Alexis Claude ClairautDied 17 May 1765 at age 52 (born 7 May 1713).French mathematician who, as a child prodigy at age ten was studying calculus, tutored by his father. Clairaut read his first paper, Quatre problèmes sur de nouvelles courbes to the Paris Academy (1726) at the age of 13. He accompanied Maupertuis on an expedition to Lapland to measure the length of the meridian. From this experience, he began a book (1743) on the shape of the rotating earth under the influences of gravity and centrifugal forces. Further, he showed how to measure the shape by use of measurements of the effect of gravity at different location on the swing of a pendulum. He also determined the first reasonable value for the mass of Venus, an improved value for the mass of the moon, and predicted the timing of the return of Halley's Comet. |
