Leon Brillouin (physicist)

Leon Brillouin was a French-American physicist renowned for his work in wave physics, particularly in understanding how waves—such as light and sound—interact with materials. He contributed to the development of fiber optics and signal processing, including concepts like Brillouin scattering, a phenomenon used in measuring material properties and in telecommunications. His work helped improve the transmission of information and our understanding of how waves travel through different media, making technologies like high-speed internet possible. Brillouin's research bridged fundamental physics and practical applications, significantly advancing both scientific knowledge and technological innovation.
