American physicist Richard Feynman is one of the creators of quantum electrodynamics. A Nobel laureate, but above all, an extraordinary multifaceted personality who does not fit into the usual framework of the image of a “man of science.” He was known for his passion for jokes and pranks, painted amazing portraits, and played exotic musical instruments. An excellent speaker, he turned each of his lectures into an exciting intellectual game. Not only students and colleagues, but also people simply passionate about physics were eager to attend his speeches. He described his credo as a popularizer of science with one brilliant phrase: “If you are a scientist, a quantum physicist, and cannot explain in a nutshell to a five-year-old child what you do, - you are a charlatan.” Translation from English by Sergei Ilyin.
