This book provides a clear, honest explanation of the theory of quantum electrodynamics for a nontechnical audience, which is a subject that may be somewhat challenging. Its goal is to help the interested reader understand the method of reasoning that physicists have used to describe how Nature operates. It is a transcript of the quantum electrodynamics lectures Richard Feynman gave at UCLA. Nothing in this book needs to be "unlearned" if you plan to or are already studying physics because it provides a thorough and accurate presentation of a framework that more complex ideas may be added to without changing. It's a revelation of what you were capable of if you've already studied physics, for those of you
