Josef-Louis Lagrange

Joseph-Louis Lagrange was an 18th-century mathematician and astronomer who made significant contributions to celestial mechanics, the study of the movements of celestial bodies. He is best known for Lagrange's equations, which help predict the motion of planets and moons under gravitational forces. Lagrange also studied the stability of orbits and identified Lagrangian points—positions in space where objects can maintain a stable position relative to two larger bodies, like the Earth and the Moon. His work laid the groundwork for modern astrophysics and engineering, merging mathematics with practical applications in understanding the universe's dynamics.
