George H. Bryan

George Hartley Bryan, usually cited GH Bryan, (* 1864 in Cambridge, † October 13, 1928 in Bordighera, Italy ) was a British physicist.

Bryan studied at Cambridge (PhD 1895) and was professor of mathematics at University College, Bangor.

He wrote 1903 articles thermodynamics in the Encyclopedia of Mathematical Sciences and was also charged with Joseph Larmor of the British Association for the Advancement of Science, to write summary reports on the state of thermodynamics and statistical mechanics (presented in 1891, 1894). At the meeting of the British Association at Oxford in 1894, there was also a meeting of the English physicist Ludwig Boltzmann, who was celebrated there. In 1894 and 1895 he also published two works with Boltzmann. In thermodynamics, Bryan was the first to point to the need to introduce the internal energy as an independent variable.

But he is best known as one of the first subjects derive the correct equations for the stability of aircraft in flight. This happened in 1911 in his book Stability in aviation ( Macmillan ), eight years after the first flight of the Wright brothers. He examined 1888 the liquid flow in tubes.

He was a Fellow of the Royal Society. In 1889 he received the Smith Price, 1901, the Gold Medal of the British Shipbuilding Technology Society and the 1920 Hopkins price.
