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 (Russian: Георг Вильгельм Рихман; 22 July [O.S. 11 July] 1711 – 6 August [O.S. 26 July] 1753) was a Russian physicist of Baltic German origin who did pioneering work on electricity, atmospheric electricity, and calorimetry. [1]
A 300-foot kite raised antenna increased their radio range from 60 or 70 miles to 110 miles. [7] The United States Navy conducted kite antenna experiments on the torpedo boats USS Stringham and USS Bailey in 1911. [8] Some Signal Corps units conducted kite antenna experiments independently, often constructing their own kites. In June 1907 the ...
The experiment's purpose was to uncover then unknown facts about the nature of lightning and electricity. Reason A Bald Eagle swooned over the canvas, giving birth to an electric celebration of red white and blue, as Uncle Sam stuck his middle finger up at Zeus above, and Ben Franklin (surrounded by angels, because why not) tamed the Greek god ...
Franklin's experiment, in its initial conception, depended on the completion of Christ Church in Philadelphia, whose steeples would be sufficiently high as to attract a lightning strike. Franklin then conceived of an alternative experiment that involved flying a kite during a thunderstorm with a metal key attached to the string. [3]
The kite experiment was repeated by Romas, who drew from a metallic string sparks 9 feet (2.7 m) long, and by Cavallo, who made many important observations on atmospheric electricity. Lemonnier (1752) also reproduced Franklin's experiment with an aerial, but substituted the ground wire with some dust particles (testing attraction).
Forty-three primates remain on the loose in a South Carolina town, two days after escaping from a research laboratory, authorities said Friday. As of midday Friday, the monkeys "have not yet been ...
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. [101] If an experiment cannot be repeated to produce the same
