Sir James Hopwood Jeans, FRS, angleški matematik, fizik in astronom, * 11. september 1877, Ormskirk pri Southportu, grofija Lancashire, Anglija, † 17. september 1946, Dorking, grofija Surrey, Anglija.

Življenje in delo

Jeans je študiral na Univerzi v Cambridgeu. Od leta 1905 je živel v ZDA, od leta 1910 do 1912 je bil profesor za uporabno matematiko v Princetonu in Cambridgeu. Leta 1923 je bil raziskovalni sodelavec Observatorija Mount Wilson. Leta 1928 je bil povzdignjen v viteza.

Raziskoval je na področju dinamike in sevanja plinov. V kinetični teoriji plinov je dokazal zakon o enaki porazdelitvi energije in Maxwellov zakon porazdelitve hitrosti molekul. Na osnovi klasične teorije je izvedel enačbo, ki daje skupaj z Rayleighovo enačbo porazdelitev sevanja črnega telesa (Rayleigh-Jeansov približek).

V astronomiji je podal več teorij o kozmogoniji in leta 1917 ovrgel Laplaceovo teorijo o nastanku Osončja. Njegova teorija o nastanku Osončja s cigaro, ogromnim kosom snovi, ki ga je Soncu iztrgala bližnja zvezda, se ni dolgo obdržala zaradi male verjetnosti dogodka. Proučeval je teoretične astrofizikalne probleme. Bil je znan popularizator astronomije.
