Electrodinámica cuántica

Quantum electrodynamics is one of the most accurate, but also the most complicated, physical theories. In this book, Richard P. Feynman (1918-1988) presents that theory with the clarity, precision, and thoroughness that made him famous. Assuming little scientific knowledge in the readers and delving into the intuitive and visual content of the theory, Feynman describes the interaction between light and electrons, "absurd" from the point of view of common sense but that is at the base of practically everything that we observe in the physical world. The pages of "Quantum Electrodynamics" satisfactorily explain phenomena as familiar as light reflecting off a mirror or curving as it passes from air to water. Two aspects of this book will be especially appreciated by all those interested in modern physics: on the one hand, the way in which Feynman introduces his famous "diagrams", an absolutely fundamental tool for the study and application of this theory, and on the other hand , his use of "possible paths", with which he built his well-known interpretation of quantum mechanics.
