Abstract: This article recommends a fascinating book by the Nobel Prize winner Richard Feynman, in which he explains the quantum nature of light - in fact, quantum electrodynamics - in a fascinating way.

Normally, it should be considered a hopeless attempt to explain the basics of quantum electrodynamics (QED) to lay persons. The Nobel Prize winner Richard Feynman once took this challenge and mastered it in a way which is amazing indeed. It may be irritating at first how Feynman takes this deductive approach, first describing a photon model for light which has to appear rather strange to the beginner. Then, however, he demonstrates in a fascinating way how a variety of surprising phenomena can be deducted from that model. Of course, anyone dealing more closely with photonics, e.g. studying it at University level, will also have a lot of pleasure from reading this book, which demonstrates very nicely how fascinating physics can be.
