{{Year nav topic5|1946|science}}The year 1946 in science and technology involved some significant events, listed below. Astronomy- January 10 – The United States Army Signal Corps' Project Diana bounces radar waves off the Moon.
- Reginald Aldworth Daly of Harvard University first proposes a giant impact hypothesis to account for formation of the moon.[1]
Biology- November 10 – Peter Scott opens the Slimbridge Wetland Reserve in England.
- Karl von Frisch publishes "Die Tänze der Bienen" ("The dances of the bees").[2]
- Edmund Jaeger discovers and later documents, in The Condor,[3] a state of extended torpor, approaching hibernation, in a bird, the common poorwill.[4]
Cartography- The Chamberlin trimetric projection is developed in 1946 by Wellman Chamberlin for the National Geographic Society.[5]
Computer science- February 14–15 – ENIAC, the first non-classified all-electronic Turing complete computer, built under the direction of J. Presper Eckert and John Mauchly, is announced and dedicated at the University of Pennsylvania's Moore School of Electrical Engineering.[6] It is programmable by plugboard and uses conditional branching.
- December 11 – Frederick Williams receives a patent for a random-access memory device.[7]
Earth sciences- Arthur Holmes estimates the age of the Earth, using uranium–lead dating.
Medicine- July 14 – Dr. Benjamin Spock's The Common Sense Book of Baby and Child Care is first published in New York; it becomes one of the biggest best-sellers of all time.[8]
- Harold Gillies begins to perform sex reassignment surgery on Michael Dillon, including the first female-to-male transsexual phalloplasty.[9]
- Chance Brothers of Smethwick, England, produce the first all-glass syringe with interchangeable barrel and plunger, allowing easy mass-sterilisation of components.
- Alfred Gilman, with Frederick S. Philips, first publish the results of trials of anti-cancer chemotherapy, using mechlorethamine, carried out with Louis S. Goodman.[10][11]
Physics- January 1 – Atomic Energy Research Establishment established at Harwell, Oxfordshire under John Cockcroft.
- May 21 – Manhattan Project physicist Louis Slotin accidentally triggers a fission reaction at the Los Alamos National Laboratory and gives himself a lethal dose of hard radiation, making him the second victim of a criticality accident in history.
- The BBGKY hierarchy of equations for s-particle distribution functions is applied to the derivation of kinetic equations by Nikolay Bogolyubov in a paper received in July 1945 and published in 1946 in Russian[12] and in English.[13] The related kinetic transport theory is considered by John Gamble Kirkwood in a paper[14] received in October 1945 and published in March 1946. The first paper by Max Born and Herbert S. Green considering a general kinetic theory of liquids is received in February 1946 and published on 31 December 1946.[15]
