The Economist covers math, physics, philosophy, and AI in a manner that shows how different countries perceive developments and how they impact markets. They recently published a piece on China's new neutrino detector. They cover extending life via mitochondrial transplants, creating an entirely new field of medicine. But it's also not just science, they analyze culture, they analyze finance, economics, business, international affairs across every region.
I'm particularly liking their new insider feature was just launched this month it gives you gives me a front row access to the economist internal editorial debates where senior editors argue through the news with world leaders and policy makers and twice weekly long format shows basically an extremely high quality podcast whether it's scientific innovation or shifting global politics the economist provides comprehensive coverage beyond headlines.
Recently, there's been a huge hubbub and I'm sure you're aware regarding the purported crisis in physics. I had an interview with Sean Carroll and he defended academia. His defense though wasn't just out of allegiance to academia.
To me, it seemed a counterpoise to the growing societal mistrust in science and he sees that as a detrimental trend. Today, I would like us to focus on not only the stagnation in fundamental physics, which is a specific claim, but perhaps the crisis in physics in general, maybe even science as a whole.
And I'd like to hear what you have to say. I'll bring up objections as they occur to me, perhaps other people's objections as well. And I want to hear your objections to those objections and we can even get into the issues of causes and solutions. Okay. Well, why don't you distinguish the crisis in fundamental physics versus the crisis in physics? And then we can get to science afterward. And also what is, what is meant by crisis? Cause I made a claim of stagnation to Sean Carroll, which is different than crises.
Right. So it's actually when I give talks about this, this is always the first thing that I say. Like I don't want I don't like talking about crisis. I talk about stagnation because it's clear what it means. You know, a lot of people actually think like if we had a real crisis, that would be a good thing because the crisis is an opportunity for a breakthrough or something. So we would know what to hit on. But that's not what it is. So to me, I think
Calling it a stagnation is much more accurate because that's what I see. We're just not going anywhere. We're just, you know, like on a treadmill pretending we're running, but not making progress.
I actually can't remember I've ever talked about the crisis in physics overall because I don't really know a lot about exactly what's going on in physics overall. It's just such a huge field with so many sub-disciplines.
So I tend to focus on what I call the foundations of physics, where we think about the most fundamental questions, because that's what I know about. And so the issue there is that we haven't really made any progress on answering the big open questions ever since they occurred, like a century ago.
And then we made progress until the Standard Mall was completed sometime in the 1970s, depending on how you count.
And then you could say, you know, for the next five, 10, 15 years or something, people were just trying out different things and they expected it to go somewhere. And at some point, you know, sometime in the mid 1980s, maybe 1990s, it just went wrong because what happened was that they started doing the same thing over and over again and it just didn't work and they never revised those methods.
So we still don't know what dark matter is made of, if it's made of anything. We still haven't figured out how to quantize gravity. We still don't really understand how quantum mechanics works. So we haven't really found either a better theory or some phenomenon that we could actually hit on. How are people supposed to resolve some of these foundational problems such as quantum gravity, as you mentioned, or dark matter without experiment to guide
or to test between different
you know strictly speaking one shouldn't lump all these problems together because each problem is its own problem and dark matter is quite different from the other problems that I mentioned because in this case we actually do have some experimental data like so we know something isn't adding up like quite literally actually if we just take the matter that we know of that we have in a stand-up model and we put it out there it just doesn't probably work and so introducing some sort of dark stuff
is a fix that you can do but for one thing it doesn't always work the way that it should be so it brings up some other problems and also it opens the question like what is it made of is it made of anything and then there's this competing theory modified Newtonian dynamics or modified gravity in more general and we still haven't really you know figured out how to rule one out or confirm the other or yeah
So and then these other questions which we have like quantum gravity is often portrayed as a problem of inconsistency and we can talk about what exactly this means. Quantum mechanics I've personally argued it's also a problem of inconsistency but I think if you ask other people in the field they would object that this is the case.
and then there are other problems that people like to talk about which i actually think are not problems which are some misgivings about the standard model for example like you know the strong cp problem or it's supposedly unnatural likewise the x-mass or small the the hierarchy problem as it's sometimes called
And there are a list of other issues that people have, like the baryon asymmetry and stuff like that, where I would say these are not good problems because it's not clear that they actually require a solution.
So you can say, I don't like it that the standard model just has these three generations and we have no deeper explanation for it. But maybe that's just how nature is. Maybe nature just has three generations and there's no deeper explanation. So I think it's not a good problem to work on because we have nothing really to start with. There's no problem that's actually in need of solving, if you see what I mean. It's not the case with
quantum gravity where you can say okay actually if we just take general relativity and we combine it with the quantum field theory it doesn't work we don't know what to do so we there's a real need to actually develop new mathematics and i think that's what makes this a promising avenue.
Just for people who are unaware of some of the problems or so-called problems, one is about CP violation and then there's something called theta which looks to be zero or close to zero and then physicists don't like small values because they like to have some function that has a minimum of a small value so they can say okay that's the reason for the small value and you would say those are pseudo problems because maybe the reason is just how nature is. So let's talk about actual problems which I believe you
Put into two categories, one of inconsistency with data. So perhaps the muon experiment would be that or the data from it. And then the internal contradictions. So let's stick with internal contradictions. Quantum gravity is one and the projection axiom of quantum mechanics is another. Is there another or is it just those two for the internal contradictions?
Well there are more technical issues related to quantum field theory but it gets very it gets very mouthy very quickly so maybe let's leave those aside but yeah there are some other mathematical issues that people have like for example I mean you can ask like is quantum field theory actually a well-defined framework to begin with
Interesting, that's super interesting. I didn't know that. I thought you're going in the other direction of any progress towards well-defining QFT.
This is what I said I don't I don't want to talk about So yeah, because I don't really know really this isn't something I have like axiomatic quantum field theory It's not something that I've my myself worked on. So I know it exists I knew there are problems that people work on But I don't really know a lot about it. So it's I see, you know It's not a good topic to talk about because I just be talking random nonsense. I
I see, I see. So something I was going to say was, okay, would you consider soft theorems and asymptotic symmetries as progress in physics or progress in double copy relations like gauge gravity dualities or gauge gravity relations?
Well, this is all very interesting in the sense that it helps us to better understand the theories that we already have. But they don't really help us. You know, it's no it's no new physics in the in the sense that it's not a fundamentally new phenomenon that has been predicted. It doesn't really at least I don't see how it helps us answering these questions like the big questions that we just talked about. So
So, of course, you know, people who work in the field, they see a lot of progress because they write a lot of papers. They try very hard to understand the mathematics. And I'm not saying that this is all useless, you know, especially I recently talked about this in a video, the Ampli2 Hedron. Yes.
Stuff so that's a very interesting development and the entire area CFT stuff is also pretty cool You know that learning a lot lots about the mathematics of gauge Theories how quantum field theory actually works like there are many more structures than we thought there are but
You know, when it comes to those big fundamental questions that we started out talking about, at least right now, I don't really see what we learn from it about this. So there's a there's a long story about Neemakani Hamed and you know, the demise of space time or it's doomed, right? This is like space time is doomed like this is the catchphrase.
And that might be like, so maybe this is actually the way to do it. So maybe we have to describe quantum physics in terms of these amplitude hydra and that will give us a clue for how to deal with quantum gravity. But at least at the moment, I don't see it happening.
Yes, and you also see that as an argument of serendipity, that hopefully if we explore this, we're going to stumble upon a solution, but there are multiple different avenues we could have gone down. And if we constantly justify our explorations, we'll stumble upon something that'll be useful. So, yeah, well, so the issue is, so serendipitous discoveries have happened and they'll probably continue to happen. But the question is, like, how likely is it?
So i don't have a big problem with people like actually i don't have a problem with most people period so you know research avenues like the up to he drawn all area safety and another very math heavy stuff.
My teachers something and yes you know something surprising might come out of it but i don't think it's a you know just historically it's not been a super productive strategy and historically people have also had
The advantage of having some data to go by so you already raised this question like so this is like the big issue like we don't have any data to guide us to a theory of quantum gravity.
That's what this channel is about.
So what do we do Kurt? So do we just make videos about everything and then at the end of the day, we have a vote about which is the nicest one? I think that's not a good way to do it. Well, for me, the Amplitohedron didn't impress me. It was interesting, but it was specifically for a certain type of quantum field theory and equals for super Yang-Mills planar as well.
But then it's been generalized recently to shapeology, I believe. I believe it's shapeology. So now it can calculate without supersymmetry for phi three, phi cubed, I believe. But anyway, the point is that you would classify that as cool, but not progress. Well, you know, in some sense, it's progress, but it's not progress on the questions that we talked about. Right. So at least I don't see how it's the case.
So we were, you know, we can have an endless discussion about what exactly do we mean by progress, right? Is it progress to write a paper? Yeah, well, so I think, you know, personally, what I'm talking about is making progress on
finding some sort of new physics like and this to my mind is better understanding the theories that we already have and yes you can call this progress in some sense but it's you know it's not personally what i'm interested in and honestly i think it's not what most people are interested in when they when they talk about the foundations of physics you know and then you come back and say yeah but actually you know we have calculated some diagram to three more digits or something they're like oh yeah i'm cool nice
So there's a great diagram in one of your videos and I'll overlay it on screen. I'm going to make it simpler than it is where you show here's the standard model on the X axis. Let's just imagine standard models predictions are a straight line instead of a curve and then deviations from that are what people predict. But we've only tested up until from zero up until here and so far the standard model is correct.
We do have a variety of different theories that make predictions but
They also lie outside the experimental range. So outside of dark matter, even though we don't have, we don't know if dark matter is a particle, like no one's detected a dark matter particle. So we just have the distribution of dark matter and my issue is
It's so difficult to have progress in physics without experiment guiding us. Then the other question is, okay, well look, if progress is difficult, why are we writing all these papers? And so I assume that that's part of your critique. And I wonder if embedded in that critique is, and taxpayers are paying for this. And then I wonder how much of your issue with the paper production, academia as a whole would go away if it wasn't taxpayer funded.
Why we still wouldn't make progress. So, you know, just because you stop paying people doesn't help us understand quantum gravity works. But yeah, so I think it's kind of a double combination. You know, I'd say, well, you know, if they're not actually making progress, then what are we paying them for?
So it's like a double insult. It's not only you think they should actually make a little more effort. Let me put it that way. But actually we also have to pay for it. So but yeah, so just just stopping to pay them isn't going to help much. At least I don't think so. We have to think about some other way to do it. So I really think it's a it's a systemic problem.
And I also think that it's very field dependent exactly how these problems manifest, but at least in the foundations of physics, we're seeing this overproduction of predictive models that are being ruled out over and over again.
What I've tried to convey is that this is a methodological problem that physicists even think that this should work. And I really think it's some sort of misunderstanding of the philosophy of science. They think that just because you can write it down in mathematics and it's falsifiable because in principle you can make a measurement and rule it out.
It's good science. And I've tried to convey to them, that's not right. You know, for it to actually be a scientifically useful hypothesis, it's got to solve some problem. The only thing you do is that you add something on top of the stuff we already have, but we don't actually need this for anything. And, you know, just on a purely mathematical level,
It's fairly obvious why this doesn't work because there are like infinitely many of these possible predictions that you can make. So the probability for any one of them to be right is zero. So I'm not surprised that it doesn't work. And as you know, in my book, I've argued that if you look at the history of physics, the theoretical breakthroughs came from solving problems of inconsistency.
And so this is just an observation which I believe is to be correct. I don't actually know why this is the case but it seems to work and so this is why I've been saying we should focus on solving inconsistencies like for example in quantum gravity, quantum mechanics and forget about these pseudo problems like the hierarchy problem, strong CP problem and so on.

Well, imagine your critique would also apply to the various theories of quantum gravity that exists like loop or string, because string people would say, what we're doing is, well, we've solved one of the major difficulties in combining general relativity with QFT. Namely, you can't go all the way down to zero because you have a minimum string length and you get gravitons popping out of the theory without putting gravitons in the theory, isn't that progress? And I imagine you would say,
Either you would say maybe at first or you'd say no wholesale. So what do you say to that? What do you say to the numerous approaches to quantum gravity? Yeah, well, consistency is all well and fine, but it's not the entire story. It can't be because there are always multiple ways to resolve mathematical inconsistencies. This is why we have these different approaches to quantum gravity, string theory. And, you know, we can talk about which one
You know, they all have problems, let me put it this way. And there's a lot of argument about which one is better and which problems are more severe. But so we have strictly quantum gravity asymptotically safe gravity. And then there are some lesser known approaches like causal dynamical triangulation. So honestly, I don't know what happened to this. I haven't heard anything about this for some while. Maybe causal sets, which now seem to have somewhat of a revival in this hypergraph
which I find very interesting. But so in the end, you know, if you have a theory, you still need to go and test it. And I think the possibility, actually the need to test quantum gravity has been neglected for a long time because physicists just thought, well, it won't ever be testable anyway, which raises the interesting question where if that's what they thought, why were they working on it to begin with? Because then it's not really science.
So in any case, so the interesting thing is that like in the past 10 years, this discussion has entirely shifted to, yeah, we might actually be able to test it. And I think the reason that this shift happened is that for a long time when people talked about testing quantum gravity, they had in mind what's called the strong gravity range.
Where you would actually see, is it strings or is it loops? So you'd be able to tell apart the details of whatever's going on at high energies. But actually, you should also see quantum gravitational effects in the weak field limit, which we can test in the laboratory.
In principle, you know, we're not quite quite there yet, but maybe we'll get there like in a decade or two. And I can talk more about this. But, you know, I think that's a very interesting shift because people are now actually thinking about how to make predictions for experiments that might actually happen at some point. Yeah, I actually I spoke to Yvette Fuentes about her proposal for how to test quantum gravity in the lab.
And then same with Chiara Marletto. There are different proposals that are being articulated. Now, you said solving internal inconsistencies is one thing, but again, there are a variety of them. So that seems to me it's not a sufficient condition. It's a necessary condition to solve internal inconsistencies. What else would be a condition then? If you were the grant body, Sabine's the grant body, and people are coming to you with proposals,
For you to give some money to someone in the theoretical physics and what are you looking for? You know, honestly, I would just tell them don't ask me like I think it's not a good procedure. We should go above this in some in some smart way. I mean, so the most obvious thing that I always tell people is learn from your mistakes.
And this is exactly why I am so annoyed about what's going on in the foundations of physics, because that's not what they're doing. Like they're just making the same mistakes over and over again. And so, and this is also the reason why we see so little novelty, because they're just, you know, continuing to repeat the same stuff in, you know, slightly different variations, but there's no big
Change and and then also this entire societal Problem where people who try something different have trouble getting funded So Yeah, so I guess This would be one of the major points I think there needs to be if you want people to start something really new They need more time than you have on most of the current
Grants that you get which are typically that there are two or three years Which in practice it means that you have to think about applying for the next grant the moment you start working on the current one And it just makes people very very risk-averse
because you know you have this pressure in your back that you need to bring in money again soon so you need to produce results like reliably several papers a year or something like that otherwise it doesn't look good so you can't just say i'm going to think about this big question for the next five years and see what comes out of it it's not possible
And of course, you know, you don't want to hire like 10,000 people who just sit around and think big thoughts. That doesn't make sense either. But I think you need a few people at least being able to do this. And it looks to me like we just have too few people who can do it. And it's becoming fewer and fewer instead.
And the other issue which I've talked about in my first book quite extensively is the issue of self-reinforcing bubbles that you get in research, of which I think string theory is a very good example, string theory and also supersymmetry.
you know all these beyond the standard model predictions that I made for the LHC which didn't work out because what happens is that once you've made your PhD in a particular
region you get you get a postdoc in it you apply for grants on it at some point it becomes basically impossible to change topic because no one will give you money no one will hire you because it would take like a year or maybe two years to learn something new.
So I think a very simple thing we could do to prevent this self reinforcement because people can't get out of the field so they're constantly forced to tell themselves that this is what they want to do and you know to attract more funding to the same thing is to just give people a chance to start something new without pressure to having to produce papers immediately like some kind of
You know, refocusing grant, or maybe that's not a good word, you know, redirection grant. Yeah, interesting. Okay. So sounds like two solutions is okay. Well, one problem that people think is that there's the reliance on grants, but you're saying it's not just a reliance on grants. It's a reliance on these short term grants, short term being two to five years, because in order to make large progress, you need much longer time scales. So an over reliance on short term grants, and that
The grants don't pay you to switch topics and switching topics may be necessary. So we have sour grapes, which is that if you're trying to achieve something and then you fail, you look at that and then you start to scorn that. But we have the opposite, which is if you have something, you start to adore it. In string theory, you start to adore it and start to think that it's what's required to bring you forward or the field forward. Correct my incorrectness here.
I'm pretty sure that's part well so I don't know like so I'm not I haven't psychoanalyzed the entire strengthly risk community like so I mean I've interacted with some of them and I think that most of them
They actually believe in what they work on so I think it's genuine and I think it's mostly because the people who are not actually convinced that this is a good thing to do they just leave because it's not that the working conditions are so great.
You have to have enough motivation to take some pain, basically, to stay in academia. I think most of these people are generally motivated, but much of it comes from the social reinforcement. They live in a community where people constantly tell each other that this is the right thing to do.
And especially in the string theory community, this was at least 20 years ago when I had more to do with them. It was quite extreme. Like they rarely ever talk to someone who was not a string theorist. And so it's actually, again, this is just my impression. It's actually become much better since there's more of the ADS-CFT stuff because that ties into other research areas like condensed matter physics, heavier iron physics, and that sort of stuff. So it's less isolated now.
Yeah, that was the point that I brought up to Sean Carroll, because Sean was saying, well, I was suggesting to Sean that he was misrepresenting the views that are saying that there's a crisis in physics, because the people who are saying that are actually making an extremely specific claim about theoretical physics and fundamental laws, not just physics as a whole. And he started spouting off engineering feats, like look at topological phases of matter or condensed matter physics, and so on, and so on. And I was saying, okay, well, but that's not what your opponents mean.
And then I was saying that if there is a crisis and not just a stagnation, it's a combination of a stagnation and a silence with the silence being that in the string community say they don't listen to theories that are outside of it. In fact, they don't know. And then they'll say that the only game in town. And then when I speak to string theorists and I bring up alternative theories, they'll say, well, I don't they couldn't recapitulate them in a manner that the theorist would agree with.
So when I, like 20 years ago, when I actually worked on quantum gravity, mostly on the phenomenology of quantum gravity, so I've always been interested in how can you test this stuff and you can try to squeeze some predictions out of string theory phenomenology or you can take loop quantum gravity or you can take other approaches.
So this is why i've interacted with people who have worked on all kinds of different stuff and it's certainly true that usually they didn't know what the other people were even talking about like they had a lot of prejudices and sometimes you know it was a little bit silly
so i don't really know what's happened in the past 15 years because i just stopped working on this but as i said it's like my impression is just vaguely it's like the entire loop quantum gravity stuff has totally spun off into its own direction like so no one has any idea what these people are doing they just you know they just do their stuff
And then you have the string theorists which the entire community split up into two camps basically so there's one this is now the much smaller camp. Are those which think that string theory is like a theory of everything and then we give us the correct theory of quantum gravity and all that kind of stuff.
And then you have those people who think of string theory as a useful tool to better understand quantum field theory. And this is where most of the ADS CFT stuff now lives. You know, it's a tool to better understand strange metals like this is a typical, you know, selling point that people like to raise. And, you know,
is possible. Generally, I think that the possibilities have been hugely overhyped, but I would probably say this about pretty much everything. So it's not specific to string theory. But yeah, I mean, so this is not specific, I think, to this particular research direction. You see this in a lot of other areas, too, that people are kind of forced to over specialize and they fall apart into different
camps and they have to have some reason for why their stuff is better than that of the other people. And often they do this by just ignoring what the other people do. You also see this in astrophysics in this debate between dark matter and modified gravity. It's actually quite shocking how many of the people who are totally opposed to modified gravity have no idea how it actually works.
Thanks. I've seen this with my own eyes. They're just like, no, we know that dark matter is the thing. And then they point to something totally silly, like the bullet cluster, you know, which, you know, this the bullet cluster is like this one observation, which is neither here nor there. Like, so it's generally hard to explain with everything seems to be a statistical outlier, whatever. But they have like this catchy image, you know, this with the with the blue and
red you should show this image why i fumble around here so doesn't make any sense and i say this proves it uh well if you look at the details it's just not true uh and so i always find this a little bit distressing that uh actual astrophysicist who should know this stuff like who should actually look at the details would look at this like is it actually true
Does it actually rule out modified gravity? Because it doesn't. You could as easily spin a story that says it rules out dark matter. So and there are other stories like, you know, with the cosmic microwave background. And this is all stuff that Stacey McCall has been going on like forever. You know, how actually the peak of the CMB actually ruled out dark matter.
You know, if you look at the predictions, I looked at this at some point, it's actually true. You know, they made a prediction which actually disagreed with what was observed, but they did not conclude that dark matter has been ruled out. Instead, they, you know, they fumbled around with the theory. And so the distressing thing about this is that if you talk to astrophysicists, they will not know this stuff. Like, so it's not in the code of their group.
Basically so it just becomes forgotten and this is what i find terribly distressing you know it's one thing to draw different conclusions from the data that's fine but just not even know what's going on elsewhere that's not good you know that that's a serious community problem.
So then do you see another grant being, hey, know your competitors or do you think that's just that's part of your job as a physicist? Yeah. And so I think that physicists, not just physicists, like this is an overall science thing, they need to be more conscious about these
social dynamics that force them into some corner where some things can just become totally forgotten or they're so convinced that something is actually correct they never themselves go and check it.
And so this is, I find this hugely worrisome and this is also the reason, by the way, while we had all these wrong predictions for what would happen at the LHC, you know, all the stuff about supersymmetry and dark matter particles were supposed to show up in extra dimensions and gravitons and black holes and whatnot. Well, they were all, you already alluded to this with the theta parameter
They were all predictions based on this idea of naturalness, which is not a scientific criterion. It's ultimately, if you look at it, it's an argument from beauty. And I've tried to talk to people in this community, like before the LHC even turned on. So I was trying to figure out like, why are you using this? Why do you believe in this?
and they insisted it's a mathematical criterion and and you can you can still see this like on the archive today people still use these arguments and i think this is just a fundamental
misunderstanding of what's going on. So they've grown up learning that this is how you construct a theory that this is a good criterion. And they never they never questioned this, where I would say, well, you should, you know, you should not just trust these other people what they say. And so yes, you so in the beginning, you asked this question about trust in science. And this is like, one of the key reasons why I have
This is a great point to talk about the general mistrust in science, but also your issues with science in general. So let's get to the so-called crisis in science. I believe, let me double check if you have a YouTube title. Well, you could tell me if you have a YouTube video called the crisis in science.
And it wasn't referencing someone else, like you're actually stating there's a crisis. Yeah, I've certainly stated this, but I can't remember what the title is. Sorry, because I, you know, I change the titles frequently. So I have no idea what the current titles you have to look it up. Okay, so let's give some behind the scenes to people who aren't YouTubers and don't know about testing thumbnails and testing titles. And then they just see something like the crisis in physics. Let's just imagine you came up with a thumbnail like that, or your team did. And then they say,
Sabine, what you're doing is clickbait and you're the one contributing to the distrust in science with such inflammatory remarks. So what do you say to that? Give people some behind the scenes. People used to make fun of how bad my thumbnails are.
So if they now say your thumbnails are clickbait i'm like yeah finally figured out how to do them but someone was seriously i think most of the people who complain about titles and clickbait and you know youtubers are just doing this for the clicks and whatever they don't know the first thing about how youtube works so if it was that easy to do a clickbait video and get rich with it everyone would be doing it.
So yeah, I mean, as you already alluded to, so typically we write down a whole set of titles. We produce a whole set of thumbnails, which luckily now you can automatically test at least three of them. If you have more, you have to iterate it a few times. And the thumbnail and title you see at the end is the one that works best.

And so that's how it works. And yeah, I mean, so of course, everyone I think on YouTube tries to find a way to communicate the message of the video to their audience in the best way.
And typically I just try to find something, you know, sometimes that's a really dumb way to summarize what's in the video. So in this video I explain XYZ because I found that the titles that really don't work are those which misrepresent the content of the video. Often that's, you know, not deliberate.
but you know i look at it later and i'm like i think people it's about something else than what it actually is about and it's surprisingly difficult i mean there's a reason why big newspapers have headline writers because that's not simple
So, you know, I know this now sounds like I'm apologizing for something. I'm just trying to say, you know, it's it's not as easy as people make it sound. I usually just try to be really to the point. And I guess that's kind of my trademark. You know, I just say things as they are. And some people find it offensive. I suppose that's just how I am. Have you always been that way? Yeah, pretty much. You know, a lot of people blame it on me being German.
Maybe that's partner. I think you blame it on yourself being German. Yeah, I mean to some part I mean I've heard this I've heard this a lot like this is a stereotype like Germans are this is what I've been told Okay, so Germans are very direct and they often come across as as impolite or unfriendly And you know if that's what people think then I guess that's too. I'm not deliberately trying to be impolite or unfriendly and
And I think most Germans wouldn't see me that way. But yeah, I mean, so I guess I've, you know, I've always been more the kind of person who said, I think that's bullshit. And then I just say that it's bullshit. Yeah, and I guess some people find this appealing somehow. Yeah, I think that's an inveterate personality trait.
I think that's trait agreeableness in the big five model of personality, which has a heavy genetic component. So maybe there is some truth about Germans though. I need to see a population study. Definitely got it from my mother. Okay. Now what about humor? Yeah, what about it?
Your videos have plenty of jokes. Are those your writing? Is it your team's writing? Is that something that runs in the family? Is something that comes naturally? No, I actually do them myself. I've tried to outsource them to other people, but it doesn't work very well. I tend to find other people jokes funny. There's also the issue that I try really hard to make my jokes kind of
intelligent, if that makes sense. So they're actually often about the science. Some of them are insider jokes that I think most people won't really understand. So it's really hard to leave this to someone else.
so I've been doing it myself you know some days I feel more funny than other days you know sometimes it's really difficult to come up with some joke which is also one of the reasons why I used to make these phone jokes you know that the phone would ring and it would be the president and I would be like oh yes we will adjust the phone structure constantly immediately or something
And the thing is that it took me a really, really long time to come up with these jokes. I now have much more respect for stand-up comedians and people who are professionally funny because it's just so difficult. At some point also you don't want to repeat yourself too much. So this is basically why every once in a while I do it, but not as regularly as I used to.
I used to do stand up when I was 18 and what you do is you get an open mic, five minutes of an open mic and I told myself every time I go to an open mic, I'm going to come up with a new five minutes and it was so much work.
And I bombed, so I did extremely well the first few times and then I bombed in my fifth or my fourth or sixth time. And then I remember that crushed me because I did so well the first few times and I just had this pride and this overconfidence. And then I stopped doing it for a year afterward because I was so traumatized from that. So what did you start doing it again? Well afterward and then I, I continued doing it for a while afterward and then it petered off because I became a filmmaker and I used my math skills for, for that and then became
a podcast or using the math and the physics for my undergrad. Okay, that's pretty cool. I would actually like Yeah, I'd be very interested in hearing some of the stuff. But yeah, so yeah, no, think about it. I'm serious. It's embarrassing.
And it can't be more embarrassing than my stupid jokes. But yeah, so if you talk about science, you know, if I do a video about, I don't know, the amplitohedron or something, there's this additional problem that people need to understand. It's a joke. Like, so if you go to a comedy show, you know, you're supposed to laugh.
Yes, yes. So I kind of have to, I always have to make sure that people actually know it's a joke. And now you're supposed to know. Well, part of that could also be the editing. So when you're about to launch into a joke, the camera zooms in or your team cuts in. We do this. Right, right. And, you know, I have kind of this joke voice, you know, with this kind of signals to people now that's a joke. You can laugh now. But it doesn't always work. You know, some jokes just
I think just for flat people don't really see what's funny about it or something so yeah it's so it's much more difficult than most people think i guess. Do your kids find you funny. So i don't know do you have children no.
So the thing about children is that up to a certain age, they don't understand jokes. And I found this to be it is kind of bizarre because I constantly make little jokes, you know, little ironic, you know, statements about, you know, something like, Oh, really, I would never have thought about this.
You know, if I drop something, right? And you have this five-year-old who says, mommy, you just dropped an egg. And I'm like, oh, really? You don't say, you know, this sort of thing. Children don't understand that it's sarcasm. And so they'll take it seriously. And then they will point out, yes, there's an egg. And you're like, yes, yes, yes.
and so at a certain point they start understanding this like around the age of nine or ten or something and mine are now in the age where they start making their own jokes so I find this very interesting so it's like you know they're kind of trivial jokes at this point sarcasm is particularly simple I think I actually try to not use it all that much because it's kind of too simple and then you know people
You mean to say in your videos. Yeah, it comes across. So I've actually of course, I've tried chat GPT to get to to write jokes, but most of what chat GPT generates are sarcastic remarks and they always sound more or less the same. So it becomes really boring.
but yeah i think i guess that's like the the simplest thing to do and you know i've i've like three four books uh titled how to be funny or the most common types of humor that's hilarious that's hilarious isn't it that's so funny yes yes you're studying it's like it's yeah go on i'm a scientist right yeah this is sabine i'm sorry sabina i should be saying sabina correct yeah but don't worry about it all right sabina
One of the reasons I got into comedy, I never said a single funny thing until I was 18. And the reason was, I love Seinfeld, I loved watching and love any comedy, but I never thought I could just produce comedy. And then I thought, okay, it turns out Seinfeld himself, Jerry Seinfeld didn't say anything funny, at least not to his family until he was 22. He just decided to be a comedian once he graduated. And I remember thinking,
Why can't I study how comedy works in the same way that I study a math problem? So I was taking real analysis when I was 17 and I remember some of those problems were extremely difficult and thinking, okay, why can't I just treat jokes like that? So I started writing out jokes and I started finding the formulas. And like I mentioned, when I went on stage, I did extremely well. The first few times the guy thought that I've been doing it for months. So this analytic quality of analyzing jokes does work. Yeah.
Yeah i've noticed the same i think it works up to a point because i look at the really good comedians it's a lot to do with the way of presenting things it's a lot about the acting you know they're just funny in themselves.
And I'm just, I'm a bad actor. It's like, I just can't do it. You know, I think it's like, you know, expressively, I'm not funny. So this is why the sort of jokes that I make, they're kind of not funny, funny, in a sense, you know, they're funny because they're not funny. Yeah. Yeah. So I tried to do what I can. So how do we end up talking about, about jokes? You were, you were what?
I was so rationalistic when I was 18 that I remember saying, if I'm going to come up with a joke, it has to be such that a robot could read this joke in the same intonation and it would get a laugh that it's not going to get a laugh because I'm doing something physical with my body or I have the correct confidence. And I didn't like Kramer from Seinfeld because of that. I remember thinking that slapstick and I wanted to be like Seinfeld. I looked up to Seinfeld and he said he analyzes jokes with a scalpel. He picks them apart and
down to the syllable and i like that i like playing with the words but anyhow when you and i met we at the institute for arts and ideas you talked about how you try to get people to write your scripts before you try to outsource some of it and with with people who are researchers not just script writers but it didn't work can you talk about that
Yeah, so it was not a 100% failure. I've worked together with some very good people who saved me a lot of time by doing the research, going through the literature, finding out what are the key references, reading them, what are the key points in the references.
But I've found it very hard to find, basically impossible to find someone who's both good at doing the research and actually writing a script for YouTube. And so in the end, I always ended up doing most of myself. I also had a few script writers who unfortunately brought in some mistakes.
I cycle through a lot of people very quickly.
So one thing for example which has driven me nuts is that i've always told people like so i'm a little bit over organized so we start working with me you get a long sheet which says what you're supposed to do not supposed to do because i don't like to repeat myself.
And as this like one of the key things is always don't trust secondhand references like never ever, you know, a website that says, you know, there's been a report and the report says X, Y, Z, you have to look at the report and you wouldn't believe how often you look at the original source and it actually didn't say this thing. Right.
And I still, you know, doesn't some people, you know, it doesn't matter how often you tell them, don't do this, they'll still do it. And they think they'll get away with it. And unfortunately, in the end, I'm the one who's responsible for it. Like so. And I always think that I should check everything. But of course, I don't. And I don't always notice. And this is why shit happens. And in the end, I'm the one who gets blamed. Right.
So now I mostly, I pretty much do everything myself at the moment, which is also not a good arrangement. This is why I mostly talk about stuff that I know about myself, at least a little bit. So here's something else. We tell our kids that we're not supposed to judge a book by its cover. We even claim to be living by that philosophy ourselves. You're just supposed to review the content itself, not the packaging of the content.
It's on the inside that counts. However, people will at the same time claim that they dislike the YouTube titles. So why? If the content is there, then why do you care? Is it that we're not supposed to judge a book by its cover, but please do judge it by its thumbnail? Yeah. Or are we not supposed to withhold judgment until we understand the substance or content? Like, which is it? And another one that I see is you're supposed to judge people by their own merits. But now
It seems like people are judging others based on who does their audience comprise. So in other words, it's like you're not supposed to judge a book by its cover, but you can by its sales demographics. Yeah. Well, so first of all, I don't really see this a lot in my comments and also like generally like on YouTube at least, you know, the weird things going on on ex Twitter.
Uh, as you've probably noticed, like it's a very strange place and it's becoming stranger every day. Uh, but at least for what I see in my YouTube comments, to the extent that I can read them, like, I mean, I get thousands of comments a day, so I can't really read them all. Um, I try to read as many as I can. Um, that they're mostly from normal people, I would say, you know, that they're interested in physics.
uh...
You know, the interested lay person is how I would describe most of the audience of my channel. And many of them are also students of one field or another, typically physics and associated disciplines. And of course, many of them, and I know that you get this too, are independent researchers. They work on their own stuff, and they have their own ideas about everything. And it's fine with me.
So I don't really see a big problem with this and then you get what you call the science deniers who are looking for a reason to dismiss some scientific finding that they don't like.
Very often that's climate science because it doesn't fit in their political views or something like that and they'll jump on everything which proves their point that you can't trust scientists. The thing is that I understand where these people are coming from.
As I said, what I've seen going on in my own field basically destroyed my trust in scientists and I haven't gotten it back because I haven't done anything to fix the problem. I've no reason to think that the same problem does not also exist in other disciplines, which is why I've looked very closely at what they do in climate science and I've actually been to some conferences and talked to climate scientists. I've interacted with a bunch of them.
which is why i can now confidently say no climate change is not a hoax it's a real thing and climate science the community has its problems but the problem is not that i'm making up climate change and and so my approach to this science denier problem is to
take them seriously because there was an origin for their mistrust and to try and address this like you know on a substantial basis to look at the science and say no this is why the evidence is sound and so people still have this mistrust of the institution of science and I think the only way that we can address this problem is to actually make it better
So in other words, you're counter to the people who are saying like look Sabine with your scintillating rhetoric. People love the word rhetoric. You're scintillating thumbnails or what have you that you're contributing to the distrust or mistrust of science. You're like, no. Firstly, there are some people who will always abstract away and decontextualize something and use that as ammunition for whatever their causes. So that will always be the case. So firstly, there's that. But secondly, you're bringing up issues.
that aren't talked about and now scientists are talking about them people in academia are talking about them many people in academia agree with you by the way and so you're contributing to the public trust of science or at least you're trying to bring that trust back by strengthening science is that a fair recap
Yeah, I think it's a mistake to try and sweep these problems under the rug because at least I think they're totally obvious. So here's an interesting thing that a lot of people in academia like to forget. I think it's something like 90% of people who do a PhD or who do something in academia leave. So there are a lot of people out there who have first-hand experience with academia who no longer work in academia.
And these people know perfectly well what's going on. And I actually know from the feedback that I get that a lot of the people who are very concerned about what's going on in academia, they know what they're talking about. They've seen it with their own eyes. So it's not as easy as saying that all climate deniers, you know, they're all somewhat weird in the head or something.
So I think this is a serious problem. We need to do something about it. And the first thing you need to do is to acknowledge that you have a problem, basically.

So I was surprised when you said earlier that there aren't enough people that are thinking about the foundational issues, because to me, there's an overproduction of these people. And in my estimation, from what I see from being on the inside, formerly on the inside of academia, and also from speaking to people who are on the inside and just seeing this whole trend, it seems like we're producing many, many physicists or people with physics skill sets and people with mathematics skill sets, and then they don't have a place to go. So I'll read a recent tweet.
Someone said, me after finishing my PhD, surely I'll be able to find some jobs in my field. No. Next. Okay. How about getting access to the online journals so I can continue my research? No. Okay. At least I can still upload my work onto free online pre-print repositories, right? Also no. And then you even commented this really shouldn't happen. I feel we need to create a scientific underground. So do you also see that there's an overproduction of, of scientists or you don't see that? And I want to know more about this scientific underground as well.
So the overproduction of PhDs, like this is a long standing problem that has been discussed forward and backward. And the like, I think most people who I've talked to about this agree that this is driven by the need for cheap researchers. So a lot of this bringing in grants depends on how quickly you can churn out papers.
And the more students and the more young postdocs you have that you can put on cheap positions, the better. And so you see this in a lot of institutions that I've seen this with my own eyes. Actually, you know, I was one of them is that you hire students, young postdocs, you put them on these super cheap jobs, they produce their three papers, you kick them out. But for most of them, there are no positions to land on. You know, they're just not sufficiently many jobs.
And the reason this doesn't change is that the people higher up in the hierarchy like the professors especially the younger ones they need these people to produce all these papers.
So, and I think this is why this isn't changing. I don't really know what to do about it. I'm just telling you, I think that that's what's going on. I remember this tweet and the reason I thought it was interesting is that this is a problem I've seen with a lot of people who I know who've left academia, mostly voluntarily, you know, and they went on to take some other job, you know, something that would feed the family more reliably, basically.
uh but they don't lose their interest from one day to the next you know in many cases they have unfinished research or maybe maybe they have some other research things that i want to work on and you know they do it on the weekend you know out of passion but then they have the problem
that since they're no longer affiliated with some institution, some journals won't even accept their submissions, which I think is just totally crazy. Like, why do you need a university affiliation or something to submit a paper to a journal that's supposed to be peer reviewed? That doesn't make any sense. And you can also ask like if they want to go to a conference, you know, they can't apply for any funding or something because they don't have this affiliation.
And then there is also the community problem right you no longer really tied into the community and you know you fall a little bit out of touch. And as i said earlier like.
Just looking at the numbers i don't have really i have the exact numbers on top of my head but i'm pretty sure like the majority of people have something to do with academia at some point leave eventually so this is this is why i have this tweet about.
The scientific underground, which is loosely speaking, I've become to call it, you know, it's all those people who want to do this research work but who are not affiliated with a university or some other research institute.
But so what do they do? You know, how do they organize themselves? Why can these people not apply for travel grants? Why can they not submit papers? That doesn't make any sense. And so this seems to me, if I had more time, maybe I would do something about it. You know, it can't be so difficult to fund some sort of community where people can get together and try to find a way to solve this problem.
But yeah, I think it's a growing problem. You know, I see more and more people in that position who are frustrated about it because they've written a paper. And let me be clear, like, I'm not talking about some, you know, some people with their revolutionary new quantum mechanics. You know, it's, it's typically it's like super technical stuff, some sort of data analysis or, you know, something that came out of their PhD. Yeah, you're right.
Or actually this tweet from the guy, he actually, what he wanted to do was he wanted to post his PhD thesis on the archive. And you know, he's already got his PhD, right? So how bad can it be? Why can't they just let him post his PhD thesis? Like, this is like crazy. And of course, I mean, I understand, like the archive is, you know, they have a lot of problems with whether they find people to moderate the papers. And so there are things going wrong there.
But I have even less understanding for this when it comes to journals who are actually making money with this kind of stuff. Yeah, I'm extremely interested in independent scholarship. So while the theories of everything audience has a large amount of academic researchers who watch the show, I also I want to contribute to academia in a way that's outside the academy.
And I see this as a large gap in a way that supplements the Academy rather than opposes it or overthrows it or what have you. I see the universities as doing something necessary and I'd like to help that and see where its problems are and just and fill in the gaps. But I'm not entirely sure how to do that. So anytime Sabina when you have ideas or anyone from the audience and just feel free to contact me.
I want to bring up something you said that, well, I want to bring up a critique that I've heard thrown at you that I think is unfair. And then I want to bring up something that I think you said that was unfair in one of your videos. Okay. So a critique that is thrown at you, which is something you just said, which is, look, you outlined a problem. Then you said, I don't know how to solve it. And some people are like, look, she's just bringing up problems. What are the solutions? I think that's quite unfair in the scientific method.
Your propositions just live and die on their own as to whether they're true or false. You can state a problem without knowing a solution. So in the early 2000s, when Lee Smolin came out with his book against string theory, the string theorists criticized him. They were saying, look, Lee, you're just trying to promote your own theory, namely loop quantum gravity. Peter White at the same time had his own criticisms of string theory. And then the string theorists came to him and said, look, well, you're just criticizing without putting up any alternative.
Put up or shut up is something that people say. I don't think that's fair. I think a criticism should stand on its own. It's not whether there's a solution attached to it. Then something that you said that I think was unfair was Peter White now does have his own alternative. And I remember you in a video and I don't recall the video. So I apologize. But you were lamenting some science problem and then you're saying the only people who are talking about this are me.
Peter White and Eric, and those two have their own solutions that they're trying to peddle. And I was like, OK, but that doesn't minimize what they're saying. Now, that was an offhanded remark in just a single video and you have thousands of videos. And so it's unfair of me to even bring this up because if you find if you examine anyone who has such a wealth of of content, you'll find different sentences here and there to nitpick. So I don't want this to be that I'm ill-natured or perverse in my carping.
But I just like you to to expand on that to tell me what your thoughts are and what I can totally tell you what. So first of all, it was mostly meant as a joke. So I know both Eric and Peter Lloyd.
And what I had in mind when I said this was that, um, we had a meeting and this is a really long story, which was Eric Weinstein's idea. And we all sat together with some other people, including Garrett Lacey, and it was about theories of everything. Like officially kind of the topic was my book, uh, my book lost in mouth in which I explained how you should not go about theory development.
Right. So so my entire point is like you have to have a concrete problem to solve, like you have to try to find an inconsistency to resolve and then you have to try to find a way to experimentally test it. So this is like, you know, my summary. And of course, you can disagree with that and maybe have a better way to do it. But so the irony of the of the whole thing was that I ended up with these people who do exactly what I said we should not do. Right. So we see Eric Weinstein, Peter White.
Um, this is exactly the same thing that they also do. And, and so I find this, you know, it has a certain irony to it. You know, um, I don't, you know, I, I, I understand that. When was this meeting? Uh, Jesus, it must've been before Corona. Uh, sorry, this is how the Germans call it. COVID. Uh, I don't know why the Germans stuck with this, calling it Corona. Uh, but yeah. So, um,
I think it's funny because, you know, I've tried to get people to, to understand my criticism and even the ones who are sympathetic to it don't want to actually use it. So I'm like, okay, all right, you know, whatever. So what can I say about when you said that you have
investigated climate change and then you've talked to climate scientists and you've seen how different, it's called Gell-Mann amnesia, I believe, where you see, actually, no, it's not Gell-Mann amnesia in this case. It's the opposite, where you've noticed how false scientific reporting can be in physics, but then you've actually investigated it in other domains. And so now you're just not a fan of not only science journalism, but maybe scientists
What if someone's like, okay, that's similar to a claim of racism where you've interacted with a few women or a few minorities or a few of whatever of white people and then you've had bad experiences and so you generalize to all white people or to all males or what have you rather than make keeping the claims specific and not abstracting away. So how do you disembroil between critiquing science as a whole or scientists as a whole versus just the specific claims that you've investigated?
I think we're conflating two different things now. So the one is my trust issue where I say I don't trust scientists because of what I've said and the other is what's wrong with science overall. So I think when it comes to my trust issue, you know, it's just a matter of I want to see proof. I'm not saying necessarily there is something wrong in these other disciplines.
What i want to i want to know reason why i should trust those people so i think that the comparison is not quite adequate is actually i'm exactly trying to not fall the galman amnesia. Issue in saying okay but it's only a problem this particular discipline because i think it's a systemic problem so i have no reason to assume that it doesn't also exist elsewhere.
So when it comes to the issue with science overall, I'm more relying on data, which I talked about in a recent video. So I've for a long time, I think this is also some connections that go back to Eric Weidstein, who I've known for a long time.
So it's a really long story. In any case, so I've been very interested in the economic impact of technology. And there's a long background story about how progress seems to be slowing down, which is what Tyler Cowan, I think is his name.
I think that's how it's pronounced, and other people have been working on for a long time, you know, how do you actually quantify the impact of technology on our society and at least my understanding of what they found.
is that progress has been slowing down and there are a couple of different ways to look at it. So actually, so Tyler himself seems to have recently said there seem to be some indications that the trend has been reversing and that other people have disagreed with it. So, you know, it's, you know, this is it's is its own research field. I see. And therefore, so I've been very interested in what's called scientific metrics.
or bibliometric analysis of what can you squeeze out of the scientific literature? And I actually had a research project on this. So this is another long story that I want to get. I don't want to get into. But so you don't want to get into or you want to know, I don't want to get into it because then we'll see we talking at, you know, tomorrow morning. OK. But so I know a little bit about bibliometric analysis, and I've worked on this myself.
and there have been numerous papers saying that there are indications that scientific progress is actually slowing down and you can always ask like exactly how did they measure scientific progress and everyone does it in their own way like this is an entire art discipline basically where they make up new measures
And so the reason why I find it convincing is that it doesn't really matter exactly how they did it. They always found more or less the same thing, which is that scientific progress has been slowing down since the 1960s, 1970s, which is also consistent with this economic analysis.
And then there is like the more the narrative side of this story, which is what John Horgan wrote about in his book, The End of Science, which is exactly what we started from like this impression. We're not really making progress on these big open questions like they've been open for a long time and nothing seems to be happening.
So John Horgan thinks that we've just reached the end of science, which is why his book is titled that way. And I think that that's a little bit too extreme. But I think his observation is basically correct. And he's actually written a new preface for the book at the 20 year anniversary, which was just a couple of years ago in which he says, well,
You know i've re investigated the point that i made in the book and they basically turned out to be correct you know we haven't we haven't figured out what consciousness is we still don't know what dark matters we still don't know what quantum gravity is we're still talking vague words about what complexity is and stuff like this and i think it's basically correct.
And so we cannot talk about the objections to this because they're always more or less the same. I find it a little bit tiring and you must get the same thing on social media that there are always the same objections that come from people who have never heard of the topic before and you just end up endlessly repeating the same things over and over again.
So in this case, like the typical objection is that as science gets more mature, it becomes more difficult to make progress, the progress slows down.
And what you can hold against this, where on the other hand, the number of scientists is exponentially increasing, which already makes us a little bit suspect. And then the other issue is that different disciplines, you know, if you look at something like medicine and physics, for example, like physics is much older than what people started. I mean, you know, we can talk about exactly when did medicine actually start, but because there was a lot of hocus pocus.
In the early days, serious medicine is much younger discipline than physics, which is basically, you know, thousands of years old, especially astronomy. So what sense does it make that progress and all these disciplines would slow down at the same time? Right.
If it's just something to do with the nature of knowledge itself, it's not what it looks like. It looks like it's a systemic problem with the way that we organize research. And I understand that this is not a watertight argument, but I think it's quite plausible. And at the very least, you'd think it's something to take seriously that we have to change something about the way that we organize science.
Hmm. Okay. So then it's not an argument that the foundations haven't changed. It's more about questions have remained open and not answered in quite some time. And it's been that way for a variety of fields around the same time. Yeah. So that's entirely right. So my biggest problem is not that these questions have remained open for such a long time. But
that we're not getting anywhere like so we're just doing the same thing over again and it seems to be a systemic problem in in all fields so it just feels to me like something isn't quite right does it make sense yeah the only field i don't see this in i don't see someone saying that there's a crisis in crisis in physics crisis in ecology
Meaning crisis everyone's in a crisis except computer science. Yeah, right and the foundations of computer science hasn't changed since the 40s since even before physics since Turing in church It's the season for all your holiday favorites like a very Jonas Christmas movie and home alone on Disney plus I don't

Now there are unanswered questions about the limits of computability and complexity issues but those are like machine code questions that are close to the base but they don't question the base. Yeah so actually I think one could make a fair point that pretty much all the progress that we see in science overall has actually been driven by
Maybe not exactly computer science but computer science in the in the general sense extended to technology technological applications you know data analysis and so on and so forth i mean certainly like in physics itself you know if you i mean i remember when i was a student if you had an integral that you could not solve
That was not in the table. That was the end of your research. You were like, okay, that's it. Can't solve this. It's funny. Like, and this is just, this problem has just totally evaporate, right? You're like, okay, we can't solve this integral. We put it into computer problem solved. Uh, and so, uh, and this is like such, such a trivial thing, almost, uh, how computing power has made such a big impact, uh, in physics.
And it's certainly also also another disciplines like if you look at medicine, just data analysis, if you look at MRI, fMRI, all this stuff, you know, it's you need to analyze this data, you need computers.
Right. So I think this is what it's driven by. But then you can also ask what made this progress in computer science possible? And I would say, well, ultimately, it's all physics, right? You need to know what a semiconductor conductors, how do they work, what's a band gap, and all this kind of stuff. And you know, I know there are people who are arguing like, this is not like, historically, it's not how it happened.
It was more an accidental thing. Some people were tinkering around with stuff here and there. It's not like they sat there and developed a theory for semiconductors and then they build it. This is not what happened. But I still think like if you look at it from a, you know, from a constructive point of view in the sense of how does science build up, it goes back to to our understanding of physics, you know, of materials, of electricity.
What we're doing right now is that we're trying to get out of the science that we have already discovered what we possibly can. So we're making computers smaller and smaller and there's
A lot left to do. Actually, John Hogan makes it very clear in his book that this is not what he's talking about. So there's a lot of stuff that you can build up on the science that we know already, for example, in computing and robotics and so on, which kind of seems to be the next thing. The next big thing that will come knocking at the door seems to be a robot. Yes.
And so there's a lot of research left to do but what he's concerned with and what I'm also concerned with are these big new discoveries about the world and so of course I'm as a physicist I'm very opinionated about these things but I think that
physics and especially the foundations of physics are super important discipline because it's where we get the deepest insights about nature. So if we don't make progress in the foundations of physics then sooner or later progress in all other disciplines is also going to run dry. And so this sounds a little bit bombastic and there are a lot of people who would disagree with this. You probably know this entire argument about what we actually mean by fundamental.
Is biology any less fundamental than physics? I would say yes, but biologists might disagree.
In any case, I think that if we really want to make progress as a society as a whole, we need to make progress on the foundations of physics in the sense of actually discovering some new phenomenon, maybe understanding quantum mechanics, maybe it's quantum gravity, though I personally think this is somewhat unlikely, but anything, something really. Yes.
So you don't see your work on super determinism as just contributing to the useless papers that are produced? No, of course not. Even if that was the case, I'd never admit it. No, but look, we already talked about this. I overthink everything. If I make a joke, I read like three books and I analyze
joke structures as you say and I think about the subtext and I try to find the most the most punchy phrase and which word word comes in which order how do I start what's what's oh that's interesting great right and and so this is also more or less how I've approached the question of what do I make my research on this is why I wrote my first book it was trying to figure out what should I spend my time on because there's only so much time in my life so what's the most promising thing to work on
And I've tried to take my own advice very seriously, maybe not totally successful, but at least I've tried. And so I've tried to not work on the problems that I think are pseudo problems, but I've tried to focus on the problems that I said are real problems where time is well spent. Now, the issue is that I couldn't get funding to work on those.
And this is why I'm now in the position that I am, where I'm funding my own research by making videos on YouTube. And I rely a lot on people supporting me, people on Patreon, people who join my channel, who I'm super, super grateful for because otherwise it wouldn't be possible.
And so the reason i ended up working on the super determinism stuff is that i arrived at the conclusion like that the best way to make progress is to figure out what happens.
In a measurement and quantum mechanics and why this particular problem because we know it's something that is in the measure of a range like it's literally a measurement process like it happens in the laboratory all the time and it quite plausibly has a relevance for practical applications.
Exactly because it's in a parameter range that is easily experimentally accessible that we actually already access with devices that we build. Do you have any new ideas about quantum gravity? About quantum gravity? No, because I've been focusing on this measurement issue. So I've eventually worked kind of
Yes, but so I know this this now sounds very confusing. So I've for some while suspected that maybe the two problems are actually related, partly because as you know, Penrose has this idea that actually the collapse of the wave function is somehow caused by gravity. And I'm not super happy with this particular model of how it works.
Great.
I don't know how much you want to hear about it because it really gets a little bit. Yeah, I would love to hear about it, especially if you're in collaboration with Tim Palmer or if it's different than this. No, he doesn't like it. So I don't know. So we talk about it and he gives me good feedback, but I think he doesn't really like the idea. OK, so it goes back to a paper which I wrote like 10 years ago or something, which is kind of kind of vaguely called
possibility to solve the problem with quantizing gravity or something. What I was trying to point out in this paper is that just on purely logical reasons there is a possibility to solve the problems with quantizing gravity that no one has previously talked about.
uh which is that uh all these problems which we have if we perturbatively quantize gravity and then you know um the the theory produces all these infinities uh it's not renormalizable and all these problems then we need string theory or loop quantum gravity uh they appear at really high energies which we haven't tested yes and so in particularly we don't know that
Quantum physics itself actually works the same in this energy range as it does at low energies. So Isa, you know what we can do is that if we go to these high energies where perturbatively quantized gravity becomes problematic, we just say quantum effects go all the way. So we go back to classical physics.
And so you see then these two problems suddenly become the same problem. That's the reason we can't quantize gravity is that we don't understand what quantum effects go in a measurement. Yes. And once once you make this connection, you have a method of quantifying where the deviations from quantum mechanics should occur, because now you can estimate that it should come with the size of the
quantum gravitational effects which don't happen if that makes sense. So you say it has to happen in this range for those quantum problematic quantum gravitational contributions to go away.
And so even if you don't exactly know how it works, like what's the exact mechanism that makes it go away gives you a way to estimate the range in which it should happen. And I've done this. And now the depressing part of the story is that I couldn't think of any experiment that would actually access this range. So which is unfortunate. So you're part of the problem. Well,
Well you see what i could do now is i could come up with a reason for why this is accessible with the next experiment that i going to build somewhere and that's exactly what i don't want to do and so now i have this problem case i finally have found a way to do it i found a way to make this estimate estimate.
So I'm confused about the proposal. So you're saying that at high energies,
quantum effects may diminish because we have some problems with quantum gravity only at high energies like there's low energy combinations of gr with qft okay and then you're making a connection between that and the measurement problem but the measurement problem occurs at low energies as well no yes that's exactly the right question to ask because when i was talking about high energy
That was a very vague way to explain the idea. So the question is exactly what is the quantity that you need to compute an energy. So first of all, normally if they talk about the high energy expansion, it's not actually energy, but it's something like momentum transfer. So it has the scale of an energy. But
first of all you want to use something that's actually Lorentz invariant so energy is already bad and so then you can think about should we use math but math doesn't really make sense either and so
I've eventually come up with a way to do it in the path integral because that fits very well together with the paper that I brought several years ago and you can then estimate the contribution from this
Quantum mechanical term in the path integral, which we know how it looks like. So this is again, you know, this is the nice thing about it. We know how this contribution looks like to the normal, you know, term without the quantum gravitational contribution. You can ask, well, when does the crossover happen? Like when does this term have approximately the same size as this other term?
And so it's it's more complicated than energy. It's something like a space time integral over the stress energy momentum tensor coupled to the metric. If that makes sense, something like that. Yeah.
I'd be remiss if I didn't mention the profusion of papers produced, which was covered by The Economist. They have an article explaining this issue simply and concisely called, scientific publishers are producing more papers than ever. They confirm what you've been saying, at least from a financial incentive standpoint. They're saying that the reasons are based on business models or subscription fees. However, they brought up special issues as another reason, and I haven't heard you mention that before.
Well, yeah, I mean, the special issue issue is also something that I've talked about. So basically, the issue is that publishers make money by selling stuff. You know, they sell subscriptions to journals or books or special issues. But they don't want to spend the money to produce the content.
And so they've caught into life these special issues where they recruit was called a guest editor and the guest editor invites people to write contributions to the special issue on some topic and then they publish this special issue and they basically sell it to libraries.
I don't want to diss all special issues. It started from a good idea to give some space for rapidly emerging fields where you don't have a lot of people who know each other. You want to collect all these people in one issue.
A new field has something to start from. It's the same idea as with the rapid response workshops that they do in some places, if you ever heard of this. You know, there's a new issue that is emerging in the scientific community. You want to give people some networking opportunities. They need to get to know each other. They need to develop their new language. And so the special issues came out of the same idea.
But then what's happened is that some certain publishers have abused this to cheaply produce content and then make money by selling it. And this has certainly contributed to the number of publications rising. I haven't read the article in The Economist, but I think that's correct. I'm not actually sure that this is like the biggest issue. So this has been going on for at least
I don't know since before COVID, they started to get it right. And so what I've seen in the past three years or something is that everyone knows like this is basically, you know, it's not really sound stuff to do. And more and more people just don't want to want to have anything to do with it. So I would expect that this is actually already declining at this point. So my ending question is a meta question.
Given that you're much more skilled at this than myself, what should we title this video? Oh dear. Sabina Orsenfelder talks a lot of bullshit. I'm pretty sure of this. I have to warn you know what's going to happen. You're getting flagged by YouTube for my profanity. Yeah.
I don't know, I guess pick the most interesting one. I'm not sure if it's good to have my name in the title if that is more attractive or more repulsive. But I guess there's no way around it, right? I mean, otherwise, how people supposed to know what's in the video. So, okay, one that occurs to me is the stagnation in physics, rather than the crisis in physics. Now, if I wanted to be more galvanic, I could put the crisis in science. But what would you say?
I may just take what you're going to say here and put it on and people will see.
you know, related, but not exactly the same in terms of words, like maybe what's going wrong in physics, or maybe I have already used this as a title. So you better take this. Yeah, I don't want to compete with the great Sabina. Yeah, well, you get the idea, you know, just don't use exactly the same words that other people have already used, because people might think of where it's just the same stuff all over again. Mm hmm.
Why string theory is correct.
Yeah, but then people will feel feel misled, right? Of course. Okay, it was a joke. Okay, right. Yeah, that's my death. Okay, first of all, by the way, that's a joke. And then secondly, that's my definition of clickbait is when it not just something that is peek into but that it doesn't deliver. Yeah, right. Exactly. Right. Honestly, I think when people say that my videos are clickbait, what they're referring to the stupid photos of me with the facial expression.
on the thumbnail for which i have a very simple explanation is that i don't know what else to put on the thumbnail you know if you you must know this problem you talk about super abstract stuff what the hell do you put on the thumbnail other than yourself and this is why i have collected 100 photos of me making silly faces just so there's something to put there
So the way that it works, just if you want some behind the scenes for our channel, the way that it works is that the full podcast that are one hour to three hours long, the full ones, they have my minute attention on the title and the thumbnail titles. There's two different types of titles for people who are unfamiliar. There's the YouTube title and then there's what we call the thumb text. So we play around with different combinations and we test some, but it does have my personal touch.
but then we also take out clips from those because not everyone has the stamina or want to watch a five hour podcast so we take out 10 to 15 minute clips and that's a marketer i have a marketing guy a fantastic marketing guy who who's in charge of daily clips and he does that and i tell him just don't as long as it's not it doesn't say
Penrose reveals his theory.
like we just tested a title called the hidden potential of the brain and it works better than the potential of the brain but i and my even the marketer himself didn't like that and so we just went back to the potential of the brain but anyhow he's in charge of the daily clip titles and thumb text whereas the full podcast get much more of the of this the fact that i'm even asking you getting your actual opinion it has my fingers in it
Yeah, so you must also have tried this, like there are a variety of AI plugs that you can use to generate titers. And they're so hilariously bad. Like it's hidden is one of those words and reveals and, you know, blasting the myth of the something or other with lots of capital. You don't want to miss it. Yeah, exactly. Right. Yeah. Yeah. It gets cringy to me. Maybe they would work.
Yeah, I can't even get myself like, so this is something I've discussed with my agency, like there are a lot of people who put capital words in the title. And I've tried this a few times, but every time I look at it, I'm like, I just can't do it. And I remove it again.
Yeah, OK, so we still don't know what you're going to call the video. Yeah, so I may say what's wrong with physics or something like that. I think that what you said is correct and I'm going to blame you. So if I get criticized for being clickbait, you can blame me. Yeah. Yeah. Yeah. You know, I find it interesting that the word clickbait, you know, it's it's so overused at this point is pretty much meaningless. So I remember a time when clickbait was
It was a title that you actually you have to click on it to find out what it even was about. Right. So it's like stereotypically this thing. She woke up for her wedding day. You won't believe what happened next. Like so this is like the stereotypical click bait type or this grandmother in Utah found that toothpaste does exactly that sort of thing. And so now we have like some sort of
click baitish title that people don't even recognize as click bait. So like, for example, there was a video which kind of titled the man who killed the most people in history. And you maybe, you know, who's video this was like, but you have to click on the stupid video to figure out that it was about the guy who put Latin gasoline or something. Okay. Right.
so and i would call this is like stereotypical clickbait because you have to click on it to know what it even is about but i think people don't register this stuff as clickbait which i find kind of interesting so it's just an observation that i think the
I wouldn't call that clickbait. The reason why is to me the content has to have a mismatch between itself and then the title. So in that case, it sounded like the person delivered. They must have some reason for suggesting that person killed the most people. I thought it was going to be Stalin or Hitler or someone who dropped the bombs. No, no.
I didn't really look into it. It's quite I guess it's probably correct. Yeah, so you see I understand I wouldn't use the word clickbait in that sense because the examples that we we just mentioned like the stereotypical clickbait we like we really love this five everyday hacks or whatever. They actually do deliver the stuff you just have to click on it to figure out that it's some super dumb
Stuff you know yeah yes yes yes so uh whatever uh okay all right sounds like a great place to stop lovely to talk to you yeah lovely to talk to you and it's great meeting you in person oh yeah yeah yeah uh we should do it again or somewhat
Don't go anywhere just yet. Now I have a recap of today's episode brought to you by The Economist. Just as The Economist brings clarity to complex concepts, we're doing the same with our new AI powered episode recap. Here's a concise summary of the key insights from today's podcast. Welcome to our deep dive into this fascinating conversation. It's between Kurt Joe McGull, host of Theories of Everything and physicist Sabine Hassenfelder. Yeah.
and you know you've probably heard people talking about a stagnation in physics these days and that's what they tackled head-on. We've got their conversation as our source material here and it's really packed with insights about you know their physics stands today and what the future may hold. What I think is so interesting is Kurt you know he really dives deep into the mathematical side of things. He actually kind of pushes back
on some of Sabine's points while agreeing with others. So it's this really cool dynamic. Yeah, they start right off the bat tackling, you know, is physics in a state of crisis or is it stagnation? And Sabine, as you probably know, prefers the term stagnation. And she uses this cool analogy of physicists running on a treadmill, lots of effort, lots of papers, lots of, you know, conferences and things, but no real movement forward. And she's talking specifically about the foundations of physics.
You know, those big questions that we've been puzzled by for decades now. Dark matter, quantum gravity, the interpretation of quantum mechanics. So she's saying it's not that physicists aren't working hard. It's that the current approaches or methods just aren't yielding those breakthroughs. Yeah, I think that's really the core of our argument is that despite decades of research, we haven't had any significant shift in our understanding in these fundamental mysteries.
But Kurt, who's no stranger to complex theories himself, offers a slightly different perspective. He does. He's very much interested in the mathematical intricacies of some areas of physics that Sabine considers less fruitful. Things like soft theorems or asymptotic symmetries or gauge-gravity dualities.
And he acknowledges that those haven't led to new fundamental physics yet, but he sees this mathematical elegance as potentially a sign of something deeper. So they're both wrestling with this question of progress, but they're coming at it from slightly different angles. Yeah, I think that's a great way to put it. Yeah, and this leads to this really interesting discussion about, you know, what even constitutes a real problem in physics. And Sabine argues that some problems might actually be
Pseudo problems right meaning nature might just be that way right even if it doesn't fit our current Theoretical frameworks. Yeah, so can you give an example of that? So she points to the strong CP problem? Okay, where there's this certain kind of symmetry violation that should exist theoretically But it doesn't seem to show up in our observations of the universe. Okay, and she says, you know, oh
Maybe this isn't really a problem to be solved, maybe this is just a feature of the universe. She's challenging this idea that we need to always strive for these really neat, elegant explanations. I think that's right. Yeah, she pushes back against this notion of naturalness, which has been a guiding principle in theoretical physics for a long time. But as she points out, naturalness has led to a lot of incorrect predictions, things like
The expectation of supersymmetry at the Large Hadron Collider, which hasn't panned out.
And this ties into her broader critique about the way that research is conducted today. Oh, right. The systemic problems with academia. Let's unpack that a bit. One of her main concerns is this overreliance on short term grants, which forces researchers into this, this kind of publish or perish mentality where they're constantly, you know, chasing funding.
turning out papers right instead of you know pursuing these long-term risky projects that might lead to really groundbreaking discoveries so it's almost like the system itself discourages boldness yeah that's what she's arguing and it and it creates these sort of self-reinforcing bubbles where researchers get stuck in specific subfields yeah because that's where the funding is that's what's expected for career advancement right so what's the alternative does she offer any solutions
She brings up this idea of a scientific underground, which is this community of researchers that are operating outside of traditional academia and are free to pursue their passions without the constraints of grant deadlines and institutional pressures. Oh wow, that's exciting. It's almost like this band of rebels pushing the boundaries. She definitely sees it as a potential source of fresh ideas and new innovative approaches, but she also acknowledges that these independent researchers face many challenges.
particularly the lack of access to resources and community support. She shares a story about a researcher who couldn't even post their PhD thesis on ArxFIF, which is usually a pretty standard practice. And that really highlights the barriers that they face. Absolutely. And this leads into another really key point in their conversation, which is this issue of public trust in science. And Sabine argues that
You know, these systemic problems within academia, this sense that things are kind of stuck actually contributes to the growing distrust in scientific expertise. I think that's a really fascinating connection. Yeah, and so she's saying by acknowledging these problems, being upfront about them, the scientific community can start to rebuild that trust. That's exactly what she's arguing, this idea that transparency and a willingness to acknowledge limitations
are crucial for regaining that public confidence. It's not about pretending everything's perfect, but it's about showing that the process is robust enough to handle criticism and self-correction. And this is where they bring in a broader perspective and they start talking about whether this slowdown in progress is actually happening across multiple fields, not just physics. So they discuss insights from economics and this field of scientometrics, which studies the patterns of scientific publishing and discovery.
They even reference work by Tyler Cowan and John Horgan, who have argued that we are seeing a general slowdown in scientific progress across the board. So it's not just physicists who are feeling this. It seems not to be stagnation. And what's really interesting is they push back against this common counter argument.
that progress naturally slows down as fields mature. They point out that we're seeing this slowdown across disciplines of varying ages. And we can't ignore the fact that the number of scientists worldwide has been increasing exponentially. So if it were simply a matter of scientific maturity, wouldn't we expect to see at least some fields
Right, so it's not just that we plucked all the low-hanging fruit. Yeah, and they seem to point towards the structure of scientific institutions themselves as a potential factor. Right, and this brings us back to these issues that we talked about. The publish or perish, the short-term grants. The over-specialization. Yeah, and so it's like,
We've inadvertently built a system that discourages the very creativity that drives scientific progress. And that's why both Kurt and Sabine see this conversation as so crucial. They believe that acknowledging these systemic challenges
It's about recognizing that the way we organize and fund the scientific research has a profound impact on the types of questions we ask and the types of discoveries we make.
How we approach science shift away from this hyper competitive short term focus collaborative long term vision it's a challenging prospect but it's one that i think they both believe is worth taking on express hope that by bringing these issues to light.
they can spark new conversations and inspire the next generation of scientists to think differently about how we pursue knowledge and understanding. So it's not about giving up on science. It's about being, you know, realistic. It's about recognizing the limitation, recognizing the limitations and being willing to imagine these new possibilities. Exactly. It's about embracing that spirit of inquiry and exploration that lies at the heart of science, this drive,
to ask big questions, to challenge assumptions, and to really push the boundaries of what we know. And, you know, maybe as Sabine suggests, part of the solution lies in fostering a community, one that values a wider range of perspectives, both within traditional institutions and, you know, and that scientific underground. It's a really inspiring vision. It is a future where scientific progress is driven not by
It's a real dilemma. On the one hand, we want researchers to share their findings widely.
But on the other hand, we don't want to incentivize rushed or superficial work. Yeah, it's this tough balance. It's a delicate balance. And they both highlight the rise of special issues in journals as a particularly concerning trend.
And while these special issues can sometimes serve a legitimate purpose, like showcasing a rapidly developing field, they've also been used by some publishers to just churn out content quickly and boost profits. So there's a potential conflict of interest there. That's a concern. If publishers are prioritizing profit over scientific rigor, that could have a detrimental effect on the quality of research. And they both see this as part of this
larger systemic problem within academia, this pressure to publish as much as possible, often at the expense of deep, thoughtful inquiry. And it's not just about the quality of research. It also ties back into public trust. Exactly. If people feel that the research is being driven by financial motives rather than genuine pursuit of knowledge, it can erode their confidence. Exactly. That's why Sabine emphasizes transparency and accountability within the scientific community.
Okay.
The scientific process, despite its flaws, is still the best way to understand the world. Absolutely. It's about recognizing that science is a human endeavor with all the complexities and imperfections that come with that. Absolutely. And having those honest conversations about the challenges and limitations both within the scientific community and with the public. Speaking of challenges, let's go back to this idea of a scientific
It seems like a catch 22.
It is. You need resources and support to conduct research. Right. But you need to have already done research to get those resources and support. Exactly. And this is where they see the need for a fundamental shift in how we think about and support science. Yeah. They believe we need pathways for people to engage in scientific exploration, regardless of their institutional affiliations. So it's about fostering a vibrant scientific ecosystem. Precisely. One that values a wider range of perspectives and approaches.
And that leads us to the final part of our deep dive, where we'll delve into the broader implications of this slowdown and explore what the future might hold for scientific discovery and innovation. Welcome back to our deep dive into this really insightful conversation with Kurt Jemungel and Sabine Hassenfelder. We've covered a lot of ground from super determinism to the challenges in scientific publishing today. But I think now let's tackle this big question of
the potential slowdown in scientific progress.
But also a bit unsettling. It is unsettling because we tend to think of science as this ever-advancing force constantly pushing the boundaries of knowledge. Right. What if we've hit a plateau? What if the pace of groundbreaking discoveries is actually slowing down? It's a question that has been ruled by others, you know, Tyler Powen, John Horgan, who you mentioned earlier. And what I find interesting is Kurt and Sabine don't dismiss this idea. They engage with it thoughtfully. They bring in data
that suggests a potential decline in groundbreaking discoveries since the mid-twentieth century. That's pretty wild. And they also challenge that easy explanation, right? This idea that progress naturally slows down as fields mature. Exactly. They point out that this slowdown seems to be happening across disciplines regardless of their age. And we can't ignore the fact that the number of scientists worldwide has been growing exponentially. So if it were simply a matter of scientific maturity,
wouldn't we expect at least some fields to still be making rapid progress? It seems like there's something else going on. And they point towards the structure of scientific institutions themselves as a potential factor. Yeah. They bring us back to the issues that we talked about earlier. The publish or perish pressure, the short-term grant cycles, the over-specialization within fields. You know, it's as if we've created a system that rewards incremental advancements over bold, risky leaps into the unknown.
Right. It's almost like we've accidentally built a system that stifles creativity, which is supposed to be the engine of science. That's exactly right. And that's precisely why both Kurt and Sabine see this conversation as so crucial. They believe that acknowledging these systemic challenges is the first step towards finding solutions. It's about recognizing that the way we organize and fund scientific research has a profound impact on the kinds of questions we ask and the types of discoveries that we make. It makes you wonder
Do we need a fundamental rethink? Like how do we approach science? A shift away from this hyper competitive short-term focus and toward a more collaborative long-term vision? It's a tough challenge for sure, but it's one that Kurt and Sabine believe is worth taking on. They express hope that by bringing these issues to light, they can spark new conversations and inspire the next generation of scientists to think differently about
how we pursue knowledge and how we pursue understanding. So it's not about giving up on science or being disillusioned? No, it's about being realistic. It's about recognizing the limitations of our current systems and being willing to imagine new possibilities. It's about embracing that spirit of inquiry and exploration that lies at the heart of science. The drive to ask these big questions, to challenge assumptions
and to push the boundaries of what we know and what we understand. Absolutely. One that values a wider range of perspectives and approaches both within traditional institutions and within that scientific underground that we talked about earlier. It's a really inspiring vision, a future where scientific progress is driven not by competition and individual ambition, but by collaboration, curiosity, and a shared commitment to unraveling the mysteries of the universe. Yeah, that's a great point to end on, I think.
We've covered so much in this deep dive, questions about stagnation, this mind-bending world of super determinism, the challenges facing scientific publishing, and ultimately the very nature of scientific progress itself. And that's what's so great about this conversation between Kurt and Sabine. It's really sparked so many new ideas and new lines of inquiry. We've only just scratched the surface here though. Yeah. You know, we've offered a glimpse into this really fascinating conversation that is full of insights and provocations.
Now it's your turn to ponder these ideas to explore these questions further and maybe even challenge some of your own assumptions about the world and how we understand it. Yeah, keep that scientific spirit alive. Keep asking those big questions. Stay curious and never stop exploring.

Also, full transcripts will be placed there at some point in the future. Several people ask me, hey, Kurt, you've spoken to so many people in the fields of theoretical physics, philosophy and consciousness. What are your thoughts? While I remain impartial in interviews, this substack is a way to peer into my present deliberations on these topics. Also,
