 Jacques Philippe Marie Binet

Jacques Philippe Marie Binet, commonly known as Jacques Binet, was a French mathematician known for his contributions to several areas of mathematics, particularly in the fields of geometry and calculus. He is also recognized for his work in the development of mathematical notation. Binet's most notable contribution is the Binet's formula, which provides a closed-form expression for the Fibonacci numbers. This formula allows the calculation of the nth Fibonacci number without needing to calculate all the preceding numbers.
