I read up on that and it sounds as if you don't know calculus you're toast. I have no calculus whatsoever so it might be well over my head. What do you think?
Right now I'm re-reading Brian Greene's, "The Fabric of the Cosmos".
I just looked through it and I realized that you do need to know calculus. I didn't really notice for some reason, probably because it is very basic calculus. You should probably read an "Idiots Guide to Calculus" or some book like that, because that is all teh calculus you need for this book.
What you need to understand is that dx/dt equals the instantaneous rate of change of x with respect to time, which is velocity. The derivative of that is d'x/d't, which is the instantaneous rate of change of velocity, which is acceleration. That's about as deep as it goes.
