Did you know that Albert Einstein won the Nobel Prize for the theory of relativity?
Or that was rejected at the Polytechnic entrance exam? All this you can read in the book but especially you can see the reasoning that led the great Albert to guess and then develop the theory of relativity. Considered by many people difficult and mysterious, perhaps it will become easier and more fun for you because you'll find yourself to follow Einstein's reasonings and his results will become yours too.
