Bridgman was born in Cambridge, Massachusetts . He entered Harvard University in 1900, studying Physics , and from 1910 he began teaching at Harvard, finally as a professor from 1919 . He had, in 1905, begun undertaking research regarding certain phenomena under the influence of pressure. Due to a machinery malfunction, he modified his pressure apparatus, and the result was that he had invented a new piece of machinery that would enable him to create pressures up to and above 100,000 Kgf / Cm&2 (10 GPa ). This is a huge improvement on previous machinery in which pressures of only 3000 kgf/cm&2 (0.3 GPa) could be attained. He developed the Bridgman Seal and is the eponym for Bridgman's Thermodynamic Equations . With this new apparatus a plethora of new research was investigated, including research into the effect of pressure on electrical resistance, and solid and fluid conditions under pressure. Bridgman is known also for his studies of electrical conduction in metals and properties of crystals and for his writings on the philosophy of modern science. He was also one of the 11 signatories to the Russell-Einstein Manifesto . MAJOR WORKS
