E. H. Putley
Ernest Henry Putley (1922 – 29 November 2009) was a British scientist and prolific author. He is best known for his work on radar, the Hall Effect, and infra-red spectroscopy. Putley was born in South London and graduated with a BSc in physics from Queen Mary College in 1942. In August 1942 he started work at the Telecommunications Research Establishment The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) d ... (TRE) in Malvern, which was later known as RSRE, DERA, and more recently Dstl & QinetiQ. After the war he returned briefly to Queen Mary College to complete his PhD. Putley retired from RSRE in 1982 but returned almost immediately as an unpaid volunteer to record the history of the military electronic developments with which he had been involved for so long.

Hall Effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. A Hall effect can also occur across a void or hole in a semiconductor or metal plate, when current is injected via contacts that lie on the boundary or edge of the void or hole, and the charge flows outside the void or hole, in the metal or semiconductor. This Hall effect becomes observable in a perpendicular applied magnetic field across voltage contacts that lie on the boundary of the void on either side of a line connecting the current contacts. It exhibits apparent sign reversal in comparison to the standard "ordinary Hall effect" in the simply connected specimen, and depends only on the current injected from within the void. Superposition may also be realized in the Hall effect: first imagine the standard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Percival Rowe
Albert Percival Rowe, CBE (23 March 1898 – 25 May 1976), often known as Jimmy Rowe or A. P. Rowe, was a radar pioneer and university vice-chancellor. A British physicist and senior research administrator, he played a major role in the development of radar before and during World War II. Early years Rowe was born in Launceston, Cornwall, and after attending the Portsmouth Naval Dockyard School, he studied physics at the Royal College of Science, University of London, graduating with a first-class honours in 1921, and postgraduate diploma in air navigation in 1922. On 18 June 1932 at Beckenham, Kent, he married Mary Gordon Mathews, a solicitor. Air defence and radar In the Air Ministry he read up everything he could find on the art of air defence, and became alarmed. Working at that time for Harry Wimperis, he wrote a memo to him that concluded that "we were likely to lose the war if it starts within the next ten years". Wimperis took the report seriously, and in 1934 started th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Scientists
Science and technology in the United Kingdom has a long history, producing many important figures and developments in the field. Major theorists from the United Kingdom of Great Britain and Northern Ireland include Isaac Newton whose laws of motion and illumination of gravity have been seen as a keystone of modern science and Charles Darwin whose theory of evolution by natural selection was fundamental to the development of modern biology. Major scientific discoveries include hydrogen by Henry Cavendish, penicillin by Alexander Fleming, and the structure of DNA, by Francis Crick and others. Major engineering projects and applications pursued by people from the United Kingdom include the steam locomotive developed by Richard Trevithick and Andrew Vivian, the jet engine by Frank Whittle and the World Wide Web by Tim Berners-Lee. The United Kingdom continues to play a major role in the development of science and technology and major technological sectors include the aerospace, ...
