  James Hopwood Jeans - Wikipedia, the free encyclopedia
Sir James Hopwood Jeans (September 11, 1877 in Ormskirk – September 16, 1946 in Dorking) was a British physicist, astronomer, and mathematician.
Jeans, along with Arthur Eddington, is a founder of British excellence in cosmology, a fact which persists down to the present day.
Jeans was the first to propose a steady state cosmology based on a hypothesized continuous creation of matter in the universe.

 Jeans mass - Wikipedia, the free encyclopedia
Jeans mass is named after the British physicist Sir James Jeans, who considered the process of gravitational collapse within a gaseous cloud.
He was able to show that, under appropriate conditions, a cloud, or part of one, would become unstable and begin to collapse when it lacked sufficient gaseous pressure support to balance the force of gravity.
In his formal analysis, Jeans assumed that the collapsing region of the cloud was surrounded by an infinite, static medium.

Sir James Hopwood Jeans (born Ormskirk, September 11, 1877, died Dorking, September 16, 1946) was a British physicist, astronomer and mathematician who was the first to propose the theory of continuous creation of matter in the universe.
Jeans was appointed a Lecturer in Mathematics at Cambridge in 1904, then he lectured at Princeton from 1905 until 1909 where he was Professor of Applied Mathematics.
Jeans, therefore, had a second organ installed in his Dorking home and, using his scientific skills, he designed the acoustics in his house to allow both his wife and himself to play their organs without disturbing each other.

The English mathematician, physicist, and astronomer Sir James Hopwood Jeans (1877-1946) made important contributions to the development of quantum theory and to theoretical astrophysics, especially to the theory of stellar structure.
On Sept. 11, 1877, James Jeans was born in Ormskirk, Lancashire, the son of a parliamentary journalist.
In 1904 he was appointed university lecturer in mathematics at Cambridge; and in 1906, at the very early age of 28, he was elected a fellow of the Royal Society--all this in spite of the fact that during 1902-1903 tuberculosis of the joints forced him to go to several sanatoriums.

 Jeans, James Hopwood (1877-1946)
Going on to astrophysics and cosmogony, he solved the problem of the behavior of rotating masses of compressible fluids, and addressed the origins of binary stars and the collapse of interstellar clouds (see Jeans length and Jeans mass).
With Harold Jeffreys he developed the tidal hypothesis of the origin of the planets, which, in the 1920s and 1930s, led to a sharp decline in optimism among professional astronomers about the prospects for life beyond the Solar System.
In 1929, Jeans abandoned research and became an outstanding popularizer of science and the philosophy of science.

 RECENT PHILOSOPHY: Philosophy Meets Modern Physics
Sir James Jeans (picture), one of the most eminent savants and an international authority in mathematics, theoretical physics and astronomy, has also been called "the Edgar Wallace of cosmology." Very few scientists of his rank have ever had his talents for combining profundity with a colorful, popular style.
Jeans himself was fond of fiction and detective stories, and he knew how to charm the public, although he never made a confession to his readers which he could not justify before his scientific conscience.
Towards the end of his life, Jeans became more and more convinced that the scientific viewpoint was synonymous with that of the astronomer.

In astronomy, mass that a cloud (or part of a cloud) of interstellar gas must have before it can contract under its own weight to form a protostar.
The Jeans mass is an expression of the Jeans criterion, which says that a cloud will contract when the gravitational force tending to draw material towards its centre is greater than the opposing force due to gas pressure.
It is named after English mathematician James Hopwood Jeans, whose work focused on the kinetic theory of gases and the origins of the cosmos.

The Jeans velocity of a perturbation and the Jeans escape are two unrelated concepts named in honor of the same mathematician and astronomer at the turn of the XX century, who was also known for his popular works on astronomy.
The velocity of motion of this perturbation throughout the cloud is called the "Jeans velocity" in honor of Sir James Hopwood Jeans, who developed the theory.
