(18059) Cavalieri Main-belt Asteroid
Discovered on 15 December 1999 by P. G. Comba at Prescott.
Bonaventura Cavalieri (1598-1647) was a friar and a professor at the University of Bologna. He developed the method of indivisibles, which enabled him to find integrals of polynomials and centers of gravity of many curvilinear figures. His work ultimately influenced Leibniz' discovery of the calculus.Naming citation (20010309/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
