Einstein's General Theory of Relativity | Lecture 6

Lecture 6 of Leonard Susskind's Modern Physics concentrating on General Relativity. Recorded October 27, 2008 at Stanford University.

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.

whats up with the dude asking stupid questions?

[Aure217]

Would just like to point out that when the lecturer doesn't have immediate answers to questions, it's because the questions aren't phrased in a way that makes sense.

(Like...the questions aren't "Is the sheep actually a cow?", they're "Will the bricks be sleeping quickly yesterday?")

A standard ring torus in 3-dimensional space has curvature... so it cannot be represented by a non-stretching piece of paper.

@buttegowda

theta is the deficit angle, so it is very small when the cone is amlost flat

@gikiian hahahahahahaha... oh that's a good one

[HKMFilms]

Hair cut!

I do not how to thank prof Susskind. Great series. makes Physics very eassy to understand and math behind it very logical.

One dumb question: Ref to 1:25:00 on words,

The equation of dTheta = R.dArea, is an approximation and is valid only when Theta is very small ( when sinTheta can be treated as Theta ) ... How will it be valid at the tip, where dTheta tends to 180 degrees ??

Return of annoying guy!

@gopaw1 i can find a metric to turn german into latin, though
