Descartes merged algebra and geometry
René Descartes' Cartesian coordinate system brilliantly unified algebra and geometry, transforming how we understand and solve mathematical problems, from ancient shapes to modern technology.
In 1637, René Descartes revolutionized mathematics by introducing the Cartesian coordinate system. This innovation assigned numerical coordinates to points on a plane, allowing geometric shapes like lines and curves to be represented as algebraic equations, and vice versa. Before this, algebra and geometry were separate disciplines, making complex problems difficult to solve.
