George E. Valley Jr.
George Edward Valley Jr. (September 5, 1913 – October 16, 1999) was an American physicist who joined the MIT Radiation Laboratory in 1940, where he led the development of the H2X radar bombsight. After the war he became a professor of physics at MIT. He helped found the MIT Lincoln Laboratory, invented the SAGE air defense system, and started the MIT Experimental Studies Group. Valley went to Flushing NY public schools and then to the Massachusetts Institute of Technology where he graduated with an SB in physics in 1935. His Bachelor's thesis was "Development of White Standards for Use in Colorimetry" with Prof. Arthur C. Hardy. After working for Bausch and Lomb Optical Co. for a short period of time, he enrolled as a graduate student in physics at the University of Rochester where he obtained his PhD under Prof. Lee A. DuBridge in 1939; his thesis, titled “The Determination of the Energies of the Radiations from Artificial Radioactive Elements”, involved development and ap ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
H2X Radar Bombsight
H, or h, is the eighth letter of the Latin alphabet, used in the modern English alphabet, including the alphabets of other western European languages and others worldwide. Its name in English is ''aitch'' (pronounced , plural ''aitches''), or regionally ''haitch'' (pronounced , plural ''haitches'')''.''"H" ''Oxford English Dictionary,'' 2nd edition (1989); ''Merriam-Webster's Third New International Dictionary of the English Language, Unabridged'' (1993); "aitch" or "haitch", op. cit. Name English For most English speakers, the name for the letter is pronounced as and spelled "aitch" or occasionally "eitch". The pronunciation and the associated spelling "haitch" are often considered to be h-adding and are considered non-standard in England. It is, however, a feature of Hiberno-English, and occurs sporadically in various other dialects. The perceived name of the letter affects the choice of indefinite article before initialisms beginning with H: for example "an H-bomb" ...

Condon Report
The Condon Committee was the informal name of the University of Colorado UFO Project, a group funded by the United States Air Force from 1966 to 1968 at the University of Colorado to study unidentified flying objects under the direction of physicist Edward Condon. The result of its work, formally titled Scientific Study of Unidentified Flying Objects, and known as the Condon Report, appeared in 1968. After examining hundreds of UFO files from the Air Force's Project Blue Book and from the civilian UFO groups National Investigations Committee On Aerial Phenomena (NICAP) and Aerial Phenomena Research Organization (APRO), and investigating sightings reported during the life of the Project, the Committee produced a ''Final Report'' that said the study of UFOs was unlikely to yield major scientific discoveries. The Report's conclusions received a mixed reception from scientists and academic journals. The report has been cited as a decisive factor in the generally low level of intere ...

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. It publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. It is a member society of the American Institute of Physics. Since January 2021, it is led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the APS was to hold scientific m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
