Euler's work was instrumental in the development of the field of calculus. He introduced the concept of the "e" constant, now known as Euler's Number.
Euler's contributions include the development of the Euler-Lagrange equation, which is used to describe fluid flow in physics.
Euler's work in geometry led to the development of the Euler characteristic of a polyhedron, which is a fundamental concept in topology.
