1 00:00:04,160 --> 00:00:06,480 Hello, and welcome to the physics world stories 2 00:00:06,480 --> 00:00:10,400 podcast. I'm Andrew Glaston. And on physicsworld.com, 3 00:00:10,400 --> 00:00:13,315 you'll be able to find the quantum briefing. 4 00:00:13,375 --> 00:00:14,894 As we will do in this episode of 5 00:00:14,894 --> 00:00:15,554 the podcast, 6 00:00:15,855 --> 00:00:18,435 it explores some of the most amazing stories 7 00:00:18,495 --> 00:00:21,214 from the past, present, and future of quantum 8 00:00:21,214 --> 00:00:21,714 mechanics, 9 00:00:22,975 --> 00:00:25,774 including the link between quantum physics and the 10 00:00:25,774 --> 00:00:29,670 Cheshire cat and possibility that, and stay tuned 11 00:00:29,670 --> 00:00:32,649 for this, we might be able to influence 12 00:00:32,789 --> 00:00:33,530 the past. 13 00:00:34,950 --> 00:00:36,789 That's all to come, but on the front 14 00:00:36,789 --> 00:00:39,909 cover of the physics world quantum briefing was 15 00:00:39,909 --> 00:00:42,310 a wonderful piece of art inspired by quantum 16 00:00:42,310 --> 00:00:44,844 mechanics that I wanted to know more about, 17 00:00:44,844 --> 00:00:47,504 and there's quite a story behind its creation. 18 00:00:47,884 --> 00:00:50,545 So here, to start today's podcast, 19 00:00:50,924 --> 00:00:52,784 is the person behind it. 20 00:00:53,564 --> 00:00:56,445 My name's Felicity Inkpen. I'm an artist. I 21 00:00:56,445 --> 00:00:57,504 used to be a scientist. 22 00:00:57,969 --> 00:00:59,189 Academia was 23 00:00:59,810 --> 00:01:02,289 not for me, and I think that's the 24 00:01:02,289 --> 00:01:03,829 experience of a lot of scientists. 25 00:01:05,010 --> 00:01:07,090 I was heartbroken about it because I I 26 00:01:07,090 --> 00:01:10,129 love science, and I built my world around 27 00:01:10,129 --> 00:01:12,034 it. I built my life around it. But 28 00:01:12,034 --> 00:01:13,954 I guess I felt quite lucky in that 29 00:01:13,954 --> 00:01:15,554 I had always always had this, 30 00:01:16,114 --> 00:01:18,034 twin passion of the art. And I've been 31 00:01:18,034 --> 00:01:19,715 making art my entire life since I was 32 00:01:19,715 --> 00:01:21,734 a tiny little girl. So 33 00:01:22,594 --> 00:01:25,314 when I finally made the heartbreaking decision to 34 00:01:25,314 --> 00:01:25,954 leave academia, 35 00:01:27,840 --> 00:01:30,560 I just wanted to paint. And my plan 36 00:01:30,560 --> 00:01:32,959 was I'll just paint and see how far 37 00:01:32,959 --> 00:01:34,799 I can go. And that was a few 38 00:01:34,799 --> 00:01:36,560 years ago. And that was just over three 39 00:01:36,560 --> 00:01:38,799 years ago. And I've been making a lot 40 00:01:38,799 --> 00:01:40,959 of science inspired art because it turns out 41 00:01:40,959 --> 00:01:42,479 when you leave academia, it doesn't mean you 42 00:01:42,479 --> 00:01:43,424 stop loving science. 43 00:01:45,984 --> 00:01:46,805 So the 44 00:01:47,105 --> 00:01:49,825 is everything you do science inspired? No. No. 45 00:01:49,825 --> 00:01:50,625 Not at all. 46 00:01:52,064 --> 00:01:54,965 You know, as an artist, you're trying to 47 00:01:55,905 --> 00:01:56,385 explore 48 00:01:57,025 --> 00:01:58,530 you know, when I, when I first quit 49 00:01:58,769 --> 00:02:00,209 science to, to do the art, I didn't 50 00:02:00,209 --> 00:02:01,729 know what kind of artist I wanted to 51 00:02:01,729 --> 00:02:04,209 be. There's very many different ways in which 52 00:02:04,209 --> 00:02:05,829 to be an artist. And 53 00:02:06,609 --> 00:02:08,689 I had a period of play, which I 54 00:02:08,689 --> 00:02:11,569 highly recommend. Like people should just take a 55 00:02:11,569 --> 00:02:13,455 little bit of time out and play and 56 00:02:13,455 --> 00:02:15,614 figure out what makes them happy. Really enjoyed 57 00:02:15,614 --> 00:02:16,114 that. 58 00:02:16,735 --> 00:02:17,235 And 59 00:02:18,974 --> 00:02:21,694 I have been making, you know, various different 60 00:02:21,694 --> 00:02:23,534 works, but I kept on finding that I 61 00:02:23,534 --> 00:02:25,314 kept on coming back to the science. 62 00:02:26,040 --> 00:02:27,640 I had one piece. So the first painting 63 00:02:27,640 --> 00:02:30,300 that I painted after I quit, the lab 64 00:02:30,439 --> 00:02:32,920 was a painting called synesthesia counting by numbers. 65 00:02:32,920 --> 00:02:34,120 Would you like me to chat about that 66 00:02:34,120 --> 00:02:36,460 a little bit? And Yes, please. Yes. 67 00:02:37,240 --> 00:02:37,640 So, 68 00:02:38,439 --> 00:02:39,980 I have number color synesthesia. 69 00:02:40,335 --> 00:02:42,175 What that means is I see all numbers 70 00:02:42,175 --> 00:02:44,495 as colors. I didn't know that other people 71 00:02:44,495 --> 00:02:46,194 didn't see numbers as colors. 72 00:02:46,814 --> 00:02:47,635 It was only 73 00:02:47,935 --> 00:02:50,094 a conversation with colleagues that led me to 74 00:02:50,094 --> 00:02:52,094 discover this when we were just talking about 75 00:02:52,094 --> 00:02:53,775 what happens in your head when you multiply 76 00:02:53,775 --> 00:02:56,159 two numbers together. And one person said, oh, 77 00:02:56,159 --> 00:02:56,900 I see, 78 00:02:57,360 --> 00:02:59,680 a square getting larger. And somebody else saw 79 00:02:59,680 --> 00:03:01,620 it said, I saw a line getting longer. 80 00:03:01,680 --> 00:03:03,520 And I was like, what are you talking 81 00:03:03,520 --> 00:03:05,219 about? Don't you just see the colors? 82 00:03:05,919 --> 00:03:08,080 And they went, oh, you're the weird one 83 00:03:08,080 --> 00:03:08,900 in this conversation. 84 00:03:10,905 --> 00:03:11,405 So, 85 00:03:12,185 --> 00:03:14,985 when I sat down in my art studio 86 00:03:14,985 --> 00:03:17,145 to paint my first kind of painting of, 87 00:03:17,145 --> 00:03:19,164 like, I am a full time artist now, 88 00:03:19,305 --> 00:03:21,705 it was just a painting of numbers. So 89 00:03:21,705 --> 00:03:24,419 I painted the numbers, one to a 24 90 00:03:24,500 --> 00:03:26,740 because that's 32 squared. And, you know, 32 91 00:03:26,740 --> 00:03:28,580 is beautiful because it's green and it's pink 92 00:03:28,580 --> 00:03:29,699 and it's yellow and it's got a little 93 00:03:29,699 --> 00:03:31,300 bit of blue in it because it's two 94 00:03:31,300 --> 00:03:32,900 to the power of five as well as 95 00:03:32,900 --> 00:03:35,379 being four times eight and the digits three 96 00:03:35,379 --> 00:03:36,039 and two. 97 00:03:36,500 --> 00:03:37,000 And 98 00:03:37,594 --> 00:03:38,814 that painting definitely, 99 00:03:39,594 --> 00:03:41,454 set me on a particular trajectory 100 00:03:42,474 --> 00:03:42,974 because 101 00:03:43,435 --> 00:03:46,254 it was such an important conduit for conversations. 102 00:03:46,715 --> 00:03:49,114 And that was definitely something in terms of 103 00:03:49,114 --> 00:03:51,674 finding my place as a artist inspired by 104 00:03:51,674 --> 00:03:53,969 science, because I was I I realized this 105 00:03:53,969 --> 00:03:56,050 is what art is for. I can have 106 00:03:56,050 --> 00:03:56,550 conversations 107 00:03:57,169 --> 00:03:58,710 because of this painting existing 108 00:03:59,250 --> 00:04:00,710 that I could never have before. 109 00:04:01,169 --> 00:04:03,889 And they might be kept conversations with somebody 110 00:04:03,889 --> 00:04:05,490 who wants into my studio. It might be 111 00:04:05,490 --> 00:04:08,710 conversations with a neuroscientist who specializes in synesthesia. 112 00:04:10,665 --> 00:04:12,284 All these different ways 113 00:04:13,305 --> 00:04:14,125 of generating 114 00:04:14,504 --> 00:04:15,004 questions 115 00:04:16,504 --> 00:04:18,365 through communicating something visually. 116 00:04:19,305 --> 00:04:21,084 And that feels like 117 00:04:21,629 --> 00:04:23,810 what I'm supposed to be doing right now 118 00:04:23,949 --> 00:04:26,270 is taking the strangest ideas and all of 119 00:04:26,270 --> 00:04:28,670 the kind of benefit and the knowledge and 120 00:04:28,670 --> 00:04:30,030 the love that I have of of my 121 00:04:30,030 --> 00:04:31,090 career in science 122 00:04:31,629 --> 00:04:35,150 and creating it or channeling it into visual 123 00:04:35,150 --> 00:04:35,650 images 124 00:04:37,164 --> 00:04:38,064 that that communicate 125 00:04:39,084 --> 00:04:41,964 those strange ideas and allow people who wouldn't 126 00:04:41,964 --> 00:04:45,004 necessarily feel that science was something accessible to 127 00:04:45,004 --> 00:04:46,764 them to say, oh, I know exactly what 128 00:04:46,764 --> 00:04:49,084 you mean. Because now I've seen that image, 129 00:04:49,084 --> 00:04:50,865 I can describe something that I 130 00:04:51,379 --> 00:04:53,319 experienced or something that I've thought 131 00:04:53,699 --> 00:04:54,919 or something that, 132 00:04:56,019 --> 00:04:58,360 I don't know, I've I've experimented with. 133 00:04:59,620 --> 00:05:02,360 So that painting was very, very key, and 134 00:05:03,459 --> 00:05:03,824 it's, 135 00:05:04,384 --> 00:05:06,465 you know, I loved painting. I loved being 136 00:05:06,625 --> 00:05:08,944 it didn't feel like it was mine. That's 137 00:05:08,944 --> 00:05:10,705 that's another really fun thing about being an 138 00:05:10,705 --> 00:05:13,504 artist. Sometimes you're painting something and you don't 139 00:05:13,504 --> 00:05:15,745 feel like, oh, I'm the creator. You feel 140 00:05:15,745 --> 00:05:17,365 like this painting already existed. 141 00:05:18,064 --> 00:05:19,125 Just the lucky 142 00:05:20,040 --> 00:05:22,600 individual that it gets channeled through, who gets 143 00:05:22,600 --> 00:05:24,040 to be the one to create it and 144 00:05:24,040 --> 00:05:25,959 then talk about it later. And I definitely 145 00:05:25,959 --> 00:05:27,740 felt that about that particular painting. 146 00:05:29,560 --> 00:05:31,720 So I it's central because you've mentioned that, 147 00:05:31,720 --> 00:05:33,720 you know, strange ideas. And the reason we're 148 00:05:33,720 --> 00:05:35,685 talking is because you've done the the front 149 00:05:35,685 --> 00:05:37,764 cover of the quantum briefing for physics world, 150 00:05:37,764 --> 00:05:39,125 which we will get to. But I just 151 00:05:39,125 --> 00:05:41,764 wanna, you know, to pick apart a couple 152 00:05:41,764 --> 00:05:42,564 of things there. Because you've 153 00:05:44,324 --> 00:05:46,485 when you had that initial conversation, then they 154 00:05:46,485 --> 00:05:48,344 were, you know, you're the strange one. 155 00:05:48,870 --> 00:05:49,850 It's a conversation. 156 00:05:50,550 --> 00:05:52,709 Presumably, through your art, you've met more people 157 00:05:52,709 --> 00:05:55,750 who have the same sort of experiences as 158 00:05:55,750 --> 00:05:58,490 you do. Absolutely. And I think, 159 00:05:59,029 --> 00:06:01,430 you know, one thing so I used to 160 00:06:01,430 --> 00:06:02,329 be a neuroscientist, 161 00:06:03,584 --> 00:06:04,084 and, 162 00:06:05,504 --> 00:06:06,884 found out about aphantasia, 163 00:06:07,345 --> 00:06:08,785 which is when people have a lack of 164 00:06:08,785 --> 00:06:09,685 a visual imagination. 165 00:06:10,384 --> 00:06:10,884 And, 166 00:06:12,785 --> 00:06:14,785 I I think if there's a spectrum, I'm 167 00:06:14,785 --> 00:06:16,785 probably more on the other end of it 168 00:06:16,785 --> 00:06:17,845 as, like, a hypofantasia 169 00:06:18,480 --> 00:06:19,680 kind of person. I know that they were 170 00:06:19,680 --> 00:06:22,720 doing research at Exeter University about a sort 171 00:06:22,720 --> 00:06:25,060 of spectrum between aphantasia and hypofantasia. 172 00:06:27,600 --> 00:06:31,279 And that's an example of something where you 173 00:06:31,279 --> 00:06:31,779 realize 174 00:06:32,495 --> 00:06:35,375 through talk through creating images and through talking 175 00:06:35,375 --> 00:06:37,854 about your process of creating images that not 176 00:06:37,854 --> 00:06:40,034 everybody has the same internal, 177 00:06:40,334 --> 00:06:41,474 you know, way of of, 178 00:06:42,334 --> 00:06:45,055 experiencing the world. The but we will take 179 00:06:45,055 --> 00:06:46,194 for granted our, 180 00:06:46,814 --> 00:06:49,529 perception. We will assume that everybody else has 181 00:06:49,529 --> 00:06:50,750 the exact same perception 182 00:06:51,689 --> 00:06:52,589 and that, 183 00:06:53,529 --> 00:06:55,449 you know, if you say imagine an apple, 184 00:06:55,449 --> 00:06:55,949 I 185 00:06:56,490 --> 00:06:58,009 see what I see, and I imagine that 186 00:06:58,009 --> 00:06:59,849 everybody else sees exactly the same thing that 187 00:06:59,849 --> 00:07:01,449 I see.

Well, and this week I've been messing 230 00:08:24,319 --> 00:08:26,959 around with ink and thinking about the sizes 231 00:08:26,959 --> 00:08:29,514 of molecules and how that changes how ink 232 00:08:29,514 --> 00:08:31,214 moves across a piece of paper 233 00:08:32,235 --> 00:08:33,834 and how I can make that into a 234 00:08:33,834 --> 00:08:35,754 piece of art that I like. You said 235 00:08:35,754 --> 00:08:38,394 32 is particular colors. Is it always those 236 00:08:38,394 --> 00:08:40,315 colors? Yeah. Yeah. Yeah. Yeah. So, 237 00:08:41,595 --> 00:08:43,950 I mean, everybody who has number color synesthesia 238 00:08:44,009 --> 00:08:45,370 is gonna see something different. And it is 239 00:08:45,370 --> 00:08:47,049 funny because sometimes you come across other people 240 00:08:47,049 --> 00:08:49,129 with number color synesthesia, and they'll you get 241 00:08:49,129 --> 00:08:51,210 into arguments about, like, you know, I was 242 00:08:51,210 --> 00:08:53,450 saying, obviously, four is yellow. And they're like, 243 00:08:53,450 --> 00:08:55,309 what are you talking about? Four is green. 244 00:08:58,434 --> 00:08:59,735 So for me personally, 245 00:09:00,754 --> 00:09:03,075 prime numbers tend to be quite flat and 246 00:09:03,075 --> 00:09:03,815 quite earthy. 247 00:09:04,995 --> 00:09:07,235 And then a number that has lots of 248 00:09:07,235 --> 00:09:10,534 factors tends to be multicolored and very vibrant. 249 00:09:11,269 --> 00:09:11,769 So, 250 00:09:12,629 --> 00:09:15,769 24 would be a very colorful number. 251 00:09:16,309 --> 00:09:17,750 It's got all of the you know, the 252 00:09:17,750 --> 00:09:18,710 the colors of, 253 00:09:19,429 --> 00:09:21,190 it's got yellow and red and orange and 254 00:09:21,190 --> 00:09:23,990 green because it's it's three times eight, and 255 00:09:23,990 --> 00:09:26,309 it's four times six. So the factors of 256 00:09:26,309 --> 00:09:26,809 it 257 00:09:27,404 --> 00:09:27,884 create, 258 00:09:28,365 --> 00:09:29,584 the mixture of colors. 259 00:09:29,884 --> 00:09:31,264 Whereas the number 17 260 00:09:31,725 --> 00:09:33,745 is quite a boring mauve. 261 00:09:34,524 --> 00:09:35,024 And, 262 00:09:36,684 --> 00:09:39,325 but that's, that's my personal, you know, that's 263 00:09:39,325 --> 00:09:41,259 just for me. Yeah. But it is really 264 00:09:41,259 --> 00:09:44,080 interesting then thinking about how we conceptualize numbers 265 00:09:44,139 --> 00:09:45,740 because for me, it's always, 266 00:09:47,019 --> 00:09:48,540 being just like a joy to see the 267 00:09:48,540 --> 00:09:50,220 patterns and the way the numbers relate to 268 00:09:50,220 --> 00:09:51,920 one another. So, like, 269 00:09:53,100 --> 00:09:55,754 multiples of four are always going to have 270 00:09:55,754 --> 00:09:57,835 that bit of yellow. So they're always going 271 00:09:57,835 --> 00:10:00,495 to have that little callback to, don't forget 272 00:10:01,115 --> 00:10:02,735 there's a four in here somewhere. 273 00:10:03,434 --> 00:10:03,934 And, 274 00:10:04,794 --> 00:10:06,634 you know, that's it's a very useful and 275 00:10:06,634 --> 00:10:09,460 and beautiful way of of seeing numbers and 276 00:10:09,460 --> 00:10:10,680 then thinking about mathematics. 277 00:10:12,180 --> 00:10:14,340 And it is a fun thing to explore. 278 00:10:14,340 --> 00:10:16,519 I did a a the the second synesthesia 279 00:10:16,660 --> 00:10:18,420 painting I did was a painting of prime 280 00:10:18,420 --> 00:10:20,034 numbers, and I didn't know what it was 281 00:10:20,034 --> 00:10:21,235 going to look like. I sort of you 282 00:10:21,235 --> 00:10:23,154 know, I I knew what the prime numbers 283 00:10:23,154 --> 00:10:25,174 up to a certain amount looked like roughly 284 00:10:25,235 --> 00:10:26,134 in my head. 285 00:10:27,154 --> 00:10:28,434 But, you know, you get into the larger 286 00:10:28,434 --> 00:10:30,674 prime numbers. And and what came back is 287 00:10:30,674 --> 00:10:32,450 it was yeah, the colors of, like, the 288 00:10:32,450 --> 00:10:34,850 earth kept on coming up. And I was 289 00:10:34,850 --> 00:10:36,070 like, oh, that's interesting. 290 00:10:37,089 --> 00:10:39,009 They're all quite flat, but they're all quite 291 00:10:39,009 --> 00:10:39,509 earthy. 292 00:10:41,009 --> 00:10:42,309 So that was, yeah, 293 00:10:42,929 --> 00:10:44,070 a a joy to discover. 294 00:10:45,485 --> 00:10:47,485 It so it helps with the maths as 295 00:10:47,485 --> 00:10:49,425 well as sort of helping with the art. 296 00:10:49,485 --> 00:10:49,985 Absolutely. 297 00:10:51,805 --> 00:10:54,125 I was one of those nerdy kids in 298 00:10:54,125 --> 00:10:56,605 school that really loved maths. I couldn't get 299 00:10:56,605 --> 00:10:57,419 enough of maths. 300 00:10:58,779 --> 00:11:00,860 I wouldn't you know, I'm I'm definitely not 301 00:11:00,860 --> 00:11:03,100 particularly mathematically talented. I have a great many 302 00:11:03,100 --> 00:11:05,579 friends who are much more mathematically talented than 303 00:11:05,579 --> 00:11:06,879 I would ever be, but, 304 00:11:07,980 --> 00:11:09,899 but I definitely had a a a great 305 00:11:09,899 --> 00:11:12,185 deal of love for maths. And I I 306 00:11:12,185 --> 00:11:14,285 struggle to understand why other people 307 00:11:14,985 --> 00:11:16,365 in my class at school 308 00:11:17,065 --> 00:11:17,565 didn't 309 00:11:18,425 --> 00:11:20,105 see how beautiful it was to that, you 310 00:11:20,105 --> 00:11:21,865 know, they seemed to struggle with it maybe 311 00:11:21,865 --> 00:11:23,545 a bit more than I did. And then 312 00:11:23,545 --> 00:11:26,289 after realizing that not everybody else see sees 313 00:11:26,289 --> 00:11:28,370 colors, I was like, oh, well, maths would 314 00:11:28,370 --> 00:11:30,289 be really boring and really dull if it 315 00:11:30,289 --> 00:11:31,830 wasn't colorful.

Do the colors translate 394 00:14:36,754 --> 00:14:38,534 back into numbers if you see? 395 00:14:39,475 --> 00:14:41,814 No. It's a it's it's a sad answer. 396 00:14:42,689 --> 00:14:44,929 It's it it doesn't really go back the 397 00:14:44,929 --> 00:14:46,449 other way. The color is just the color. 398 00:14:46,449 --> 00:14:46,949 It's 399 00:14:47,490 --> 00:14:49,809 the number that has the concept and the 400 00:14:49,809 --> 00:14:50,309 patterns. 401 00:14:50,850 --> 00:14:52,149 It's, you know, the the 402 00:14:52,929 --> 00:14:55,544 a kinda a number like 256, 403 00:14:55,784 --> 00:14:56,445 for example, 404 00:14:57,065 --> 00:14:57,884 that is 405 00:14:58,504 --> 00:15:01,144 beautifully bright and vibrant and colorful because of 406 00:15:01,144 --> 00:15:03,304 the factors that make it. Mhmm. So it 407 00:15:03,304 --> 00:15:05,704 is the the patterns that are drawing all 408 00:15:05,704 --> 00:15:06,764 these colors together. 409 00:15:07,625 --> 00:15:10,139 Whereas a color kind of stands alone as 410 00:15:10,139 --> 00:15:11,339 itself. I mean, I can I can look 411 00:15:11,339 --> 00:15:12,699 at something and be like, oh, well, that 412 00:15:12,699 --> 00:15:13,360 would be, 413 00:15:14,459 --> 00:15:15,279 I don't know, 414 00:15:15,659 --> 00:15:17,759 3,403? 415 00:15:17,819 --> 00:15:20,159 I'm looking at my glasses case right now. 416 00:15:22,059 --> 00:15:23,995 But, you know, it's not like the color 417 00:15:23,995 --> 00:15:26,975 of my glasses case has that intrinsic feeling 418 00:15:27,434 --> 00:15:30,014 of a number. Mhmm. It's the the numbers 419 00:15:30,074 --> 00:15:32,814 and the the beautiful patterns and the elements 420 00:15:32,875 --> 00:15:35,595 and the factors that contribute to how that 421 00:15:35,595 --> 00:15:37,800 number relates to other numbers. It's colorful. 422 00:15:38,500 --> 00:15:39,879 So you were drawn 423 00:15:40,259 --> 00:15:42,340 to maths and physics, and that's where you 424 00:15:42,340 --> 00:15:43,940 sort of studied first of all. Is it 425 00:15:44,180 --> 00:15:46,899 was was the weird world of quantum something 426 00:15:46,899 --> 00:15:48,920 that drew you? Oh, absolutely. And, 427 00:15:49,779 --> 00:15:52,985 I had wonderful quantum physics lecturers. So I 428 00:15:52,985 --> 00:15:55,785 studied my undergrad at, the University of Leeds, 429 00:15:55,785 --> 00:15:56,285 and 430 00:15:56,825 --> 00:15:58,125 they at that time, 431 00:15:58,585 --> 00:15:59,865 they had a I don't know if it's 432 00:15:59,865 --> 00:16:01,965 still there, but they had a really wonderful 433 00:16:02,024 --> 00:16:02,924 quantum computing, 434 00:16:05,705 --> 00:16:07,379 bit lab, whatever you call it. 435 00:16:09,220 --> 00:16:10,200 So it wasn't 436 00:16:10,580 --> 00:16:13,539 just, like, learning about quantum. It was learning 437 00:16:13,539 --> 00:16:15,779 about quantum or people who are really passionate 438 00:16:15,779 --> 00:16:17,779 about it and who were at the the 439 00:16:17,779 --> 00:16:20,295 forefront of science and who were so engaging 440 00:16:20,355 --> 00:16:23,095 and able to really communicate it well. 441 00:16:24,195 --> 00:16:24,695 I 442 00:16:25,554 --> 00:16:27,554 went to study physics. Like, I think, like 443 00:16:27,554 --> 00:16:28,295 many physicists, 444 00:16:29,715 --> 00:16:31,095 I wanted to be an astrophysicist. 445 00:16:31,970 --> 00:16:33,809 I wanted to study nebula. That was my 446 00:16:33,809 --> 00:16:35,169 kind of thought going into it as a 447 00:16:35,169 --> 00:16:35,669 teenager. 448 00:16:36,129 --> 00:16:36,629 And 449 00:16:36,929 --> 00:16:37,429 after 450 00:16:37,809 --> 00:16:40,129 a year's worth of astrophysics modules, I was 451 00:16:40,129 --> 00:16:41,429 like, you know what? Astrophysics, 452 00:16:41,809 --> 00:16:43,269 not for me, not my favorite. 453 00:16:44,784 --> 00:16:46,304 Not to say I didn't love it, and 454 00:16:46,304 --> 00:16:48,464 I still, you know, I still love the 455 00:16:48,464 --> 00:16:50,544 stars, of course. How could you not? But, 456 00:16:51,345 --> 00:16:53,345 I found the the type of physics I 457 00:16:53,345 --> 00:16:56,625 really enjoyed was thermodynamics and statistical mechanics and 458 00:16:56,625 --> 00:16:59,365 the physics of gloop and complex fluids and 459 00:16:59,480 --> 00:17:01,980 and jelly and colloids and things like that, 460 00:17:03,000 --> 00:17:04,460 and eventually biophysics, 461 00:17:05,240 --> 00:17:09,080 which then lent itself towards the transition into 462 00:17:09,080 --> 00:17:11,160 neuroscience, which happened later. There was a kind 463 00:17:11,160 --> 00:17:13,080 of a period of about four years when 464 00:17:13,080 --> 00:17:16,384 I worked in different jobs before I eventually 465 00:17:16,384 --> 00:17:17,904 decided I I wanted to go back to 466 00:17:17,904 --> 00:17:18,404 science. 467 00:17:19,825 --> 00:17:20,325 But, 468 00:17:21,105 --> 00:17:23,744 yeah, the the I was glad to have 469 00:17:23,744 --> 00:17:25,044 a really well rounded, 470 00:17:25,505 --> 00:17:27,204 physics education as an undergrad. 471 00:17:28,464 --> 00:17:30,085 And quantum's amazing, 472 00:17:30,900 --> 00:17:31,400 obviously. 473 00:17:32,180 --> 00:17:33,859 How can you, like, how can you learn 474 00:17:33,859 --> 00:17:36,740 about quantum and not just be fundamentally changed 475 00:17:36,740 --> 00:17:39,220 as a person after after learning about it? 476 00:17:39,220 --> 00:17:42,740 I remember this particular lecture where our first 477 00:17:42,740 --> 00:17:45,875 year physics lecturer brought us the whole way 478 00:17:45,875 --> 00:17:48,515 through a derivation and kept on checking and 479 00:17:48,515 --> 00:17:49,714 being like, we all agree with it. Right? 480 00:17:49,714 --> 00:17:51,234 And you got a 100 students all nodding 481 00:17:51,234 --> 00:17:52,674 being like, yeah, we're all following this. We're 482 00:17:52,674 --> 00:17:55,234 all following this. And then the kind of 483 00:17:55,234 --> 00:17:56,294 conclusion was, 484 00:17:57,474 --> 00:17:57,974 therefore, 485 00:17:58,355 --> 00:17:59,174 many universes. 486 00:18:00,910 --> 00:18:03,070 And you kind of had a 100 people 487 00:18:03,070 --> 00:18:05,470 who've all been following this derivation, following the 488 00:18:05,470 --> 00:18:07,230 maps the whole way through, agreeing with it 489 00:18:07,230 --> 00:18:09,630 with every step, and then being like, yeah. 490 00:18:09,630 --> 00:18:11,414 I can't really argue with that. 491 00:18:13,575 --> 00:18:15,734 I I had a friend, a physicist friend 492 00:18:15,734 --> 00:18:17,115 visit just this weekend. 493 00:18:17,494 --> 00:18:17,994 And, 494 00:18:19,414 --> 00:18:21,095 this physicist friend that I studied with as 495 00:18:21,095 --> 00:18:21,755 an undergraduate 496 00:18:22,055 --> 00:18:24,295 doesn't work in physics anymore, works in data 497 00:18:24,295 --> 00:18:24,690 science. 498 00:18:25,809 --> 00:18:28,129 And she and I were talking about how 499 00:18:28,129 --> 00:18:29,429 you're never not a physicist. 500 00:18:30,369 --> 00:18:32,609 Like, even though it was, you know, our 501 00:18:32,609 --> 00:18:35,509 undergraduate years, we still have that identity 502 00:18:36,129 --> 00:18:37,429 so kind of fundamentally 503 00:18:37,865 --> 00:18:39,625 in ourselves. And I think, you know, quantum 504 00:18:39,625 --> 00:18:40,825 has a a big role to play in 505 00:18:40,825 --> 00:18:41,325 that. 506 00:18:42,744 --> 00:18:44,365 Yeah. So you have, 507 00:18:45,224 --> 00:18:48,125 created the front cover of the quantum briefing 508 00:18:48,184 --> 00:18:49,224 for physics world. 509 00:18:49,545 --> 00:18:51,065 Perhaps we could look at that as a 510 00:18:51,065 --> 00:18:51,724 sort of 511 00:18:52,789 --> 00:18:55,990 example of your creative process. Maybe talk us 512 00:18:55,990 --> 00:18:58,390 through what how that came to you. And 513 00:18:58,630 --> 00:19:00,710 Well, I was delighted to get the commission, 514 00:19:00,710 --> 00:19:03,589 and the commission was, can you paint a 515 00:19:03,589 --> 00:19:05,414 picture of quantum mechanics that's, 516 00:19:06,695 --> 00:19:09,894 beautiful and colorful and original and not something 517 00:19:09,894 --> 00:19:10,955 that we've seen before? 518 00:19:11,975 --> 00:19:14,455 So no cats in boxes or anything like 519 00:19:14,455 --> 00:19:14,955 that. 520 00:19:16,775 --> 00:19:17,275 And, 521 00:19:18,455 --> 00:19:20,075 obviously, that's slightly daunting. 522 00:19:22,190 --> 00:19:24,850 My process when it comes to art is 523 00:19:26,190 --> 00:19:28,590 often it goes back to experimentation and play. 524 00:19:28,590 --> 00:19:30,910 And, actually, I sort of see experimentation and 525 00:19:30,910 --> 00:19:32,190 play as kind of one and the same 526 00:19:32,190 --> 00:19:32,690 thing. 527 00:19:33,070 --> 00:19:33,570 The, 528 00:19:35,615 --> 00:19:37,134 I will go into my studio and I'll 529 00:19:37,134 --> 00:19:38,974 see what art materials I have around, and 530 00:19:38,974 --> 00:19:40,275 I will just start 531 00:19:40,654 --> 00:19:41,555 messing about, 532 00:19:41,934 --> 00:19:44,255 messing about like a kid. And then sort 533 00:19:44,255 --> 00:19:46,015 of thinking what would happen if? What would 534 00:19:46,015 --> 00:19:46,835 happen if? 535 00:19:47,535 --> 00:19:48,674 So I'd already, 536 00:19:49,940 --> 00:19:52,580 started this series of works, which were just 537 00:19:52,580 --> 00:19:53,720 exploring how 538 00:19:54,019 --> 00:19:56,580 how different pigments move, which had all started 539 00:19:56,580 --> 00:19:58,180 when I was just washing my brush. I 540 00:19:58,180 --> 00:19:59,700 was washing my some ink off of my 541 00:19:59,700 --> 00:20:02,580 paintbrush in some water, and I was like, 542 00:20:02,580 --> 00:20:05,045 oh, I like that. I like the way 543 00:20:05,045 --> 00:20:06,505 the ink moves in the water. 544 00:20:06,805 --> 00:20:09,125 And then that led to more and more 545 00:20:09,125 --> 00:20:10,265 elaborate setups, 546 00:20:10,724 --> 00:20:14,025 adding in bigger glasses, different inks, different pigments, 547 00:20:14,724 --> 00:20:17,704 different lighting setups, getting myself a UV torch, 548 00:20:17,809 --> 00:20:19,569 buying a big spaghetti jar because that I 549 00:20:19,569 --> 00:20:21,349 could fill the whole way up with water. 550 00:20:23,169 --> 00:20:23,669 So 551 00:20:23,970 --> 00:20:26,210 I was thinking about, right, how could you 552 00:20:26,210 --> 00:20:28,210 represent quantum mechanics? And I'm I'm sort of, 553 00:20:28,210 --> 00:20:30,369 you know, going back and thinking about everything 554 00:20:30,369 --> 00:20:32,174 I'd loved about quantum mechanics. And 555 00:20:32,975 --> 00:20:35,075 and the a lot of it comes down 556 00:20:35,695 --> 00:20:36,355 to probability, 557 00:20:38,654 --> 00:20:40,654 the idea of many things being true at 558 00:20:40,654 --> 00:20:41,154 once 559 00:20:41,535 --> 00:20:42,015 and, 560 00:20:42,335 --> 00:20:44,015 being able to kind of prove that through 561 00:20:44,015 --> 00:20:44,515 interference. 562 00:20:46,059 --> 00:20:48,240 So I was thinking, how can I create, 563 00:20:48,700 --> 00:20:50,000 a plain full setup 564 00:20:50,700 --> 00:20:51,919 where I can see, 565 00:20:53,339 --> 00:20:56,720 different pigments, different inks interfering and coexisting 566 00:20:57,179 --> 00:20:58,275 in the same space? 567 00:20:58,994 --> 00:21:01,075 Maybe that will lead me to something that 568 00:21:01,075 --> 00:21:03,394 I feel starts to represent something to do 569 00:21:03,394 --> 00:21:04,375 with quantum mechanics. 570 00:21:06,275 --> 00:21:06,775 And 571 00:21:07,474 --> 00:21:08,214 what I, 572 00:21:08,515 --> 00:21:10,914 this is another like weird thing about being 573 00:21:10,914 --> 00:21:12,914 an artist. It's very hard to throw anything 574 00:21:12,914 --> 00:21:13,740 away, very 575 00:21:14,299 --> 00:21:16,160 because you're always like, that might be useful. 576 00:21:17,660 --> 00:21:19,980 So I had a bunch of expired printer 577 00:21:19,980 --> 00:21:20,480 cartridges, 578 00:21:21,660 --> 00:21:23,599 which had been sitting on my table, 579 00:21:24,380 --> 00:21:26,539 in a little dish. And I thought, right, 580 00:21:26,539 --> 00:21:28,214 maybe I can do something with these. 581 00:21:28,775 --> 00:21:29,414 And then, 582 00:21:30,855 --> 00:21:32,474 I thought it'd be really good 583 00:21:32,934 --> 00:21:34,075 if I could 584 00:21:34,615 --> 00:21:36,454 see how the ink flows out of the 585 00:21:36,454 --> 00:21:37,355 printer cartridges. 586 00:21:38,855 --> 00:21:39,355 But, 587 00:21:40,214 --> 00:21:41,255 I I first had tried it in my 588 00:21:41,255 --> 00:21:42,775 big spaghetti jar, and I thought, no. No. 589 00:21:42,775 --> 00:21:45,259 No. No. We need something shallow, wide and 590 00:21:45,259 --> 00:21:46,299 shallow. So I went off to the shop 591 00:21:46,299 --> 00:21:48,460 and bought myself a oven dish, came back, 592 00:21:48,460 --> 00:21:50,539 and I thought, how can I light this? 593 00:21:50,539 --> 00:21:51,980 It's really hard to light this. It'd be 594 00:21:51,980 --> 00:21:53,180 really good if I had a light box. 595 00:21:53,180 --> 00:21:54,460 I didn't have a light box, but what 596 00:21:54,460 --> 00:21:56,720 I did have was a seasonal affective disorder 597 00:21:56,779 --> 00:21:58,380 lamp, you know, one of these sort of 598 00:21:58,380 --> 00:22:01,115 flat lamps that kind of emits incredibly bright 599 00:22:01,115 --> 00:22:03,674 LED lights. So went and got that, put 600 00:22:03,674 --> 00:22:05,835 it underneath the oven dish, and then put 601 00:22:05,835 --> 00:22:07,835 my put some water in the oven dish, 602 00:22:07,835 --> 00:22:09,355 and then put the printer cartridges in. And 603 00:22:09,355 --> 00:22:10,634 then I was like, right. I like how 604 00:22:10,634 --> 00:22:12,234 they're moving, or I like how the ink 605 00:22:12,234 --> 00:22:14,174 is is moving out of that. 606 00:22:16,089 --> 00:22:17,769 But I think we can adapt how the 607 00:22:17,769 --> 00:22:19,609 ink moves a bit more. So then it 608 00:22:19,609 --> 00:22:20,750 was it was 609 00:22:21,049 --> 00:22:22,349 a a couple of days of 610 00:22:22,970 --> 00:22:24,109 intense play. 611 00:22:24,890 --> 00:22:26,670 I mean, like, getting really focused 612 00:22:27,565 --> 00:22:29,404 and experimenting with, like, what happens if I 613 00:22:29,404 --> 00:22:30,845 add a bit of salt? What happens if 614 00:22:30,845 --> 00:22:33,565 I make a really thin layer of water 615 00:22:33,565 --> 00:22:35,404 before I add main cartridges? What happens if 616 00:22:35,404 --> 00:22:38,225 I add this? Etcetera, etcetera, etcetera. So, eventually, 617 00:22:39,245 --> 00:22:40,465 two printer cartridges 618 00:22:41,009 --> 00:22:44,130 and a very thin layer of, like, 60% 619 00:22:44,130 --> 00:22:45,589 sugar, 40% water 620 00:22:45,890 --> 00:22:47,830 was the golden kind of, 621 00:22:49,490 --> 00:22:49,990 mixture. 622 00:22:50,450 --> 00:22:51,190 And then 623 00:22:51,570 --> 00:22:53,570 I basically, I just sit in my studio, 624 00:22:53,570 --> 00:22:55,605 and I I watch and I observe. And 625 00:22:55,605 --> 00:22:57,545 eventually, I'll go, oh, I like that. 626 00:22:57,924 --> 00:22:59,625 And take a quick photo 627 00:22:59,924 --> 00:23:01,525 or take a video if you're sort of 628 00:23:01,525 --> 00:23:02,744 trying to see the dynamics. 629 00:23:03,605 --> 00:23:04,744 And then from that, 630 00:23:05,845 --> 00:23:08,519 basically, start playing with the images, start playing 631 00:23:08,519 --> 00:23:10,779 with paints because then it's you know, 632 00:23:11,400 --> 00:23:13,180 I'm not a photographer. I'm a painter. 633 00:23:13,559 --> 00:23:15,880 I've created I've captured an image of a 634 00:23:15,880 --> 00:23:18,519 moment that can never be created again of 635 00:23:18,519 --> 00:23:19,259 of this 636 00:23:19,720 --> 00:23:21,960 this diffusion of dyes that I feel is 637 00:23:21,960 --> 00:23:24,704 is able to communicate something about, 638 00:23:26,204 --> 00:23:27,585 about, yeah, probability, 639 00:23:28,045 --> 00:23:28,525 about, 640 00:23:29,884 --> 00:23:32,384 states existing in the same place. But 641 00:23:33,005 --> 00:23:34,845 for me as an artist, that's it's not 642 00:23:34,845 --> 00:23:37,069 enough to stop there. I need 643 00:23:37,369 --> 00:23:38,990 to then have that engagement 644 00:23:39,369 --> 00:23:40,669 with it. So, 645 00:23:41,929 --> 00:23:44,569 yeah, once I have that that photograph, it's 646 00:23:44,569 --> 00:23:46,409 then how can I recreate this? And I 647 00:23:46,409 --> 00:23:48,089 love working with oil paints. Oh my gosh. 648 00:23:48,089 --> 00:23:49,529 Everybody should have a go playing with oil 649 00:23:49,529 --> 00:23:51,345 paints once you have, Unfortunately, you have to 650 00:23:51,345 --> 00:23:53,204 buy a bunch of, like, solvents and 651 00:23:53,984 --> 00:23:55,744 mediums and things like that, and they do 652 00:23:55,744 --> 00:23:57,984 take an absolute age to dry. But oil 653 00:23:57,984 --> 00:24:00,144 paints, oh, they're delicious. They're just so fun 654 00:24:00,144 --> 00:24:01,045 to paint with. 655 00:24:02,305 --> 00:24:05,149 So then it's going about, right, can you 656 00:24:05,210 --> 00:24:07,849 manipulate these oil paints on your on your, 657 00:24:08,329 --> 00:24:08,829 panel, 658 00:24:10,089 --> 00:24:11,769 in such a way that you feel is 659 00:24:11,769 --> 00:24:15,129 is managing to capture this spontaneous moment that 660 00:24:15,129 --> 00:24:16,750 you've captured in this photograph? 661 00:24:19,095 --> 00:24:20,535 So in some ways, it feels like it 662 00:24:20,535 --> 00:24:21,894 feels like a bit of a ruse or 663 00:24:21,894 --> 00:24:23,115 a bit of a luck that 664 00:24:23,894 --> 00:24:25,894 that I've taken a a couple of days 665 00:24:25,894 --> 00:24:27,035 of pure play, 666 00:24:27,894 --> 00:24:28,875 and out of 667 00:24:29,335 --> 00:24:31,734 it have, an image which is on the 668 00:24:31,734 --> 00:24:34,059 cover of the quantum briefing. You know, 669 00:24:34,440 --> 00:24:36,859 it it's what a great job I have. 670 00:24:37,160 --> 00:24:37,660 Okay. 671 00:24:39,480 --> 00:24:41,240 It's amazing.

And that's the importance 789 00:28:57,644 --> 00:29:00,204 of art is that sometimes you need to 790 00:29:00,204 --> 00:29:01,884 see something on a page in a book 791 00:29:01,884 --> 00:29:04,044 or in a performance or in a hear 792 00:29:04,044 --> 00:29:05,244 it in a song or see it in 793 00:29:05,244 --> 00:29:07,184 a painting before you're able to articulate, 794 00:29:07,769 --> 00:29:09,369 oh, this is how I feel about this 795 00:29:09,369 --> 00:29:11,369 thing, which, you know, going back to beginning 796 00:29:11,369 --> 00:29:14,330 our conversation is why the synesthesia painting has 797 00:29:14,330 --> 00:29:16,570 been so interesting because so many people have 798 00:29:16,570 --> 00:29:19,130 been able to articulate things that they'd never 799 00:29:19,130 --> 00:29:20,590 able to articulate before. 800 00:29:21,734 --> 00:29:24,134 My, I did a a art exhibition back 801 00:29:24,134 --> 00:29:25,275 in 2016, 802 00:29:25,654 --> 00:29:26,795 which was all about, 803 00:29:27,174 --> 00:29:29,735 a phenomenon phenomenon called lapel de vid or 804 00:29:29,735 --> 00:29:31,734 a call of the void, which if you've 805 00:29:31,734 --> 00:29:32,634 ever been 806 00:29:32,934 --> 00:29:34,615 up in some high place and you've had 807 00:29:34,615 --> 00:29:36,910 a little intrusive thought of, like, what would 808 00:29:36,910 --> 00:29:39,070 happen if I lent too far over this 809 00:29:39,070 --> 00:29:39,570 railing? 810 00:29:39,950 --> 00:29:41,170 That's lapel David. 811 00:29:41,630 --> 00:29:42,130 And, 812 00:29:42,990 --> 00:29:45,630 so I created all these paintings, explored this 813 00:29:45,630 --> 00:29:48,190 idea and then presented them. And, oh my 814 00:29:48,190 --> 00:29:50,775 gosh. I had the best conversations with strangers 815 00:29:51,335 --> 00:29:53,734 because people would say, I know exactly what 816 00:29:53,734 --> 00:29:55,654 you mean. It's like when I'm driving really 817 00:29:55,654 --> 00:29:57,335 fast on the motorway and I have a 818 00:29:57,335 --> 00:29:58,934 little voice in my head, that's like, well, 819 00:29:58,934 --> 00:30:00,455 what would happen if, or, 820 00:30:03,750 --> 00:30:04,710 there was some very, 821 00:30:05,029 --> 00:30:07,190 interesting examples that other people gave me. Actually, 822 00:30:07,190 --> 00:30:08,950 maybe I won't share them because maybe that's 823 00:30:08,950 --> 00:30:10,490 a breaking of trust, but, 824 00:30:12,549 --> 00:30:14,710 it's a privilege as an artist that you 825 00:30:14,710 --> 00:30:15,769 get to be 826 00:30:16,789 --> 00:30:18,089 exploring these ideas, 827 00:30:18,554 --> 00:30:19,054 creating 828 00:30:19,355 --> 00:30:22,154 images, and then having the most amazing conversations 829 00:30:22,154 --> 00:30:24,075 with other people as those other people find 830 00:30:24,075 --> 00:30:25,934 value in the images that you've created. 831 00:30:26,554 --> 00:30:28,095 It's it's a complete privilege. 832 00:30:29,994 --> 00:30:32,554 Yeah. I tell you what's really lovely about 833 00:30:32,554 --> 00:30:33,294 the demon 834 00:30:33,809 --> 00:30:35,809 illustration that you did for us is when 835 00:30:35,809 --> 00:30:38,049 people come and stay with us or come 836 00:30:38,049 --> 00:30:39,889 and visit us, and they look at the 837 00:30:39,889 --> 00:30:41,569 picture and then they go Uh-huh. Hang on 838 00:30:41,569 --> 00:30:44,769 a second. Yeah. Is this is this and 839 00:30:44,769 --> 00:30:46,674 you're like, oh, yeah. Now I've got a 840 00:30:46,674 --> 00:30:49,555 proper friend because they recognize what this is. 841 00:30:49,555 --> 00:30:51,474 I I I love that too. I love, 842 00:30:52,115 --> 00:30:53,474 so as I said, I think mine is 843 00:30:53,474 --> 00:30:54,055 a cormorant. 844 00:30:55,315 --> 00:30:57,154 What is absolutely certain is that it's a 845 00:30:57,154 --> 00:30:59,710 bird because whenever I've sort of mentioned it, 846 00:31:00,090 --> 00:31:02,170 the concept of demons from historic materials to 847 00:31:02,170 --> 00:31:04,490 anyone, they've always gone, oh, you're a bird 848 00:31:04,490 --> 00:31:05,869 of some kind. Mhmm. 849 00:31:07,690 --> 00:31:09,529 And then it's just different people. Some people 850 00:31:09,769 --> 00:31:11,210 my I think my mother thinks I'm a 851 00:31:11,210 --> 00:31:11,710 jackdaw. 852 00:31:13,195 --> 00:31:13,695 Okay. 853 00:31:16,555 --> 00:31:18,315 They're very clever. I didn't know that's about 854 00:31:18,315 --> 00:31:19,994 me. They I think I think it means 855 00:31:19,994 --> 00:31:21,994 they're very clever, very useful. You use the 856 00:31:21,994 --> 00:31:24,634 tools to make the world a better place, 857 00:31:24,634 --> 00:31:26,095 so that seems fine. 858 00:31:26,750 --> 00:31:28,130 I like that interpretation. 859 00:31:29,710 --> 00:31:31,070 If people want to know, 860 00:31:31,549 --> 00:31:33,390 more about your work, where would they find 861 00:31:33,390 --> 00:31:35,250 you? Thank you so much for asking. 862 00:31:35,950 --> 00:31:36,930 I'm on Instagram. 863 00:31:37,950 --> 00:31:39,009 I have a website. 864 00:31:40,095 --> 00:31:42,994 Basically, if you search for Felicity ink pen, 865 00:31:43,134 --> 00:31:45,615 it is an unusual name. You're gonna find 866 00:31:45,615 --> 00:31:47,394 me. So you can just 867 00:31:47,695 --> 00:31:49,934 chuck my name into your search engine of 868 00:31:49,934 --> 00:31:50,434 choice, 869 00:31:50,894 --> 00:31:52,414 and you'll be able to find me on 870 00:31:52,414 --> 00:31:54,434 those. I'm also on Blue Sky and Substack 871 00:31:54,654 --> 00:31:57,509 at felicity ink pen. I highly recommend that 872 00:31:57,509 --> 00:32:00,490 you do find your way to looking through 873 00:32:00,789 --> 00:32:04,009 Felicity's work on those various links. But 874 00:32:04,390 --> 00:32:05,369 to dive deeper 875 00:32:05,750 --> 00:32:08,869 into the quantum briefing, here's someone whose voice 876 00:32:08,869 --> 00:32:11,224 and name might well be familiar 877 00:32:11,525 --> 00:32:13,525 to quite a few of you. Hi, Andrew. 878 00:32:13,525 --> 00:32:16,244 I'm Tishna Kumar Sarayat. I am the features 879 00:32:16,244 --> 00:32:17,785 editor for Physics World. 880 00:32:18,164 --> 00:32:20,805 And this year, my special project all year 881 00:32:20,805 --> 00:32:21,705 long is 882 00:32:22,200 --> 00:32:24,599 all our coverage for the international year of 883 00:32:24,599 --> 00:32:25,099 quantum 884 00:32:25,720 --> 00:32:28,599 technology and science twenty twenty five. So it's 885 00:32:28,599 --> 00:32:31,159 all quantum all the time for me. Yeah. 886 00:32:31,159 --> 00:32:32,700 Does that make you feel a bit weird? 887 00:32:34,119 --> 00:32:35,559 I like that part. No. Do you know 888 00:32:35,559 --> 00:32:36,539 what? My my 889 00:32:36,845 --> 00:32:38,605 aim for this year is to make most 890 00:32:38,605 --> 00:32:40,865 people think that quantum is not that weird. 891 00:32:41,005 --> 00:32:42,845 Or if it's weird, it's a fun kind 892 00:32:42,845 --> 00:32:44,924 of weird and not, oh, no idea what's 893 00:32:44,924 --> 00:32:46,305 going on kind of weird. 894 00:32:47,085 --> 00:32:49,404 Okay. But does because I find when I'm 895 00:32:49,404 --> 00:32:51,644 doing these podcasts about quantum that it makes 896 00:32:51,644 --> 00:32:54,039 me it makes me kind of think about 897 00:32:54,099 --> 00:32:55,619 what's going on around me in a slightly 898 00:32:55,619 --> 00:32:56,980 different way. If you're doing it all the 899 00:32:56,980 --> 00:32:58,339 time, does it not do that a little 900 00:32:58,339 --> 00:32:58,839 bit? 901 00:32:59,539 --> 00:33:01,380 It does. It does. It makes you have 902 00:33:01,380 --> 00:33:02,279 this amazing 903 00:33:02,900 --> 00:33:03,400 appreciation 904 00:33:03,859 --> 00:33:04,680 for how 905 00:33:05,325 --> 00:33:06,544 strange and wonderful, 906 00:33:07,085 --> 00:33:08,924 the world is around us and and the 907 00:33:08,924 --> 00:33:10,605 fact that there's still so much to be 908 00:33:10,605 --> 00:33:12,284 learned. There's so much that we don't understand 909 00:33:12,284 --> 00:33:16,065 about what is essentially a really fundamental aspect 910 00:33:16,125 --> 00:33:17,265 of our existence. 911 00:33:19,170 --> 00:33:21,170 So you have a quantum briefing. We we 912 00:33:21,170 --> 00:33:23,329 were we were developing this briefing in the 913 00:33:23,329 --> 00:33:24,710 early half of the year, 914 00:33:25,089 --> 00:33:27,089 and, you know, we were saying, well, we've 915 00:33:27,089 --> 00:33:29,170 got so much excellent content in it. We 916 00:33:29,170 --> 00:33:31,670 want something really exciting on the cover. 917 00:33:32,494 --> 00:33:35,454 And here's the thing. Right? Quantum mechanics, very 918 00:33:35,454 --> 00:33:36,434 popular subject, 919 00:33:37,054 --> 00:33:39,454 very hard to have interesting pretty pictures of 920 00:33:39,454 --> 00:33:41,294 it because it's not something you can photograph. 921 00:33:41,294 --> 00:33:42,894 You know? It's not like astronomy. You can't 922 00:33:42,894 --> 00:33:44,494 stick a pretty picture of a galaxy or 923 00:33:44,494 --> 00:33:47,419 a nebula on. It's really hard to visualize. 924 00:33:48,440 --> 00:33:50,759 And I realized that all the magazines and 925 00:33:50,759 --> 00:33:53,640 things that are out right now, everyone's using 926 00:33:53,640 --> 00:33:56,679 the same 40 or 50 pictures from, you 927 00:33:56,679 --> 00:33:59,160 know, Shutterstock and iStock and Science Photos. So 928 00:33:59,160 --> 00:34:01,285 it's either a picture of a so called 929 00:34:01,285 --> 00:34:04,105 quantum computer, which is mostly the dilution refrigeration 930 00:34:04,404 --> 00:34:06,725 part of it because the actual computer is 931 00:34:06,725 --> 00:34:08,345 really tiny and boring looking, 932 00:34:09,605 --> 00:34:11,204 or it's something, you know, some sort of 933 00:34:11,204 --> 00:34:14,344 bushy lines that look vaguely like an atom 934 00:34:14,769 --> 00:34:16,769 or something like that. And I wanted something 935 00:34:16,769 --> 00:34:19,750 really different and visually exciting on the cover. 936 00:34:20,369 --> 00:34:22,530 And so I thought I wanted an artist 937 00:34:22,530 --> 00:34:25,190 who really understands quantum mechanics to represent, 938 00:34:26,450 --> 00:34:29,425 their idea of key quantum concepts on the 939 00:34:29,425 --> 00:34:32,244 cover. And so I thought of, Felicity, Fliss, 940 00:34:32,625 --> 00:34:34,784 who used to work at IOP publishing many 941 00:34:34,784 --> 00:34:36,724 years ago, and she has a big background 942 00:34:37,025 --> 00:34:37,844 in science. 943 00:34:38,144 --> 00:34:39,425 And so I sort of reached out to 944 00:34:39,425 --> 00:34:40,784 her and I said, hey. Would you like 945 00:34:40,784 --> 00:34:42,784 to paint something about quantum? And she absolutely 946 00:34:42,784 --> 00:34:43,050 loved it, 947 00:34:45,610 --> 00:34:48,170 and so, you know, I'm sure you've heard 948 00:34:48,170 --> 00:34:49,530 her talk about how she came up with 949 00:34:49,530 --> 00:34:52,349 the the dyes and the imaging and then 950 00:34:52,730 --> 00:34:56,010 her stunning painting, cubit's duality, which I love, 951 00:34:56,010 --> 00:34:57,769 which I think is just amazing on the 952 00:34:57,769 --> 00:34:58,269 cover. 953 00:34:58,635 --> 00:35:00,815 I think it really gives you this 954 00:35:01,114 --> 00:35:02,414 amazing sense of 955 00:35:02,954 --> 00:35:05,295 the ideas of entanglement and superposition, 956 00:35:05,594 --> 00:35:07,755 but in a beautiful way that is quite 957 00:35:07,755 --> 00:35:08,655 rare to 958 00:35:09,034 --> 00:35:11,900 associate with quantum mechanics. So yeah. 959 00:35:12,519 --> 00:35:14,119 It's quite a lovely thing, isn't it? Because 960 00:35:14,119 --> 00:35:15,559 I've done some things in the past where 961 00:35:15,559 --> 00:35:17,880 you've been kinda working on something, and then 962 00:35:17,880 --> 00:35:19,799 as a result of what you're working on, 963 00:35:19,799 --> 00:35:21,559 something else has come out of it. Some 964 00:35:21,559 --> 00:35:23,559 sort of art or creation or something's come 965 00:35:23,559 --> 00:35:25,155 out of it. It's just a lovely thing 966 00:35:25,155 --> 00:35:27,474 to happen, isn't it? Absolutely. And I'm so 967 00:35:27,474 --> 00:35:30,515 happy to say that this painting is being 968 00:35:30,515 --> 00:35:33,494 displayed all over The UK at different events. 969 00:35:34,114 --> 00:35:36,835 So two weeks ago, it was displayed as 970 00:35:36,835 --> 00:35:39,795 part of the Great Exhibition Road Festival in 971 00:35:39,795 --> 00:35:40,295 London, 972 00:35:40,659 --> 00:35:42,599 and it was part of Imperial's, 973 00:35:43,219 --> 00:35:44,099 quantum art, 974 00:35:44,659 --> 00:35:47,559 quantum jungle where they had all these amazing, 975 00:35:48,500 --> 00:35:50,840 pieces of quantum art, some of them interactive. 976 00:35:51,380 --> 00:35:53,139 And there were so many people there, so 977 00:35:53,139 --> 00:35:55,664 many young children. It was amazing having them 978 00:35:55,664 --> 00:35:57,765 all look at this and go, oh, pretty, 979 00:35:57,824 --> 00:36:00,005 you know, which is quite rare for quantum. 980 00:36:01,265 --> 00:36:03,105 Hopefully, the painting is going to also be 981 00:36:03,105 --> 00:36:04,545 displayed at the, 982 00:36:05,425 --> 00:36:05,925 Royal 983 00:36:06,224 --> 00:36:08,785 Society Summer Festival. And later on in the 984 00:36:08,785 --> 00:36:11,410 year, the Science Gallery in London is having 985 00:36:11,410 --> 00:36:13,809 a special quantum exhibition, and, 986 00:36:14,690 --> 00:36:17,170 Qubit's Duality will be seen there too. So 987 00:36:17,170 --> 00:36:19,410 if you're anywhere in The UK, keep your 988 00:36:19,410 --> 00:36:21,974 eyes peeled for our stunning quantum art. 989 00:36:22,695 --> 00:36:25,255 Amazing. Yeah. I've I didn't know that. That's 990 00:36:25,255 --> 00:36:27,335 a delightful thing. I'll be finding my way 991 00:36:27,335 --> 00:36:28,934 to one of those. Because the other place 992 00:36:28,934 --> 00:36:30,614 I can see is on the front cover 993 00:36:30,614 --> 00:36:32,855 of the Quantum Briefing, and I would like 994 00:36:32,855 --> 00:36:35,434 to just sort of open the pages 995 00:36:36,829 --> 00:36:39,710 of that and look inside. What's sort of 996 00:36:39,710 --> 00:36:41,869 drawn you as you've been looking into it 997 00:36:41,869 --> 00:36:44,750 and, putting this this briefing together? You know, 998 00:36:44,750 --> 00:36:46,909 sometimes you you come up with what you 999 00:36:46,909 --> 00:36:47,409 want 1000 00:36:47,710 --> 00:36:50,030 to go exactly, what you wanna cover in 1001 00:36:50,030 --> 00:36:51,170 this kind of thing, 1002 00:36:51,775 --> 00:36:52,994 in the special collection. 1003 00:36:53,375 --> 00:36:55,135 And other times, you sort of look at 1004 00:36:55,215 --> 00:36:58,094 we we have so much exciting quantum content 1005 00:36:58,094 --> 00:36:59,235 that we pull together, 1006 00:37:00,094 --> 00:37:02,574 this massive spreadsheet, and then we actually had 1007 00:37:02,574 --> 00:37:04,480 to cut things down. Because if we we 1008 00:37:04,480 --> 00:37:06,000 printed it all and put it all in, 1009 00:37:06,000 --> 00:37:07,680 it would have been 200 pages. It would 1010 00:37:07,680 --> 00:37:08,579 have been a book. 1011 00:37:09,360 --> 00:37:11,119 So we had to sort of choose the 1012 00:37:11,119 --> 00:37:12,559 best of the best of the best, the 1013 00:37:12,559 --> 00:37:15,380 most interesting things. And as we pulled, 1014 00:37:16,000 --> 00:37:18,579 content together, we realized that naturally, 1015 00:37:19,934 --> 00:37:23,155 all the content divided up into three sections 1016 00:37:23,295 --> 00:37:25,215 that with a little bit of whimsy, we 1017 00:37:25,215 --> 00:37:27,394 decided to call quantum history, 1018 00:37:27,934 --> 00:37:31,135 quantum mystery, and quantum industry. And then, of 1019 00:37:31,135 --> 00:37:32,760 course, there's a bit of science and culture 1020 00:37:32,920 --> 00:37:34,679 because we like science and culture, and we 1021 00:37:34,679 --> 00:37:36,300 think that's a key part of, 1022 00:37:37,079 --> 00:37:38,380 the scientific process. 1023 00:37:39,000 --> 00:37:41,500 So that that's sort of the sections, 1024 00:37:42,039 --> 00:37:43,820 that it covers. Obviously, history 1025 00:37:44,280 --> 00:37:45,525 looks back at, 1026 00:37:46,484 --> 00:37:47,864 some key people, 1027 00:37:48,724 --> 00:37:51,525 who were pivotal in the discovery of quantum 1028 00:37:51,525 --> 00:37:52,025 mechanics. 1029 00:37:52,804 --> 00:37:55,364 Quite a fun feature that starts out on 1030 00:37:55,364 --> 00:37:57,625 the island of Helgoland, which is sort of 1031 00:37:57,844 --> 00:38:00,244 where it all began a hundred years ago, 1032 00:38:01,500 --> 00:38:02,960 the island on which Heisenberg 1033 00:38:03,500 --> 00:38:05,679 sort of went to recover from his blistering 1034 00:38:05,739 --> 00:38:06,960 hay fever and 1035 00:38:07,340 --> 00:38:09,519 sort of wrote down the mathematical 1036 00:38:09,820 --> 00:38:12,320 matrix equations of of quantum mechanics. 1037 00:38:13,579 --> 00:38:16,385 What's really fun is that Helgoland was 1038 00:38:17,085 --> 00:38:18,144 the site for, 1039 00:38:18,765 --> 00:38:20,545 the hundred year anniversary conference, 1040 00:38:21,485 --> 00:38:22,864 the Helgoland conference. 1041 00:38:23,804 --> 00:38:26,364 A week ago, and Nitin Drani, who is 1042 00:38:26,364 --> 00:38:26,864 editor, 1043 00:38:27,324 --> 00:38:30,000 of Physics World, editor in chief, He managed 1044 00:38:30,000 --> 00:38:31,699 to go along to this conference, 1045 00:38:32,320 --> 00:38:34,019 and, I would definitely 1046 00:38:34,320 --> 00:38:37,199 recommend reading his blogs on sort of all 1047 00:38:37,199 --> 00:38:39,380 the things that they discussed that look back 1048 00:38:39,519 --> 00:38:41,940 at a hundred years of quantum mechanics and 1049 00:38:42,000 --> 00:38:44,385 look forward at the next one hundred years. 1050 00:38:44,385 --> 00:38:46,385 Is that was that a big argument in 1051 00:38:46,385 --> 00:38:48,545 the physics world office as who was going 1052 00:38:48,545 --> 00:38:49,844 to get to go to that one? 1053 00:38:51,025 --> 00:38:52,945 Well, it's funny you say that, but do 1054 00:38:52,945 --> 00:38:55,425 you know what? This this island is really 1055 00:38:55,425 --> 00:38:57,664 a tiny island off the coast of Germany. 1056 00:38:57,664 --> 00:38:58,889 It's really not built 1057 00:38:59,369 --> 00:39:01,309 for, you know, a huge amount of physicists 1058 00:39:01,369 --> 00:39:04,329 to land up. And so very quickly, what 1059 00:39:04,329 --> 00:39:06,809 happened with the Helgoland conference was that every 1060 00:39:06,809 --> 00:39:09,049 possible location where you could stay on the 1061 00:39:09,049 --> 00:39:09,549 island 1062 00:39:09,929 --> 00:39:11,929 sold out. So they were asking people to 1063 00:39:11,929 --> 00:39:14,170 pair up and share rooms. And the final 1064 00:39:14,170 --> 00:39:14,670 option, 1065 00:39:15,105 --> 00:39:17,664 which I heard a couple of people did 1066 00:39:17,664 --> 00:39:20,405 succumb to, was to camp on the island. 1067 00:39:21,344 --> 00:39:24,545 And from Mateen's reporting, it was fairly cold 1068 00:39:24,545 --> 00:39:26,565 and windy, so not exactly 1069 00:39:27,505 --> 00:39:28,324 the dream, 1070 00:39:28,864 --> 00:39:30,480 holiday or anything. But 1071 00:39:30,960 --> 00:39:32,960 as Mazin says in his final blog, he 1072 00:39:32,960 --> 00:39:35,539 felt that he could really understand why Helgoland 1073 00:39:35,679 --> 00:39:37,380 was such a good place for thinking 1074 00:39:37,920 --> 00:39:41,119 and coming up with amazing new ideas. So 1075 00:39:41,119 --> 00:39:41,699 if you're 1076 00:39:42,000 --> 00:39:44,019 if you're looking for a place for inspiration 1077 00:39:44,320 --> 00:39:46,260 and some bracing sea air, 1078 00:39:46,775 --> 00:39:49,094 perhaps Helgoland should be on your list now 1079 00:39:49,094 --> 00:39:51,494 that all the quantum physicists have on hand. 1080 00:39:51,494 --> 00:39:53,494 I've I've I've got maybe I'll take get 1081 00:39:53,494 --> 00:39:55,255 that painting somehow and take it with me. 1082 00:39:55,255 --> 00:39:56,215 I'll tell you what. I'll just take the 1083 00:39:56,215 --> 00:39:58,155 briefing. It's on the front cover of that. 1084 00:39:58,295 --> 00:39:59,894 Oh, well, there you go. So There you 1085 00:39:59,894 --> 00:40:01,575 go. Back at the history of it, if 1086 00:40:01,575 --> 00:40:03,069 we can do that first of all, 1087 00:40:04,030 --> 00:40:06,510 the other people in this story I asked 1088 00:40:06,510 --> 00:40:08,670 that question knowing the answer to it. But 1089 00:40:08,670 --> 00:40:10,349 other people in the history of the story 1090 00:40:10,349 --> 00:40:12,589 whose story hasn't been told and maybe should 1091 00:40:12,589 --> 00:40:13,250 have been? 1092 00:40:14,429 --> 00:40:15,409 Yes. Absolutely. 1093 00:40:16,190 --> 00:40:18,905 You know, obviously, everyone everyone knows of Heisenberg. 1094 00:40:19,204 --> 00:40:20,265 Everyone knows of 1095 00:40:20,724 --> 00:40:22,405 of Niels Bohr. By the way, there's a 1096 00:40:22,405 --> 00:40:24,485 great feature about Niels Bohr and something that 1097 00:40:24,485 --> 00:40:26,405 he got really wrong, which I really enjoy. 1098 00:40:26,405 --> 00:40:28,585 I really like it. Very clever people 1099 00:40:28,965 --> 00:40:30,824 come up with what they think were fantastic 1100 00:40:30,885 --> 00:40:33,119 ideas and then are very quickly proven wrong 1101 00:40:33,200 --> 00:40:35,200 because it's always amazing to me how happy 1102 00:40:35,200 --> 00:40:37,039 they are about that. They're always like, oh, 1103 00:40:37,039 --> 00:40:38,099 well, try that, 1104 00:40:38,559 --> 00:40:41,119 but this is more exciting that I'm wrong. 1105 00:40:41,119 --> 00:40:43,440 And so there's a great feature called when 1106 00:40:43,440 --> 00:40:44,500 Bohr got it wrong. 1107 00:40:45,680 --> 00:40:47,440 And I'll I'll leave you to read that 1108 00:40:47,440 --> 00:40:49,135 to find out what exactly it was that 1109 00:40:49,135 --> 00:40:51,295 he proposed in the very early days of 1110 00:40:51,295 --> 00:40:54,494 quantum mechanics that was quickly proven wrong. But 1111 00:40:54,494 --> 00:40:56,574 the person you referred to, the sort of 1112 00:40:56,574 --> 00:40:57,554 missing person, 1113 00:40:58,494 --> 00:41:01,315 was this amazing German physicist and philosopher 1114 00:41:01,614 --> 00:41:03,315 by the name of Greta Hermann. 1115 00:41:03,890 --> 00:41:06,610 Now she was someone who was a true 1116 00:41:06,610 --> 00:41:07,110 contemporary 1117 00:41:07,489 --> 00:41:08,550 of of Heisenberg 1118 00:41:09,090 --> 00:41:10,949 and even John von Neumann. 1119 00:41:11,410 --> 00:41:14,369 And so she was sort of very active 1120 00:41:14,369 --> 00:41:16,390 in those early days. And she 1121 00:41:16,835 --> 00:41:19,154 because she was a philosopher and not just 1122 00:41:19,154 --> 00:41:19,894 a physicist, 1123 00:41:20,355 --> 00:41:23,174 she had some very certain interesting ideas 1124 00:41:23,795 --> 00:41:24,295 about 1125 00:41:24,674 --> 00:41:25,654 quantum fundamentals 1126 00:41:26,514 --> 00:41:28,375 at a time when they were really discussing, 1127 00:41:28,434 --> 00:41:30,880 you know, whether you you were in Boer's 1128 00:41:31,099 --> 00:41:33,360 camp or or Einstein's camp, etcetera. 1129 00:41:34,539 --> 00:41:36,460 And she sort of proposed some of the 1130 00:41:36,460 --> 00:41:38,400 things that we later attribute 1131 00:41:39,340 --> 00:41:39,840 completely 1132 00:41:40,539 --> 00:41:42,885 to von Neumann was actually things that 1133 00:41:43,844 --> 00:41:46,724 she had suggested or talked about or even 1134 00:41:46,724 --> 00:41:49,764 proved much earlier than he had. But, you 1135 00:41:49,764 --> 00:41:52,324 know, because she was a very, highly trained 1136 00:41:52,324 --> 00:41:52,824 mathematician. 1137 00:41:53,204 --> 00:41:54,264 So she actually 1138 00:41:54,804 --> 00:41:57,239 used her skills and training to point out 1139 00:41:57,239 --> 00:41:59,420 some early flaws in von Neumann's 1140 00:41:59,960 --> 00:42:02,360 early proofs that there were these no hidden 1141 00:42:02,360 --> 00:42:03,579 variable theories, 1142 00:42:03,960 --> 00:42:05,639 etcetera. And so she came up with some 1143 00:42:05,639 --> 00:42:07,960 great responses to that, but no one you 1144 00:42:07,960 --> 00:42:09,719 know, she sparred with von Neumann, but no 1145 00:42:09,719 --> 00:42:11,659 one really knows about her today. 1146 00:42:13,738 --> 00:42:15,204 After the the war, she sort of went 1147 00:42:15,204 --> 00:42:17,445 off and did some quite different things because 1148 00:42:17,445 --> 00:42:19,945 she was interested. She was a free thinker. 1149 00:42:20,005 --> 00:42:21,785 She was, you know, working with the unions 1150 00:42:21,844 --> 00:42:23,144 and things like that. 1151 00:42:23,525 --> 00:42:26,005 But she had these really great ideas about 1152 00:42:26,005 --> 00:42:26,505 quantum 1153 00:42:27,150 --> 00:42:27,650 causality, 1154 00:42:28,510 --> 00:42:30,510 and things like that. And so her legacy 1155 00:42:30,510 --> 00:42:32,609 is something that we really wanted to highlight 1156 00:42:32,909 --> 00:42:34,049 in our history. 1157 00:42:34,349 --> 00:42:36,289 Can I ask you a very silly question? 1158 00:42:36,510 --> 00:42:38,589 Why is she not more well known? Why 1159 00:42:38,589 --> 00:42:39,069 was the 1160 00:42:39,710 --> 00:42:40,530 Oh, I mean, 1161 00:42:40,909 --> 00:42:41,730 oh, Andrew. 1162 00:42:42,585 --> 00:42:43,244 I feel 1163 00:42:44,264 --> 00:42:45,405 like I feel like, unfortunately, 1164 00:42:45,784 --> 00:42:47,784 there is this you know, it's it's almost 1165 00:42:47,784 --> 00:42:49,704 a term that we now know called hidden 1166 00:42:49,704 --> 00:42:52,125 figures, and and you almost consistently, 1167 00:42:52,505 --> 00:42:53,244 those figures 1168 00:42:53,625 --> 00:42:54,284 are women 1169 00:42:54,585 --> 00:42:57,324 or or people from other minority backgrounds 1170 00:42:57,840 --> 00:43:00,420 who sort of played such key roles 1171 00:43:01,119 --> 00:43:02,579 in so much of 1172 00:43:03,280 --> 00:43:04,099 the fundamental 1173 00:43:04,400 --> 00:43:07,280 development of science over eons, and they just 1174 00:43:07,280 --> 00:43:09,440 got written out because they were the wrong 1175 00:43:09,440 --> 00:43:12,244 kind of people to be in those stories 1176 00:43:12,304 --> 00:43:14,864 and or they just didn't shout loud enough 1177 00:43:14,864 --> 00:43:17,105 or they just didn't have a platform for 1178 00:43:17,105 --> 00:43:18,085 it. And, unfortunately, 1179 00:43:19,025 --> 00:43:21,585 you know, it's sort of it's almost sort 1180 00:43:21,585 --> 00:43:23,744 of happening again now while we haven't even 1181 00:43:23,744 --> 00:43:25,505 got all of those hidden figures out and 1182 00:43:25,505 --> 00:43:27,059 and women are being written out of the 1183 00:43:27,059 --> 00:43:27,960 story again, 1184 00:43:28,980 --> 00:43:29,480 unfortunately, 1185 00:43:30,180 --> 00:43:31,880 in The US right now. But 1186 00:43:32,900 --> 00:43:35,300 so, yeah, I mean, it's quite sad that 1187 00:43:35,300 --> 00:43:36,039 we're still 1188 00:43:36,420 --> 00:43:38,119 finding these amazing people. 1189 00:43:38,500 --> 00:43:41,000 But, hopefully, all these stories will be told 1190 00:43:41,364 --> 00:43:42,184 and appreciated. 1191 00:43:43,125 --> 00:43:43,625 Yes. 1192 00:43:44,885 --> 00:43:45,385 Absolutely. 1193 00:43:46,244 --> 00:43:48,244 I can't quite believe it's happening again. But, 1194 00:43:48,405 --> 00:43:49,305 that's the history. 1195 00:43:49,684 --> 00:43:51,765 Can we turn now to the mystery, not 1196 00:43:51,765 --> 00:43:53,605 just the mystery of why the the people 1197 00:43:53,605 --> 00:43:55,864 I've talked about more who were so instrumental 1198 00:43:56,210 --> 00:43:58,049 in it, but the mystery of the science. 1199 00:43:58,049 --> 00:43:59,190 Absolutely. Yeah. 1200 00:43:59,889 --> 00:44:01,730 So quite often, when we talk about quantum 1201 00:44:01,730 --> 00:44:04,869 mechanics, people refer to things like 1202 00:44:05,329 --> 00:44:06,789 quantum and, you know, entanglement, 1203 00:44:07,569 --> 00:44:10,275 this idea that you you can have quantum 1204 00:44:10,275 --> 00:44:13,414 particles that are inherently linked to one another 1205 00:44:13,795 --> 00:44:15,894 even if they're nowhere in the same 1206 00:44:16,514 --> 00:44:18,275 space and, you know, this can be across 1207 00:44:18,275 --> 00:44:18,934 the universe, 1208 00:44:19,714 --> 00:44:20,855 or or superposition 1209 00:44:21,234 --> 00:44:23,315 where different quantum states are all at the 1210 00:44:23,315 --> 00:44:25,414 same sort of happening at the same time. 1211 00:44:26,400 --> 00:44:28,239 And these are these quantum effects that are 1212 00:44:28,239 --> 00:44:30,179 deemed so weird and strange, 1213 00:44:30,559 --> 00:44:31,300 but, actually, 1214 00:44:31,839 --> 00:44:34,079 there are a number those concepts have been 1215 00:44:34,079 --> 00:44:36,000 around now for a hundred years, and they're 1216 00:44:36,000 --> 00:44:37,760 pretty well understood. We test them in the 1217 00:44:37,760 --> 00:44:39,839 lab. We do experiments with them. We use 1218 00:44:39,839 --> 00:44:40,900 them all the time. 1219 00:44:41,484 --> 00:44:43,964 But there's these other quantum effects that have 1220 00:44:43,964 --> 00:44:46,364 maybe been discovered a bit later that are 1221 00:44:46,364 --> 00:44:48,525 even stranger. They're even weirder. And the way 1222 00:44:48,525 --> 00:44:50,684 we see it is that they're so odd 1223 00:44:50,684 --> 00:44:54,125 that they make superposition and entanglement seem almost 1224 00:44:54,125 --> 00:44:54,625 ordinary. 1225 00:44:55,280 --> 00:44:57,119 So that's what we kind of wanted to 1226 00:44:57,119 --> 00:44:58,579 highlight through this, 1227 00:44:58,960 --> 00:45:00,339 International Year of Quantum. 1228 00:45:00,800 --> 00:45:02,719 And we've got the first three of these 1229 00:45:02,719 --> 00:45:03,219 effects, 1230 00:45:04,239 --> 00:45:06,480 in the guide. The first one is the 1231 00:45:06,480 --> 00:45:06,980 quantum 1232 00:45:07,280 --> 00:45:08,260 Zeno effect. 1233 00:45:08,880 --> 00:45:11,154 Then we have quantum Cheshire cats, and then 1234 00:45:11,154 --> 00:45:14,594 we have the quantum eraser delayed choice effect, 1235 00:45:14,594 --> 00:45:15,494 which are all 1236 00:45:15,795 --> 00:45:16,934 pretty mysterious. 1237 00:45:17,234 --> 00:45:19,234 Yeah. Yes. They are. But but to a 1238 00:45:19,234 --> 00:45:21,315 certain extent, I wonder if some of these 1239 00:45:21,315 --> 00:45:23,154 things do require a bit of time with 1240 00:45:23,154 --> 00:45:26,050 reading in order to, you know, really grasp 1241 00:45:26,050 --> 00:45:28,849 them Yes. Rather than just hearing about them 1242 00:45:28,849 --> 00:45:31,489 on a podcast, I think. Yeah. I think 1243 00:45:31,489 --> 00:45:33,969 these are what we kind of what we 1244 00:45:33,969 --> 00:45:36,210 think of as lean forward articles. You have 1245 00:45:36,210 --> 00:45:38,230 to pay a little bit of attention and 1246 00:45:38,505 --> 00:45:40,984 stay with us to learn something truly mind 1247 00:45:40,984 --> 00:45:41,484 boggling. 1248 00:45:41,944 --> 00:45:43,944 Okay. So I'm gonna pick one of them. 1249 00:45:44,184 --> 00:45:45,304 And you could just shout at me if 1250 00:45:45,304 --> 00:45:46,505 it's the wrong one to pick, but I'll 1251 00:45:46,505 --> 00:45:47,724 just pick one of them. 1252 00:45:48,184 --> 00:45:50,025 And I'm gonna pick this one, but largely 1253 00:45:50,025 --> 00:45:51,484 because I was born in Cheshire. 1254 00:45:51,944 --> 00:45:53,565 The Quantum Cheshire Cat. 1255 00:45:54,599 --> 00:45:56,300 Absolutely. One of my favorites. 1256 00:45:56,760 --> 00:45:58,519 And it also happens to me the same 1257 00:45:58,519 --> 00:46:01,400 feature is also in the Jude issue of 1258 00:46:01,400 --> 00:46:03,720 Physics World, and it's on the cover. So 1259 00:46:03,720 --> 00:46:05,320 you have all these lovely cats on the 1260 00:46:05,320 --> 00:46:07,019 cover. It's a very exciting cover. 1261 00:46:07,525 --> 00:46:09,364 Just a quick aside here because there are 1262 00:46:09,364 --> 00:46:10,664 some wonderful illustrations, 1263 00:46:10,965 --> 00:46:13,204 not only on the front cover of Physics 1264 00:46:13,204 --> 00:46:15,284 World magazine, but in the quantum briefing to 1265 00:46:15,284 --> 00:46:16,105 go alongside 1266 00:46:16,804 --> 00:46:17,945 some of these wonderful 1267 00:46:18,485 --> 00:46:20,750 stories of quantum physics. So I do recommend 1268 00:46:20,750 --> 00:46:22,909 if you're interested in that kind of cross 1269 00:46:22,909 --> 00:46:24,909 section between science and art we've been talking 1270 00:46:24,909 --> 00:46:28,050 about to delve into both the magazine 1271 00:46:28,429 --> 00:46:29,730 and the Quantum Briefing. 1272 00:46:30,030 --> 00:46:31,090 Back to Tushnet. 1273 00:46:32,184 --> 00:46:36,105 Quantum Cheshire cats. Truly, truly mind boggling stuff. 1274 00:46:36,105 --> 00:46:36,605 So 1275 00:46:36,905 --> 00:46:38,585 for those of you who've read Alice in 1276 00:46:38,585 --> 00:46:41,324 Wonderland, you'll be familiar with the Cheshire cat, 1277 00:46:41,784 --> 00:46:44,025 that has does this amazing thing where it 1278 00:46:44,025 --> 00:46:47,005 slowly disappears, leaving behind its grin. 1279 00:46:47,390 --> 00:46:49,230 The grin is the last thing that disappears, 1280 00:46:49,230 --> 00:46:51,309 and Alice sort of says that I've often 1281 00:46:51,309 --> 00:46:53,309 seen a cat without a grin, but a 1282 00:46:53,309 --> 00:46:55,230 grin without a cat, that is the most 1283 00:46:55,230 --> 00:46:57,170 curious thing I ever saw in my life. 1284 00:46:58,510 --> 00:46:59,730 And so I'm 1285 00:47:00,945 --> 00:47:02,625 in in the eighties, there were a bunch 1286 00:47:02,625 --> 00:47:05,285 of physicists who who perhaps thought very deeply 1287 00:47:05,345 --> 00:47:06,885 about grinning cats. 1288 00:47:08,465 --> 00:47:11,765 And so they put forward this really crazy 1289 00:47:12,860 --> 00:47:13,360 proposition 1290 00:47:13,900 --> 00:47:15,980 in the early nineteen eighties. This was, 1291 00:47:16,380 --> 00:47:17,440 Yakir Aronov, 1292 00:47:18,380 --> 00:47:19,280 Sandu Provasku, 1293 00:47:19,820 --> 00:47:20,300 and, 1294 00:47:21,579 --> 00:47:22,079 colleagues. 1295 00:47:22,380 --> 00:47:23,119 And they 1296 00:47:23,820 --> 00:47:26,005 came up with this suggestion that they said 1297 00:47:26,005 --> 00:47:28,585 that because of the way quantum properties 1298 00:47:28,885 --> 00:47:30,724 are of of a certain particle. So if 1299 00:47:30,724 --> 00:47:31,704 you look at 1300 00:47:32,164 --> 00:47:34,985 a particle such as a photon, now photons, 1301 00:47:35,125 --> 00:47:36,344 particles of light, 1302 00:47:37,139 --> 00:47:39,719 they have polarization. We all know what polarization 1303 00:47:40,099 --> 00:47:40,760 is. Right? 1304 00:47:41,219 --> 00:47:41,719 So 1305 00:47:42,819 --> 00:47:46,280 they found that you could have a quantum 1306 00:47:46,420 --> 00:47:47,639 particle, a photon's 1307 00:47:48,019 --> 00:47:48,519 polarization 1308 00:47:49,139 --> 00:47:52,039 in a completely different physical location 1309 00:47:52,835 --> 00:47:54,855 from the actual particle itself. 1310 00:47:55,635 --> 00:47:57,414 So like the Cheshire cat, 1311 00:47:57,795 --> 00:48:00,194 the grin is separate from the cat, and 1312 00:48:00,194 --> 00:48:01,974 so the photons' polarization 1313 00:48:02,755 --> 00:48:03,574 is actually 1314 00:48:03,875 --> 00:48:06,994 in a physically separate location from the photon 1315 00:48:06,994 --> 00:48:08,099 itself. What? 1316 00:48:09,059 --> 00:48:10,680 Yeah. I know. I know. 1317 00:48:11,460 --> 00:48:12,980 And the crazy thing is that they came 1318 00:48:12,980 --> 00:48:14,840 up with this almost like a sort of 1319 00:48:14,980 --> 00:48:15,880 thought experiment 1320 00:48:16,500 --> 00:48:17,619 in the early eighties. 1321 00:48:17,940 --> 00:48:19,780 This this it was an idea, a concept 1322 00:48:19,780 --> 00:48:22,054 that they said that, you know, if if 1323 00:48:22,054 --> 00:48:24,795 you make, a measurement on a quantum system, 1324 00:48:25,174 --> 00:48:27,255 it collapses the system. You know, it's when 1325 00:48:27,255 --> 00:48:28,474 you have a certain 1326 00:48:29,174 --> 00:48:29,674 entanglement 1327 00:48:29,974 --> 00:48:30,875 or a certain position. 1328 00:48:31,255 --> 00:48:32,855 You make a measurement. You sort of poke 1329 00:48:32,855 --> 00:48:35,109 the system, and it causes the system to 1330 00:48:35,109 --> 00:48:37,829 change immediately because quantum systems don't like being 1331 00:48:37,829 --> 00:48:38,329 watched. 1332 00:48:39,349 --> 00:48:40,710 And so you, you know, then you find 1333 00:48:40,710 --> 00:48:42,070 out it's like open the box and you 1334 00:48:42,070 --> 00:48:43,769 find out the cat is dead or alive. 1335 00:48:43,829 --> 00:48:45,130 I was Schrodinger. Right? 1336 00:48:45,590 --> 00:48:48,554 But there's this there's this amazing idea. So 1337 00:48:48,554 --> 00:48:50,574 so that's what you call a very definitive 1338 00:48:50,635 --> 00:48:53,275 measurement, but there's this phenomenal concept in quantum 1339 00:48:53,275 --> 00:48:54,894 mechanics called weak measurements. 1340 00:48:55,355 --> 00:48:58,574 So that's like not fully opening the box, 1341 00:48:58,795 --> 00:49:00,474 not opening it all the way and letting 1342 00:49:00,474 --> 00:49:02,074 all the, you know, light out to see 1343 00:49:02,074 --> 00:49:03,890 if there's definitely a dead cat. But what 1344 00:49:03,890 --> 00:49:06,130 if you did something like just a teeny 1345 00:49:06,130 --> 00:49:08,289 tiny little peak, sort of look from the 1346 00:49:08,289 --> 00:49:10,309 corner of your eye without really looking? 1347 00:49:10,690 --> 00:49:11,190 So 1348 00:49:11,490 --> 00:49:14,450 that's what physicists called weak measurements. So that's 1349 00:49:14,450 --> 00:49:16,769 where you do sort of a series of 1350 00:49:16,769 --> 00:49:19,025 very gentle pokes on a system, 1351 00:49:19,324 --> 00:49:21,484 and you keep measuring those. You you make 1352 00:49:21,484 --> 00:49:23,025 these tiny, tiny, tiny measurements, 1353 00:49:23,405 --> 00:49:25,244 and then you add up the sum of 1354 00:49:25,244 --> 00:49:28,385 this measurement to get a sort of coherent 1355 00:49:28,605 --> 00:49:31,744 answer by doing these tiny, tiny, gentle pokes. 1356 00:49:32,525 --> 00:49:33,025 So 1357 00:49:33,890 --> 00:49:35,969 this this concept of weak measurements was sort 1358 00:49:35,969 --> 00:49:38,610 of a radical idea in quantum mechanics when 1359 00:49:38,610 --> 00:49:41,329 it happened. And so so they realized that 1360 00:49:41,329 --> 00:49:43,349 if you set up you do a certain 1361 00:49:43,410 --> 00:49:43,910 series 1362 00:49:44,450 --> 00:49:46,150 of sort of what they call preselection 1363 00:49:46,530 --> 00:49:47,030 criteria 1364 00:49:47,434 --> 00:49:49,034 to set up a photon, and then you 1365 00:49:49,034 --> 00:49:50,414 put it through a beam splitter, 1366 00:49:51,034 --> 00:49:53,215 send it, you know, do do the standard 1367 00:49:53,275 --> 00:49:55,835 sort of interferometry that we do with photons, 1368 00:49:55,835 --> 00:49:57,994 you know, to check, then you get a 1369 00:49:57,994 --> 00:50:00,715 system where the photon ends up in one 1370 00:50:00,715 --> 00:50:02,974 arm of the beam splitter and the polarization 1371 00:50:03,420 --> 00:50:05,579 is in the other arm. And then you 1372 00:50:05,579 --> 00:50:07,579 can put the two bits back together and 1373 00:50:07,579 --> 00:50:09,359 do some really crazy things. 1374 00:50:10,059 --> 00:50:10,559 Is 1375 00:50:11,019 --> 00:50:13,179 this actually been tested then, is it? It 1376 00:50:13,179 --> 00:50:15,500 has indeed, and we do these experiments all 1377 00:50:15,500 --> 00:50:17,980 the time, which is just crazy. They've they've 1378 00:50:18,574 --> 00:50:20,734 so from when it was proposed and it's 1379 00:50:20,734 --> 00:50:23,134 been done in different systems even. That's the 1380 00:50:23,134 --> 00:50:24,674 that's the amazing part. 1381 00:50:25,054 --> 00:50:25,795 And now 1382 00:50:26,094 --> 00:50:26,835 what people 1383 00:50:27,454 --> 00:50:29,775 are actually studying and looking at is the 1384 00:50:29,775 --> 00:50:30,275 interpretation. 1385 00:50:30,654 --> 00:50:32,494 So what does this mean? What does it 1386 00:50:32,494 --> 00:50:34,329 mean if you can do these weak measurements? 1387 00:50:34,390 --> 00:50:36,010 What does it mean if you can separate 1388 00:50:37,269 --> 00:50:39,769 these these things? How does it impact things 1389 00:50:40,150 --> 00:50:42,710 like, you know, the this concept of hidden 1390 00:50:42,710 --> 00:50:44,730 variables? Is there some hidden information 1391 00:50:45,525 --> 00:50:46,585 within these systems, 1392 00:50:46,885 --> 00:50:48,644 or is there something you know, how does 1393 00:50:48,644 --> 00:50:50,804 it all work? And what I really like, 1394 00:50:50,804 --> 00:50:52,565 I'll say this. So this feature was written 1395 00:50:52,565 --> 00:50:55,284 for us by, Julia Georgescu, who is one 1396 00:50:55,284 --> 00:50:57,224 of my colleagues at the IOP in London. 1397 00:50:57,844 --> 00:51:00,105 And she came up with this really 1398 00:51:00,405 --> 00:51:01,019 sort of 1399 00:51:01,500 --> 00:51:02,880 fun idea of, 1400 00:51:03,820 --> 00:51:06,219 cats at a pachinko parlor in Japan. So 1401 00:51:06,219 --> 00:51:07,420 I don't know if you ever heard of 1402 00:51:07,420 --> 00:51:09,579 pachinko. It's, you know, like a slot machine, 1403 00:51:09,579 --> 00:51:11,659 a jackpot thing that they have. And the 1404 00:51:11,659 --> 00:51:13,820 reason why pachinko works really well is that 1405 00:51:13,820 --> 00:51:14,719 in pachinko, 1406 00:51:15,420 --> 00:51:16,320 you have this 1407 00:51:16,655 --> 00:51:18,974 preselection so that the balls that drop from 1408 00:51:18,974 --> 00:51:20,195 the top are in a certain 1409 00:51:21,054 --> 00:51:23,875 spaces, and there is a criteria that determines 1410 00:51:24,655 --> 00:51:26,994 how they will fall through the machine. So 1411 00:51:27,135 --> 00:51:29,480 she has this idea of cats are in 1412 00:51:29,480 --> 00:51:31,019 this pachinko machine, and 1413 00:51:31,480 --> 00:51:33,559 as they go through, you know, you have 1414 00:51:33,559 --> 00:51:35,480 the beam splitter and the the sort of 1415 00:51:35,480 --> 00:51:37,819 the cat is on on one end and 1416 00:51:38,039 --> 00:51:40,039 the the the chair that you sit on 1417 00:51:40,039 --> 00:51:41,204 to play these slots 1418 00:51:41,605 --> 00:51:43,285 has the grin. So the cat is on 1419 00:51:43,285 --> 00:51:45,045 the machine and the grin is on the 1420 00:51:45,045 --> 00:51:47,684 chair. And so it's an interesting way of 1421 00:51:47,684 --> 00:51:49,925 thinking of this very curious phenomenon. And and, 1422 00:51:49,925 --> 00:51:50,585 you know, I mentioned photons, 1423 00:51:51,844 --> 00:51:52,344 but 1424 00:51:53,250 --> 00:51:56,243 same thing happens with any quantum particle, really. 1425 00:51:56,243 --> 00:51:59,236 So with an electron, you can do the 1426 00:51:59,236 --> 00:52:02,229 same thing with its charge. With a neutron, 1427 00:52:02,229 --> 00:52:05,222 it's it's magnetic moment. And with an atom, 1428 00:52:05,222 --> 00:52:05,971 it's the, 1429 00:52:06,505 --> 00:52:08,744 inertial energy of the atom. So we've tested 1430 00:52:08,744 --> 00:52:10,284 it across all these platforms. 1431 00:52:10,744 --> 00:52:11,565 So, yeah, 1432 00:52:12,505 --> 00:52:14,505 crazy stuff. I don't know if this is 1433 00:52:14,505 --> 00:52:16,125 a silly question. Right? But 1434 00:52:16,425 --> 00:52:16,925 it 1435 00:52:17,385 --> 00:52:20,059 feels to me like we're sort of peeping 1436 00:52:20,119 --> 00:52:22,119 into this world. You know, you peep there's 1437 00:52:22,119 --> 00:52:23,880 that kind of peep but we're peeping into 1438 00:52:23,880 --> 00:52:26,360 this world. And is it is it possible 1439 00:52:26,360 --> 00:52:28,280 that the reason why these things are happening 1440 00:52:28,280 --> 00:52:30,519 is just purely because we're peeping into it 1441 00:52:30,519 --> 00:52:31,980 and there are connections 1442 00:52:32,355 --> 00:52:34,034 that would make total sense if you were 1443 00:52:34,034 --> 00:52:36,594 in it, but because we're sort of peeping 1444 00:52:36,594 --> 00:52:37,255 at it. 1445 00:52:37,954 --> 00:52:39,715 I mean, that is that is a big 1446 00:52:39,715 --> 00:52:41,094 question. That is this 1447 00:52:41,474 --> 00:52:43,875 fundamental, you know, one of those that's that's 1448 00:52:43,875 --> 00:52:46,534 also something else that's really interesting that hopefully, 1449 00:52:47,869 --> 00:52:49,550 we'll get some answers to words. They say 1450 00:52:49,550 --> 00:52:50,910 now physics world live, 1451 00:52:51,309 --> 00:52:53,550 that will be published by the time you 1452 00:52:53,550 --> 00:52:54,690 listen to this podcast. 1453 00:52:55,949 --> 00:52:58,750 This idea that there are these inherent quantum 1454 00:52:58,750 --> 00:53:00,989 fundamental questions that a hundred years later, we 1455 00:53:00,989 --> 00:53:03,864 really have no answers to. But what's interesting 1456 00:53:03,864 --> 00:53:05,404 is that we now technologically 1457 00:53:05,704 --> 00:53:08,264 advance so much. The fact that we can 1458 00:53:08,264 --> 00:53:10,284 have entangled states between, 1459 00:53:11,065 --> 00:53:12,924 an atom in the lab and an atom, 1460 00:53:13,304 --> 00:53:15,304 up in space. Right? We've done it. We're 1461 00:53:15,304 --> 00:53:17,724 seeing it. We're still not quite sure what's 1462 00:53:17,900 --> 00:53:20,640 how and what. So these interpretations 1463 00:53:21,099 --> 00:53:22,940 of it is what physicists are still trying 1464 00:53:22,940 --> 00:53:24,320 to figure out. But there's 1465 00:53:24,780 --> 00:53:26,699 this really, we're in a great position where 1466 00:53:26,699 --> 00:53:28,780 we can use the technology that we have 1467 00:53:28,780 --> 00:53:29,920 today to probe 1468 00:53:30,344 --> 00:53:31,085 these fundamental 1469 00:53:31,465 --> 00:53:33,704 questions and try and figure out. So there 1470 00:53:33,704 --> 00:53:35,784 is a big question about the act of 1471 00:53:35,784 --> 00:53:36,844 measurement itself 1472 00:53:37,625 --> 00:53:40,125 in quantum mechanics, the act of observation 1473 00:53:40,585 --> 00:53:42,605 itself in quantum mechanics and 1474 00:53:43,150 --> 00:53:45,070 the role that plays. And that's sort of 1475 00:53:45,070 --> 00:53:47,389 what Bohr and Einstein were arguing about from 1476 00:53:47,389 --> 00:53:49,409 the start. And we still don't have 1477 00:53:49,869 --> 00:53:52,030 a very definitive answer. We do all these 1478 00:53:52,030 --> 00:53:54,449 experiments, but we still can't quite 1479 00:53:55,309 --> 00:53:56,769 explain how and why. 1480 00:53:57,094 --> 00:53:59,014 And that actually I won't go into it 1481 00:53:59,014 --> 00:54:00,775 in too much detail because it is really 1482 00:54:00,775 --> 00:54:03,014 mind boggling and I recommend you read the 1483 00:54:03,014 --> 00:54:05,734 article. But it brings us quite nicely to 1484 00:54:05,734 --> 00:54:08,375 the third effect in the feature in the 1485 00:54:08,375 --> 00:54:10,315 in the briefing, which is the quantum 1486 00:54:10,650 --> 00:54:13,230 eraser or the quantum eraser and the delayed 1487 00:54:13,289 --> 00:54:14,349 choice experiment 1488 00:54:14,969 --> 00:54:16,969 as it is called. And that's this crazy 1489 00:54:16,969 --> 00:54:19,069 thing of, you know, most of us 1490 00:54:19,369 --> 00:54:20,349 when you're at university, 1491 00:54:21,049 --> 00:54:23,210 you learn about the double slit experiments. If 1492 00:54:23,210 --> 00:54:24,969 you have a single light source, you send 1493 00:54:24,969 --> 00:54:25,630 a photon 1494 00:54:26,034 --> 00:54:28,034 towards a double slit that is really quite 1495 00:54:28,034 --> 00:54:28,534 tiny. 1496 00:54:29,235 --> 00:54:31,414 Even though it's a single photon because 1497 00:54:31,715 --> 00:54:33,574 light occasionally acts like a wave, 1498 00:54:34,355 --> 00:54:36,755 it's sort of that single photon passes through 1499 00:54:36,755 --> 00:54:38,994 both of the slits. And if you have 1500 00:54:38,994 --> 00:54:40,769 a screen at the other side of it, 1501 00:54:40,929 --> 00:54:43,570 you see this amazing interference pattern. So the 1502 00:54:43,570 --> 00:54:45,429 photon has interfered with itself. 1503 00:54:46,050 --> 00:54:48,289 But the crazy thing is that if you 1504 00:54:48,289 --> 00:54:50,789 have that very same setup, but now 1505 00:54:51,090 --> 00:54:52,949 you put some kind of detector 1506 00:54:53,250 --> 00:54:56,309 on each individual slit so you can measure 1507 00:54:56,885 --> 00:54:57,385 which 1508 00:54:57,844 --> 00:55:00,484 slit that atom goes through. The minute you 1509 00:55:00,484 --> 00:55:02,585 measure, you record that information, 1510 00:55:03,284 --> 00:55:05,144 the interference pattern disappears. 1511 00:55:06,164 --> 00:55:09,204 The the the yeah. The light refuses to 1512 00:55:09,204 --> 00:55:10,644 let you know what it's gone. It goes, 1513 00:55:10,644 --> 00:55:12,579 no. No. If if you do that, I'm 1514 00:55:12,579 --> 00:55:14,019 not doing it. I'm going through one or 1515 00:55:14,019 --> 00:55:15,619 the other. And so it just turns into 1516 00:55:15,619 --> 00:55:18,260 that Those dark and light bands disappear. And 1517 00:55:18,260 --> 00:55:19,699 this is something you do in the lab 1518 00:55:19,699 --> 00:55:22,340 and it's it's crazy. It's like how does 1519 00:55:22,340 --> 00:55:24,885 it know? So that that in itself is 1520 00:55:24,885 --> 00:55:26,664 this the role of the observer, 1521 00:55:26,965 --> 00:55:28,184 right, and and what 1522 00:55:28,565 --> 00:55:29,625 this information 1523 00:55:30,724 --> 00:55:33,765 that is how how crucial information is in 1524 00:55:33,765 --> 00:55:34,744 quantum systems. 1525 00:55:35,204 --> 00:55:37,525 But then to make things really, really mind 1526 00:55:37,525 --> 00:55:39,650 boggling, the point of the quantum eraser 1527 00:55:40,030 --> 00:55:40,769 is that 1528 00:55:41,630 --> 00:55:42,449 once again, 1529 00:55:42,750 --> 00:55:43,889 if you sort of 1530 00:55:44,190 --> 00:55:47,010 delay the choice so what if you don't 1531 00:55:47,469 --> 00:55:47,969 measure 1532 00:55:48,510 --> 00:55:49,489 at the slit 1533 00:55:49,789 --> 00:55:51,869 which slit it goes through, but you somehow 1534 00:55:51,869 --> 00:55:52,609 have something 1535 00:55:52,989 --> 00:55:54,130 past the slit 1536 00:55:54,695 --> 00:55:56,394 that measures the interference. 1537 00:55:57,094 --> 00:55:59,414 And then it kind of tries and looks 1538 00:55:59,414 --> 00:55:59,914 at 1539 00:56:00,295 --> 00:56:02,775 what's coming from the left hand side slit 1540 00:56:02,775 --> 00:56:04,614 versus the right hand slide. So and, again, 1541 00:56:04,614 --> 00:56:06,855 brings us to these weak measurements. So you 1542 00:56:06,855 --> 00:56:08,534 look at it weekly and you add it 1543 00:56:08,534 --> 00:56:08,969 up, 1544 00:56:09,449 --> 00:56:12,030 then you get that interference pattern back up. 1545 00:56:12,570 --> 00:56:15,050 So it's this idea of what if you 1546 00:56:15,050 --> 00:56:15,550 delay 1547 00:56:16,090 --> 00:56:17,710 the choice of measuring it. 1548 00:56:18,329 --> 00:56:20,570 And what's truly mind boggling with that, the 1549 00:56:20,570 --> 00:56:22,489 sort of why we're talking about, does it 1550 00:56:22,489 --> 00:56:23,565 rewrite the past? 1551 00:56:24,045 --> 00:56:27,264 Because this very same concept of this so 1552 00:56:27,644 --> 00:56:28,944 so John Wheeler, 1553 00:56:30,125 --> 00:56:31,184 the very famous 1554 00:56:31,644 --> 00:56:34,444 quantum physicist and and thinker, I would say, 1555 00:56:34,444 --> 00:56:35,699 he said that 1556 00:56:37,139 --> 00:56:39,380 so what if you take starlight from a 1557 00:56:39,380 --> 00:56:42,099 star that's millions of light years away and 1558 00:56:42,099 --> 00:56:44,920 you do this double slit experiment with it, 1559 00:56:44,980 --> 00:56:47,300 but then you you measure which slit is 1560 00:56:47,300 --> 00:56:50,045 going through? Are you are we saying that 1561 00:56:50,045 --> 00:56:52,444 we can control the starlight and what it 1562 00:56:52,444 --> 00:56:54,605 does? Are we making it change what it 1563 00:56:54,605 --> 00:56:55,105 did 1564 00:56:55,565 --> 00:56:57,824 in the past by measuring it 1565 00:56:58,125 --> 00:56:59,984 in the present? That's just 1566 00:57:00,525 --> 00:57:03,179 crazy. So so that was his big question. 1567 00:57:03,179 --> 00:57:04,880 He's like, what does that mean? 1568 00:57:05,980 --> 00:57:06,480 And 1569 00:57:06,940 --> 00:57:09,260 so I think what most scientists believe today 1570 00:57:09,260 --> 00:57:09,920 is that 1571 00:57:10,380 --> 00:57:13,099 it isn't really this there is it isn't 1572 00:57:13,099 --> 00:57:15,840 that you're actually having a path and influence 1573 00:57:15,900 --> 00:57:17,824 in the past or that you are rewriting 1574 00:57:17,885 --> 00:57:18,545 the past. 1575 00:57:18,925 --> 00:57:21,664 It's just that there is this truly quantum 1576 00:57:22,525 --> 00:57:23,025 inherently 1577 00:57:23,565 --> 00:57:24,784 quantum effect 1578 00:57:25,324 --> 00:57:26,545 or quantum correlation 1579 00:57:27,005 --> 00:57:29,485 that happens because of entanglement that we still 1580 00:57:29,485 --> 00:57:31,505 don't understand, but we just have to appreciate 1581 00:57:31,780 --> 00:57:33,880 that it is not something that we can 1582 00:57:34,180 --> 00:57:34,680 put 1583 00:57:35,300 --> 00:57:38,099 as simply in classical terms as rewriting the 1584 00:57:38,099 --> 00:57:38,599 past. 1585 00:57:39,220 --> 00:57:41,559 And, again, that even that, there there's experiments 1586 00:57:41,700 --> 00:57:43,940 on this that people are doing and trying 1587 00:57:43,940 --> 00:57:45,480 to make more sense of 1588 00:57:46,545 --> 00:57:47,045 this 1589 00:57:47,344 --> 00:57:48,885 link between information, 1590 00:57:49,824 --> 00:57:50,324 observers, 1591 00:57:50,704 --> 00:57:53,344 and quantum competing even. So it's not all 1592 00:57:53,344 --> 00:57:55,905 just very esoteric thinking. It starts out that 1593 00:57:55,905 --> 00:57:59,125 way, but it always has quite practical implications. 1594 00:58:00,909 --> 00:58:03,070 Yeah. That's an interesting thing, isn't it? Because 1595 00:58:03,070 --> 00:58:05,789 I really recommend people do lean into that 1596 00:58:05,789 --> 00:58:08,190 and and read fully the article and really, 1597 00:58:08,190 --> 00:58:10,110 you know, get into it because Mhmm. I 1598 00:58:10,110 --> 00:58:11,789 don't know about you, but I find myself 1599 00:58:11,789 --> 00:58:13,710 looking at the news and the newspapers and 1600 00:58:13,710 --> 00:58:15,394 things, and I just I just find the 1601 00:58:15,394 --> 00:58:17,414 world a very odd place at the moment. 1602 00:58:17,474 --> 00:58:19,554 And it's much more fun to look into 1603 00:58:19,554 --> 00:58:21,795 something like this with my spare time than 1604 00:58:21,795 --> 00:58:23,474 it is to look into to the news. 1605 00:58:23,474 --> 00:58:24,534 But is there 1606 00:58:25,074 --> 00:58:25,974 a kind of, 1607 00:58:26,914 --> 00:58:28,440 application of this stuff? 1608 00:58:29,000 --> 00:58:31,420 The applications of this in society, what 1609 00:58:31,719 --> 00:58:32,859 what other possible 1610 00:58:33,800 --> 00:58:36,519 apart from just making me happier Yes. When 1611 00:58:36,519 --> 00:58:38,679 I go to bed. Absolutely. So like I 1612 00:58:38,679 --> 00:58:40,760 said, there there are hopefully I mean, from 1613 00:58:40,760 --> 00:58:41,260 what 1614 00:58:42,195 --> 00:58:44,695 scientists and governments across the world are hoping 1615 00:58:44,835 --> 00:58:47,715 is that the sort of quantum renaissance will 1616 00:58:47,715 --> 00:58:49,735 have such a deep impact on our lives, 1617 00:58:50,434 --> 00:58:52,994 in the long term because, really, what you 1618 00:58:52,994 --> 00:58:53,655 can do 1619 00:58:54,035 --> 00:58:54,775 with quantum 1620 00:58:55,394 --> 00:58:57,894 computing, quantum sensors, and other quantum 1621 00:58:58,809 --> 00:58:59,250 technologies, 1622 00:58:59,690 --> 00:59:01,949 is is hopefully going to be wide ranging 1623 00:59:03,130 --> 00:59:06,089 and and truly amazing once we achieve it. 1624 00:59:06,089 --> 00:59:08,109 We could talk a bit about quantum computing, 1625 00:59:08,170 --> 00:59:10,569 but perhaps that's still something that's in the 1626 00:59:10,569 --> 00:59:12,190 making. We don't have 1627 00:59:12,644 --> 00:59:15,045 a definitive quantum computer, and that can do 1628 00:59:15,045 --> 00:59:17,304 something really useful as of now 1629 00:59:17,605 --> 00:59:20,005 that we can't do with classical computing. Our 1630 00:59:20,005 --> 00:59:21,125 sort of massive 1631 00:59:21,605 --> 00:59:24,085 you know, the bigger supercomputers that we have 1632 00:59:24,085 --> 00:59:26,724 still outperform what the best quantum computer can 1633 00:59:26,724 --> 00:59:29,110 do today. But that doesn't mean we shouldn't 1634 00:59:29,110 --> 00:59:31,210 be building towards it. And that's something 1635 00:59:31,590 --> 00:59:33,829 that we're gonna hopefully dig into in a 1636 00:59:33,829 --> 00:59:35,909 big way in our second volume of the 1637 00:59:35,909 --> 00:59:38,230 quantum briefing that's gonna come later in the 1638 00:59:38,230 --> 00:59:40,364 year. That's a little teaser for you. But 1639 00:59:40,364 --> 00:59:41,724 one of the things that I love to 1640 00:59:41,724 --> 00:59:44,385 talk about is the area of quantum sensors. 1641 00:59:45,405 --> 00:59:47,164 So we talked a little bit about how, 1642 00:59:47,164 --> 00:59:49,164 you know, quantum systems, you set it up 1643 00:59:49,164 --> 00:59:51,164 and then you measure it and it quickly 1644 00:59:51,164 --> 00:59:53,105 sort of collapses. You have this decoherence. 1645 00:59:53,644 --> 00:59:55,469 So they're extremely sensitive 1646 00:59:55,930 --> 00:59:56,829 to the environment. 1647 00:59:57,210 --> 00:59:59,450 And someone ages ago thought, wait a minute. 1648 00:59:59,450 --> 01:00:01,769 They're really, really sensitive to everything going on 1649 01:00:01,769 --> 01:00:04,010 around them. That could be a feature. It's 1650 01:00:04,010 --> 01:00:06,010 something that we've been taking as a as 1651 01:00:06,010 --> 01:00:07,450 a pain in the ass for all our 1652 01:00:07,450 --> 01:00:07,950 experiments. 1653 01:00:08,664 --> 01:00:09,404 But actually, 1654 01:00:10,184 --> 01:00:12,184 it's gonna be something that could be quite 1655 01:00:12,184 --> 01:00:14,364 useful. What if I try and use these 1656 01:00:14,424 --> 01:00:16,605 very sensitive things as a sensor? 1657 01:00:17,144 --> 01:00:19,464 And so that scenario of physics that, you 1658 01:00:19,464 --> 01:00:20,684 know, quantum sensors 1659 01:00:21,065 --> 01:00:21,565 are 1660 01:00:21,949 --> 01:00:24,349 way ahead in terms of they're being used 1661 01:00:24,349 --> 01:00:26,849 in real life already. They're out of 1662 01:00:27,230 --> 01:00:29,710 the labs and and and being tested in 1663 01:00:29,710 --> 01:00:31,329 many spaces. And, 1664 01:00:33,469 --> 01:00:35,730 Catherine Skipper, who was features editor, 1665 01:00:36,109 --> 01:00:38,534 with us for last year, she's written this 1666 01:00:38,534 --> 01:00:41,734 brilliant feature in the guide about quantum based 1667 01:00:41,734 --> 01:00:42,875 gravity sensors. 1668 01:00:43,414 --> 01:00:45,114 And that's really interesting because 1669 01:00:45,494 --> 01:00:48,155 really often, we need to look at things, 1670 01:00:49,255 --> 01:00:51,130 that are buried under ground. And this is 1671 01:00:51,130 --> 01:00:52,909 really important for construction 1672 01:00:53,289 --> 01:00:55,230 or anyone who's doing anything 1673 01:00:55,929 --> 01:00:58,250 that is underground and that's, you know, under 1674 01:00:58,250 --> 01:01:00,650 a road, in a residential area, under a 1675 01:01:00,650 --> 01:01:02,110 mountain, under the sea. 1676 01:01:02,744 --> 01:01:04,764 There's many options of that. And 1677 01:01:05,625 --> 01:01:06,525 we can use, 1678 01:01:07,304 --> 01:01:09,944 cold atom interferometry, which is this idea of 1679 01:01:09,944 --> 01:01:10,924 falling atoms 1680 01:01:11,304 --> 01:01:12,125 to to 1681 01:01:12,904 --> 01:01:15,780 test what's going on under the ground. And 1682 01:01:15,780 --> 01:01:17,619 you might say, well, there's plenty of ways 1683 01:01:17,619 --> 01:01:19,140 to test that. You know, you have radar 1684 01:01:19,140 --> 01:01:20,340 and this and that, and we have so 1685 01:01:20,340 --> 01:01:21,000 many things. 1686 01:01:21,380 --> 01:01:24,099 But the thing is whether whether you're doing 1687 01:01:24,099 --> 01:01:26,519 something for the government or you're a construction 1688 01:01:26,579 --> 01:01:28,664 firm trying to figure out what's going on 1689 01:01:28,905 --> 01:01:29,644 on a road. 1690 01:01:30,425 --> 01:01:32,664 Measurements for these kind of things can take 1691 01:01:32,664 --> 01:01:34,204 weeks and months sometimes. 1692 01:01:34,824 --> 01:01:37,065 They take really long. They're not as accurate 1693 01:01:37,065 --> 01:01:39,065 as you like them. And, you know, the 1694 01:01:39,065 --> 01:01:41,144 last thing you want is a road closed 1695 01:01:41,144 --> 01:01:42,989 for a month because they're just trying to 1696 01:01:42,989 --> 01:01:44,909 figure out where the water mains are. Or 1697 01:01:44,909 --> 01:01:46,590 worse, they've got it wrong and there's a 1698 01:01:46,590 --> 01:01:48,269 hole in your water pipe, and now your 1699 01:01:48,269 --> 01:01:49,890 road's closed and you have no water. 1700 01:01:51,710 --> 01:01:53,710 So that's some of the stuff that some 1701 01:01:53,710 --> 01:01:56,510 of these quantum sensors are looking at, these 1702 01:01:56,510 --> 01:01:59,494 gravity based quantum sensors. The University of Birmingham 1703 01:01:59,554 --> 01:02:00,454 has a huge, 1704 01:02:01,315 --> 01:02:05,155 team, a collaboration working on many different aspects 1705 01:02:05,155 --> 01:02:06,454 of this kind of stuff, 1706 01:02:07,714 --> 01:02:08,934 with quantum gravimeters. 1707 01:02:09,474 --> 01:02:11,809 I think it's some really fascinating stuff. 1708 01:02:12,190 --> 01:02:14,670 They've they've been testing it in exciting places 1709 01:02:14,670 --> 01:02:15,570 like an underground 1710 01:02:16,030 --> 01:02:17,809 cavern in the Peak District 1711 01:02:18,670 --> 01:02:20,590 and out at sea in the in out 1712 01:02:20,590 --> 01:02:21,970 at sea in the North Sea, 1713 01:02:22,674 --> 01:02:23,494 with the navy. 1714 01:02:23,875 --> 01:02:26,194 They've been testing, and that's all part of 1715 01:02:26,194 --> 01:02:29,234 The UK's quantum technology hub for sensors and 1716 01:02:29,234 --> 01:02:29,734 timing. 1717 01:02:30,434 --> 01:02:31,255 So it's 1718 01:02:31,554 --> 01:02:34,355 some amazing stuff that's already out there. The 1719 01:02:34,355 --> 01:02:36,135 the quantum is already being 1720 01:02:36,719 --> 01:02:38,179 used in the real world. 1721 01:02:38,559 --> 01:02:40,739 It's lovely, lovely stuff. I think, 1722 01:02:41,360 --> 01:02:43,840 we should probably allow people to stop listening 1723 01:02:43,840 --> 01:02:45,679 to this podcast and start reading the quantum 1724 01:02:45,679 --> 01:02:47,199 briefing. How do they do that if they 1725 01:02:47,199 --> 01:02:48,500 would like to find it? 1726 01:02:49,199 --> 01:02:52,184 So it's the quantum briefing is free to 1727 01:02:52,184 --> 01:02:56,105 read and access to everyone online on physicsworld.com. 1728 01:02:56,105 --> 01:02:58,605 If you just click through to our magazines 1729 01:02:58,744 --> 01:03:00,505 tab and you look at all of the 1730 01:03:00,505 --> 01:03:02,184 magazines lined up for this year, you will 1731 01:03:02,184 --> 01:03:02,684 see 1732 01:03:02,985 --> 01:03:04,664 you you can read it online in a 1733 01:03:04,664 --> 01:03:06,425 nice flip book. You can download it in 1734 01:03:06,425 --> 01:03:07,005 a PDF, 1735 01:03:07,409 --> 01:03:09,329 all the options, and it's free to read 1736 01:03:09,329 --> 01:03:09,989 and access. 1737 01:03:10,369 --> 01:03:13,109 And it also includes little bits of audio 1738 01:03:13,250 --> 01:03:15,889 and podcasts and so you can hear people 1739 01:03:15,889 --> 01:03:18,609 talking about it. You can find out what 1740 01:03:18,609 --> 01:03:21,250 author Ursula Caleb Gwynn had to do with 1741 01:03:21,250 --> 01:03:22,869 Schrodinger's cat. Amazing. 1742 01:03:24,025 --> 01:03:26,204 You can look at that beautiful quantum artwork. 1743 01:03:26,824 --> 01:03:28,525 You can look at an absolutely 1744 01:03:28,824 --> 01:03:31,085 fascinating little bit of science fiction 1745 01:03:31,784 --> 01:03:33,465 on on what happened if, 1746 01:03:33,945 --> 01:03:35,885 Heisenberg never made it to Helgoland 1747 01:03:36,184 --> 01:03:38,929 and what happens when he did a little 1748 01:03:39,309 --> 01:03:40,429 a little sort of, 1749 01:03:41,150 --> 01:03:42,130 parallel situation. 1750 01:03:43,230 --> 01:03:45,789 And finally, you can also go and test 1751 01:03:45,789 --> 01:03:48,829 your quantum acumen with our quantum quiz on 1752 01:03:48,829 --> 01:03:50,190 the back page for a little bit of 1753 01:03:50,190 --> 01:03:52,075 fun. And there are no prizes for that 1754 01:03:52,075 --> 01:03:53,934 apart from feeling extremely clever. 1755 01:03:54,795 --> 01:03:56,954 I'd like to thank Felicity and Tushna for 1756 01:03:56,954 --> 01:03:58,394 talking to me for this episode of the 1757 01:03:58,394 --> 01:04:00,795 Physics World Stories podcast. And don't forget that 1758 01:04:00,795 --> 01:04:02,954 you can delve much deeper into the world 1759 01:04:02,954 --> 01:04:05,295 of quantum physics on the Physics World's website, 1760 01:04:05,355 --> 01:04:06,750 physicsworld.com, 1761 01:04:06,750 --> 01:04:09,010 where you will, of course, also find 1762 01:04:09,309 --> 01:04:12,369 those blogs from Mateen Jurani from Helgoland. 1763 01:04:12,829 --> 01:04:15,070 We'll be back next month with something else 1764 01:04:15,070 --> 01:04:17,230 from this wonderful world of physics, and thank 1765 01:04:17,230 --> 01:04:19,090 you very much for listening.
