1 00:00:06,650 --> 00:00:03,770 today and so my question is how do you 2 00:00:09,950 --> 00:00:06,660 avoid bilking and the answer comes from 3 00:00:12,440 --> 00:00:09,960 information entropy entropy has two 4 00:00:15,560 --> 00:00:12,450 forms the classical form is 5 00:00:17,710 --> 00:00:15,570 thermodynamics and at a previous SS a 6 00:00:20,300 --> 00:00:17,720 meeting I talked about this 7 00:00:22,910 --> 00:00:20,310 thermodynamic entropy and discussed how 8 00:00:25,130 --> 00:00:22,920 it can be used with regard to Sian 9 00:00:26,720 --> 00:00:25,140 formation there's another form of 10 00:00:28,580 --> 00:00:26,730 entropy and that is information entropy 11 00:00:31,659 --> 00:00:28,590 and that is the entropy that I'm going 12 00:00:33,889 --> 00:00:31,669 to be using today and it has been shown 13 00:00:36,160 --> 00:00:33,899 pretty much conclusively that 14 00:00:41,030 --> 00:00:36,170 information entropy is in fact identical 15 00:00:43,880 --> 00:00:41,040 to thermodynamic entropy so again this 16 00:00:46,000 --> 00:00:43,890 is a measure of disorder this 17 00:00:48,110 --> 00:00:46,010 information entropy can be expressed 18 00:00:50,930 --> 00:00:48,120 quantitatively and you can express it in 19 00:00:53,689 --> 00:00:50,940 terms of how surprised you are to learn 20 00:00:56,299 --> 00:00:53,699 that an intended outcome has occurred 21 00:01:01,580 --> 00:00:56,309 and that's called surprise elitsa 22 00:01:03,470 --> 00:01:01,590 technical term so if you know little it 23 00:01:08,179 --> 00:01:03,480 really is I didn't make it up if you 24 00:01:10,730 --> 00:01:08,189 know little about the outcome and it 25 00:01:12,380 --> 00:01:10,740 occurs then you will be very surprised 26 00:01:16,460 --> 00:01:12,390 if you know a lot you'll be less 27 00:01:18,140 --> 00:01:16,470 surprised and so this surprise ille is a 28 00:01:22,340 --> 00:01:18,150 measure of uncertainty and it's 29 00:01:24,200 --> 00:01:22,350 quantified in terms of entropy and so if 30 00:01:26,840 --> 00:01:24,210 you know little beforehand the 31 00:01:29,030 --> 00:01:26,850 information entropy is large and it 32 00:01:31,760 --> 00:01:29,040 turns out that in this case the 33 00:01:35,780 --> 00:01:31,770 possibility of retro psychokinesis is 34 00:01:39,289 --> 00:01:35,790 large this has been described and can be 35 00:01:42,999 --> 00:01:39,299 described quantitatively using entropy 36 00:01:46,219 --> 00:01:43,009 and surprise ille in information entropy 37 00:01:47,960 --> 00:01:46,229 an information theory involving 38 00:01:52,039 --> 00:01:47,970 Shannon's famous formula I'm not going 39 00:01:55,160 --> 00:01:52,049 to go into that right now so what are 40 00:01:58,959 --> 00:01:55,170 the implications of this approach in 41 00:02:02,179 --> 00:01:58,969 which we say that in fact you can have 42 00:02:06,469 --> 00:02:02,189 retro causation it does not contradict 43 00:02:09,460 --> 00:02:06,479 physics under certain conditions well we 44 00:02:11,360 --> 00:02:09,470 can say that retro causation is 45 00:02:13,670 --> 00:02:11,370 compatible and I haven't gone into that 46 00:02:16,309 --> 00:02:13,680 here with Newton's laws and 47 00:02:18,679 --> 00:02:16,319 of energy and I can say that the real 48 00:02:22,670 --> 00:02:18,689 question is one of the second law of 49 00:02:25,160 --> 00:02:22,680 thermodynamics and entropy is a vector 50 00:02:27,170 --> 00:02:25,170 causation compatible with that and I 51 00:02:30,050 --> 00:02:27,180 think that really is the question and 52 00:02:32,179 --> 00:02:30,060 that's how it ought to be posed why the 53 00:02:35,330 --> 00:02:32,189 second law of thermodynamics because the 54 00:02:38,809 --> 00:02:35,340 second law of thermodynamics is really 55 00:02:43,270 --> 00:02:38,819 just a description of logic it describes 56 00:02:47,740 --> 00:02:43,280 logically how a multi-part system by a 57 00:02:52,399 --> 00:02:47,750 probability must evolve over time so 58 00:02:55,490 --> 00:02:52,409 what I've done is I've linked logic from 59 00:03:00,140 --> 00:02:55,500 the second law of thermodynamics and the 60 00:03:04,009 --> 00:03:00,150 bilking paradox to produce what are the 61 00:03:06,649 --> 00:03:04,019 conditions for retro causation and we 62 00:03:10,429 --> 00:03:06,659 find that it's not not an all-or-nothing 63 00:03:13,819 --> 00:03:10,439 process but in fact it's a it's a part 64 00:03:17,270 --> 00:03:13,829 as a somewhat process and the greater 65 00:03:20,319 --> 00:03:17,280 our knowledge of a previous outcome the 66 00:03:22,939 --> 00:03:20,329 smaller the information entropy is and 67 00:03:26,479 --> 00:03:22,949 the smaller the interim information 68 00:03:29,349 --> 00:03:26,489 entropy is the less of an effect we can 69 00:03:31,849 --> 00:03:29,359 have on the past the lower our 70 00:03:35,270 --> 00:03:31,859 psychokinesis efficiency if we can 71 00:03:39,830 --> 00:03:35,280 define such a quantity so the bilking 72 00:03:42,349 --> 00:03:39,840 paradox disappears if psychokinesis is 73 00:03:46,249 --> 00:03:42,359 limited by uncertainty and that 74 00:03:49,670 --> 00:03:46,259 uncertainty is measured by information 75 00:03:52,490 --> 00:03:49,680 entropy and looking at it a little bit 76 00:03:54,979 --> 00:03:52,500 more in terms of quantities that we deal 77 00:03:57,499 --> 00:03:54,989 with every day in life it's limited by 78 00:04:00,530 --> 00:03:57,509 noise because the more noise that a 79 00:04:02,629 --> 00:04:00,540 system has the greater the entropy the 80 00:04:07,550 --> 00:04:02,639 information entropy is and the greater 81 00:04:10,670 --> 00:04:07,560 the psychokinesis can be and it this is 82 00:04:13,670 --> 00:04:10,680 consistent with other musings and 83 00:04:16,009 --> 00:04:13,680 studies which have linked sigh phenomena 84 00:04:18,319 --> 00:04:16,019 to noise in a system if you have a 85 00:04:22,850 --> 00:04:18,329 perfectly defined system with no 86 00:04:25,200 --> 00:04:22,860 randomness associated with noise then we 87 00:04:41,790 --> 00:04:25,210 cannot have a sigh phenomena 88 00:04:49,469 --> 00:04:44,159 I was afraid of a question from York and 89 00:04:53,240 --> 00:04:49,479 here it comes some speculations by the 90 00:04:58,730 --> 00:04:53,250 late philosopher Robert Nozick about the 91 00:05:01,379 --> 00:04:58,740 the way truth values are related to time 92 00:05:05,430 --> 00:05:01,389 suggest an alternative scenario in which 93 00:05:07,890 --> 00:05:05,440 it is possible to win yesterday's 94 00:05:14,909 --> 00:05:07,900 lottery even after you already know the 95 00:05:17,279 --> 00:05:14,919 wrong ticket that if a retro PK can 96 00:05:20,100 --> 00:05:17,289 actually operate it would be in 97 00:05:23,700 --> 00:05:20,110 principle possible using Nozick's model 98 00:05:25,680 --> 00:05:23,710 that you make your PK effort you change 99 00:05:29,010 --> 00:05:25,690 this event in the past and then all 100 00:05:31,320 --> 00:05:29,020 causal carlitz change ah in which case 101 00:05:33,180 --> 00:05:31,330 you would find yourself completely 102 00:05:35,700 --> 00:05:33,190 forgetting everything that had happened 103 00:05:38,189 --> 00:05:35,710 before and you would simply have been 104 00:05:39,749 --> 00:05:38,199 holding the winning lottery ticket the 105 00:05:42,869 --> 00:05:39,759 whole time and there would be no point 106 00:05:45,839 --> 00:05:42,879 in this case of using the retro PK this 107 00:05:50,129 --> 00:05:45,849 is not a that this is not an internal 108 00:05:52,800 --> 00:05:50,139 contradiction because the of the way 109 00:05:55,890 --> 00:05:52,810 Nozick's truth values are handled and 110 00:05:59,040 --> 00:05:55,900 I'm wondering if you'd like to comment 111 00:06:01,969 --> 00:05:59,050 on this approach ok so that is one of a 112 00:06:04,350 --> 00:06:01,979 class of several philosophical 113 00:06:06,980 --> 00:06:04,360 descriptions of ways that you can 114 00:06:11,249 --> 00:06:06,990 uncaused something in the past to happen 115 00:06:13,860 --> 00:06:11,259 retro actively and I find them to be 116 00:06:16,140 --> 00:06:13,870 highly artificial and I see no 117 00:06:18,990 --> 00:06:16,150 experimental evidence for them it 118 00:06:21,089 --> 00:06:19,000 doesn't seem to relate in any way to 119 00:06:25,529 --> 00:06:21,099 what I understand is house I phenomena 120 00:06:28,920 --> 00:06:25,539 occur and although I think they're nice 121 00:06:30,510 --> 00:06:28,930 mind candy I don't think that they help 122 00:06:34,800 --> 00:06:30,520 us in understanding what's happening 123 00:06:37,529 --> 00:06:34,810 here so Garrett as a as a practical 124 00:06:39,480 --> 00:06:37,539 matter in doing this when you start 125 00:06:42,689 --> 00:06:39,490 thinking about picking the six numbers 126 00:06:45,689 --> 00:06:42,699 of the lottery out of the pool of 40 or 127 00:06:47,249 --> 00:06:45,699 so numbers doesn't I aren't those 128 00:06:49,350 --> 00:06:47,259 completely independent events and the 129 00:06:51,329 --> 00:06:49,360 knowledge of one really shouldn't have 130 00:06:52,950 --> 00:06:51,339 any effect on the on the others it just 131 00:06:55,350 --> 00:06:52,960 basically reduces the probability 132 00:06:58,740 --> 00:06:55,360 the of picking a one in 40 versus the 133 00:07:01,320 --> 00:06:58,750 next numbers of one and 39 so I'm not 134 00:07:04,529 --> 00:07:01,330 sure it's if you think about it as each 135 00:07:07,230 --> 00:07:04,539 each prediction or each information 136 00:07:10,260 --> 00:07:07,240 exchange is it is a independent event 137 00:07:12,570 --> 00:07:10,270 unless you're saying that you're at well 138 00:07:14,159 --> 00:07:12,580 those leave it there Darryl I think your 139 00:07:17,700 --> 00:07:14,169 point is well taken and particularly 140 00:07:19,830 --> 00:07:17,710 after my response to York and saying 141 00:07:22,290 --> 00:07:19,840 that York's examples were unrealistic 142 00:07:26,129 --> 00:07:22,300 you're pointing out that my example 2 is 143 00:07:28,499 --> 00:07:26,139 unrealistic and I agree with you 144 00:07:30,629 --> 00:07:28,509 actually the lottery example I put it up 145 00:07:33,570 --> 00:07:30,639 there because the numbers give us a good 146 00:07:35,939 --> 00:07:33,580 mechanism to kind of think how much of 147 00:07:37,890 --> 00:07:35,949 something do we know but I agree with 148 00:07:39,510 --> 00:07:37,900 you that there are problems with the 149 00:07:41,460 --> 00:07:39,520 lottery example and if we want to talk 150 00:07:42,900 --> 00:07:41,470 about a real example it would have to be 151 00:07:44,909 --> 00:07:42,910 some sort of a fuzziness of 152 00:07:46,770 --> 00:07:44,919 understanding an image or something like 153 00:07:49,230 --> 00:07:46,780 that where we've gotten certain parts of 154 00:07:51,629 --> 00:07:49,240 it so your point is well taken hey 155 00:07:53,249 --> 00:07:51,639 Garrett um I'm kind of going to ask a 156 00:07:56,060 --> 00:07:53,259 similar question to everybody else but 157 00:07:58,260 --> 00:07:56,070 then as everyone else but isn't there a 158 00:08:00,120 --> 00:07:58,270 can you always kind of have a broader 159 00:08:02,969 --> 00:08:00,130 system around the system that you're in 160 00:08:05,129 --> 00:08:02,979 where for example it turns out that your 161 00:08:07,140 --> 00:08:05,139 lottery information was a mistake or you 162 00:08:11,730 --> 00:08:07,150 misheard it or just kind of on and on 163 00:08:13,110 --> 00:08:11,740 and aren't those sort of things wouldn't 164 00:08:17,790 --> 00:08:13,120 they be governed by the same sorts of 165 00:08:20,640 --> 00:08:17,800 rules in a way so this mistake I I 166 00:08:24,300 --> 00:08:20,650 actually need a response from John this 167 00:08:26,820 --> 00:08:24,310 mistake is it part of the noise of a 168 00:08:32,519 --> 00:08:26,830 larger system or is it separate from the 169 00:08:34,500 --> 00:08:32,529 noise of a larger system you can always 170 00:08:35,519 --> 00:08:34,510 have a larger system effectively I mean 171 00:08:37,170 --> 00:08:35,529 at the end of the day you could keep 172 00:08:38,760 --> 00:08:37,180 working through these systems and then 173 00:08:40,920 --> 00:08:38,770 you could come upon an observation and 174 00:08:43,019 --> 00:08:40,930 say oh my god and then just wake up 175 00:08:46,019 --> 00:08:43,029 effectively so you know that's a silly 176 00:08:47,850 --> 00:08:46,029 philosophical way of looking at it but I 177 00:08:50,370 --> 00:08:47,860 don't know that we can talk about a 178 00:08:52,410 --> 00:08:50,380 system that's totally isolated including 179 00:08:54,720 --> 00:08:52,420 I agree with you and this is really a 180 00:08:56,340 --> 00:08:54,730 flaw of the law the second law of 181 00:08:58,410 --> 00:08:56,350 thermodynamics which says that you're 182 00:09:00,269 --> 00:08:58,420 dealing with a closed system and the 183 00:09:01,860 --> 00:09:00,279 entropy within that closed system act in 184 00:09:05,369 --> 00:09:01,870 a certain way and you're saying that 185 00:09:06,539 --> 00:09:05,379 really no system is closed and I agree
