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 pointer. In 1826, Johann Christian Poggendorff developed the mirror galvanometer for detecting electric currents. The apparatus is also known as a spot ...
In 1826, Poggendorff developed the mirror galvanometer, a device for detecting electric currents. He had an extraordinary memory, well stored with scientific knowledge, both modern and historical, a cool and impartial judgment, and a strong preference for facts as against theory of the speculative kind.
Mirror galvanometer systems are used as beam positioning or beam steering elements in laser scanning systems. For example, for material processing with high-power lasers, closed loop mirror galvanometer mechanisms are used with servo control systems. These are typically high power galvanometers and the newest galvanometers designed for beam ...

According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
An Ohio man allegedly slammed a 15-month-old girl on the floor after she wouldn’t stop crying, fracturing her skull. Two weeks later, she died of her injuries.
The mirror galvanometer proved yet another point of contention. Whitehouse wanted to work the cable with a very different scheme, [43] driving it with a massive high-voltage induction coil producing several thousand volts, so enough current would be available to drive standard electromechanical printing telegraphs used on inland telegraphs.

Frank Livoti Jr. said his father, Frank Livoti Sr., instantly recognized the significance of the intricate lighter and spent decades trying to locate its owner, whose initials “P.L. Shipley ...
