Executive summary: High-pressure physics

American physicist Percy Williams Bridgman won the Nobel Prize for Physics in 1946, for his development of new techniques to pioneer high-pressure physics, and his studies of the effects of pressure on solid, liquid, and gaseous matter. He introduced the self-tightening joint in 1909, and using this and other equipment of his own design during his career he increased the maximum pressure scientists could exert from about 3,000 to 420,000 kilograms per square centimeter. In 1927 he presented a theory of operationalism, suggesting that concepts are simply sets of operations. In 1955, he served as consultant to General Electric as scientists at the company's labs used high-pressure technique to convert graphite into a synthetic diamond.

He was raised in the Congregational Church, but faith in God clashed with his well-known analytical nature and he told his family as a young man that he could not in good conscience become a church member. Of libertarian ideology, he began refusing to work with scientists from nations he deemed totalitarian several years before the United States was drawn into World War II. When his daughter became engaged in 1948 he became a temporary Justice of the Peace, for just long enough to conduct her non-religious marriage ceremony himself.

His students included nuclear physicist Robert Oppenheimer. His father-in-law, Edmund Asa Ware (1837-85), was the founder of Atlanta University. Bridgman developed bone cancer in his 70s, and ended his life with a .22-caliber sawed-off rifle at his home in Randolph, New Hampshire on 20 August 1961. In 1977, the International Association for the Advancement of High-Pressure Science and Technology established the Percy Williams Bridgman Award in his honor and memory.
