Hello, I'd like to learn about tensors so i can start learning about special relativity. I understand nothing right now about tensors, except that they mean different things to mathematicians and to physicists, which is where my confusion begins! Should i learn about the modern way of doing tensors without coordinates, or should i learn the 'classic method'. I'm very confused. Anyone know any good websites with basic lectures or notes on tensors? Also, does any1 happen to have msn so i might be able to ask a few questions in real time as they prop up? Thank you.
