Paul Dirac, like Richard Feynman, is one of the main representatives of the “second generation” of scientists who turned to quantum mechanics after the pioneering work of Planck and Einstein. The famous equation, named after Dirac, which describes in detail the behavior of certain particles, including the electron, united the theory of relativity and quantum theory for the first time. The Dirac equation proved the possibility of the existence of “antipodes” of particles known at that time - the electron, proton and others. The newly discovered particles are known to us as antimatter. Silent and reserved, modest and completely passionate about his work, this English engineer became a scientist who developed one of the most advanced theories of modern physics.
