The coherence length of black
... coherence length is slightly less than the mean or effective wavelength. That is why no fringes (modulation of intensity) of order |m| � 1 occur. So, in the case of unfiltered black-body radiation, interference patterns consist only of a central maximum (m = 0) flanked by two weak minima (m = ± 21 , s ...

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"".
