I've been told that Roger Penrose's The Road to Reality is awesome if you already know enough math. If you're an engineer, for example, you shouldn't have problems. Unfortunately, my personal level of mathematical maturity is too low and I've never made it past the first ten chapters. Maybe some day with more effort. :/

Second that. It's an awesome book that explains pretty much everything when it comes to physics. As for the math, it's true that they're hard but you should really give it another try since the second part of the book has less equations and more text.

I've heard good things about that one. I should get it. It came much later than the 1980s, of course.
