Query: Theoretical physics explained to the non-scientist

I read this book 25 years ago, yet it remains the single clearest explanation of Einstein's theories, particularly the theory of relativity, that I have ever read. Of particular note, the explanations usually employ the same mental pictures that were used by Einstein to develop the theories, e.g., an elevator moving through space, with no reference points. This is a particularly appropriate book to give to a high school student who has an interest in science but who may not yet have progressed through the basics of physics. I read it at that age, and it sparked an interest in physics, particularly light theory, that exists to this day
