The year 1912 in science and technology involved some significant events, listed below.
- At the beginning of this year an extreme decadal variation in length of day produces mean solar days having a duration of 86400.00389 seconds of Terrestrial Time (or ephemeris time), the slowest rotation of Earth's crust ever to be recorded.
- Peter Debye derives the T-cubed law for the low temperature heat capacity of a nonmetallic solid.
- Casimir Funk introduces the concept of vitamins.
- Frans, a German chemist working for Griesheim-Elektron, patents a means of producing vinyl chloride from acetylene and hydrogen chloride using mercuric chloride as a catalyst.
- Fritz Klatte discovers polyvinyl acetate, and applies for a patent for its preparation from acetylene gas although it is not successfully commercialized at this time.
- Wilbur Scoville devises the Scoville scale for measuring the heat of peppers.
- December 24 – Merck files patent applications for synthesis of the entactogenic drug MDMA, developed by Anton Köllisch.
- January – Alfred Wegener proposes a fully formulated theory of continental drift.

- —Visitas Gratuitas

History of science
- Isis, the journal of the history of science, is founded in Ghent by George Sarton.
- Georgius Agricola's De re metallica (1556) is first published in an English translation, made by Herbert and Lou Henry Hoover, in London.
- Voynich manuscript discovered.
- Publication of the 2nd volume of Principia Mathematica by Alfred North Whitehead and Bertrand Russell, one of the most important and seminal works in mathematical logic and philosophy.
