Lord Rayleigh (John W. Strutt)


John William Strutt, more commonly known as Lord Rayleigh, won the Nobel Prize in physics in 1904 "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies.” Lord Rayleigh’s work was in gas and molecular physics, however he dabbled in all of physics. He provided conclusive experiments on the gases in air and discovered argon, a component of air. His name is also associated with the explanation of why the sky is blue (Rayleigh scattering).
