You are awesome dude. Fantastic videos. I don't personally use griffiths, but your clear and concise explanations help me take away a lot of information that is applicable to many problems. Thanks so much for the video.
How do you know that the ground state of hydrogen is symmetrical all over space and not for any other excited states? How can we know that? which equation tells us that i cant find it anywhere :(((
When you look at the wavefunction for the ground state, there are no theta or phi there. Hence, it doesn't change if you rotate space in a spherically simmetrix way (change any angle for another without moving x, y or z). Hope it helps!
Hi! The expectation value of r is the average distance in which you would find your particle if you performed your experiment many times. 1/r doesn't have an intuitive significance that I know of, but it is useful because we often use it when calculating other things

I have a problem to understand problem 1.13 (Buffon's needle). Will you please upload a solution of it??
Thank you
which book is that in? Maybe i'll check it out

sir pls give significance for expectation value of r and 1/r for hydrogen atom
