The Scientific Papers of Sir George Darwin: Supplementary Volume (Cambridge Library Collection - Physical Sciences)

Sir George Darwin (1845-1912) was the second son of Charles Darwin. After studying mathematics at Cambridge he read for the Bar, but soon returned to science and to Cambridge, where in 1883 he was appointed Plumian Professor of Astronomy and Experimental Philosophy. His work was concerned primarily with the effect of the sun and moon on tidal forces on Earth, and with the theoretical cosmogony which evolved from practical observation: he formulated the fission theory of the formation of the moon (that the moon was formed from still-molten matter pulled away from the Earth by solar tides). He also developed a theory of evolution for the Sun-Earth-Moon system based on mathematical analysis in geophysical theory. This volume, published in 1916 after the author's death, includes a biographical memoir by his brother Sir Francis Darwin, his inaugural lecture and his lectures on George W. Hill's lunar theory.
