I have checked out a bunch of general chemistry textbooks. Four are really excellent. General Chemistry: Principles and Structure by James E. Brady and Gerard E. Humiston (this book's coverage of physical and chemical equilibrium is excellent) Chemistry: The Molecular Nature of Matter and...

thanks guys!

Thanks. How exactly did you go do this step? Now divide both sides by c\Delta t and you get: \frac{s}{c\Delta t}=\sqrt{\frac{-(\Delta x)^2}{c^2(\Delta t)^2}+1} I get everything after that.

hey thanks! I really need to brush up on my math!

could someone help me out with this or give me some tips on what to study to be able to figure this out?

This has been driving me insane. I don't get how he went from s/c to t/y. If someone could explain step by step how you do it I would greatly appreciate it.
