• Lagrange submits a paper on the movements of Jupiter's satellites to the French Academy of Sciences.

Biology

• Moses Harris publishes The Aurelian, or, Natural History of English Insects; Namely, Moths and Butterflies.

Exploration

• November 15 – Louis Antoine de Bougainville leaves Nantes for a three-year circumnavigation of the world with the ships La Boudeuse and Étoile; the botanist Philibert Commerçon is on board.

Mathematics

• Arima Yoriyuki finds a rational approximation of $\pi$, correct to 29 digits.^[1][2]
• Euler gives up his post as director of mathematics at the Prussian Academy of Sciences and returns to Saint Petersburg. On the recommendation of Euler and d'Alembert, Lagrange succeeds him in Berlin, where he will stay for over twenty years.

Medicine

• October – Addenbrooke's Hospital, Cambridge, England, completed.

Metallurgy

• The Cranege brothers experiment with the use of the reverberatory furnace for the production of wrought iron from cast iron using coal fuel at the Coalbrookdale iron works under the sponsorship of Richard Reynolds in England.
