Late 19th or early 20th century. This galvanometer was used at the transatlantic cable station, Halifax, NS, Canada Modern mirror galvanometer from Scanlab. A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless ...
William Thomson (1760 – November 1806) was an English mineralogist, who used the name Guglielmo Thomson in Italy in later life. He died in Palermo at the age of 46 ...
James Thomson is known for his work on the improvement of water wheels, water pumps and turbines. Also his innovations in the analysis of regelation, i.e., the effect of pressure on the freezing point of water, and his studies in glaciology including glacier motion, where he extended the work of James David Forbes.
A vibration galvanometer is a type of mirror galvanometer, usually with a coil suspended in the gap of a magnet or with a permanent magnet suspended in the field of an electromagnet. The natural oscillation frequency of the moving parts is carefully tuned to a specific frequency; commonly 50 or 60 Hz. Higher frequencies up to 1 kHz are possible.
With Edwin J. Houston, a former teacher and later colleague of Thomson's at Central High School, Thomson founded the Thomson-Houston Electric Company.Notable inventions created by Thomson during this period include an arc-lighting system, an automatically regulated three-coil dynamo, a magnetic lightning arrester, and a local power transformer.

The Greatest Video Game Music, performed by the London Philharmonic Orchestra, features classical orchestrations of video game themes including those from Super Mario Bros., Call of Duty, Metal Gear Solid, Final Fantasy, Halo, World of Warcraft, Angry Birds and many more. [1] A sequel, The Greatest Video Game Music 2, was released a year later.
However, it was not until late 2011 that Thompson began actively pursuing the idea of creating a branded YouTube channel devoted to life hack videos. A few years prior, a friend of Thompson's had told him that he was the "King of Random" because of all of the random things he was always involved with.
William Thomson, 1st Baron Kelvin (26 June 1824 – 17 December 1907 [7]), was a British mathematician, mathematical physicist and engineer. [8] [9] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research and mathematical analysis of electricity, was instrumental in the formulation of the first and second ...
