This is the book I used to learn Einstein's Theory of Relativity. It's back to my favourite cartoon book series. I used to own a copy but lent it to a girl called Rebecca in 1993. I never saw it again. But what stuck with me was the way in which Einstein did thought experiments to figure out what was going on. I still teach about the way in which Einstein went about answering this question: if I am travelling at the speed of light, can I still see my reflection in a mirror that I am holding in front of my face? This is the book that sorted it all out for me. You should read it too!
