27 Clarke, Arthur Charles
[br]b. 16 December 1917 Minehead, Somerset, England[br]English writer of science fiction who correctly predicted the use of geo-stationary earth satellites for worldwide communications.[br]Whilst still at Huish's Grammar School, Taunton, Clarke became interested in both space science and science fiction. Unable to afford a scientific education at the time (he later obtained a BSc at King's College, London), he pursued both interests in his spare time while working in the Government Exchequer and Audit Department between 1936 and 1941. He was a founder member of the British Interplanetary Society, subsequently serving as its Chairman in 1946–7 and 1950–3. From 1941 to 1945 he served in the Royal Air Force, becoming a technical officer in the first GCA (Ground Controlled Approach) radar unit. There he began to produce the first of many science-fiction stories. In 1949–50 he was an assistant editor of Science Abstracts at the Institution of Electrical Engineers.As a result of his two interests, he realized during the Second World War that an artificial earth satellite in an equatorial orbital with a radius of 35,000 km (22,000 miles) would appear to be stationary, and that three such geo-stationary, or synchronous, satellites could be used for worldwide broadcast or communications. He described these ideas in a paper published in Wireless World in 1945. Initially there was little response, but within a few years the idea was taken up by the US National Aeronautics and Space Administration and in 1965 the first synchronous satellite, Early Bird, was launched into orbit.In the 1950s he moved to Ceylon (now Sri Lanka) to pursue an interest in underwater exploration, but he continued to write science fiction, being known in particular for his contribution to the making of the classic Stanley Kubrick science-fiction film 2001: A Space Odyssey, based on his book of the same title.[br]Principal Honours and DistinctionsClarke received many honours for both his scientific and science-fiction writings. For his satellite communication ideas his awards include the Franklin Institute Gold Medal 1963 and Honorary Fellowship of the American Institute of Aeronautics and Astronautics 1976. For his science-fiction writing he received the UNESCO Kalinga Prize (1961) and many others. In 1979 he became Chancellor of Moratuwa University in Sri Lanka and in 1980 Vikran Scrabhai Professor at the Physical Research Laboratory of the University of Ahmedabad.Bibliography1945.

28 Heaviside, Oliver
[br]b. 18 May 1850 London, Englandd. 2 February 1925 Torquay, Devon, England[br]English physicist who correctly predicted the existence of the ionosphere and its ability to reflect radio waves.[br]Brought up in poor, almost Dickensian, circumstances, at the age of 13 years Heaviside, a nephew by marriage of Sir Charles Wheatstone, went to Camden House Grammar School. There he won a medal for science, but he was forced to leave because his parents could not afford the fees. After a year of private study, he began his working life in Newcastle in 1870 as a telegraph operator for an Anglo-Dutch cable company, but he had to give up after only four years because of increasing deafness. He therefore proceeded to spend his time studying theoretical aspects of electrical transmission and communication, and moved to Devon with his parents in 1889. Because the operation of many electrical circuits involves transient phenomena, he found it necessary to develop what he called operational calculus (which was essentially a form of the Laplace transform calculus) in order to determine the response to sudden voltage and current changes. In 1893 he suggested that the distortion that occurred on long-distance telephone lines could be reduced by adding loading coils at regular intervals, thus creating a matched-transmission line. Between 1893 and 1912 he produced a series of writings on electromagnetic theory, in one of which, anticipating a conclusion of Einstein's special theory of relativity, he put forward the idea that the mass of an electric charge increases with its velocity. When it was found that despite the curvature of the earth it was possible to communicate over very great distances using radio signals in the so-called "short" wavebands, Heaviside suggested the presence of a conducting layer in the ionosphere that reflected the waves back to earth. Since a similar suggestion had been made almost at the same time by Arthur Kennelly of Harvard, this layer became known as the Kennelly-Heaviside layer.[br]Principal Honours and DistinctionsFRS 1891.
