Ink drawing by Sean Keating of Erwin Schrodinger (1887-1961). Schrodinger founded wave mechanics, creating Schrodinger's equation. Louis-Victor Pierre-Raymond de Broglie had discovered the wave nature of particles when he realised that all particles have asociated waves. The properties of the particle are the result of a combination of its particle-like and wave-like nature. Schrodinger shared the Nobel Prize for physics in 1933, with the British theoretical physicist Paul Dirac, for his wave equation.
