langley teriminin İngilizce İngilizce sözlükte anlamı
American astronomer and aviation pioneer who built the first successful heavier-than-air flying machines. He directed the Smithsonian Institution from 1887 to 1906
A unit of energy per unit area commonly employed in radiation theory Equal to one gram-calorie per square centimeter
A unit equal to one gram calorie per square centimeter of irradiated surface, used to measure solar radiation
{i} unit of solar radiation equivalent to one gram calorie per square centimeter of irradiated surface
Named for Samuel P Langley (1834-1906), a pioneering solar energy researcher at the Smithsonian Institution, this unit of radiant flux is one calorie per square centimeter (cal/cm2)
United States astronomer and aviation pioneer who invented the bolometer and contributed to the design of early aircraft (1834-1906)
A unit of energy per unit area, equal to 1 gramcalorie/cm² and commonly employed in radiation measurement
United States astronomer and aviation pioneer who invented the bolometer and contributed to the design of early aircraft (1834-1906) unit of solar radiation
born Aug. 22, 1834, Roxbury, Mass., U.S. died Feb. 27, 1906, Aiken, S.C. U.S. astronomer and aeronautics pioneer. He taught for many years at the future University of Pittsburgh. He studied the effect of solar activity on weather and invented the bolometer (1878), a radiant-heat detector sensitive to extremely small temperature differences. He began conducting experiments on lift and drag of wings by building flying machines, and in 1896 one of his heavier-than-air machines became the first to achieve sustained unmanned flight, flying 3,000 ft (900 m) along the Potomac River
