I'm a beginner, thinking about returning to school for physics, but I'm dipping in with this tome I purchased recently. He's a great explainer for someone at my level.

And I have to brush up on all of the math (and learn calculus...) in order to fully understand. It's exciting that reading him isn't just a cold hard wall. It's proving to be a great guide into what to sort of triage my studies.

I strongly second this one! (Though I have to admit that I purchased a not-cheap edition of the first volume to get started -- though I prefer reading from paper, and don't yet own an eReader and have a bit of a burgeoning library anyway. But thanks for the link! it's nice to have the rest on hand).
