Although the content was at a lower level than I was hoping for, this book did provide a relaxing and educational overview of quantum electrodynamics. It explains how light reflects based on quantum wavefunctions and how this causes irridescence. It spends a lot of time explaining the concept that the paths of particles are actually determined by taking all paths simultaneously and then the quantum wavefunctions are added to find that most paths have destructive interference of wavefunctions which leaves only the classical path. Many Feynman diagrams are used to illustrate the possible interactions of photons and electrons. The information density in this book is pretty low, but that is not such a bad thing. The information it does contain is pretty interesting and by telling it slowly, it is easier to understand.
