   > You need to train two grad students, two AI grad students to go at... Okay. So if two AI grad students could have a conversation and figure something out, what is the one thing in physics that you just wish that they would just give you the answer to? Well, I would like to know the true nature of time. To me, that's the big physics question. I'd like to understand whether quantum mechanics is an effective theory that works at one scale,

   Prof: So this is a very exciting day for me, because today, we're going to start quantum mechanics and that's all we'll do till the end of the term. Now I've got bad news and good news. The bad news is that it's a subject that's kind of hard to follow intuitively, and the good news is that nobody can follow it intuitively. Richard Feynman, one of the big figures in physics, used to say, "No one understands quantum mechanics." So in some sense, the pressure is off for you guys, because I don't get it and you don't get it and Feynman doesn't get it. The point is, here is my goal. Right now, I'm …

I'd like to understand whether quantum mechanics is an effective theory that works at one scale, but there's a deeper description that Einstein was hoping to one day find but never did that might be underneath it all. I want to really understand how quantum mechanics and gravity

   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 …

   Prof: All right, today's topic is the theory of nearly everything, okay? You wanted to know the theory of everything? You're almost there, because I'm finally ready to reveal to you the laws of quantum dynamics that tells you how things change with time. So that's the analog of F = ma. That's called the Schrˆdinger equation, and just about anything you see in this room, or on this planet, anything you can see or use is really described by this equation I'm going to write down today. It contains Newton's laws as part of it, because if you can do the quantum theory, you can always find hidden in…

   Professor Ramamurti Shankar: This is a first part of the year-long course introducing you to all the major ideas in physics, starting from Galileo and Newton right up to the big revolutions of the last century, which was on relativity and quantum mechanics. The target audience for this course is really very broad. In fact, I've always been surprised at how broad the representation is. I don't know what your major is; I don't know what you are going to do later so I picked the topics that all of us in physics find fascinating. Some may or may not be useful, but you just don't know. Some of you …

   A very good way of putting it. And the result is a sort of induced, what do I call it? Induced cringe, or something. The students of quantum mechanics are trained not to ask those questions. And if you're trained not to ask certain questions, that has an effect on your worldview. It has an effect on the culture in physics, because students think that they're the only one who worries about this. And in fact, they all worry about this. They're the ones that are studying physics in order to understand the world, always worry about this. And they learn this language of substituting ideas about abs…

   So, this will remind you that physics is, after all, an experimental science and you will be able to see where all the laws of physics come from. So, if you're going to take it, you should take it at the same time. Yes? Student: Could you please talk about when you expect [inaudible] Professor Ramamurti Shankar: Ah, very good. This is a calculus-based class and I expect everyone to know at least the rudiments of differential calculus. What's a function, what's a derivative, what's a second derivative, how to take derivatives of elementary functions, how to do elementary integrals. Sometime lat…

   And of course, there's trigonometric identities you know from high school. Pages and pages of them, so no one expects you to know all those identities, but there are a few popular ones we will use. All right. Anything else? Yes? Student: This may be a bit early, but when will we be having our Midterm? Professor Ramamurti Shankar: Yeah. Midterm will be sometime around 20th of October. I have to find out exactly the right time. We have 24 lectures for this class and the first 12 roughly will be part of the Midterm, but after the 12th lecture I may wait a week so that you have time to do the prob…

    Physicists like, especially after a certain age, to look around the intellectual landscape and see other fields of inquiry that are not physics and go, I could do that better than they can. I'm a physicist. How hard can it be? This is not what I'm here to do. I am not going to give you definitive final answers about any of these things. But I do think that there is a common vocabulary, a common ground in which we can discuss these various issues. And that's really what I'm here to talk about. So I want to start with a simple question that is uh related to physics but one that also is related t…
