method of indivisibles

Quick Summary

The method of indivisibles is a mathematical concept developed by Bonaventura Cavalieri in the 17th century. It is considered a precursor to integral calculus. This method involves viewing geometric figures as being composed of an infinite number of infinitesimally small components, or "indivisibles".12

For example, Cavalieri proposed that a plane figure could be seen as a collection of indivisible lines, and a solid figure as a collection of indivisible areas. By comparing these collections of indivisibles, mathematicians could determine areas and volumes. This approach allowed for the calculation of areas under curves, such as parabolas, and volumes of solids like cones.2

While innovative, Cavalieri's method faced criticism for its lack of rigor. However, it laid important groundwork for the development of calculus by mathematicians like Isaac Newton and Gottfried Wilhelm Leibniz.12
