Alan Arnold Griffith was born
Alan Arnold Griffith was an English engineer and the son of Victorian science fiction writer George Griffith. Among many other contributions, he is best known for his work on stress and fracture in metals that is now known as metal fatigue, as well as being one of the first to develop a strong theoretical basis for the jet engine.
James Clerk Maxwell was born
James Clerk Maxwell was a Scottish mathematician and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" where the first one had been realised by Isaac Newton.
Thomas Young was born
Having been described as "The Last Man Who Knew Everything", British polymath Thomas Young made notable contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. Among his many achievements, Young described the characterization of elasticity that came to be known as Young's modulus (denoted as E).
