Einstein's General Theory of Relativity | Lecture 3

In this lecture, Leonard Susskind continues his discussion of Einstein's theory of general relativity. He also gives a broad overview of the field of tensor calculus and it's relation to the curvature and geometry of space-time.

This Stanford Continuing Studies course is the fourth of a six-quarter sequence of classes exploring the essential theoretical foundations of modern physics. The topics covered in this course focus on classical mechanics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

That guy... Argh THAT GUY! Every question he asks causes excruciating pain.

[ASKaPHYSICIST]

I disagree; if physics was just applied maths, you could say the same about science in general. I would say maths is a tool to do physics, but can not be used as a substitute for understanding the underlying principles.

As for the arts major, his head would explode.

This intrest's me very much, even though i am a sophmore in highschool. Physics come naturally to me...i dont know why

[hoangvuhv2003]

c'est tres bien

I like the way Leonard Susskind has adapted to those questions, he seems to have developed the ability to ignore the annoying guy lol. 18:06

@SxeD4ve Naw naw naw, one should feel free to argue. Even geniuses can be wrong. But at some point one should step back and fully think through one's objections. I think question guy's problem is that he didn't imagine the elevator outside of a gravitational field. Because he didn't do that when professor Susskind put the elevator back into a gravitational field question guy got confused. I think, I could be wrong though.

10:20 don't argue with someone that smart you stupid twat

[bbsonjohn]

the annoying guy must be mathematician!

[Seracinfinity]

Fantastic teacher!

@csmcmillion In Einstein Notation it is expressed as j, and is referred to as the Dummy Index.

How does no one in a class at Stanford know that dP=(dP/dx^n)dx^n is the total derivative....
