The year 1922 in science and technology involved some significant events, listed below.
Archaeology
November 4 – British archaeologist Howard Carter and his men find the entrance to King Tutankhamen's tomb in the Valley of the Kings of Egypt.
Biology
August – The California grizzly bear is hunted to extinction. Last known wild Barbary lion (P. l. leo) shot in the Atlas Mountains of Morocco. The Amur tiger becomes extinct in South Korea. H. J. Muller sets out the basic properties of genetic heredity.
Chemistry
June 20 – Degesch applies to patent the cyanide-based insecticide Zyklon B (credited to Walter Heerdt) in Germany. Vitamin E is discovered by Herbert McLean Evans and Katharine Scott Bishop at the University of California, Berkeley and Vitamin D by Elmer McCollum and others. Czech chemist Jaroslav Heyrovský invents polarographic methods of chemical analysis. German chemist Hermann Staudinger proposes what he will come to call macromolecules.
Ethnology
Bronisław Malinowski's influential ethnological text Argonauts of the Western Pacific is published.
Mathematics
First publication of Ludwig Wittgenstein's Tractatus Logico-Philosophicus in an English translation. Jarl Waldemar Lindeberg provides a proof of the "Lindeberg condition" of the central limit theorem. Ernst Steinitz proves Steinitz's theorem in polyhedral combinatorics.
Medicine
January 11 – First successful insulin treatment of diabetes, by Frederick Banting in Toronto, using a pure preparation intravenously injected; on the same date Nicolae Paulescu makes an apparently successful rectal administration of an insulin preparation.
Meteorology
English mathematical physicist Lewis Fry Richardson proposes a scheme for weather forecasting by solution of differential equations, the method used in modern times, in his work Weather Prediction by Numerical Process.
Paleontology
First of four successive American Museum of Natural History expeditions to Mongolia under Roy Chapman Andrews which will discover fossils of Indricotherium (a gigantic hornless rhinoceros then named "Baluchitherium"), Protoceratops, a nest of Protoceratops eggs (found in 1995 to be from Oviraptor), Pinacosaurus, Saurornithoides, Oviraptor and Velociraptor, none of which were known before.
Physics
Arthur Compton studies X-ray photon scattering by electrons. Otto Stern and Walther Gerlach show "space quantization". Hilding Faxén introduces Faxén's law for the velocity of a sphere in fluid dynamics. Albert Einstein's The Meaning of Relativity: Four Lectures Delivered at Princeton University, May 1921 is published by Princeton University Press.
Technology
February 14 – The world's first regular wireless broadcasts for entertainment, made by Peter Eckersley, begin transmission on radio station 2MT from a hut at the Marconi Company laboratories at Writtle near Chelmsford in England. This is followed in the United Kingdom on May 11 by station 2LO from Marconi House in London, which from November 22 becomes the British Broadcasting Company (BBC). Lancia Lambda is the first automobile to use monocoque construction. Approximate date – Madeleine Vionnet introduces the bias cut dress in Paris.
