Joseph-Louis Lagrange was an 18th-century mathematician who made major contributions to mechanics, calculus, and algebra. One of his key contributions is Lagrange's Theorem in group theory, which states that the order (number of elements) of any subgroup of a finite group divides the order of the group.

In calculus of variations, Lagrange introduced the Lagrangian function, used to find paths or functions that minimize (or maximize) quantities. This is foundational in Lagrangian mechanics, an alternative to Newton’s laws, where the motion of a system is described using energy functions instead of forces.

In interpolation, Lagrange Polynomial is a method to estimate a function using a set of known data points. It’s widely used in numerical analysis.

Overall, Lagrange’s ideas are essential in physics, engineering, and mathematics, especially in mechanics, optimization, and abstract algebra.
