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 ...
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.
The news of the death of Georg Wilhelm Richmann, a professor in St. Petersburg who was killed by lightning in 1753 during his attempt at measuring the intensity of the electric field in the atmosphere, caused Diviš to become interested in atmospheric electricity. [4]
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. [ 2 ] A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. [ 3 ]
The kite was invented in China, possibly as far back as the 5th century BC by Mozi (also Mo Di) and Lu Ban (also Gongshu Ban). [14] These leaf kites were constructed by stretching silk over a split bamboo framework. The earliest known Chinese kites were flat (not bowed) and often rectangular. Later, tailless kites incorporated a stabilizing ...
A box kite is a high-performance kite, noted for developing relatively high lift; it is a type within the family of cellular kites. The typical design has four parallel struts. The box is made rigid with diagonal crossed struts. There are two sails, or ribbons, whose width is about a quarter of the length of the box.
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 ...
