Frank Erhart Emmanuel Germann through eight editions between 1938 and 1985. His most influential textbook was "College Chemistry" (Englewood Cliffs, New Jersey: Prentice-Hall, 1952, 1958, 1965). A popular trimmed version was "Essentials of College Chemistry" (Prentice-Hall, 1960). Charles Franklin Metz, another Germann graduate student (M.S. 1928, Ph.D. 1936), was one of the twelve scientists who conducted the world’s first firing of a nuclear weapon, the “Trinity” test on New Mexico’s Alamogordo Bombing and Gunnery Range on Monday, July 16, 1945. On Monday, August 6, 1945, a nuclear bomb was detonated over Hiroshima, Japan. Later that week, on Thursday, August 9, 1945, a nuclear bomb
B46 nuclear bomb was redesignated the B53 nuclear bomb and W53 warhead. 50 B53 bombs were in US inactive reserves from 1997 to 2011, though none were actively deployed during that period. B46 nuclear bomb The B46 nuclear bomb (or Mk-46) was an American high-yield thermonuclear bomb which was designed and tested in the late 1950s. It was never deployed. Though originally intended to be a production design, the B46 ended up being only an intermediate prototype which was test fired several times. These prototypes were known as TX-46 units (Test/Experimental). The B46 design roughly weighed 8,120 pounds and was about 37 inches
