Engineering and technology notes

Walter Houser Brattain

Walter Houser Brattain (/ˈbrætən/; February 10, 1902 – October 13, 1987) was an American physicist at Bell Labs who, along with fellow scientists John Bardeen and William Shockley, invented the point-contact transistor in December 1947.[1] They shared the 1956 Nobel Prize in Physics for their invention. Brattain devoted much of his life to research on surface states.

Svalbard

Svalbard (Norwegian pronunciation: [ˈsvɑːlbɑː, ˈsvɑl-];[3] formerly known by its Dutch name Spitsbergen) is a Norwegianarchipelago in the Arctic Ocean. Situated north of mainland Europe, it is about midway between continental Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and Edgeøya.

J. Presper Eckert

John Adam Presper “Pres” Eckert, Jr. (April 9, 1919 – June 3, 1995) was an American electrical engineer and computer pioneer. With John Mauchly he designed the first general-purpose electronic digital computer (ENIAC), presented the first course in computing topics (the Moore School Lectures), founded the Eckert–Mauchly Computer Corporation, and designed the first commercial computer in the U.S., the UNIVAC, which incorporated Eckert’s invention of the mercury delay line memory.

Klaus Fuchs

Emil Julius Klaus Fuchs (29 December 1911 – 28 January 1988) was a German theoretical physicist and atomic spy who, in 1950, was convicted of supplying information from the American, British, and Canadian Manhattan Project to the Soviet Union during and shortly after the Second World War. While at the Los Alamos National Laboratory, Fuchs was responsible for many significant theoretical calculations relating to the first nuclear weapons, and later, early models of the hydrogen bomb.

Edward Teller

Edward Teller (HungarianTeller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-American theoretical physicist who was born in Hungary, and is known colloquially as “the father of the hydrogen bomb“, although he claimed he did not care for the title.[1] He made numerous contributions to nuclear and molecular physicsspectroscopy (in particular the Jahn–Teller and Renner–Teller effects), and surface physics. His extension of Enrico Fermi‘s theory of beta decay, in the form of Gamow–Teller transitions, provided an important stepping stone in its application, while the Jahn–Teller effect and the Brunauer–Emmett–Teller (BET) theory have retained their original formulation and are still mainstays in physics and chemistry.[2] Teller also made contributions to Thomas–Fermi theory, the precursor of density functional theory, a standard modern tool in the quantum mechanical treatment of complex molecules. In 1953, along with Nicholas Metropolis, Arianna Rosenbluth, Marshall Rosenbluth, and Augusta Teller, Teller co-authored a paper which is a standard starting point for the applications of the Monte Carlo method to statistical mechanics.[3]
