18th and 19th Century Mathematicians

Pierre-Louis de Maupertuis introduced the concept of the calculus of variations in his 1744 work, "Essai de cosmologie."

Thomas Bayes is renowned for his contributions to probability theory, particularly Bayes' theorem, which provides a method for updating beliefs in light of new evidence.

Leonhard Euler derived the Euler-Lagrange equation, a fundamental equation in the calculus of variations, in his 1744 work, "Methodus inveniendi lineas curvas maximi minimive proprietate gaudentes."

Pierre-Simon Laplace introduced the Laplace transform, a mathematical tool used to solve differential equations, in his 1785 work, "Théorie analytique des probabilités."

Charles-Augustin de Coulomb made significant contributions to the theory of elasticity, particularly in his study of the torsion of wires.

Abraham de Moivre introduced the concept of the generating function in his 1730 work, "Miscellanea Analytica."

Jean le Rond d'Alembert made significant contributions to the theory of differential equations, including his work on the wave equation.

Caspar Wessel made significant contributions to the theory of complex numbers, including his work on the geometric representation of complex numbers.

Pierre-Simon Laplace made significant contributions to the theory of determinants, including his work on the Laplace expansion.
