1924 in science

The year 1924 in science and technology involved some significant events, listed below.


Astronomy and space exploration

  • November 23 – Edwin Hubble announces his discovery that Andromeda, previously believed to be a nebula, is actually another galaxy, and that the Milky Way is only one of many such galaxies in the universe.
  • The Einstein Tower near Potsdam, Germany, designed by Erich Mendelsohn, becomes operational as an astrophysical observatory.
  • 1056 Azalea is discovered.
  • Biology

  • The term "ectogenesis" is coined by British scientist J.B.S. Haldane to describe the growth of mammalian embryos in artificial environments.
  • Biochemistry

  • The first inactive tetanus toxoid is discovered and produced.
  • History of science and technology

  • December 17 – Dismantling of James Watt's workshop for display in the Science Museum, London, commences.
  • Mathematics

  • David Hilbert proposes Hilbert's paradox of the Grand Hotel.
  • Medicine

  • German physiologist and psychiatrist Hans Berger records the first human electroencephalogram.
  • Paleontology

  • The first specimen of Australopithecus africanus, the fossil skull of the "Taung Child", is identified in South Africa.
  • Physics

  • S. N. Bose and Albert Einstein publish papers in Zeitschrift für Physik applying Bose–Einstein statistics to light quanta and to atomic models and predicting existence of the Bose–Einstein condensate.
  • E. C. Stoner publishes a paper pointing out that for a given value of the principal quantum number (n), the number of energy levels of a single electron in the alkali metal spectra in an external magnetic field, where all degenerate energy levels are separated, is equal to the number of electrons in the closed shell of the rare gases for the same value of n. This leads to discovery of the Pauli exclusion principle.
  • Louis de Broglie introduces the wave-model of atomic structure, based on the ideas of wave–particle duality.
  • Technology

  • February 5 – Hourly time signals from Royal Greenwich Observatory are broadcast for the first time.
  • February – John Logie Baird sends rudimentary television pictures over a short distance.
  • Václav Holek designs the ZB vz. 26 light machine gun for Zbrojovka Brno.
  • Awards

  • Nobel Prizes
  • Physics: Karl Manne Georg Siegbahn
  • Medicine: Willem Einthoven
  • Births

  • March 11 – Franco Basaglia, Italian psychiatrist (died 1980)
  • March 23 – Bjørn G. Andersen, Norwegian quaternary geologist and glaciologist (early environmental studies) (died 2012)
  • June 24 – James W. Black, Scottish pharmacologist (Nobel Prize in Physiology or Medicine, 1988) (died 2010)
  • August 1 – John Clive Ward, English-born physicist working in quantum electrodynamics (died 2000)
  • November 9 – Don Beaven, New Zealand medical researcher in the area of diabetes treatment and prevention (died 2009)
