Bonaventura Cavalieri


Quick Reference


Italian mathematician known for his method of ‘indivisibles’ for calculating areas and volumes. In his method, an area is thought of as composed of lines and a volume as composed of areas. Here can be seen the beginnings of the ideas of integral calculus. The following theorem of his is typical of the approach: Two solids have the same volume if they have equal altitudes and if sections parallel to and at the same distance from the base have equal areas.
