Richard Feynman is considered not only one of the most significant physicists of the 20th century, but also one of the most mesmerizing and unique figures of modern science. This scientist made a huge contribution to the study of quantum electrodynamics - the main field of physics that studies the interaction of radiation with matter, as well as the electromagnetic interactions of charged particles. In addition, he is widely known as a teacher and popularizer of science. Feynman's flamboyant personality and crushing judgments elicited both admiration and hostility, but one thing is certain: modern physics would not be what it is today without the input of this amazing man.
