The year 1913 in science and technology involved some significant events, listed below.

Astronomy

• February 9 – Meteor procession of February 9, 1913 visible along a great circle arc 6,040 miles (9,720 km) across the Americas. Astronomer Clarence Chant concludes that the source was a small, short-lived natural satellite of the Earth.^[1][2]

Chemistry

• February – Daniel J. O'Conor and Herbert A. Faber file for a United States patent on the composite plastic laminate Formica.^[3]
• Protactinium is first identified by Kasimir Fajans and O. H. Göhring.
• Henry Moseley shows that nuclear charge is the real basis for numbering the elements and discovers a systematic relation between wavelength and atomic number by using x-ray spectra obtained by diffraction in crystals.^[4] Frederick Soddy proposes that isotopes (a term which he introduces) may have differing atomic weights.^[5]
• J. J. Thomson shows that charged subatomic particles can be separated by their mass-to-charge ratio, the technique known as mass spectrometry.^[6]

Geology

• Albert A. Michelson measures tides in the solid body of the Earth

History of science

• Pierre Duhem begins publication of Le Système du Monde: Histoire des Doctrines cosmologiques de Platon à Copernic in Paris.

Mathematics

• Publication of the 3rd volume of Principia Mathematica by Alfred North Whitehead and Bertrand Russell, one of the most important and seminal works in mathematical logic and philosophy.
• Émile Borel first states the infinite monkey theorem in the way it will subsequently become known.^[7]

Medicine

• Nikolay Anichkov first demonstrates the significance and role of cholesterol in atherosclerosis pathogenesis.^[8]
• Albert Schweitzer sets up the Albert Schweitzer Hospital at Lambaréné in French Equatorial Africa.

Physics

• William Henry Bragg and William Lawrence Bragg work out the Bragg condition for strong X-ray reflection.
• Niels Bohr presents his quantum model of the atom.^[9][10][11]
• Robert Millikan measures the fundamental unit of electric charge.
• Georges Sagnac demonstrates the Sagnac effect, showing that light propagates at a speed independent of the speed of its source.^[12][13][14]
• Johannes Stark demonstrates that strong electric fields will split the Balmer spectral line series of hydrogen.

Psychology

• John B. Watson publishes the article "Psychology as the Behaviorist Views It" — sometimes called "The Behaviorist Manifesto".^[15]

Technology

• April 29 – Swedish American engineer Gideon Sundback of Hoboken, New Jersey, patents the all-purpose zipper.
• May 26 (May 13 O.S.) – Igor Sikorsky flies the world's first 4-engine fixed-wing aircraft, his Bolshoi Baltisky biplane, near Saint Petersburg.^[16][17]
• August – Invention of stainless steel by Harry Brearley in Sheffield, England (concurrent with the invention of another type in the United States by Elwood Haynes).^[18]
• French inventor René Lorin patents the ramjet, but attempts to build a prototype fail due to inadequate materials.^[19]

Publications

• Die Naturwissenschaften first published by Die Kaiser-Wilhelm-Gesellschaft zur Förderung der Wissenschaften e. V.
• Journal of Ecology first published.
