So, my job was to talk about everything else, a task for which I was woefully unsuited, as a particle physics theorist, but someone who was young and naive and willing to take on new tasks. I'm always amazed by physics and astronomy [thesis] defenses, because it seems like the committee never asks the kinds of questions like, what do you see as your broader contributions to the field? Physicists have devised a dozen or two . Eric Adelberger and Chris Stubbs were there, who did these fifth force experiments. Sean, for my last question, looking forward, I want to reflect on your educational trajectory, and the very uncertain path from graduate school to postdoc, to postdoc to the University of Chicago. Anyway, Ed had these group meetings where everyone was learning about how to calculate anisotropies in the microwave background. The discussion with Stuart Bartlett was no exception. In footnotes or endnotes please cite AIP interviews like this: Interview of Sean Carroll by David Zierleron January 4, 2021,Niels Bohr Library & Archives, American Institute of Physics,College Park, MD USA,www.aip.org/history-programs/niels-bohr-library/oral-histories/XXXX. "Tenure can be risk averse and hostile to interdisciplinarity. Chicago horn is denied tenure - Slippedisc What happened was there was a system whereby if you were a Harvard student you could take classes from MIT, get credit for them, no problem. What I mean, of course, is the Standard Model of particle physics plus general relativity, what Frank Wilczek called the core theory. That's why I joined the debate and speech team. We wrote a paper that did the particle physics and quantum field theory of this model, and said, "Is it really okay, or is this cheating? What if inflation had happened at different speeds and different directions? But this is a huge metaphysical assumption that underlies this debate and divides us. So, they knew everything that I had done. I took almost all the physics classes. I'm likely to discount that because of all various other prior beliefs whereas someone else might give it a lot of credence. She will start as a professor in July, while continuing to write for The Times Magazine. Young people. Part of my finally, at last, successful attempt to be more serious on the philosophical side of things, I'm writing a bunch of invited papers for philosophy-edited volumes. Given the way that you rank the accelerating universe way above LIGO or the Higgs boson, because it was a surprise, what are the other surprises out there, that if they were discovered, might rank on that level of an accelerating universe? It is January 4th, 2021. Maybe not even enough to qualify as a tradition. And I love it when they're interested in outreach or activism or whatever, but I say, "Look, if you want to do that as a professional physicist, you've got to prioritize getting a job as a professional physicist." He describes the fundamental importance of the discovery of the accelerating universe, and the circumstances of his hire at the University of Chicago. When I was very young, we went to church every Sunday. WRITER E Jean Carroll filed a defamation lawsuit against former President Donald Trump in 2019 claiming he tarnished her reputation in his response to her sexual assault allegations against him . That hints that maybe the universe is flat, because otherwise it should have deviated a long, long time ago from being flat. I think it was like $800 million. Martin White. I really do appreciate the interactiveness, the jumping back and forth. Sean Carroll (Author of The Big Picture) - Goodreads What Is a Tenured Employee? Benefits of Earning This Status Abdoulaye Doucoure has revealed how he came 'close to leaving Everton ' during Frank Lampard 's tenure at the club. Even if you're not completely dogmatic -- even if you think they're likely true but you're not sure, you filter in what information you think is relevant and important, what you discount, both in terms of information, but also in terms of perspective theories. You're not supposed to tell anybody, but of course, everybody was telling everybody. But I'm classified as a physicist. People know who you are. Okay, with all that clarified, its funny that you should say that, because literally two days ago, I finished writing a paper on exactly this issue. I have enormous respect for the people who do that. Besides consulting, Carroll worked as a voice actor in Earth to Echo. That's not all of it. Also, by the way, some people don't deserve open mindedness. Let's put it that way. By the way, I could tell you stories at Caltech how we didn't do that, and how it went disastrously wrong. Do you want to put them all in the same basket? Either I'm traveling and lugging around equipment, or I need to drive somewhere, or whatever. January 2, 2023 11:30 am. This is also the time when the Department of Energy is starting to fully embrace astrophysics, and to a lesser extent, cosmology, at the National Laboratories. Those are all very important things and I'm not going to write them myself. So, it's not quite true, but in some sense, my book is Wald for the common person. He received his Ph.D. from Harvard in 1993. Did Jim know you by reputation, or did you work with him prior to you getting to Santa Barbara? If the most obvious fact about the candidate you're bringing forward is they just got denied tenure, and the dean doesn't know who this person is, or the provost, or whatever, they're like, why don't you hire someone who was not denied tenure. That's a tough thing to do. And I applied that to myself as well, but the only difference is the external people who I'm trying to overlap with are not necessarily my theoretical physics colleagues. Sean Carroll's Mindscape - Wondery | Premium Podcasts I wrote a blog post that has become somewhat infamous, called How to Get Tenure at a Major Research University. I was surprised when people, years later, told me everyone reads that, because the attitude that I took in that blog post was -- and it reflects things I tell my students -- I was intentionally harsh on the process of getting tenure. The benefits you get from being around people who have all this implicit knowledge are truly incalculable, which I know because I wasn't around them. A nontrivial fraction of tenure-track faculty are denied tenure, well over the standard 5% threshold for Type I errors that we use in the sciences. There's a famous Levittown in Long Island, but there are other Levittowns, including one outside Philadelphia, which is where I grew up. So, Wati Taylor, who's now an MIT professor, Miguel Ortiz, Mark Trodden. He is the Homewood Professor of Natural Philosophy at Johns Hopkins University, teaching in both the . As far as that was concerned, that ship had sailed. It gets you a job in a philosophy department. Did you understand that was something you'd be able to do, and that was one of the attractions for you? Ed is a cosmologist, and remember, this is the early to mid '90s. And I'd have to say, "Yes, but maybe the audience does not know what a black hole is, so you need to explain it to us." And, a university department is really one of the most exclusive clubs, in which a single dissent is enough to put the kibosh on an appointment! Was this your first time collaborating with Michael Turner? Sean Carroll, bless his physicist's soul, decided to respond to a tweet by Colin Wright (asserting the binary nature of sex) by giving his (Carroll's) own take in on the biological nature of sex. Yes. People think they've heard too much about dark energy, and honestly, your proposal sounds a little workmanlike. That's what supervenience means. Again, in my philosophy of pluralism, there should be both kinds. I've not really studied that literature carefully, but I've read some of it. I wonder if that was a quasi-alternative career that you may have considered at some point, particularly because you were so well-acquainted with what Saul Perlmutter was doing. I think I probably took this too far, not worrying too much about what other people thought of my intellectual interests. We have this special high prestige, long-term post-doctoral position, almost a faculty member, but not quite. The astronomy department was just better than the physics department at that time. We'll see what comes next for you, and of course, we'll see what comes next in theoretical physics. Part of that is why I spend so much time on things like podcasts and book writing. He used that to offer me a job, to pay my salary. If this interview is important to you, you should consult earlier versions of the transcript or listen to the original tape. Whereas, for a faculty hire, it's completely the opposite. It was just -- could that explain away both the dark matter and the dark energy, by changing gravity when space time was approximately flat? No one expects that small curvatures of space time, anything interesting should happen at all. I do long podcasts, between an hour and two hours for every episode. No, not really. Sean Carroll: Universe a 'tiny sliver' of all there is I really leaned into that. It was certainly my closest contact with the Harvard physics department. The idea of visiting the mathematicians is just implausible. But it's worked pretty well for me. So, the late universe was clearly where they were invested. Give them plenty of room to play with it and learn it, but I think the math is teachable to undergraduates. Sidney Coleman, in the physics department, and done a lot of interesting work on topology and gauge theories. There's a moral issue there that if you're not interested in that, that's a disservice to the graduate students. Now, was this a unique position that Caltech tailored for you, given what you wanted to do in this next role? They do not teach either. Sean Carroll was denied tenure at University of Chicago, but he - Quora I looked around, and I'm like, nothing that I'm an expert in is something that the rest of the world thinks is interesting, really. But it was a great experience for me, too, teaching a humanities course for the first time. So, they said, "Here's what we'll do. The actual job requirements -- a big part of it, the part that I take most seriously, and care most about -- is advising graduate students. So, I was a hot property then, and I was nobody when I applied for my second postdoc. He was another postdoc that was at MIT with me. ", "2014 National Convention Los Angeles Freedom From Religion Foundation", "Responding to Sean Carroll: What If There Had Been a Camera at the Resurrection? I think I talked on the phone with him when he offered me the job, but before then, I don't think I had met him. So, the paper that I wrote is called The Quantum Field Theory on Which the Everyday World Supervenes. Supervenience is this idea in philosophy that one level depends on another level in a certain way and supervenes on the lower level. But to go back a little bit, when I was at MIT -- no, let's go back even further. You need to go and hang out with people, especially in the more interdisciplinary fields. So, for better or worse, this caused me to do a lot more conventional research than I might otherwise have done. My teachers let me do, like, a guest lecture. It was a huge success. But they told me, they said, "We talked to the people at Chicago, and they thought that you were just interested in writing textbooks and not doing research anymore." Do you ever feel that maybe you should just put all of that aside and really focus hard on some of the big questions that are out there, or do you feel like you have the best of both worlds, that you can do that and all of the other things and neither suffer? If it's more, then it has a positive curvature. [29], Carroll is married to Jennifer Ouellette, a science writer and the former director of the Science & Entertainment Exchange.[30]. So, that's one of the things you walk into as a person who tries to be interdisciplinary. That's what really makes me feel successful. This transcript may not be quoted, reproduced or redistributed in whole or in part by any means except with the written permission of the American Institute of Physics. A lot of people focus on the fact that he was so good at reaching out to broad audiences, in an almost unprecedented way, that they forget that he was really a profound thinker as well. As far as I was concerned, the best part was we went to the International House of Pancakes after church every Sunday. There's nothing like, back fifteen years ago, we all knew we were going to discover the Higgs boson and gravitational ways. Carroll has been involved in numerous public debates and discussions with other academics and commentators. He points out that innovation, no matter how you measure it, whether it's in publications or patents or brilliant ideas, Nobel Prizes, it scales more than linearly with population density. Actually, Joe Silk at Berkeley, when I turned down Berkeley, he said, "We're going to have an assistant professorship coming up soon. That's fine. Atheist Physicist Sean Carroll: An Infinite Number of Universes Is More No, tenure is not given or denied simply on the basis of how many papers you write. But other people have various ways of getting to the . I worked a lot with Mark Trodden. The other anecdote along those lines is with my officemate, Brian Schmidt, who would later win the Nobel Prize, there's this parameter in cosmology called omega, the total energy density of the universe compared to the critical density. For similar reasons as the accelerating universe is the first most important thing, because even though we can explain them -- they're not in violation of our theories -- both results, the universe is accelerating, we haven't seen new particles from the LHC, both results are flying in the face of our expectations in some way. I do remember, you're given some feedback after that midterm evaluation, and the director of the Enrico Fermi Institute said, "You've really got to not just write review papers, but high impact original research papers." People didn't take him seriously. And that's the only thing you do. Who knows what the different influences were, but that was the moment that crystalized it, when I finally got to say that I was an atheist. Brian was the leader of one group, and he was my old office mate, and Riess was in the office below ours. Alright, Sean. Bob Geroch was there also, but he wasn't very active in research at the time. And I have been, and it's been incredibly helpful in various ways. So, it's sort of bifurcated in that way. [5][6][7][8] He is considered a prolific public speaker and science populariser. In fact, I would argue, as I sort of argued a little bit before, that as successful as the model of specialization and disciplinary attachment has been, and it should continue to be the dominant model, it should be 80%, not 95% of what we do. Some people say that's bad, and people don't want that. But I think, that it's often hard for professors to appreciate the difference between hiring a postdoc and hiring a faculty member. But I would guess at least three out of four, or four out of five people did get tenure, if not more. Like you said, it's pencil and paper, and I could do it, and in fact, rather than having a career year in terms of getting publications done, it was a relatively slow year. Okay? I taught both undergraduate and graduate students. So, the string theorists judged her like they would be judging Cumrun Vafa, or Ed Witten. Where was string theory, and how much was it on your radar when you were thinking about graduate school and the kinds of things you might pursue for thesis research? What were the most interesting topics at that time? But then there are other times when you're stuck, and you can't even imagine looking at the equations on your sheet of paper. Why did Sean Carroll not get tenure? - Steadyprintshop.com This didn't shut up the theorists. : Saturday 22 March 2014 2:30:00 am", "How To Get Tenure at a Major Research University | Cosmic Variance | Discover Magazine", "Sean Carroll Awarded Guggenheim Fellowship", "Sean Carroll's Mindscape Podcast Sean Carroll", "Sean Carroll Bridges Spacetime between Science, Hollywood and the Public | American Association for the Advancement of Science", "Meet the professor who helped put the science into Avengers: Endgame", "Sean Carroll the physicist who taught the Avengers all about time", "Sean Carroll Talks School Science and Time Travel", "Spontaneous Inflation and the Origin of the Arrow of Time", "3 Theories That Might Blow Up the Big Bang", "Science and Religion Can't Be Reconciled: Why I won't take money from the Templeton Foundation", "Science & God: Will Biology, Astronomy, Physics Rule Out Existence Of Deity? I don't think that was a conversion experience that I needed to have. One of the best was by Bob Wald, maybe the best, honestly, on the market, and he was my colleague. So, between the two of us, and we got a couple of cats a couple years ago, the depredations that we've had to face due to the pandemic are much less onerous for us than they are for most people. It's taken as a given that every paper will have a different idea of what that means. And, yeah, it's just incredibly touching that you've made an impact on someone's life. Certainly nothing academic in his background, but then he sort of left the picture, and my mom raised me. It's almost hard to remember how hard it was, because you had these giant computer codes that took a long time to run and would take hours to get one plot. Another paper, another paper, another paper. Often, you can get as good or better sound quality remotely. Let's face it, quantum mechanics, gravitation, cosmology, these are fields that need a lot of help. Well, that's not an experimental discovery. So, that appeared in my book as a vignette. It is fairly non-controversial, within physics departments anyway, and I think other science departments, with very noticeable exceptions. In retrospect, there's two big things. But maybe it's not, and I don't care. And who knows, it all worked out okay, but this sort of background, floating, invisible knowledge is really, really important, and was never there for me. I love it. Completely blindsided. Now, the high impact research papers that you knew you had written, but unfortunately, your senior colleagues did not, at the University of Chicago, what were you working on at this point? I sat in on all these classes on group theory, and differential geometry, and topology, and things like that. I was unburdened by knowing how impressive he was. So, this was my second year at Santa Barbara, and I was only a two-year postdoc at Santa Barbara, so I thought, okay, I'll do that. If you've ever heard of the Big Rip, that's created by this phantom energy stuff. In a sense, I hope not. I did also apply, at the same time, for faculty jobs, and I got an offer from the University of Virginia. So, the ivy leagues had, at the time -- I don't really know now -- they had a big policy of only giving need based need. I got to reveal that we had discovered the anisotropies in the microwave background. We had a wonderful teacher, Ed Kelly, who had coached national championship debate teams before. Now, you want to say, well, how fast is it expanding now compared to what it used to be? The Santa Fe Institute is this unique place.
