From Wikipedia, the free encyclopedia
The year 1783 in science and technology involved some significant events:
Astronomy
- February 26 â Caroline Herschel discovers NGC 2360.
- May â John Goodricke presents his conclusions that the variable star Algol is what comes to be known as an eclipsing binary to the Royal Society of London.
- August 18 â Great Meteor passes over Great Britain, exciting scientific interest.[1][2]
- November 27 â John Michell proposes the existence of black holes ("dark stars").[3]
- Jérôme Lalande publishes a revised edition of John Flamsteedâs star catalogue in an ephemeris, Ãphémérides des mouvemens célestes, numbering the stars consecutively by constellation, the system which becomes known as "Flamsteed designations".[4]
Aviation
- June 5 â The Montgolfier brothers send up at Annonay, near Lyon, a 900 m linen hot air balloon as a public demonstration. Its flight covers 2 km and lasts 10 minutes, to an estimated altitude of 1600â2000 metres.[5]
- August 27 â Jacques Charles and the Robert brothers launch the first hydrogen balloon in Paris.

- Erasmus Darwin begins publication of A System of Vegetables, a translation of Linnaeus in which he coins many common English language names of plants.
Chemistry
- Antoine Lavoisier publishes Réflexions sur le phlogistique, showing the phlogiston theory to be inconsistent, proposing chemical reaction as an alternative theory in a paper read to the French Academy of Sciences in June, names hydrogen and demonstrates that water is a compound and not an element.[6]
- Discovery of tungsten â José and Fausto Elhuyar find an acid in wolframite which they reduce with charcoal to isolate tungsten.
Earth sciences
- February 5âMarch 28 â Calabrian earthquakes in Kingdom of Two Sicilies.
- June 8 â The volcano Laki in Iceland begins a major eruption with extensive climatic consequences on both sides of the Atlantic Ocean.[7]
- August 4 (Edo period, Tenmei 3) â Mount Asama, the most active volcano in Japan, begins climactic eruption, exacerbating a famine, following a plinian eruption beginning on May 9 (Tenmei eruption).
History of science and technology
- German physician Melchior Adam Weikard publishes a biography of microscopist Wilhelm Friedrich von Gleichen, Biographie des Herrn Wilhelm Friedrich v. Gleichen genannt RuÃwurm.
Physics
- Jean-Paul Marat publishes Mémoire sur l'électricité médicale ("Memorandum on Medical Electricity").
Technology
- Henry Cort of Funtley, England, invents the grooved rolling mill for producing bar iron.[8]
- Thomas Bell patents a method of printing on fabric from engraved cylinders.[9][10]
- Horace-Bénédict de Saussure publishes Essai sur l'hygrométrie, recording his experiments with the hair hygrometer.
