Leopold Infeld – författare

Leopold Infeld was one of the nine eminent scientists who, together with Albert Einstein, signed Bertrand Russell's famous letter warning that in this nuclear age, only a ban on war itself could save this planet (July, 1955). Infeld was born in the Jewish ghetto of Cracow, Poland in 1898, and this autobiography contains a vivid description of this long-since-vanished world. He was assistant to and then a scientific collaborator with Albert Einstein at the Institute for Advanced Study, Princeton, NJ (1936-1938), and this collaboration continued for twelve years while Infeld was at the University of Toronto. In 1938 he wrote a book together with Albert Einstein that became a number one bestseller, The Evolution of Physics. Infeld was lecturer and then Professor of Applied Mathematics at the University of Toronto from 1938--1950. From 1945-1950 he gave many lectures all over Canada on the elementary physics of the atom bomb, warning that Russia would soon have the bomb and urging that the short period of U.S. monopoly be used constructively, for peace. In 1950 he left Canada to become Professor of Theoretical Physics at the University of Warsaw as well as the founding director of the Institute of Theoretical Physics at that university, where he remained until 1967, the year before he died.

Motion and Relativity focuses on the methodologies, solutions, and approaches involved in the study of motion and relativity, including the general relativity theory, gravitation, and approximation. The publication first offers information on notation and gravitational interaction and the general theory of motion. Discussions focus on the notation of the general relativity theory, field values on the world-lines, general statement of the physical problem, Newton''s theory of gravitation, and forms for the equation of motion of the second kind. The text then takes a look at the approximation method and the equations of motion and motion and the Newtonian and post-Newtonian approximation. Topics include general remarks on the approximation method, two forms of the equations of motion and integrability conditions, approximation method and coordinate system, and development of the metric field. The manuscript examines the variational principle and the equations of motion of the third kind and the one and two particle problems. The formulation of the problem, Lagrangian up the sixth order, motion of a test particle in the field of a heavy particle, two-body problem, and motion of rotating bodies are discussed. The text is a dependable reference for readers interested in the methodologies, solutions, and approaches involved in the study of motion and relativity.
