Studying general relativity, since it's the flagship application of my field of mathematics (differential geometry) and yet I only know the basics. It is, of course, the most elegant scientific theory of all time.
I’ve been wanting to ask this a differential geometer - what do you think of Sussman and Wisdom’s book as a DE intro for an CS/applied math person? Thanks!
Never read it, but the preview pages look pretty neat. I might pick it up for a fun read. Might want to pair it with something like do Carmo's Differential Geometry of Curves and Surfaces (which is quite accessible) for the mathematical side.
