On April 10 of 1813 in Paris, France Lagrange died. In the 77 years that he lived on this earth he did more things than anybody could have imagined they could do. As I have mentioned before he created something called the Lagrangian Mechanics which is based on Newton's Equations of Motion. In 1764, at the Paris Academy, Lagrange was credited for figuring out the M.3.12 Orbital Mechanics . Lagrange won an award for the best essay on the liberation of the moon with his analysis of a special case of the three-body problem, which uses the Lagrange points.
Lagrange points are where gravitational forces and the speed of motion of a body are in balance.
He also invented and brought to maturity the calculus of variations and later applied the new discipline to Celestial Mechanics. Lagrange created a method called the Lagrange multipliers as well. Lagrangian Polynomial is another method that Lagrange made. The Lagrangian Polynomial is the far easiest way to find a curve through points. Even though Lagrange is not as well known as Archimedes, Newton, and some other great mathematicians, he was one of the greatest mathematician of all times.
