haha First Video 330,000 views, second 177,000 third 77,000 its going down and down...pity cause they are great videos

k = 1/length = ħ^(-1/2) G^(-1/2) c^(3/2)

2pi=Tau

Can someone explain how at 13:00 the basis vectors m and n become summation indices. I understand both notations (I think) but I just don't understand how he derived Knm from (nI K Im)

What does it mean to be orthogonal in complex space?

@TheChadSitze Check out a book from the library?
-
ahhhhh i see. Thank you for explaining!

@Evan2718281828 are things like gaussians or plane waves. For your linear wavefunction, it's not normalizable, hence the need to invent a weird system. For a wavefunction to make physical sense, we usually require that it decays to zero as x goes to infinity and minus infinity. There's also other technicalities... you'd probably be better off learning this stuff from a book. The David Griffiths book is the one I use, and it's excellent. Also I hadn't noticed the e in your name =P nice



FINALLY! A way to learn in depth QM material while in the nude!

Free lectures on the internet is the best that happened to me in a long time. Thank you Stanford, MIT, Oxford and all the others! Really appreciate it!!
