- Pierre-Simon Laplace completes his study of gravitation, the stability of the solar system, tides, the precession of the equinoxes, the libration of the Moon, and Saturn's rings in Mecanique Celeste.
- Richard Harlan publishes Fauna Americana.
- Charles Waterton publishes Wanderings in South America, the North-west of the United States, and the Antilles, in the years 1812, 1816, 1820, and 1824; with original instructions for the perfect preservation of birds, &c. for cabinets of natural history.
- Cox's Orange Pippin apple cultivar first grown, at Colnbrook in Buckinghamshire, England, by horticulturist and retired brewer Richard Cox.
- Michael Faraday isolates benzene as Bicarburet of Hydrogen.
- Hans Christian Ørsted reduces aluminium chloride to produce metallic aluminium in an impure form.
- Friedrich Wöhler and Justus von Liebig perform the first confirmed discovery and explanation of isomers, earlier named by Berzelius. Working with cyanic acid and fulminic acid, they correctly deduce that isomerism was caused by differing arrangements of atoms within a molecular structure.
- G. Poulett Scrope publishes Considerations on Volcanoes, the first systematic work on volcanology.
- Augustin-Louis Cauchy presents the Cauchy integral theorem for general integration paths—he assumes the function being integrated has a continuous derivative.
- Augustin-Louis Cauchy introduces the theory of residues in complex analysis.
- Peter Gustav Lejeune Dirichlet and Adrien-Marie Legendre prove Fermat's last theorem for n = 5.
- André-Marie Ampère discovers Stokes' theorem.
- Jean-Baptiste Sarlandière's Mémoires sur L'Électro-Puncture introduces Western medicine to electroacupuncture.
- Georges Cuvier proposes his catastrophe theory as the cause of extinctions of large groups of animals.
- Étienne Geoffroy Saint-Hilaire identifies Cuvier's fossil `crocodile´ as a teleosaurus.
- August – The wire-cable suspension bridge between Tournon-sur-Rhône and Tain-l'Hermitage, designed by Marc Seguin, opens.
- September 27 – The world's longest railway to be worked by steam locomotives at this date, the Stockton and Darlington Railway, opens in northern England.
- October 26 – The Erie Canal officially opens over 363 miles (584 km) from Albany, New York, to Lake Erie.
