Light Propagation with Phase Discontinuities
... r ) is the local index of refraction, and readily gives the laws of reflection and refraction between two media. In its most general form, Fermat’s principle can be stated as the principle of stationary phase (6–8); that is, the derivative of the phase ∫BA dϕ(→ r ) accumulated along the actual light ...

... a case the first two possibilities - when both photons are transmitted (Fig.1a) or reflected (Fig.1b) - cannot be distinguished from one another because there is always one photon in either output mode. As a result, the two possibilities are coherently superposed. Due to unitarity of the beam-splitt ...

All the familiar optical phenomena, such as straight line propagation, reflection and refraction could be explained by that corpuscular hypothesis.

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"".
