Remembering founding fathers: Leopold Infeld

News, 20 August 2021

On 20 August, the 123rd anniversary of the birth of a famous physicist of the XX century and one of the JINR founding fathers Leopold Infeld is celebrated. He was an academician of the Polish Academy of Sciences and some foreign academies, creator of the school of theoretical physics in Poland. He seemed to have made his own phrase as his motto “Nothing in the world should remain hidden from humanity”.

Working in Poland, Great Britain, the USA, and then again in his homeland, he wrote more than a hundred scientific papers on theoretical physics, including on the general relativity theory, the classical, relativistic, and quantum field theory, the interpretation of the uncertainty relations, the electron wave equation in general relativity theory (jointly with a Dutch mathematician B. L. van der Waerden, 1953). Jointly with M. Born, he developed a phenomenological model of classical electrodynamics (Born-Infeld theory, 1934 – 1935). In 1938, Together with A. Einstein and B. Hoffmann, within the general theory of relativity, he derived equations of motion for bodies from the field equations and constructed a working theory of gravitating bodies in a gravitational field.

He also wrote several fiction stories, including about Évariste Galois, the founder of modern higher algebra.

Moreover, Leopold Infeld was a member of the JINR Scientific Council.
