The debate opens: Can you call yourself a Physicist if you do not know quantum mechanics? (Or Maxwell equations. Or thermodynamics) No. The debate closes.https://twitter.com/Liv_Lanes/status/1183882614245081088 …

The more interesting debate is whether all physicists should know general relativity and the Standard Model. I think we all should! But they're not taught as well as they could be, and they're not part of the standard curriculum yet.

I admit I am really sad for the poor state of my knowledge of GR. But at least I have seen Christoffel symbols and metric tensors during my undergrad.

General relativity is lots of fun! People tend not to say what Einstein's equations for GR actually *mean*, so I explained it here: http://math.ucr.edu/home/baez/einstein/ …

I still think it's best to view the geometry of spacetime as a thing of (elegantly compatible) parts, just as Hilbert viewed Euclidean geometry. This was Weyl's preferred perspective, and its elaboration by Ehlers-Pirani-Schild (and, ultimately, by NMJ Woodhouse) is irresistible.
