1 00:00:08,680 --> 00:00:13,400 Speaker 1: Hey everyone, Daniel here. For six years and six hundred episodes, 2 00:00:13,640 --> 00:00:17,480 Speaker 1: I've been talking to you about how wonderful and mysterious 3 00:00:17,640 --> 00:00:20,400 Speaker 1: our universe is. I've tried to guide you in how 4 00:00:20,400 --> 00:00:23,360 Speaker 1: to think about quantum mechanics, how to wrap your head 5 00:00:23,400 --> 00:00:26,759 Speaker 1: around relativity, and even how to help your teenager with 6 00:00:26,880 --> 00:00:30,120 Speaker 1: their chemistry homework when you have to. Or maybe that's 7 00:00:30,240 --> 00:00:32,360 Speaker 1: just me. Along the way, We've made a lot of 8 00:00:32,400 --> 00:00:35,640 Speaker 1: silly jokes about bananas and chocolate and anything else we 9 00:00:35,680 --> 00:00:37,360 Speaker 1: could think of to keep the mood light and to 10 00:00:37,400 --> 00:00:41,279 Speaker 1: make everybody feel welcome in this exploration of the universe. 11 00:00:41,560 --> 00:00:44,080 Speaker 1: And it's been a pleasure an honor to host this 12 00:00:44,200 --> 00:00:46,919 Speaker 1: show and to be your guide into the joys of 13 00:00:47,120 --> 00:00:51,040 Speaker 1: understanding the cosmos, because I really do think that the 14 00:00:51,159 --> 00:00:54,840 Speaker 1: universe can be explained, and that it deserves to be explained, 15 00:00:54,880 --> 00:00:58,640 Speaker 1: and that you deserve that explanation. When we started, I 16 00:00:58,640 --> 00:01:01,360 Speaker 1: had no idea how long this podcast would go for. 17 00:01:01,800 --> 00:01:04,920 Speaker 1: After two hundred, three hundred or five hundred episodes, I 18 00:01:05,000 --> 00:01:08,960 Speaker 1: was amazed that people still had an appetite for more physics. 19 00:01:08,520 --> 00:01:10,920 Speaker 2: And more Dad humor. But it was never. 20 00:01:10,800 --> 00:01:14,120 Speaker 1: Gonna last forever, and so it's with some wistfulness and 21 00:01:14,160 --> 00:01:16,360 Speaker 1: a lot of gratitude that I share with you today 22 00:01:16,400 --> 00:01:20,560 Speaker 1: at the news that this episode is our farewell episode. 23 00:01:20,840 --> 00:01:24,319 Speaker 1: But don't worry, neither the universe nor I are going 24 00:01:24,360 --> 00:01:25,520 Speaker 1: away just yet. 25 00:01:41,040 --> 00:01:41,959 Speaker 2: Hi. I'm Daniel. 26 00:01:42,000 --> 00:01:44,400 Speaker 1: I'm a particle physicist, and for the last few years 27 00:01:44,440 --> 00:01:47,480 Speaker 1: I've been the host of this podcast, Daniel and Jorge 28 00:01:47,640 --> 00:01:51,360 Speaker 1: Explain the Universe. I've had a rotating series of co hosts, 29 00:01:51,360 --> 00:01:54,120 Speaker 1: starting of course with Jorge, then going solo for a bit, 30 00:01:54,200 --> 00:01:56,480 Speaker 1: then Jorge came back, and then I was solo again. 31 00:01:57,000 --> 00:01:59,320 Speaker 1: Then I invited Kelly and Katie to join us as 32 00:01:59,360 --> 00:01:59,880 Speaker 1: co hosts. 33 00:02:00,200 --> 00:02:01,080 Speaker 2: Jorge returned. 34 00:02:01,280 --> 00:02:04,320 Speaker 1: But I've been here with you on every single episode 35 00:02:04,360 --> 00:02:07,560 Speaker 1: because this project means something to me. It means a 36 00:02:07,600 --> 00:02:10,320 Speaker 1: lot to me. I'm a physicist, of course, but I'm 37 00:02:10,360 --> 00:02:12,440 Speaker 1: also a professor, and that means that part of my 38 00:02:12,639 --> 00:02:16,400 Speaker 1: job is education, not just research. Of course, I teach 39 00:02:16,440 --> 00:02:20,239 Speaker 1: classes here at UC Irvine, from first year classical mechanics 40 00:02:20,280 --> 00:02:22,600 Speaker 1: all the way up to graduate level particle physics. But 41 00:02:22,680 --> 00:02:26,200 Speaker 1: I also want to help address the unsatisfied thirst people 42 00:02:26,280 --> 00:02:31,440 Speaker 1: out there have for jargon free, intuitive explanations about the universe. 43 00:02:31,720 --> 00:02:35,679 Speaker 1: Because there's this wonderful moment when ideas click together in 44 00:02:35,720 --> 00:02:39,440 Speaker 1: your mind, when you've understood something new and familiar, when 45 00:02:39,440 --> 00:02:41,960 Speaker 1: it makes sense in a way it didn't used to. 46 00:02:42,440 --> 00:02:44,840 Speaker 1: And I want to share those moments with all of you, 47 00:02:45,280 --> 00:02:48,520 Speaker 1: giving you a shortcut to the intuitive understanding of the 48 00:02:48,600 --> 00:02:52,000 Speaker 1: universe without having a way through years of mathematical training. 49 00:02:52,320 --> 00:02:54,920 Speaker 1: That's my major goal with this podcast and with my 50 00:02:54,919 --> 00:02:58,000 Speaker 1: book projects, to share the joy of understanding and the 51 00:02:58,000 --> 00:03:00,279 Speaker 1: allure of all the unanswered questions. 52 00:03:00,240 --> 00:03:01,000 Speaker 2: With all of you. 53 00:03:01,320 --> 00:03:03,600 Speaker 1: So thank you, thank you for being there with me. 54 00:03:03,880 --> 00:03:08,240 Speaker 1: And although this particular podcast won't be continuing my desire 55 00:03:08,280 --> 00:03:10,600 Speaker 1: to connect with all of you to explore what we 56 00:03:10,720 --> 00:03:14,560 Speaker 1: do and don't know about this incredible, bonkers, amazing universe 57 00:03:14,760 --> 00:03:17,760 Speaker 1: that isn't going away. So I'm very happy to announce 58 00:03:17,800 --> 00:03:22,519 Speaker 1: my new podcast, Daniel and Kelly's Extraordinary Universe. You all 59 00:03:22,560 --> 00:03:25,200 Speaker 1: know Kelly one of our wonderful co hosts on this pod. 60 00:03:25,320 --> 00:03:27,359 Speaker 1: She and I have always had fun talking about science 61 00:03:27,400 --> 00:03:29,840 Speaker 1: and joking around, and so we are launching this new project. 62 00:03:29,960 --> 00:03:32,480 Speaker 1: It's not exactly the same as explaining the Universe, but 63 00:03:32,520 --> 00:03:35,400 Speaker 1: I think that fans of this podcast will also enjoy 64 00:03:35,480 --> 00:03:38,120 Speaker 1: the new one. You'll recognize me, of course, and my 65 00:03:38,280 --> 00:03:40,800 Speaker 1: style of explanations, and you already know Kelly, and there 66 00:03:40,800 --> 00:03:43,680 Speaker 1: will be plenty of puns and silliness mixed in with 67 00:03:43,800 --> 00:03:46,840 Speaker 1: the science. More about that later, because today we are 68 00:03:46,880 --> 00:03:50,120 Speaker 1: here to say goodbye to Daniel and Jorge explain the universe, 69 00:03:50,200 --> 00:03:54,040 Speaker 1: to celebrate what we've accomplished, to remember our best moments, 70 00:03:54,080 --> 00:03:56,920 Speaker 1: and to think about all we have learned. So today 71 00:03:57,000 --> 00:04:04,920 Speaker 1: on the podcast, we're saying so long and thanks for 72 00:04:05,000 --> 00:04:07,600 Speaker 1: all the chocolate, to celebrate everything we have learned. I 73 00:04:07,600 --> 00:04:10,240 Speaker 1: went back and listened to a bunch of old episodes 74 00:04:10,400 --> 00:04:12,720 Speaker 1: to see how the podcast has changed. And you know, 75 00:04:12,840 --> 00:04:15,480 Speaker 1: through the years, the podcast has evolved a bit as 76 00:04:15,520 --> 00:04:18,039 Speaker 1: we found our rhythm, but you can hear the groove 77 00:04:18,080 --> 00:04:21,520 Speaker 1: that we found even in the earliest episodes. Here's a 78 00:04:21,560 --> 00:04:25,360 Speaker 1: couple of clips from the first two episodes of the podcast. 79 00:04:25,800 --> 00:04:27,400 Speaker 2: I'm Daniel. I'm a particle physicist. 80 00:04:27,520 --> 00:04:30,599 Speaker 1: I spend my days smashing protons together at the large 81 00:04:30,600 --> 00:04:33,679 Speaker 1: Hadron colliders to try to reveal the secrets of the universe, 82 00:04:33,839 --> 00:04:35,919 Speaker 1: mostly so that I can tell them to you in 83 00:04:35,960 --> 00:04:36,720 Speaker 1: this podcast. 84 00:04:37,160 --> 00:04:39,960 Speaker 3: Basically, only one of us is qualified to be explaining 85 00:04:40,000 --> 00:04:41,800 Speaker 3: things to you on this podcast. 86 00:04:41,520 --> 00:04:42,479 Speaker 2: That would be the cartoonist. 87 00:04:42,640 --> 00:04:46,920 Speaker 1: Yeah, physicists are not qualified usually to be explainers. Mostly 88 00:04:46,960 --> 00:04:48,960 Speaker 1: we just try to solve the mysteries of the universe. 89 00:04:48,960 --> 00:04:50,880 Speaker 1: We don't try to tell anybody about them. 90 00:04:50,920 --> 00:04:54,719 Speaker 3: Right, Mostly physicists just need explaining, that's right. 91 00:04:55,000 --> 00:04:56,599 Speaker 2: That's where the cartoons come in, right. 92 00:04:56,680 --> 00:05:00,560 Speaker 3: Yeah, and spouses also, spouses of physicists have to do 93 00:05:00,600 --> 00:05:01,560 Speaker 3: a lot of explaining. 94 00:05:01,800 --> 00:05:05,720 Speaker 2: You got some splaining to do, exactly. Yeah. 95 00:05:05,880 --> 00:05:08,360 Speaker 1: You have to imagine if somebody is running our universe 96 00:05:08,400 --> 00:05:11,239 Speaker 1: as a simulation, who knows what kind of computational powers 97 00:05:11,279 --> 00:05:16,160 Speaker 1: they have, right, And if they are their universe, the 98 00:05:16,160 --> 00:05:18,880 Speaker 1: one that our universe is running as a simulation inside 99 00:05:18,920 --> 00:05:21,839 Speaker 1: of doesn't have to follow the same laws as our universe. 100 00:05:21,920 --> 00:05:22,120 Speaker 2: Right. 101 00:05:22,240 --> 00:05:24,960 Speaker 1: If we're in a video game inside somebody else's universe, 102 00:05:25,120 --> 00:05:27,719 Speaker 1: our video game can have rules that don't exist outside 103 00:05:27,760 --> 00:05:28,400 Speaker 1: the video game. 104 00:05:28,480 --> 00:05:32,640 Speaker 3: Right, So they like f equals MA or general relativity 105 00:05:32,640 --> 00:05:35,520 Speaker 3: that could have been something they just made up because 106 00:05:35,560 --> 00:05:38,760 Speaker 3: they thought they would be fun or interesting, you know, 107 00:05:38,880 --> 00:05:42,560 Speaker 3: like like we like we create video games with crazy 108 00:05:42,680 --> 00:05:45,560 Speaker 3: physical rules. You know, Mario can jump half of the screen, 109 00:05:45,640 --> 00:05:49,080 Speaker 3: he can jump twenty feet up in the air, so 110 00:05:49,160 --> 00:05:52,080 Speaker 3: maybe that's that's what our physical laws are. They're just 111 00:05:52,160 --> 00:05:54,520 Speaker 3: kind of like, hey, let's make this fun universe where 112 00:05:54,600 --> 00:05:57,000 Speaker 3: f eqals maa. Is that kind of the idea. 113 00:05:56,800 --> 00:05:59,400 Speaker 1: That's exactly right, Yeah, that's exactly right. And I think 114 00:05:59,600 --> 00:06:02,600 Speaker 1: that's harshly the origin of this idea. You know, what 115 00:06:02,720 --> 00:06:05,479 Speaker 1: is physics doing? Ask yourself that physics is trying to 116 00:06:05,480 --> 00:06:08,480 Speaker 1: figure out what are the rules of this universe? 117 00:06:08,600 --> 00:06:08,880 Speaker 2: Right? 118 00:06:09,200 --> 00:06:13,000 Speaker 1: What are the underlying code that runs this universe? And 119 00:06:13,120 --> 00:06:15,839 Speaker 1: so now that we actually have pretty powerful computer programs, 120 00:06:16,000 --> 00:06:18,560 Speaker 1: people wonder, well, if you were in a computer program 121 00:06:18,839 --> 00:06:20,960 Speaker 1: and you were trying to figure out what the rules 122 00:06:20,960 --> 00:06:24,400 Speaker 1: of that simulated universe were, you'd essentially be trying to 123 00:06:24,560 --> 00:06:28,200 Speaker 1: understand what was the physics coded into that universe. 124 00:06:28,400 --> 00:06:29,320 Speaker 3: You would be a physicist. 125 00:06:29,320 --> 00:06:32,200 Speaker 1: So in some sense, yeah, you'd be a physicist exactly. 126 00:06:32,200 --> 00:06:35,400 Speaker 1: Physicists are trying to reverse engineer the source code of 127 00:06:35,440 --> 00:06:38,320 Speaker 1: the universe. Right, regardless of whether you believe the universe 128 00:06:38,400 --> 00:06:41,680 Speaker 1: is real or a simulation, it does seem to follow. 129 00:06:41,440 --> 00:06:43,760 Speaker 3: Some rules, right, So it's like when you first. 130 00:06:43,520 --> 00:06:45,200 Speaker 2: It's amazing that we can even discover those. 131 00:06:45,720 --> 00:06:47,400 Speaker 3: So it's kind of like when you first play Super 132 00:06:47,440 --> 00:06:50,440 Speaker 3: Mario or something, and you're just jumping around and moving 133 00:06:50,440 --> 00:06:53,480 Speaker 3: around trying to figure out how Mari moves. You're essentially 134 00:06:53,520 --> 00:06:56,480 Speaker 3: like being a physicist in that world. 135 00:06:56,880 --> 00:06:59,520 Speaker 1: Right, that's exactly right. Everybody who plays a video game 136 00:06:59,520 --> 00:07:02,960 Speaker 1: for the first time, exactly. 137 00:07:02,600 --> 00:07:05,920 Speaker 3: Let's give everybody who plays video games. 138 00:07:07,920 --> 00:07:08,360 Speaker 2: That's right. 139 00:07:08,360 --> 00:07:11,000 Speaker 1: That you just give a whole generation of listeners or 140 00:07:11,000 --> 00:07:13,120 Speaker 1: reason to stop doing their physics homework and turn on 141 00:07:13,160 --> 00:07:13,600 Speaker 1: their video. 142 00:07:13,760 --> 00:07:14,080 Speaker 4: Yes. 143 00:07:14,400 --> 00:07:17,000 Speaker 1: Of course, by the end, people we're familiar with my 144 00:07:17,160 --> 00:07:21,120 Speaker 1: opinions about chocolate, the scourge that is white chocolate, and 145 00:07:21,120 --> 00:07:24,240 Speaker 1: the tragedy that is a Hershey bar. Here's me interviewing 146 00:07:24,240 --> 00:07:27,440 Speaker 1: a chocolate expert on the Physics of Chocolate episode. Let's 147 00:07:27,440 --> 00:07:30,960 Speaker 1: talk about the Hershey bar also because it's iconic on 148 00:07:31,040 --> 00:07:33,520 Speaker 1: the podcast recently, I commented that I was not a 149 00:07:33,520 --> 00:07:36,120 Speaker 1: particular fan of the Hershey bar because it has this 150 00:07:36,280 --> 00:07:40,200 Speaker 1: sour flavor to it. Where does that sourness come from? 151 00:07:40,480 --> 00:07:43,040 Speaker 1: Is it some property of milk chocolate? Is it some 152 00:07:43,160 --> 00:07:46,920 Speaker 1: secret process that Hershey has? Why are Hershey bar so sour? 153 00:07:47,200 --> 00:07:51,840 Speaker 5: So the story is, and I'm sure a Hershey representative 154 00:07:51,880 --> 00:07:56,360 Speaker 5: may dispute my spin on this is we talked to 155 00:07:56,400 --> 00:07:58,640 Speaker 5: Europeans and say, you know, they got the process of 156 00:07:58,720 --> 00:08:04,280 Speaker 5: drying liquid milk wrong and that it became there's lipid 157 00:08:04,840 --> 00:08:10,720 Speaker 5: catalysis that creates organic acids that gives you the sour 158 00:08:10,840 --> 00:08:13,520 Speaker 5: character that you get from baby puke. 159 00:08:13,720 --> 00:08:15,679 Speaker 1: I'm sorry, did you just say baby puke? 160 00:08:15,760 --> 00:08:16,760 Speaker 2: I did? I did. 161 00:08:16,840 --> 00:08:20,000 Speaker 5: And I've heard those terms from other Hershey people, so 162 00:08:20,440 --> 00:08:22,600 Speaker 5: I'm not taking these terms out of context. 163 00:08:22,640 --> 00:08:24,960 Speaker 1: So we have it on the record from an expert 164 00:08:25,000 --> 00:08:27,520 Speaker 1: in chocolate that Hershey's tastes like baby puke. 165 00:08:27,600 --> 00:08:30,800 Speaker 5: All, yeah, that'll intribution on this one. 166 00:08:31,640 --> 00:08:33,400 Speaker 1: Of course, there were lots of moments when we dug 167 00:08:33,480 --> 00:08:35,640 Speaker 1: deep into the physics and really tried to give you 168 00:08:35,679 --> 00:08:39,280 Speaker 1: an understanding of how everything out there worked. Here's a 169 00:08:39,320 --> 00:08:42,080 Speaker 1: snapshot from our episode about the Higgs boson and the 170 00:08:42,080 --> 00:08:42,880 Speaker 1: Mexican hat. 171 00:08:43,120 --> 00:08:45,800 Speaker 3: So then maybe the universe. It's almost like, at some 172 00:08:45,840 --> 00:08:48,559 Speaker 3: point in the beginning of the universe, the universe somehow 173 00:08:48,760 --> 00:08:51,400 Speaker 3: got mass like it needs to be massless everything at 174 00:08:51,480 --> 00:08:53,800 Speaker 3: least the matter particles, And then something happened to this 175 00:08:53,840 --> 00:08:56,680 Speaker 3: field that made suddenly everything has messed exactly. 176 00:08:56,760 --> 00:09:00,520 Speaker 1: And that's the moment in the universe when electromagnet and 177 00:09:00,559 --> 00:09:03,160 Speaker 1: the weak force split off from each other. Because that's 178 00:09:03,160 --> 00:09:05,880 Speaker 1: what the Higgs boson does, is it breaks this symmetry 179 00:09:05,920 --> 00:09:08,920 Speaker 1: between electromagnetism and the weak force, which we think are 180 00:09:09,000 --> 00:09:12,040 Speaker 1: really all just one sort of big, happy force. But 181 00:09:12,200 --> 00:09:15,160 Speaker 1: the W and the Z particles, which carry the information 182 00:09:15,320 --> 00:09:17,800 Speaker 1: for the weak force, they're really really massive. And that 183 00:09:17,880 --> 00:09:20,120 Speaker 1: happened at that moment when the Higgs boson sort of 184 00:09:20,200 --> 00:09:23,840 Speaker 1: rolled away from the middle and settled at this large value. 185 00:09:24,040 --> 00:09:26,920 Speaker 1: And we call that electroweak symmetry breaking. So there was 186 00:09:26,960 --> 00:09:29,120 Speaker 1: a time in the early universe when we think the 187 00:09:29,160 --> 00:09:32,920 Speaker 1: weak force was as powerful as electricity and magnetism, and 188 00:09:32,960 --> 00:09:34,120 Speaker 1: then the Higgs broke it. 189 00:09:34,280 --> 00:09:35,800 Speaker 3: Oh, man, that Higgs. 190 00:09:35,840 --> 00:09:36,679 Speaker 2: What a bully. 191 00:09:38,400 --> 00:09:39,440 Speaker 3: The week fourth week. 192 00:09:39,679 --> 00:09:42,440 Speaker 1: It's just doing its job, man, it's just doing its job. 193 00:09:42,679 --> 00:09:44,520 Speaker 1: But we think of it this also in terms of 194 00:09:44,559 --> 00:09:47,920 Speaker 1: like phase transitions, Like the universe was very different before 195 00:09:47,960 --> 00:09:50,560 Speaker 1: this and very different after this moment. And you know, 196 00:09:50,679 --> 00:09:52,840 Speaker 1: people you might hear people talking about like how there 197 00:09:52,880 --> 00:09:56,840 Speaker 1: were different laws of physics before this phase transition or something, 198 00:09:57,240 --> 00:09:59,960 Speaker 1: and that's because you know, these things control how things offen, 199 00:10:00,440 --> 00:10:02,760 Speaker 1: that things have no mass, and the weak force is 200 00:10:02,840 --> 00:10:05,320 Speaker 1: very very powerful than the effective laws of physics, the 201 00:10:05,360 --> 00:10:08,280 Speaker 1: things we experience would be very different. Deep down, there's 202 00:10:08,320 --> 00:10:11,560 Speaker 1: still like the basic laws of physics underneath everything that 203 00:10:11,600 --> 00:10:14,640 Speaker 1: are controlling how this happens. Those don't change, but you 204 00:10:14,679 --> 00:10:16,840 Speaker 1: know the way the things end up interacting and the 205 00:10:16,880 --> 00:10:20,480 Speaker 1: way they come together to form complex matter, that does 206 00:10:20,640 --> 00:10:23,280 Speaker 1: change when you have one of these like big moments 207 00:10:23,320 --> 00:10:25,040 Speaker 1: in the universe. So that's why they call it like 208 00:10:25,080 --> 00:10:27,760 Speaker 1: a phase transition in the laws of physics. 209 00:10:28,040 --> 00:10:31,120 Speaker 3: Like things click together differently, depending maybe on the size 210 00:10:31,120 --> 00:10:33,800 Speaker 3: of the universe or the density of it. All right, well, 211 00:10:33,880 --> 00:10:36,760 Speaker 3: let's get into what this all means. Why is it 212 00:10:37,080 --> 00:10:40,640 Speaker 3: important that the Higgs field has this potential shape like 213 00:10:40,640 --> 00:10:41,400 Speaker 3: a Mexican head. 214 00:10:41,920 --> 00:10:45,240 Speaker 1: We had lots of fun talking science with Katie, of course. 215 00:10:45,559 --> 00:10:48,120 Speaker 1: Here's a snippet from our episode about the length of 216 00:10:48,160 --> 00:10:48,600 Speaker 1: the day. 217 00:10:49,000 --> 00:10:49,800 Speaker 2: Hi, I'm Daniel. 218 00:10:49,840 --> 00:10:52,880 Speaker 1: I'm a particle physicist and a professor at UC Irvine, 219 00:10:52,920 --> 00:10:54,920 Speaker 1: and I get paid whether I nap or not. 220 00:10:55,520 --> 00:10:59,760 Speaker 6: I am Katie. I am a professional napper. I am 221 00:11:00,040 --> 00:11:01,920 Speaker 6: so good at naps you wouldn't even believe it. I 222 00:11:01,960 --> 00:11:06,040 Speaker 6: also run a podcast called Creature Feature. I am a 223 00:11:06,080 --> 00:11:07,280 Speaker 6: biology educator. 224 00:11:07,400 --> 00:11:10,680 Speaker 1: Hmm, and have you ever had an episode about naps 225 00:11:10,679 --> 00:11:11,600 Speaker 1: in the animal world. 226 00:11:11,880 --> 00:11:13,000 Speaker 5: I actually have. 227 00:11:13,120 --> 00:11:16,280 Speaker 6: Like there's a lot of animals that do sleep in 228 00:11:16,360 --> 00:11:19,760 Speaker 6: weird ways, like little like micro naps that birds do, 229 00:11:19,880 --> 00:11:22,720 Speaker 6: where they do like little tiny, itty bitty naps throughout 230 00:11:22,720 --> 00:11:27,120 Speaker 6: the day in order to stay alert, or like weird 231 00:11:27,360 --> 00:11:30,680 Speaker 6: giraffe sleeping schedules where it's like they sleep in these 232 00:11:30,800 --> 00:11:33,640 Speaker 6: weird chunks and wake up throughout the night but sleep 233 00:11:33,720 --> 00:11:34,240 Speaker 6: like a lot. 234 00:11:34,320 --> 00:11:36,000 Speaker 2: It's very interesting the. 235 00:11:36,360 --> 00:11:38,520 Speaker 6: Idea of this, like you know, sleep during the night, 236 00:11:38,600 --> 00:11:41,160 Speaker 6: bewake during the day, and sleep in a solid chunk, 237 00:11:41,640 --> 00:11:44,960 Speaker 6: is very much just like a human quirk, right, A 238 00:11:45,000 --> 00:11:46,440 Speaker 6: lot of animals sleep differently. 239 00:11:46,520 --> 00:11:48,240 Speaker 1: Well, I wonder about that with my dog. I never 240 00:11:48,320 --> 00:11:51,120 Speaker 1: find him sleeping in the same place in the morning 241 00:11:51,280 --> 00:11:53,280 Speaker 1: as he went to sleep in the evening, and I wonder, like, 242 00:11:53,400 --> 00:11:55,080 Speaker 1: does he have a night sleep? Is he just like 243 00:11:55,440 --> 00:11:58,240 Speaker 1: napping a bunch because he also like sleeps most of 244 00:11:58,320 --> 00:11:58,800 Speaker 1: the day. 245 00:11:59,520 --> 00:12:01,199 Speaker 2: So what is my dog doing in the middle of 246 00:12:01,240 --> 00:12:01,440 Speaker 2: the night? 247 00:12:01,520 --> 00:12:05,840 Speaker 6: King he's online on dog Internet. 248 00:12:06,920 --> 00:12:09,880 Speaker 2: No, I'm recording his own podcast, wondering what I'm doing 249 00:12:11,360 --> 00:12:12,080 Speaker 2: rough stuff. 250 00:12:12,480 --> 00:12:16,200 Speaker 1: Yeah, And it was always fun to talk science with Kelly. 251 00:12:16,600 --> 00:12:19,040 Speaker 1: Here's a couple of clips from episodes with her. 252 00:12:19,200 --> 00:12:22,720 Speaker 7: And I'm Kelly Waiersmith. I'm a parasitologist who's adjunct with 253 00:12:22,800 --> 00:12:25,160 Speaker 7: Rice University, and I also like power. 254 00:12:26,280 --> 00:12:28,760 Speaker 1: Do you ever wish that you could just plug yourself 255 00:12:28,800 --> 00:12:29,760 Speaker 1: into solar power? 256 00:12:29,880 --> 00:12:29,960 Speaker 8: Like? 257 00:12:30,040 --> 00:12:31,920 Speaker 1: Why do we still need to sleep? Why can't we 258 00:12:32,000 --> 00:12:34,200 Speaker 1: just recharge the way all of our devices do? 259 00:12:34,400 --> 00:12:34,640 Speaker 9: Yeah? 260 00:12:34,800 --> 00:12:36,600 Speaker 7: Right, that would be like an upgrade of coffee. 261 00:12:36,640 --> 00:12:40,880 Speaker 1: I like it electrified coffee exactly. It just seems so 262 00:12:40,960 --> 00:12:42,800 Speaker 1: much more reliable. You know, those days you have, like 263 00:12:42,880 --> 00:12:44,800 Speaker 1: insomnia or whatever. You're like, I wish I could just 264 00:12:44,880 --> 00:12:46,679 Speaker 1: plug in and charge up today. 265 00:12:46,679 --> 00:12:49,120 Speaker 7: I overdid the coffee and I'm feeling kind of jittery. 266 00:12:49,240 --> 00:12:51,400 Speaker 7: So if I could just plug into a solar panel 267 00:12:51,440 --> 00:12:55,240 Speaker 7: and get nice, steady power without overdoing it, that would 268 00:12:55,240 --> 00:12:55,960 Speaker 7: be pretty solid. 269 00:12:56,000 --> 00:13:00,800 Speaker 1: Well maybe someday in the future, I know. I'm a 270 00:13:00,840 --> 00:13:04,160 Speaker 1: particle physicist and a professor at UC Irvine, and I 271 00:13:04,200 --> 00:13:07,080 Speaker 1: don't like scaring children, but I do like telling them 272 00:13:07,160 --> 00:13:07,640 Speaker 1: the truth. 273 00:13:10,280 --> 00:13:14,640 Speaker 7: I'm Kelly Wainer Smith. I'm an edgeuct professor at Rice University, 274 00:13:14,760 --> 00:13:16,160 Speaker 7: and I prefer lying to them. 275 00:13:17,120 --> 00:13:19,760 Speaker 1: What you lie to your kids, What if they ask 276 00:13:19,800 --> 00:13:21,760 Speaker 1: you a science question you don't know the answer, you 277 00:13:21,800 --> 00:13:22,440 Speaker 1: just make one up. 278 00:13:22,559 --> 00:13:22,719 Speaker 8: No. 279 00:13:22,920 --> 00:13:24,319 Speaker 7: In that case, I tell them the truth. 280 00:13:24,360 --> 00:13:25,400 Speaker 2: That's important, you know. 281 00:13:25,559 --> 00:13:27,880 Speaker 7: But one of them does still believe in Santa and 282 00:13:27,920 --> 00:13:31,479 Speaker 7: now will not be listening to this episode. 283 00:13:32,160 --> 00:13:34,839 Speaker 1: What if they ask you a science question that has 284 00:13:34,840 --> 00:13:36,080 Speaker 1: a scary answer. 285 00:13:36,000 --> 00:13:37,920 Speaker 7: It depends on if I think they can handle it 286 00:13:38,040 --> 00:13:39,880 Speaker 7: or not. And it depends on when I want to 287 00:13:39,920 --> 00:13:41,640 Speaker 7: go to bed that night, because I might be up 288 00:13:41,720 --> 00:13:44,760 Speaker 7: late doing the explaining. There's lots of things to consider, But. 289 00:13:44,800 --> 00:13:48,320 Speaker 1: Welcome to the podcast Daniel and Jorge Explain the Universe, 290 00:13:48,400 --> 00:13:52,000 Speaker 1: in which we try to teach you everything about the universe, 291 00:13:52,360 --> 00:13:55,360 Speaker 1: scary or not, the things that will keep you up 292 00:13:55,440 --> 00:13:57,760 Speaker 1: at night, worried about whether you will survive, and the 293 00:13:57,800 --> 00:14:00,640 Speaker 1: things that make you feel like the universe is a comfortable, 294 00:14:00,720 --> 00:14:03,480 Speaker 1: cozy place. It's all set up for you to have 295 00:14:03,520 --> 00:14:05,920 Speaker 1: a good time. We talk about black holes, we talk 296 00:14:05,920 --> 00:14:08,040 Speaker 1: about quarks. We talk about the future of the human 297 00:14:08,120 --> 00:14:09,240 Speaker 1: race and whether it. 298 00:14:09,280 --> 00:14:11,040 Speaker 2: Has a future or not. 299 00:14:11,520 --> 00:14:12,160 Speaker 7: Dark stuff. 300 00:14:13,360 --> 00:14:15,880 Speaker 1: My friend and co host Orge can't be here today, 301 00:14:15,960 --> 00:14:19,040 Speaker 1: so we are joined by Kelly Weenersmith, who is trying 302 00:14:19,040 --> 00:14:21,320 Speaker 1: to teach you things without scaring your children. 303 00:14:21,440 --> 00:14:24,080 Speaker 7: That's right. I feel like maybe I need to defend 304 00:14:24,120 --> 00:14:26,120 Speaker 7: that decision, but I'm just gonna let it go. Sometimes 305 00:14:26,240 --> 00:14:28,320 Speaker 7: kids don't need to be scared. You get to spend 306 00:14:28,320 --> 00:14:30,280 Speaker 7: your whole adulthood being scared about stuff. 307 00:14:30,280 --> 00:14:31,160 Speaker 2: You know you're right. 308 00:14:31,200 --> 00:14:33,080 Speaker 1: And the thing I love about the universe is that 309 00:14:33,120 --> 00:14:35,480 Speaker 1: it doesn't really care about our feelings. 310 00:14:35,800 --> 00:14:36,960 Speaker 2: It's just crazy. 311 00:14:37,040 --> 00:14:40,200 Speaker 1: It's just bonkers. It's just doing its thing. Whether that 312 00:14:40,280 --> 00:14:43,040 Speaker 1: means it's threatening to tear you apart and blow you away, 313 00:14:43,200 --> 00:14:46,560 Speaker 1: or whether it's created this wonderful environment for you to 314 00:14:46,600 --> 00:14:49,000 Speaker 1: relax in and sip your marker Rita while you listen 315 00:14:49,000 --> 00:14:51,600 Speaker 1: to a podcast. The universe doesn't care either way. 316 00:14:51,760 --> 00:14:53,840 Speaker 7: You know, it's really good that you went into physics 317 00:14:53,840 --> 00:14:57,600 Speaker 7: and not like psychiatry or something. And how how are 318 00:14:57,640 --> 00:14:58,760 Speaker 7: your kids turning out? 319 00:14:59,280 --> 00:15:02,320 Speaker 1: My kid's so far are not sociopaths, you know, but hey, 320 00:15:02,440 --> 00:15:04,880 Speaker 1: we need to collect more data. No, My strategy has 321 00:15:04,920 --> 00:15:08,960 Speaker 1: always been to answer their questions honestly, though I will 322 00:15:09,000 --> 00:15:12,760 Speaker 1: admit if their questions bring up something awkward or uncomfortable 323 00:15:12,840 --> 00:15:15,720 Speaker 1: or maybe age inappropriate, I'll try to deflect the question 324 00:15:15,840 --> 00:15:18,200 Speaker 1: once or twice. But if they really insist, if they 325 00:15:18,280 --> 00:15:20,480 Speaker 1: drill in for an answer, I'm giving it to them. 326 00:15:21,280 --> 00:15:23,720 Speaker 1: One of my favorite things on the podcast was getting 327 00:15:23,720 --> 00:15:26,800 Speaker 1: to fan boy out and talk to science fiction authors 328 00:15:27,000 --> 00:15:30,080 Speaker 1: whose work I'd been admiring for years. We got to 329 00:15:30,120 --> 00:15:31,640 Speaker 1: talk to some pretty famous folks. 330 00:15:31,960 --> 00:15:35,520 Speaker 10: I'm an lucky I'm the author, most famously, I guess, 331 00:15:35,560 --> 00:15:39,040 Speaker 10: the author of the novel Ancillary Justice and it sequels 332 00:15:39,040 --> 00:15:44,240 Speaker 10: Ancillary Sword and Ancellary Mercy. My name is Mary robinet Cole. 333 00:15:44,280 --> 00:15:46,960 Speaker 10: I write science fiction and fantasy. I'm also an audiobook 334 00:15:47,040 --> 00:15:48,800 Speaker 10: narrator and a professional puppeteer. 335 00:15:49,040 --> 00:15:50,960 Speaker 1: Well, it's not that often that you made a science 336 00:15:50,960 --> 00:15:54,240 Speaker 1: fiction author who's also a puppeteer. How did those two 337 00:15:54,320 --> 00:15:55,280 Speaker 1: careers intersect. 338 00:15:56,160 --> 00:16:00,240 Speaker 10: They're both all about theater of the possible. Anything is 339 00:16:00,280 --> 00:16:03,600 Speaker 10: possible when you step into popetry or science fiction, so 340 00:16:03,840 --> 00:16:07,400 Speaker 10: they're both also, I think, places that tend to naturally 341 00:16:07,440 --> 00:16:09,480 Speaker 10: explore what if in imagination. 342 00:16:10,960 --> 00:16:13,720 Speaker 1: It's my great pleasure to welcome to the podcast. Peter Harness, 343 00:16:13,720 --> 00:16:17,320 Speaker 1: an English playwright, screenwriter and actor. Thanks very much for 344 00:16:17,440 --> 00:16:17,920 Speaker 1: joining us. 345 00:16:18,120 --> 00:16:19,000 Speaker 4: Thank you very much. 346 00:16:19,080 --> 00:16:20,400 Speaker 2: I need to update Wikipedia. 347 00:16:20,520 --> 00:16:22,480 Speaker 4: I haven't done any acting for a very long time, 348 00:16:22,480 --> 00:16:23,040 Speaker 4: but it's nice. 349 00:16:23,080 --> 00:16:25,960 Speaker 2: It's still it's nice. It still believes that I have 350 00:16:26,160 --> 00:16:28,840 Speaker 2: more Once an actor, always an actor. 351 00:16:29,320 --> 00:16:32,880 Speaker 1: We also reached out to top physicists and science communicators 352 00:16:32,920 --> 00:16:35,440 Speaker 1: to come talk to us about their ideas about the 353 00:16:35,480 --> 00:16:39,480 Speaker 1: most confusing and mysterious theories in physics. Here's a clip 354 00:16:39,520 --> 00:16:43,160 Speaker 1: from my conversation with Sean Carroll. So it's my great 355 00:16:43,160 --> 00:16:47,080 Speaker 1: pleasure to introduce Professor Sean Carroll. He's a theoretical physicist 356 00:16:47,160 --> 00:16:50,240 Speaker 1: at Caltech, and he's known for his work on cosmology, 357 00:16:50,480 --> 00:16:53,760 Speaker 1: general relativity, and the foundations of quantum mechanics. He's also 358 00:16:53,840 --> 00:16:56,920 Speaker 1: the author of several widely acclaimed and widely read books, 359 00:16:57,000 --> 00:17:00,240 Speaker 1: including Something Deeply Hidden and The Big Picture, and is 360 00:17:00,240 --> 00:17:03,360 Speaker 1: the host of the podcast Mindscape, which might actually be 361 00:17:03,480 --> 00:17:06,160 Speaker 1: neardier than this podcast. Today, Sean is here to talk 362 00:17:06,200 --> 00:17:08,920 Speaker 1: to us about the many world's interpretation of quantum mechanics 363 00:17:08,960 --> 00:17:12,080 Speaker 1: and the measurement problem in quantum mechanics. Sean, Welcome to 364 00:17:12,080 --> 00:17:14,040 Speaker 1: the podcast. Thanks very much for having me here. 365 00:17:14,200 --> 00:17:15,080 Speaker 2: Wonderful to have you. 366 00:17:15,440 --> 00:17:17,639 Speaker 1: So I want to dive right in and before we 367 00:17:17,680 --> 00:17:20,440 Speaker 1: talk about what the many world's interpretation is, I want 368 00:17:20,440 --> 00:17:23,480 Speaker 1: to get your view on what problem it solves, like, 369 00:17:23,520 --> 00:17:26,080 Speaker 1: why do we need so many interpretations of quantum mechanics? 370 00:17:26,080 --> 00:17:28,200 Speaker 1: What problem is it that they are trying to address. 371 00:17:28,400 --> 00:17:30,280 Speaker 3: I think there's actually two problems. I mean, this is 372 00:17:30,280 --> 00:17:32,640 Speaker 3: the right question, because are we just wasting our time 373 00:17:32,760 --> 00:17:34,960 Speaker 3: or honestly, it's not a lot of time compared to 374 00:17:35,000 --> 00:17:37,560 Speaker 3: other physicists thinking about other things. The foundations of quantum 375 00:17:37,600 --> 00:17:39,840 Speaker 3: mechanics is a minority pursuit. But I think there are 376 00:17:39,840 --> 00:17:44,679 Speaker 3: two problems, and they're such looming, large problems, and quantum 377 00:17:44,680 --> 00:17:48,080 Speaker 3: mechanics is so important to modern physics that I do 378 00:17:48,160 --> 00:17:49,880 Speaker 3: wish we were spending more time on them. 379 00:17:50,160 --> 00:17:52,920 Speaker 1: And I got to talk to Carlo Ravelli. So it's 380 00:17:52,920 --> 00:17:56,280 Speaker 1: my great pleasure today to introduce Professor Carlo Rovelli. He's 381 00:17:56,320 --> 00:17:58,600 Speaker 1: a professor of physics in Marseille, and he cut his 382 00:17:58,640 --> 00:18:01,119 Speaker 1: teeth and made his name for himself developing theories of 383 00:18:01,240 --> 00:18:04,720 Speaker 1: quantum gravity, mostly loop quantum gravity, if I understand correctly. 384 00:18:05,080 --> 00:18:07,119 Speaker 1: He also became a household name as the author of 385 00:18:07,119 --> 00:18:09,679 Speaker 1: the book Seven brief Lessons on Physics, which sold more 386 00:18:09,720 --> 00:18:13,080 Speaker 1: than a million copies and was translated into forty one languages. 387 00:18:13,359 --> 00:18:15,880 Speaker 1: I've read it and enjoyed it immensely and heartily recommended 388 00:18:15,920 --> 00:18:17,840 Speaker 1: to you. Today, Professor Revelli is here to talk to 389 00:18:17,960 --> 00:18:20,400 Speaker 1: us about his new book, Hell Go Land and a 390 00:18:20,440 --> 00:18:24,640 Speaker 1: fascinating alternative take on the measurement problem in quantum mechanics. 391 00:18:24,640 --> 00:18:27,119 Speaker 1: Professor Velli, welcome to the podcast and thank you for 392 00:18:27,240 --> 00:18:27,760 Speaker 1: joining us. 393 00:18:27,880 --> 00:18:30,240 Speaker 4: Thank you very much, Dadiel. It's a pleasure in honor 394 00:18:30,240 --> 00:18:30,760 Speaker 4: of being here. 395 00:18:31,280 --> 00:18:31,800 Speaker 2: Wonderful. 396 00:18:32,160 --> 00:18:35,600 Speaker 1: Well, I always love talking about quantum mechanics and puzzling 397 00:18:35,680 --> 00:18:37,400 Speaker 1: over it with other people. I feel like every time 398 00:18:37,440 --> 00:18:39,960 Speaker 1: I talk about quantum mechanics with somebody else, I think 399 00:18:39,960 --> 00:18:42,600 Speaker 1: of a new question I've never thought of before, or 400 00:18:42,640 --> 00:18:45,000 Speaker 1: a new angle on it, or a new mystery. Frankly, 401 00:18:45,040 --> 00:18:47,480 Speaker 1: like a new corner of my mind that I haven't 402 00:18:47,520 --> 00:18:50,080 Speaker 1: ever really examined, and I get confused, and so it's 403 00:18:50,080 --> 00:18:51,960 Speaker 1: always fun to figure things outsie of on the fly. 404 00:18:52,359 --> 00:18:54,560 Speaker 1: So today we wanted to talk about your new book 405 00:18:54,680 --> 00:18:57,560 Speaker 1: and Hell Go Land, and the book essentially lays out 406 00:18:57,600 --> 00:19:01,679 Speaker 1: for a lay audience this idea of relational quantum mechanics, 407 00:19:01,920 --> 00:19:04,639 Speaker 1: sort of a new interpretation on quantum mechanics. And the 408 00:19:04,640 --> 00:19:07,120 Speaker 1: first question for you I have is if you could 409 00:19:07,160 --> 00:19:10,840 Speaker 1: describe for us what is the problem that relational quantum 410 00:19:10,880 --> 00:19:14,840 Speaker 1: mechanics solves, Like why do we need another quantum mechanics interpretation. 411 00:19:15,320 --> 00:19:18,240 Speaker 1: What is it at the heart of relitional quant mechanics 412 00:19:18,280 --> 00:19:19,760 Speaker 1: is trying to do One of. 413 00:19:19,720 --> 00:19:22,760 Speaker 3: The difficulties of the problem of quantum mechanics is to 414 00:19:22,800 --> 00:19:24,280 Speaker 3: say exactly what the problem is. 415 00:19:24,520 --> 00:19:26,480 Speaker 1: Those are some of my favorite moments of the show, 416 00:19:26,560 --> 00:19:29,199 Speaker 1: but there are so so many, way too many to 417 00:19:29,280 --> 00:19:31,520 Speaker 1: mention here, and so I encourage you to go back 418 00:19:31,520 --> 00:19:33,879 Speaker 1: and listen to old episodes because there's a lot of 419 00:19:33,920 --> 00:19:36,520 Speaker 1: great stuff there. And also the show isn't just me, 420 00:19:36,600 --> 00:19:39,280 Speaker 1: of course, so I asked all the co hosts we've 421 00:19:39,280 --> 00:19:41,960 Speaker 1: had over the years to share their thoughts on their 422 00:19:42,119 --> 00:19:44,480 Speaker 1: favorite moments. Here's what I heard back. 423 00:19:44,720 --> 00:19:48,720 Speaker 6: I want to say that I really appreciate being on 424 00:19:48,760 --> 00:19:50,639 Speaker 6: the show, being able to be a part of it, 425 00:19:50,760 --> 00:19:56,520 Speaker 6: despite not having any any prior knowledge really about particle physics. 426 00:19:56,560 --> 00:19:59,920 Speaker 6: It was really really fun to come on and learn 427 00:20:00,320 --> 00:20:03,280 Speaker 6: and ask questions, and I always felt sort of like 428 00:20:03,400 --> 00:20:06,120 Speaker 6: I was there with you guys the audience trying. I mean, 429 00:20:06,440 --> 00:20:09,680 Speaker 6: probably a lot of you know more about particle physics 430 00:20:09,720 --> 00:20:11,880 Speaker 6: than me, but still I would try to be there 431 00:20:12,200 --> 00:20:14,880 Speaker 6: as the stand in for the audience, try to ask 432 00:20:14,920 --> 00:20:17,160 Speaker 6: the questions that I was hoping you guys would want 433 00:20:17,160 --> 00:20:20,440 Speaker 6: me to ask of Daniel and man, I just had 434 00:20:20,480 --> 00:20:24,520 Speaker 6: such a good time, and I really appreciate all the 435 00:20:24,880 --> 00:20:29,000 Speaker 6: love and support from you guys, and I I'm so 436 00:20:29,080 --> 00:20:32,200 Speaker 6: happy I got to be a part of this amazing podcast. 437 00:20:32,440 --> 00:20:37,199 Speaker 6: And I hope y'all continue to learn and continue to 438 00:20:37,240 --> 00:20:42,840 Speaker 6: be physicists and scientists in your own homes and keep 439 00:20:42,880 --> 00:20:46,080 Speaker 6: asking really cool questions. 440 00:20:46,320 --> 00:20:47,879 Speaker 7: I had a lot of fun on a lot of 441 00:20:47,880 --> 00:20:51,920 Speaker 7: the episodes. One of the episodes I particularly liked was 442 00:20:51,960 --> 00:20:55,840 Speaker 7: when we talked about how physics might help us understand 443 00:20:56,000 --> 00:21:00,720 Speaker 7: biology better. That was an episode that to me thinking 444 00:21:00,840 --> 00:21:02,800 Speaker 7: long after our conversation ended. 445 00:21:03,160 --> 00:21:05,399 Speaker 1: So we've had fun, and I hope that you've learned 446 00:21:05,400 --> 00:21:07,880 Speaker 1: a lot of physics along the way. But I want 447 00:21:07,920 --> 00:21:09,879 Speaker 1: you to understand that it's not just all of you 448 00:21:10,320 --> 00:21:11,760 Speaker 1: who've learned a bunch of science. 449 00:21:12,080 --> 00:21:14,879 Speaker 2: I have to you. See, physics is way. 450 00:21:14,680 --> 00:21:17,919 Speaker 1: Too vast for any one person to understand all of 451 00:21:17,920 --> 00:21:20,879 Speaker 1: it or even have time to try. So there are 452 00:21:20,880 --> 00:21:23,680 Speaker 1: always things I wanted to know more about, and as 453 00:21:23,680 --> 00:21:27,720 Speaker 1: I became more and more specialized in experimental particle physics, 454 00:21:27,960 --> 00:21:31,879 Speaker 1: I felt myself lacking those opportunities, but still asking the questions, 455 00:21:32,200 --> 00:21:34,440 Speaker 1: how do galaxies form, how do we know what's going 456 00:21:34,480 --> 00:21:38,520 Speaker 1: on inside stars? Do we know what's going on inside stars? 457 00:21:38,760 --> 00:21:41,600 Speaker 1: And so the podcast was a great excuse to go 458 00:21:41,680 --> 00:21:44,520 Speaker 1: and learn about these things, a reason to spend an 459 00:21:44,560 --> 00:21:48,040 Speaker 1: hour reading up on the latest research on intergalactic magnetic 460 00:21:48,040 --> 00:21:50,800 Speaker 1: fields or whatever the topic was that week. It also 461 00:21:50,880 --> 00:21:54,560 Speaker 1: helped me understand particle physics, because yeah, I certainly learned 462 00:21:54,600 --> 00:21:57,120 Speaker 1: all this stuff at one point, but you really have 463 00:21:57,200 --> 00:21:59,879 Speaker 1: to understand everything and have a click in your mind 464 00:22:00,160 --> 00:22:02,320 Speaker 1: if you're going to explain it to non experts and 465 00:22:02,440 --> 00:22:05,600 Speaker 1: answer top questions from our co hosts. So I asked 466 00:22:05,600 --> 00:22:08,400 Speaker 1: our co hosts what this experience was like for them 467 00:22:08,600 --> 00:22:11,800 Speaker 1: and whether they had any farewell messages for all of you. 468 00:22:12,480 --> 00:22:16,480 Speaker 6: Here's what I heard back, Hey, this is Katie Golden. 469 00:22:16,840 --> 00:22:21,800 Speaker 6: My favorite topic was the episode on which forces power 470 00:22:21,880 --> 00:22:25,480 Speaker 6: the human senses, which for me was a perfect mix 471 00:22:25,800 --> 00:22:31,240 Speaker 6: of biology and physics. I love looking into the physics 472 00:22:31,359 --> 00:22:36,080 Speaker 6: that are behind our biological functioning like our vision, our hearing, 473 00:22:36,160 --> 00:22:38,960 Speaker 6: and also getting into some of the cool evolutionary biology 474 00:22:38,960 --> 00:22:44,520 Speaker 6: stuff of electromagnetism and how animals can sort of sense 475 00:22:44,680 --> 00:22:48,399 Speaker 6: like electromagnetism. And it was really really fun I enjoyed 476 00:22:48,480 --> 00:22:51,320 Speaker 6: kind of having that merging of my pet interest being 477 00:22:51,359 --> 00:22:54,800 Speaker 6: evolutionary biology and then learning about all of the cool 478 00:22:54,840 --> 00:22:58,679 Speaker 6: physics behind it from Daniel. I guess the most challenging 479 00:22:58,760 --> 00:23:02,439 Speaker 6: topic for me has been and continues to be trying 480 00:23:02,480 --> 00:23:08,119 Speaker 6: to visualize or understand gravity, understanding it is not a force, 481 00:23:08,560 --> 00:23:12,199 Speaker 6: and sort of also the idea that it is like 482 00:23:12,280 --> 00:23:16,639 Speaker 6: the curvature in space, but also that space isn't like 483 00:23:16,680 --> 00:23:20,600 Speaker 6: a physical fabric that bends. I still can't really wrap 484 00:23:20,640 --> 00:23:23,560 Speaker 6: my head around it. It's pretty difficult, and I'm sure 485 00:23:23,560 --> 00:23:26,680 Speaker 6: I'm not alone in that, But I despite it being 486 00:23:26,680 --> 00:23:29,399 Speaker 6: really challenging for me to understand or visualize or have 487 00:23:29,520 --> 00:23:33,760 Speaker 6: like a concept of, it's still really infinitely fascinating to me. 488 00:23:34,119 --> 00:23:37,960 Speaker 6: And my favorite moments on air definitely every time Daniel 489 00:23:38,240 --> 00:23:42,439 Speaker 6: would make some comparison between food and particle physics. I 490 00:23:42,720 --> 00:23:45,360 Speaker 6: feel like part of that was because we would often 491 00:23:45,400 --> 00:23:50,720 Speaker 6: record sometimes like for me, like before dinner, and you 492 00:23:50,760 --> 00:23:56,400 Speaker 6: would definitely make me hungry talking about spaghetification into black holes. 493 00:23:56,880 --> 00:23:58,800 Speaker 6: We also recently I don't know if this will be 494 00:23:58,800 --> 00:24:01,119 Speaker 6: out yet, so I'll try not to do any spoilers, 495 00:24:01,119 --> 00:24:04,040 Speaker 6: but we also recently did a listener question episode about 496 00:24:04,080 --> 00:24:07,520 Speaker 6: the warp drive in Star Trek, and I loved talking 497 00:24:07,560 --> 00:24:13,280 Speaker 6: about the fake sciencey schmayancy stuff in Star Trek, like 498 00:24:13,320 --> 00:24:15,840 Speaker 6: the science gibbers that they would talk about, like the 499 00:24:15,880 --> 00:24:20,560 Speaker 6: flux capacitors, et cetera. Also, I don't want to spoil 500 00:24:20,640 --> 00:24:22,560 Speaker 6: it the episode in case it's not out yet, but 501 00:24:23,560 --> 00:24:26,840 Speaker 6: there's a moment in it when my mind is completely 502 00:24:26,880 --> 00:24:31,520 Speaker 6: blown by sort of what would happen in reality in 503 00:24:31,560 --> 00:24:36,280 Speaker 6: a situation with warp drive, And you can probably tell 504 00:24:36,280 --> 00:24:38,639 Speaker 6: what it is because I don't know. I think I 505 00:24:38,720 --> 00:24:39,680 Speaker 6: sound pretty excited. 506 00:24:41,800 --> 00:24:45,359 Speaker 7: Hello, this is Kelly Wiener Smith. So to be honest, 507 00:24:45,359 --> 00:24:49,879 Speaker 7: I found a lot of the topics kind of challenging. So, 508 00:24:50,280 --> 00:24:53,000 Speaker 7: you know, talking to a particle physicist as someone who 509 00:24:53,040 --> 00:24:57,639 Speaker 7: has absolutely no training in that area and knowing that 510 00:24:57,680 --> 00:25:01,760 Speaker 7: there's an audience listening to my responses, you know, it's 511 00:25:01,760 --> 00:25:05,000 Speaker 7: a bit of a humbling experience. And quite often before 512 00:25:05,040 --> 00:25:07,560 Speaker 7: I'd ask a question, I'd find myself thinking, oh, is 513 00:25:07,560 --> 00:25:10,240 Speaker 7: this a bad question? Does everyone know the answer to 514 00:25:10,280 --> 00:25:14,399 Speaker 7: this question already? But you know, my job was to 515 00:25:14,880 --> 00:25:17,640 Speaker 7: play the you know, the everyman or the every person 516 00:25:18,280 --> 00:25:21,080 Speaker 7: and ask whatever was on my mind or whatever. I 517 00:25:21,119 --> 00:25:24,600 Speaker 7: didn't think I was understanding quite well enough. So I 518 00:25:24,680 --> 00:25:27,240 Speaker 7: got over it and it was fun and I enjoyed 519 00:25:27,280 --> 00:25:29,640 Speaker 7: the challenge and I learned a lot by going through 520 00:25:29,640 --> 00:25:33,400 Speaker 7: these conversations with Daniel. I really enjoyed the running joke 521 00:25:33,480 --> 00:25:36,479 Speaker 7: that we had about how Daniel was always bringing up 522 00:25:36,560 --> 00:25:39,600 Speaker 7: questions about how my kids might die or how you know, 523 00:25:39,720 --> 00:25:42,280 Speaker 7: everybody might die, and how I couldn't let my kids 524 00:25:42,320 --> 00:25:45,280 Speaker 7: listen to the podcast because they would be petrified and 525 00:25:45,280 --> 00:25:48,160 Speaker 7: wouldn't be able to sleep at night. That was kind 526 00:25:48,160 --> 00:25:52,320 Speaker 7: of a fun running bit. And there was an episode 527 00:25:52,720 --> 00:25:57,080 Speaker 7: we recorded about uranus that it made me giggle quite 528 00:25:57,119 --> 00:25:59,120 Speaker 7: a bit because I have the heart of a twelve 529 00:25:59,200 --> 00:26:02,119 Speaker 7: year old. It has been so much fun, and I 530 00:26:02,240 --> 00:26:04,720 Speaker 7: learned so much by getting to come on and co 531 00:26:04,840 --> 00:26:07,560 Speaker 7: host every once in a while, and I really appreciate 532 00:26:07,600 --> 00:26:09,680 Speaker 7: the opportunity. Thanks everyone, But. 533 00:26:09,640 --> 00:26:11,919 Speaker 1: The podcast is much more than just me and the 534 00:26:11,960 --> 00:26:14,560 Speaker 1: co hosts. It wouldn't be what it is without all 535 00:26:14,600 --> 00:26:18,080 Speaker 1: of you out there listening and supporting it. And over 536 00:26:18,119 --> 00:26:20,080 Speaker 1: the years, I've heard a lot about how the podcast 537 00:26:20,080 --> 00:26:23,040 Speaker 1: has helped you or taught you something. A few listeners 538 00:26:23,119 --> 00:26:25,560 Speaker 1: sent in their thoughts about what they have learned and 539 00:26:25,600 --> 00:26:28,560 Speaker 1: the role of the podcast has played in their lives. 540 00:26:29,160 --> 00:26:32,720 Speaker 8: Hi, Daniel, your podcast has helped me to understand the 541 00:26:32,800 --> 00:26:35,920 Speaker 8: universe to a depth where I can start formulating an 542 00:26:35,960 --> 00:26:41,280 Speaker 8: intellectual and emotional connection to the cosmos on the grandest 543 00:26:41,400 --> 00:26:45,840 Speaker 8: or largest scale and the smallest or quantum scale. I 544 00:26:45,920 --> 00:26:48,720 Speaker 8: tried to express this in a painting I made recently 545 00:26:49,520 --> 00:26:53,960 Speaker 8: in which I learned two facts and combine them on 546 00:26:54,080 --> 00:26:58,280 Speaker 8: the painting. One was that fungal mycelium has a filamentous 547 00:26:58,320 --> 00:27:01,360 Speaker 8: network structure, and the other was something I learned from 548 00:27:01,400 --> 00:27:05,679 Speaker 8: your podcast that said, in which you told us that 549 00:27:05,800 --> 00:27:10,440 Speaker 8: galaxies in the universe form chains called galactic filaments that 550 00:27:10,560 --> 00:27:15,240 Speaker 8: connect groups and clusters of galaxies. These sorts of repeating 551 00:27:15,359 --> 00:27:19,439 Speaker 8: patterns in nature have always fascinated me, and to find 552 00:27:19,600 --> 00:27:23,760 Speaker 8: that the filamentous pattern of my celium is also found 553 00:27:23,760 --> 00:27:28,040 Speaker 8: at the largest scales of the universe just fills me 554 00:27:28,119 --> 00:27:33,840 Speaker 8: with awe. Thank you again, Daniel for sharing your knowledge 555 00:27:34,040 --> 00:27:37,399 Speaker 8: and understanding with the world through your podcast. 556 00:27:39,960 --> 00:27:45,560 Speaker 11: I enjoyed learning about how space expands because that kind 557 00:27:45,600 --> 00:27:49,560 Speaker 11: of stuff just blows my mind. Mostly, I enjoy the 558 00:27:49,640 --> 00:27:53,400 Speaker 11: podcast in general and learning about all these new things 559 00:27:54,000 --> 00:27:57,920 Speaker 11: that you've introduced to me because my friends are idiots 560 00:27:58,280 --> 00:27:59,520 Speaker 11: and I have no one to talk to. 561 00:28:01,920 --> 00:28:06,280 Speaker 9: Hello, Daniel and Hora, this is Walt from Tennessee. I've 562 00:28:06,359 --> 00:28:09,479 Speaker 9: learned a lot from listening to your podcast, but the 563 00:28:09,480 --> 00:28:13,520 Speaker 9: most significant item that I've learned is the realization of 564 00:28:13,560 --> 00:28:16,920 Speaker 9: how far we are from the ultimate knowledge of how 565 00:28:16,920 --> 00:28:22,119 Speaker 9: the universe really works. Plus, I really enjoy the speculations 566 00:28:22,160 --> 00:28:25,240 Speaker 9: about someday being able to ask aliens for the truth 567 00:28:25,760 --> 00:28:29,520 Speaker 9: after they've been around for millions of years. Unfortunately I 568 00:28:29,560 --> 00:28:30,600 Speaker 9: won't be around for that. 569 00:28:32,800 --> 00:28:35,200 Speaker 12: Once nor I had was on the July twenty fourth 570 00:28:35,200 --> 00:28:40,760 Speaker 12: episode about membranes. Katie said insane in the brain, and 571 00:28:41,200 --> 00:28:44,920 Speaker 12: just like we had planned and rehearsed it on my 572 00:28:45,080 --> 00:28:48,320 Speaker 12: response was insane in the brain, right on top of 573 00:28:48,360 --> 00:28:50,560 Speaker 12: your response. And I did get a little bit of 574 00:28:50,640 --> 00:28:52,520 Speaker 12: laugh out of that, and I'll bet a lot of 575 00:28:52,560 --> 00:28:54,960 Speaker 12: us had the same reaction, at least for those that 576 00:28:55,000 --> 00:28:59,560 Speaker 12: remember those older times. I do roll my eyes at 577 00:28:59,600 --> 00:29:02,080 Speaker 12: some of the in the beginning of the show between 578 00:29:02,120 --> 00:29:05,200 Speaker 12: you and Jorge, but it's still a good portion of 579 00:29:05,240 --> 00:29:09,040 Speaker 12: the show. Another thing I look forward to is listener questions, 580 00:29:09,320 --> 00:29:11,080 Speaker 12: especially the younger kids. 581 00:29:11,960 --> 00:29:12,560 Speaker 11: I love. 582 00:29:12,840 --> 00:29:16,480 Speaker 12: I love to hear younger kids asking, you know, questions 583 00:29:16,480 --> 00:29:18,120 Speaker 12: that you know I may know a lot more about 584 00:29:18,160 --> 00:29:20,560 Speaker 12: than them, but still it tells me that they're asking 585 00:29:20,600 --> 00:29:23,400 Speaker 12: and interested and you provoke those questions. So I think 586 00:29:23,400 --> 00:29:27,479 Speaker 12: that's great. Katie and Kelly are very nice additions, and 587 00:29:27,520 --> 00:29:31,840 Speaker 12: they add a lot more humor with their perspectives. Some 588 00:29:31,880 --> 00:29:34,480 Speaker 12: of my favorite episodes I love anything to do with 589 00:29:34,520 --> 00:29:36,760 Speaker 12: the sun. I love how the sun works and I 590 00:29:36,840 --> 00:29:40,000 Speaker 12: love to learn more about it. Some of the episodes 591 00:29:40,040 --> 00:29:44,080 Speaker 12: that leave my eyes glazing glazing over are the any 592 00:29:44,120 --> 00:29:48,760 Speaker 12: any any podcasts dealing with particles? I just I just 593 00:29:48,800 --> 00:29:52,960 Speaker 12: don't get it, but I still listen to them all, 594 00:29:53,040 --> 00:29:55,120 Speaker 12: and I listened, and I also look forward to listening 595 00:29:55,120 --> 00:29:58,200 Speaker 12: to the next one. Thanks for letting me play a 596 00:29:58,280 --> 00:30:02,480 Speaker 12: small part, not quite as small as your portion of 597 00:30:02,480 --> 00:30:03,920 Speaker 12: the Nobel Prize you want. 598 00:30:05,920 --> 00:30:09,280 Speaker 4: Daniel Johy, I'd just like to thank you onward from Australia. 599 00:30:09,280 --> 00:30:12,560 Speaker 4: I'd just like to thank you both for satisfying my 600 00:30:13,520 --> 00:30:18,720 Speaker 4: quest for knowledge and trying to help me understand quantum physics, 601 00:30:19,080 --> 00:30:23,560 Speaker 4: which is challenging for me. But I really appreciate what 602 00:30:23,600 --> 00:30:25,560 Speaker 4: you to do and you have a perfect balance. 603 00:30:26,000 --> 00:30:30,000 Speaker 13: Thank you so I remember the first episode that I 604 00:30:30,040 --> 00:30:33,600 Speaker 13: have ever heard, and it was very special for me 605 00:30:34,040 --> 00:30:40,640 Speaker 13: because it just make me laugh and I learned something new, 606 00:30:41,360 --> 00:30:44,280 Speaker 13: which was something that didn't happen for me for a 607 00:30:44,320 --> 00:30:48,200 Speaker 13: couple of months after I had a baby and I 608 00:30:48,240 --> 00:30:53,239 Speaker 13: was just struggling to find myself again, and after I 609 00:30:53,320 --> 00:30:57,520 Speaker 13: heard that episode that it was about the Gluons, every 610 00:30:57,600 --> 00:31:02,800 Speaker 13: day I would listen to at least four episodes while 611 00:31:02,920 --> 00:31:07,480 Speaker 13: I was taking care of my baby, and that helped 612 00:31:07,560 --> 00:31:13,880 Speaker 13: me so much, especially not to feel alone. So thank 613 00:31:13,920 --> 00:31:14,560 Speaker 13: you very much. 614 00:31:16,520 --> 00:31:18,560 Speaker 14: This is Eric from Idaho. I just wanted to let 615 00:31:18,560 --> 00:31:20,840 Speaker 14: you know that I discovered your show back in February 616 00:31:21,040 --> 00:31:23,640 Speaker 14: and from the very first episode, I was hooked for 617 00:31:23,800 --> 00:31:26,560 Speaker 14: four straight months. All he did was listen to every 618 00:31:26,640 --> 00:31:29,760 Speaker 14: single episode. My kids are way into it as well. 619 00:31:30,160 --> 00:31:32,840 Speaker 14: My son gave the best compliment I believe. He said, Dad, 620 00:31:33,400 --> 00:31:35,760 Speaker 14: I love Daniel and Jorge. They are just a couple 621 00:31:35,760 --> 00:31:38,800 Speaker 14: of dads sitting around talking about science and making some 622 00:31:38,880 --> 00:31:42,160 Speaker 14: dad jokes. I'm grateful for what you guys do and 623 00:31:42,320 --> 00:31:44,440 Speaker 14: look forward to another six hundred episodes. 624 00:31:46,200 --> 00:31:50,000 Speaker 15: Hi, Daniel and Hooge and Katie and Kelly as well. 625 00:31:51,000 --> 00:31:54,240 Speaker 15: My favorite moments are when you guys entered a discussion 626 00:31:54,320 --> 00:31:58,880 Speaker 15: about the reality behind the physical theories. It's very important 627 00:31:58,920 --> 00:32:01,960 Speaker 15: to me because it too reminds me that although being 628 00:32:02,040 --> 00:32:05,280 Speaker 15: the best tools and methods we have to predict and 629 00:32:05,400 --> 00:32:09,880 Speaker 15: manipulate nature, they are not an exact description of what 630 00:32:10,000 --> 00:32:13,520 Speaker 15: it really is. I deeply believe in science as one 631 00:32:13,560 --> 00:32:16,920 Speaker 15: of the best ways to understand and solve problems, but 632 00:32:17,200 --> 00:32:20,560 Speaker 15: knowing it has its limitations is also important not to 633 00:32:20,600 --> 00:32:24,960 Speaker 15: turn it into a under idealized or flawless or an 634 00:32:25,080 --> 00:32:30,200 Speaker 15: unbiased institution. During the COVID nineteen pandemic, for example, it 635 00:32:30,280 --> 00:32:34,720 Speaker 15: became very important to understand these limitations in a world 636 00:32:34,760 --> 00:32:39,440 Speaker 15: that was craving for information but also generating lots of disinformation. 637 00:32:40,600 --> 00:32:43,600 Speaker 15: Congratulations on a huge podcast you have. I hope it 638 00:32:43,680 --> 00:32:48,920 Speaker 15: becomes so big it turns into a black hole someday. 639 00:32:50,000 --> 00:32:56,160 Speaker 16: This podcast as a quite an important role for me 640 00:32:57,240 --> 00:33:02,280 Speaker 16: because it makes commuting bara. It is one of the 641 00:33:02,360 --> 00:33:08,400 Speaker 16: few good podcasts that get updated twice a week most 642 00:33:08,440 --> 00:33:15,600 Speaker 16: of the time, and therefore helps me bearing driving my car. 643 00:33:16,640 --> 00:33:20,800 Speaker 16: I very much like the possibility to chat with Daniel 644 00:33:21,280 --> 00:33:27,440 Speaker 16: about some physics topics I struggle to understand and have 645 00:33:27,560 --> 00:33:34,200 Speaker 16: someone who wants to share his thoughts and is willing 646 00:33:34,240 --> 00:33:42,360 Speaker 16: to listen to my thoughts about debatable topics. And it's 647 00:33:42,360 --> 00:33:46,320 Speaker 16: hard to find somebody like that. So this is a 648 00:33:46,400 --> 00:33:52,320 Speaker 16: great plus of this podcast. For example, our exchange about 649 00:33:52,320 --> 00:33:58,640 Speaker 16: the many worlds of interpretation and related topics, and also 650 00:33:58,760 --> 00:34:05,400 Speaker 16: so horus commentaries on all the topics are very entertaining. 651 00:34:06,320 --> 00:34:10,560 Speaker 16: By the way, we need more PhD comics, and so 652 00:34:11,360 --> 00:34:16,440 Speaker 16: this podcast is one of the foundations of my spare 653 00:34:16,480 --> 00:34:17,400 Speaker 16: time entertainment. 654 00:34:19,160 --> 00:34:22,520 Speaker 2: Hi, Daniel Norge. This is Dan from Vienna, Virginia. Here. 655 00:34:23,080 --> 00:34:25,120 Speaker 17: I've been with you guys since the beginning. At the 656 00:34:25,160 --> 00:34:27,080 Speaker 17: time I was looking for a new podcast, and this 657 00:34:27,280 --> 00:34:30,600 Speaker 17: just hit the mark. Early on, when Daniel would speak 658 00:34:30,640 --> 00:34:33,200 Speaker 17: of the type of matter that would make up galaxies, planets, 659 00:34:33,239 --> 00:34:36,680 Speaker 17: and people, he would frequently include hamsters. I figured he 660 00:34:36,760 --> 00:34:39,360 Speaker 17: must have owned one, as it's always seemed top of mine. 661 00:34:39,760 --> 00:34:42,640 Speaker 17: Maybe he just finds them cute. I've enjoyed the mind 662 00:34:42,680 --> 00:34:45,680 Speaker 17: bending topics and learning about the largest and smallest parts 663 00:34:45,680 --> 00:34:49,399 Speaker 17: of the universe. Perhaps I've had most interesting, though, were 664 00:34:49,440 --> 00:34:52,760 Speaker 17: the topics that were about those things in our solar 665 00:34:52,800 --> 00:34:54,400 Speaker 17: system that I never knew before. 666 00:34:54,640 --> 00:34:58,360 Speaker 18: Keep up the great work. Ever since I was a 667 00:34:58,400 --> 00:35:02,800 Speaker 18: little kid. It was fascinated astronomy, how the universe works 668 00:35:02,840 --> 00:35:07,480 Speaker 18: from every scale, the smallest to the largest, And once 669 00:35:07,520 --> 00:35:11,840 Speaker 18: I got into higher levels of education, I realized that 670 00:35:11,920 --> 00:35:15,480 Speaker 18: the advanced mathematics was not for me. But I always 671 00:35:15,480 --> 00:35:18,880 Speaker 18: remained an active spectator in the world of science and 672 00:35:18,920 --> 00:35:23,640 Speaker 18: its advancements and everything. In all of that, the challenge 673 00:35:23,680 --> 00:35:27,800 Speaker 18: with modern science reporting is that some of it is 674 00:35:28,480 --> 00:35:33,759 Speaker 18: not great. But once I found my way to this podcast, 675 00:35:34,320 --> 00:35:39,239 Speaker 18: I realized that these concepts may be incredibly complicated in 676 00:35:39,320 --> 00:35:44,680 Speaker 18: the calculation of them, but in actually understanding the premise 677 00:35:44,760 --> 00:35:48,719 Speaker 18: of them. It just needs somebody who can explain it. 678 00:35:48,800 --> 00:35:52,319 Speaker 18: And this podcast has helped do that for me and 679 00:35:52,360 --> 00:35:55,600 Speaker 18: obviously so many others. And while it's always been a 680 00:35:55,680 --> 00:35:58,360 Speaker 18: delight hearing my own voice on the pod trying to 681 00:35:58,400 --> 00:36:03,240 Speaker 18: answer questions poorly, the whole premise of it, the whole 682 00:36:03,400 --> 00:36:10,600 Speaker 18: engagement of a global community all working together to advance curiosity, fascination, 683 00:36:11,000 --> 00:36:13,680 Speaker 18: and understanding in how the world works around us and 684 00:36:13,719 --> 00:36:17,440 Speaker 18: realize we're all kind of closer together than we may think. 685 00:36:17,719 --> 00:36:19,640 Speaker 18: I love it and thank you for doing this. 686 00:36:21,640 --> 00:36:25,520 Speaker 19: I don't know if I have a favorite episode per se. 687 00:36:27,040 --> 00:36:33,759 Speaker 19: But I must say that when the audience participation questions 688 00:36:34,080 --> 00:36:38,840 Speaker 19: were conducted in person and I had an opportunity to 689 00:36:38,880 --> 00:36:43,479 Speaker 19: attend a conference in southern California, I was very, very 690 00:36:43,600 --> 00:36:48,000 Speaker 19: tempted to take a day off the conference proceedings and 691 00:36:48,920 --> 00:36:54,879 Speaker 19: find the UC Irvine campus and look for I don't 692 00:36:54,880 --> 00:36:57,759 Speaker 19: even know what to look for, some sort of what 693 00:36:57,840 --> 00:37:00,920 Speaker 19: I imagined to be a grizzly haired professor serve with a 694 00:37:00,960 --> 00:37:06,600 Speaker 19: microphone and or tape recorder. However, I did not do that, 695 00:37:07,239 --> 00:37:10,360 Speaker 19: And you know, perhaps it's fair to say that the 696 00:37:10,800 --> 00:37:15,160 Speaker 19: silver lining of the pandemic is that it encouraged the 697 00:37:15,320 --> 00:37:18,680 Speaker 19: audience participation to be expanded out into the realms of 698 00:37:18,680 --> 00:37:22,960 Speaker 19: the Internet. And I really enjoy that format, and I 699 00:37:23,000 --> 00:37:27,400 Speaker 19: was very very happy to have one of my listener 700 00:37:27,480 --> 00:37:29,200 Speaker 19: questions even answered on the pod. 701 00:37:30,640 --> 00:37:35,440 Speaker 20: Hi, Daniel and Jorge, congratulations on over six hundred episodes. 702 00:37:36,040 --> 00:37:39,000 Speaker 20: My name is Andrea, and I'm a relatively new fan 703 00:37:39,040 --> 00:37:43,480 Speaker 20: of the podcast. I think what I love most about 704 00:37:43,560 --> 00:37:50,000 Speaker 20: the podcast is how you explain super complex topics in 705 00:37:50,160 --> 00:37:54,200 Speaker 20: a way that is really accessible for people without dumbing 706 00:37:54,200 --> 00:37:57,080 Speaker 20: it down. Though I mean there's a lot of times 707 00:37:57,080 --> 00:38:00,440 Speaker 20: where I find myself having to go and do a 708 00:38:00,440 --> 00:38:05,320 Speaker 20: little digging after listening to your podcasts. But what really 709 00:38:05,440 --> 00:38:09,560 Speaker 20: keeps me coming back is your puerile sense of humor. 710 00:38:10,320 --> 00:38:13,120 Speaker 20: It is pretty funny to have that in the mix. 711 00:38:13,400 --> 00:38:18,960 Speaker 20: And finally, my very favorite part is when Daniel gets 712 00:38:19,080 --> 00:38:24,360 Speaker 20: upset about white chocolate. I never realized how kind of 713 00:38:24,360 --> 00:38:28,440 Speaker 20: pointless white chocolate was until I started listening to your podcast. 714 00:38:29,000 --> 00:38:31,799 Speaker 20: I totally agree. I was wondering if maybe you could 715 00:38:31,800 --> 00:38:36,080 Speaker 20: do a deep dive episode into the science behind and 716 00:38:36,280 --> 00:38:40,880 Speaker 20: history of white chocolate, but if you did, I'd probably 717 00:38:40,880 --> 00:38:43,640 Speaker 20: skip that one, so it might not be a good idea. 718 00:38:44,200 --> 00:38:46,440 Speaker 20: Thanks again for sharing your knowledge. 719 00:38:47,040 --> 00:38:51,680 Speaker 1: Thank you for validating my crusade against white chocolate. If 720 00:38:51,719 --> 00:38:54,319 Speaker 1: I've achieved nothing else on the podcast, I freed one 721 00:38:54,360 --> 00:38:57,600 Speaker 1: more person e from the tyranny of white chocolate, and 722 00:38:57,719 --> 00:38:59,719 Speaker 1: on the topic of the science of white chocolate, there 723 00:38:59,760 --> 00:39:04,240 Speaker 1: is it's scientifically disgusting. I also asked my wife, Katrina, 724 00:39:04,280 --> 00:39:06,440 Speaker 1: who I've referred to many times on the podcast and 725 00:39:06,440 --> 00:39:10,320 Speaker 1: whose voice you've occasionally heard, what she thinks the podcast 726 00:39:10,360 --> 00:39:12,520 Speaker 1: has meant for me and for the family. 727 00:39:12,960 --> 00:39:14,080 Speaker 2: Here's what she had to say. 728 00:39:14,239 --> 00:39:17,880 Speaker 21: Well, I love that Daniel has been doing this podcast. 729 00:39:18,160 --> 00:39:21,239 Speaker 21: I mean, I can't believe how big it's gotten and 730 00:39:21,560 --> 00:39:24,440 Speaker 21: how many episodes they've made. It's just amazing to me 731 00:39:24,840 --> 00:39:28,160 Speaker 21: what a life this thing has taken. And we really love. 732 00:39:28,239 --> 00:39:32,319 Speaker 21: Our family loves hearing the messages from the people on 733 00:39:32,360 --> 00:39:34,840 Speaker 21: the podcast. Like I remember during the pandemic there was 734 00:39:34,880 --> 00:39:38,120 Speaker 21: this group of housemates in Australia who were hilarious and 735 00:39:38,160 --> 00:39:40,080 Speaker 21: they sent in all these messages where they were having 736 00:39:40,080 --> 00:39:42,279 Speaker 21: fun together and listening to music and we were all, 737 00:39:42,760 --> 00:39:45,240 Speaker 21: you know, alone in our house and it was so fun. 738 00:39:45,600 --> 00:39:50,680 Speaker 21: All that interjected into our lives. And yeah, I just 739 00:39:50,800 --> 00:39:52,719 Speaker 21: I love that there are so many listeners and that 740 00:39:52,760 --> 00:39:55,600 Speaker 21: it's really impacted people's lives. I've heard stories about people 741 00:39:55,640 --> 00:39:59,359 Speaker 21: going back to school, or people you know, using this 742 00:39:59,400 --> 00:40:02,920 Speaker 21: as companion chip. And then even in our own family, 743 00:40:03,000 --> 00:40:05,319 Speaker 21: when our kids couldn't fall asleep, I would often play 744 00:40:05,400 --> 00:40:07,880 Speaker 21: Daniel's podcast so they could get to hear his voice, 745 00:40:08,560 --> 00:40:10,839 Speaker 21: and it is really comforting. I love that we can 746 00:40:10,880 --> 00:40:12,759 Speaker 21: hear his voice on command and get to hear his 747 00:40:12,840 --> 00:40:14,879 Speaker 21: fun sense of humor. In fact, some of our really 748 00:40:14,920 --> 00:40:17,520 Speaker 21: good friends were backpacking on the JMT this summer and 749 00:40:17,560 --> 00:40:20,279 Speaker 21: they were listening to Daniel's podcast at night, but they 750 00:40:20,280 --> 00:40:22,080 Speaker 21: said it was not to fall asleep and that they 751 00:40:22,120 --> 00:40:25,800 Speaker 21: loved learning about Unfortunately I don't remember, but I'm sure. 752 00:40:25,600 --> 00:40:26,960 Speaker 8: They do, and. 753 00:40:28,480 --> 00:40:31,360 Speaker 21: That was really fun. Also, every time I see Starbucks 754 00:40:31,640 --> 00:40:35,560 Speaker 21: n True Cold Brew, I think about Daniel's ad, which 755 00:40:35,600 --> 00:40:38,760 Speaker 21: is also funny. And we've had people send us amazing things, 756 00:40:38,800 --> 00:40:40,520 Speaker 21: like one time we came home on a hot day 757 00:40:40,600 --> 00:40:47,040 Speaker 21: to a box full of beautiful chocolate from Canada. And 758 00:40:47,239 --> 00:40:51,440 Speaker 21: our lab has had a artificial intelligence microwave for several 759 00:40:51,560 --> 00:40:54,239 Speaker 21: years that a listener came and brought it to us 760 00:40:54,480 --> 00:40:56,719 Speaker 21: and showed us how to make salmon and broccoli in 761 00:40:56,719 --> 00:40:59,720 Speaker 21: this beautiful microwave that targets the heat in an evenly 762 00:41:00,280 --> 00:41:06,520 Speaker 21: and directed distributed way. So that was really fun. And 763 00:41:06,960 --> 00:41:09,160 Speaker 21: I just love how much Daniel has learned. You know, 764 00:41:09,200 --> 00:41:12,080 Speaker 21: he's constantly going and talking to his colleagues to learn 765 00:41:12,120 --> 00:41:15,240 Speaker 21: new things. I think it's brought him, you know, really 766 00:41:15,800 --> 00:41:19,879 Speaker 21: huge breadth and depth to his physics knowledge that as 767 00:41:19,920 --> 00:41:22,400 Speaker 21: a researcher you often kind of get lost in your 768 00:41:22,400 --> 00:41:24,640 Speaker 21: own rabbit hole, and I feel like Daniel is really 769 00:41:24,680 --> 00:41:27,799 Speaker 21: not in that position. I'm sure it's been really good 770 00:41:27,800 --> 00:41:30,279 Speaker 21: for his science I think you could ask Daniel to 771 00:41:30,280 --> 00:41:32,480 Speaker 21: give a lecture on any topic in physics and he'd 772 00:41:32,520 --> 00:41:35,480 Speaker 21: have no problem. Like we know this Italian guy who 773 00:41:35,560 --> 00:41:38,960 Speaker 21: was interviewing for a physics professorship, and they would pull 774 00:41:39,000 --> 00:41:40,480 Speaker 21: a topic out of a hat and you'd have to 775 00:41:40,480 --> 00:41:42,239 Speaker 21: give a lecture in front of the department on it 776 00:41:42,280 --> 00:41:45,600 Speaker 21: with no preparation. And that seemed so intimidating to me. 777 00:41:45,640 --> 00:41:47,640 Speaker 21: But I know Daniel could just do that now because 778 00:41:47,680 --> 00:41:48,520 Speaker 21: of this podcast. 779 00:41:49,400 --> 00:41:50,280 Speaker 8: So lately I've. 780 00:41:50,120 --> 00:41:53,719 Speaker 21: Been hearing Daniel brainstorm names for the new podcast, and 781 00:41:53,840 --> 00:41:57,240 Speaker 21: I'm really glad he has a new podcast partner, Kelly. 782 00:41:57,520 --> 00:42:02,320 Speaker 21: I loved her book about the possibility of colonizing Mars, 783 00:42:02,600 --> 00:42:07,440 Speaker 21: and clearly she's a very thoughtful and in depth scientist. 784 00:42:07,719 --> 00:42:07,879 Speaker 8: Oh. 785 00:42:07,920 --> 00:42:10,880 Speaker 21: Another thing that was fun was like we would anytime 786 00:42:10,880 --> 00:42:13,640 Speaker 21: we were in a new place, Daniel would start doing 787 00:42:13,680 --> 00:42:17,600 Speaker 21: his like man on the Street interviews, like airport in Jerusalem, 788 00:42:17,719 --> 00:42:21,600 Speaker 21: Man on Street Interviews Airport in London, asking the locals, 789 00:42:21,640 --> 00:42:23,759 Speaker 21: and then you'd hear the podcast and get to hear 790 00:42:23,800 --> 00:42:28,160 Speaker 21: people with accents from our trip on the podcast. I 791 00:42:28,160 --> 00:42:31,280 Speaker 21: really love that whole aspect, and sometimes, like my students 792 00:42:31,400 --> 00:42:34,080 Speaker 21: or people I knew would get interviewed and then get 793 00:42:34,120 --> 00:42:35,799 Speaker 21: to hear them on the podcast, and I love that. 794 00:42:36,440 --> 00:42:40,080 Speaker 21: So I think it's been a wonderful, wonderful thing. As 795 00:42:40,120 --> 00:42:43,840 Speaker 21: our kids have been growing up, the podcast has happened, 796 00:42:44,080 --> 00:42:47,840 Speaker 21: you know, starting since twenty seventeen, I think maybe twenty eighteen, 797 00:42:47,920 --> 00:42:51,480 Speaker 21: so our kids were like little elementary school kids, and 798 00:42:52,560 --> 00:42:54,959 Speaker 21: they've grown up getting to hear all these stories about 799 00:42:54,960 --> 00:42:58,040 Speaker 21: the podcast. Now they're teenagers, and I think it's been 800 00:42:58,080 --> 00:43:00,520 Speaker 21: a really cool thing to have our family. 801 00:43:01,000 --> 00:43:04,080 Speaker 1: All right, So it's time now to say goodbye to 802 00:43:04,120 --> 00:43:06,759 Speaker 1: this podcast, and I just want to say that it's 803 00:43:06,760 --> 00:43:09,880 Speaker 1: been my pleasure and my honor to host this show 804 00:43:10,000 --> 00:43:12,480 Speaker 1: and to share with you my joy about what we 805 00:43:12,640 --> 00:43:15,160 Speaker 1: have managed to figure out and what we have not 806 00:43:15,360 --> 00:43:18,719 Speaker 1: managed to figure out about the universe, and to anticipate 807 00:43:18,840 --> 00:43:21,719 Speaker 1: all of those discoveries yet to come. And though of 808 00:43:21,760 --> 00:43:24,239 Speaker 1: course this show is coming to an end, you can 809 00:43:24,280 --> 00:43:27,920 Speaker 1: still hear me talking about the universe. So let me 810 00:43:27,960 --> 00:43:30,400 Speaker 1: tell you a little bit about our new show, Daniel 811 00:43:30,440 --> 00:43:32,320 Speaker 1: and Kelly's Extraordinary Universe. 812 00:43:32,520 --> 00:43:34,120 Speaker 2: The official description is that. 813 00:43:34,160 --> 00:43:37,680 Speaker 1: Daniel and Kelly cannot stop talking about our amazing, wonderful, 814 00:43:37,719 --> 00:43:41,120 Speaker 1: weird universe. Each episode is a fun and easy to 815 00:43:41,160 --> 00:43:45,000 Speaker 1: understand explanation of deep topics in science, from particles to 816 00:43:45,120 --> 00:43:48,040 Speaker 1: black holes, to moon colonies, to aliens and insects and 817 00:43:48,120 --> 00:43:51,240 Speaker 1: everything else in the universe. Because there are so many 818 00:43:51,400 --> 00:43:54,520 Speaker 1: wonderful and amazing things in our universe, some explained and 819 00:43:54,600 --> 00:43:59,360 Speaker 1: some still mysterious, it really is an extraordinary universe. And 820 00:43:59,400 --> 00:44:02,000 Speaker 1: I love the world extraordinary in the title because it 821 00:44:02,000 --> 00:44:05,839 Speaker 1: colls to mind extra terrestrial or extra dimensions, and as 822 00:44:05,880 --> 00:44:08,360 Speaker 1: my fifteen year old daughter would say, the universe is 823 00:44:08,520 --> 00:44:10,959 Speaker 1: just so extra But it also makes me think about 824 00:44:11,000 --> 00:44:16,320 Speaker 1: Carl Sagan's famous line, extraordinary claims require extraordinary evidence. Because 825 00:44:16,480 --> 00:44:19,560 Speaker 1: on this new podcast, we want to be very open minded, 826 00:44:19,920 --> 00:44:23,000 Speaker 1: ready to learn what the universe might teach us, to 827 00:44:23,120 --> 00:44:26,400 Speaker 1: ditch the dogma and accept the new ideas, from aliens 828 00:44:26,440 --> 00:44:29,960 Speaker 1: to black holes to new weird parasites. But we also 829 00:44:30,000 --> 00:44:32,040 Speaker 1: want to be clear eyed about what we can and 830 00:44:32,239 --> 00:44:35,080 Speaker 1: cannot know, what we can prove, what we have data 831 00:44:35,120 --> 00:44:38,960 Speaker 1: to support. I mean, I'd love for there to be aliens, 832 00:44:39,000 --> 00:44:41,680 Speaker 1: but I also know that hard evidence for alien visitors has. 833 00:44:41,600 --> 00:44:43,160 Speaker 2: Been pretty hard to come by. 834 00:44:43,400 --> 00:44:46,600 Speaker 1: I'd love to unravel the mysteries of quantum mechanics, but 835 00:44:46,800 --> 00:44:48,799 Speaker 1: a lot of the ideas out there are well, they're 836 00:44:48,840 --> 00:44:52,440 Speaker 1: still kind of out there.
