Bonaventura CavalieriDied 30 Nov 1647 (born 1598). Italian mathematician who made developments in geometry that were precursors to integral calculus. Cavalieri's theory of indivisibles, presented in his Geometria indivisibilis continuorum nova (1635) was a development of Archimedes' method of exhaustion incorporating Johannes Kepler's theory of infinitesimally small geometric quantities. The area and volume of various geometric figures can easily be found with this method. He was largely responsible for introducing logarithms as a computational tool in Italy through his book Directorium Generale Uranometricum, including logarithms of trigonometric functions for astronomers. He also wrote on optics and astronomy. Galileo thought highly of his writing, and corresponded with him. |
