January 1928: Dirac equation unifies quantum mechanics and special relativity

For those enjoying the history of early quantum mechanics, I've been following Dr. Jorge S. Diaz on YouTube[1].

He has a great video series going on the people, experiments and discoveries that lead to quantum mechanics.

The videos are very accessible, but he does go into some details like various key derivations and such. Well worth watching for casual physics fans IMHO.

Diaz is awesome. For me, he manages to strike just the right balance between making the topic interesting in a historical/human-interest sense and including enough technical detail to cultivate actual insight. Both his Franck-Hertz and Stern-Gerlach videos are the best I've run across on YouTube (and I see the latter has a part 2 now, so that'll be next on my watchlist.)

Hugely underrated YouTuber.

I also just love his energy. He's unapologetically excited about the stuff that excites him, and even if I don't share all his interest, it makes his videos an absolute joy to watch.

Thank you. Just in time for the weekend!
