George Hartley Bryan (1864-1928)

George Hartley Bryan , mostly quoted by 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 in Bangor .

He wrote the article Thermodynamics in the Encyclopedia of Mathematical Sciences in 1903 and was also commissioned with Joseph Larmor of the British Association for the Advancement of Science to write summarizing reports on the state of thermodynamics and statistical mechanics (submitted 1891, 1894). At the meeting of the British Association in Oxford in 1894, the English physicists also met Ludwig Boltzmann , who was celebrated there. In 1894 and 1895 he also published two papers with Boltzmann. In thermodynamics, Bryan was the first to point out the need to introduce internal energy as an independent quantity.

But he is best known as one of the first to derive the correct equations for the stability of aircraft in flight. It did so in his 1911 book Stability in Aviation (Macmillan), eight years after the Wright brothers' first flight . In 1888 he also studied the flow of liquids in tubes.

He was a Fellow of the Royal Society . In 1889 he received the Smith Prize, in 1901 the gold medal of the British Shipbuilding Society and in 1920 the Hopkins Prize.
