Weizsäcker, Carl Friedrich von (1912–2007)
German physicist and philosopher at the University of Strasbourg who, in
1944, published an important new version of the nebular
hypothesis which explained the puzzling discrepancy between the comparatively
low angular momentum of the Sun
and the high angular momentum of the outer planets. Previously, in 1938,
he had put forward, independently of Hans Bethe,
the carbon-nitrogen-oxygen cycle as an important
energy-making process in stars. Related category
