QED by Richard Phillips Feynman — Open Library

QED

Science and nature

First published: 1985
Print length: 158 pagesPrinceton University Press, 2007

Description

Richard Feynman asks how light and matter behave at their smallest scales, then builds an answer for readers without specialist training. Adapted from four public lectures, QED introduces photons, electrons, reflection, and other quantum phenomena through wit, carefully chosen mathematics, and visual intuition. Feynman’s clocklike arrows represent complex numbers and show how alternative paths combine into observable probabilities, allowing readers to follow calculations without the machinery of a conventional physics textbook. He is less interested in teaching efficient professional technique than in making the theory’s strange logic graspable. The book offers a compact encounter with quantum electrodynamics as both a predictive method and a challenge to everyday ideas about how nature works.

About Richard Phillips Feynman

Richard Feynman was an American theoretical physicist whose books grew largely from lectures, recorded conversations, interviews, and public investigations. His subjects range from quantum electrodynamics and the behavior of subatomic particles to scientific education, institutional failure, and the practical habits of curiosity. He explains by rebuilding a problem from elementary questions, shifting perspective, and testing an idea against a concrete example. The Feynman Lectures on Physics preserves this classroom method on a broad scale, favoring physical intuition and connections between problems over formulas presented as settled rules. In QED, he uses visual devices such as clocklike arrows to lead nonspecialists through the probabilities governing light and matter. His memoirs use a looser, episodic structure. Surely You’re Joking, Mr. Feynman! assembles experiments, pranks, arguments, and intellectual detours into a self-portrait, while What Do You Care What Other People Think? moves between intimate recollection and the Challenger inquiry. In both scientific and autobiographical writing, his recurring method is to distrust received language, isolate the underlying question, and follow the evidence.
