Per Wikipedia Sir James Hopwood Jeans Om Frs 1877 - 1946 Was An English Physicist Mathematician And An Astronomer. He Served As A Secretary Of The Royal Society From 1919 To 1929 And Was The President Of The Royal Astronomical Society From 1925 To 1927 And Won Its Gold Medal.Jeans Was Elected Fellow Of Trinity College In October 1901 And Taught At Cambridge But Went To Princeton University In 1904 As A Professor Of Applied Mathematics. He Returned To Cambridge In 1910. From 1923 To 1944 He Was Associated With Caltech's Mount Wilson Observatory. He Made Important Contributions In Many Areas Of Physics Including Quantum Theory The Theory Of Radiation And Stellar Evolution. Jeans Along With Arthur Eddington Is A Founder Of British Cosmology. His Scientific Reputation Is Grounded In The Monographs The Dynamical Theory Of Gases 1904 Theoretical Mechanics 1906 And Mathematical Theory Of Electricity And Magnetism 1908. After Retiring In 1929 He Wrote A Number Of Books For The Lay Public. One Of Jeans's Major Discoveries Named The Jeans Length Is A Critical Radius Of An Interstellar Cloud In Space. It Depends On The Temperature And Density Of The Cloud And The Mass Of The Particles Composing The Cloud. A Cloud That Is Smaller Than Its Jeans Length Will Not Have Sufficient Gravity To Overcome The Repulsive Gas Pressure Forces And Condense To Form A Star Whereas A Cloud That Is Larger Than Its Jeans Length Will Collapse. Jeans Came Up With Another Version Of This Equation Called The Jeans Mass Or The Jeans Instability That Solves For The Critical Mass A Cloud Must Attain Before Being Able To Collapse. Jeans Also Helped To Discover The Rayleigh-Jeans Law Which Relates The Energy Density Of Black-Body Radiation To The Temperature Of The Emission Source. Jeans Is Also Credited With Calculating The Rate Of Atmospheric Escape From A Planet Due To Kinetic Energy Of The Gas Molecules A Process Known As Jeans Escape. <br/> <br/> Cambridge University Press hardcover
