I'm currently self-studying complex analysis (CA), and reading "Visual Complex Analysis" by Tristan Needham. I'm absolutely fascinated by how much geometric intuition he provides for the key findings in CA. It has been a very enticing read so far.
I have a mechanical engineering background, I've previously self-studied general/algebraic topology, and I'm interested in self-studying differential geometry (DG) after finishing Needham's book. I know that Needham is in the process of releasing his next book, "Visual Differential Geometry". But the exact date of release is hard to find. Can anyone recommend a few good DG textbooks that (a) pay special attention to developing the geometric intuition of the reader (and perhaps less attention to rigorous mathematical proofs), and (b) would be appropriate for a reader with my aforementioned background?
Well, Spivak's (what was it $5$?) volume Comprehensive Introduction to Differential Geometry is in my opinion pretty good. And it seems to me he makes some effort to develop geometric intuition.
Sorry it's been so long that I can't remember specific examples ( I want to say he did $\Bbb RP^2$ pretty well).
I just remember calling Book Scientific, to order some books, and wouldn't you know it, Spivak answered the phone.
The covers of the volumes, incidentally, fit together into one big picture.
I dare say they're a must. And when I arrived at UCLA from Berkeley, what did I see on my advisor's shelf, but Spivak's epic.
