Lecture 3 | Quantum Entanglements, Part 1 (Stanford)

Lecture 3 of Leonard Susskind's course concentrating on Quantum Entanglements (Part 1, Fall 2006). Recorded October 9, 2006 at Stanford University.

This Stanford Continuing Studies course is the first of a three-quarter sequence of classes exploring the "quantum entanglements" in modern theoretical physics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

Suprisingly, he makes a real mess of the orthogonality proof at 1:04:50.

When he reverses 'a' and 'b' in the second equation, he's already conjugated, so he should have: (blMla)=B*(bla)

and not

(blMla)*=B*(bla)*,

 the B here standing for the eigenvalue, I can't type lamda.

Then all he needs to do is show that B*=B as B is real.

I hope this helps for anyone as confused as I was!

What an incredible find. There is no way in the world to match the quality or value of the material being presented here - if you actually want to be conversant in quantum mechanics without spending your life. Given all that, does anyonw know which of these lectures actually gets into a discussion, definition, manipulation of entangled particles?

@4kx I wish I knew what could (reliably) make people happy. But, yes, I think this is a better question than "what job is waiting for me?".

[4kx]

@alecbrady since I was a kid, I loved know how things works, how machines, electronics, toys works - very often I crashed them to see what is inside. The universe is the most complicated toy we can imagine, understanding how IT works probably is the most beautiful thing in it. However, does physicist are happy? Dealing with numbers, models make them happy trough whole live?

[alecbrady]

@4kx I can't tell you what job would be waiting for you; but I can tell you that - if that's the question you want to ask - you should stick with engineering. If you're going to change, do it because you love the subject, not because you can sell yourself at a higher price.

[4kx]

Could me some one tell me, what job is waiting for me, if I change my studies to theoretical physic? I'm now on mechanical engineering, is it worth to change the studies?

As a student who is first exposed to quantum mechanics, without a doubt this is an excellent series of lectures.

I bought books on this topic but this is much better as an introduction. It's a help to understand the Schrodinger wave viewpoint before this imo as they are all related.

complex and modified. hard to absorb.
