On: How to Become a Good Theoretical Physicist

[santaclaus]

I'm surprised to see no explicit mention of differential geometry.

[ajkjk → santaclaus]

Agreed. But there are many implicit mentions. Lots of physicists pick it up on the side in other subjects, which probably isn't ideal.

Probably the book by Nakahara is most people's first stop.

[mhartl → santaclaus]

Differential geometry starts getting important once you hit General Relativity, and any good GR text will cover it thoroughly.
