   > don't. That's why. Why is the speed of light the same for all observers in all inertial frames? because the trace of an end cycle is an end cycle when I take so it's always the same speed one state per

   I expect you to get a speed c/2. But you keep getting c. You go three fourths of the velocity of light; you still get the velocity of light. That is very contrary to what we believe. In fact, that's in violent opposition to this law here. If this V were not a bullet but a light beam, suppose for me traveling at a speed c and you're traveling to the right at speed u, you should get c - u. That's the inevitable consequence of Newtonian physics. And you don't get that. And that was a big problem. So, people tried to fix it up by doing different models of ether, none of which worked. And nobody kn…

   Where you can have a spin state which is shared by two observers or two people. Let’s call them widely separated. And you know what? The total spin each one has a spin half particle, which has come from a spin zero initial state. And so they have to be opposite each other. Not one of the individuals measured the spin in some direction that instantly makes it the opposite, actually worse than instantly. It goes backwards in time along the past lightcone and the other ones is fixed by the measurement made by the one and the other one. If that other one could ascertain what the state was, you wou…

   Maxwell says there is something called the speed of light. It is the speed at which waves in the electromagnetic fields move. And naively, you look at the equations and everyone measures the same value for the speed of light. It's a constant of nature. How can it possibly be the case that everyone measures the same speed for light even if they're moving with respect to each other? So for a long time, for decades, people, physicists, bashed their heads against this problem. They came with very elaborate schemes to get rid of it. And it was Einstein, Albert Einstein, in his great paper in 1905, …

   I wanted to begin with a, I don't know, a pet peeve of mine that I think you also agree with. When it comes to quantum mechanics, unlike any other theory that we discuss, people use this word "interpretation." The interpretations of quantum mechanics. And to me, as we'll get into it, the interpretations are not interpretations. They're different theories. And some of the interpretations don't even qualify as a complete theory. And so that just seems to be a complete misnomer in the way we describe these things. - I couldn't agree more. And I got this view from Bryce DeWitt, who was my supervis…

   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…

   > 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, 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

   So isn't it basically hiding within it, all of the weirdnesses that we sort of have a more blatant in-our-face description of in the Schrodinger approach? - Well, the two approaches are equivalent. It's just that one of them makes it easier to get the results of an experiment, and the other one makes it easier to get how the result comes about. So in practice, I use both, and I still use both, in practice, even though I advocate only the Heisenberg picture for understanding quantum theory. One of the advantages of trying to find out how the observed phenomena come about, is not only that we wa…

   Well, Newton didn't try to describe things moving at speeds comparable to light. He dealt with what problem he could deal with at that time. So, it's a law that has a limited domain of validity. You can always push the frontiers of observation until you come to a situation where the law doesn't work. But the specialty of relativity doesn't also work all the time. If the mass becomes very tiny, it becomes of atomic dimensions, then you need the laws of quantum mechanics. That's wrong too. So, things work in a certain domain and sometimes you abandon the formalism; but don't rush to do that. In …

    We still lack any consensus about what one is actually talking about as one uses quantum mechanics. There is a gap between the abstract terms in which the theory is couched and the phenomena the theory enables each of us to account for so well. Because it has no practical consequences for how we each use quantum mechanics to deal with physical problems, this cognitive dissonance has managed to coexist with the quantum theory from the very beginning. The absence of conceptual clarity for almost a century suggests that the problem might lie in some implicit misconceptions about the nature of sci…
