Nice videos, but I would skip the reviews in your place. The reviews are great for summarizing an hour and a half lecture for five minutes before the next one starts. Not so much so when you talk for 13 minutes, 5 of which are spent on repeating the last video - If I cant remember something - I can just go and rewatch the old ones ;)
I really love your lecture. but can you explain about Hartree approximation (Hartree product) that you said Mean-field approximation in lecture?? I want understand exactly that concept. thanks.
