    SUBJECT AREA: Electricity
    [br]
    b. 1834 Tours, France
    d. 1910 Paris, France
    [br]
    French physicist, investigator of alternating-current wave-forms.
    [br]
    Joubert became Professor of Physics in the Collège Rollin, Paris, in 1874, a position he held until 1888. He was at one time General Secretary of the Société Française de Physique. In collaboration with Pasteur he began studies into the theories of germs and bacteria. In 1880 Joubert carried out research on wave-forms in alternating-current arc-lighting circuits. Reinventing a method previously used by earlier experimenters, including Wheatstone, he was, by a mechanical sampling technique, able to determine the voltage at different points in the cycle. By using a rotating contact on the alternator shaft, the angular position of which could be varied, the whole of the wave-form could be delineated. This successful technique was widely used for some thirty years.

  • 14 Appleton, Sir Edward Victor

    [br]
    b. 6 September 1892 Bradford, England
    d. 21 April 1965 Edinburgh, Scotland
    [br]
    English physicist awarded the Nobel Prize for Physics for his discovery of the ionospheric layer, named after him, which is an efficient reflector of short radio waves, thereby making possible long-distance radio communication.
    [br]
    After early ambitions to become a professional cricketer, Appleton went to St John's College, Cambridge, where he studied under J.J.Thompson and Ernest Rutherford. His academic career interrupted by the First World War, he served as a captain in the Royal Engineers, carrying out investigations into the propagation and fading of radio signals. After the war he joined the Cavendish Laboratory, Cambridge, as a demonstrator in 1920, and in 1924 he moved to King's College, London, as Wheatstone Professor of Physics.
    In the following decade he contributed to developments in valve oscillators (in particular, the "squegging" oscillator, which formed the basis of the first hard-valve time-base) and gained international recognition for research into electromagnetic-wave propagation. His most important contribution was to confirm the existence of a conducting ionospheric layer in the upper atmosphere capable of reflecting radio waves, which had been predicted almost simultaneously by Heaviside and Kennelly in 1902. This he did by persuading the BBC in 1924 to vary the frequency of their Bournemouth transmitter, and he then measured the signal received at Cambridge. By comparing the direct and reflected rays and the daily variation he was able to deduce that the Kennelly- Heaviside (the so-called E-layer) was at a height of about 60 miles (97 km) above the earth and that there was a further layer (the Appleton or F-layer) at about 150 miles (240 km), the latter being an efficient reflector of the shorter radio waves that penetrated the lower layers. During the period 1927–32 and aided by Hartree, he established a magneto-ionic theory to explain the existence of the ionosphere. He was instrumental in obtaining agreement for international co-operation for ionospheric and other measurements in the form of the Second Polar Year (1932–3) and, much later, the International Geophysical Year (1957–8). For all this work, which made it possible to forecast the optimum frequencies for long-distance short-wave communication as a function of the location of transmitter and receiver and of the time of day and year, in 1947 he was awarded the Nobel Prize for Physics.
    He returned to Cambridge as Jacksonian Professor of Natural Philosophy in 1939, and with M.F. Barnett he investigated the possible use of radio waves for radio-location of aircraft. In 1939 he became Secretary of the Government Department of Scientific and Industrial Research, a post he held for ten years. During the Second World War he contributed to the development of both radar and the atomic bomb, and subsequently served on government committees concerned with the use of atomic energy (which led to the establishment of Harwell) and with scientific staff.

  • 18 Ayrton, William Edward

    [br]
    b. 14 September 1847 London, England
    d. 8 November 1908 London, England
    [br]
    English physicist, inventor and pioneer in technical education.
    [br]
    After graduating from University College, London, Ayrton became for a short time a pupil of Sir William Thomson in Glasgow. For five years he was employed in the Indian Telegraph Service, eventually as Superintendent, where he assisted in revolutionizing the system, devising methods of fault detection and elimination. In 1873 he was invited by the Japanese Government to assist as Professor of Physics and Telegraphy in founding the Imperial College of Engineering in Tokyo. There he created a teaching laboratory that served as a model for those he was later to organize in England and which were copied elsewhere. It was in Tokyo that his joint researches with Professor John Perry began, an association that continued after their return to England. In 1879 he became Professor of Technical Physics at the City and Guilds Institute in Finsbury, London, and later was appointed Professor of Physics at the Central Institution in South Kensington.
    The inventions of Avrton and Perrv included an electric tricycle in 1882, the first practicable portable ammeter and other electrical measuring instruments. By 1890, when the research partnership ended, they had published nearly seventy papers in their joint names, the emphasis being on a mathematical treatment of subjects including electric motor design, construction of electrical measuring instruments, thermodynamics and the economical use of electric conductors. Ayrton was then employed as a consulting engineer by government departments and acted as an expert witness in many important patent cases.

    Ives gained his PhD in physics from Johns Hopkins University, Baltimore, Maryland, and subsequently served in the US Signal Corps, eventually gaining experience in aerial photography. He then joined the Western Electric Engineering Department (later Bell Telephone Laboratories), c.1920 becoming leader of a group concerned with television-image transmission over telephone lines. In 1927, using a Nipkow disc, he demonstrated 50-line, 18 frames/sec pictures that could be displayed as either 2 in.×2 1/2 in. (5.1 cm×6.4 cm) images suitable for a "wirephone", or 2 ft ×2 1/2 ft (61 cm×76 cm) images for television viewing. Two years later, using a single-spiral disc and three separately modulated light sources, he was able to produce full-colour images.

  • 20 Popov, Aleksandr Stepanovich

    [br]
    b. 16 March 1859 Bogoslavsky, Zamod, Ural District, Russia
    d. 13 January 1906 St Petersburg, Russia
    [br]
    Russian physicist and electrical engineer acclaimed by the former Soviet Union as the inventor of radio.
    [br]
    Popov, the son of a village priest, received his early education in a seminary, but in 1877 he entered the University of St Petersburg to study mathematics. He graduated with distinction in 1883 and joined the faculty to teach mathematics and physics. Then, increasingly interested in electrical engineering, he became an instructor at the Russian Navy Torpedo School at Krondstadt, near St Petersburg, where he later became a professor. On 7 May 1895 he is said to have transmitted and received Morse code radio signals over a distance of 40 m (130 ft) in a demonstration given at St Petersburg University to the Russian Chemical Society, but in a paper published in January 1896 in the Journal of the Russian Physical and Chemical Society, he in fact described the use of a coherer for recording atmospheric disturbances such as lightning, together with the design of a modified coherer intended for reception at a distance of 5 km (3 miles). Subsequently, on 26 November 1897, after Marconi's own radio-transmission experiments had been publicized, he wrote a letter claiming priority for his discovery to the English-language journal Electrician, in the form of a translated précis of his original paper, but neither the original Russian paper nor the English précis made specific claims of either a receiver or a transmitter as such. However, by 1898 he had certainly developed some form of ship-to-shore radio for the Russian Navy. In 1945, long after the Russian revolution, the communist regime supported his claim to be the inventor of radio, but this is a matter for much debate and the priority of Marconi's claim is generally acknowledged outside the USSR.
