Lawrence H. Johnston
Lawrence Harding Johnston (February 11, 1918 – December 4, 2011) was an American physicist, a young contributor to the Manhattan Project. He was the only man to witness all three atomic explosions in 1945: the Trinity nuclear test in New Mexico and the atomic bombings of Hiroshima and Nagasaki in Japan. During World War II, Johnston worked at the MIT Radiation Laboratory where he invented ground-controlled approach radar. In 1944, he went to the Manhattan Project's Los Alamos Laboratory, where he co-invented the exploding-bridgewire detonator. After the war, Johnston completed his Doctor of Philosophy, Ph.D. thesis in 1950, and became an associate professor at the University of Minnesota in Minneapolis.

MIT Radiation Laboratory
The Radiation Laboratory, commonly called the Rad Lab, was a microwave and radar research laboratory located at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. It was first created in October 1940 and operated until 31 December 1945 when its functions were dispersed to industry, other departments within MIT, and in 1951, the newly formed MIT Lincoln Laboratory. The use of microwaves for various radio and radar uses was highly desired before the war, but existing microwave devices like the klystron were far too low powered to be useful. Alfred Lee Loomis, a millionaire and physicist who headed his own private laboratory, organized the Microwave Committee to consider these devices and look for improvements. In early 1940, Winston Churchill organized what became the Tizard Mission to introduce U.S. researchers to several new technologies the UK had been developing. Among these was the cavity magnetron, a leap forward in the creation of microwaves that made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Associate Degree
An associate degree is an undergraduate degree awarded after a course of post-secondary study lasting two to three years. It is a level of qualification above a high school diploma, GED, or matriculation, and below a bachelor's degree.
