Richard C. Tolman
Richard Chace Tolman was a pivotal American mathematical physicist and physical chemist whose work bridged the gap between quantum mechanics, thermodynamics, and cosmology. A Caltech professor and leading wartime advisor, Tolman significantly advanced relativistic mechanics, formulated groundbreaking cosmological models, and established electricity's electron-based nature. Tolman was born in West Newton, Massachusetts, on March 4, 1881, Tolman pursued a rigorous education at the Massachusetts Institute of Technology (MIT), earning his bachelor’s degree in chemical engineering in 1903 and a PhD in 1910 under the guidance of Arthur Amos Noyes. Following his studies, he held positions at the University of Michigan, the University of Cincinnati, and the University of Illinois. In 1912, he introduced the concept of relativistic mass. In 1916, he and T.D. Stewart proved that electrical current in metals consists of flowing electrons, measuring the mass of the electron...
