... What are nonlinear optical effects and why do they occur? Sending infrared light into a crystal yielded this display of green light (second-harmonic generation): Nonlinear optics allows us to change the colour of a light beam, to change its shape in space and time, and to create ultrashort laser pul ...
Introduction I. Waves on a String
... A hand steadily wiggles the left end of the string up and down. The figure below shows snapshots of the wave on the string at three instants in time (t1, t2, t3) as the wave travels to the right. The dot painted on the string is indicated at point 1. The pictures below show two possible physical sit ...

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"".
