Early Estimates of the Velocity of Light
... Early Estimates of the Velocity of Light If one assumes that about a thirtieth of a second is the minimum time interval distinguishable by the unaided eye, then the experiment of GALILEO could at best be said to have established for the velocity of light a lower limit of the order of some sixty mi. ...

Acoustooptic interaction of two light beams in a paratellurite crystal
... We performed an experimental investigation on a paratellurite AO cell where a slow shear acoustic wave was excited by a piezoelectric transducer made from xcut lithium niobate. The calculation has shown that, when the length of the piezoelectric transducer is l = 1.4 cm and the ultrasonic frequency ...

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"".
