John William Strutt, 3rd Baron Rayleigh
John William Strutt, 3rd Baron Rayleigh, (; 12 November 1842 – 30 June 1919), was a British scientist who made extensive contributions to both theoretical and experimental physics. He spent all of his academic career at the University of Cambridge. Among many honors, he received the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies." He served as President of the Royal Society from 1905 to 1908 and as Chancellor of the University of Cambridge from 1908 to 1919.

where does argon come from and how is it extracted Argon comes from the air and it is produced industrially by the fractional distillation of liquid air in a cryogenic air separation unit can you state any of its features? It is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. It is chemically inert under most conditions and forms no confirmed stable compounds at room temperature. by whom was it discovered? Lord Rayleigh and Sir William Ramsay

John William Strutt, 3rd Baron Rayleigh [SEP] Introduction
He studied and described transverse surface waves in solids, now known as "Rayleigh waves". He contributed extensively to fluid dynamics, with concepts such as the Rayleigh number (a dimensionless number associated with natural convection), Rayleigh flow, the Rayleigh–Taylor instability, and Rayleigh's criterion for the stability of Taylor–Couette flow. He also formulated the circulation theory of aerodynamic lift. In optics, Rayleigh proposed a well known criterion for angular resolution. His derivation of the Rayleigh–Jeans law for classical black-body radiation later played an important role in birth of quantum mechanics (see Ultraviolet catastrophe). Rayleigh's textbook "The Theory of Sound" (1877) is still used today by acousticians and engineers.
