James Jean

Sir James Hopwood Jeans (September 11th 1877 with Ormskirk - September 16th 1946 with Dorking) was a Physicien, Astronome, and British Mathématicien.

Biography

Formed with the school Merchant Taylors with Northwood then with the Trinity College, it finished second of the university to the Tripos of mathematics in 1898. He taught in Cambridge, but came to the Université from Princeton in 1904 as mathematics professor applied. He went back to Cambridge in 1910.

He made important contributions in several fields of the physics, of which the Quantum theory, the theory of the Rayonnement and the stellar evolution. Its analysis of the bodies in rotation led it to conclude that the theory of Laplace according to which the solar system was made of only one gas cloud was incorrect, proposing in the place that the planets were formed starting from materials torn off with the sun by a hypothetical catastrophic quasi-collision with a star of passage. This theory is now abandoned.

Jean with Arthur Eddington, is considered to be at the origin of British excellence in cosmology, a fact which persisted until our days. Jean was the first to propose a stationary cosmology based on a hypothetical continuous creation of matter in the universe. This theory fell in disuse when the discovery in 1965 of the cosmological diffuse Fond was largely interpreted like the revealing signature of the Big Bang.

Its scientific reputation is registered in the monographs the dynamic theory of the gases (1904), theoretical Mécanique (1906) and mathematical Theorie of electricity and magnetism (1908). After its retirement in 1929, it wrote several books for the profane public, of which stars in their race (1931), universe around us , Through space and time (1934), new bases of sciences (1933) and mysterious universe . These books made Jeans rather well-known like popularizer of the revolutionary scientific discoveries of his time, particularly in Relativité and Cosmologie.

It Maria twice, the first time with the American poetess Charlotte Mitchell in 1907, then with the organ ist and Harpsichord Austrian ist Suzanne Hock (better known under the name of Susi Jean) in 1935.

To the school Merchant Taylors, the academic purse James Jeans is allotted to a candidate with the examinations of entry who obtains exceptional results on the whole of the subjects, and particularly in mathematics and sciences.

Quotations

  • The flood of knowledge points towards a reality not-mechanics; the universe starts to resemble more one great thought that with a machine. The spirit does not appear any more to be one accidental intruder in the field of the matter… us should rather greet it like the creator and the governor of the field of the matter.

  • The life exists in the universe only because the carbon atom has certain properties exceptionnelles." ( mysterious universe ).

  • Concerning the voyage in last time: There is necessary to remain more motionless than motionless. ( Through time and space ).
