with them 2183 01:28:31,510 --> 01:28:29,920 many of them are ending their 10-week 2184 01:28:32,790 --> 01:28:31,520 internships and they're going on to 2185 01:28:34,790 --> 01:28:32,800 their next steps some of them are 2186 01:28:36,149 --> 01:28:34,800 getting extended so just something to 2187 01:28:39,990 --> 01:28:36,159 leave with them as they 2188 01:28:45,510 --> 01:28:41,669 something to continue on as they go into 2189 01:28:50,950 --> 01:28:48,310 okay i'll just give a quick piece of 2190 01:28:51,669 --> 01:28:50,960 advice that i learned that um 2191 01:28:58,070 --> 01:28:51,679 you 2192 01:29:00,149 --> 01:28:58,080 have 2193 01:29:01,590 --> 01:29:00,159 some of them uh people might know when 2194 01:29:03,030 --> 01:29:01,600 they've been in the field for a long 2195 01:29:04,709 --> 01:29:03,040 time but sometimes when people are in 2196 01:29:06,470 --> 01:29:04,719 the field for a long time 2197 01:29:08,629 --> 01:29:06,480 they they have been thinking about their 2198 01:29:11,270 --> 01:29:08,639 own project for a long time and it is 2199 01:29:13,510 --> 01:29:11,280 really beneficial for us to hear your 2200 01:29:15,030 --> 01:29:13,520 insights and your your contributions so 2201 01:29:17,590 --> 01:29:15,040 so yeah never feel 2202 01:29:20,070 --> 01:29:17,600 intimidated 2203 01:29:22,470 --> 01:29:20,080 all right so you've heard about reach 2204 01:29:24,950 --> 01:29:22,480 outside your comfort zone there is one 2205 01:29:27,110 --> 01:29:24,960 other important 2206 01:29:29,590 --> 01:29:27,120 at least lesson for me 2207 01:29:31,350 --> 01:29:29,600 that i'm reminded by this like whether 2208 01:29:33,910 --> 01:29:31,360 you know from a project site or science 2209 01:29:35,430 --> 01:29:33,920 site you have to be 2210 01:29:37,350 --> 01:29:35,440 able to 2211 01:29:40,070 --> 01:29:37,360 recalibrate meaning 2212 01:29:42,950 --> 01:29:40,080 you have to be flexible when you show up 2213 01:29:43,910 --> 01:29:42,960 to work you think that plan a is going 2214 01:29:48,870 --> 01:29:43,920 to work 2215 01:29:51,669 --> 01:29:48,880 then you have to be flexible to always 2216 01:29:54,229 --> 01:29:51,679 turn to plan b or even plan c and not 2217 01:29:55,270 --> 01:29:54,239 let that deter you from the 2218 01:29:57,910 --> 01:29:55,280 goal 2219 01:29:59,510 --> 01:29:57,920 so nothing that we do here 2220 01:30:01,430 --> 01:29:59,520 is kind of something you're gonna find 2221 01:30:03,669 --> 01:30:01,440 in the textbook so you have to figure it 2222 01:30:05,590 --> 01:30:03,679 out on your own and the only thing that 2223 01:30:07,750 --> 01:30:05,600 how you can be successful whether with 2224 01:30:10,629 --> 01:30:07,760 your team you work with or in your 2225 01:30:12,550 --> 01:30:10,639 career you have to be flexible and able 2226 01:30:14,550 --> 01:30:12,560 to recalibrate 2227 01:30:17,030 --> 01:30:14,560 thank you all right our last question of 2228 01:30:18,310 --> 01:30:17,040 the day right over here 2229 01:30:19,750 --> 01:30:18,320 hello i'm 2230 01:30:21,270 --> 01:30:19,760 one of the interns that's finishing in 2231 01:30:23,669 --> 01:30:21,280 two weeks but i did have a quick 2232 01:30:26,070 --> 01:30:23,679 question just about the science so 2233 01:30:27,669 --> 01:30:26,080 so 50 pico kelvins that's pretty cold i 2234 01:30:29,270 --> 01:30:27,679 was wondering if you thought that that's 2235 01:30:30,709 --> 01:30:29,280 something you'd only find in a 2236 01:30:32,550 --> 01:30:30,719 laboratory setting or if there's 2237 01:30:34,149 --> 01:30:32,560 somewhere out in the universe where 2238 01:30:39,110 --> 01:30:34,159 because of natural conditions it happens 2239 01:30:41,750 --> 01:30:40,390 okay so 2240 01:30:43,510 --> 01:30:41,760 if there's uh 2241 01:30:45,830 --> 01:30:43,520 i i don't think it's going to happen in 2242 01:30:47,430 --> 01:30:45,840 a natural way but i don't feel like that 2243 01:30:49,270 --> 01:30:47,440 rules out the possibility it's finding 2244 01:30:50,790 --> 01:30:49,280 elsewhere in the universe if there were 2245 01:30:53,030 --> 01:30:50,800 sort of the 2246 01:30:55,590 --> 01:30:53,040 the asf the alien space 2247 01:30:56,950 --> 01:30:55,600 science foundation on some distant star 2248 01:30:59,110 --> 01:30:56,960 they could they easily could have pico 2249
