Georg Wilhelm Richmann was born 22 July [O.S. 11 July] 1711 in the city of Pernau in Livonia, Swedish Empire (now Estonia). Richmann's father died of plague before he was born, and his mother remarried. In his early years he studied in Reval (now Estonia); later he studied in Germany at the universities of Halle and Jena.
An attempt to replicate the experiment killed Georg Wilhelm Richmann in Saint Petersburg in August 1753; he was thought to be the victim of ball lightning. [4] Franklin himself is said to have conducted the experiment in June 1752, supposedly on the top of the spire on Christ Church in Philadelphia. However, the spire at Christ Church was not ...
Crucially, experimental and theoretical results must be reproduced by others within the scientific community. Researchers have given their lives for this vision; Georg Wilhelm Richmann was killed by ball lightning (1753) when attempting to replicate the 1752 kite-flying experiment of Benjamin Franklin. [96]
Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...
February 17 – The concept of electrical telegraphy is first published in the form of a letter from 'C. M.' to The Scots' Magazine. [8] Benjamin Franklin invents the lightning rod, to ring a bell when struck by lightning, following his 1752 kite and key tests. George Semple uses hydraulic lime cement in rebuilding Essex Bridge in Dublin.
Richmann's law. Richmann's law, [1][2] sometimes referred to as Richmann's rule, [3] Richmann's mixing rule, [4] Richmann's rule of mixture[5] or Richmann's law of mixture, [6] is a physical law for calculating the mixing temperature when pooling multiple bodies. [5] It is named after the Baltic German physicist Georg Wilhelm Richmann, who ...

A 1753 report recounts lethal ball lightning when professor Georg Richmann of Saint Petersburg, Russia, constructed a kite-flying apparatus similar to Benjamin Franklin's proposal a year earlier. Richmann was attending a meeting of the Academy of Sciences when he heard thunder and ran home with his engraver to capture the event for posterity ...
