Hello! When will you continue the mathematical foundations of quantum mechanics series? also thank you for all your videos they help me a lot! especially the tensors and manifold playlists right now
I think next lecture, if its not already planned, it would be worthwhile to mention 'residual' gauge invariance. I.e. even after choosing say, the Lorenz gauge, you can still of course shift by some function G such that □G=0. And you remain in a different Gauge which is still a Lorenz gauge
This is a bit harder than it sounds given the freestyle way I produce the material. However, the order the material lies in the playlist is the order of intended viewing.
7:54 - But... that's WRONG. A has direct physical effects in the world; Aharonov and Bohm demonstrated this in 1959. The potentials are real. So I guess you can "adopt" any position you want, but you should at least tell people that those fields have real demonstrable physical effects.
Great lecture as always!
Glad you think so!

Not sure yet. It wasn't very popular and the material is very difficult.
love the video! I was just wondering whether there is meant to be a 1/c^2 in front of the A double dot at 14:23? Thank you :)
Yep. That factor should be distributed with the time derivative.

Didn’t I mention that in this video? That is a good point.
@@XylyXylyX don't recall, could have been implied/mentioned and I missed it!
Great lecture...please add sutitles captions.. thank

What's the F?
😀
Some scalar function that you have the luxury to choose
Hi there, would you like to assign proper serial no. to your videos.
Yess, I second that request...
