During WW II, he developed a radio proximity fuse and later was a health-physics scientist with "Manhattan Project." Hoffman studied nine accident victims of radiation disease at Los Alamos in Aug 1945 and May 1946. This research revealed for the first time that atoms of living human tissue could be transformed into radioactive atoms. He recognized "a completely new approach to studying the metabolism of atoms in living tissue and a new way of probing the complicated system of gene cells that determine heredity," and such knowledge was indispensable to understanding the mysteries of cancer research in which he engaged for the rest of his life.

Agramonte had acquired immunity to yellow fever from a mild childhood case in Cuba before emigrating to the U.S., which was an advantage when he was chosen by the Surgeon-General to study the yellow fever outbreak in General Shafter's army in Cuba. There Agramonte performed autopsies in order to determine the causative agent of the disease.

U.S. Army Air Corps pilots flying B-29 bombing missions across the Pacific Ocean during World War II proved the jet stream's existence. The pilots found that when they flew from east to west, they experienced slower arrival times and fuel shortage problems. When flying from west to east, however, they found the opposite to be true. Rossby created mathematical models (Rossby equations) for computerized weather prediction (1950).

||1960, the first commercial atomic energy reactor, and the third in the U.S., achieved a self-sustaining nuclear reaction. It began producing power for distribution on 10 Nov 1960. This was the $57 million Yankee Atomic Electric Company's plant at Rowe, Mass., on the Deerfield River. The pressurized light-water reactor produced 125,000 kilowatts of electricity. The company was formed by twelve New England utility companies which signed a contract with the Westinghouse Corporation as the principal contractor. It was permanently shut down on 26 Feb 1992, due to reactor vessel embrittlement, after more than 31 years of service. Decommissioning began in 1993. | ||1960, the first commercial atomic energy reactor, and the third in the U.S., achieved a self-sustaining nuclear reaction.
