John Scott Russell

Definition

John Scott Russell was a 19th-century Scottish engineer and naval architect, best known for his pioneering work in fluid dynamics and wave theory. His most significant contribution is the discovery of solitons, which are self-reinforcing solitary waves that maintain their shape while traveling at constant speeds. This discovery not only advanced the understanding of wave phenomena but also laid the groundwork for modern research into nonlinear waves and their applications in various fields.
