[edit] Exploration
- The Austro-Hungarian North Pole Expedition discovers Franz-Josef Land.
[edit] Mathematics
- Charles Hermite proves that the mathematical constant e is a transcendental number.[1]
- Henri Brocard introduces the Brocard points, Brocard triangle and Brocard circle.[2][1][3]
[edit] Meteorology
- September - Agreement for establishment of International Meteorological Organization.
[edit] Physics
- June 14 - Johannes Diderik van der Waals defends his thesis, Over de Continuiteit van den Gas en Vloeistoftoestand ("On the continuity of the gaseous and liquid state") at Leiden University. In this, he introduces the concepts of molecular volume and molecular attraction; gives a semi-quantitative description of the phenomena of condensation and critical temperatures; and derives the van der Waals equation.[4]
- September 22 - James Clerk Maxwell delivers a discourse on molecules to the British Association for the Advancement of Science meeting in Bradford.[5]
- Frederick Guthrie is the first to report observing thermionic emission.[6]
[edit] Technology

- Carl von Linde installs his first commercial refrigeration system, built by Maschinenfabrik Augsburg for the Spaten Brewery and using dimethyl ether as the refrigerant.
- Christopher Miner Spencer introduces the fully automatic turret lathe.[7]
