launches less than one year away 86 00:03:17,990 --> 00:03:16,720 we're one year away from launch update 87 00:03:21,030 --> 00:03:18,000 the james webb space telescope 88 00:03:22,229 --> 00:03:21,040 we're excited about that uh we also have 89 00:03:24,309 --> 00:03:22,239 social media for the 90 00:03:25,589 --> 00:03:24,319 just our institute space telescope 91 00:03:27,430 --> 00:03:25,599 science institute 92 00:03:29,750 --> 00:03:27,440 uh facebook twitter youtube and 93 00:03:32,070 --> 00:03:29,760 instagram as listed there 94 00:03:33,030 --> 00:03:32,080 myself i only do a tiny amount of social 95 00:03:34,630 --> 00:03:33,040 media 96 00:03:36,949 --> 00:03:34,640 i'm going to do a little bit on facebook 97 00:03:38,789 --> 00:03:36,959 and a little bit on twitter 98 00:03:40,630 --> 00:03:38,799 you won't be inundated if you follow me 99 00:03:41,270 --> 00:03:40,640 you'll just get things every now and 100 00:03:44,470 --> 00:03:41,280 then 101 00:03:47,110 --> 00:03:44,480 okay so now 102 00:03:47,509 --> 00:03:47,120 our news from the universe for november 103 00:03:55,350 --> 00:03:47,519 to 104 00:03:58,470 --> 00:03:55,360 getting the big picture and we mean 105 00:04:00,309 --> 00:03:58,480 big picture all right so there's a new 106 00:04:04,789 --> 00:04:00,319 observatory going in 107 00:04:07,110 --> 00:04:04,799 in chile upon the sierra talolo in chile 108 00:04:08,309 --> 00:04:07,120 this is the reuben observatory named 109 00:04:11,270 --> 00:04:08,319 after the astronomer 110 00:04:12,390 --> 00:04:11,280 vera rubin and this is an image of it as 111 00:04:15,589 --> 00:04:12,400 it existed 112 00:04:18,469 --> 00:04:15,599 as it was in may of this year and it's 113 00:04:19,830 --> 00:04:18,479 progressing really well um they will 114 00:04:22,469 --> 00:04:19,840 start data taking 115 00:04:23,189 --> 00:04:22,479 sometime next year and they'll actually 116 00:04:26,950 --> 00:04:23,199 move into 117 00:04:29,670 --> 00:04:26,960 actually operational in 2022 i believe 118 00:04:30,710 --> 00:04:29,680 now this has got a huge mirror in it 119 00:04:33,830 --> 00:04:30,720 okay 120 00:04:34,710 --> 00:04:33,840 this is the mirror blank before it was 121 00:04:36,469 --> 00:04:34,720 aluminized 122 00:04:37,749 --> 00:04:36,479 uh to have its reflective surface it's 123 00:04:40,070 --> 00:04:37,759 an eight 124 00:04:41,110 --> 00:04:40,080 meters across this image just shows you 125 00:04:43,749 --> 00:04:41,120 just how 126 00:04:45,189 --> 00:04:43,759 huge this mirror is you can do that in a 127 00:04:48,550 --> 00:04:45,199 ground-based telescope 128 00:04:49,189 --> 00:04:48,560 and with a mirror this big you also need 129 00:04:52,710 --> 00:04:49,199 to have 130 00:04:53,790 --> 00:04:52,720 a big detector well they have one and 131 00:04:57,590 --> 00:04:53,800 it's called 132 00:05:00,710 --> 00:04:57,600 lsst cam all right and this is a 133 00:05:04,070 --> 00:05:00,720 combination of many many 134 00:05:04,469 --> 00:05:04,080 ccds put together at the prime focus of 135 00:05:07,590 --> 00:05:04,479 the 136 00:05:11,270 --> 00:05:07,600 rubin telescope and it is it's 137 00:05:13,110 --> 00:05:11,280 just an amazing a new detector 138 00:05:14,550 --> 00:05:13,120 okay so here are some characteristics of 139 00:05:17,909 --> 00:05:14,560 lsst cam 140 00:05:21,590 --> 00:05:17,919 first of all the field of view is seven 141 00:05:22,469 --> 00:05:21,600 full moons across okay it's 40 full 142 00:05:25,510 --> 00:05:22,479 moons across 143 00:05:28,710 --> 00:05:25,520 the whole detector that is 144 00:05:29,029 --> 00:05:28,720 huge there is a huge field of view but 145 00:05:31,909 --> 00:05:29,039 it 146 00:05:33,270 --> 00:05:31,919 also has incredible resolution as you 147 00:05:35,110 --> 00:05:33,280 can see on the right 148 00:05:36,790 --> 00:05:35,120 they've got this picture where you can't 149 00:05:37,590 --> 00:05:36,800 really see is there a golf course in 150 00:05:39,909 --> 00:05:37,600 there somewhere 151 00:05:42,310 --> 00:05:39,919 yes there is obviously and they can 152 00:05:44,310 --> 00:05:42,320 actually resolve the golf ball on the 153 00:05:45,029 --> 00:05:44,320 golf course they say they can see a golf 154 00:05:48,070 --> 00:05:45,039 ball 155 00:05:50,870 --> 00:05:48,080 from 15 miles away 156 00:05:52,550 --> 00:05:50,880 all right now it's great resolution 157 00:05:54,230 --> 00:05:52,560 especially for ground based but you know 158 00:05:55,110 --> 00:05:54,240 you know ground base does have its 159 00:05:57,430 --> 00:05:55,120 limits 160 00:05:59,270 --> 00:05:57,440 um hubble will have has four times 161 00:06:01,350 --> 00:05:59,280 better resolution than lsst 162 00:06:02,870 --> 00:06:01,360 cam but hey hubble's in space hubble 163 00:06:03,830 --> 00:06:02,880 doesn't have the atmosphere to look 164 00:06:07,029 --> 00:06:03,840 through so 165 00:06:07,749 --> 00:06:07,039 you know it's it does amazing things 166 00:06:11,270 --> 00:06:07,759 it's going to be 167 00:06:11,590 --> 00:06:11,280 huge and so this detector that i showed 168 00:06:14,390 --> 00:06:11,600 you 169 00:06:15,430 --> 00:06:14,400 is now operational and they wanted to 170 00:06:18,790 --> 00:06:15,440 test it 171 00:06:21,590 --> 00:06:18,800 so they did a um 172 00:06:22,070 --> 00:06:21,600 they did a pit hole camera to just test 173 00:06:26,950 --> 00:06:22,080 it 174 00:06:30,469 --> 00:06:26,960 and this is one of their test images 3.2 175 00:06:31,990 --> 00:06:30,479 billion pixels 3.2 gigapixels right 176 00:06:33,590 --> 00:06:32,000 you know i mean you may be impressed 177 00:06:34,950 --> 00:06:33,600 that your phone has you know 178 00:06:37,670 --> 00:06:34,960 we used to be impressed that our phones 179 00:06:41,830 --> 00:06:37,680 had one megapixel or five megapixel 180 00:06:44,870 --> 00:06:41,840 10 megapixel 40 megapixels no no 3.2 181 00:06:46,710 --> 00:06:44,880 gigapixels here okay uh this 182 00:06:48,390 --> 00:06:46,720 image that they use to test it is 183 00:06:51,430 --> 00:06:48,400 actually vera rubin 184 00:06:53,110 --> 00:06:51,440 um processing some of her data 185 00:06:54,870 --> 00:06:53,120 and they took that image they use a 186 00:06:55,990 --> 00:06:54,880 pinhole camera to spread it out across 187 00:06:58,629 --> 00:06:56,000 the entire thing 188 00:06:59,029 --> 00:06:58,639 to get a test image all right and so 189 00:07:01,430 --> 00:06:59,039 they 190 00:07:02,230 --> 00:07:01,440 now are beginning to characterize the 191 00:07:04,150 --> 00:07:02,240 detector 192 00:07:06,390 --> 00:07:04,160 they're being able to figure out all of 193 00:07:09,189 --> 00:07:06,400 the various uh details of it 194 00:07:09,749 --> 00:07:09,199 and showing that they really do have 3.2 195 00:07:12,390 --> 00:07:09,759 billion 196 00:07:13,350 --> 00:07:12,400 pixels to work with um and and this 197 00:07:15,510 --> 00:07:13,360 really you know 198 00:07:17,909 --> 00:07:15,520 it made me sort of think about wow where 199 00:07:20,870 --> 00:07:17,919 are we going to go in the next decade 200 00:07:21,990 --> 00:07:20,880 all right so um this is a hubble image 201 00:07:25,110 --> 00:07:22,000 right 202 00:07:27,510 --> 00:07:25,120 this is a hubble image of stars uh in 203 00:07:29,589 --> 00:07:27,520 the andromeda galaxy 204 00:07:31,589 --> 00:07:29,599 and there's so much detail in a hubble 205 00:07:32,230 --> 00:07:31,599 image but as you can see on the right 206 00:07:35,110 --> 00:07:32,240 that's a 207 00:07:37,430 --> 00:07:35,120 tiny tiny region in the halo of the 208 00:07:39,589 --> 00:07:37,440 andromeda galaxy okay 209 00:07:41,909 --> 00:07:39,599 for hubble to see the entire galaxy it 210 00:07:44,790 --> 00:07:41,919 would be really really difficult 211 00:07:47,270 --> 00:07:44,800 but we tried we tried we actually did 212 00:07:50,390 --> 00:07:47,280 make a hubble mosaic 213 00:07:51,909 --> 00:07:50,400 called the panchromatic hubble andromeda 214 00:07:54,950 --> 00:07:51,919 treasury program or the fat 215 00:07:57,909 --> 00:07:54,960 program and at orange square 216 00:07:58,670 --> 00:07:57,919 that's one hubble detector and we had to 217 00:08:02,230 --> 00:07:58,680 take like 218 00:08:04,950 --> 00:08:02,240 300 images to cover basically about 219 00:08:06,230 --> 00:08:04,960 one third of the andromeda galaxy as you 220 00:08:08,230 --> 00:08:06,240 see on the right 221 00:08:09,589 --> 00:08:08,240 so hubble has been able to cover that 222 00:08:12,390 --> 00:08:09,599 much 223 00:08:13,110 --> 00:08:12,400 and if you came to our previous talks 224 00:08:15,589 --> 00:08:13,120 about the 225 00:08:16,629 --> 00:08:15,599 uh the rome the what used to be called 226 00:08:19,670 --> 00:08:16,639 the w first 227 00:08:21,430 --> 00:08:19,680 uh is now the roman space telescope um 228 00:08:22,710 --> 00:08:21,440 you can see that we you know learned 229 00:08:26,869 --> 00:08:22,720 that the roman 230 00:08:29,430 --> 00:08:26,879 telescope has 18 different detectors 231 00:08:31,270 --> 00:08:29,440 spread out over a much larger region and 232 00:08:33,750 --> 00:08:31,280 that roman as shown on the right 233 00:08:34,709 --> 00:08:33,760 can do all that hubble did in its 300 or 234 00:08:37,750 --> 00:08:34,719 so pointings 235 00:08:40,230 --> 00:08:37,760 in like two or three pointings so roman 236 00:08:43,750 --> 00:08:40,240 will have a huge field of view but 237 00:08:44,630 --> 00:08:43,760 even that is not the same as what reuben 238 00:08:48,630 --> 00:08:44,640 will have 239 00:08:51,430 --> 00:08:48,640 because when we compare roman to ruben 240 00:08:53,670 --> 00:08:51,440 rubin will be able to get the entire 241 00:08:57,430 --> 00:08:53,680 andromeda galaxy in 242 00:08:57,750 --> 00:08:57,440 one image wow that's what we're gonna 243 00:08:59,829 --> 00:08:57,760 get 244 00:09:01,910 --> 00:08:59,839 we're gonna go from you know these 16 245 00:09:03,350 --> 00:09:01,920 megapixels images from hubble 246 00:09:05,350 --> 00:09:03,360 and we put them all together to make 247 00:09:06,310 --> 00:09:05,360 them even bigger but we're going to get 248 00:09:09,670 --> 00:09:06,320 3.2 249 00:09:12,870 --> 00:09:09,680 billion pixels with every image from 250 00:09:15,350 --> 00:09:12,880 the reuben telescope we're going to have 251 00:09:17,509 --> 00:09:15,360 a smorgasbord of data 252 00:09:20,070 --> 00:09:17,519 over the next couple over the next 253 00:09:24,710 --> 00:09:22,870 our second story tonight it's the 254 00:09:27,829 --> 00:09:24,720 greater pumpkin edwin 255 00:09:29,670 --> 00:09:27,839 hubble uh okay all right so 256 00:09:30,949 --> 00:09:29,680 uh some we have a lot of international 257 00:09:32,230 --> 00:09:30,959 viewers and they may not get the 258 00:09:34,630 --> 00:09:32,240 reference um 259 00:09:37,190 --> 00:09:34,640 in the united states uh we have a 260 00:09:38,870 --> 00:09:37,200 tradition of a halloween 261 00:09:40,710 --> 00:09:38,880 program called it's the great pumpkin 262 00:09:43,110 --> 00:09:40,720 charlie brown i think peanuts is 263 00:09:46,870 --> 00:09:43,120 probably worldwide but 264 00:09:50,389 --> 00:09:46,880 this tv program came out in 1966 265 00:09:52,630 --> 00:09:50,399 and our news chief decided well 266 00:09:53,829 --> 00:09:52,640 we gotta have some sort of tie-in for 267 00:09:56,389 --> 00:09:53,839 halloween 268 00:09:57,269 --> 00:09:56,399 so we found an image and it sort of 269 00:10:00,470 --> 00:09:57,279 looks like a 270 00:10:04,389 --> 00:10:00,480 pumpkin and what it and here is that 271 00:10:09,269 --> 00:10:04,399 image these are the interacting galaxies 272 00:10:11,509 --> 00:10:09,279 ngc 2292 and 2293 273 00:10:13,430 --> 00:10:11,519 what you've got going on here is those 274 00:10:15,670 --> 00:10:13,440 white eyes those are the cores of the 275 00:10:18,069 --> 00:10:15,680 galaxies that are mixing together 276 00:10:20,230 --> 00:10:18,079 and all the other material around it as 277 00:10:23,110 --> 00:10:20,240 the galaxies as they've smashed together 278 00:10:24,230 --> 00:10:23,120 and are now mixing it up and down bottom 279 00:10:25,910 --> 00:10:24,240 you see the dark 280 00:10:27,269 --> 00:10:25,920 dust lane okay that dust lane there's a 281 00:10:29,670 --> 00:10:27,279 little bit of star formation going on 282 00:10:32,870 --> 00:10:29,680 this thing that sort of forms the smile 283 00:10:34,389 --> 00:10:32,880 of the jack-o-lantern okay um and 284 00:10:35,750 --> 00:10:34,399 when they found this they said all right 285 00:10:36,389 --> 00:10:35,760 we got to do this for a halloween 286 00:10:37,990 --> 00:10:36,399 release 287 00:10:39,350 --> 00:10:38,000 and it looks sort of like a pumpkin so 288 00:10:41,190 --> 00:10:39,360 we'll call it it's they call it the 289 00:10:43,829 --> 00:10:41,200 greater pumpkin 290 00:10:44,710 --> 00:10:43,839 i actually think it looks a little bit 291 00:10:51,110 --> 00:10:44,720 more 292 00:10:53,110 --> 00:10:51,120 jack skellington from the nightmare 293 00:10:55,430 --> 00:10:53,120 before christmas 294 00:10:56,389 --> 00:10:55,440 but i guess making the jack skellington 295 00:10:59,430 --> 00:10:56,399 reference isn't the same 296 00:11:02,230 --> 00:10:59,440 although he is the pumpkin king but 297 00:11:02,949 --> 00:11:02,240 that was our halloween release uh to 298 00:11:05,590 --> 00:11:02,959 show off 299 00:11:07,110 --> 00:11:05,600 uh the interacting galaxies and how cool 300 00:11:09,110 --> 00:11:07,120 they can look 301 00:11:11,350 --> 00:11:09,120 all

clara is going to show you some 413 00:15:57,829 --> 00:15:56,800 astrophysical examples of sonophyte data 414 00:16:00,710 --> 00:15:57,839 and then 415 00:16:02,949 --> 00:16:00,720 hopefully the best part jen will walk us 416 00:16:04,710 --> 00:16:02,959 through a game show where you'll be able 417 00:16:08,949 --> 00:16:04,720 to try to test your ears 418 00:16:11,110 --> 00:16:08,959 and see if you can hear the uh sonified 419 00:16:12,710 --> 00:16:11,120 data and signals from some of these uh 420 00:16:13,990 --> 00:16:12,720 astrophysical objects that were turning 421 00:16:16,710 --> 00:16:14,000 into sound 422 00:16:17,509 --> 00:16:16,720 so before i begin one more important 423 00:16:19,749 --> 00:16:17,519 point 424 00:16:21,430 --> 00:16:19,759 this is going to feature a lot of sound 425 00:16:22,949 --> 00:16:21,440 unlike some of the other presentations 426 00:16:25,430 --> 00:16:22,959 and so if you do have 427 00:16:26,790 --> 00:16:25,440 some headphones or the ability to turn 428 00:16:28,470 --> 00:16:26,800 up your volume a little bit 429 00:16:30,949 --> 00:16:28,480 you may want to do so so you can hear 430 00:16:34,230 --> 00:16:30,959 the sounds as well as possible 431 00:16:36,949 --> 00:16:34,240 okay so i already introduced myself 432 00:16:37,590 --> 00:16:36,959 and i i'm the principal investigator and 433 00:16:47,030 --> 00:16:37,600 the 434 00:16:50,230 --> 00:16:47,040 education 435 00:16:53,350 --> 00:16:50,240 specialists 436 00:16:57,350 --> 00:16:53,360 and is a very important uh part of our 437 00:16:59,509 --> 00:16:57,360 our team here okay 438 00:17:00,710 --> 00:16:59,519 so i want to first talk about what 439 00:17:03,430 --> 00:17:00,720 sonification is 440 00:17:05,669 --> 00:17:03,440 because it's probably a term that not a 441 00:17:09,189 --> 00:17:05,679 lot of you have heard before 442 00:17:10,470 --> 00:17:09,199 and i want to start off by telling you 443 00:17:18,789 --> 00:17:10,480 what sonification 444 00:17:21,909 --> 00:17:18,799 is not is it's not sounds themselves 445 00:17:23,829 --> 00:17:21,919 so for example ocean scientists 446 00:17:25,429 --> 00:17:23,839 use something called hydrophones you see 447 00:17:27,429 --> 00:17:25,439 a picture of one on the upper left it's 448 00:17:30,150 --> 00:17:27,439 basically a very sensitive 449 00:17:31,029 --> 00:17:30,160 microphone that they put under the water 450 00:17:33,350 --> 00:17:31,039 and record 451 00:17:34,630 --> 00:17:33,360 sounds to study what what's what they 452 00:17:37,590 --> 00:17:34,640 are and what's making them 453 00:17:38,710 --> 00:17:37,600 so some examples might be a distant ship 454 00:17:41,270 --> 00:17:38,720 uh it could be 455 00:17:43,029 --> 00:17:41,280 whale songs it could be dolphin 456 00:17:44,870 --> 00:17:43,039 communication it could be undersea 457 00:17:48,549 --> 00:17:44,880 earthquakes and volcanoes 458 00:17:52,470 --> 00:17:48,559 but they are recording sounds to analyze 459 00:17:55,669 --> 00:17:52,480 in other words the sounds are the data 460 00:17:57,909 --> 00:17:55,679 when we talk about sonification what 461 00:18:01,110 --> 00:17:57,919 we're really doing is we're representing 462 00:18:01,669 --> 00:18:01,120 other types of data as sound and you're 463 00:18:04,310 --> 00:18:01,679 already 464 00:18:05,909 --> 00:18:04,320 used to this from a visual perspective 465 00:18:08,710 --> 00:18:05,919 we've all seen things like bar 466 00:18:09,510 --> 00:18:08,720 charts and pie charts and trend lines 467 00:18:12,150 --> 00:18:09,520 and 468 00:18:13,669 --> 00:18:12,160 weather maps so these are all ways that 469 00:18:16,310 --> 00:18:13,679 you can 470 00:18:17,270 --> 00:18:16,320 you know represent things like how hot 471 00:18:20,230 --> 00:18:17,280 it is outside 472 00:18:20,870 --> 00:18:20,240 or what the stock prices are doing or 473 00:18:22,549 --> 00:18:20,880 how many 474 00:18:24,230 --> 00:18:22,559 products a certain person may have 475 00:18:27,590 --> 00:18:24,240 bought in the store 476 00:18:29,669 --> 00:18:27,600 as graphs or maps 477 00:18:30,870 --> 00:18:29,679 and in our case what we're doing is 478 00:18:32,950 --> 00:18:30,880 representing 479 00:18:34,710 --> 00:18:32,960 other types of data as sound instead of 480 00:18:37,029 --> 00:18:34,720 these more visual methods 481 00:18:38,710 --> 00:18:37,039 and that is what sonification is so why 482 00:18:40,310 --> 00:18:38,720 do we want to do this why do we want to 483 00:18:42,070 --> 00:18:40,320 sonify data in the first place 484 00:18:44,310 --> 00:18:42,080 there's three main important points for 485 00:18:47,510 --> 00:18:44,320 sonifying data 486 00:18:48,789 --> 00:18:47,520 the first one is about sensitivity so it 487 00:18:51,350 --> 00:18:48,799 turns out that 488 00:18:52,870 --> 00:18:51,360 most human ears can distinguish 489 00:18:54,630 --> 00:18:52,880 something like 1300 different 490 00:18:56,950 --> 00:18:54,640 frequencies 491 00:18:58,950 --> 00:18:56,960 and the human ear is very sensitive the 492 00:19:01,190 --> 00:18:58,960 human ear can actually detect 493 00:19:02,310 --> 00:19:01,200 changes of sound at the micro second 494 00:19:05,909 --> 00:19:02,320 level that's 495 00:19:09,590 --> 00:19:05,919 one one millionth of a second 496 00:19:11,590 --> 00:19:09,600 and if you're a fan of video games or 497 00:19:13,350 --> 00:19:11,600 movies like i am 498 00:19:15,990 --> 00:19:13,360 visually you'll know that a lot of 499 00:19:18,549 --> 00:19:16,000 monitors and television screens 500 00:19:19,750 --> 00:19:18,559 typically are what we call 60 fps frames 501 00:19:21,430 --> 00:19:19,760 per second or maybe 502 00:19:23,669 --> 00:19:21,440 the top of the line ones are trying to 503 00:19:25,270 --> 00:19:23,679 go out to 120 frames per second 504 00:19:27,270 --> 00:19:25,280 but it's something like about a hundred 505 00:19:27,990 --> 00:19:27,280 frames per second and there's a reason 506 00:19:30,310 --> 00:19:28,000 why 507 00:19:32,470 --> 00:19:30,320 companies haven't bothered making you 508 00:19:33,590 --> 00:19:32,480 know thousand frame per second monitors 509 00:19:35,430 --> 00:19:33,600 or a million frame 510 00:19:37,190 --> 00:19:35,440 because the human eye just can't see it 511 00:19:39,029 --> 00:19:37,200 it turns out so 512 00:19:40,549 --> 00:19:39,039 you know visually we're sensitive to 513 00:19:41,669 --> 00:19:40,559 things that like the hundred frames per 514 00:19:43,669 --> 00:19:41,679 second level but 515 00:19:45,190 --> 00:19:43,679 audio wise our ears can detect things 516 00:19:48,230 --> 00:19:45,200 much changing at a much 517 00:19:50,070 --> 00:19:48,240 much higher resolution 518 00:19:52,070 --> 00:19:50,080 um there's another reason why uh 519 00:19:55,350 --> 00:19:52,080 sonification can be a benefit and it 520 00:19:56,310 --> 00:19:55,360 gives you a another way of analyzing 521 00:19:59,750 --> 00:19:56,320 data besides 522 00:20:01,669 --> 00:19:59,760 visually so in particular 523 00:20:03,909 --> 00:20:01,679 sonifying data allows us to do what we 524 00:20:06,230 --> 00:20:03,919 call multi-dimensional analysis 525 00:20:08,310 --> 00:20:06,240 or multi-dimensional um you know sort of 526 00:20:09,750 --> 00:20:08,320 uh preview of the data 527 00:20:10,950 --> 00:20:09,760 and what i mean by multiple dimensions 528 00:20:12,390 --> 00:20:10,960 i'll go through real quick with some 529 00:20:16,149 --> 00:20:12,400 examples so 530 00:20:19,110 --> 00:20:16,159 if i asked you to make a chart 531 00:20:20,549 --> 00:20:19,120 of a baby and how it's growing in uh in 532 00:20:22,470 --> 00:20:20,559 its weight over time 533 00:20:24,070 --> 00:20:22,480 you can do that you could measure the 534 00:20:25,750 --> 00:20:24,080 weight and make a 535 00:20:27,909 --> 00:20:25,760 chart you probably have seen these in 536 00:20:28,789 --> 00:20:27,919 doctor's offices some of you may even do 537 00:20:30,710 --> 00:20:28,799 this at home 538 00:20:33,190 --> 00:20:30,720 it's not not too hard to do we have you 539 00:20:34,950 --> 00:20:33,200 know the age on the horizontal axis we 540 00:20:36,070 --> 00:20:34,960 have the weight on the vertical axis not 541 00:20:38,630 --> 00:20:36,080 a problem 542 00:20:39,909 --> 00:20:38,640 now if i ask you though to go ahead and 543 00:20:43,029 --> 00:20:39,919 try and do that 544 00:20:44,149 --> 00:20:43,039 and i want to see how the weight and the 545 00:20:47,430 --> 00:20:44,159 height 546 00:20:48,950 --> 00:20:47,440 sort of correlate with age now we have 547 00:20:50,149 --> 00:20:48,960 to make a three-dimensional plot and 548 00:20:52,149 --> 00:20:50,159 that's a little harder to do 549 00:20:53,909 --> 00:20:52,159 but with computer graphics we're able to 550 00:20:56,070 --> 00:20:53,919 do that 551 00:20:56,950 --> 00:20:56,080 but if i then go ahead and ask you to 552 00:20:59,110 --> 00:20:56,960 now 553 00:21:01,029 --> 00:20:59,120 see how the weight and the height and 554 00:21:03,110 --> 00:21:01,039 the temperature and the o2 level and 555 00:21:04,230 --> 00:21:03,120 your vitamin d's and your blood pressure 556 00:21:07,029 --> 00:21:04,240 and all these things 557 00:21:08,710 --> 00:21:07,039 are all correlated together we run out 558 00:21:10,630 --> 00:21:08,720 of options right 559 00:21:12,230 --> 00:21:10,640 because we can only visualize a 560 00:21:15,110 --> 00:21:12,240 three-dimensional space 561 00:21:16,230 --> 00:21:15,120 on a 2d surface like a screen or a piece 562 00:21:18,390 --> 00:21:16,240 of paper 563 00:21:19,430 --> 00:21:18,400 so there are tricks you can try to do 564 00:21:21,590 --> 00:21:19,440 where you represent 565 00:21:24,070 --> 00:21:21,600 all these different variables using 566 00:21:25,990 --> 00:21:24,080 different visual cues like different 567 00:21:29,029 --> 00:21:26,000 colors for one thing and different 568 00:21:30,789 --> 00:21:29,039 sizes for another thing and different 569 00:21:33,270 --> 00:21:30,799 you know whether it's filled in or not 570 00:21:35,990 --> 00:21:33,280 and you play with the x and y and the z 571 00:21:36,789 --> 00:21:36,000 axes and but pretty quickly the chart 572 00:21:39,750 --> 00:21:36,799 becomes 573 00:21:41,510 --> 00:21:39,760 too complicated to see a lot of detail 574 00:21:43,430 --> 00:21:41,520 one of the cool things about sound is 575 00:21:46,149 --> 00:21:43,440 that it's inherently multi-dimensional 576 00:21:48,950 --> 00:21:46,159 and if anybody has played around with 3d 577 00:21:50,310 --> 00:21:48,960 sound or have surround sound systems 578 00:21:53,510 --> 00:21:50,320 you kind of know this pretty well 579 00:21:56,230 --> 00:21:53,520 because you have not only the concept of 580 00:21:57,029 --> 00:21:56,240 if you have good speakers left and right 581 00:21:59,510 --> 00:21:57,039 up and down 582 00:22:01,430 --> 00:21:59,520 front and back but also things like the 583 00:22:03,590 --> 00:22:01,440 volume of the sound can be changed and 584 00:22:05,350 --> 00:22:03,600 the type of sound itself can be changed 585 00:22:06,789 --> 00:22:05,360 whether it's different instruments or 586 00:22:08,470 --> 00:22:06,799 you can change different pitches and 587 00:22:10,710 --> 00:22:08,480 different tones and overtones 588 00:22:12,149 --> 00:22:10,720 and we immediately have all these extra 589 00:22:13,990 --> 00:22:12,159 things to be able to 590 00:22:15,590 --> 00:22:14,000 assign to variables to be able to 591 00:22:17,029 --> 00:22:15,600 explore a data set from an audio 592 00:22:19,350 --> 00:22:17,039 perspective 593 00:22:21,110 --> 00:22:19,360 and the third and most important reason 594 00:22:23,029 --> 00:22:21,120 is accessibility 595 00:22:24,470 --> 00:22:23,039 so for people who are blind or low 596 00:22:26,710 --> 00:22:24,480 vision 597 00:22:28,549 --> 00:22:26,720 the only way that they can really um you 598 00:22:30,549 --> 00:22:28,559 know interact with data is primarily 599 00:22:33,270 --> 00:22:30,559 through audio or touch 600 00:22:35,350 --> 00:22:33,280 and astronomy in particular as well as 601 00:22:36,630 --> 00:22:35,360 science in general is oftentimes such a 602 00:22:42,470 --> 00:22:36,640 visual 603 00:22:44,470 --> 00:22:42,480 um where you know images and and uh 604 00:22:47,590 --> 00:22:44,480 graphs and all these things are 605 00:22:51,029 --> 00:22:47,600 are dominant in in in our field and so 606 00:22:53,350 --> 00:22:51,039 providing data through a sonified format 607 00:22:54,470 --> 00:22:53,360 um increases the accessibility of data 608 00:22:56,630 --> 00:22:54,480 to these um 609 00:22:58,230 --> 00:22:56,640 to the to community scientists who are 610 00:23:00,310 --> 00:22:58,240 interested in participating 611 00:23:02,470 --> 00:23:00,320 in in things like citizen science 612 00:23:05,830 --> 00:23:02,480 projects and also for those who want to 613 00:23:08,710 --> 00:23:05,840 do astronomy as a career so 614 00:23:09,590 --> 00:23:08,720 um those are our motivations uh for the 615 00:23:11,669 --> 00:23:09,600 project 616 00:23:13,430 --> 00:23:11,679 and i'm going to take you through a 617 00:23:15,190 --> 00:23:13,440 couple simple examples 618 00:23:16,789 --> 00:23:15,200 uh using shapes because shapes are 619 00:23:18,789 --> 00:23:16,799 something we all understand and then i'm 620 00:23:21,190 --> 00:23:18,799 going to pass it off to claire who 621 00:23:21,990 --> 00:23:21,200 get into this astrophysics part so this 622 00:23:23,430 --> 00:23:22,000 is sort of to 623 00:23:25,510 --> 00:23:23,440 calibrate our understanding of what we 624 00:23:27,830 --> 00:23:25,520 mean by sonification and as a quick note 625 00:23:29,350 --> 00:23:27,840 because of the video and audio lag there 626 00:23:30,630 --> 00:23:29,360 might be a little bit of a difference 627 00:23:32,390 --> 00:23:30,640 between the sound you're hearing and 628 00:23:33,350 --> 00:23:32,400 where the red marker is but don't worry 629 00:23:34,789 --> 00:23:33,360 about it 630 00:23:37,029 --> 00:23:34,799 if you're curious you can always go to 631 00:23:37,830 --> 00:23:37,039 our home page and click on the youtube 632 00:23:40,230 --> 00:23:37,840 videos 633 00:23:41,350 --> 00:23:40,240 for for some of these and and get a good 634 00:23:43,510 --> 00:23:41,360 sync but 635 00:23:44,950 --> 00:23:43,520 we'll continue so to get everybody on 636 00:23:45,990 --> 00:23:44,960 the zero point what i'm going to play 637 00:23:48,870 --> 00:23:46,000 right now 638 00:23:49,590 --> 00:23:48,880 is the simplest possible use case which 639 00:23:58,630 --> 00:23:49,600 is 640 00:24:02,070 --> 00:24:01,269 constant steady tone because we have 641 00:24:04,789 --> 00:24:02,080 constant 642 00:24:05,909 --> 00:24:04,799 steady shape okay that's pretty pretty 643 00:24:07,590 --> 00:24:05,919 good to understand 644 00:24:09,350 --> 00:24:07,600 let's change it a little bit now and 645 00:24:10,070 --> 00:24:09,360 what we're going to do is we're going to 646 00:24:13,669 --> 00:24:10,080 draw 647 00:24:14,630 --> 00:24:13,679 a diagonal straight line roughly at a 45 648 00:24:16,470 --> 00:24:14,640 degree angle 649 00:24:18,480 --> 00:24:16,480 and we'll see what happens when we 650 00:24:25,110 --> 00:24:18,490 solidify the shape 651 00:24:28,630 --> 00:24:27,190 all right so now you can really hear 652 00:24:30,630 --> 00:24:28,640 that things are changing 653 00:24:32,149 --> 00:24:30,640 this just like the line or the shape 654 00:24:34,230 --> 00:24:32,159 itself is changing the 655 00:24:35,669 --> 00:24:34,240 the sound you're hearing in pitch is 656 00:24:37,990 --> 00:24:35,679 going from low and 657 00:24:39,669 --> 00:24:38,000 constantly going up to a higher and 658 00:24:41,190 --> 00:24:39,679 higher pitch at the end 659 00:24:43,110 --> 00:24:41,200 now let's look at what we might expect 660 00:24:44,789 --> 00:24:43,120 for the top of a triangle 661 00:24:46,230 --> 00:24:44,799 and i bet you you all can figure out 662 00:24:48,340 --> 00:24:46,240 what might what this might sound like 663 00:24:54,310 --> 00:24:48,350 let's go ahead and listen to this too 664 00:24:57,350 --> 00:24:56,870 all right so that sounds just like we 665 00:24:59,350 --> 00:24:57,360 might 666 00:25:01,190 --> 00:24:59,360 expect it based on either the shape or 667 00:25:03,669 --> 00:25:01,200 or the graph 668 00:25:05,590 --> 00:25:03,679 we have essentially two diagonal lines 669 00:25:07,590 --> 00:25:05,600 one going up one going down and 670 00:25:10,070 --> 00:25:07,600 just like the shape itself the sound is 671 00:25:12,549 --> 00:25:10,080 literally rising and falling 672 00:25:14,149 --> 00:25:12,559 constantly and pretty sharp so the very 673 00:25:15,830 --> 00:25:14,159 last thing i want to present 674 00:25:18,350 --> 00:25:15,840 is what the top of a circle might sound 675 00:25:24,310 --> 00:25:18,360 like let's go ahead and listen to that 676 00:25:27,430 --> 00:25:24,320 [Music] 677 00:25:28,149 --> 00:25:27,440 so just like the triangle and just like 678 00:25:30,710 --> 00:25:28,159 the shape 679 00:25:32,549 --> 00:25:30,720 the circle is also rising and falling 680 00:25:34,230 --> 00:25:32,559 but the shape itself if you think about 681 00:25:36,789 --> 00:25:34,240 a triangle compared to a circle 682 00:25:37,350 --> 00:25:36,799 it's a much more gradual and constant 683 00:25:41,430 --> 00:25:37,360 change 684 00:25:43,350 --> 00:25:41,440 one side of the circle to the top 685 00:25:45,430 --> 00:25:43,360 and to the other side of the circle and 686 00:25:48,230 --> 00:25:45,440 just like that you should have heard 687 00:25:49,350 --> 00:25:48,240 the sound compared to the triangle also 688 00:25:51,269 --> 00:25:49,360 change in pitch 689 00:25:53,909 --> 00:25:51,279 much more gradually until it reached the 690 00:25:56,070 --> 00:25:53,919 top and then gradually fall down 691 00:25:58,230 --> 00:25:56,080 as opposed to a triangle which had much 692 00:26:00,070 --> 00:25:58,240 quicker changes in pitch when it 693 00:26:01,510 --> 00:26:00,080 got to the top and then went back down 694 00:26:03,350 --> 00:26:01,520 again so 695 00:26:05,909 --> 00:26:03,360 this is just to show you what we mean by 696 00:26:06,870 --> 00:26:05,919 sonifying data in this case it's shapes 697 00:26:08,950 --> 00:26:06,880 but for the next part of the 698 00:26:09,669 --> 00:26:08,960 presentation clara is going to go 699 00:26:11,269 --> 00:26:09,679 through 700 00:26:13,110 --> 00:26:11,279 some examples of how we take 701 00:26:13,909 --> 00:26:13,120 astronomical data this is real 702 00:26:17,430 --> 00:26:13,919 measurements 703 00:26:20,230 --> 00:26:17,440 brightness of objects 704 00:26:21,269 --> 00:26:20,240 and will translate those measurements 705 00:26:25,269 --> 00:26:21,279 into sound 706 00:26:27,510 --> 00:26:25,279 claire over to you 707 00:26:29,669 --> 00:26:27,520 hi everyone um so i'm going to talk 708 00:26:31,510 --> 00:26:29,679 about as scott said 709 00:26:33,110 --> 00:26:31,520 applying the techniques that we use to 710 00:26:34,870 --> 00:26:33,120 sonify those simple 711 00:26:37,269 --> 00:26:34,880 shapes and applying that to real 712 00:26:41,190 --> 00:26:37,279 astronomical data 713 00:26:43,110 --> 00:26:41,200 whoops so to start off with 714 00:26:44,230 --> 00:26:43,120 the kind of data that we're sonifying is 715 00:26:46,789 --> 00:26:44,240 called a light curve 716 00:26:48,230 --> 00:26:46,799 so the very introduction um there were 717 00:26:51,029 --> 00:26:48,240 all these beautiful pictures 718 00:26:52,230 --> 00:26:51,039 of galaxies and stars and even a 719 00:26:54,710 --> 00:26:52,240 birthday cake 720 00:26:56,230 --> 00:26:54,720 and there and those are all images this 721 00:26:58,390 --> 00:26:56,240 is a different kind of data 722 00:27:01,190 --> 00:26:58,400 it's fundamentally a record of how 723 00:27:03,430 --> 00:27:01,200 bright an object is a star or a galaxy 724 00:27:04,710 --> 00:27:03,440 or whatever astronomical object we're 725 00:27:08,390 --> 00:27:04,720 looking at is 726 00:27:12,470 --> 00:27:08,400 over time space telescope 727 00:27:14,470 --> 00:27:12,480 holds uh data from two very important 728 00:27:16,070 --> 00:27:14,480 space telescope missions that produce 729 00:27:18,230 --> 00:27:16,080 light curves they're tess 730 00:27:20,870 --> 00:27:18,240 and kepler and both of them their 731 00:27:23,830 --> 00:27:20,880 primary purpose has been 732 00:27:25,830 --> 00:27:23,840 to search for exoplanets planets that 733 00:27:29,029 --> 00:27:25,840 orbit stars other than the sun 734 00:27:31,750 --> 00:27:29,039 however they both produce a lot of 735 00:27:33,990 --> 00:27:31,760 data about a lot of stars and so we can 736 00:27:35,750 --> 00:27:34,000 use that data to look at a lot of 737 00:27:38,789 --> 00:27:35,760 different astrophysical phenomena 738 00:27:41,269 --> 00:27:38,799 not just exoplanets 739 00:27:42,149 --> 00:27:41,279 so the way we typically visualize light 740 00:27:46,230 --> 00:27:42,159 curves 741 00:27:48,310 --> 00:27:46,240 is as a line graph because it is 742 00:27:49,430 --> 00:27:48,320 a measure of the brightness of star over 743 00:27:51,510 --> 00:27:49,440 time we 744 00:27:53,990 --> 00:27:51,520 you you really what you have is a data 745 00:27:56,870 --> 00:27:54,000 table that has two columns one is time 746 00:27:59,669 --> 00:27:56,880 and one is how bright the star is so we 747 00:28:02,149 --> 00:27:59,679 can plot that with time on the x-axis 748 00:28:03,430 --> 00:28:02,159 and light on the y-axis and then we can 749 00:28:05,990 --> 00:28:03,440 just look at 750 00:28:07,909 --> 00:28:06,000 the line and see when it's higher the 751 00:28:11,430 --> 00:28:07,919 star is brighter and when it's dimmer 752 00:28:13,830 --> 00:28:11,440 the when it's lower the star is dimmer 753 00:28:16,710 --> 00:28:13,840 so when we translate that into sound we 754 00:28:18,470 --> 00:28:16,720 keep time as time we simply scale it to 755 00:28:19,350 --> 00:28:18,480 be something that's reasonable to listen 756 00:28:21,350 --> 00:28:19,360 to 757 00:28:22,630 --> 00:28:21,360 and then instead of translating how 758 00:28:26,549 --> 00:28:22,640 bright the star is 759 00:28:27,750 --> 00:28:26,559 into the place on the plot we translate 760 00:28:29,830 --> 00:28:27,760 it into the pitch 761 00:28:31,590 --> 00:28:29,840 so just like scott showed the higher the 762 00:28:32,710 --> 00:28:31,600 pitch the more light and the lower they 763 00:28:35,830 --> 00:28:32,720 picked the less light 764 00:28:38,470 --> 00:28:35,840 so this is a real piece of data from 765 00:28:39,590 --> 00:28:38,480 one star that came from the kepler light 766 00:28:41,669 --> 00:28:39,600 curve 767 00:28:44,770 --> 00:28:41,679 kepler space telescope and this is how 768 00:28:50,480 --> 00:28:44,780 it sounds 769 00:28:54,230 --> 00:28:50,490 [Music] 770 00:28:58,230 --> 00:28:54,240 [Laughter] 771 00:29:02,389 --> 00:28:58,240 so this is pretty similar 772 00:29:03,830 --> 00:29:02,399 to to what scott was showing but it's a 773 00:29:05,430 --> 00:29:03,840 little more complicated because this 774 00:29:06,630 --> 00:29:05,440 isn't a simple shape this is the light 775 00:29:09,590 --> 00:29:06,640 from a star 776 00:29:11,350 --> 00:29:09,600 um so we can use this then to look at a 777 00:29:13,750 --> 00:29:11,360 lot of different things 778 00:29:14,870 --> 00:29:13,760 so even though i said that we can look 779 00:29:16,389 --> 00:29:14,880 at a lot of different things we're going 780 00:29:17,590 --> 00:29:16,399 to start with exoplanets because 781 00:29:21,029 --> 00:29:17,600 exoplanets 782 00:29:22,789 --> 00:29:21,039 these telescopes 783 00:29:24,470 --> 00:29:22,799 were put into orbit and the reason that 784 00:29:27,909 --> 00:29:24,480 they were designed to 785 00:29:28,470 --> 00:29:27,919 return light curves so when you're 786 00:29:31,510 --> 00:29:28,480 looking 787 00:29:32,950 --> 00:29:31,520 for exoplanets in light curves what 788 00:29:36,389 --> 00:29:32,960 you're looking for 789 00:29:38,149 --> 00:29:36,399 is what we call a transit which is when 790 00:29:40,470 --> 00:29:38,159 a planet 791 00:29:41,909 --> 00:29:40,480 crosses between the viewer in this case 792 00:29:44,310 --> 00:29:41,919 officer the telescope 793 00:29:46,630 --> 00:29:44,320 and the star that it's orbiting so the 794 00:29:48,789 --> 00:29:46,640 star is putting out an amount of light 795 00:29:49,669 --> 00:29:48,799 and then some of that light is blocked 796 00:29:52,149 --> 00:29:49,679 as the 797 00:29:53,669 --> 00:29:52,159 planet transits across it and then when 798 00:29:55,830 --> 00:29:53,679 it finishes translating across 799 00:29:57,510 --> 00:29:55,840 and continues its orbit around the back 800 00:29:58,630 --> 00:29:57,520 the light from the star is not blocked 801 00:29:59,590 --> 00:29:58,640 again 802 00:30:01,510 --> 00:29:59,600 so we're looking for these 803 00:30:04,070 --> 00:30:01,520 characteristic dips in the light curve 804 00:30:06,870 --> 00:30:04,080 that occur at regular intervals 805 00:30:09,510 --> 00:30:06,880 as the star continues around and around 806 00:30:11,990 --> 00:30:09,520 its planet 807 00:30:13,029 --> 00:30:12,000 so we've discovered that there are a lot 808 00:30:15,430 --> 00:30:13,039 of planets 809 00:30:17,430 --> 00:30:15,440 outside of our own solar system just a 810 00:30:19,669 --> 00:30:17,440 lot of all different kinds 811 00:30:21,269 --> 00:30:19,679 and many that are just very very foreign 812 00:30:23,590 --> 00:30:21,279 to anything that we have 813 00:30:25,190 --> 00:30:23,600 in our solar system and one of the ones 814 00:30:27,590 --> 00:30:25,200 that i think is particularly interesting 815 00:30:29,350 --> 00:30:27,600 are what are called hot jupiters 816 00:30:31,510 --> 00:30:29,360 so probably some of you have guessed 817 00:30:34,230 --> 00:30:31,520 that these are jupiter-sized planets 818 00:30:35,430 --> 00:30:34,240 but unlike our jupiter with orbits 819 00:30:37,110 --> 00:30:35,440 pretty far out 820 00:30:39,830 --> 00:30:37,120 from its sun certainly farther out than 821 00:30:42,549 --> 00:30:39,840 we on earth do hot jupiters orbit 822 00:30:43,190 --> 00:30:42,559 incredibly close to their host star like 823 00:30:44,870 --> 00:30:43,200 closer 824 00:30:46,630 --> 00:30:44,880 than the orbit of mercury if they were 825 00:30:49,990 --> 00:30:46,640 in our solar system 826 00:30:53,669 --> 00:30:50,000 and jupiter our jupiter is made up of 827 00:30:55,350 --> 00:30:53,679 a lot of gas and so these jupiters are 828 00:30:57,990 --> 00:30:55,360 are like that too their composition is 829 00:31:00,870 --> 00:30:58,000 more like jupiter so they're just huge 830 00:31:03,190 --> 00:31:00,880 and puffy and hot and very very close to 831 00:31:06,230 --> 00:31:03,200 their host star 832 00:31:08,149 --> 00:31:06,240 so kepler-12b um is a planet that was 833 00:31:09,269 --> 00:31:08,159 observed unsurprisingly by the kepler 834 00:31:11,190 --> 00:31:09,279 space telescope 835 00:31:13,029 --> 00:31:11,200 and it's a hot jupiter that is orbiting 836 00:31:14,310 --> 00:31:13,039 a star that is very similar to our own 837 00:31:16,230 --> 00:31:14,320 sun 838 00:31:17,990 --> 00:31:16,240 but obviously its system is very 839 00:31:19,990 --> 00:31:18,000 different from ours it has a period of 840 00:31:20,549 --> 00:31:20,000 just four and a half days so that means 841 00:31:23,269 --> 00:31:20,559 the 842 00:31:25,509 --> 00:31:23,279 equivalent of a year on this planet is 843 00:31:27,190 --> 00:31:25,519 just four and a half days 844 00:31:29,190 --> 00:31:27,200 and knowing that we can also get a sense 845 00:31:29,990 --> 00:31:29,200 of the time scale of this sonification 846 00:31:35,669 --> 00:31:30,000 here 847 00:31:36,149 --> 00:31:35,679 this flat flattish line across the top 848 00:31:40,950 --> 00:31:36,159 is 849 00:31:43,830 --> 00:31:40,960 in these dips 850 00:31:45,669 --> 00:31:43,840 by the transiting exoplanet and so the 851 00:31:48,149 --> 00:31:45,679 distance between these 852 00:31:51,509 --> 00:31:48,159 is going to be the length of the orbit 853 00:31:54,070 --> 00:31:51,519 of this planet so this is 4.5 days 854 00:31:55,029 --> 00:31:54,080 so we've sped it up so that it will 855 00:31:57,430 --> 00:31:55,039 actually play 856 00:31:59,029 --> 00:31:57,440 in just a couple of seconds but that 857 00:32:12,230 --> 00:31:59,039 gives us a sense of scale 858 00:32:16,070 --> 00:32:14,870 so we can hear this constant pitch that 859 00:32:19,110 --> 00:32:16,080 is the light from the sun 860 00:32:21,830 --> 00:32:19,120 interrupted by these lower 861 00:32:23,830 --> 00:32:21,840 cords that are the transit of the planet 862 00:32:26,789 --> 00:32:23,840 periodically 863 00:32:27,430 --> 00:32:26,799 and this and this planet but because it 864 00:32:29,669 --> 00:32:27,440 is so 865 00:32:31,269 --> 00:32:29,679 big and so close it blocks out a lot of 866 00:32:34,630 --> 00:32:31,279 the light from its star so these dips 867 00:32:38,630 --> 00:32:36,470 the second type of star i'm going to 868 00:32:40,389 --> 00:32:38,640 talk about is called a heartbeat star 869 00:32:42,310 --> 00:32:40,399 and it's it's called a heartbeat star 870 00:32:45,590 --> 00:32:42,320 but it's actually a binary star 871 00:32:47,830 --> 00:32:45,600 system and it consists of one star 872 00:32:49,830 --> 00:32:47,840 orbiting a larger star in an elliptical 873 00:32:52,070 --> 00:32:49,840 orbit and so what that means 874 00:32:52,950 --> 00:32:52,080 is that there's a large star and a 875 00:32:54,149 --> 00:32:52,960 smaller star 876 00:32:56,630 --> 00:32:54,159 is orbiting in such a way where 877 00:32:58,789 --> 00:32:56,640 sometimes it's very close to that 878 00:33:00,070 --> 00:32:58,799 large star and sometimes it's very far 879 00:33:02,950 --> 00:33:00,080 away 880 00:33:03,590 --> 00:33:02,960 and what what the result of this is the 881 00:33:07,269 --> 00:33:03,600 while 882 00:33:08,950 --> 00:33:07,279 the smaller star is is much smaller 883 00:33:11,590 --> 00:33:08,960 it isn't as small as a planet and it 884 00:33:13,830 --> 00:33:11,600 still exerts quite a 885 00:33:15,110 --> 00:33:13,840 it exerts a gravitational pull on the 886 00:33:17,350 --> 00:33:15,120 larger star 887 00:33:19,190 --> 00:33:17,360 enough to destabilize the star and 888 00:33:21,190 --> 00:33:19,200 essentially cause it to ring like a bell 889 00:33:22,310 --> 00:33:21,200 so there's these ongoing vibrations in 890 00:33:24,070 --> 00:33:22,320 the larger star 891 00:33:25,669 --> 00:33:24,080 and they are stronger when the stars are 892 00:33:27,750 --> 00:33:25,679 closer together and 893 00:33:28,870 --> 00:33:27,760 weaker when the stars are farther away 894 00:33:31,110 --> 00:33:28,880 and the result of this 895 00:33:33,750 --> 00:33:31,120 is that the light curve when plotted 896 00:33:36,310 --> 00:33:33,760 looks a little bit like an ekg 897 00:33:38,070 --> 00:33:36,320 with the up and down um and so this is 898 00:33:40,950 --> 00:33:38,080 why it got the name heartbeat star 899 00:33:42,230 --> 00:33:40,960 even though it's actually two stars and 900 00:33:44,630 --> 00:33:42,240 so this is the plot 901 00:33:46,230 --> 00:33:44,640 and we can see that behavior these these 902 00:33:47,990 --> 00:33:46,240 are the the 903 00:33:49,430 --> 00:33:48,000 the small up and downs that are the 904 00:33:51,269 --> 00:33:49,440 vibrations 905 00:33:53,590 --> 00:33:51,279 that are induced in the large star and 906 00:33:55,350 --> 00:33:53,600 they get larger and smaller and larger 907 00:33:57,909 --> 00:33:55,360 and smaller on a fixed 908 00:33:59,029 --> 00:33:57,919 on a fixed period and that is the orbit 909 00:34:02,230 --> 00:33:59,039 of the star 910 00:34:04,310 --> 00:34:02,240 and so if we solidify this um such 911 00:34:05,990 --> 00:34:04,320 such that we're scanning across it very 912 00:34:09,030 --> 00:34:06,000 quickly we can hear that large 913 00:34:13,589 --> 00:34:09,040 scale orbiting pattern very easily 914 00:34:18,149 --> 00:34:15,990 so here it does really feel in some ways 915 00:34:21,109 --> 00:34:18,159 like a beading pattern so you can sort 916 00:34:24,149 --> 00:34:21,119 of feel that heartbeat 917 00:34:26,069 --> 00:34:24,159 but you can't really distinguish the 918 00:34:27,829 --> 00:34:26,079 smaller scale changes you just know that 919 00:34:29,510 --> 00:34:27,839 you're getting a large chord and then 920 00:34:31,430 --> 00:34:29,520 just a few notes and then a large chord 921 00:34:31,990 --> 00:34:31,440 so you can hear that but you can't hear 922 00:34:35,430 --> 00:34:32,000 the 923 00:34:37,990 --> 00:34:35,440 again but this time 924 00:34:50,790 --> 00:34:38,000 scan across much slower we can start to 925 00:34:55,909 --> 00:34:53,750 so now it's a little bit harder to 926 00:34:57,910 --> 00:34:55,919 detect the larger scale pattern because 927 00:34:59,670 --> 00:34:57,920 it's so much slower but we can really 928 00:35:01,589 --> 00:34:59,680 hear those vibrations 929 00:35:02,710 --> 00:35:01,599 and so the way you sonify a piece of 930 00:35:04,550 --> 00:35:02,720 data just like 931 00:35:06,790 --> 00:35:04,560 you make changes in how you visualize a 932 00:35:08,470 --> 00:35:06,800 piece of data is based on 933 00:35:10,470 --> 00:35:08,480 what you're trying to explore what 934 00:35:15,990 --> 00:35:10,480 features you're looking for 935 00:35:17,589 --> 00:35:16,000 and what information you want to get out 936 00:35:19,589 --> 00:35:17,599 so the next type of star we're going to 937 00:35:21,589 --> 00:35:19,599 look at is a pulsating star and so this 938 00:35:22,550 --> 00:35:21,599 is a single star and it's a next star 939 00:35:25,270 --> 00:35:22,560 that expands 940 00:35:26,710 --> 00:35:25,280 and contracts regularly these stars tend 941 00:35:30,550 --> 00:35:26,720 to be very hot 942 00:35:33,589 --> 00:35:30,560 um they are unstable um so 943 00:35:34,550 --> 00:35:33,599 inside the star in with all of the hot 944 00:35:36,470 --> 00:35:34,560 plasma 945 00:35:38,069 --> 00:35:36,480 there's some instabilities so so that 946 00:35:39,910 --> 00:35:38,079 the star will puff off it will get 947 00:35:42,550 --> 00:35:39,920 hotter and puff up 948 00:35:43,990 --> 00:35:42,560 and then it won't be able to sustain 949 00:35:45,349 --> 00:35:44,000 itself and so 950 00:35:46,950 --> 00:35:45,359 gravity will start to take over and 951 00:35:47,990 --> 00:35:46,960 it'll collapse back and at a certain 952 00:35:51,109 --> 00:35:48,000 point 953 00:35:53,670 --> 00:35:51,119 the the compression of the plasma 954 00:35:54,310 --> 00:35:53,680 will will cause it to stop and heat and 955 00:35:56,150 --> 00:35:54,320 heat up more 956 00:35:57,670 --> 00:35:56,160 and expand again and this just goes back 957 00:35:59,510 --> 00:35:57,680 and forth and back and forth 958 00:36:01,589 --> 00:35:59,520 and so you have this in and out motion 959 00:36:04,390 --> 00:36:01,599 and that 960 00:36:05,109 --> 00:36:04,400 and and so that physical motion of the 961 00:36:07,270 --> 00:36:05,119 star 962 00:36:08,470 --> 00:36:07,280 translates to a corresponding change in 963 00:36:12,310 --> 00:36:08,480 the brightness 964 00:36:12,630 --> 00:36:12,320 um that so in this case when we solidify 965 00:36:15,430 --> 00:36:12,640 it 966 00:36:16,470 --> 00:36:15,440 we're sort of inferring from an infer so 967 00:36:19,190 --> 00:36:16,480 we're we're using 968 00:36:21,270 --> 00:36:19,200 sound to hear the differences in light 969 00:36:21,589 --> 00:36:21,280 which is telling us about the changes in 970 00:36:27,670 --> 00:36:21,599 the 971 00:36:28,470 --> 00:36:27,680 happen over short periods of a couple 972 00:36:31,670 --> 00:36:28,480 two 973 00:36:34,390 --> 00:36:31,680 days to maybe a little over a week 974 00:36:36,150 --> 00:36:34,400 and they're very regular so this is a 975 00:36:38,069 --> 00:36:36,160 heartbeat star this is what's called a 976 00:36:40,790 --> 00:36:38,079 delta scooty so it's a young 977 00:36:42,950 --> 00:36:40,800 hot pulsating star so it's very young 978 00:36:53,589 --> 00:36:42,960 and it's very hot and it's wobbling 979 00:36:59,270 --> 00:36:56,950 and it just keeps going we have 980 00:37:00,550 --> 00:36:59,280 years of this data and it just keeps 981 00:37:02,950 --> 00:37:00,560 going because on 982 00:37:05,109 --> 00:37:02,960 on the scale at which we're taking data 983 00:37:09,670 --> 00:37:05,119 for these space telescopes 984 00:37:11,670 --> 00:37:09,680 um uh 985 00:37:13,829 --> 00:37:11,680 it is very constant even though it's an 986 00:37:15,109 --> 00:37:13,839 unstable star it's unstable in a very 987 00:37:18,310 --> 00:37:15,119 stable way 988 00:37:20,230 --> 00:37:18,320 it's it's it's um going out to the same 989 00:37:21,190 --> 00:37:20,240 radius and shrinking to the same radius 990 00:37:23,589 --> 00:37:21,200 and continuing 991 00:37:24,870 --> 00:37:23,599 but on astronomical scales these stars 992 00:37:28,710 --> 00:37:24,880 are unstable 993 00:37:30,710 --> 00:37:28,720 and so they're short-lived and and 994 00:37:32,470 --> 00:37:30,720 and are and are some of the more active 995 00:37:33,510 --> 00:37:32,480 stars in terms of moving around their 996 00:37:35,349 --> 00:37:33,520 characteristics 997 00:37:37,349 --> 00:37:35,359 but that's still on an astronomical 998 00:37:39,349 --> 00:37:37,359 scale so it's much longer than a scale 999 00:37:41,990 --> 00:37:39,359 that we can see over the course of even 1000 00:37:44,390 --> 00:37:42,000 a relatively long 1001 00:37:49,589 --> 00:37:44,400 telescope mission like kepler which took 1002 00:37:52,950 --> 00:37:51,349 uh and so the last astronomical 1003 00:37:54,710 --> 00:37:52,960 phenomena i'm going to talk about 1004 00:37:56,390 --> 00:37:54,720 is different than the ones i've talked 1005 00:37:58,790 --> 00:37:56,400 to all of the ones i've talked about 1006 00:38:02,390 --> 00:37:58,800 before that all have some sort of 1007 00:38:04,310 --> 00:38:02,400 regular uh period with what 1008 00:38:06,470 --> 00:38:04,320 whether it's because there's a planet 1009 00:38:07,109 --> 00:38:06,480 rotating a star a star rotating another 1010 00:38:15,829 --> 00:38:07,119 star 1011 00:38:18,950 --> 00:38:15,839 the stellar equivalent of solar flares 1012 00:38:19,829 --> 00:38:18,960 and they're a result of buildups of 1013 00:38:22,950 --> 00:38:19,839 energy 1014 00:38:25,430 --> 00:38:22,960 in the upper layers of the star and 1015 00:38:27,430 --> 00:38:25,440 the atmosphere and they build up slowly 1016 00:38:30,550 --> 00:38:27,440 over time and when a certain critical 1017 00:38:32,950 --> 00:38:30,560 amount of energy is is reached 1018 00:38:34,630 --> 00:38:32,960 it needs to go somewhere and so it 1019 00:38:36,870 --> 00:38:34,640 explodes 1020 00:38:37,829 --> 00:38:36,880 very quickly in a burst of light and 1021 00:38:40,870 --> 00:38:37,839 energy 1022 00:38:42,790 --> 00:38:40,880 and then collapses back into the 1023 00:38:44,630 --> 00:38:42,800 star as it was before the explosion and 1024 00:38:48,150 --> 00:38:44,640 these aren't predictable 1025 00:38:50,710 --> 00:38:48,160 um we have we know basically 1026 00:38:52,390 --> 00:38:50,720 how many we expect to see of what energy 1027 00:38:54,310 --> 00:38:52,400 over a long period of time but we don't 1028 00:38:55,349 --> 00:38:54,320 know what any individual one is going to 1029 00:38:57,109 --> 00:38:55,359 happen 1030 00:38:58,870 --> 00:38:57,119 so instead of seeing something periodic 1031 00:39:01,030 --> 00:38:58,880 we see something more like this 1032 00:39:02,310 --> 00:39:01,040 where you have this baseline starlight 1033 00:39:04,550 --> 00:39:02,320 and then there's this 1034 00:39:07,109 --> 00:39:04,560 sudden sharp peak that's the flare that 1035 00:39:09,190 --> 00:39:07,119 then more gradually returns back to that 1036 00:39:11,829 --> 00:39:09,200 baseline 1037 00:39:13,270 --> 00:39:11,839 and so here's a real flare from a space 1038 00:39:15,589 --> 00:39:13,280 telescope 1039 00:39:19,770 --> 00:39:15,599 and this is it sounds really quite 1040 00:39:25,190 --> 00:39:23,430 [Music] 1041 00:39:27,349 --> 00:39:25,200 so this is a great flare because you can 1042 00:39:28,950 --> 00:39:27,359 hear this sharp explosion 1043 00:39:31,109 --> 00:39:28,960 there's a sharp peak and then it and 1044 00:39:32,870 --> 00:39:31,119 then it gradually returns in fact at the 1045 00:39:34,470 --> 00:39:32,880 end of this set of data it has not 1046 00:39:38,390 --> 00:39:34,480 returned all the way back 1047 00:39:40,390 --> 00:39:38,400 um to the original uh original 1048 00:39:42,390 --> 00:39:40,400 amount of brightness so that will 1049 00:39:43,589 --> 00:39:42,400 continue if we had more data we'd get to 1050 00:39:46,550 --> 00:39:43,599 see it 1051 00:39:47,990 --> 00:39:46,560 however star uh flares occur at a lot of 1052 00:39:49,990 --> 00:39:48,000 different scales they can be 1053 00:39:51,349 --> 00:39:50,000 anything from a couple of minutes to a 1054 00:39:53,750 --> 00:39:51,359 couple of hours 1055 00:39:55,589 --> 00:39:53,760 in duration so depending on how often 1056 00:39:57,109 --> 00:39:55,599 we're taking measurements of the star 1057 00:39:59,270 --> 00:39:57,119 they could look like this one where we 1058 00:40:01,190 --> 00:39:59,280 get to really see the whole shape 1059 00:40:03,109 --> 00:40:01,200 or they could look more like this one 1060 00:40:05,190 --> 00:40:03,119 which is this large spike that just sort 1061 00:40:06,710 --> 00:40:05,200 of pops out and then disappears 1062 00:40:09,030 --> 00:40:06,720 because this flare is very short 1063 00:40:11,589 --> 00:40:09,040 compared to how often we are measuring 1064 00:40:12,309 --> 00:40:11,599 how bright the star is and so this light 1065 00:40:14,390 --> 00:40:12,319 curve 1066 00:40:15,829 --> 00:40:14,400 is also it it's got a lot of other 1067 00:40:17,829 --> 00:40:15,839 things going on there's some sort of 1068 00:40:19,990 --> 00:40:17,839 periodicity maybe there's some star 1069 00:40:20,630 --> 00:40:20,000 spots which are cooler parts of the star 1070 00:40:22,390 --> 00:40:20,640 that are 1071 00:40:24,790 --> 00:40:22,400 therefore dimmer and so when the star 1072 00:40:27,750 --> 00:40:24,800 rotates these cooler spots 1073 00:40:29,190 --> 00:40:27,760 will rotate with it and sometimes um 1074 00:40:30,150 --> 00:40:29,200 we're seeing them and sometimes we're 1075 00:40:32,790 --> 00:40:30,160 not so so 1076 00:40:33,750 --> 00:40:32,800 they have these small smaller scale 1077 00:40:36,710 --> 00:40:33,760 periodic 1078 00:40:37,829 --> 00:40:36,720 variations as we see the total amount of 1079 00:40:40,470 --> 00:40:37,839 brightness from the star 1080 00:40:42,470 --> 00:40:40,480 change based on the temperature in 1081 00:40:43,349 --> 00:40:42,480 various spots on the face of the star 1082 00:40:46,550 --> 00:40:43,359 we're seeing 1083 00:40:48,950 --> 00:40:46,560 and so that's happening um below these 1084 00:40:50,470 --> 00:40:48,960 this is definitely a flare this little 1085 00:40:52,069 --> 00:40:50,480 one might looks like it's probably a 1086 00:40:53,990 --> 00:40:52,079 flare and this one 1087 00:40:55,589 --> 00:40:54,000 even this one could be it's a little 1088 00:40:57,270 --> 00:40:55,599 hard to tell because this is a slightly 1089 00:41:00,840 --> 00:40:57,280 messier light curve 1090 00:41:00,850 --> 00:41:05,510 [Music] 1091 00:41:09,270 --> 00:41:07,270 so here it's a little harder to hear the 1092 00:41:09,670 --> 00:41:09,280 flares and they're just like little high 1093 00:41:11,589 --> 00:41:09,680 pitched 1094 00:41:12,950 --> 00:41:11,599 pitch blips that come out because 1095 00:41:14,710 --> 00:41:12,960 they're so fast 1096 00:41:16,390 --> 00:41:14,720 but we can see that they do stand out 1097 00:41:20,150 --> 00:41:16,400 above this general 1098 00:41:23,829 --> 00:41:20,160 um activity that's going on in the 1099 00:41:25,430 --> 00:41:23,839 non-flaring star and if we but if we did 1100 00:41:27,670 --> 00:41:25,440 want to really 1101 00:41:28,870 --> 00:41:27,680 dig into what's going on in the star 1102 00:41:30,630 --> 00:41:28,880 without flares well 1103 00:41:32,470 --> 00:41:30,640 we'd pick a part of the light curve 1104 00:41:34,470 --> 00:41:32,480 where there aren't any and then we would 1105 00:41:36,790 --> 00:41:34,480 do what i did with the heartbeat star 1106 00:41:40,710 --> 00:41:36,800 and slow it down and really zero in on 1107 00:41:46,470 --> 00:41:43,829 so that was a brief introduction to 1108 00:41:48,630 --> 00:41:46,480 various different kinds of astronomical 1109 00:41:50,870 --> 00:41:48,640 phenomena that we can sonify 1110 00:41:54,470 --> 00:41:50,880 and now i'm going to hand off to jen who 1111 00:41:59,190 --> 00:41:57,030 hello everyone welcome to the 1112 00:42:02,230 --> 00:41:59,200 astronomify game show 1113

important 1147 00:43:09,190 --> 00:43:07,520 experience for our team 1148 00:43:10,870 --> 00:43:09,200 because it's a great way for us to check 1149 00:43:12,790 --> 00:43:10,880 in with a wide group of people 1150 00:43:13,990 --> 00:43:12,800 and see if these sonifications are 1151 00:43:15,829 --> 00:43:14,000 understandable 1152 00:43:18,150 --> 00:43:15,839 so it'll help us learn how to improve 1153 00:43:20,069 --> 00:43:18,160 our work thank you to everyone who 1154 00:43:23,430 --> 00:43:20,079 participates in advance 1155 00:43:25,589 --> 00:43:23,440 okay let's get started 1156 00:43:26,710 --> 00:43:25,599 so this game is going to have two rounds 1157 00:43:30,870 --> 00:43:26,720 round one is 1158 00:43:32,150 --> 00:43:30,880 flares so remember what clara said 1159 00:43:34,870 --> 00:43:32,160 earlier about flares 1160 00:43:36,230 --> 00:43:34,880 they are explosions on the surface of 1161 00:43:38,870 --> 00:43:36,240 stars 1162 00:43:40,630 --> 00:43:38,880 so first i'm going to show you an 1163 00:43:55,030 --> 00:43:40,640 idealized example 1164 00:43:57,990 --> 00:43:55,040 of what a flare sounds like sonified 1165 00:43:59,910 --> 00:43:58,000 so keep uh you know keep in mind that 1166 00:44:02,790 --> 00:43:59,920 short sudden rise and pitch 1167 00:44:04,390 --> 00:44:02,800 that uh has a slower decay at the end 1168 00:44:05,750 --> 00:44:04,400 that one was very ideal though and now 1169 00:44:06,829 --> 00:44:05,760 we're going to move on to real data 1170 00:44:08,069 --> 00:44:06,839 which might be a little bit more 1171 00:44:10,470 --> 00:44:08,079 difficult 1172 00:44:11,829 --> 00:44:10,480 so in this round i'm going to play four 1173 00:44:14,630 --> 00:44:11,839 sonifications 1174 00:44:16,550 --> 00:44:14,640 after each sonification i will ask you 1175 00:44:19,109 --> 00:44:16,560 did you hear a stellar flare 1176 00:44:20,069 --> 00:44:19,119 so if you're watching live please write 1177 00:44:22,069 --> 00:44:20,079 yes or no 1178 00:44:23,510 --> 00:44:22,079 in the chat and if you're not watching 1179 00:44:25,829 --> 00:44:23,520 live if you're watching later 1180 00:44:27,829 --> 00:44:25,839 can you please uh answer the question in 1181 00:44:30,069 --> 00:44:27,839 the poll as we go along 1182 00:44:30,950 --> 00:44:30,079 uh in the survey i mean link in the 1183 00:44:34,390 --> 00:44:30,960 description 1184 00:44:34,950 --> 00:44:34,400 okay so question one does this contain a 1185 00:44:39,280 --> 00:44:34,960 flare 1186 00:44:39,290 --> 00:44:47,670 [Music] 1187 00:44:51,589 --> 00:44:50,069 okay what do you all think let's uh take 1188 00:44:53,030 --> 00:44:51,599 a few seconds to 1189 00:44:55,030 --> 00:44:53,040 give you a chance to write it in the 1190 00:44:58,309 --> 00:44:55,040 chat answer on the survey 1191 00:45:00,069 --> 00:44:58,319 did you hear a flare what do you think 1192 00:45:03,589 --> 00:45:00,079 okay i think we've given enough time 1193 00:45:08,710 --> 00:45:06,950 yes that was a flare um 1194 00:45:10,710 --> 00:45:08,720 so you can see the arrow on the screen 1195 00:45:19,430 --> 00:45:10,720 and i'll also mention it as we pass it 1196 00:45:24,069 --> 00:45:19,440 uh in this replay 1197 00:45:30,470 --> 00:45:27,670 okay so great job everyone let's move on 1198 00:45:33,349 --> 00:45:30,480 to the next question 1199 00:45:49,670 --> 00:45:33,359 question two does this contain a flare 1200 00:45:53,829 --> 00:45:51,829 okay so let me give you a few seconds to 1201 00:45:56,790 --> 00:45:53,839 write in the chat or respond 1202 00:45:58,230 --> 00:45:56,800 in the survey yes or no did you hear a 1203 00:46:01,510 --> 00:45:58,240 flare there 1204 00:46:05,349 --> 00:46:01,520 there's certainly a lot of variation not 1205 00:46:08,470 --> 00:46:05,359 but was it a flare that's the question 1206 00:46:12,390 --> 00:46:08,480 let's see if anyone's responding yet 1207 00:46:16,470 --> 00:46:12,400 huh okay and let's 1208 00:46:21,990 --> 00:46:19,510 that one did not have a flare 1209 00:46:36,950 --> 00:46:22,000 so let's listen again just to not hear 1210 00:46:41,190 --> 00:46:40,390 okay so question three does this contain 1211 00:46:53,810 --> 00:46:41,200 a flare 1212 00:46:53,820 --> 00:47:00,309 [Music] 1213 00:47:04,870 --> 00:47:02,550 okay so are you listening closely what 1214 00:47:07,910 --> 00:47:04,880 did you hear was there a flare 1215 00:47:09,990 --> 00:47:07,920 what was going on with this one hmm 1216 00:47:11,990 --> 00:47:10,000 i'm wondering if anyone heard anything 1217 00:47:13,190 --> 00:47:12,000 unusual about this one 1218 00:47:15,670 --> 00:47:13,200 maybe they could comment if they think 1219 00:47:15,990 --> 00:47:15,680 it's different anything different about 1220 00:47:20,630 --> 00:47:16,000 this 1221 00:47:25,910 --> 00:47:23,670 okay but let's see 1222 00:47:26,950 --> 00:47:25,920 there was more than one flare not only 1223 00:47:30,790 --> 00:47:26,960 was there one 1224 00:47:32,230 --> 00:47:30,800 there was many flares great job everyone 1225 00:47:34,710 --> 00:47:32,240 for noticing that 1226 00:47:35,750 --> 00:47:34,720 so uh for question four we're going to 1227 00:47:37,670 --> 00:47:35,760 re-listen 1228 00:47:40,069 --> 00:47:37,680 to that previous modification and this 1229 00:47:42,390 --> 00:47:40,079 time i want you to count 1230 00:47:44,309 --> 00:47:42,400 how many flares you hear and this one is 1231 00:47:45,750 --> 00:47:44,319 a little tricky because some of them are 1232 00:47:47,750 --> 00:47:45,760 more subtle than others so you have to 1233 00:47:50,150 --> 00:47:47,760 listen really closely 1234 00:47:51,670 --> 00:47:50,160 okay so how many flares do you hear 1235 00:47:54,870 --> 00:47:51,680 write the number in the chat 1236 00:48:07,980 --> 00:47:54,880 or write the number in on the survey 1237 00:48:07,990 --> 00:48:15,510 [Music] 1238 00:48:20,950 --> 00:48:19,190 okay how many how many flares were there 1239 00:48:22,710 --> 00:48:20,960 so we know there's more than one but how 1240 00:48:25,430 --> 00:48:22,720 many exactly 1241 00:48:27,270 --> 00:48:25,440 let's see oh i see answers starting to 1242 00:48:30,790 --> 00:48:27,280 come in 1243 00:48:34,390 --> 00:48:30,800 okay give you another second to respond 1244 00:48:37,910 --> 00:48:34,400 in the chat 1245 00:48:40,470 --> 00:48:37,920 let's reveal the answer 1246 00:48:41,349 --> 00:48:40,480 there was seven flares and so i've 1247 00:48:43,270 --> 00:48:41,359 marked them off 1248 00:48:45,990 --> 00:48:43,280 so you can visually see them and then as 1249 00:48:51,750 --> 00:48:46,000 they pass along in the replay i'll also 1250 00:48:51,760 --> 00:48:55,990 one two 1251 00:49:05,670 --> 00:49:00,829 three four five 1252 00:49:09,270 --> 00:49:07,829 and so number six i think is the most 1253 00:49:11,430 --> 00:49:09,280 difficult to hear 1254 00:49:13,510 --> 00:49:11,440 uh you and you could see visually it is 1255 00:49:15,510 --> 00:49:13,520 the smallest out of all of them so you 1256 00:49:18,230 --> 00:49:15,520 have to be listening more closely to 1257 00:49:19,589 --> 00:49:18,240 find that one so i'm going to take a 1258 00:49:21,270 --> 00:49:19,599 moment to go back through the chat and 1259 00:49:23,190 --> 00:49:21,280 just see how everyone's doing because 1260 00:49:25,190 --> 00:49:23,200 it's a little bit delayed from what 1261 00:49:26,309 --> 00:49:25,200 i'm seeing i was seeing that everyone 1262 00:49:28,549 --> 00:49:26,319 i'm seeing a lot of 1263 00:49:30,069 --> 00:49:28,559 close answers a lot of seven some sixes 1264 00:49:31,829 --> 00:49:30,079 which i think is understandable on that 1265 00:49:34,870 --> 00:49:31,839 previous question 1266 00:49:38,230 --> 00:49:34,880 okay you all did see that there was 1267 00:49:39,990 --> 00:49:38,240 uh many flares that's awesome 1268 00:49:41,349 --> 00:49:40,000 you're all doing great i think you get a 1269 00:49:43,990 --> 00:49:41,359 million bazillion 1270 00:49:44,790 --> 00:49:44,000 points congratulations we can move on to 1271 00:49:49,430 --> 00:49:44,800 level two 1272 00:49:53,349 --> 00:49:51,349 okay so remember what clara said earlier 1273 00:49:56,630 --> 00:49:53,359 exoplanets are planets 1274 00:49:58,630 --> 00:49:56,640 uh that are in other solar systems and 1275 00:50:00,630 --> 00:49:58,640 they transit when they cross in front of 1276 00:50:02,150 --> 00:50:00,640 their host star and block some of the 1277 00:50:04,150 --> 00:50:02,160 light 1278 00:50:05,589 --> 00:50:04,160 so first i want to show you this 1279 00:50:07,589 --> 00:50:05,599 idealized example 1280 00:50:08,630 --> 00:50:07,599 of what a transit sounds like and we 1281 00:50:10,390 --> 00:50:08,640 heard some earlier 1282 00:50:12,470 --> 00:50:10,400 uh this one's a little bit more drawn 1283 00:50:13,910 --> 00:50:12,480 out so you could hear the detail 1284 00:50:16,630 --> 00:50:13,920 and what a transit sounds like as a 1285 00:50:19,030 --> 00:50:16,640 reminder is it starts at a high pitch 1286 00:50:20,470 --> 00:50:19,040 it deepens as the planet transits in 1287 00:50:25,940 --> 00:50:20,480 front and then it returns to the 1288 00:50:30,710 --> 00:50:25,950 original pitch 1289 00:50:35,270 --> 00:50:33,510 okay so that's what an idealized example 1290 00:50:37,630 --> 00:50:35,280 of a transit sounds like 1291 00:50:39,030 --> 00:50:37,640 so in this round i'm going to play four 1292 00:50:42,069 --> 00:50:39,040 sonifications 1293 00:50:44,230 --> 00:50:42,079 after each sonification i'll ask you how 1294 00:50:46,309 --> 00:50:44,240 many times you heard the exoplanet 1295 00:50:47,829 --> 00:50:46,319 transit so this is a counting one again 1296 00:50:50,069 --> 00:50:47,839 very similar to the final question in 1297 00:50:51,990 --> 00:50:50,079 the flares if you're watching live 1298 00:50:53,430 --> 00:50:52,000 please write the number in the chat so i 1299 00:50:55,030 --> 00:50:53,440 could see how you're doing 1300 00:50:57,270 --> 00:50:55,040 and if you're watching this archive 1301 00:50:58,950 --> 00:50:57,280 later on youtube click the link below 1302 00:51:02,390 --> 00:50:58,960 and start sharing your responses with us 1303 00:51:06,309 --> 00:51:05,510 okay so question one how many transits 1304 00:51:07,990 --> 00:51:06,319 do you count 1305 00:51:25,910 --> 00:51:08,000 write in the chat or respond in the 1306 00:51:29,030 --> 00:51:27,430 what did you all think how many did you 1307 00:51:30,470 --> 00:51:29,040 count 1308 00:51:36,790 --> 00:51:30,480 okay i'll give you a few seconds to 1309 00:51:38,870 --> 00:51:36,800 respond before we reveal the answer 1310 00:51:39,990 --> 00:51:38,880 okay let's see if any chats are coming 1311 00:51:43,190 --> 00:51:40,000 in yet 1312 00:51:44,870 --> 00:51:43,200 huh well i think it's time to move 1313 00:51:47,829 --> 00:51:44,880 forward let's reveal it how many 1314 00:51:50,710 --> 00:51:47,839 transits were there 1315 00:51:52,549 --> 00:51:50,720 five there was five transits and i'll 1316 00:51:57,750 --> 00:51:52,559 make note verbally as we pass through 1317 00:51:57,760 --> 00:52:02,950 one two 1318 00:52:02,960 --> 00:52:08,150 three four 1319 00:52:11,510 --> 00:52:10,710 five and so you can hear that really 1320 00:52:14,950 --> 00:52:11,520 clear dip 1321 00:52:17,990 --> 00:52:14,960 as uh the transit happens okay let's 1322 00:52:20,150 --> 00:52:18,000 move on to the next question 1323 00:52:22,309 --> 00:52:20,160 oh and i see a lot of you are getting 1324 00:52:30,829 --> 00:52:22,319 that one right so that's awesome 1325 00:52:30,839 --> 00:52:46,230 count 1326 00:52:49,430 --> 00:52:48,630 okay what do you think how many transits 1327 00:52:51,430 --> 00:52:49,440 were there 1328 00:52:53,430 --> 00:52:51,440 let me give you a few seconds to write 1329 00:52:58,390 --> 00:52:53,440 that in the chat 1330 00:53:06,950 --> 00:53:03,910 and let's reveal it how many were there 1331 00:53:08,470 --> 00:53:06,960 there was 19 transits so i'm going to 1332 00:53:09,109 --> 00:53:08,480 play it again i'm not going to count as 1333 00:53:11,510 --> 00:53:09,119 each one 1334 00:53:13,990 --> 00:53:11,520 but you'll hear a repeating beat almost 1335 00:53:36,150 --> 00:53:14,000 as at a very regular cadence as the 1336 00:53:39,589 --> 00:53:38,390 okay yeah and i see the answers coming 1337 00:53:42,870 --> 00:53:39,599 in now a lot of you 1338 00:53:44,549 --> 00:53:42,880 heard 19 so fantastic job an extra 1339 00:53:47,430 --> 00:53:44,559 million points to you all 1340 00:54:01,349 --> 00:53:47,440 okay question three how many transits do 1341 00:54:05,030 --> 00:54:03,109 oh i heard a little extra something at 1342 00:54:05,910 --> 00:54:05,040 the end of that one how many transits do 1343 00:54:10,549 --> 00:54:05,920 you count let's 1344 00:54:13,349 --> 00:54:10,559 uh give you a few seconds to respond 1345 00:54:17,190 --> 00:54:13,359 remember in the chat or in the survey 1346 00:54:17,200 --> 00:54:20,710 okay let's find out 1347 00:54:24,870 --> 00:54:23,670 there was three transits and i think 1348 00:54:27,109 --> 00:54:24,880 some of you might have heard that little 1349 00:54:28,710 --> 00:54:27,119 extra flare at the end which you can see 1350 00:54:30,870 --> 00:54:28,720 visually on the right hand side of the 1351 00:54:32,150 --> 00:54:30,880 screen so i'll point out these three 1352 00:54:36,829 --> 00:54:32,160 transits in the flare as 1353 00:54:36,839 --> 00:54:40,069 one 1354 00:54:40,079 --> 00:54:43,270 two 1355 00:54:47,910 --> 00:54:45,430 three and there was a little flare at 1356 00:54:51,030 --> 00:54:47,920 the end the high-pitched flip 1357 00:54:51,750 --> 00:54:51,040 okay seems like a lot of you are saying 1358 00:54:54,950 --> 00:54:51,760 three it's 1359 00:54:55,670 --> 00:54:54,960 awesome okay so this is the final 1360 00:54:57,829 --> 00:54:55,680 question 1361 00:54:59,750 --> 00:54:57,839 and i want to warn you all this final 1362 00:55:01,670 --> 00:54:59,760 light curve is a real challenge 1363 00:55:03,510 --> 00:55:01,680 it is a lot more difficult than the 1364 00:55:05,030 --> 00:55:03,520 others and i even have trouble hearing 1365 00:55:05,750 --> 00:55:05,040 it and i'm working with this data quite 1366 00:55:10,069 --> 00:55:05,760 a lot 1367 00:55:10,079 --> 00:55:16,490 so here we go how many transits do you 1368 00:55:26,549 --> 00:55:18,829 [Music] 1369 00:55:30,630 --> 00:55:28,309 how many transits did you hear what do 1370 00:55:33,589 --> 00:55:30,640 you think 1371 00:55:34,549 --> 00:55:33,599 that's a tough one and so i'm actually 1372 00:55:36,549 --> 00:55:34,559 going to 1373 00:55:38,390 --> 00:55:36,559 try to replay this one once more just to 1374 00:55:50,010 --> 00:55:38,400 give you a second chance to listen 1375 00:55:50,020 --> 00:55:56,870 [Music] 1376 00:56:01,510 --> 00:56:00,390 so okay on that second listen were you 1377 00:56:03,430 --> 00:56:01,520 able to hear it 1378 00:56:05,109 --> 00:56:03,440 it's pretty tough okay so i'm seeing 1379 00:56:10,230 --> 00:56:05,119 some numbers come in 1380 00:56:15,190 --> 00:56:13,430 so there was three transits and i want 1381 00:56:16,150 --> 00:56:15,200 to explain what's going on with this 1382 00:56:17,670 --> 00:56:16,160 star 1383 00:56:19,510 --> 00:56:17,680 you can kind of visually see where they 1384 00:56:19,990 --> 00:56:19,520 are and they're not all at the lowest 1385 00:56:22,870 --> 00:56:20,000 step 1386 00:56:24,950 --> 00:56:22,880 in this slide curve so the baseline 1387 00:56:27,349 --> 00:56:24,960 light coming from the star has its own 1388 00:56:29,510 --> 00:56:27,359 undulating up and down pattern in 1389 00:56:31,190 --> 00:56:29,520 addition to the transit 1390 00:56:32,870 --> 00:56:31,200 it's possibly caused by something like 1391 00:56:36,150 --> 00:56:32,880 star spots which 1392 00:56:38,069 --> 00:56:36,160 are areas with more or less light so 1393 00:56:40,390 --> 00:56:38,079 as the star spins on its axis the 1394 00:56:42,150 --> 00:56:40,400 sonification is representing this up and 1395 00:56:43,750 --> 00:56:42,160 down pattern of the brighter and dimmer 1396 00:56:46,150 --> 00:56:43,760 areas 1397 00:56:47,589 --> 00:56:46,160 as the star's spinning the star spot 1398 00:56:49,829 --> 00:56:47,599 might pass and 1399 00:56:51,589 --> 00:56:49,839 you know deepen or brighten the light 1400 00:56:53,349 --> 00:56:51,599 and so this is happening regularly 1401 00:56:55,190 --> 00:56:53,359 and in addition a planet is also 1402 00:56:57,109 --> 00:56:55,200 transiting in front 1403 00:56:58,950 --> 00:56:57,119 so this sonification is a really great 1404 00:57:01,589 --> 00:56:58,960 example about how studying data 1405 00:57:02,630 --> 00:57:01,599 in multi-modal ways can enhance our 1406 00:57:04,870 --> 00:57:02,640 understanding 1407 00:57:06,549 --> 00:57:04,880 because in some cases audio draws our 1408 00:57:07,349 --> 00:57:06,559 attention to qualities we couldn't see 1409 00:57:09,349 --> 00:57:07,359 in a graph 1410 00:57:10,549 --> 00:57:09,359 but in others it's easier to see it than 1411 00:57:12,630 --> 00:57:10,559 to hear 1412 00:57:14,390 --> 00:57:12,640 so there's a place for sonification and 1413 00:57:15,109 --> 00:57:14,400 a place for visualization but most 1414 00:57:18,230 --> 00:57:15,119 powerfully 1415 00:57:20,549 --> 00:57:18,240 is when we combine the two 1416 00:57:22,309 --> 00:57:20,559 so i'm gonna take a look at the chat and 1417 00:57:23,750 --> 00:57:22,319 see if anyone got that last one let's 1418 00:57:25,109 --> 00:57:23,760 see 1419 00:57:26,950 --> 00:57:25,119 i saw some people got three a lot of 1420 00:57:28,549 --> 00:57:26,960 people thought four 1421 00:57:31,109 --> 00:57:28,559 okay i bet you were hearing the the 1422 00:57:34,549 --> 00:57:31,119 undulation the overall star's brightness 1423 00:57:37,030 --> 00:57:34,559 uh okay awesome so let's move on 1424 00:57:37,990 --> 00:57:37,040 past this um i hope you all enjoyed 1425 00:57:42,069 --> 00:57:38,000 playing 1426 00:57:42,079 --> 00:57:44,910 there's the second one 1427 00:57:44,920 --> 00:57:49,109 [Music] 1428 00:57:54,309 --> 00:57:52,630 okay so for me i'm clearly able to hear 1429 00:57:55,910 --> 00:57:54,319 the second one but it's hard for me to 1430 00:58:02,380 --> 00:57:55,920 hear the first and second so here let's 1431 00:58:02,390 --> 00:58:06,829 [Music] 1432 00:58:11,750 --> 00:58:08,490 again 1433 00:58:13,990 --> 00:58:11,760 [Music] 1434 00:58:15,670 --> 00:58:14,000 okay so there you are that one was a 1435 00:58:17,190 --> 00:58:15,680 pretty tough one 1436 00:58:19,430 --> 00:58:17,200 i really hope you enjoyed playing this 1437 00:58:21,030 --> 00:58:19,440 game and if you like listening to data 1438 00:58:22,870 --> 00:58:21,040 and answering questions like these 1439 00:58:26,270 --> 00:58:22,880 i encourage you to go to our website 1440 00:58:27,829 --> 00:58:26,280 which is astronomify 1441 00:58:30,950 --> 00:58:27,839 a-s-t-r-o-n-i-f-y 1442 00:58:34,230 --> 00:58:30,960 dot read the docs read the docs 1443 00:58:34,630 --> 00:58:34,240 dot io and if you scroll down there's a 1444 00:58:37,270 --> 00:58:34,640 game 1445 00:58:37,670 --> 00:58:37,280 section level one is very similar to 1446 00:58:39,270 --> 00:58:37,680 what 1447 00:58:41,109 --> 00:58:39,280 you just did the exercise you just 1448 00:58:43,349 --> 00:58:41,119 played but level two 1449 00:58:44,150 --> 00:58:43,359 is a totally different one and it 1450 00:58:47,190 --> 00:58:44,160 focuses 1451 00:58:47,990 --> 00:58:47,200 on exoplanets and dives deeper into ways 1452 00:58:51,030 --> 00:58:48,000 you can listen and 1453 00:58:52,710 --> 00:58:51,040 analyze transiting exoplanet data 1454 00:58:54,150 --> 00:58:52,720 and at the end you'll find out what the 1455 00:58:55,589 --> 00:58:54,160 correct and incorrect answers were and 1456 00:58:57,430 --> 00:58:55,599 how you did 1457 00:58:59,910 --> 00:58:57,440 so and once again these survey results 1458 00:59:02,549 --> 00:58:59,920 really uh give us fantastic feedback 1459 00:59:03,990 --> 00:59:02,559 and we can help learn how to improve the 1460 00:59:08,150 --> 00:59:04,000 sonification so thank you 1461 00:59:12,069 --> 00:59:10,630 and finally just want to quickly tell 1462 00:59:13,349 --> 00:59:12,079 you about this 1463 00:59:15,270 --> 00:59:13,359 other part of our project which are 1464 00:59:16,950 --> 00:59:15,280 these interactive exhibits 1465 00:59:18,789 --> 00:59:16,960 main goal of this project has been to 1466 00:59:19,829 --> 00:59:18,799 bring astronomy and sonification to a 1467 00:59:22,150 --> 00:59:19,839 wider audience 1468 00:59:23,670 --> 00:59:22,160 and to that end we're working on three 1469 00:59:25,190 --> 00:59:23,680 interactive sculptures that we could 1470 00:59:26,630 --> 00:59:25,200 show at local events 1471 00:59:29,109 --> 00:59:26,640 and we also want to bring them on the 1472 00:59:30,870 --> 00:59:29,119 road to classrooms and conferences 1473 00:59:32,710 --> 00:59:30,880 and as with the rest of our project we 1474 00:59:35,030 --> 00:59:32,720 want to make sure these exhibits 1475 00:59:36,309 --> 00:59:35,040 are accessible to blind and low vision 1476 00:59:37,990 --> 00:59:36,319 people 1477 00:59:40,150 --> 00:59:38,000 we are so excited to be working with 1478 00:59:42,630 --> 00:59:40,160 bill haas who is a museum 1479 00:59:43,349 --> 00:59:42,640 exhibit designer extraordinaire this guy 1480 00:59:45,670 --> 00:59:43,359 can build 1481 00:59:47,430 --> 00:59:45,680 anything his day job is actually 1482 00:59:50,309 --> 00:59:47,440 designing museum exhibits for the 1483 00:59:51,829 --> 00:59:50,319 smithsonian air and space museum in dc 1484 00:59:55,109 --> 00:59:51,839 so we're so excited to be working with 1485 00:59:59,190 --> 00:59:55,119 him unfortunately covid happened 1486 01:00:01,190 --> 00:59:59,200 what a drag it's pretty awful but 1487 01:00:02,950 --> 01:00:01,200 so we've kind of slowed down the process 1488 01:00:05,270 --> 01:00:02,960 for these in-person exhibits 1489 01:00:06,470 --> 01:00:05,280 because clearly gatherings of people who 1490 01:00:09,430 --> 01:00:06,480 are all touching the same 1491 01:00:10,549 --> 01:00:09,440 sculptures is no longer uh advisable at 1492 01:00:12,309 --> 01:00:10,559 this moment in time 1493 01:00:14,309 --> 01:00:12,319 we're still making some progress and we 1494 01:00:15,270 --> 01:00:14,319 are excited to do more with this in the 1495 01:00:17,510 --> 01:00:15,280 future 1496 01:00:18,390 --> 01:00:17,520 so this image that we're showing on the 1497 01:00:21,109 --> 01:00:18,400 slide 1498 01:00:22,870 --> 01:00:21,119 is an in progress sculpture and it's the 1499 01:00:25,670 --> 01:00:22,880 exhibit i'm most excited about 1500 01:00:26,789 --> 01:00:25,680 it's a light curved xylophone the 1501 01:00:28,789 --> 01:00:26,799 instrument is built 1502 01:00:30,630 --> 01:00:28,799 in the shape of a light curve and as you 1503 01:00:31,270 --> 01:00:30,640 play the instrument you run your hand 1504 01:00:33,430 --> 01:00:31,280 along 1505 01:00:35,109 --> 01:00:33,440 the shape which is a great way to 1506 01:00:37,430 --> 01:00:35,119 physically understand 1507 01:00:40,230 --> 01:00:37,440 uh the shape of a light curve and then 1508 01:00:42,470 --> 01:00:40,240 as you're making the noise it's actually 1509 01:00:43,349 --> 01:00:42,480 creating music in the sound that we 1510 01:00:46,309 --> 01:00:43,359 would sonify 1511 01:00:47,990 --> 01:00:46,319 so a higher pitch for more light lower 1512 01:00:49,910 --> 01:00:48,000 pitch for less light 1513 01:00:51,349 --> 01:00:49,920 so it's in progress and the sounds still 1514 01:00:53,190 --> 01:00:51,359 need a little bit of tweaking 1515 01:00:54,549 --> 01:00:53,200 but i can't tell you how excited i am 1516 01:00:56,870 --> 01:00:54,559 about the sculpture 1517 01:01:09,109 --> 01:00:56,880 and i have a short video to show you to 1518 01:01:14,950 --> 01:01:13,030 okay so that's um 1519 01:01:16,230 --> 01:01:14,960 that's that portion of the project if 1520 01:01:17,829 --> 01:01:16,240 you're excited about the things you've 1521 01:01:19,990 --> 01:01:17,839 been hearing in this presentation 1522 01:01:20,950 --> 01:01:20,000 i want to invite you to join us 1523 01:01:23,589 --> 01:01:20,960 astronomify 1524 01:01:25,750 --> 01:01:23,599 is a python package that we built to 1525 01:01:27,109 --> 01:01:25,760 sonify our data and by we i mean clara 1526 01:01:30,309 --> 01:01:27,119 clara has built it 1527 01:01:33,270 --> 01:01:30,319 um mostly by herself very impressive 1528 01:01:34,470 --> 01:01:33,280 uh so it is open source and you could 1529 01:01:35,990 --> 01:01:34,480 find it on github 1530 01:01:37,670 --> 01:01:36,000 and if you're familiar with python 1531 01:01:39,829 --> 01:01:37,680 coding i encourage you to try 1532 01:01:40,789 --> 01:01:39,839 installing it and to sonify your own 1533 01:01:42,789 --> 01:01:40,799 data 1534 01:01:44,549 --> 01:01:42,799 we also welcome contributions if that's 1535 01:01:45,990 --> 01:01:44,559 something you're into 1536 01:01:47,750 --> 01:01:46,000 and also if you're just generally 1537 01:01:49,510 --> 01:01:47,760 interested in this project excited about 1538 01:01:51,589 --> 01:01:49,520 sonification and space 1539 01:01:53,109 --> 01:01:51,599 whether you code or not i encourage you 1540 01:01:54,710 --> 01:01:53,119 to check out our website 1541 01:01:56,870 --> 01:01:54,720 and join our mailing list so you can 1542 01:01:58,230 --> 01:01:56,880 listen to more sonifications hear about 1543 01:02:00,789 --> 01:01:58,240 project updates 1544 01:02:01,270 --> 01:02:00,799 and feature events like this one once 1545 01:02:04,950 --> 01:02:01,280 again 1546 01:02:09,349 --> 01:02:04,960 uh the website is astronofy 1547 01:02:12,549 --> 01:02:09,359 r o a-s-t-r-o-n i f y dot read the docs 1548 01:02:14,069 --> 01:02:12,559 dot io thank you all so much for tuning 1549 01:02:15,910 --> 01:02:14,079 in to this presentation 1550 01:02:17,190 --> 01:02:15,920 we are very excited to answer whatever 1551 01:02:20,150 --> 01:02:17,200 questions you may have 1552 01:02:21,670 --> 01:02:20,160 so thank you all right thank you very 1553 01:02:23,990 --> 01:02:21,680 much jen that was 1554 01:02:25,029 --> 01:02:24,000 really really a lot of fun i was 1555 01:02:27,029 --> 01:02:25,039 watching the chat 1556 01:02:28,789 --> 01:02:27,039 and everybody seemed to have a blast 1557 01:02:31,270 --> 01:02:28,799 playing this little game show 1558 01:02:32,630 --> 01:02:31,280 uh to go along with it so this is one of 1559 01:02:35,430 --> 01:02:32,640 the first times we've done this at the 1560 01:02:37,430 --> 01:02:35,440 public lecture series not only 1561 01:02:39,670 --> 01:02:37,440 given them information but actually let 1562 01:02:41,349 --> 01:02:39,680 them utilize that information so thank 1563 01:02:44,069 --> 01:02:41,359 you all for a 1564 01:02:45,750 --> 01:02:44,079 wonderful presentation and one of the 1565 01:02:46,950 --> 01:02:45,760 questions that somebody asked on there 1566 01:02:50,069 --> 01:02:46,960 was well the same question 1567 01:02:52,069 --> 01:02:50,079 i had was um just can we get an 1568 01:02:53,430 --> 01:02:52,079 idea of what inspired you to do this 1569 01:02:56,390 --> 01:02:53,440 sonification were there other 1570 01:02:57,670 --> 01:02:56,400 projects that you saw that um that that 1571 01:02:59,589 --> 01:02:57,680 pulled you into this 1572 01:03:01,109 --> 01:02:59,599 um you know i'd like to hear from each 1573 01:03:02,710 --> 01:03:01,119 one each one of you as to you know 1574 01:03:04,789 --> 01:03:02,720 what what what brought you into this 1575 01:03:07,990 --> 01:03:04,799 what what what what pulled you into 1576 01:03:11,109 --> 01:03:10,150 yeah i like to have maybe uh jen and 1577 01:03:13,270 --> 01:03:11,119 then clara 1578 01:03:14,390 --> 01:03:13,280 uh and then i'll i'll if i have time 1579 01:03:16,390 --> 01:03:14,400 i'll go through the 1580 01:03:17,750 --> 01:03:16,400 the inspiration for me so maybe jen do 1581 01:03:19,589 --> 01:03:17,760 you want to say something about 1582 01:03:21,910 --> 01:03:19,599 what inspires you to work on the project 1583 01:03:23,029 --> 01:03:21,920 yeah i mean so i have i come from an art 1584 01:03:25,109 --> 01:03:23,039 background i have a bit of an 1585 01:03:27,349 --> 01:03:25,119 untraditional background for working 1586 01:03:29,109 --> 01:03:27,359 at a space telescope science institute 1587 01:03:32,710 --> 01:03:29,119 where it's mostly people 1588 01:03:34,870 --> 01:03:32,720 who are developers and scientists and so 1589 01:03:37,029 --> 01:03:34,880 um i'm really excited about the idea of 1590 01:03:38,150 --> 01:03:37,039 trying to create art with data 1591 01:03:40,390 --> 01:03:38,160 and you know different ways of 1592 01:03:41,510 --> 01:03:40,400 visualizing data and it's been something 1593 01:03:43,750 --> 01:03:41,520 i've been thinking about 1594 01:03:45,829 --> 01:03:43,760 and we had this great public lecture by 1595 01:03:48,870 --> 01:03:45,839 this fellow named gary forran 1596 01:03:50,150 --> 01:03:48,880 who is a phd candidate and uh swinborn i 1597 01:03:52,309 --> 01:03:50,160 believe in australia 1598 01:03:53,750 --> 01:03:52,319 and he came in to talk to us about the 1599 01:03:55,750 --> 01:03:53,760 project he's working on 1600 01:03:57,510 --> 01:03:55,760 because he's actually blind and he's 1601 01:04:00,710 --> 01:03:57,520 working on his physics degree 1602 01:04:02,789 --> 01:04:00,720 and so he's working on studying data but 1603 01:04:05,190 --> 01:04:02,799 i think he was struggling he was 1604 01:04:07,109 --> 01:04:05,200 probably needing people to 1605 01:04:08,549 --> 01:04:07,119 verbally describe what they were seeing 1606 01:04:11,029 --> 01:04:08,559 on charts and graphs 1607 01:04:12,069 --> 01:04:11,039 and so he and a few other people are 1608 01:04:15,589 --> 01:04:12,079 working together 1609 01:04:18,549 --> 01:04:15,599 on sonification and he gave a talk about 1610 01:04:20,230 --> 01:04:18,559 all the promise that he that it has and 1611 01:04:22,230 --> 01:04:20,240 he played some sonifications 1612 01:04:24,069 --> 01:04:22,240 and i was just really excited and 1613 01:04:25,430 --> 01:04:24,079 inspired to hear this and 1614 01:04:28,309 --> 01:04:25,440 i mean both from the accessibility 1615 01:04:30,470 --> 01:04:28,319 standard of course but also 1616 01:04:31,990 --> 01:04:30,480 just imagining the the art and the 1617 01:04:33,990 --> 01:04:32,000 interactivity and it's such an amazing 1618 01:04:38,390 --> 01:04:34,000 way of putting you inside data 1619 01:04:42,230 --> 01:04:40,870 all right clara you have a any any 1620 01:04:45,670 --> 01:04:42,240 anything to add 1621 01:04:47,589 --> 01:04:45,680 yeah so i i mean i do have a physics 1622 01:04:49,190 --> 01:04:47,599 background and i work at space telescope 1623 01:04:50,150 --> 01:04:49,200 but i also have a music composition 1624 01:04:53,510 --> 01:04:50,160 background 1625 01:04:56,150 --> 01:04:53,520 and so um day to day sonification 1626 01:04:57,670 --> 01:04:56,160 when you know i learned about it as a 1627 01:04:58,870 --> 01:04:57,680 thing it was something that i was very 1628 01:05:01,589 --> 01:04:58,880 interested in and 1629 01:05:02,950 --> 01:05:01,599 i've done some sort of electronic music 1630 01:05:06,549 --> 01:05:02,960 in the past and so 1631 01:05:08,390 --> 01:05:06,559 is very um you know i i used to use 1632 01:05:09,589 --> 01:05:08,400 random numbers and things as as 1633 01:05:11,270 --> 01:05:09,599 inspiration so 1634 01:05:12,789 --> 01:05:11,280 so it was like oh yes this is something 1635 01:05:14,309 --> 01:05:12,799 that would be cool to play around with 1636 01:05:15,990 --> 01:05:14,319 and i actually missed gary's talk 1637 01:05:16,710 --> 01:05:16,000 because i think i was out of town at the 1638 01:05:18,230 --> 01:05:16,720 time 1639 01:05:20,870 --> 01:05:18,240 and so jen was like well this was 1640 01:05:23,349 --> 01:05:20,880 amazing and we should meet this person 1641 01:05:25,190 --> 01:05:23,359 and then scott had who's gonna talk last 1642 01:05:26,630 --> 01:05:25,200 but scott had the idea for this project 1643 01:05:28,230 --> 01:05:26,640 and was like you seem like you might be 1644 01:05:30,069 --> 01:05:28,240 interested and i was like yes i 1645 01:05:32,309 --> 01:05:30,079 definitely want to do this 1646 01:05:34,870 --> 01:05:32,319 um and i also since jen brought up that 1647 01:05:36,470 --> 01:05:34,880 gary is working on sonification 1648 01:05:38,549 --> 01:05:36,480 one of the goals of this project that 1649 01:05:41,990 --> 01:05:38,559 hasn't been coded yet because 1650 01:05:45,349 --> 01:05:42,000 these things take time is that is to 1651 01:05:45,750 --> 01:05:45,359 have the the software that he's working 1652 01:05:47,510 --> 01:05:45,760 on 1653 01:05:49,430 --> 01:05:47,520 isn't isn't something that can be really 1654 01:05:51,910 --> 01:05:49,440 run through the web 1655 01:05:53,670 --> 01:05:51,920 and you have to bring the data to it and 1656 01:05:55,349 --> 01:05:53,680 it has to come into it in specific 1657 01:05:56,630 --> 01:05:55,359 format so one of the things we want to 1658 01:05:58,630 --> 01:05:56,640 add to our 1659 01:06:00,309 --> 01:05:58,640 software is the ability to write out the 1660 01:06:03,910 --> 01:06:00,319 configuration files 1661 01:06:04,710 --> 01:06:03,920 for his star sound so that it can be a 1662 01:06:07,750 --> 01:06:04,720 through line 1663 01:06:10,390 --> 01:06:07,760 to easily get data from 1664 01:06:12,309 --> 01:06:10,400 mass and then sauna and then sonify it 1665 01:06:14,230 --> 01:06:12,319 and we are providing you know 1666 01:06:15,349 --> 01:06:14,240 python sonification because that is a 1667 01:06:17,430 --> 01:06:15,359 very popular 1668 01:06:19,349 --> 01:06:17,440 language in astronomy but we also like 1669 01:06:20,710 --> 01:06:19,359 one of our goals as part of our 1670 01:06:22,470 --> 01:06:20,720 accessibility goal is to be 1671 01:06:23,670 --> 01:06:22,480 interoperable with the other projects 1672 01:06:25,270 --> 01:06:23,680 that are out there 1673 01:06:26,789 --> 01:06:25,280 um because there are a lot of different 1674 01:06:29,109 --> 01:06:26,799 ways to sonify with a lot of different 1675 01:06:31,990 --> 01:06:29,119 strengths and weaknesses depending on 1676 01:06:32,630 --> 01:06:32,000 what specific task you're looking for 1677 01:06:34,789 --> 01:06:32,640 all right 1678 01:06:35,910 --> 01:06:34,799 fantastic scott how about you finish us 1679 01:06:37,029 --> 01:06:35,920 up on this question 1680 01:06:38,870 --> 01:06:37,039 i'll try and do the short version 1681 01:06:39,990 --> 01:06:38,880 there's a lot of other questions but um 1682 01:06:41,589 --> 01:06:40,000 yeah i was 1683 01:06:43,109 --> 01:06:41,599 we go to an annual meeting every year 1684 01:06:46,069 --> 01:06:43,119 and i like to go up and down all the 1685 01:06:48,549 --> 01:06:46,079 posters and i stumbled across 1686 01:06:50,069 --> 01:06:48,559 kate's poster uh kate meredith who's in 1687 01:06:50,950 --> 01:06:50,079 the chat as well as bill our other two 1688 01:06:53,589 --> 01:06:50,960 teammates 1689 01:06:54,789 --> 01:06:53,599 um so great work on them and and i ran 1690 01:06:57,670 --> 01:06:54,799 across the student who 1691 01:06:59,190 --> 01:06:57,680 was giving this demo of showing how 1692 01:07:02,470 --> 01:06:59,200 constellations could be 1693 01:07:03,990 --> 01:07:02,480 shown on an umbrella with things stuck 1694 01:07:05,990 --> 01:07:04,000 on the umbrellas that you could touch 1695 01:07:07,829 --> 01:07:06,000 and feel the constellations for those 1696 01:07:09,589 --> 01:07:07,839 who were blind and you could spin the 1697 01:07:10,150 --> 01:07:09,599 umbrella which looks like a dome and 1698 01:07:12,789 --> 01:07:10,160 really 1699 01:07:14,230 --> 01:07:12,799 get a sense of how the sky moves from 1700 01:07:15,430 --> 01:07:14,240 touch and that was just a fantastic 1701 01:07:17,990 --> 01:07:15,440 conversation 1702 01:07:19,029 --> 01:07:18,000 so that combined that that was sort of 1703 01:07:20,390 --> 01:07:19,039 started our relation a working 1704 01:07:21,270 --> 01:07:20,400 relationship with kate and glass 1705 01:07:23,589 --> 01:07:21,280 education 1706 01:07:25,029 --> 01:07:23,599 and then that combined with um my dad 1707 01:07:26,870 --> 01:07:25,039 did some volunteer work for the lions 1708 01:07:28,309 --> 01:07:26,880 club which is a volunteer organization 1709 01:07:30,470 --> 01:07:28,319 here in the united states 1710 01:07:32,150 --> 01:07:30,480 that has done a lot of work for um for 1711 01:07:32,950 --> 01:07:32,160 people who are blind and low vision and 1712 01:07:35,990 --> 01:07:32,960 i guess i 1713 01:07:37,109 --> 01:07:36,000 took on that sort of interest as well um 1714 01:07:38,390 --> 01:07:37,119 but yeah i want to make it clear to 1715 01:07:39,750 --> 01:07:38,400 everybody we are not the people who have 1716 01:07:41,190 --> 01:07:39,760 invented sonification 1717 01:07:42,870 --> 01:07:41,200 people been working on solidification 1718 01:07:44,789 --> 01:07:42,880 for decades um 1719 01:07:46,309 --> 01:07:44,799 but you know we're we're taking a lot of 1720 01:07:47,270 --> 01:07:46,319 that work and and trying to make it part 1721 01:07:50,470 --> 01:07:47,280 of the archive 1722 01:07:52,470 --> 01:07:50,480 so yeah all right fantastic all right so 1723 01:07:54,549 --> 01:07:52,480 grant justice has been monitoring the 1724 01:07:57,109 --> 01:07:54,559 chat more closely than any of us 1725 01:07:58,710 --> 01:07:57,119 and grant why don't you come join us and 1726 01:08:01,109 --> 01:07:58,720 tell us the questions you found in the 1727 01:08:03,270 --> 01:08:01,119 chat for the group 1728 01:08:06,150 --> 01:08:03,280 absolutely first off i would just like 1729 01:08:08,829 --> 01:08:06,160 to say thank you to the audience because 1730 01:08:10,470 --> 01:08:08,839 we had some great answers and some great 1731 01:08:15,589 --> 01:08:10,480 interaction um 1732 01:08:18,950 --> 01:08:17,110 so on one of the first graphs that you 1733 01:08:19,749 --> 01:08:18,960 see that you put up i believe it was the 1734 01:08:22,470 --> 01:08:19,759 very first 1735 01:08:25,510 --> 01:08:22,480 sonification graph what is the 1736 01:08:27,349 --> 01:08:25,520 explanation for the decreasing slope 1737 01:08:30,229 --> 01:08:27,359 of the relative lower values of 1738 01:08:32,789 --> 01:08:30,239 oscillating star brightness 1739 01:08:33,749 --> 01:08:32,799 yeah i'll take a stab at that one first 1740 01:08:35,910 --> 01:08:33,759 um 1741 01:08:38,229 --> 01:08:35,920 so i think the the the person there 1742 01:08:40,709 --> 01:08:38,239 noted that in addition to the pattern 1743 01:08:42,550 --> 01:08:40,719 there was a sort of trend as well and 1744 01:08:43,110 --> 01:08:42,560 and i don't have a direct answer for 1745 01:08:45,590 --> 01:08:43,120 that but 1746 01:08:47,349 --> 01:08:45,600 uh it one thing to point out was it was 1747 01:08:48,950 --> 01:08:47,359 zoomed in and so if we zoomed out the 1748 01:08:51,910 --> 01:08:48,960 full light curve which 1749 01:08:53,430 --> 01:08:51,920 uh if it's kepler or tess they they 1750 01:08:57,269 --> 01:08:53,440 observe the targets 1751 01:09:00,070 --> 01:08:57,279 every half an hour for months at a time 1752 01:09:01,669 --> 01:09:00,080 continuously and so you could actually 1753 01:09:04,309 --> 01:09:01,679 see a better pattern now whether that 1754 01:09:05,749 --> 01:09:04,319 undulating pattern is something real 1755 01:09:05,990 --> 01:09:05,759 going on with the star itself which it 1756 01:09:08,789 --> 01:09:06,000 might 1757 01:09:09,910 --> 01:09:08,799 be or sort of some calibration that 1758 01:09:12,950 --> 01:09:09,920 wasn't perfectly done 1759 01:09:14,070 --> 01:09:12,960 we'd have to investigate um but i i do 1760 01:09:15,990 --> 01:09:14,080 think there is an unjuly 1761 01:09:17,590 --> 01:09:16,000 undulating pattern that you saw even in 1762 01:09:19,269 --> 01:09:17,600 the zoomed in version 1763 01:09:20,789 --> 01:09:19,279 whether that's sort of not perfect 1764 01:09:22,229 --> 01:09:20,799 calibration or something real we'd have 1765 01:09:23,990 --> 01:09:22,239 to do some real science behind it but 1766 01:09:25,590 --> 01:09:24,000 that was a good observation and many 1767 01:09:26,550 --> 01:09:25,600 times those patterns are real 1768 01:09:29,590 --> 01:09:26,560 and they tell us something about the 1769 01:09:31,269 --> 01:09:29,600 physics happening right and 1770 01:09:34,709 --> 01:09:31,279 can i just interject are we talking 1771 01:09:37,829 --> 01:09:34,719 about the first light curve on the um 1772 01:09:41,110 --> 01:09:37,839 game show no it was the 1773 01:09:43,269 --> 01:09:41,120 part of the first talk the very first 1774 01:09:46,390 --> 01:09:43,279 one you guys put up 1775 01:09:48,709 --> 01:09:46,400 when we were still explaining 1776 01:09:50,309 --> 01:09:48,719 but scott answered the majority of okay 1777 01:09:53,269 --> 01:09:50,319 because i would say i know at least 1778 01:09:54,229 --> 01:09:53,279 like the kepler 12b one and one and the 1779 01:09:59,350 --> 01:09:54,239 the 1780 01:10:00,709 --> 01:09:59,360 it is it is instrumental because i've 1781 01:10:02,149 --> 01:10:00,719 worked with i've worked with those 1782 01:10:04,870 --> 01:10:02,159 specific light curves 1783 01:10:06,870 --> 01:10:04,880 and there is an artificial trend that 1784 01:10:09,669 --> 01:10:06,880 the kepler data has 1785 01:10:10,950 --> 01:10:09,679 that typically um and i left it in 1786 01:10:11,910 --> 01:10:10,960 intentionally because that's something 1787 01:10:13,750 --> 01:10:11,920 that you have to deal with as an 1788 01:10:16,870 --> 01:10:13,760 astronomer determining whether or not 1789 01:10:21,110 --> 01:10:16,880 it's real and in this case it's it's 1790 01:10:23,669 --> 01:10:21,120 an artifact of of the instrument 1791 01:10:25,270 --> 01:10:23,679 cool that's actually leading me to the 1792 01:10:27,189 --> 01:10:25,280 second one which was 1793 01:10:29,510 --> 01:10:27,199 does the longer scale variation show 1794 01:10:32,790 --> 01:10:29,520 this as well which is what scott just 1795 01:10:36,229 --> 01:10:32,800 elaborated on before we got there so 1796 01:10:38,950 --> 01:10:36,239 um next up who slash 1797 01:10:40,870 --> 01:10:38,960 when did astro sonification come about 1798 01:10:41,750 --> 01:10:40,880 because we use sonification in a lot of 1799 01:10:44,870 --> 01:10:41,760 different methods 1800 01:10:47,830 --> 01:10:44,880 but asternification 1801 01:10:48,790 --> 01:10:47,840 that is a good question uh actually 1802 01:10:50,550 --> 01:10:48,800 probably kate 1803 01:10:52,149 --> 01:10:50,560 if if kate's still in the chat would 1804 01:10:52,950 --> 01:10:52,159 know the best but i want to say it's 1805 01:10:55,510 --> 01:10:52,960 been around 1806 01:10:57,189 --> 01:10:55,520 since at least the mid 90s i think 1807 01:10:58,950 --> 01:10:57,199 there's a pretty seminal paper 1808 01:11:00,310 --> 01:10:58,960 not necessarily about astronomy but 1809 01:11:02,550 --> 01:11:00,320 other types of data 1810 01:11:03,990 --> 01:11:02,560 from i think like 1997 or something like 1811 01:11:06,950 --> 01:11:04,000 that if i'm not mistaken 1812 01:11:07,510 --> 01:11:06,960 um and i i know for a fact over the last 1813 01:11:10,229 --> 01:11:07,520 10 1814 01:11:11,350 --> 01:11:10,239 or or or even more years there have been 1815 01:11:14,550 --> 01:11:11,360 individuals 1816 01:11:16,550 --> 01:11:14,560 working very hard in ways of 1817 01:11:18,630 --> 01:11:16,560 representing not just light curves like 1818 01:11:20,229 --> 01:11:18,640 we've shown but also people are doing 1819 01:11:21,830 --> 01:11:20,239 work to sonify images 1820 01:11:24,070 --> 01:11:21,840 if you can believe it or not and they 1821 01:11:26,630 --> 01:11:24,080 have some really good solutions for that 1822 01:11:28,709 --> 01:11:26,640 as well as other types of data um so 1823 01:11:30,470 --> 01:11:28,719 it's it's a it's a small but growing 1824 01:11:31,430 --> 01:11:30,480 field and one of the things we're trying 1825 01:11:33,350 --> 01:11:31,440 to do 1826 01:11:35,350 --> 01:11:33,360 um with other groups around the world 1827 01:11:36,870 --> 01:11:35,360 interested in sonification of which i 1828 01:11:37,430 --> 01:11:36,880 saw at least a couple in the chat as 1829 01:11:39,669 --> 01:11:37,440 well 1830 01:11:41,430 --> 01:11:39,679 is to work together to try and pull our 1831 01:11:44,870 --> 01:11:41,440 resources together 1832 01:11:45,910 --> 01:11:44,880 yeah scott says um like when you showed 1833 01:11:48,470 --> 01:11:45,920 that you know you can 1834 01:11:49,990 --> 01:11:48,480 feel the the motion of the sine wave 1835 01:11:52,550 --> 01:11:50,000 with the sound and everything 1836 01:11:54,229 --> 01:11:52,560 um people have uh created several 1837 01:11:56,229 --> 01:11:54,239 sonifications in astronomy 1838 01:11:57,430 --> 01:11:56,239 where you take your mouse and move it 1839 01:11:59,590 --> 01:11:57,440 across the image 1840 01:12:01,430 --> 01:11:59,600 and the sound changes as you go across 1841 01:12:02,229 --> 01:12:01,440 different things to indicate certain 1842 01:12:05,510 --> 01:12:02,239 things like 1843 01:12:06,070 --> 01:12:05,520 the hubble ultra deep field each galaxy 1844 01:12:08,229 --> 01:12:06,080 that you 1845 01:12:10,390 --> 01:12:08,239 come across has a different tone based 1846 01:12:13,189 --> 01:12:10,400 upon the redshift of that galaxy 1847 01:12:13,910 --> 01:12:13,199 for example so you know doing images as 1848 01:12:16,870 --> 01:12:13,920 well as 1849 01:12:17,590 --> 01:12:16,880 light curves uh you know quite a quite a 1850 01:12:20,390 --> 01:12:17,600 variety 1851 01:12:23,030 --> 01:12:20,400 possibilities so you mentioned them 1852 01:12:25,270 --> 01:12:23,040 moving the mouse across the screen 1853 01:12:27,590 --> 01:12:25,280 i know of some blind astronomers who use 1854 01:12:29,189 --> 01:12:27,600 touch pads and some ways of physically 1855 01:12:31,430 --> 01:12:29,199 interacting with 1856 01:12:33,189 --> 01:12:31,440 a piece of hardware that they could 1857 01:12:35,270 --> 01:12:33,199 actually feel 1858 01:12:37,189 --> 01:12:35,280 where they're moving and then the sound 1859 01:12:38,709 --> 01:12:37,199 gives feedback as they run their hand 1860 01:12:41,430 --> 01:12:38,719 over a certain area 1861 01:12:42,149 --> 01:12:41,440 um and then also uh similarly using kind 1862 01:12:44,790 --> 01:12:42,159 of dj 1863 01:12:45,910 --> 01:12:44,800 kits and interacting with the 1864 01:12:48,550 --> 01:12:45,920 sonifications 1865 01:12:50,709 --> 01:12:48,560 and updating them uh with this like 1866 01:12:53,830 --> 01:12:50,719 physical interface 1867 01:12:55,110 --> 01:12:53,840 cool that's so cool what's up grant 1868 01:12:57,669 --> 01:12:55,120 what's next 1869 01:12:58,950 --> 01:12:57,679 all right so next one is kind of a 1870 01:13:01,750 --> 01:12:58,960 continuation as well 1871 01:13:04,149 --> 01:13:01,760 what else do we use sonification for i 1872 01:13:06,470 --> 01:13:04,159 think more specifically in science but 1873 01:13:07,590 --> 01:13:06,480 just as a general like an idea of the 1874 01:13:11,270 --> 01:13:07,600 usage for 1875 01:13:14,070 --> 01:13:11,280 the audience i know so many things 1876 01:13:15,590 --> 01:13:14,080 sorry go ahead i was going to say from 1877 01:13:18,229 --> 01:13:15,600 my experience i know that it's 1878 01:13:19,830 --> 01:13:18,239 used in testing for like pressure cracks 1879 01:13:23,830 --> 01:13:19,840 in nuclear reactors 1880 01:13:25,270 --> 01:13:23,840 and um quite a bit of manufacturing as 1881 01:13:28,630 --> 01:13:25,280 well 1882 01:13:31,350 --> 01:13:28,640 yeah i so i actually went and did 1883 01:13:31,830 --> 01:13:31,360 i don't know not like a survey but i did 1884 01:13:33,990 --> 01:13:31,840 uh 1885 01:13:35,590 --> 01:13:34,000 just googling around to see what else is 1886 01:13:36,870 --> 01:13:35,600 out there and there's a lot of different 1887 01:13:38,550 --> 01:13:36,880 things there was 1888 01:13:40,310 --> 01:13:38,560 something that was i guess this isn't 1889 01:13:40,709 --> 01:13:40,320 directly in science but it was really 1890 01:13:44,830 --> 01:13:40,719 cool 1891 01:13:47,830 --> 01:13:44,840 it was getting it was sonifying 1892 01:13:51,110 --> 01:13:47,840 um the 1893 01:13:54,149 --> 01:13:51,120 to look at the population 1894 01:13:57,189 --> 01:13:54,159 density based on subway stop 1895 01:14:00,229 --> 01:13:57,199 in manhattan and so 1896 01:14:01,750 --> 01:14:00,239 you would so the way it it matched 1897 01:14:03,030 --> 01:14:01,760 through is that it was like you took a 1898 01:14:05,590 --> 01:14:03,040 train line and it would 1899 01:14:06,870 --> 01:14:05,600 so so there was a way easy way right 1900 01:14:08,950 --> 01:14:06,880 because 1901 01:14:10,790 --> 01:14:08,960 people are familiar with what the subway 1902 01:14:12,390 --> 01:14:10,800 system looks like in manhattan and 1903 01:14:14,070 --> 01:14:12,400 and then and so that would take you 1904 01:14:17,030 --> 01:14:14,080 through and it would change 1905 01:14:18,709 --> 01:14:17,040 it would change with what i remember was 1906 01:14:20,229 --> 01:14:18,719 population density but i think you could 1907 01:14:22,229 --> 01:14:20,239 also change it and have 1908 01:14:23,750 --> 01:14:22,239 like average numbers of different things 1909 01:14:27,030 --> 01:14:23,760 which was very cool 1910 01:14:33,990 --> 01:14:30,470 some um sonifications with 1911 01:14:37,030 --> 01:14:34,000 earthquakes um detection as well 1912 01:14:38,950 --> 01:14:37,040 um it comes up in a lot of places i 1913 01:14:41,510 --> 01:14:38,960 think it's worth mentioning too that 1914 01:14:42,229 --> 01:14:41,520 there are sonifications in just everyday 1915 01:14:43,750 --> 01:14:42,239 objects 1916 01:14:45,669 --> 01:14:43,760 that you use and you just probably 1917 01:14:47,750 --> 01:14:45,679 haven't thought of it as sonification 1918 01:14:49,669 --> 01:14:47,760 so i mean the heartbeat star we showed 1919 01:14:51,830 --> 01:14:49,679 is based on an ekg machine 1920 01:14:53,669 --> 01:14:51,840 but an ekg machine is a perfect example 1921 01:14:54,470 --> 01:14:53,679 of sonification being used in the 1922 01:14:56,470 --> 01:14:54,480 medical field 1923 01:14:57,990 --> 01:14:56,480 that you've definitely well you've 1924 01:14:59,430 --> 01:14:58,000 probably heard before so 1925 01:15:00,950 --> 01:14:59,440 lots of examples like that once you 1926 01:15:01,270 --> 01:15:00,960 start looking for it you'll you'll see 1927 01:15:03,669 --> 01:15:01,280 it 1928 01:15:05,669 --> 01:15:03,679 i mean even your microwave counting down 1929 01:15:08,830 --> 01:15:05,679 the number of seconds and ringing 1930 01:15:10,790 --> 01:15:08,840 is i some sort of form of sonification i 1931 01:15:14,550 --> 01:15:10,800 think 1932 01:15:17,270 --> 01:15:14,560 pot bubbling right 1933 01:15:18,870 --> 01:15:17,280 um yeah you're not paying attention but 1934 01:15:20,229 --> 01:15:18,880 you're hearing the pot bubbling on the 1935 01:15:22,709 --> 01:15:20,239 stove and you go ah 1936 01:15:25,030 --> 01:15:22,719 time to go you know take care of the the 1937 01:15:27,430 --> 01:15:25,040 pasta or whatever or when the teapot 1938 01:15:28,229 --> 01:15:27,440 uh whales yes exactly that's that's a 1939 01:15:30,070 --> 01:15:28,239 great one 1940 01:15:31,350 --> 01:15:30,080 or just pouring a glass of water you 1941 01:15:33,990 --> 01:15:31,360 hear it the sound 1942 01:15:35,669 --> 01:15:34,000 get higher pitched as you near the top 1943 01:15:37,189 --> 01:15:35,679 that's one a blind friend of mine 1944 01:15:39,110 --> 01:15:37,199 pointed out to me that i never thought 1945 01:15:39,990 --> 01:15:39,120 about but you can absolutely do a lot of 1946 01:15:41,830 --> 01:15:40,000 things and 1947 01:15:44,229 --> 01:15:41,840 the visualization makes it much more 1948 01:15:46,390 --> 01:15:44,239 accessible as well which is awesome 1949 01:15:48,630 --> 01:15:46,400 or the sonification rather well and this 1950 01:15:50,470 --> 01:15:48,640 is also the distinction that scott was 1951 01:15:53,669 --> 01:15:50,480 talking about at the very beginning 1952 01:15:57,270 --> 01:15:53,679 um the the tea kettle wailing 1953 01:15:58,870 --> 01:15:57,280 is could be is a sonification that water 1954 01:16:00,950 --> 01:15:58,880 is boiling and that's making a sound 1955 01:16:03,350 --> 01:16:00,960 happen but hearing the water boiling 1956 01:16:04,229 --> 01:16:03,360 that's not a sonification that's a sound 1957 01:16:07,110 --> 01:16:04,239 hearing the 1958 01:16:08,790 --> 01:16:07,120 the water pouring that's a sound so this 1959 01:16:11,510 --> 01:16:08,800 these 1960 01:16:12,470 --> 01:16:11,520 lines between sonification and sounds um 1961 01:16:15,830 --> 01:16:12,480 can be 1962 01:16:19,910 --> 01:16:15,840 especially when you get to um you know 1963 01:16:21,510 --> 01:16:19,920 a sound that is a real sound but isn't 1964 01:16:23,270 --> 01:16:21,520 actually audible to the human ear 1965 01:16:25,189 --> 01:16:23,280 being moved into a range that the human 1966 01:16:27,830 --> 01:16:25,199 ear can hear it because 1967 01:16:29,110 --> 01:16:27,840 it's its sound but you wouldn't have 1968 01:16:31,350 --> 01:16:29,120 been able to hear it without this 1969 01:16:33,430 --> 01:16:31,360 additional sonification component 1970 01:16:35,910 --> 01:16:33,440 such as the uh black hole merging the 1971 01:16:38,709 --> 01:16:35,920 chirp right 1972 01:16:40,229 --> 01:16:38,719 yeah yeah that's a perfect example yep 1973 01:16:42,310 --> 01:16:40,239 and the ekg is great too because it's 1974 01:16:43,990 --> 01:16:42,320 representing heartbeats 1975 01:16:45,590 --> 01:16:44,000 as sounds not actually listening to 1976 01:16:48,630 --> 01:16:45,600 sounds of the heart makes yeah 1977 01:16:50,470 --> 01:16:48,640 right so 1978 01:16:52,149 --> 01:16:50,480 the question that that's that i know 1979 01:16:52,790 --> 01:16:52,159 some of our audience has is is this 1980 01:16:54,790 --> 01:16:52,800 going to move 1981 01:16:56,470 --> 01:16:54,800 from doing sort of public outreach and 1982 01:16:58,790 --> 01:16:56,480 getting people to understand and 1983 01:17:01,350 --> 01:16:58,800 appreciate it to actually doing research 1984 01:17:02,310 --> 01:17:01,360 so will we ever have jody foster sitting 1985 01:17:04,630 --> 01:17:02,320 out with her 1986 01:17:05,990 --> 01:17:04,640 headphones on listening to the sounds of 1987 01:17:07,669 --> 01:17:06,000 the stuff listening to 1988 01:17:09,350 --> 01:17:07,679 the radio signals and actually doing 1989 01:17:11,510 --> 01:17:09,360 analysis which of course 1990 01:17:13,350 --> 01:17:11,520 never could happen because but for many 1991 01:17:14,470 --> 01:17:13,360 many reasons but what do you guys think 1992 01:17:17,110 --> 01:17:14,480 yeah i love contact 1993 01:17:18,070 --> 01:17:17,120 that's a great question and um we have 1994 01:17:20,950 --> 01:17:18,080 that now 1995 01:17:22,149 --> 01:17:20,960 so one important point of the project is 1996 01:17:23,990 --> 01:17:22,159 our goal is to make 1997 01:17:25,990 --> 01:17:24,000 sonification that is useful for research 1998 01:17:27,669 --> 01:17:26,000 purposes a lot of people make 1999 01:17:28,470 --> 01:17:27,679 sonification for things like press 2000 01:17:31,189 --> 01:17:28,480 releases 2001 01:17:33,990 --> 01:17:31,199 or presentations or art exhibits and 2002 01:17:37,590 --> 01:17:34,000 they really massage and change the sound 2003 01:17:39,189 --> 01:17:37,600 to be you know a certain 2004 01:17:40,870 --> 01:17:39,199 representation that works well for their 2005 01:17:43,030 --> 01:17:40,880 particular case but 2006 01:17:45,030 --> 01:17:43,040 our software is designed to enable real 2007 01:17:46,470 --> 01:17:45,040 research guts and everything so 2008 01:17:47,910 --> 01:17:46,480 if it sounds ugly because the data is 2009 01:17:49,270 --> 01:17:47,920 ugly we need to make sure that's 2010 01:17:51,189 --> 01:17:49,280 maintained and 2011 01:17:53,189 --> 01:17:51,199 we are also this is a very important 2012 01:17:56,070 --> 01:17:53,199 point we are working one-on-one 2013 01:17:58,149 --> 01:17:56,080 with many blind and low-vision 2014 01:17:59,750 --> 01:17:58,159 participants who are testing and giving 2015 01:18:02,070 --> 01:17:59,760 us feedback 2016 01:18:02,790 --> 01:18:02,080 on our project so we do have you know 2017 01:18:04,630 --> 01:18:02,800 several 2018 01:18:06,070 --> 01:18:04,640 blind low vision you know astronomy 2019 01:18:07,910 --> 01:18:06,080 students physics students computer 2020 01:18:09,510 --> 01:18:07,920 science students from around the world 2021 01:18:10,950 --> 01:18:09,520 working with us to make sure that this 2022 01:18:13,270 --> 01:18:10,960 is not only 2023 01:18:14,709 --> 01:18:13,280 a good portrayal of research data but 2024 01:18:15,990 --> 01:18:14,719 also something that's useful for them 2025 01:18:18,390 --> 01:18:16,000 because that's ultimately what this is 2026 01:18:19,830 --> 01:18:18,400 for not for us that was something that 2027 01:18:21,430 --> 01:18:19,840 came up very clearly 2028 01:18:23,430 --> 01:18:21,440 through some of the usability testing 2029 01:18:25,910 --> 01:18:23,440 i've been doing but 2030 01:18:28,070 --> 01:18:25,920 one person in particular who i think had 2031 01:18:29,669 --> 01:18:28,080 studied science in college but ended up 2032 01:18:30,950 --> 01:18:29,679 not being able to enter the field 2033 01:18:32,790 --> 01:18:30,960 because she was blind and 2034 01:18:34,630 --> 01:18:32,800 there's just too many barriers for her 2035 01:18:36,070 --> 01:18:34,640 so she wasn't able to pursue it as a 2036 01:18:37,110 --> 01:18:36,080 career unfortunately 2037 01:18:39,590 --> 01:18:37,120 and so when i was going through this 2038 01:18:40,790 --> 01:18:39,600 usability testing with her and then 2039 01:18:42,870 --> 01:18:40,800 at first she didn't realize she was 2040 01:18:45,750 --> 01:18:42,880 thinking it was these massaged uh 2041 01:18:46,630 --> 01:18:45,760 outreach style sonifications but when 2042 01:18:48,229 --> 01:18:46,640 once she like 2043 01:18:50,550 --> 01:18:48,239 realized that this was software that she 2044 01:18:53,590 --> 01:18:50,560 would be able to use to generate 2045 01:18:55,990 --> 01:18:53,600 the the sonifications herself it like 2046 01:18:57,110 --> 01:18:56,000 she's so excited because that means you 2047 01:18:58,149 --> 01:18:57,120 can do research 2048 01:19:00,550 --> 01:18:58,159 if you're listening to something 2049 01:19:01,910 --> 01:19:00,560 someone's already massaged that means 2050 01:19:03,189 --> 01:19:01,920 that all the research has kind of been 2051 01:19:04,870 --> 01:19:03,199 done right like anything 2052 01:19:06,790 --> 01:19:04,880 there is to know about that is probably 2053 01:19:08,229 --> 01:19:06,800 known by the person who put that 2054 01:19:09,590 --> 01:19:08,239 sonification out there 2055 01:19:11,910 --> 01:19:09,600 but the fact that we built this as 2056 01:19:13,189 --> 01:19:11,920 software means that people can sonify 2057 01:19:15,270 --> 01:19:13,199 their own data 2058 01:19:16,310 --> 01:19:15,280 and study it and then do re real 2059 01:19:18,229 --> 01:19:16,320 research with it 2060 01:19:20,790 --> 01:19:18,239 so that is the thing to really focus on 2061 01:19:24,229 --> 01:19:20,800 here this is enabling research 2062 01:19:25,510 --> 01:19:24,239 and one specific um use that came up in 2063 01:19:28,070 --> 01:19:25,520 another usability 2064 01:19:29,189 --> 01:19:28,080 test that jen did was with a current 2065 01:19:30,950 --> 01:19:29,199 undergraduate 2066 01:19:33,430 --> 01:19:30,960 who said that something that she'd been 2067 01:19:35,750 --> 01:19:33,440 struggling with she's working 2068 01:19:36,709 --> 01:19:35,760 on looking at actually light curve data 2069 01:19:40,709 --> 01:19:36,719 like what we're 2070 01:19:43,030 --> 01:19:40,719 using was that 2071 01:19:44,790 --> 01:19:43,040 they were running it through a pipeline 2072 01:19:46,310 --> 01:19:44,800 process you know and and doing their 2073 01:19:48,070 --> 01:19:46,320 analysis on it 2074 01:19:49,750 --> 01:19:48,080 and she would do that and then someone 2075 01:19:51,350 --> 01:19:49,760 who is sighted would come in and look at 2076 01:19:52,470 --> 01:19:51,360 the light curve and say well that that 2077 01:19:55,830 --> 01:19:52,480 light curve clearly has 2078 01:19:57,030 --> 01:19:55,840 problems and she couldn't tell and she 2079 01:20:00,070 --> 01:19:57,040 was like well with this 2080 01:20:01,830 --> 01:20:00,080 like they would they wouldn't 2081 01:20:03,590 --> 01:20:01,840 she was like well if i could sonify it 2082 01:20:05,189 --> 01:20:03,600 then i could listen to it and 2083 01:20:07,430 --> 01:20:05,199 you know i wouldn't i would still have 2084 01:20:09,830 --> 01:20:07,440 to go through the 2085 01:20:11,430 --> 01:20:09,840 analysis that's what the research is but 2086 01:20:11,830 --> 01:20:11,440 we're able to be able to do that check 2087 01:20:15,990 --> 01:20:11,840 that 2088 01:20:16,950 --> 01:20:16,000 bring up the light curving you can and 2089 01:20:19,430 --> 01:20:16,960 you go oh well that's 2090 01:20:20,470 --> 01:20:19,440 clearly garbage because it just doesn't 2091 01:20:22,149 --> 01:20:20,480 look real 2092 01:20:23,510 --> 01:20:22,159 um you know and that wasn't accessible 2093 01:20:25,830 --> 01:20:23,520 to her but you would be able to hear 2094 01:20:28,870 --> 01:20:25,840 that because it would just sound 2095 01:20:31,189 --> 01:20:28,880 weird and different and and so that you 2096 01:20:32,709 --> 01:20:31,199 know is maybe not as exciting as jody 2097 01:20:33,350 --> 01:20:32,719 foster being like oh i've discovered 2098 01:20:35,590 --> 01:20:33,360 aliens 2099 01:20:37,510 --> 01:20:35,600 but that's an important use case because 2100 01:20:39,990 --> 01:20:37,520 it's these mundane things 2101 01:20:41,910 --> 01:20:40,000 that make everyday research harder is 2102 01:20:44,790 --> 01:20:41,920 like when you realize you just spent an 2103 01:20:46,310 --> 01:20:44,800 hour running a you know piece of data 2104 01:20:47,590 --> 01:20:46,320 through a pipeline that's useless 2105 01:20:49,669 --> 01:20:47,600 because the data was 2106 01:20:50,950 --> 01:20:49,679 bad to begin with i mean we all do that 2107 01:20:52,470 --> 01:20:50,960 when we 2108 01:20:53,910 --> 01:20:52,480 have everything at our fingertips 2109 01:20:54,629 --> 01:20:53,920 imagine how often you do that when 2110 01:20:59,270 --> 01:20:54,639 you're 2111 01:21:02,790 --> 01:21:01,750 and um do you guys have any ideas of 2112 01:21:05,110 --> 01:21:02,800 possibly 2113 01:21:07,110 --> 01:21:05,120 you know citizen science oh sourcing it 2114 01:21:08,470 --> 01:21:07,120 for these huge data sets that might need 2115 01:21:10,390 --> 01:21:08,480 to be sonified 2116 01:21:11,990 --> 01:21:10,400 that because it sounds like you could 2117 01:21:14,790 --> 01:21:12,000 train the public to listen 2118 01:21:15,510 --> 01:21:14,800 for certain things and identify you know 2119 01:21:16,790 --> 01:21:15,520 because 2120 01:21:18,310 --> 01:21:16,800 you know citizen science is great for 2121 01:21:19,270 --> 01:21:18,320 looking for those needles in a haystack 2122 01:21:21,189 --> 01:21:19,280 and if you can 2123 01:21:22,550 --> 01:21:21,199 uh train people you have any thoughts on 2124 01:21:24,629 --> 01:21:22,560 that on that front 2125 01:21:26,390 --> 01:21:24,639 yeah one of the things one of the 2126 01:21:27,990 --> 01:21:26,400 projects in the back of my mind is to 2127 01:21:29,189 --> 01:21:28,000 make a test dot radio 2128 01:21:31,270 --> 01:21:29,199 i don't know if people would be 2129 01:21:32,709 --> 01:21:31,280 interested in it but uh i've been 2130 01:21:33,750 --> 01:21:32,719 thinking about well we can create and 2131 01:21:35,910 --> 01:21:33,760 make it interesting 2132 01:21:37,590 --> 01:21:35,920 we can maybe make a spotify channel just 2133 01:21:38,390 --> 01:21:37,600 plays all these light curves so i'm 2134 01:21:40,950 --> 01:21:38,400 actually working 2135 01:21:42,229 --> 01:21:40,960 today on preparing to release something 2136 01:21:44,149 --> 01:21:42,239 like 19 2137 01:21:46,629 --> 01:21:44,159 million light curves from the test 2138 01:21:49,430 --> 01:21:46,639 mission 19 million stars 2139 01:21:50,229 --> 01:21:49,440 and no one ever will be able to look at 2140 01:21:54,550 --> 01:21:50,239 them 2141 01:21:56,870 --> 01:21:54,560 listen to some while we're working or in 2142 01:21:57,910 --> 01:21:56,880 the car or taking a shower or whatever 2143 01:21:59,510 --> 01:21:57,920 we might be able to make some really 2144 01:22:00,790 --> 01:21:59,520 cool discoveries so yeah there's there's 2145 01:22:02,229 --> 01:22:00,800 people there are also other groups 2146 01:22:03,750 --> 01:22:02,239 looking at um xenoverse 2147 01:22:05,750 --> 01:22:03,760 a lot of our audience might be familiar 2148 01:22:07,590 --> 01:22:05,760 with xenoverse um there's at least one 2149 01:22:09,590 --> 01:22:07,600 or two groups looking to incorporate 2150 01:22:10,790 --> 01:22:09,600 sound as a xenoverse project and we 2151 01:22:12,629 --> 01:22:10,800 could do the same thing as well 2152 01:22:14,310 --> 01:22:12,639 if there's interest and resources to do 2153 01:22:14,790 --> 01:22:14,320 so yeah we really want to engage the 2154 01:22:16,229 --> 01:22:14,800 public 2155 01:22:18,390 --> 01:22:16,239 and also i think there was a question 2156 01:22:20,390 --> 01:22:18,400 about um being able to 2157 01:22:22,070 --> 01:22:20,400 um contribute if you know if you know 2158 01:22:23,910 --> 01:22:22,080 software this is open source 2159 01:22:25,510 --> 01:22:23,920 so if if you really want to get in 2160 01:22:26,709 --> 01:22:25,520 interested in a volunteer basis and you 2161 01:22:28,229 --> 01:22:26,719 know how to code 2162 01:22:29,990 --> 01:22:28,239 it's open source you can do a pull 2163 01:22:31,510 --> 01:22:30,000 request um it's 2164 01:22:36,470 --> 01:22:31,520 we're open for business as it were but 2165 01:22:39,590 --> 01:22:38,310 we're open for science we're open to 2166 01:22:41,350 --> 01:22:39,600 science and contribution and 2167 01:22:44,070 --> 01:22:41,360 collaboration that's what it's all about 2168 01:22:45,030 --> 01:22:44,080 okay um clara there was a question that 2169 01:22:47,990 --> 01:22:45,040 uh sort of 2170 01:22:48,390 --> 01:22:48,000 asked about what would i programming 2171 01:22:50,870 --> 01:22:48,400 thing 2172 01:22:52,310 --> 01:22:50,880 skills do i need to do astronomy and 2173 01:22:54,870 --> 01:22:52,320 i've actually gotten that question 2174 01:22:55,350 --> 01:22:54,880 a lot from when i give career talks for 2175 01:22:59,430 --> 01:22:55,360 for 2176 01:23:01,990 --> 01:22:59,440 do astronomy stuff 2177 01:23:03,110 --> 01:23:02,000 you're you're doing python um can you 2178 01:23:04,790 --> 01:23:03,120 just uh 2179 01:23:06,709 --> 01:23:04,800 give an idea of what people would want 2180 01:23:09,270 --> 01:23:06,719 to study in terms of these the 2181 01:23:11,270 --> 01:23:09,280 programming languages and why 2182 01:23:12,470 --> 01:23:11,280 yeah i mean so if you want to get into 2183 01:23:14,470 --> 01:23:12,480 astronomy 2184 01:23:15,669 --> 01:23:14,480 definitely python is a great place to 2185 01:23:19,669 --> 01:23:15,679 start i mean i 2186 01:23:21,189 --> 01:23:19,679 recommend people interested to get into 2187 01:23:22,310 --> 01:23:21,199 i recommend that people start with 2188 01:23:23,830 --> 01:23:22,320 python when they're starting with 2189 01:23:26,870 --> 01:23:23,840 programming languages 2190 01:23:29,590 --> 01:23:26,880 and i recommend this for 2191 01:23:31,350 --> 01:23:29,600 basically one very important reason 2192 01:23:33,189 --> 01:23:31,360 which is that it is an incredibly 2193 01:23:36,070 --> 01:23:33,199 popular language and there is an 2194 01:23:37,830 --> 01:23:36,080 abundance of information about doing 2195 01:23:40,629 --> 01:23:37,840 things in python on the internet 2196 01:23:43,030 --> 01:23:40,639 i noticed this very much i'm a i'm a 2197 01:23:46,229 --> 01:23:43,040 python programmer and i'm a c programmer 2198 01:23:47,350 --> 01:23:46,239 and i can vary and i'm very good at both 2199 01:23:49,430 --> 01:23:47,360 of those languages 2200 01:23:51,430 --> 01:23:49,440 and i can easily get myself into a 2201 01:23:53,510 --> 01:23:51,440 situation and see 2202 01:23:55,510 --> 01:23:53,520 where i've hit a problem and i go to the 2203 01:23:57,590 --> 01:23:55,520 internet and i can't find anything 2204 01:23:59,189 --> 01:23:57,600 and i just have to sort of bust my way 2205 01:24:00,950 --> 01:23:59,199 through it and i'm experienced enough 2206 01:24:04,229 --> 01:24:00,960 now that i can do it 2207 01:24:05,990 --> 01:24:04,239 but i've almost never got myself in that 2208 01:24:07,910 --> 01:24:06,000 situation with python 2209 01:24:09,350 --> 01:24:07,920 even with the really weird complicated 2210 01:24:10,870 --> 01:24:09,360 things there's someone else who has done 2211 01:24:11,189 --> 01:24:10,880 it and it was put it on the internet and 2212 01:24:15,510 --> 01:24:11,199 that 2213 01:24:18,149 --> 01:24:15,520 makes learning it a incredibly 2214 01:24:19,990 --> 01:24:18,159 more rewarding experience and then the 2215 01:24:21,750 --> 01:24:20,000 other thing for astronomy particularly 2216 01:24:24,950 --> 01:24:21,760 if you're not 2217 01:24:26,310 --> 01:24:24,960 currently in school in a traditional 2218 01:24:28,310 --> 01:24:26,320 physics program with a lot of people 2219 01:24:30,390 --> 01:24:28,320 around you is there is a nice 2220 01:24:31,669 --> 01:24:30,400 astronomical community built around 2221 01:24:32,950 --> 01:24:31,679 software 2222 01:24:35,110 --> 01:24:32,960 if you're interested in getting into 2223 01:24:37,990 --> 01:24:35,120 things i recommend checking out astro pi 2224 01:24:39,110 --> 01:24:38,000 it's the main python package for 2225 01:24:40,950 --> 01:24:39,120 astronomy 2226 01:24:42,390 --> 01:24:40,960 but more than that it is also an 2227 01:24:44,390 --> 01:24:42,400 ecosystem there is 2228 01:24:45,430 --> 01:24:44,400 a it's a great community they run 2229 01:24:48,070 --> 01:24:45,440 community events 2230 01:24:49,030 --> 01:24:48,080 they run hack days they run hackathons 2231 01:24:51,430 --> 01:24:49,040 some of which 2232 01:24:53,189 --> 01:24:51,440 they run workshops that are really in 2233 01:24:55,189 --> 01:24:53,199 invest and they're really invested in 2234 01:24:57,189 --> 01:24:55,199 bringing people into the community 2235 01:24:58,709 --> 01:24:57,199 they have an extensive tagging system on 2236 01:25:00,950 --> 01:24:58,719 their issues so you can look for things 2237 01:25:03,270 --> 01:25:00,960 that are easy 2238 01:25:05,430 --> 01:25:03,280 they have a whole astropyler network 2239 01:25:08,390 --> 01:25:05,440 that that helps you learn 2240 01:25:09,030 --> 01:25:08,400 how to use astrophy but it can also 2241 01:25:12,790 --> 01:25:09,040 teach you 2242 01:25:16,070 --> 01:25:12,800 a lot about astronomy 2243 01:25:18,070 --> 01:25:16,080 i have an undergraduate degree in 2244 01:25:19,750 --> 01:25:18,080 astronomy and now i have more experience 2245 01:25:21,750 --> 01:25:19,760 in astronomy but when i started working 2246 01:25:24,870 --> 01:25:21,760 at space telescope my python abilities 2247 01:25:28,950 --> 01:25:24,880 outstripped my astronomy abilities 2248 01:25:31,350 --> 01:25:28,960 and so i would go to these tutorials and 2249 01:25:33,270 --> 01:25:31,360 and yeah i you know they're teaching me 2250 01:25:35,030 --> 01:25:33,280 how to manipulate tables and how to use 2251 01:25:36,709 --> 01:25:35,040 this particular astro pi package but 2252 01:25:38,470 --> 01:25:36,719 that wasn't really the hard part for me 2253 01:25:42,229 --> 01:25:38,480 they were also teaching me 2254 01:25:45,350 --> 01:25:42,239 you know how to 2255 01:25:47,430 --> 01:25:45,360 um analyze a star 2256 01:25:48,950 --> 01:25:47,440 how to analyze a spectra how to do all 2257 01:25:50,310 --> 01:25:48,960 these different things so i think that's 2258 01:25:52,229 --> 01:25:50,320 a really great place to start there are 2259 01:25:54,390 --> 01:25:52,239 other languages that are useful 2260 01:25:56,390 --> 01:25:54,400 for astronomy but the barrier to entry 2261 01:25:58,709 --> 01:25:56,400 is lower for python and you'll get to 2262 01:26:00,390 --> 01:25:58,719 interact with astronomers basically as 2263 01:26:01,990 --> 01:26:00,400 soon as you want to 2264 01:26:05,030 --> 01:26:02,000 and that's a great point about the 2265 01:26:07,110 --> 01:26:05,040 software ecosystem that enables science 2266 01:26:08,790 --> 01:26:07,120 uh there's so much you know more than 2267 01:26:10,629 --> 01:26:08,800 just you know everyone thinks of 2268 01:26:12,310 --> 01:26:10,639 astronomers looking at using the 2269 01:26:15,590 --> 01:26:12,320 telescope and getting data 2270 01:26:16,629 --> 01:26:15,600 uh there's such an amazing uh ecosystem 2271 01:26:18,229 --> 01:26:16,639 of of 2272 01:26:19,669 --> 01:26:18,239 other things that have to happen to make 2273 01:26:22,629 --> 01:26:19,679 science happen 2274 01:26:23,270 --> 01:26:22,639 i think it would be tutorials out there 2275 01:26:25,270 --> 01:26:23,280 that use 2276 01:26:28,229 --> 01:26:25,280 actual astronomical data from those 2277 01:26:31,510 --> 01:26:28,239 telescopes so it can also be a quick way 2278 01:26:33,910 --> 01:26:31,520 to get to see the same data that all of 2279 01:26:35,830 --> 01:26:33,920 the astronomers are looking at 2280 01:26:37,750 --> 01:26:35,840 all right we're getting close to 9 30. 2281 01:26:40,390 --> 01:26:37,760 grant is there any one last question or 2282 01:26:42,149 --> 01:26:40,400 or do you think we're done here we are 2283 01:26:45,350 --> 01:26:42,159 through the questions that the 2284 01:26:47,830 --> 01:26:45,360 chat has and yeah 2285 01:26:50,629 --> 01:26:47,840 i just think scott if you wouldn't mind 2286 01:26:52,070 --> 01:26:50,639 just dropping some of the links 2287 01:26:54,470 --> 01:26:52,080 or the because there's some people 2288 01:26:58,229 --> 01:26:54,480 asking about astro pie and whatnot 2289 01:27:00,790 --> 01:26:58,239 oh yeah i will remember that there are 2290 01:27:01,990 --> 01:27:00,800 like for this lecture there are 2291 01:27:04,950 --> 01:27:02,000 thousands of people 2292 01:27:06,550 --> 01:27:04,960 all over the world doing this sort of 2293 01:27:08,310 --> 01:27:06,560 stuff and they would love nothing more 2294 01:27:09,430 --> 01:27:08,320 than for you to help explore space with 2295 01:27:12,550 --> 01:27:09,440 them like 2296 01:27:15,669 --> 01:27:12,560 become a part of something awesome 2297 01:27:17,270 --> 01:27:15,679 yeah so like there's no 2298 01:27:19,270 --> 01:27:17,280 there's no upfront there's no getting 2299 01:27:20,709 --> 01:27:19,280 into it you
