Any textbook recommendations for tensor calc? I've already taken lin alg and algebra without much trouble, but no real analysis yet. I hear this book is good. What do you think anons?

>function that takes two vectors
Vectors aren't tensors and vice versa. Vectors are generators of parallel transport, or directional derivatives.

Since the dual of a covector can be thought of as a vector, then a vector is essentially just a (0,1) tensor.

He's technically not wrong, since a (0,1) tensor is a map that takes a covector to scalar, whereas a vector is an element of a vector space, but it's so overly pedantic.

Seconded in theory, but if you don't know shit about topology, straight manifolds will be rougher going.

Relax buddy, your post explained the idea of tensors to a high school student. You didn't really describe them at all.

Yes.
I don't post much outside of /sqt/, so you might be thinking of someone else.
