Hello Everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I didn't know whether to post this here or in the Physics area. Basically i'm trying to get a good understanding of Tensors so that I can apply them to General Relativity. I'm a freshman in college and kind of been teaching myself this advanced physics since i was 14, and now that i have multivariable calculus and some ODE knowledge under my belt i'm trying to expand my knowledge from a conceptual understanding to a mathematical one.

I really just dont get how tensors work/what they are/how to convert from cartesian coords to a tensor (if thats what you do). I have a textbook from the schools library on relativity but it just assumes one has a knowledge of Tensors. I kind of vaguely get what they are (via Wikipedia) but does anyone know a book/source that introduces the concept (from a physics standpoint, because i believe a Tensor in physics is actually a Tensor-Field in Mathematics).

Any help would be appreciated!

Thanks!

PS - If this should be in the physics forum i apologize!
