4 Pierce, John Robinson
[br]b. 27 March 1910 Des Moines, Iowa, USA[br]American scientist and communications engineer said to be the "father" of communication satellites.[br]From his high-school days, Pierce showed an interest in science and in science fiction, writing under the pseudonym of J.J.Coupling. After gaining Bachelor's, Master's and PhD degrees at the California Institute of Technology (CalTech) in Pasadena in 1933, 1934 and 1936, respectively, Pierce joined the Bell Telephone Laboratories in New York City in 1936. There he worked on improvements to the travelling-wave tube, in which the passage of a beam of electrons through a helical transmission line at around 7 per cent of the speed of light was made to provide amplification at 860 MHz. He also devised a new form of electrostatically focused electron-multiplier which formed the basis of a sensitive detector of radiation. However, his main contribution to electronics at this time was the invention of the Pierce electron gun—a method of producing a high-density electron beam. In the Second World War he worked with McNally and Shepherd on the development of a low-voltage reflex klystron oscillator that was applied to military radar equipment.In 1952 he became Director of Electronic Research at the Bell Laboratories' establishment, Murray Hill, New Jersey. Within two years he had begun work on the possibility of round-the-world relay of signals by means of communication satellites, an idea anticipated in his early science-fiction writings (and by Arthur C. Clarke in 1945), and in 1955 he published a paper in which he examined various possibilities for communications satellites, including passive and active satellites in synchronous and non-synchronous orbits. In 1960 he used the National Aeronautics and Space Administration 30 m (98 1/2 ft) diameter, aluminium-coated Echo 1 balloon satellite to reflect telephone signals back to earth. The success of this led to the launching in 1962 of the first active relay satellite (Telstar), which weighed 170 lb (77 kg) and contained solar-powered rechargeable batteries, 1,000 transistors and a travelling-wave tube capable of amplifying the signal 10,000 times. With a maximum orbital height of 3,500 miles (5,600 km), this enabled a variety of signals, including full bandwidth television, to be relayed from the USA to large receiving dishes in Europe.From 1971 until his "retirement" in 1979, Pierce was Professor of Electrical Engineering at CalTech, after which he became Chief Technologist at the Jet Propulsion Laboratories, also in Pasadena, and Emeritus Professor of Engineering at Stanford University.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Morris N.Liebmann Memorial Award 1947; Edison Medal 1963; Medal of Honour 1975.

10 loi de Moore
La loi de Moore concerne les puces électroniques. Cofondateur et P-DG d’Intel de 1975 à 1987, Gordon Moore observe que le nombre de circuits intégrés présents sur une puce double tous tous les ans. En avril 1965, dans un article de la revue Electronics Magazine sur l’avenir des composants de semi-conducteurs, Gordon Moore effectue cette extrapolation basée sur une observation empirique. En 1975, il l’actualise en portant la durée à deux ans. Cette extrapolation est ensuite baptisée loi de Moore par l’un de ses amis, Carver Mead, professeur à Caltech (California Institute of Technology). Devenue célèbre, la loi de Moore s’étend ensuite à toute l’industrie informatique, pour mesurer sa croissance rapide, et devient par là-même le catalyseur de cette croissance. -
11 UBL
(Ultimate Band List)Débuté pendant l’été 1994 à Caltech (California Institute of Technology) et connu d’abord sous le nom de WWWOM (Web Wide World of Music), UBL (Ultimate Band List) devient un vaste et très populaire répertoire de liens musicaux. Après une interruption, le sigle bien connu donne son nom à un UBL nouvelle formule géré par la société ARTISTdirect.Voir aussi: musique en ligne, répertoire, web.
