Charles Louis Alphonse Poinsot

Charles Louis Alphonse Poinsot was a 19th-century French mathematician and physicist known for his work in optics and mathematics. He studied how light behaves and contributed to understanding the wave nature of light, challenging earlier particle theories. His research helped pave the way for modern optics and wave theory, influencing scientific thought about light and its properties. Poinsot’s work combined mathematical rigor with physical insight, making significant contributions to both theoretical and applied physics during his lifetime.
