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 ...
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 ...
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] If an experiment cannot be repeated to produce the same results
Prokop Diviš Theatre in Žamberk with "machina meteorologica" on the top. Prokop Diviš O.Praem.

The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself. A complete original version of the Einstein-de Haas experimental equipment was donated by Geertruida de Haas-Lorentz , wife of de Haas and daughter of Lorentz, to the Ampère Museum in Lyon France in 1961 where it is currently on ...
The anode is the electrode at the bottom. A Crookes tube (also Crookes–Hittorf tube) [1] is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes [2] and others around 1869–1875, [3] in which cathode rays, streams of electrons, were discovered.

The Bothe–Geiger experiment and the Compton–Simon experiment marked an end to the BKS theory. [8] Kramers was skeptic at the beginning. In a letter to Bohr, Kramers said "I can unfortunately not survey how convincing the experiments of Bothe and Geiger actually are for the case of the Compton effect". [5]
