   What would it take for me to give up on string theory? I wish I could sit here and say in 5 years, there's going to be an experiment at such and such a collider or in 10 years, there's going to be an observation by such and such space station or space observatory. And if it doesn't come out in a particular way, I'll give up on string theory. I can't say that. Nobody can. And the reason is, I think as many of you know string theory has not yet developed to a point where we can make the kinds of definitive observational or experimental predictions that certainly we hoped we'd be able to do when …

   No in fact probably a 100 top physicists today want to start from the whole and derive the parts because they have understood that trying to go the other way gives you know leaves you empty-handed. Yeah. In fact, you know, string theory which tried to explain reality from the parts which are strings that vibrates [snorts] did not succeed. And you know, it took about 80 years of hard work. At one point 90% of the, you know, the physicist, the theoretical physicist were working on string theory. >> They didn't get anywhere. So that's that's telling you that no, we have to start with the wh…

   You all lift your hands up, then I follow you. You follow this perfect sine. Then you let go. What do you think will happen then? What do you think will be the subsequent evolution of the string? Do you have any guess? Yes? Student: > Prof: It will go up and down, and the future of that string will look like cosine(pxvt/L). Look at it. This is a time dependence, that t = 0, this goes away, this initial state. But look what happens at a later time. Every point x rises and falls with the same period. It goes up and down all together. That means a little later it will look like that, then it w…

   Brian Green, welcome to the show. Thank you so much. The Elegant Universe turns 25 this year, just like me. Uh, I wish I could say that about myself. I'd like to get into what's changed, where we're at, but I think it's going to require starting with the question that I'm sure you've never been asked before. What is string theory? Yes. Uh, good question. There are a number of ways of framing what string theory is about, but perhaps from the largest perspective, it's an attempt to realize a dream that really begins with Albert Einstein, which is this idea that we have a single universe. So, we …

   How do we know that this isn't just pure mathematics? And that would take us into a wonderful conversation along the lines of the material that we just discussed. So yeah, I think he would warm to these ideas pretty quickly. Do you think we're sort of in the realm of philosophy here? One of the criticisms that I see of string theory as somebody who doesn't understand the first thing about it is that because of this lack of experimental data, you can say that in principle it could be tested. But there are all kinds of philosophical theories that in principle we could test. Ideas about personal …

   One is to tell you a little bit about how you get there, and for those of you who say, "Look, spare me the details, I just want to know the answer," I will draw a box around the answer, and you are free to start from there. But I want to give everyone a chance to look under the hood and see what's happening. So given an equation like this, which is pretty old stuff in mathematical physics from after Newton's time, people always ask the following question. They say, "Look, I don't know if I can solve it for every imaginable initial condition." It's like saying, even the case of the oscillator, …

   But nevertheless, every term here is explained, briefly. It takes a year long quantum field theory course in graduate school to get the details, but at least say what every term means, including the i for example and including the k less than lambda. What you don't see are causes, purposes, or reasons why. It's just Laplacian calculation over and over again. This is the modern version of what you need to program into Laplace's demon so that starting from the position and configuration of the world at one point, it can find out what will happen next or what happened before. The final criterion …

   Prof: So, I've got to start by telling you the syllabus for this term--not the detailed one, just the big game plan. The game plan is: we will do electromagnetic theory. Electromagnetism is a new force that I will introduce to you and go through all the details. And I will do optics, and optics is part of electromagnetism. And then near the end we will do quantum mechanics. Now, quantum mechanics is not like a new force. It's a whole different ball game. It's not about what forces are acting on this or that object that make it move, or change its path. The question there is: should we be even …

   And that's really important because if you put forward an idea that's meant to be scientific, but someone can establish you can't possibly in any way, shape, or form ever test that idea, then it's hard to see that it fits within the categorization of science. But if you put forward an idea which at least in principle you could test if you had the right equipment, then to me if it solves certain key problems, if it advances your understanding theoretically of things like black holes and the big bang and the nature of space and the nature of time, which is what string theory does, then it's abso…

    > well, where did that fifth order, where was the impetus for the second order coming from? Something like that. Something like that. You always, in order to generalize a theory, you must understand the to be generalized theory first at a deeper conceptual level. And there that's already ambiguous because you can look at things at different conceptual levels, right? You can describe, take gravity. Okay. High school question. High school teacher asks
