In another post I recommended to a fellow HBL’er the YouTube channel of Dr. Jorge Diaz.
I found him through random searches about how nuclear weapons work and some research in shockwave theory.
He has great videos going into quite a bit of detail with the history behind it all.
He recently started a series/course on quantum theory. It is still ongoing and he just reached the wave equation (no video out as yet)
I highly recommend him.
His channel: [Channel]
Quantum theory playlist: [Quantum]
Physics of Nuclear weapons: [Nuclear]
