Measurement of Orbital Angular Momentum in Optical
... Optical tweezers are an optical trap produced by a laser beam that is tightly focused.1 Some microscopic particles experience a gradient force towards this focus and can thus be trapped. Particles that are trapped are collected and held by the transfer of linear momentum from the laser beam to the p ...

longitudinal plasma oscillations in an electric field
... We now adopt a different point of view. Instead of assuming the fluctuations to have an amplitude small enough to permit complete linearization, we suppose that as a consequence of BUNEMAN’S mechanism a kind of quasi-equilibrium is established in which fo and F, are nearly time-independent. This can ...

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"".
