Comment on half-integer quantum numbers for the total angular
... To consider the photon trajectory in a helical beam we note that the trajectory may be conceived as the saddlepoint solution of a path-integral representation of the wavemechanics, and this is given by the Eikonal equation. This equation says that the photons choose the path between two points in sp ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
