thank you! this video helped a lot with my finals studying. we use the MIT textbook so im glad there are well-done lectures that go over the material :)

Please don't edit out the discussions between the professor and the students. That's a part of learning !

very good content sir. thank you .. sir kindly make a video on Bound

States for Potential Wells with no rigid walls.

[jeetsharma]

Thank you so much for this informative and understandable video

[miffyn]

Very satisfying explanation, thanks sir

[Sk-bpji]

Thanks MIT and thank sir your video is very helpful

is N^2 is the maximum value of probability in the graph?

[thomaslupo]

What about the derivative of the outer and inner functions at the boundary. The derivative of sin is not 0. Should inner function be 1-cos(2*pi/a*x)

[AT-zfxf]

It is not clear why n=1, 2, 3, ... here. He argues that for the circle also n<0 is allowed because the momentum changes sign. Should not a similar thing happen here (namely n belongs to Z except 0), with negative n values giving a negative momentum, thus a different eigenstate?

[saikatmaji]

If a is rational, lets say a = p/q, then for n multiple p the eigenstate vanishes. Hence we cant take a rational here.

Holy, effin, shite. Why was this so much easier to compartmentalize? The 1/2 of the integral of sin was something wizard that makes way too much sense when pointed out like this.

Oh MIT why you can't record audio correctly?

Should some 16 year old sound engineers tell your professors how to do it? :)
