Feynman gave me some more tools than I previously had for understanding quantum mechanics. While I knew that electrons bumped around energy levels emitting and absorbing photons, I never really understood why that is significant or what phenomena it produces. What Feynman does is use common examples based on light to give meaning to the quantum behavior---give the why, when before all we could say is "defraction".
Though I will have to refer to this book again to understand these principles in further detail, Feynman did a great job presenting a rather difficult topic. I was confused at some points when he referred to a mathematical principle I am familiar with, such as referring to vectors as "arrows", or when I was trying to understand his description based on the quantum mechanics I already understand. I now, though, really want to read the physics book he wrote so I can better understand everything else I already think I know.
