1 00:00:04,120 --> 00:00:07,160 Speaker 1: Get in touch with technology with tech Stuff from how 2 00:00:07,200 --> 00:00:14,240 Speaker 1: stuff Works dot com. Hey there, and welcome to Tech Stuff. 3 00:00:14,280 --> 00:00:17,360 Speaker 1: I'm your host, Jonathan Strickland. I'm an executive producer with 4 00:00:17,400 --> 00:00:19,600 Speaker 1: How Stuff Works in I heart radio and I love 5 00:00:19,680 --> 00:00:23,680 Speaker 1: all things tech, and today we have a very special 6 00:00:23,880 --> 00:00:29,720 Speaker 1: guest on our show, someone who has worked on really 7 00:00:29,800 --> 00:00:33,360 Speaker 1: interesting problems. Is a rare occasion that I get to 8 00:00:33,400 --> 00:00:38,800 Speaker 1: talk to someone who has experienced in high energy particle physics. 9 00:00:38,800 --> 00:00:41,839 Speaker 1: So I want to introduce to all of you, if 10 00:00:41,880 --> 00:00:45,320 Speaker 1: you haven't listened to his amazing podcast yet, Daniel Whitson. 11 00:00:45,440 --> 00:00:49,440 Speaker 1: Dr Daniel Whitson that Welcome to the show. Hi, thanks 12 00:00:49,479 --> 00:00:51,680 Speaker 1: a lot for having me on. I am so glad 13 00:00:51,720 --> 00:00:55,440 Speaker 1: to have you here now. Daniel, you are one half 14 00:00:55,800 --> 00:00:59,680 Speaker 1: of the podcast team of Daniel and Jorge Explained the Universe, 15 00:00:59,720 --> 00:01:03,000 Speaker 1: and thank you for taking time away from explaining the 16 00:01:03,080 --> 00:01:07,440 Speaker 1: universe to grace my humble show with your presence. I 17 00:01:07,520 --> 00:01:10,520 Speaker 1: greatly appreciate it. Well, thanks a lot for having me on. 18 00:01:10,600 --> 00:01:13,040 Speaker 1: You guys talk about really fascinating stuff, so it's a 19 00:01:13,040 --> 00:01:16,640 Speaker 1: pleasure to be here. It's been a pleasure listening to 20 00:01:16,720 --> 00:01:18,600 Speaker 1: your show. We'll talk a little bit more about that 21 00:01:18,640 --> 00:01:21,240 Speaker 1: towards the end of the episode, but just so that 22 00:01:21,360 --> 00:01:26,080 Speaker 1: my listeners kind of understand where you you're coming from 23 00:01:26,120 --> 00:01:29,920 Speaker 1: before we get into work with the Large Hadron Collider 24 00:01:29,920 --> 00:01:33,680 Speaker 1: and CERN and particle physics. Tell us a bit about yourself, 25 00:01:33,959 --> 00:01:36,800 Speaker 1: all right, Well, I'm devastatingly good looking, which is why 26 00:01:36,800 --> 00:01:42,440 Speaker 1: I have a podcast, and m familiar my my. The 27 00:01:42,440 --> 00:01:44,399 Speaker 1: most important thing to know about me in this context, 28 00:01:44,440 --> 00:01:47,000 Speaker 1: I guess, is that I am a high energy physicist, 29 00:01:47,360 --> 00:01:50,440 Speaker 1: which means that I'm interested in studying the universe at 30 00:01:50,440 --> 00:01:54,440 Speaker 1: the smallest scale, and I do so by smashing stuff 31 00:01:54,480 --> 00:01:56,960 Speaker 1: together at the highest energy. It's like, you know, you 32 00:01:57,000 --> 00:01:59,760 Speaker 1: want to understand how things work, take them apart, and 33 00:01:59,800 --> 00:02:01,600 Speaker 1: that basically what we do is we try to take 34 00:02:01,640 --> 00:02:04,720 Speaker 1: the whole universe apart and understand how it works. So 35 00:02:04,920 --> 00:02:08,080 Speaker 1: I'm a professor at the University of California at Irvine 36 00:02:08,120 --> 00:02:11,520 Speaker 1: that's in Orange County and m I work there, and 37 00:02:11,560 --> 00:02:14,000 Speaker 1: I work also at the Large Hadron Collider in Geneva 38 00:02:14,160 --> 00:02:17,519 Speaker 1: where the actual collider is, and we have a big 39 00:02:17,520 --> 00:02:20,200 Speaker 1: team of people smashing particles together and trying to figure 40 00:02:20,200 --> 00:02:22,440 Speaker 1: out what is the smallest bit of matter and how 41 00:02:22,480 --> 00:02:25,440 Speaker 1: does it all fit together? And where, how did everything start? 42 00:02:25,520 --> 00:02:27,720 Speaker 1: And how is it going to end? And we basically 43 00:02:27,720 --> 00:02:31,440 Speaker 1: try to tackle those really big sexy questions. Yeah, I 44 00:02:31,440 --> 00:02:34,840 Speaker 1: I love the way you describe that, the idea of 45 00:02:34,880 --> 00:02:39,520 Speaker 1: taking apart the very basic particles that make up stuff 46 00:02:39,800 --> 00:02:43,280 Speaker 1: and and and finding out what makes that work. It's 47 00:02:43,400 --> 00:02:47,279 Speaker 1: very relatable to all the stories of the various innovators 48 00:02:47,280 --> 00:02:50,720 Speaker 1: who got their start taking apart the various pieces of 49 00:02:50,760 --> 00:02:55,200 Speaker 1: technology they have, often to the detriment of their family, 50 00:02:55,400 --> 00:02:57,560 Speaker 1: and then learning how it works and then hopefully being 51 00:02:57,600 --> 00:03:00,080 Speaker 1: able to put it back together again. Except we're looking 52 00:03:00,080 --> 00:03:05,040 Speaker 1: at reality here, how the the very fabric that makes 53 00:03:05,120 --> 00:03:08,880 Speaker 1: up existence works. And uh I also I watched a 54 00:03:09,280 --> 00:03:13,400 Speaker 1: great presentation that you and Jorge gave in which you 55 00:03:13,680 --> 00:03:17,720 Speaker 1: talked about your book and you talked about the gaps 56 00:03:17,800 --> 00:03:21,959 Speaker 1: and scientific knowledge, and that also made me feel like 57 00:03:22,480 --> 00:03:25,400 Speaker 1: I am all a smart person, only because in the 58 00:03:25,440 --> 00:03:29,519 Speaker 1: past I have described our understanding of the universe like 59 00:03:29,639 --> 00:03:32,399 Speaker 1: we're staring through a key hole and we can only 60 00:03:32,440 --> 00:03:35,600 Speaker 1: see a little bit of the illuminated room that's beyond 61 00:03:35,640 --> 00:03:38,120 Speaker 1: the keyhole, and there's stuff and shadows, So there are 62 00:03:38,160 --> 00:03:41,120 Speaker 1: things that we don't really see, and there are elements 63 00:03:41,160 --> 00:03:43,360 Speaker 1: that are out of you and to us. That's that's 64 00:03:43,400 --> 00:03:45,720 Speaker 1: our understanding of the universe. We only see a very 65 00:03:45,800 --> 00:03:51,320 Speaker 1: narrow band of what really exists out there, and our 66 00:03:51,400 --> 00:03:55,680 Speaker 1: goal is to expand that over time. That's right, and 67 00:03:55,720 --> 00:03:58,720 Speaker 1: the most amazing thing in my perspective is that we've 68 00:03:58,760 --> 00:04:02,160 Speaker 1: only recently disc covered that we are looking through the keyhole. 69 00:04:02,240 --> 00:04:03,640 Speaker 1: I mean, for a long time we thought we were 70 00:04:03,640 --> 00:04:05,920 Speaker 1: saying everything. We thought, well, we've seen the way the 71 00:04:06,000 --> 00:04:07,800 Speaker 1: universe is now, we just need to figure out how 72 00:04:07,840 --> 00:04:10,000 Speaker 1: to explain it. We made a lot of progress and 73 00:04:10,040 --> 00:04:13,160 Speaker 1: the last fifty year, in the last twenty or fifty years, 74 00:04:13,440 --> 00:04:15,520 Speaker 1: we've discovered that there's a lot of stuff out there 75 00:04:15,520 --> 00:04:19,240 Speaker 1: that we don't have any understanding of, dark matter, dark energy, 76 00:04:19,760 --> 00:04:24,000 Speaker 1: huge chunks of the universe which completely defy our our explanation. 77 00:04:24,200 --> 00:04:26,279 Speaker 1: That doesn't mean it can't be explained. You don't have 78 00:04:26,320 --> 00:04:28,839 Speaker 1: to go to like weird woo woo crystal energy stuff. 79 00:04:28,839 --> 00:04:31,360 Speaker 1: It just means that there's a lot more science left 80 00:04:31,360 --> 00:04:34,080 Speaker 1: to do. And for me, those are wonderful moments in 81 00:04:34,080 --> 00:04:36,240 Speaker 1: the history of science when you you know, you pull 82 00:04:36,279 --> 00:04:39,120 Speaker 1: back a layer of reality and discover, oh my gosh, wow, 83 00:04:39,200 --> 00:04:42,039 Speaker 1: things are totally different from what we expected, or you know, 84 00:04:42,040 --> 00:04:44,440 Speaker 1: it turns out we were only studying the the tail 85 00:04:44,480 --> 00:04:45,960 Speaker 1: of the elephant, and we need to look at the 86 00:04:45,960 --> 00:04:48,719 Speaker 1: rest of it. And and that's exciting. Not because the 87 00:04:48,760 --> 00:04:51,680 Speaker 1: science is humbled and realizing that we don't understand everything, 88 00:04:51,720 --> 00:04:54,719 Speaker 1: that's that's a wonderful experience. It's exciting because it means 89 00:04:54,720 --> 00:04:57,520 Speaker 1: there are discoveries left to come, right. I mean that 90 00:04:57,680 --> 00:05:01,719 Speaker 1: maybe some of the most dramatic, most insightful realizations about 91 00:05:01,720 --> 00:05:04,040 Speaker 1: the nature of the universe might still be ahead of us. 92 00:05:04,600 --> 00:05:06,600 Speaker 1: I like thinking about how in the future and a 93 00:05:06,640 --> 00:05:10,920 Speaker 1: hundred years people might look back with great knowledge of 94 00:05:10,920 --> 00:05:13,840 Speaker 1: how the universe works and wonder what it was like 95 00:05:13,960 --> 00:05:16,600 Speaker 1: to be us when we lived in such ignorance, right 96 00:05:16,920 --> 00:05:19,440 Speaker 1: when we didn't know so many things about so many 97 00:05:19,480 --> 00:05:23,039 Speaker 1: basic things about the universe. Um and what you said 98 00:05:23,040 --> 00:05:25,680 Speaker 1: earlier really resonate with me about trying to figure things 99 00:05:25,680 --> 00:05:28,280 Speaker 1: out by taking them apart. I think that there's an 100 00:05:28,320 --> 00:05:30,800 Speaker 1: innate curiosity and being human. I mean, that's what makes 101 00:05:30,960 --> 00:05:34,760 Speaker 1: being human fun, it makes being being alive worth It 102 00:05:34,800 --> 00:05:37,200 Speaker 1: is that we are driven by this desire to know 103 00:05:37,440 --> 00:05:40,000 Speaker 1: to understand the things around us. So if you're the 104 00:05:40,040 --> 00:05:42,000 Speaker 1: kind of person who's like, how does a blender work? 105 00:05:42,080 --> 00:05:44,320 Speaker 1: Let me take it apart, or you know, how does 106 00:05:44,400 --> 00:05:46,159 Speaker 1: this thing in my car work? Let me look under 107 00:05:46,200 --> 00:05:49,080 Speaker 1: the hood and poke around. Then you're basically a physicist. 108 00:05:49,120 --> 00:05:51,080 Speaker 1: You're the kind of person who wants to understand things 109 00:05:51,080 --> 00:05:53,240 Speaker 1: by taking them apart, by boiling them down to the 110 00:05:53,240 --> 00:05:56,880 Speaker 1: most essential elements, and using that to explain your car, 111 00:05:57,000 --> 00:05:59,039 Speaker 1: and then also your blender, and then other things you 112 00:05:59,120 --> 00:06:04,599 Speaker 1: haven't seen. But for right, it's about learning generalizable, universal truths. Yeah, 113 00:06:04,680 --> 00:06:07,920 Speaker 1: and and I would also argue that the history of 114 00:06:07,920 --> 00:06:10,960 Speaker 1: of humanity has been one in which we have attempted 115 00:06:11,000 --> 00:06:15,200 Speaker 1: to explain the why things are the way they are 116 00:06:15,279 --> 00:06:19,159 Speaker 1: for for all of our history, and the as we 117 00:06:19,320 --> 00:06:23,360 Speaker 1: eliminate gaps piece by piece, and knowing that we still 118 00:06:23,400 --> 00:06:26,599 Speaker 1: have enormous gaps left to fill in, we start to 119 00:06:27,440 --> 00:06:30,480 Speaker 1: really hone in on that over time we're able to 120 00:06:30,600 --> 00:06:34,560 Speaker 1: replace things where we had the explanation of a uh. 121 00:06:34,560 --> 00:06:39,119 Speaker 1: Well though, that that's the gods battling it out in Olympus, 122 00:06:39,160 --> 00:06:42,160 Speaker 1: and that's where the thunder comes from. To know now 123 00:06:42,200 --> 00:06:44,320 Speaker 1: we have a deeper understanding to the point now where 124 00:06:44,360 --> 00:06:47,960 Speaker 1: we even are able to get a grasp on the 125 00:06:48,000 --> 00:06:51,920 Speaker 1: idea that as humans, as as we are the way 126 00:06:51,920 --> 00:06:55,920 Speaker 1: we have evolved, we have limitations in our perception. There 127 00:06:56,000 --> 00:06:58,880 Speaker 1: are things that we are capable of perceiving because we 128 00:06:58,920 --> 00:07:02,880 Speaker 1: have evolved. It is advantageous, it made sense in our environment, 129 00:07:03,160 --> 00:07:06,159 Speaker 1: but that doesn't mean that's everything there is out there, 130 00:07:06,240 --> 00:07:09,320 Speaker 1: which kind of leads into discussions that I've heard about, 131 00:07:10,160 --> 00:07:13,560 Speaker 1: you know, the various dimensions that we were capable of perceiving. 132 00:07:13,600 --> 00:07:16,600 Speaker 1: Some of those obviously we can we can observe the 133 00:07:16,600 --> 00:07:19,440 Speaker 1: physical dimensions, and then once you start figuring that out, 134 00:07:19,680 --> 00:07:22,760 Speaker 1: you say, well, it may be a leap to you 135 00:07:23,040 --> 00:07:26,600 Speaker 1: to think there are so many more dimensions or potentially 136 00:07:26,600 --> 00:07:29,440 Speaker 1: more dimensions than the ones we can perceive. But we 137 00:07:29,520 --> 00:07:33,520 Speaker 1: also know that we can't see things in the infrared 138 00:07:33,680 --> 00:07:38,440 Speaker 1: or ultra violet UH wave forms. But with technology, we 139 00:07:38,480 --> 00:07:40,720 Speaker 1: can convert that into light that we can see. And 140 00:07:40,760 --> 00:07:43,200 Speaker 1: once you start looking at things like that level where 141 00:07:43,240 --> 00:07:45,320 Speaker 1: you say, oh, yeah, I guess we have developed tools 142 00:07:45,880 --> 00:07:50,320 Speaker 1: that let us go beyond our limitations in our perception, 143 00:07:50,640 --> 00:07:53,040 Speaker 1: then it kind of opens up your mind into the 144 00:07:53,120 --> 00:07:56,520 Speaker 1: idea of now I kind of understand how there can 145 00:07:56,680 --> 00:07:59,800 Speaker 1: be things like dark energy and dark matter that are 146 00:07:59,840 --> 00:08:03,960 Speaker 1: beyond our current capability of detecting it, because it took 147 00:08:05,040 --> 00:08:06,960 Speaker 1: thousands of years for us to get to the point 148 00:08:06,960 --> 00:08:11,720 Speaker 1: where we could, uh could even indirectly observe stuff like 149 00:08:11,840 --> 00:08:14,440 Speaker 1: being for red in the ultraviolet. So that's sort of 150 00:08:14,440 --> 00:08:16,560 Speaker 1: the approach I take with people as well, the idea 151 00:08:16,640 --> 00:08:19,840 Speaker 1: that it feels like you're taking a big leap when 152 00:08:19,840 --> 00:08:22,160 Speaker 1: you start going into things like particle physics, when you 153 00:08:22,160 --> 00:08:26,320 Speaker 1: start talking about quantum quantum effects, because everything seems so strange. 154 00:08:26,360 --> 00:08:29,640 Speaker 1: It doesn't it doesn't work the way the classical physics work, 155 00:08:30,360 --> 00:08:32,920 Speaker 1: and it's it feels like you're asking people to take 156 00:08:32,920 --> 00:08:34,840 Speaker 1: a leap of faith. But once you start to build 157 00:08:34,840 --> 00:08:37,000 Speaker 1: on those blocks, they say, okay, all right, now I'm 158 00:08:37,000 --> 00:08:39,960 Speaker 1: with you. Now I got it. And that kind of 159 00:08:40,000 --> 00:08:43,120 Speaker 1: brings us over to the work that we see over 160 00:08:43,160 --> 00:08:46,040 Speaker 1: at at CERN and the large Hey drunk collider. Now, 161 00:08:46,640 --> 00:08:49,000 Speaker 1: one thing I like to remind people about as well 162 00:08:49,000 --> 00:08:50,880 Speaker 1: before we get there. I thinks he's touched on a 163 00:08:50,880 --> 00:08:53,800 Speaker 1: really interesting topic there. You know, Um, I think people 164 00:08:53,840 --> 00:08:56,280 Speaker 1: have been thinking about mysteries for a long time, right, 165 00:08:56,760 --> 00:08:59,480 Speaker 1: And for a long time, the world was really mysterious. 166 00:08:59,480 --> 00:09:01,120 Speaker 1: It was obvious that there were mysteries. You could just 167 00:09:01,120 --> 00:09:03,200 Speaker 1: go outside and there were things you didn't understand. What 168 00:09:03,320 --> 00:09:05,920 Speaker 1: is lightning? Right? Um? And it's sort of it was 169 00:09:05,920 --> 00:09:09,040 Speaker 1: a common feeling that the world was mysterious, you know, 170 00:09:09,120 --> 00:09:11,640 Speaker 1: like there are more things in the heavens and earth 171 00:09:11,640 --> 00:09:13,920 Speaker 1: than are dreamt of in your philosophy. Right, it's it's 172 00:09:14,000 --> 00:09:16,520 Speaker 1: even in literature. But we've sort of lost that. I 173 00:09:16,520 --> 00:09:18,800 Speaker 1: think a lot of people these days when they walk around, 174 00:09:19,160 --> 00:09:21,760 Speaker 1: they feel like they mostly understand stuff, like, yeah, we 175 00:09:21,800 --> 00:09:23,880 Speaker 1: know how weather works. Maybe we can't predict it exactly, 176 00:09:23,880 --> 00:09:26,439 Speaker 1: but we understand the mechanism of it and gravity we 177 00:09:26,520 --> 00:09:29,960 Speaker 1: have an understanding of that. And the sense of experiencing 178 00:09:30,040 --> 00:09:33,200 Speaker 1: mystery on a daily basis is sort of gone because 179 00:09:33,200 --> 00:09:36,160 Speaker 1: science has made so much progress in explaining the various 180 00:09:36,200 --> 00:09:39,120 Speaker 1: bits around us. And I want to remind people that 181 00:09:39,480 --> 00:09:43,560 Speaker 1: the bigger questions, the larger questions questions we're asking ourselves, 182 00:09:43,559 --> 00:09:45,480 Speaker 1: like why are we here? How should we live? How? 183 00:09:45,720 --> 00:09:48,200 Speaker 1: What is the history of everything? Those questions are still 184 00:09:48,240 --> 00:09:51,440 Speaker 1: totally unanswered. And uh, And as you said, I think 185 00:09:51,600 --> 00:09:54,560 Speaker 1: is really insightful about how we don't even know what 186 00:09:54,600 --> 00:09:56,960 Speaker 1: we don't know, because there's a lot of things that 187 00:09:57,040 --> 00:09:59,760 Speaker 1: we've only recently discovered. We don't we we didn't understand 188 00:09:59,840 --> 00:10:02,440 Speaker 1: right that there's things happening around us that we're not 189 00:10:02,559 --> 00:10:05,920 Speaker 1: aware of, various kinds of particles moving, and even different 190 00:10:06,000 --> 00:10:07,960 Speaker 1: kinds of light that's invisible to us, as you said, 191 00:10:08,440 --> 00:10:10,600 Speaker 1: And there's really no limit on how much of that 192 00:10:10,640 --> 00:10:13,080 Speaker 1: there can be, right, I mean, we know certain things. 193 00:10:13,120 --> 00:10:15,920 Speaker 1: We know dark matter is invisible, we know neutrinos are invisible. 194 00:10:16,240 --> 00:10:18,040 Speaker 1: There could be other things out there that are also 195 00:10:18,080 --> 00:10:20,480 Speaker 1: invisible that we just haven't even yet discovered that they're 196 00:10:20,480 --> 00:10:23,000 Speaker 1: there through some sort of very slight hints. Right. So 197 00:10:23,400 --> 00:10:26,480 Speaker 1: the amount of discoveries left remaining in the future is enormous, 198 00:10:26,480 --> 00:10:29,240 Speaker 1: which is the kind of thing that gets me all excited. Yeah, 199 00:10:29,320 --> 00:10:32,920 Speaker 1: I I have a feeling, Well, first of all, I 200 00:10:32,960 --> 00:10:34,760 Speaker 1: have a feeling I'm gonna need to fly out to 201 00:10:34,840 --> 00:10:37,960 Speaker 1: California and have have like just maybe a four hour 202 00:10:38,080 --> 00:10:40,640 Speaker 1: long conversation with you, because I haven't feeling that's exactly 203 00:10:40,720 --> 00:10:43,360 Speaker 1: what's going to be needed, because I this is the 204 00:10:43,400 --> 00:10:45,720 Speaker 1: source of stuff I love to talk about, just to 205 00:10:45,840 --> 00:10:49,000 Speaker 1: anyone who will, you know, be patient enough to let 206 00:10:49,040 --> 00:10:52,040 Speaker 1: me chatter at them, let me ask you a question 207 00:10:52,040 --> 00:10:54,680 Speaker 1: that you you mentioned about how we used to explain 208 00:10:54,720 --> 00:10:56,520 Speaker 1: things in terms of gods, and I think that makes 209 00:10:56,559 --> 00:10:58,760 Speaker 1: a lot of sense because humans are good at like 210 00:10:58,800 --> 00:11:04,080 Speaker 1: identifying agency and willfulness in places where there aren't any, Right. 211 00:11:04,160 --> 00:11:05,880 Speaker 1: But there's another element to that, which is the sort 212 00:11:05,920 --> 00:11:08,960 Speaker 1: of the narrative. Right, These gods don't just have personalities 213 00:11:08,960 --> 00:11:11,360 Speaker 1: and wheels that had stories that reasons why they were 214 00:11:11,360 --> 00:11:14,360 Speaker 1: doing what they were doing. And I feel like storytelling 215 00:11:14,440 --> 00:11:16,480 Speaker 1: is a big part of who we are as a species. 216 00:11:16,679 --> 00:11:18,680 Speaker 1: And it's still even though we're not explaining things in 217 00:11:18,760 --> 00:11:22,040 Speaker 1: terms of God's it still drives our science. Like you know, 218 00:11:22,080 --> 00:11:24,520 Speaker 1: if you asked me, um, what would you do if 219 00:11:24,520 --> 00:11:26,679 Speaker 1: you knew the final answer to particle physics, Like if 220 00:11:26,720 --> 00:11:30,440 Speaker 1: you could explain the whole universe in terms of one particle, Um, 221 00:11:30,520 --> 00:11:32,280 Speaker 1: you know that, I would say, then we would want 222 00:11:32,280 --> 00:11:33,840 Speaker 1: to tell a story, right, We want to tell a 223 00:11:33,840 --> 00:11:36,680 Speaker 1: story about what that means about the universe and why 224 00:11:36,720 --> 00:11:38,680 Speaker 1: the universe? Why is the universe this way and not 225 00:11:38,760 --> 00:11:40,600 Speaker 1: the other way? First we have to figure out what 226 00:11:40,760 --> 00:11:42,720 Speaker 1: way is the universe, and then we want to know, 227 00:11:42,800 --> 00:11:45,800 Speaker 1: like why that way. In the end, we're still telling 228 00:11:45,880 --> 00:11:48,640 Speaker 1: stories to ourselves about how the universe came to be 229 00:11:48,760 --> 00:11:50,760 Speaker 1: and what it means and how we should live our lives. 230 00:11:51,000 --> 00:11:54,199 Speaker 1: So it's a very human endeavor. Well, certainly, I mean, 231 00:11:54,240 --> 00:11:57,480 Speaker 1: we we call it matter, and we know about anti matter, 232 00:11:57,800 --> 00:12:01,800 Speaker 1: but we chose the optimist route right when we describe, 233 00:12:01,840 --> 00:12:04,680 Speaker 1: when we describe these things that are antithetical to one another, 234 00:12:04,760 --> 00:12:08,160 Speaker 1: and they they annihilate one another when they come into contact. 235 00:12:08,160 --> 00:12:10,640 Speaker 1: And for some reason that we don't fully understand, we 236 00:12:10,679 --> 00:12:14,160 Speaker 1: had slightly more matter than we had antimatter, and therefore 237 00:12:14,200 --> 00:12:17,600 Speaker 1: we've got stuff. I mean, if we had been pessimists, 238 00:12:17,600 --> 00:12:20,560 Speaker 1: we would call the stuff we have the antimatter, right, 239 00:12:21,360 --> 00:12:25,080 Speaker 1: So clearly there's a narrative issue there. So here, seriously, 240 00:12:25,120 --> 00:12:27,360 Speaker 1: here's the question. Then the question is do you think 241 00:12:27,400 --> 00:12:30,240 Speaker 1: if we met an alien species of physicists, do you 242 00:12:30,240 --> 00:12:33,040 Speaker 1: think they would be asking the same questions or would 243 00:12:33,040 --> 00:12:35,520 Speaker 1: they be satisfied with our answers, or do you think 244 00:12:35,520 --> 00:12:38,920 Speaker 1: the kind of questions we're asking are inherently human in 245 00:12:38,960 --> 00:12:42,920 Speaker 1: some way that we don't even understand? What an excellent question. Now, obviously, 246 00:12:42,960 --> 00:12:45,080 Speaker 1: from the scientific perspective, I have to tell you that 247 00:12:45,120 --> 00:12:47,520 Speaker 1: I have a very small sample size of intelligent life 248 00:12:47,559 --> 00:12:51,840 Speaker 1: forms that I can work from. I only have the one. Really, you, 249 00:12:51,840 --> 00:12:53,840 Speaker 1: you mean you're the only intelligent life form, you know, 250 00:12:53,920 --> 00:12:57,400 Speaker 1: I mean of entire I'm talking about entire species. I 251 00:12:57,440 --> 00:13:00,240 Speaker 1: guess I'm not not only. I mean, I could get 252 00:13:00,280 --> 00:13:04,000 Speaker 1: super nihilistic and and and very egotistical and say, well, 253 00:13:04,080 --> 00:13:06,880 Speaker 1: I can only experience my own experience, and therefore I 254 00:13:06,880 --> 00:13:12,319 Speaker 1: know I'm intelligence. But I'm just granting everybody else that consideration. Um, 255 00:13:12,400 --> 00:13:18,320 Speaker 1: that's very this This gets into philosophy and then, which 256 00:13:18,320 --> 00:13:21,280 Speaker 1: I also fascinated by. But I'm a pragmatist, so eventually 257 00:13:21,320 --> 00:13:25,280 Speaker 1: I get very irritated. Um, that's an excellent question, and 258 00:13:25,280 --> 00:13:29,520 Speaker 1: and honestly, the it's one that I haven't given a 259 00:13:29,520 --> 00:13:34,000 Speaker 1: lot of consideration too, largely because I have accepted the fact, 260 00:13:34,280 --> 00:13:38,480 Speaker 1: or at least accepted the notion that any sufficiently intelligent 261 00:13:39,080 --> 00:13:43,360 Speaker 1: species that may exist somewhere else could be so very 262 00:13:43,440 --> 00:13:47,720 Speaker 1: different from what we experience that that the word alien 263 00:13:47,880 --> 00:13:52,839 Speaker 1: only begins to describe how we would uh define such 264 00:13:53,080 --> 00:13:57,440 Speaker 1: a species, And that perhaps their approach to understanding and 265 00:13:57,520 --> 00:14:00,920 Speaker 1: explaining the universe to themselves would be very different. But 266 00:14:01,440 --> 00:14:05,600 Speaker 1: it seems like it would follow a similar pattern but 267 00:14:05,679 --> 00:14:08,240 Speaker 1: I say that only because that's what that's what has 268 00:14:08,280 --> 00:14:11,600 Speaker 1: happened here. I don't have anywhere else to draw any 269 00:14:11,600 --> 00:14:15,680 Speaker 1: conclusions from. So, um, it's so hard to imagine outside 270 00:14:15,720 --> 00:14:18,520 Speaker 1: of your experience, right, It's it's very, very difficult. Yet 271 00:14:18,559 --> 00:14:21,280 Speaker 1: in science, when we discover something new, we're always describing 272 00:14:21,280 --> 00:14:24,000 Speaker 1: it in terms of the things we know. Like we 273 00:14:24,040 --> 00:14:27,600 Speaker 1: want to know what is light? Is it a little particle? 274 00:14:27,800 --> 00:14:30,120 Speaker 1: Is it a little way? Because of the things we know? Right, 275 00:14:30,120 --> 00:14:33,000 Speaker 1: when we find something that's totally new and different, we 276 00:14:33,000 --> 00:14:35,040 Speaker 1: don't even really have the words to describe it. So 277 00:14:35,280 --> 00:14:37,920 Speaker 1: imagining what it's like to be an alien scientist, I 278 00:14:37,960 --> 00:14:40,480 Speaker 1: think it's an impossible question. So yeah, and that's that's 279 00:14:40,480 --> 00:14:42,520 Speaker 1: why I posed it to you. It's why it's why 280 00:14:42,720 --> 00:14:47,000 Speaker 1: I while I find science fiction endlessly entertaining, I love 281 00:14:47,080 --> 00:14:51,320 Speaker 1: science fiction. I also always I roll my eyes a 282 00:14:51,400 --> 00:14:54,000 Speaker 1: little bit when I see the star Trek approach of 283 00:14:54,120 --> 00:14:57,320 Speaker 1: every alien race is a humanoid with slightly different bumps 284 00:14:57,320 --> 00:15:01,600 Speaker 1: on their head, and they speak English the same way. Yeah, 285 00:15:01,680 --> 00:15:05,320 Speaker 1: the Universal Translator has no problem picking up what their 286 00:15:05,320 --> 00:15:07,520 Speaker 1: speech patterns are. So that like, even when you use 287 00:15:07,560 --> 00:15:11,440 Speaker 1: the Universal translator, uh, the you know, d o Sex 288 00:15:11,520 --> 00:15:14,000 Speaker 1: Macina coming in and saying, oh, yeah, this is going 289 00:15:14,040 --> 00:15:17,440 Speaker 1: to translate everything magically. You think you kind of need 290 00:15:17,480 --> 00:15:20,720 Speaker 1: a sample size, don't you, before you really get a 291 00:15:20,760 --> 00:15:22,640 Speaker 1: grasp on it. But I mean, we have a hard 292 00:15:22,720 --> 00:15:26,160 Speaker 1: enough trouble, hard enough time even on Earth sometimes understanding 293 00:15:26,320 --> 00:15:29,840 Speaker 1: human cultures from around the globe, you know, so understanding 294 00:15:29,880 --> 00:15:32,440 Speaker 1: how to interact with aliens. I think it's gonna be helpless. 295 00:15:32,440 --> 00:15:34,760 Speaker 1: Like if we ever heard a message from aliens, and 296 00:15:35,280 --> 00:15:37,440 Speaker 1: you know, even decoding it would be a huge problem 297 00:15:37,480 --> 00:15:39,960 Speaker 1: if you could even get past that. I have challenges 298 00:15:40,160 --> 00:15:42,840 Speaker 1: understanding some of my relatives, and we all speak the 299 00:15:42,880 --> 00:15:45,920 Speaker 1: same language and arguably come from the same culture. Are 300 00:15:45,960 --> 00:15:47,320 Speaker 1: you sure they all come from Earth? I mean, that 301 00:15:47,400 --> 00:15:49,800 Speaker 1: might be an explanation. I got an uncle that's questionable, 302 00:15:49,840 --> 00:15:51,760 Speaker 1: but pretty much everyone else I got a pretty good 303 00:15:51,800 --> 00:15:55,840 Speaker 1: handle on. This is This is great. This is gonna 304 00:15:55,840 --> 00:15:57,920 Speaker 1: be an eighteen partner. Guys, I'm just gonna sit here 305 00:15:57,960 --> 00:16:02,440 Speaker 1: and and and and monopolized annuals. Time for the rest 306 00:16:02,440 --> 00:16:05,200 Speaker 1: of you. Want to talk about the large Adran Collider 307 00:16:05,320 --> 00:16:08,880 Speaker 1: rather than philosophy of alien civilization, I wouldn't say. Rather, 308 00:16:09,760 --> 00:16:13,400 Speaker 1: I'll just say that my questions were about, well, you know, 309 00:16:13,440 --> 00:16:17,160 Speaker 1: there's one topic which connects them um, which is the 310 00:16:17,160 --> 00:16:20,480 Speaker 1: one way we might discover an alien civilization is by 311 00:16:20,720 --> 00:16:26,120 Speaker 1: first detecting their particle physicists. I have not heard this. 312 00:16:26,320 --> 00:16:29,560 Speaker 1: It might be if somebody's if aliens are building like 313 00:16:29,840 --> 00:16:32,920 Speaker 1: enormous particle colliders like the size of a solar system, 314 00:16:32,960 --> 00:16:36,000 Speaker 1: and we might eventually like sweep through the essentially the 315 00:16:36,040 --> 00:16:40,240 Speaker 1: pollution from that part from that particle accelerator and discover 316 00:16:40,360 --> 00:16:42,280 Speaker 1: them in that way. That would be pretty crazy way 317 00:16:42,520 --> 00:16:44,600 Speaker 1: to find an alien species, But that would be awesome 318 00:16:44,600 --> 00:16:46,440 Speaker 1: because it would it would tell us that, hey, look, 319 00:16:46,720 --> 00:16:48,840 Speaker 1: particle physics is not just a human thing, it's a 320 00:16:48,960 --> 00:16:51,760 Speaker 1: universal thing. Everyone wants to know what the universe is 321 00:16:51,800 --> 00:16:54,080 Speaker 1: made out of, and everyone's figuring it out by smashing 322 00:16:54,080 --> 00:16:57,160 Speaker 1: stuff together. So that would be pretty exciting discovery. It 323 00:16:57,200 --> 00:17:00,240 Speaker 1: is interesting I had not heard about that particul are 324 00:17:00,240 --> 00:17:03,000 Speaker 1: a kind of an idea. I've heard of, of course, 325 00:17:03,360 --> 00:17:07,359 Speaker 1: enormous constructs that could especially when you talk about things 326 00:17:07,400 --> 00:17:09,320 Speaker 1: like the Kardashov scale and you're thinking about like the 327 00:17:09,400 --> 00:17:12,640 Speaker 1: dice and sphere and that kind of stuff. These hypothetical 328 00:17:13,200 --> 00:17:16,800 Speaker 1: UM machines that would need to exist in order to 329 00:17:16,800 --> 00:17:20,720 Speaker 1: to take advantage of, say, an entire solar system's energy output, 330 00:17:21,320 --> 00:17:23,520 Speaker 1: which would be necessary to reach those higher levels of 331 00:17:23,520 --> 00:17:27,440 Speaker 1: civilization that we've heard about. But I hadn't heard about. 332 00:17:27,600 --> 00:17:31,359 Speaker 1: I hadn't thought about a particle accelery the size of 333 00:17:31,359 --> 00:17:33,919 Speaker 1: a solar system. To be perfectly honest, the large Hadron 334 00:17:33,920 --> 00:17:36,480 Speaker 1: collider is is a big enough beast for me to 335 00:17:36,480 --> 00:17:39,240 Speaker 1: try and get my mind wrapped around. I mean, they're 336 00:17:39,240 --> 00:17:42,280 Speaker 1: talking about pretty expensive. So yeah, the solar system sized 337 00:17:42,320 --> 00:17:45,160 Speaker 1: collider is going to take another level of civilization before 338 00:17:45,160 --> 00:17:47,800 Speaker 1: we can afford that kind of equipment. Yeah. Hey, guys, 339 00:17:47,840 --> 00:17:51,360 Speaker 1: this is Jonathan from the Future just breaking into Jonathan 340 00:17:51,400 --> 00:17:53,600 Speaker 1: from the past to explain that we're going to take 341 00:17:53,600 --> 00:17:56,119 Speaker 1: a quick break with our conversation with Daniel Whiteson to 342 00:17:56,320 --> 00:18:09,080 Speaker 1: thank our sponsor. So getting to the large Hadron Collider. Uh, 343 00:18:09,320 --> 00:18:11,680 Speaker 1: that would you know? And CERN as well. A lot 344 00:18:11,680 --> 00:18:14,760 Speaker 1: of people think of of CERN is just because the 345 00:18:14,840 --> 00:18:17,400 Speaker 1: Large Hadron Collider got so much press a few years 346 00:18:17,400 --> 00:18:19,680 Speaker 1: ago when it was when they were preparing to bring 347 00:18:19,680 --> 00:18:21,479 Speaker 1: it up online and they were starting to stub up 348 00:18:21,480 --> 00:18:23,399 Speaker 1: the energy levels. I think a lot of people just 349 00:18:23,440 --> 00:18:27,119 Speaker 1: associated those two as being. Uh, the only real like 350 00:18:27,200 --> 00:18:29,480 Speaker 1: they CERN is just that's the agency to oversee the 351 00:18:29,560 --> 00:18:32,840 Speaker 1: Large Hadron Collider. I like to remind people that CERN 352 00:18:33,000 --> 00:18:37,840 Speaker 1: is also the organization where because CERN exists, we have 353 00:18:37,920 --> 00:18:40,960 Speaker 1: a worldwide web. I mean the web started from Tim 354 00:18:40,960 --> 00:18:44,920 Speaker 1: berners Lee, who was working for CERTAIN at the time. So, uh, 355 00:18:45,160 --> 00:18:47,600 Speaker 1: I like to remind people that it's beyond that. But 356 00:18:47,680 --> 00:18:50,920 Speaker 1: let's talk a bit so. So CERN is a European agency. 357 00:18:51,520 --> 00:18:56,160 Speaker 1: That UM is a scientifically oriented agency looking into things 358 00:18:56,200 --> 00:18:59,720 Speaker 1: like these, these high energy reactions. And the large Hadron 359 00:18:59,760 --> 00:19:03,399 Speaker 1: Collider is a particle accelerator. Uh, can I give us 360 00:19:03,400 --> 00:19:07,840 Speaker 1: an overview of what the LHC is for for someone 361 00:19:07,880 --> 00:19:11,240 Speaker 1: who has heard the term but they don't really get 362 00:19:11,359 --> 00:19:15,880 Speaker 1: they don't grock it entirely, alright, Sure, UM, the large 363 00:19:15,920 --> 00:19:18,760 Speaker 1: hay Droun Collider. The basic idea is, let's figure out 364 00:19:18,800 --> 00:19:23,720 Speaker 1: what's inside matter. Let's figure out what's inside matter, and 365 00:19:23,800 --> 00:19:27,000 Speaker 1: let's do that by smashing particles together. So what you 366 00:19:27,040 --> 00:19:30,040 Speaker 1: do with the large Hadron collider the word large it 367 00:19:30,080 --> 00:19:33,160 Speaker 1: obviously just means it's really big. Hadron is a kind 368 00:19:33,200 --> 00:19:36,119 Speaker 1: of particle, and proton is the example of it. So 369 00:19:36,200 --> 00:19:39,240 Speaker 1: you could also call it the Large Proton Collider. UM. 370 00:19:39,280 --> 00:19:42,560 Speaker 1: And we take protons, which are essentially just the nucleus 371 00:19:42,560 --> 00:19:44,879 Speaker 1: of hydrogen. So you start with hydrogen gas which is 372 00:19:44,880 --> 00:19:48,280 Speaker 1: easy to get, heat it up, so the electrons boil off, 373 00:19:48,320 --> 00:19:50,359 Speaker 1: and you left with just the nucleus, which is protons. 374 00:19:51,040 --> 00:19:52,880 Speaker 1: And what we do is we give those protons a kick. 375 00:19:53,200 --> 00:19:56,320 Speaker 1: We use electromagnetic waves to push them, and we push 376 00:19:56,359 --> 00:19:59,160 Speaker 1: them faster and faster and faster and faster until they're 377 00:19:59,160 --> 00:20:03,080 Speaker 1: going about in ninety niono the speed of light. And 378 00:20:03,080 --> 00:20:05,679 Speaker 1: then we smash them into each other. And the idea is, 379 00:20:05,960 --> 00:20:09,000 Speaker 1: see what comes out, See what kind of weird mysterious 380 00:20:09,080 --> 00:20:11,800 Speaker 1: quantum mechanical magic happens to give you new kinds of 381 00:20:11,840 --> 00:20:15,040 Speaker 1: matter and new weird particles. Um. But as you said, 382 00:20:15,160 --> 00:20:18,080 Speaker 1: the Large Hadron Collider is so to the flagship property 383 00:20:18,320 --> 00:20:22,280 Speaker 1: flagship Experimenter, but certain is much broader than that. It's 384 00:20:22,320 --> 00:20:25,600 Speaker 1: a it's a European organization, but it's also international. I mean, 385 00:20:25,640 --> 00:20:28,080 Speaker 1: I've I've been there many summers and you sit at 386 00:20:28,080 --> 00:20:30,640 Speaker 1: a table at the restaurant and there's people speaking all 387 00:20:30,680 --> 00:20:32,800 Speaker 1: sorts of languages. You know, this Italian at this table 388 00:20:32,840 --> 00:20:35,280 Speaker 1: and Russian at that table and tie at the other table, 389 00:20:35,320 --> 00:20:38,440 Speaker 1: and Chinese over here, and you meet people from hundreds 390 00:20:38,440 --> 00:20:41,200 Speaker 1: of countries, well not hundreds, but more than a hundred countries, 391 00:20:41,600 --> 00:20:44,399 Speaker 1: and it's a it's a super international place, which is 392 00:20:44,440 --> 00:20:46,520 Speaker 1: really wonderful, and right now it really is the center 393 00:20:46,560 --> 00:20:49,000 Speaker 1: of the world and the Solar System, and you know, 394 00:20:49,080 --> 00:20:52,840 Speaker 1: maybe the galaxy in terms of particle physics. But we 395 00:20:52,880 --> 00:20:55,720 Speaker 1: do more than just the Large Hadron Collider. We also 396 00:20:55,760 --> 00:20:58,720 Speaker 1: have experiments studying the mysterious particle called the new trino. 397 00:20:59,320 --> 00:21:01,879 Speaker 1: Neutrinos are produced by the Sun and the surface of 398 00:21:01,880 --> 00:21:04,600 Speaker 1: the Earth is just bombarded with neutrinos, but they're mostly 399 00:21:04,640 --> 00:21:07,239 Speaker 1: invisible to us. They don't interact with us, but they 400 00:21:07,280 --> 00:21:09,960 Speaker 1: have a lot of really interesting properties that we don't understand. 401 00:21:10,280 --> 00:21:12,480 Speaker 1: So CERTAIN does a lot of neutrino physics as well. 402 00:21:12,920 --> 00:21:15,640 Speaker 1: Um they do cosmic ray physics, looking at weird particles 403 00:21:15,640 --> 00:21:18,760 Speaker 1: from space. They do a big variety of particle physics. 404 00:21:18,960 --> 00:21:21,440 Speaker 1: And CERTAIN has played a big role in politics as well. 405 00:21:21,680 --> 00:21:23,560 Speaker 1: I don't know if you're aware, but Certain was founded 406 00:21:23,800 --> 00:21:26,920 Speaker 1: after World War Two, the idea being let's get all 407 00:21:26,920 --> 00:21:30,280 Speaker 1: the scientists of Europe to work together on projects rather 408 00:21:30,320 --> 00:21:32,360 Speaker 1: than hiding in their own labs and hating each other 409 00:21:32,760 --> 00:21:35,920 Speaker 1: and sort of like using science as this common human bridge, 410 00:21:36,000 --> 00:21:38,720 Speaker 1: like let's get connected. Let's not have our own like 411 00:21:38,920 --> 00:21:42,040 Speaker 1: individual weapons projects. Let's find something we can all work 412 00:21:42,040 --> 00:21:44,280 Speaker 1: together on in a positive way. And I think it's 413 00:21:44,280 --> 00:21:47,679 Speaker 1: really credited with tying European science together in a way 414 00:21:47,720 --> 00:21:50,440 Speaker 1: that's made it more effective. And you know, building harmonies 415 00:21:50,440 --> 00:21:53,600 Speaker 1: between nations is also good, and I know that personally 416 00:21:53,640 --> 00:21:55,720 Speaker 1: at certain I've eaten a lot of weird food from 417 00:21:55,720 --> 00:21:58,960 Speaker 1: different countries and that's helped me understand, you know, um, 418 00:21:59,320 --> 00:22:01,359 Speaker 1: why the Belgians is like horse meat and why the 419 00:22:01,440 --> 00:22:04,400 Speaker 1: Chinese eat these weird things. And it's a fun cultural 420 00:22:04,400 --> 00:22:08,440 Speaker 1: experience as well as scientific. Well yeah, and and uh, 421 00:22:08,560 --> 00:22:10,600 Speaker 1: you know, getting into some of the fun stuff. Well 422 00:22:10,600 --> 00:22:13,560 Speaker 1: we'll talk about later. But I love reading about, uh, 423 00:22:14,080 --> 00:22:17,480 Speaker 1: things that remind us that scientists are also human. I 424 00:22:17,520 --> 00:22:20,119 Speaker 1: mean it's it's easy to kind of forget from a 425 00:22:20,440 --> 00:22:23,720 Speaker 1: layman perspective. You you hear about science, and you hear 426 00:22:23,720 --> 00:22:29,280 Speaker 1: about scientists, and it tends to almost be another For 427 00:22:29,520 --> 00:22:33,160 Speaker 1: people who are not necessarily involved in science, or are 428 00:22:33,200 --> 00:22:36,080 Speaker 1: not they don't work with scientists, and so they start 429 00:22:36,160 --> 00:22:39,320 Speaker 1: to think of that as their own category of living thing. 430 00:22:39,640 --> 00:22:44,240 Speaker 1: There's a scientist kind of like doctors. There's doctors, they're scientists, 431 00:22:44,320 --> 00:22:46,760 Speaker 1: and uh, it's like that time that you meet your 432 00:22:46,760 --> 00:22:50,840 Speaker 1: middle school science teacher at the grocery store buying cereal 433 00:22:50,880 --> 00:22:53,520 Speaker 1: and you're like, what you know, breakfast, this is not. 434 00:22:54,680 --> 00:22:59,280 Speaker 1: This is not. Scientists have families and ambitions and disappointments 435 00:22:59,359 --> 00:23:02,240 Speaker 1: and and rock rock groups, as it turns out, in 436 00:23:02,320 --> 00:23:05,000 Speaker 1: rock groups, and you know, ankle injuries and all the 437 00:23:05,040 --> 00:23:09,000 Speaker 1: same sort of things that people have. Absolutely, so what 438 00:23:09,200 --> 00:23:14,760 Speaker 1: experiment at the LHC did you are you working with? Specifically, 439 00:23:14,800 --> 00:23:18,520 Speaker 1: they're different because they're different ones that are associated with 440 00:23:18,600 --> 00:23:21,520 Speaker 1: different points along the LHC. As I understand it, where 441 00:23:21,520 --> 00:23:24,680 Speaker 1: it's different essentially collision points that are looking at very 442 00:23:24,720 --> 00:23:30,360 Speaker 1: specific uh, byproducts of these high energy collisions. That's right. 443 00:23:30,400 --> 00:23:33,720 Speaker 1: So we have two beams of protons um, one going 444 00:23:33,840 --> 00:23:35,520 Speaker 1: one way around the circle and the other going the 445 00:23:35,560 --> 00:23:38,160 Speaker 1: other way. And if somebody out there is wondering, well, 446 00:23:38,160 --> 00:23:40,440 Speaker 1: why is it a circle? The reason is the circle 447 00:23:40,520 --> 00:23:42,560 Speaker 1: is that it takes a while to get protons up 448 00:23:42,600 --> 00:23:44,760 Speaker 1: to high enough speed. That's what we want to do, 449 00:23:44,800 --> 00:23:47,720 Speaker 1: is we want to reuse those little boosters. The circle 450 00:23:47,760 --> 00:23:50,480 Speaker 1: is essentially a string of little boosters. Each one gives 451 00:23:50,520 --> 00:23:52,480 Speaker 1: a little kick and gets it going faster and faster. 452 00:23:53,160 --> 00:23:55,679 Speaker 1: And so if you can spin it around multiple times, 453 00:23:55,680 --> 00:23:57,960 Speaker 1: that you can get it going faster and faster. It's 454 00:23:57,960 --> 00:24:00,119 Speaker 1: like when your kids on the merry go round or 455 00:24:00,160 --> 00:24:02,200 Speaker 1: nothing merry around. What is that thing called the at 456 00:24:02,200 --> 00:24:04,640 Speaker 1: the playground that spins around? Yeah, I know what you're 457 00:24:04,640 --> 00:24:07,760 Speaker 1: talking about. I honestly don't know the name of that either. 458 00:24:07,960 --> 00:24:12,040 Speaker 1: The vominator the vominator um uh and and you put 459 00:24:12,080 --> 00:24:13,600 Speaker 1: them on there and you spend it, you keep pushing, 460 00:24:13,600 --> 00:24:15,440 Speaker 1: it goes faster and faster. So that's why it goes 461 00:24:15,480 --> 00:24:18,000 Speaker 1: in a circle. Um. And in order to bend them 462 00:24:18,000 --> 00:24:20,439 Speaker 1: in a circle, we have these really strong magnets. So 463 00:24:20,520 --> 00:24:22,800 Speaker 1: the way the collider works is it's a kick to 464 00:24:22,800 --> 00:24:25,199 Speaker 1: make it faster and then a magnet to bend it 465 00:24:25,359 --> 00:24:28,000 Speaker 1: to go in a circle. And because we want to 466 00:24:28,040 --> 00:24:30,359 Speaker 1: collide the protons, we actually have two of these. We 467 00:24:30,400 --> 00:24:32,840 Speaker 1: have one going one way and other than protons going 468 00:24:32,920 --> 00:24:36,360 Speaker 1: the other way, and so four places around the ring 469 00:24:36,760 --> 00:24:39,840 Speaker 1: we cross those beams, right, we try to collide them. 470 00:24:40,240 --> 00:24:42,520 Speaker 1: And and also it's not individual proton. It's not like 471 00:24:42,560 --> 00:24:45,320 Speaker 1: we put one proton in the in one beam and 472 00:24:45,359 --> 00:24:47,199 Speaker 1: another proton the other beam, and we zoomed around. We 473 00:24:47,200 --> 00:24:50,080 Speaker 1: smashed one proton. It's really hard to get protons to 474 00:24:50,160 --> 00:24:52,959 Speaker 1: hit each other because they're so small um, and so 475 00:24:53,000 --> 00:24:55,720 Speaker 1: we actually have like a little gas of protons. It's 476 00:24:55,720 --> 00:24:57,960 Speaker 1: a we call it a technical term, is a bunch 477 00:24:58,000 --> 00:25:01,439 Speaker 1: of protons, and it's in tend to some number of 478 00:25:01,440 --> 00:25:05,080 Speaker 1: protons that we passed through another gas of protons hoping 479 00:25:05,119 --> 00:25:08,400 Speaker 1: to get some collisions. And so there's four places around 480 00:25:08,400 --> 00:25:11,440 Speaker 1: the ring that this happens, and each one is surrounded 481 00:25:11,640 --> 00:25:15,480 Speaker 1: by a massive set of detectors um to observe what happens. 482 00:25:15,480 --> 00:25:18,040 Speaker 1: Think of it like a really big digital camera. And 483 00:25:18,160 --> 00:25:20,080 Speaker 1: I work on one of those. And the name of 484 00:25:20,080 --> 00:25:24,040 Speaker 1: the detector is the Atlas detector, which has like which 485 00:25:24,080 --> 00:25:27,200 Speaker 1: sets the record from maybe the worst scientific acronym ever, 486 00:25:27,960 --> 00:25:30,480 Speaker 1: because it has an acronym inside. I think Atlas stands 487 00:25:30,520 --> 00:25:38,160 Speaker 1: for a large toroidal LHC apparatus. It's the most tortured 488 00:25:38,160 --> 00:25:41,600 Speaker 1: acronym ever. Anyway, Atlas surrounds one of the collision points 489 00:25:41,640 --> 00:25:44,800 Speaker 1: and we smash the protons together there and that's where 490 00:25:44,800 --> 00:25:47,520 Speaker 1: the magic happens. And you might be thinking, uh, you know, 491 00:25:47,560 --> 00:25:49,840 Speaker 1: if you smash protons together, all you can learn about 492 00:25:49,880 --> 00:25:52,040 Speaker 1: is what's inside protons, right the way, if you take 493 00:25:52,080 --> 00:25:55,120 Speaker 1: your blender apart, you can learn about what's inside blenders. 494 00:25:55,160 --> 00:25:57,600 Speaker 1: That's true, and we can learn about what's inside blenders, 495 00:25:57,640 --> 00:26:00,800 Speaker 1: but as what's inside protons um. But we can also 496 00:26:00,920 --> 00:26:03,679 Speaker 1: do something else because of the magic of quantum mechanics. 497 00:26:04,000 --> 00:26:07,280 Speaker 1: What happens when you collide a proton and another proton 498 00:26:07,720 --> 00:26:10,439 Speaker 1: is that the particles inside them interact. So inside a 499 00:26:10,440 --> 00:26:13,679 Speaker 1: proton we have quirks of quirks and down corks, and 500 00:26:13,760 --> 00:26:16,760 Speaker 1: those quirks can interact and they can actually annihilate, which 501 00:26:16,800 --> 00:26:19,760 Speaker 1: means that they convert from mass from little bits of 502 00:26:19,800 --> 00:26:24,480 Speaker 1: stuff flying through the particle collider into energy. Okay, so 503 00:26:24,560 --> 00:26:27,520 Speaker 1: the particles are gone, the stuff that made them up 504 00:26:27,600 --> 00:26:30,640 Speaker 1: is destroyed. It's turned into energy, and then that energy 505 00:26:31,000 --> 00:26:33,840 Speaker 1: gets turned back into mass because a little blob of 506 00:26:33,920 --> 00:26:36,240 Speaker 1: energy is very unstable, doesn't like they hang out very long, 507 00:26:36,840 --> 00:26:39,520 Speaker 1: and so it turns back into mass and it doesn't 508 00:26:39,520 --> 00:26:41,920 Speaker 1: have to turn back into the same kind of stuff 509 00:26:41,960 --> 00:26:44,680 Speaker 1: that it's started from. So you can turn for example, 510 00:26:44,680 --> 00:26:47,280 Speaker 1: two up corks. You can annihilate them together, turn them 511 00:26:47,280 --> 00:26:49,120 Speaker 1: into a ball of energy, and then they can turn 512 00:26:49,160 --> 00:26:53,720 Speaker 1: into muans or electrons or other weird kinds of particles, 513 00:26:54,160 --> 00:26:56,280 Speaker 1: and it's not required that it's made of the same 514 00:26:56,280 --> 00:26:59,359 Speaker 1: stuff because the stuff has disappeared, it's been annihilated. So 515 00:26:59,560 --> 00:27:02,720 Speaker 1: it really is like modern day alchemy. You know, we're 516 00:27:02,760 --> 00:27:06,320 Speaker 1: turning one kind of stuff into another kind of stuff, 517 00:27:06,960 --> 00:27:10,359 Speaker 1: and that's magical because it means we can create any 518 00:27:10,440 --> 00:27:13,399 Speaker 1: kind of stuff that's sort of on the universe's menu. 519 00:27:13,800 --> 00:27:16,240 Speaker 1: We don't have to know it's there in advance. We 520 00:27:16,359 --> 00:27:20,160 Speaker 1: just pour enough energy into the collisions and eventually all 521 00:27:20,160 --> 00:27:23,520 Speaker 1: the kinds of stuff will pop out. So it's it's 522 00:27:23,560 --> 00:27:26,680 Speaker 1: really like an exploration machine. It's like saying, what's out there, 523 00:27:26,720 --> 00:27:29,680 Speaker 1: what's on Nature's list of particles? What can we make 524 00:27:29,720 --> 00:27:32,479 Speaker 1: if we put enough energy into the collider. And so 525 00:27:32,520 --> 00:27:35,080 Speaker 1: that's how we smash protons together to try to figure 526 00:27:35,080 --> 00:27:38,040 Speaker 1: out what is the list of particles that the universe 527 00:27:38,119 --> 00:27:41,080 Speaker 1: has on the list of sort of allowed states. And 528 00:27:41,119 --> 00:27:43,119 Speaker 1: that's that's what we're doing to try to get inside 529 00:27:43,119 --> 00:27:45,719 Speaker 1: into this question of what is the universe made out of? 530 00:27:45,920 --> 00:27:50,480 Speaker 1: That's incredibly cool, like I've never heard it described that way. 531 00:27:50,560 --> 00:27:55,119 Speaker 1: So too, the thought of of smashing these protons together 532 00:27:55,119 --> 00:27:58,040 Speaker 1: at incredibly high energies and then you end up as 533 00:27:58,080 --> 00:28:02,280 Speaker 1: part of that uh at almost like the proto energy 534 00:28:02,400 --> 00:28:05,520 Speaker 1: that can convert into various different types of things based 535 00:28:05,560 --> 00:28:09,960 Speaker 1: on possibly criteria that we don't fully understand, I mean obviously, 536 00:28:10,720 --> 00:28:12,280 Speaker 1: And those are the laws we're trying to figure out, 537 00:28:12,320 --> 00:28:15,760 Speaker 1: you know, we're trying to write down mathematical equations that 538 00:28:15,920 --> 00:28:18,719 Speaker 1: predict how often you'll see this kind of particle, how 539 00:28:18,760 --> 00:28:21,120 Speaker 1: often you see that kind of particle, And the kinds 540 00:28:21,119 --> 00:28:23,800 Speaker 1: of particles that we've studied, you know, electrons and muance whatever. 541 00:28:23,960 --> 00:28:26,560 Speaker 1: We understand how those are made, and we can calculate 542 00:28:26,760 --> 00:28:30,400 Speaker 1: very precisely how often we should see them and uh 543 00:28:30,400 --> 00:28:32,320 Speaker 1: and what energies, and so that's the kind of thing 544 00:28:32,400 --> 00:28:34,720 Speaker 1: we study. We we understand in pretty and pretty good 545 00:28:34,720 --> 00:28:37,800 Speaker 1: detail why some particles are made and when and how often. 546 00:28:38,040 --> 00:28:40,600 Speaker 1: What we're looking for is the weird stuff, the stuff 547 00:28:40,640 --> 00:28:43,680 Speaker 1: we haven't predicted, or the stuff we hadn't anticipated, or 548 00:28:43,920 --> 00:28:45,960 Speaker 1: you know, the things that people have predicted but we 549 00:28:46,000 --> 00:28:48,520 Speaker 1: haven't seen yet. And those things tend to be more rare, 550 00:28:48,960 --> 00:28:51,520 Speaker 1: which is why we smash the particles together so often. 551 00:28:51,880 --> 00:28:55,680 Speaker 1: We do it every twenty five nanoseconds, all day, all 552 00:28:55,800 --> 00:28:58,320 Speaker 1: year long. And the reason is most of the stuff 553 00:28:58,360 --> 00:29:02,160 Speaker 1: that happens is boring. We've seen it before. Occasionally, very rarely, 554 00:29:02,280 --> 00:29:04,800 Speaker 1: something weird will happen and that will give us a 555 00:29:04,840 --> 00:29:08,840 Speaker 1: clue about maybe a new kind of rare particle. So 556 00:29:09,080 --> 00:29:13,840 Speaker 1: I imagine if you're doing this that frequently with that 557 00:29:13,920 --> 00:29:17,720 Speaker 1: many protons, knowing not that all of them are are colliding, 558 00:29:17,720 --> 00:29:20,160 Speaker 1: but still a good amount of them are UM and 559 00:29:20,280 --> 00:29:23,720 Speaker 1: you have these four different points where they're all gathering 560 00:29:23,840 --> 00:29:26,880 Speaker 1: data that you're you're getting getting a few zeros and 561 00:29:26,960 --> 00:29:29,080 Speaker 1: ones out of there. There's a lot I'm guessing a 562 00:29:29,080 --> 00:29:33,520 Speaker 1: lot of information gets generated all the time through these experiments. 563 00:29:34,080 --> 00:29:37,200 Speaker 1: It's a it's a tidal wave of data. Every time 564 00:29:37,200 --> 00:29:39,880 Speaker 1: we have a collision, we read out the whole detector, 565 00:29:39,920 --> 00:29:43,240 Speaker 1: which has a hundred million different detector channels. So it's 566 00:29:43,240 --> 00:29:47,040 Speaker 1: a massive basically digital image of the detector every every 567 00:29:47,080 --> 00:29:50,960 Speaker 1: every twenty five nanoseconds UM and so that's pretty it's 568 00:29:50,960 --> 00:29:54,000 Speaker 1: a pretty large volume of data UM and we it's 569 00:29:54,040 --> 00:29:56,760 Speaker 1: so big that we can't even save it all, right. 570 00:29:56,800 --> 00:29:59,280 Speaker 1: We if we saved it all, it would take huge 571 00:29:59,280 --> 00:30:01,280 Speaker 1: amount of resource, says, and we wouldn't have no time 572 00:30:01,320 --> 00:30:03,640 Speaker 1: to go through it. So what we and most of 573 00:30:03,640 --> 00:30:07,160 Speaker 1: it is not very interesting. Of what happens is just 574 00:30:07,200 --> 00:30:09,360 Speaker 1: like two protons come in, they kind of bounce off 575 00:30:09,400 --> 00:30:12,200 Speaker 1: each other, two protons come out. You know, it's rare 576 00:30:12,240 --> 00:30:14,400 Speaker 1: that you actually have them, like a deep collision that 577 00:30:14,680 --> 00:30:17,760 Speaker 1: interacts with the particles inside that makes something weird. And 578 00:30:17,800 --> 00:30:19,840 Speaker 1: so what we do is we have this system we 579 00:30:19,880 --> 00:30:22,280 Speaker 1: call it the trigger, that makes a keep or kill 580 00:30:22,360 --> 00:30:25,480 Speaker 1: decision on the fly, and it says was it interesting 581 00:30:25,560 --> 00:30:28,440 Speaker 1: enough to save? If so, then shunt it down the 582 00:30:28,560 --> 00:30:32,080 Speaker 1: down the view the wires towards the disk. If no, 583 00:30:32,600 --> 00:30:35,640 Speaker 1: throw it away. And so we have to make these 584 00:30:35,720 --> 00:30:38,120 Speaker 1: keep or kill decisions every twenty five nanoseconds. And when 585 00:30:38,160 --> 00:30:40,640 Speaker 1: it's gone, it's gone. It's not like it's saved to 586 00:30:40,720 --> 00:30:42,560 Speaker 1: back up and you can go through it another time. 587 00:30:42,640 --> 00:30:45,440 Speaker 1: It's just we just toss it out. And so that's 588 00:30:45,480 --> 00:30:48,040 Speaker 1: a really vital system. That's actually the part that my 589 00:30:48,120 --> 00:30:51,320 Speaker 1: group works on. Is this trigger system interesting? Yeah? I 590 00:30:51,560 --> 00:30:54,840 Speaker 1: always thought when I was learning more about this, I 591 00:30:54,920 --> 00:30:58,040 Speaker 1: wrote an article about how the large Hadron collider works 592 00:30:58,120 --> 00:31:00,880 Speaker 1: as part of my work for how stuff works, And 593 00:31:01,480 --> 00:31:04,440 Speaker 1: while I was working on it, it struck me just 594 00:31:04,520 --> 00:31:11,120 Speaker 1: how amazing the actual apparatus is of creating these beams 595 00:31:11,120 --> 00:31:15,400 Speaker 1: and steering them and creating the collision points. And then 596 00:31:15,480 --> 00:31:19,520 Speaker 1: it occurred to me that as challenging as it is, 597 00:31:19,760 --> 00:31:25,280 Speaker 1: you know, as much learning and engineering and all the 598 00:31:25,360 --> 00:31:27,800 Speaker 1: expertise that would be required to make such a thing happen. 599 00:31:28,200 --> 00:31:33,000 Speaker 1: As impressive as that is, it's it's also incredibly impressive 600 00:31:33,120 --> 00:31:36,440 Speaker 1: to think about how do you deal with the information 601 00:31:36,480 --> 00:31:39,479 Speaker 1: that you generate from such a thing. It's so large, 602 00:31:39,640 --> 00:31:44,720 Speaker 1: and the ability to differentiate between what is interesting versus 603 00:31:44,760 --> 00:31:47,080 Speaker 1: what has already been known and therefore like this is 604 00:31:47,560 --> 00:31:52,320 Speaker 1: something that we don't necessarily need to consider because it's 605 00:31:52,440 --> 00:31:54,200 Speaker 1: this is this is like we might as well have 606 00:31:54,240 --> 00:31:56,360 Speaker 1: this etched on the side of a mountain already. We're good, 607 00:31:56,680 --> 00:32:00,400 Speaker 1: let's just concentrate this other stuff. Um. And as you 608 00:32:00,440 --> 00:32:03,480 Speaker 1: start to look at the challenges that people have with 609 00:32:03,600 --> 00:32:09,200 Speaker 1: big data in general, which is orders of magnitude smaller 610 00:32:09,240 --> 00:32:12,200 Speaker 1: than one is being generated at the LHC. But you 611 00:32:12,240 --> 00:32:15,160 Speaker 1: look at those challenges just like businesses who are saying like, 612 00:32:15,400 --> 00:32:17,680 Speaker 1: we don't even know what what data we have at 613 00:32:17,680 --> 00:32:21,440 Speaker 1: this point, and you think, well, that's troubling. Then you realize, well, 614 00:32:21,560 --> 00:32:25,360 Speaker 1: if we're having trouble with that, imagine the challenge of 615 00:32:25,480 --> 00:32:28,960 Speaker 1: sifting through all that information to find these gems, these 616 00:32:29,480 --> 00:32:34,360 Speaker 1: these indications of something unknown or not fully understood. And 617 00:32:34,440 --> 00:32:37,760 Speaker 1: it boggled my mind. So to me, that is one 618 00:32:37,800 --> 00:32:42,440 Speaker 1: of the the huge achievements was not just the incredible 619 00:32:43,000 --> 00:32:47,080 Speaker 1: technological triumph of building a particle accelerator as large and 620 00:32:47,120 --> 00:32:50,360 Speaker 1: as powerful as the LHC, but then creating the way 621 00:32:50,400 --> 00:32:53,400 Speaker 1: to deal with the information that's generated as a result. 622 00:32:53,920 --> 00:32:57,160 Speaker 1: And I think a lot of people don't necessarily appreciate 623 00:32:57,200 --> 00:33:01,560 Speaker 1: that or understand that because they're just thinking of, uh, 624 00:33:01,640 --> 00:33:05,520 Speaker 1: there's probably conceptualizing. You know, these these particles hitting each 625 00:33:05,560 --> 00:33:08,080 Speaker 1: other really at high speed, and then there's maybe a 626 00:33:08,080 --> 00:33:10,200 Speaker 1: flash of light or something, and then there's a little 627 00:33:10,200 --> 00:33:12,520 Speaker 1: squiggly line that goes off into the distance and you think, oh, 628 00:33:12,680 --> 00:33:16,160 Speaker 1: that was a cork, right. It's it's because these are 629 00:33:16,200 --> 00:33:20,200 Speaker 1: so far outside the normal experience, it's hard to think of, well, 630 00:33:20,240 --> 00:33:22,600 Speaker 1: i'll tell you some details about it. That's actually the 631 00:33:22,880 --> 00:33:26,120 Speaker 1: part of it that I'm most interested in UM. But 632 00:33:26,200 --> 00:33:28,240 Speaker 1: first of the human side of it is that this 633 00:33:28,280 --> 00:33:31,880 Speaker 1: apparatus is so complex that everybody who participates and it's 634 00:33:31,920 --> 00:33:34,520 Speaker 1: you know, tens of thousands of scientists all working together. 635 00:33:34,840 --> 00:33:37,960 Speaker 1: Certainly not my project by myself. Everybody who participates only 636 00:33:38,000 --> 00:33:40,720 Speaker 1: does a little bit. You know, the people who specialize 637 00:33:40,720 --> 00:33:43,280 Speaker 1: in getting the beams to go really high speed, and 638 00:33:43,320 --> 00:33:45,920 Speaker 1: people who specialize in focusing the beams, and people who 639 00:33:45,920 --> 00:33:49,240 Speaker 1: specialize in building the detectors that surround the beam, and 640 00:33:49,240 --> 00:33:52,400 Speaker 1: people who specialize in um in the trigger, and people 641 00:33:52,400 --> 00:33:55,000 Speaker 1: who specialize in analyzing the data. And one of the 642 00:33:55,000 --> 00:33:57,480 Speaker 1: cool things is that you can specialize. You can say 643 00:33:57,760 --> 00:33:59,920 Speaker 1: I really like climbing around the detector with a wrench 644 00:34:00,000 --> 00:34:01,480 Speaker 1: and I want to spend my days doing that, or 645 00:34:01,520 --> 00:34:03,720 Speaker 1: you can say, oh, I'm really interested in the data 646 00:34:03,800 --> 00:34:06,640 Speaker 1: reduction problem. And so we sort of get to attract 647 00:34:06,640 --> 00:34:08,800 Speaker 1: all types and people who are good at different things, 648 00:34:08,840 --> 00:34:10,680 Speaker 1: and everybod gets to do the part they want rather 649 00:34:10,680 --> 00:34:13,359 Speaker 1: than having to do all of it by themselves. UM. 650 00:34:13,480 --> 00:34:16,319 Speaker 1: So I think that's really fun. And the part that 651 00:34:16,360 --> 00:34:19,240 Speaker 1: I'm most interested in is exactly what you were just mentioning, 652 00:34:19,360 --> 00:34:21,120 Speaker 1: is how do you go from this huge pile of 653 00:34:21,200 --> 00:34:24,200 Speaker 1: data to saying things about the universe right to say, 654 00:34:24,360 --> 00:34:26,319 Speaker 1: I've got all these zeros and ones. How do I 655 00:34:26,360 --> 00:34:28,640 Speaker 1: then say, oh, look, we have the Higgs boson, we 656 00:34:28,719 --> 00:34:31,560 Speaker 1: know it exists, or we found dark matter or something 657 00:34:31,600 --> 00:34:34,440 Speaker 1: like that. And and one of the problems is that 658 00:34:34,480 --> 00:34:36,680 Speaker 1: we don't create these particles and then like have them 659 00:34:36,680 --> 00:34:39,200 Speaker 1: in a jar. It's not like we're producing a pile 660 00:34:39,280 --> 00:34:41,200 Speaker 1: of higgs bosons and we can point them to them 661 00:34:41,239 --> 00:34:43,759 Speaker 1: and say, look, these are higgs bosons. You can tell 662 00:34:44,000 --> 00:34:45,840 Speaker 1: you can touch them, or they have some weird property 663 00:34:45,920 --> 00:34:48,440 Speaker 1: or something right the way, like in condensed matter, they 664 00:34:48,440 --> 00:34:50,680 Speaker 1: can make new kinds of goo and then they can 665 00:34:50,719 --> 00:34:53,000 Speaker 1: show it to you. And then, as with strange effects 666 00:34:53,080 --> 00:34:56,359 Speaker 1: or something, the higgs bosons that we produce only last 667 00:34:56,400 --> 00:34:59,560 Speaker 1: for like ten to the minus twenty something seconds. So 668 00:34:59,640 --> 00:35:02,200 Speaker 1: this this picture I told you where the corks collide, 669 00:35:02,239 --> 00:35:05,080 Speaker 1: they turned into something um some energy. Then they turned 670 00:35:05,120 --> 00:35:07,400 Speaker 1: into a new particle. That's true, but that new particle 671 00:35:07,800 --> 00:35:10,160 Speaker 1: might only last for a really really short amount of 672 00:35:10,160 --> 00:35:12,040 Speaker 1: time because a lot of these particles are very heavy 673 00:35:12,040 --> 00:35:14,080 Speaker 1: and unstable, and they don't like to live very long, 674 00:35:14,440 --> 00:35:17,920 Speaker 1: unlike you know, electrons or protons which can last for 675 00:35:18,000 --> 00:35:20,560 Speaker 1: billions or trillions of years. We don't even know. Some 676 00:35:20,640 --> 00:35:23,200 Speaker 1: of these particles are inherently unstable and they turn into 677 00:35:23,280 --> 00:35:25,920 Speaker 1: other particles, and so what we see in our detector 678 00:35:26,000 --> 00:35:30,040 Speaker 1: is never direct proof of that new particle. Instead, it's 679 00:35:30,120 --> 00:35:35,200 Speaker 1: always indirect evidence. It's like, um, you came to a um, 680 00:35:35,200 --> 00:35:37,759 Speaker 1: it came to an intersection, and you see, you know, 681 00:35:37,840 --> 00:35:39,680 Speaker 1: shards in the ground. You see glass over here, and 682 00:35:39,719 --> 00:35:42,000 Speaker 1: you see steel over there, and there's a dead body 683 00:35:42,040 --> 00:35:44,120 Speaker 1: over here, and you have to figure out what happened. 684 00:35:44,440 --> 00:35:46,799 Speaker 1: It's always like that that we're we're looking at what 685 00:35:46,920 --> 00:35:49,200 Speaker 1: came out of the collision and trying to figure out 686 00:35:49,200 --> 00:35:51,360 Speaker 1: what happened in the middle. And so a lot of 687 00:35:51,400 --> 00:35:54,680 Speaker 1: what we do is is really complicated statistical inference. We say, 688 00:35:54,920 --> 00:35:57,680 Speaker 1: given the data that we saw, which theory of the 689 00:35:57,719 --> 00:36:00,200 Speaker 1: universe is more likely in the theory with the Eggs 690 00:36:00,200 --> 00:36:03,120 Speaker 1: boson or without the Higgs boson. So most of the 691 00:36:03,160 --> 00:36:06,920 Speaker 1: actual work involved is in constructing those two hypotheses and 692 00:36:06,960 --> 00:36:10,480 Speaker 1: comparing them to the data, saying how can we analyze 693 00:36:10,480 --> 00:36:12,839 Speaker 1: the data, how can we um you know, plow through 694 00:36:12,880 --> 00:36:15,560 Speaker 1: the data in a way so that these two hypotheses 695 00:36:15,600 --> 00:36:18,160 Speaker 1: give different predictions. Like in the case of the search 696 00:36:18,160 --> 00:36:21,759 Speaker 1: for the Higgs boson, we were looking for collisions that 697 00:36:21,840 --> 00:36:25,839 Speaker 1: had to photons coming out. So two protons come in, 698 00:36:26,080 --> 00:36:28,960 Speaker 1: two photons come out, right, two little beams of light. 699 00:36:29,520 --> 00:36:32,800 Speaker 1: And that's because the higgs boson um sometimes turns into 700 00:36:32,800 --> 00:36:35,800 Speaker 1: two photons, So we're looking for two photons. The problem 701 00:36:35,840 --> 00:36:39,000 Speaker 1: is there are other things that also turned into two photons, 702 00:36:39,200 --> 00:36:41,279 Speaker 1: lots of ways to make two photons that aren't the 703 00:36:41,320 --> 00:36:45,000 Speaker 1: Higgs boson. But if you did make the Higgs boson 704 00:36:45,120 --> 00:36:47,960 Speaker 1: and it turned into two photons, then it would turn 705 00:36:48,000 --> 00:36:50,520 Speaker 1: into two photons with a certain amount of energy, and 706 00:36:50,560 --> 00:36:53,080 Speaker 1: that amount of energy is connected to how much mass 707 00:36:53,160 --> 00:36:55,680 Speaker 1: is in the higgs boson. So we did is we 708 00:36:55,719 --> 00:36:58,640 Speaker 1: just said, let's look at all the collisions that turned 709 00:36:58,640 --> 00:37:01,520 Speaker 1: into two photons, and let's just compare, and we made 710 00:37:01,520 --> 00:37:03,239 Speaker 1: sort of a plot where we said, on the X 711 00:37:03,280 --> 00:37:05,920 Speaker 1: axis is the amount of energy and the collisions, and 712 00:37:05,920 --> 00:37:09,040 Speaker 1: then why excess is the number. So if you're envisioning this, 713 00:37:09,400 --> 00:37:11,799 Speaker 1: we have one theory that says there should be a 714 00:37:11,840 --> 00:37:14,920 Speaker 1: smooth distribution, and then what the theory with the Higgs 715 00:37:14,920 --> 00:37:17,319 Speaker 1: boson says, well, there should be a smooth distribution, but 716 00:37:17,320 --> 00:37:18,880 Speaker 1: then you should you should get a bump, You should 717 00:37:18,880 --> 00:37:22,200 Speaker 1: get an enhancement around the mass of the Higgs. So 718 00:37:22,800 --> 00:37:25,360 Speaker 1: one theory is there is no Higgs boson, and you 719 00:37:25,400 --> 00:37:28,080 Speaker 1: should get a bunch of just random collisions with two photons, 720 00:37:28,320 --> 00:37:32,319 Speaker 1: no special energy levels. And the other theory is you 721 00:37:32,520 --> 00:37:35,279 Speaker 1: have a Higgs boson, which means you get extra production 722 00:37:35,360 --> 00:37:38,000 Speaker 1: of two photon events and they should cluster and they 723 00:37:38,000 --> 00:37:40,439 Speaker 1: should all have a similar energy. So if you make 724 00:37:40,480 --> 00:37:43,560 Speaker 1: this uh this plot, you should get a bump near 725 00:37:43,600 --> 00:37:46,000 Speaker 1: the mass of the Higgs. And so essentially we have 726 00:37:46,040 --> 00:37:49,640 Speaker 1: two hypotheses. We say no Higgs boson or Higgs boson, 727 00:37:49,880 --> 00:37:52,200 Speaker 1: and then we look at the data. So we've done 728 00:37:52,200 --> 00:37:55,960 Speaker 1: the hard work of constructing two possible ideas and figuring 729 00:37:56,000 --> 00:37:59,200 Speaker 1: out what question to ask the data. That's always the 730 00:37:59,200 --> 00:38:01,919 Speaker 1: crucial thing. It's a question are you asking the data? 731 00:38:02,120 --> 00:38:04,360 Speaker 1: And we've composed the question in a way that we 732 00:38:04,440 --> 00:38:06,880 Speaker 1: hope the data can answer it. And that's how we 733 00:38:06,920 --> 00:38:10,240 Speaker 1: discover the Higgs boson. Is the data followed one curve, 734 00:38:10,280 --> 00:38:11,920 Speaker 1: the curve with a bump in it, and not the 735 00:38:11,960 --> 00:38:15,160 Speaker 1: smooth curve, the curve that had no Higgs boson. So 736 00:38:15,200 --> 00:38:17,720 Speaker 1: a lot of the work we do is involved in 737 00:38:17,719 --> 00:38:21,880 Speaker 1: in analyzing that data, and because it's such a big project, 738 00:38:22,160 --> 00:38:25,319 Speaker 1: we have people specializing in these areas, and this is 739 00:38:25,360 --> 00:38:28,319 Speaker 1: my area specialty is analyzing this data. And one of 740 00:38:28,320 --> 00:38:32,040 Speaker 1: my other interests is in computer science and artificial intelligence. 741 00:38:32,400 --> 00:38:35,240 Speaker 1: And in the last five years we've been borrowing really 742 00:38:35,320 --> 00:38:38,880 Speaker 1: heavily from computer science all these new tools they've developed 743 00:38:38,880 --> 00:38:43,920 Speaker 1: to do really fantastical artificial intelligence to recognize patterns. We 744 00:38:44,000 --> 00:38:46,279 Speaker 1: found ways to take those tools and apply them to 745 00:38:46,360 --> 00:38:49,960 Speaker 1: these questions to say to artificial intelligence tools, can you 746 00:38:50,000 --> 00:38:53,160 Speaker 1: find patterns in this data? Can you learn to find 747 00:38:53,239 --> 00:38:56,560 Speaker 1: Higgs bosons in these ones and zeros um and separate 748 00:38:56,600 --> 00:38:58,680 Speaker 1: them from things that are not higgs bosons but look 749 00:38:58,760 --> 00:39:01,160 Speaker 1: like them. So we've a lot of fun bringing in 750 00:39:01,200 --> 00:39:03,200 Speaker 1: ideas from other fields. We don't invent a lot of 751 00:39:03,200 --> 00:39:05,360 Speaker 1: this stuff by ourselves. We sort of you know, we 752 00:39:05,400 --> 00:39:07,720 Speaker 1: have a nail and we sift around for somebody nearby 753 00:39:07,800 --> 00:39:11,000 Speaker 1: who might have a hammer. M h. Well, that to 754 00:39:11,120 --> 00:39:14,960 Speaker 1: me is always a fascinating thing as well. It's it's 755 00:39:15,000 --> 00:39:19,359 Speaker 1: a different level of innovation where you are thinking rather 756 00:39:19,440 --> 00:39:22,359 Speaker 1: than let's let's invent a brand new tool to do 757 00:39:22,440 --> 00:39:25,000 Speaker 1: this thing. You say, well, do we have any tools 758 00:39:25,080 --> 00:39:28,239 Speaker 1: that perhaps are not currently being used to do this thing, 759 00:39:28,280 --> 00:39:31,600 Speaker 1: but with some some work, we could repurpose them for 760 00:39:31,640 --> 00:39:35,879 Speaker 1: this thing. Um to that, Usually it's a happy discovery. Yeah. 761 00:39:35,920 --> 00:39:38,360 Speaker 1: I remember going over to the computer science department it 762 00:39:38,440 --> 00:39:42,040 Speaker 1: was like two thousand twelve and describing this project and saying, look, 763 00:39:42,160 --> 00:39:44,720 Speaker 1: here's the problem we have. We don't have a tool 764 00:39:44,760 --> 00:39:47,120 Speaker 1: that can solve this problem. What do you have? And 765 00:39:47,120 --> 00:39:48,919 Speaker 1: they said, oh, my gosh, we have the perfect tool. 766 00:39:49,440 --> 00:39:51,960 Speaker 1: Currently we're using it to solve this other problem. And 767 00:39:51,960 --> 00:39:53,360 Speaker 1: I was like, well, what problem are you solving and 768 00:39:53,400 --> 00:39:55,759 Speaker 1: they said, oh, we're trying to figure out how to 769 00:39:55,760 --> 00:39:59,759 Speaker 1: answer the question is there a cat in this Internet video? Right? 770 00:39:59,760 --> 00:40:02,040 Speaker 1: Which is like the perfect example of how of a 771 00:40:02,200 --> 00:40:06,560 Speaker 1: hard but relevant problem. Like it's not easy to say, 772 00:40:06,600 --> 00:40:09,160 Speaker 1: here's a video, can you tell me if there's a cadet? 773 00:40:09,239 --> 00:40:10,800 Speaker 1: It's the kind of thing it's easy for a person, 774 00:40:11,200 --> 00:40:13,920 Speaker 1: but it's really hard for a computer program. Right, how 775 00:40:13,960 --> 00:40:16,480 Speaker 1: do you define a cat? And then it's moving through 776 00:40:16,520 --> 00:40:19,600 Speaker 1: the videos on different colors of cats, cats, of different behaviors. 777 00:40:19,800 --> 00:40:22,440 Speaker 1: It's a difficult problem and it's one where there's a 778 00:40:22,480 --> 00:40:25,560 Speaker 1: lot of data available. So the computer scientists latched onto 779 00:40:25,560 --> 00:40:28,800 Speaker 1: this problem not because it was important or particularly interesting 780 00:40:28,880 --> 00:40:31,759 Speaker 1: or useful, but just because it was hard and they 781 00:40:31,800 --> 00:40:33,920 Speaker 1: had a lot of data. So when I came to 782 00:40:34,000 --> 00:40:36,640 Speaker 1: them with another problem that was hard, where we had 783 00:40:36,640 --> 00:40:39,719 Speaker 1: a lot of data but actually had some like scientific 784 00:40:39,800 --> 00:40:44,000 Speaker 1: value and and sounded cool, they were very excited. So 785 00:40:44,040 --> 00:40:46,000 Speaker 1: they're excited to get to use their tool and something 786 00:40:46,040 --> 00:40:49,240 Speaker 1: that was actually relevant to society into physics and to science. 787 00:40:49,640 --> 00:40:51,839 Speaker 1: And we were excited, of course to use their awesome tool, 788 00:40:51,880 --> 00:40:54,359 Speaker 1: which worked really, really well. So it's usually a sort 789 00:40:54,360 --> 00:40:56,239 Speaker 1: of a peanut butter and chocolate situation when you can 790 00:40:56,239 --> 00:40:59,640 Speaker 1: find this sort of crossovers nice. I like, I like 791 00:40:59,680 --> 00:41:02,960 Speaker 1: the peanut ab her chocolate analogy. And of course, uh, 792 00:41:03,040 --> 00:41:06,240 Speaker 1: the neat thing to me about the machine learning process 793 00:41:06,320 --> 00:41:09,400 Speaker 1: that you were talking about with with identifying cats and 794 00:41:09,520 --> 00:41:13,719 Speaker 1: videos taking an approach like that, where again seemingly if 795 00:41:13,760 --> 00:41:16,799 Speaker 1: you if you explain that to someone, they sound they say, well, 796 00:41:16,840 --> 00:41:19,000 Speaker 1: that sounds like it's trivial. It's I mean, it may 797 00:41:19,000 --> 00:41:21,239 Speaker 1: be a hard computer problem, but what's the purpose. And 798 00:41:21,640 --> 00:41:25,120 Speaker 1: my argument to them has always been, well, a human 799 00:41:25,160 --> 00:41:27,400 Speaker 1: can immediately tell if the computer was right or wrong 800 00:41:27,600 --> 00:41:29,640 Speaker 1: when it or the machine was right or wrong when 801 00:41:29,640 --> 00:41:32,600 Speaker 1: it comes to its conclusion, and therefore go in and 802 00:41:32,600 --> 00:41:36,839 Speaker 1: tweak the waitings of the various decision points. That if 803 00:41:36,840 --> 00:41:39,440 Speaker 1: you're using an our official neural network, you change the 804 00:41:39,440 --> 00:41:43,200 Speaker 1: waitings of the the various values so that it can 805 00:41:43,480 --> 00:41:46,440 Speaker 1: slowly hone in on what is it to be a 806 00:41:46,480 --> 00:41:50,680 Speaker 1: cat and and understand what catness really is, not not 807 00:41:50,719 --> 00:41:53,600 Speaker 1: the character from Hunger Games, but what catness really is. 808 00:41:54,239 --> 00:41:59,479 Speaker 1: And that once you do that, yes, exactly, that's that's 809 00:41:59,480 --> 00:42:02,319 Speaker 1: exactly what you want to do. Right If you're trying 810 00:42:02,360 --> 00:42:04,319 Speaker 1: to create a tool like this, you want to pick 811 00:42:05,000 --> 00:42:08,319 Speaker 1: a goal where a human can say, yes, the the 812 00:42:08,360 --> 00:42:10,920 Speaker 1: computer has managed to hit that goal, or no, the 813 00:42:10,920 --> 00:42:14,320 Speaker 1: computer has not. So that way, once you've perfected the 814 00:42:14,360 --> 00:42:16,759 Speaker 1: approach and you can then start to apply it to 815 00:42:16,840 --> 00:42:21,160 Speaker 1: things where uh, we don't have as full of an understanding. 816 00:42:21,239 --> 00:42:24,240 Speaker 1: You know. It's the difference between supervised learning with machine 817 00:42:24,320 --> 00:42:27,920 Speaker 1: learning and unsupervised learning, and and to me, that's a 818 00:42:28,000 --> 00:42:30,840 Speaker 1: very fascinating area of study. I've talked about that a 819 00:42:30,840 --> 00:42:34,279 Speaker 1: lot on tech stuff as well, and uh, it also 820 00:42:34,360 --> 00:42:37,080 Speaker 1: gets into other issues that I won't. I won't dive 821 00:42:37,120 --> 00:42:40,160 Speaker 1: into here, things like the the need for transparency for 822 00:42:40,200 --> 00:42:42,400 Speaker 1: these kind of systems so that we understand how they 823 00:42:42,440 --> 00:42:45,560 Speaker 1: get to their conclusions and it's not just a black box, etcetera, etcetera. 824 00:42:45,600 --> 00:42:50,200 Speaker 1: But I digress. How does it know what a cat? Exactly? Exactly? Yeah, 825 00:42:50,360 --> 00:42:53,200 Speaker 1: interpreting these networks is very important. Yeah. If you get 826 00:42:53,239 --> 00:42:55,279 Speaker 1: to a point where you watch a video and you say, oh, 827 00:42:55,320 --> 00:42:56,880 Speaker 1: I didn't see a cat in there, but the computer 828 00:42:56,920 --> 00:42:58,600 Speaker 1: says there's a cat in there. The computer says, no, 829 00:42:58,640 --> 00:43:00,600 Speaker 1: there absolutely as a cat in there. Just because you 830 00:43:00,600 --> 00:43:02,160 Speaker 1: didn't see it doesn't mean it's not there. And then 831 00:43:02,520 --> 00:43:04,799 Speaker 1: you start to get a little worried, just thinking are 832 00:43:04,800 --> 00:43:07,920 Speaker 1: we are we heading toward how territory here? Let's uh, 833 00:43:08,080 --> 00:43:09,879 Speaker 1: let's pump the brakes a little bit and find out 834 00:43:09,880 --> 00:43:11,840 Speaker 1: how you got to this happened to seed to the 835 00:43:11,840 --> 00:43:14,200 Speaker 1: computers the job of determining whether is the cat in 836 00:43:14,200 --> 00:43:17,839 Speaker 1: the video? They're better than I am. You say that, 837 00:43:17,880 --> 00:43:23,000 Speaker 1: but I find cat video so cathartic. Um. So this 838 00:43:23,600 --> 00:43:26,480 Speaker 1: one thing I wanted to to touch on just briefly, um, 839 00:43:26,840 --> 00:43:29,560 Speaker 1: And that might be difficult to do. But yeah, we 840 00:43:29,719 --> 00:43:33,000 Speaker 1: mentioned Higgs boson quite a quite a bit. And uh, 841 00:43:33,600 --> 00:43:36,520 Speaker 1: how would you describe what the Higgs boson is to 842 00:43:36,800 --> 00:43:40,719 Speaker 1: someone who's interested in it but doesn't have that background 843 00:43:40,840 --> 00:43:45,520 Speaker 1: in in physics. Yeah, so the Higgs boson is fascinating 844 00:43:45,520 --> 00:43:48,640 Speaker 1: little particle, and it's a sort of part of the 845 00:43:48,680 --> 00:43:52,560 Speaker 1: answer to the question what is stuff? You know, we 846 00:43:52,640 --> 00:43:55,200 Speaker 1: want to understand what are things made out of? But 847 00:43:55,280 --> 00:43:57,319 Speaker 1: part of that is understanding like what am I made 848 00:43:57,320 --> 00:44:00,840 Speaker 1: out of? What is the substance of me? And you 849 00:44:00,920 --> 00:44:04,040 Speaker 1: imagine that if you take yourself apart, you're made out 850 00:44:04,040 --> 00:44:06,319 Speaker 1: of molecules. Those molecules are made out of atoms. Those 851 00:44:06,360 --> 00:44:09,840 Speaker 1: atoms are made out of protons and electrons and neutrons, 852 00:44:09,880 --> 00:44:12,640 Speaker 1: and the protons are made out of quarks. So at 853 00:44:12,640 --> 00:44:14,759 Speaker 1: this point we can describe everything that you're made out 854 00:44:14,800 --> 00:44:18,120 Speaker 1: of in terms of quarks and electrons um. But what 855 00:44:18,280 --> 00:44:21,120 Speaker 1: we still don't know is what are those made out of? 856 00:44:21,160 --> 00:44:24,600 Speaker 1: Like do they get a little scoop of universe stuff? 857 00:44:24,640 --> 00:44:28,280 Speaker 1: You know, there's some sort of basic matter unit, and 858 00:44:28,320 --> 00:44:31,000 Speaker 1: we don't understand like how do they have mass? Where 859 00:44:31,000 --> 00:44:34,200 Speaker 1: does their mass come from? And it's a mystery because 860 00:44:34,560 --> 00:44:38,239 Speaker 1: in our theory, these particles are not little balls. Like 861 00:44:38,239 --> 00:44:40,840 Speaker 1: when I say a particle, you're probably imagining like a 862 00:44:40,880 --> 00:44:43,840 Speaker 1: little spinning beach ball, right, a tiny little dot of 863 00:44:43,920 --> 00:44:47,799 Speaker 1: actual stuff, but something with extent to it, something with size. Well, 864 00:44:47,800 --> 00:44:50,200 Speaker 1: in our current theory, these particles don't have any size. 865 00:44:50,239 --> 00:44:54,719 Speaker 1: Their dots their points in space, which means where is 866 00:44:54,760 --> 00:44:57,120 Speaker 1: the stuff to them? Right? Where is the mass? Where 867 00:44:57,160 --> 00:45:00,200 Speaker 1: does the mass come from? Um, there's no room for 868 00:45:00,280 --> 00:45:02,400 Speaker 1: any mass in a point. Right. If there's mass, there 869 00:45:02,600 --> 00:45:04,719 Speaker 1: have infinite density, which makes no sense at all. You 870 00:45:04,800 --> 00:45:07,600 Speaker 1: have like all these tiny black holes. So the Higgs 871 00:45:07,600 --> 00:45:09,200 Speaker 1: boson is in a way that is a way to 872 00:45:09,239 --> 00:45:12,000 Speaker 1: answer that. What it does is it says that the 873 00:45:12,080 --> 00:45:15,800 Speaker 1: mass the particles have doesn't come from a little scoop 874 00:45:15,840 --> 00:45:18,520 Speaker 1: of universe stuff that they got. Instead, you have to 875 00:45:18,520 --> 00:45:21,480 Speaker 1: think of it's sort of like a charge. Like when 876 00:45:21,520 --> 00:45:23,759 Speaker 1: I tell you an electron has a negative charge, that 877 00:45:23,800 --> 00:45:26,240 Speaker 1: doesn't bother you. But what if I told you electron 878 00:45:26,320 --> 00:45:28,680 Speaker 1: is a point particle there's no room for it. Would 879 00:45:28,680 --> 00:45:31,960 Speaker 1: you ask where does the negative charge go? Or is 880 00:45:32,000 --> 00:45:34,040 Speaker 1: there room for the negative charge? You just think of 881 00:45:34,080 --> 00:45:36,600 Speaker 1: negative charge is sort of like a label, something that 882 00:45:36,680 --> 00:45:39,120 Speaker 1: you can apply to a tiny dot. We should think 883 00:45:39,160 --> 00:45:42,400 Speaker 1: of mass the same way. Mass is not a little 884 00:45:42,719 --> 00:45:45,759 Speaker 1: serving of universe stuff. It's like a charge, and a 885 00:45:45,840 --> 00:45:48,360 Speaker 1: charge of something that tells us how things interact. So 886 00:45:48,400 --> 00:45:51,000 Speaker 1: an electron has a negative charge, which means it, you know, 887 00:45:51,200 --> 00:45:53,960 Speaker 1: um gets repelled from positive stuff, and they can interact 888 00:45:53,960 --> 00:45:57,960 Speaker 1: with photons and things like that. Um particles that have mass. 889 00:45:58,560 --> 00:46:01,320 Speaker 1: Um those particles that have mass us they have mass, 890 00:46:01,360 --> 00:46:03,400 Speaker 1: which is a charge. It tells us how it interacts 891 00:46:03,400 --> 00:46:06,440 Speaker 1: with the higgs boson. So the Higgs boson is the 892 00:46:06,480 --> 00:46:09,600 Speaker 1: thing that gives these that that interacts with these particles 893 00:46:09,640 --> 00:46:12,600 Speaker 1: and makes them move as if they had mass. So 894 00:46:12,640 --> 00:46:14,759 Speaker 1: they have some of the label on them, and the 895 00:46:14,840 --> 00:46:17,239 Speaker 1: higgs boson interacts with them if you have if you 896 00:46:17,280 --> 00:46:19,920 Speaker 1: have a lot of mass, higgs boson interacts with them 897 00:46:19,960 --> 00:46:22,120 Speaker 1: a lot, and that's what gives them inertia. It makes 898 00:46:22,440 --> 00:46:24,520 Speaker 1: makes it hard for them to speed up or hard 899 00:46:24,560 --> 00:46:27,440 Speaker 1: for them to slow down. Right, And so that's what 900 00:46:27,480 --> 00:46:29,719 Speaker 1: the Higgs boson does, is it gives mass to these 901 00:46:29,719 --> 00:46:32,839 Speaker 1: particles or explains how a tiny little particle can have 902 00:46:32,880 --> 00:46:37,000 Speaker 1: any mass at all. And the fascinating thing is that 903 00:46:37,040 --> 00:46:39,600 Speaker 1: the idea, who has been around for decades before we 904 00:46:39,640 --> 00:46:43,279 Speaker 1: actually found it. Some theorist was looking at the list 905 00:46:43,320 --> 00:46:46,279 Speaker 1: of particles and the math behind them and saying, this 906 00:46:46,320 --> 00:46:49,160 Speaker 1: doesn't really make sense, like how do these particles? How 907 00:46:49,160 --> 00:46:52,000 Speaker 1: can these particles have mass? There's no way to give 908 00:46:52,040 --> 00:46:54,480 Speaker 1: them mass in our theory. Like, we have a really 909 00:46:54,480 --> 00:46:57,720 Speaker 1: beautiful theory that would work perfectly if all the particles 910 00:46:57,719 --> 00:47:00,680 Speaker 1: in the universe had no mass, But the particles have mass, 911 00:47:01,120 --> 00:47:03,040 Speaker 1: and when you try to add mass in various ways, 912 00:47:03,040 --> 00:47:05,600 Speaker 1: it just doesn't work mathematically. It breaks all sorts of 913 00:47:05,600 --> 00:47:08,480 Speaker 1: other rules. So he came up with a way to 914 00:47:08,640 --> 00:47:11,000 Speaker 1: give mass to these particles by having them interact with 915 00:47:11,040 --> 00:47:13,960 Speaker 1: this other new particle we've never seen before. And the 916 00:47:14,000 --> 00:47:17,040 Speaker 1: thing I love about that is that it's it's purely aesthetic. 917 00:47:17,080 --> 00:47:19,839 Speaker 1: It's like philosophical. It's like saying, I'm looking at all 918 00:47:19,840 --> 00:47:22,440 Speaker 1: these puzzle pieces and it seems to be one missing. 919 00:47:22,880 --> 00:47:25,120 Speaker 1: This whole story, right, this move back to the idea 920 00:47:25,120 --> 00:47:27,040 Speaker 1: of a story. This whole story would make much more 921 00:47:27,080 --> 00:47:29,120 Speaker 1: sense if there was one more character in it. You 922 00:47:29,120 --> 00:47:31,600 Speaker 1: would just click together, would be symmetric, would be beautiful, 923 00:47:31,640 --> 00:47:35,200 Speaker 1: it would mathematically look pretty. And so he said, well, 924 00:47:35,320 --> 00:47:37,239 Speaker 1: maybe there is one, right, So let's go look for it, 925 00:47:37,280 --> 00:47:39,319 Speaker 1: and it was so compelling an idea that we spent 926 00:47:40,000 --> 00:47:42,279 Speaker 1: decades and billions of dollars looking for it and then 927 00:47:42,360 --> 00:47:45,600 Speaker 1: actually found it. Right. What a triumph for theoretical physics 928 00:47:45,680 --> 00:47:48,240 Speaker 1: to say, just in my mind, I can think about 929 00:47:48,239 --> 00:47:51,360 Speaker 1: the patterns of the universe and predict what else is 930 00:47:51,360 --> 00:47:54,959 Speaker 1: out there that we've never seen. To me, that's incredible. Yeah, 931 00:47:54,960 --> 00:47:58,560 Speaker 1: I love that. Uh it's a story where we take 932 00:47:58,600 --> 00:48:03,799 Speaker 1: a look at uh, an idea that's that's largely fleshed out, 933 00:48:04,280 --> 00:48:07,880 Speaker 1: and then we think, there's this would work so great 934 00:48:07,880 --> 00:48:10,520 Speaker 1: if only there was this thing. You know what, I'm 935 00:48:10,560 --> 00:48:14,000 Speaker 1: just gonna I'm going to create the mathematics here. I'm 936 00:48:14,000 --> 00:48:16,920 Speaker 1: gonna I'm gonna figure out mathematically how this thing could 937 00:48:16,920 --> 00:48:21,040 Speaker 1: exist if everything else we've assumed is more or less right, 938 00:48:21,680 --> 00:48:25,839 Speaker 1: And then, wow, that looks really nice. Boy, it would 939 00:48:25,840 --> 00:48:28,440 Speaker 1: be great if that thing exists. We should find out 940 00:48:28,440 --> 00:48:32,200 Speaker 1: if that thing exists, and then and then a lot 941 00:48:32,239 --> 00:48:34,640 Speaker 1: of time and thought is put to it. Not obviously 942 00:48:34,680 --> 00:48:38,000 Speaker 1: I'm trivializing and I'm very much generalizing, but to me, 943 00:48:38,080 --> 00:48:40,680 Speaker 1: it's just it is beautiful. But it's also there's like 944 00:48:40,680 --> 00:48:44,040 Speaker 1: a level there's a level of beautiful absurdity to it 945 00:48:44,560 --> 00:48:47,440 Speaker 1: that I find interesting from my perspective of not being 946 00:48:47,600 --> 00:48:51,319 Speaker 1: a physicist right where to me, it's it's no, you 947 00:48:51,360 --> 00:48:53,200 Speaker 1: sound like you kind of are an amateur physicist. I 948 00:48:53,239 --> 00:48:55,360 Speaker 1: mean you think about these ways like a physicist. You know, 949 00:48:55,360 --> 00:48:57,399 Speaker 1: it's not all about the mathematical training. It's so sort 950 00:48:57,440 --> 00:49:00,600 Speaker 1: about the front, the way you think, and the way 951 00:49:00,600 --> 00:49:03,479 Speaker 1: you ask questions. So I'm happy to bestow you upon 952 00:49:03,520 --> 00:49:07,560 Speaker 1: you the dubious honor of being a deputized amateur physicist. Excellent. 953 00:49:07,640 --> 00:49:13,280 Speaker 1: I cannot I cannot wait to abuse my authority certificate 954 00:49:13,280 --> 00:49:15,520 Speaker 1: in the mail pretty soon. Yeah, you'll see me walking 955 00:49:15,560 --> 00:49:17,640 Speaker 1: into restaurants saying, give me a good table. I am 956 00:49:17,680 --> 00:49:21,040 Speaker 1: an honorary physicist, and they'll say do you Yeah. No, 957 00:49:21,160 --> 00:49:23,960 Speaker 1: it doesn't work for for podcast celebrity either. I can 958 00:49:24,000 --> 00:49:27,440 Speaker 1: tell you from ten years of experience. Uh. Yeah, it's 959 00:49:27,440 --> 00:49:29,960 Speaker 1: the I have the level of fame that is almost 960 00:49:30,040 --> 00:49:33,359 Speaker 1: but not quite completely useless, and honestly I'm okay with that. 961 00:49:34,080 --> 00:49:36,839 Speaker 1: Um well, let me let me shift this a little bit. 962 00:49:36,840 --> 00:49:39,799 Speaker 1: We'll kind of uh get toward the end of our 963 00:49:39,840 --> 00:49:43,880 Speaker 1: conversation here to talk about some more silly fun stuff. 964 00:49:44,480 --> 00:49:46,080 Speaker 1: One of the things I think a lot of people 965 00:49:46,760 --> 00:49:50,000 Speaker 1: heard about when the LHC was, you know, still powering up. 966 00:49:50,040 --> 00:49:52,000 Speaker 1: It was a very long process. In fact, it was 967 00:49:52,040 --> 00:49:54,600 Speaker 1: longer than we had anticipated because there were some problems 968 00:49:54,640 --> 00:49:56,799 Speaker 1: that we encountered along the way. I say we, as 969 00:49:56,840 --> 00:49:58,840 Speaker 1: if I had anything to do with it. You're an 970 00:49:58,880 --> 00:50:02,520 Speaker 1: honorary physicist. Now you to say we they're excellent. It's 971 00:50:02,640 --> 00:50:05,520 Speaker 1: it's uh, it's so good to join the collective. But 972 00:50:05,719 --> 00:50:08,560 Speaker 1: the there were there were some issues, and it also 973 00:50:08,680 --> 00:50:13,120 Speaker 1: led to a lot of speculation, much of it completely 974 00:50:13,160 --> 00:50:17,400 Speaker 1: baseless from people who had uh, little to no understanding 975 00:50:17,400 --> 00:50:22,239 Speaker 1: of what was happening, but apparently access to wonderful platforms 976 00:50:22,280 --> 00:50:27,200 Speaker 1: from which they could espouse these these baseless claims. But 977 00:50:27,480 --> 00:50:31,520 Speaker 1: we had everything from people saying this is going to 978 00:50:31,560 --> 00:50:34,480 Speaker 1: create black holes without really one understanding what a black 979 00:50:34,480 --> 00:50:37,840 Speaker 1: hole is, to understanding if that were in fact to happen. 980 00:50:38,200 --> 00:50:41,320 Speaker 1: The time frame we're talking about, and the size the 981 00:50:41,320 --> 00:50:45,600 Speaker 1: the UH of it, and and what energy level we'd 982 00:50:45,640 --> 00:50:48,960 Speaker 1: be talking about less than what a mosquito generates when 983 00:50:48,960 --> 00:50:51,759 Speaker 1: it flaps its wings, for example, and at a at 984 00:50:51,760 --> 00:50:55,680 Speaker 1: a at a time that's so small that is impossible 985 00:50:55,719 --> 00:50:57,799 Speaker 1: for us to think of it. We can we could 986 00:50:57,880 --> 00:50:59,640 Speaker 1: look at a measurement. We could look at a number 987 00:51:00,160 --> 00:51:03,120 Speaker 1: with a whole bunch of zeros, you know, a dot, 988 00:51:03,200 --> 00:51:05,040 Speaker 1: a bunch of zeros, and then a one after it, 989 00:51:05,560 --> 00:51:07,680 Speaker 1: and think, oh, that's how long it is based on 990 00:51:07,719 --> 00:51:11,360 Speaker 1: you know, point zero, zero, zero, etcetera, etcetera, etcetera, one seconds. 991 00:51:12,000 --> 00:51:14,440 Speaker 1: But you can't by the time you think that, so 992 00:51:14,640 --> 00:51:17,960 Speaker 1: a countless number of those have passed. And so to me, 993 00:51:18,040 --> 00:51:22,120 Speaker 1: that was one of those things that I found funny 994 00:51:22,200 --> 00:51:26,879 Speaker 1: and infuriating at the same time, this sort of misconception about, oh, 995 00:51:26,920 --> 00:51:29,560 Speaker 1: the LHC is a doomsday device that is going to 996 00:51:29,840 --> 00:51:33,040 Speaker 1: end all life because we're going to create a black 997 00:51:33,040 --> 00:51:36,200 Speaker 1: hole that will suck up the entire universe. There's even, 998 00:51:36,239 --> 00:51:40,879 Speaker 1: as I recall, there's a website that had a very funny, 999 00:51:41,320 --> 00:51:46,280 Speaker 1: very immateurish gift of a picture supposedly from a security 1000 00:51:46,280 --> 00:51:50,440 Speaker 1: camera outside the LHC just getting sucked in to to 1001 00:51:50,520 --> 00:51:52,720 Speaker 1: a single point as if a black hole had been created, 1002 00:51:52,760 --> 00:51:56,520 Speaker 1: and I thought, wow, that's amazing. That's amazing connection to 1003 00:51:56,560 --> 00:52:01,759 Speaker 1: be able to continue to broadcast while spaghetti location is happening. Now, 1004 00:52:01,840 --> 00:52:05,560 Speaker 1: my favorite website is called has the Large Hadron Collider 1005 00:52:05,600 --> 00:52:09,000 Speaker 1: destroyed the world yet dot com as we promised as 1006 00:52:09,040 --> 00:52:12,480 Speaker 1: physicist to always keep up to date, right, So if 1007 00:52:12,480 --> 00:52:14,080 Speaker 1: you go to that website and it says yes, then 1008 00:52:14,160 --> 00:52:17,200 Speaker 1: you know, yeah, yeah, you might wanna, you might want to, 1009 00:52:17,320 --> 00:52:21,120 Speaker 1: you know, might make some plans. Um, But yeah, this 1010 00:52:21,160 --> 00:52:23,120 Speaker 1: is a this is a common thing that's raised, and 1011 00:52:23,280 --> 00:52:25,879 Speaker 1: I think it's reasonable for people to wonder, like our 1012 00:52:26,000 --> 00:52:29,279 Speaker 1: physicists going to trigger some sort of universal apocalypse which 1013 00:52:29,360 --> 00:52:33,320 Speaker 1: ends society as we know it. It's a fair question, um, 1014 00:52:33,360 --> 00:52:36,799 Speaker 1: But it's also reasonable for us to lean on physicists 1015 00:52:36,800 --> 00:52:39,040 Speaker 1: expertise and answering the question. In this case, I think 1016 00:52:39,080 --> 00:52:42,520 Speaker 1: Serain has done an excellent job of taking this concern seriously. 1017 00:52:43,239 --> 00:52:45,319 Speaker 1: So for those who don't know, there there really is 1018 00:52:45,360 --> 00:52:47,720 Speaker 1: a theory that we could be creating miniature black holes 1019 00:52:47,800 --> 00:52:51,520 Speaker 1: at the Large Hadron Collider. The idea is that gravity 1020 00:52:51,880 --> 00:52:54,560 Speaker 1: might be very very power. Gravity, which is the weakest force, 1021 00:52:54,680 --> 00:52:57,439 Speaker 1: might actually be very very powerful if you bring things 1022 00:52:57,600 --> 00:53:00,880 Speaker 1: really close together, like the close the size you know, 1023 00:53:00,920 --> 00:53:03,320 Speaker 1: the width of a proton is sort of close together. 1024 00:53:03,800 --> 00:53:06,080 Speaker 1: So if you smash these protons together really high energy, 1025 00:53:06,080 --> 00:53:08,839 Speaker 1: they might get close enough where the gravity gets really 1026 00:53:08,840 --> 00:53:11,959 Speaker 1: really strong, and meaning you could create black holes, because 1027 00:53:12,000 --> 00:53:14,720 Speaker 1: black holes are essentially displaces where gravity gets really strong. 1028 00:53:15,400 --> 00:53:18,440 Speaker 1: And if that's the case, those black holes, if they 1029 00:53:18,520 --> 00:53:20,839 Speaker 1: last long enough, could sit there and sort of swallow matter. 1030 00:53:21,200 --> 00:53:22,680 Speaker 1: But you know, there's lots of reasons not to be 1031 00:53:22,760 --> 00:53:24,680 Speaker 1: worried about that. First of all, we think if these 1032 00:53:24,719 --> 00:53:27,440 Speaker 1: black holes are created, they wouldn't last very long. They 1033 00:53:27,440 --> 00:53:31,520 Speaker 1: would radiate into nothing using Hawking radiation. And if they 1034 00:53:31,920 --> 00:53:35,759 Speaker 1: and and we believe that collisions have been happening for 1035 00:53:35,800 --> 00:53:38,239 Speaker 1: a long long time, like we've been being hit by 1036 00:53:38,280 --> 00:53:43,320 Speaker 1: particles from space forever basically, and those particles are traveling 1037 00:53:43,400 --> 00:53:45,800 Speaker 1: much faster than the particles at the large age On collider. 1038 00:53:45,880 --> 00:53:49,320 Speaker 1: So if collisions of particles were going to cause Earth 1039 00:53:49,440 --> 00:53:52,480 Speaker 1: destroying black holes, it would have happened already. And so 1040 00:53:52,560 --> 00:53:56,000 Speaker 1: there's a pretty in depth analysis of this um And 1041 00:53:56,080 --> 00:53:57,680 Speaker 1: I think one thing that's funny about it is sort 1042 00:53:57,680 --> 00:53:59,799 Speaker 1: of the social aspect of it. Like if you ask 1043 00:53:59,880 --> 00:54:03,160 Speaker 1: of is this, is it possible for the LHC to 1044 00:54:03,200 --> 00:54:07,040 Speaker 1: destroy the universe, to destroy the Earth, The answer is technically, yes, 1045 00:54:07,080 --> 00:54:11,120 Speaker 1: it's possible. You don't want to talk about exactly, but 1046 00:54:11,160 --> 00:54:14,520 Speaker 1: there's a difference between you know, a scientific answer and 1047 00:54:14,560 --> 00:54:18,160 Speaker 1: a sort of a public relations answer where it's possible, 1048 00:54:18,200 --> 00:54:20,600 Speaker 1: but not to the level where it's really worth talking about. 1049 00:54:20,719 --> 00:54:24,280 Speaker 1: Like it's possible for me to disappear in quantum mechanically 1050 00:54:24,280 --> 00:54:28,000 Speaker 1: appear in Paris. Sure it's not impossible, but it's the 1051 00:54:28,040 --> 00:54:30,600 Speaker 1: real The odds are so remote nobody should factor that 1052 00:54:30,640 --> 00:54:33,520 Speaker 1: into their plans. And that's really what people are asking about, Like, 1053 00:54:33,880 --> 00:54:35,520 Speaker 1: is this possible at the level where we need to 1054 00:54:35,560 --> 00:54:38,040 Speaker 1: worry about it and make policy changes or you know, 1055 00:54:38,360 --> 00:54:41,440 Speaker 1: use it to base decisions on And the answer is no. Um. 1056 00:54:41,520 --> 00:54:43,520 Speaker 1: But you know, we as humans are pretty bad about 1057 00:54:43,920 --> 00:54:46,759 Speaker 1: thinking about dangers and making decisions based on that. You know, 1058 00:54:47,160 --> 00:54:49,680 Speaker 1: I should worry about being struck by lightning or being 1059 00:54:49,719 --> 00:54:51,880 Speaker 1: eaten by sharks, but we don't worry too much about 1060 00:54:51,920 --> 00:54:54,759 Speaker 1: handgun safety this kind of stuff. So as human as 1061 00:54:54,800 --> 00:54:57,960 Speaker 1: we we have our policies upside down. Or even you know, 1062 00:54:58,040 --> 00:55:01,319 Speaker 1: the likelihood of getting in even a minor accident in 1063 00:55:01,360 --> 00:55:05,399 Speaker 1: a car, I mean, that's incredibly likely compared to these 1064 00:55:05,400 --> 00:55:08,640 Speaker 1: other things. But these other things because they I think 1065 00:55:08,719 --> 00:55:12,399 Speaker 1: largely because they and they tap into that same part 1066 00:55:12,440 --> 00:55:16,520 Speaker 1: of our brains that finds fascination in the unknown. There's 1067 00:55:16,640 --> 00:55:20,120 Speaker 1: there's that related element, the fear of the unknown. The 1068 00:55:20,160 --> 00:55:23,560 Speaker 1: two are very close, and the less you know about something, 1069 00:55:23,600 --> 00:55:27,839 Speaker 1: the more likely you are to fear it um. And paradoxically, 1070 00:55:27,840 --> 00:55:30,480 Speaker 1: also the more you know about something, depending on what 1071 00:55:30,560 --> 00:55:33,240 Speaker 1: it is, the more you might start to fear it um. 1072 00:55:33,280 --> 00:55:35,840 Speaker 1: So it's it's a really interesting Oh boy, being human 1073 00:55:35,880 --> 00:55:39,320 Speaker 1: sure is great um. But in the end, it's all about, 1074 00:55:39,520 --> 00:55:42,160 Speaker 1: you know, trying to answer these questions and exploring the unknown, 1075 00:55:42,160 --> 00:55:44,359 Speaker 1: and to me, that's always worth it. The guys who 1076 00:55:44,520 --> 00:55:46,520 Speaker 1: jumped in a ship and sailed into the ocean not 1077 00:55:46,600 --> 00:55:48,520 Speaker 1: knowing what they were going to find, you know, they 1078 00:55:48,520 --> 00:55:50,440 Speaker 1: were part of that. It's a it's a long legacy 1079 00:55:50,440 --> 00:55:52,640 Speaker 1: of exploration and to me, that's one of the most 1080 00:55:52,640 --> 00:55:55,719 Speaker 1: exciting things we can do as a species. Daniel, thank 1081 00:55:55,719 --> 00:55:58,359 Speaker 1: you so much for joining our show. Please can you 1082 00:55:58,560 --> 00:56:01,680 Speaker 1: tell us a little bit about your podcast and why 1083 00:56:01,760 --> 00:56:05,239 Speaker 1: everyone needs to listen to it? Sure? Our podcast is 1084 00:56:05,280 --> 00:56:08,520 Speaker 1: called Daniel and Jorge Explain the Universe. I'm one half 1085 00:56:08,560 --> 00:56:11,120 Speaker 1: of it. The other half is Jorge Chom, the internet 1086 00:56:11,160 --> 00:56:15,479 Speaker 1: famous cartoons behind PhD Comics, and we do a fun 1087 00:56:15,640 --> 00:56:18,799 Speaker 1: chat about philosophy and science and try to explain things 1088 00:56:18,840 --> 00:56:21,000 Speaker 1: about the universe and the idea there is to take 1089 00:56:21,080 --> 00:56:23,799 Speaker 1: big topics and break them up into pieces that are 1090 00:56:23,840 --> 00:56:26,360 Speaker 1: actually understandable, not just so you hear a lot of 1091 00:56:26,360 --> 00:56:28,600 Speaker 1: fancy words and you don't really understand, but so that 1092 00:56:28,640 --> 00:56:30,759 Speaker 1: you come away with a pretty good grasp of what 1093 00:56:30,840 --> 00:56:33,120 Speaker 1: these topics are. And we cover things like the Big 1094 00:56:33,160 --> 00:56:37,120 Speaker 1: Bang and teleportation and fasten the light travel and history 1095 00:56:37,120 --> 00:56:39,080 Speaker 1: of the universe and the future of the universe. And 1096 00:56:39,120 --> 00:56:40,960 Speaker 1: so check it out. It's a lot of fun. It's 1097 00:56:40,960 --> 00:56:45,040 Speaker 1: called Daniel and Jorge Explain the Universe. Yeah, it's fantastic, guys. 1098 00:56:45,040 --> 00:56:46,920 Speaker 1: If you have not listened, you need to check it out. 1099 00:56:47,120 --> 00:56:50,440 Speaker 1: I very much enjoyed it's I consider it sort of 1100 00:56:50,480 --> 00:56:56,239 Speaker 1: a spiritual cousin to text stuff and and and it 1101 00:56:56,239 --> 00:56:58,239 Speaker 1: makes me. It makes me long for the day when 1102 00:56:58,280 --> 00:57:00,640 Speaker 1: I can I can get a co host who I 1103 00:57:00,719 --> 00:57:03,040 Speaker 1: can bounce stuff off of, and they can bounce stuff 1104 00:57:03,080 --> 00:57:07,000 Speaker 1: off of me. Right now, I'm playing tennis with myself, 1105 00:57:07,080 --> 00:57:10,200 Speaker 1: so that is always a challenge. Daniel, thank you so 1106 00:57:10,320 --> 00:57:13,960 Speaker 1: much for joining the show. We greatly appreciate it. Thanks 1107 00:57:14,000 --> 00:57:15,600 Speaker 1: very much for having me on. And hello to all 1108 00:57:15,640 --> 00:57:18,840 Speaker 1: your listeners. Hey, guys, Jonathan from the future again. It's 1109 00:57:18,880 --> 00:57:23,320 Speaker 1: pretty awesome. They're flying cars and everything. Anyway, uh, I 1110 00:57:23,400 --> 00:57:24,760 Speaker 1: was just here to tell you we're going to take 1111 00:57:24,760 --> 00:57:35,320 Speaker 1: another quick break to thank our sponsor. That was a 1112 00:57:35,320 --> 00:57:38,080 Speaker 1: phenomenal conversation, or at least I had a ton of fun. 1113 00:57:38,120 --> 00:57:42,680 Speaker 1: I hope you guys enjoyed it. Daniel Whiteson is really 1114 00:57:42,880 --> 00:57:46,840 Speaker 1: great at communicating science, not just someone who practices it, 1115 00:57:47,240 --> 00:57:50,520 Speaker 1: but it's very good at explaining the wonder behind science. 1116 00:57:50,520 --> 00:57:53,520 Speaker 1: So definitely check out that podcast. If you guys have 1117 00:57:53,560 --> 00:57:56,840 Speaker 1: any suggestions for future topics for tech Stuff, whether it's 1118 00:57:56,840 --> 00:57:59,320 Speaker 1: a technology, a company, maybe there's someone else I should 1119 00:57:59,320 --> 00:58:02,800 Speaker 1: interview on the show, let me know. Send me an email. 1120 00:58:02,840 --> 00:58:06,800 Speaker 1: The addresses tech Stuff at how stuff works dot com, 1121 00:58:06,920 --> 00:58:09,480 Speaker 1: or you can visit our website that is tech Stuff 1122 00:58:09,560 --> 00:58:12,400 Speaker 1: podcast dot com.
