1911 in science

The year 1911 in science and technology involved some significant events, listed below.

Astronomy and space science

• June 28 – The Nakhla meteorite (from Mars) lands in the area of Alexandria, Egypt, purportedly killing a dog.^[1]

Conservation

• May 19 – Parks Canada, the world's first national park service, is established as the Dominion Parks Branch under the Department of the Interior.

Earth sciences

• January 3 – 1911 Kebin earthquake: An earthquake of 7.7 moment magnitude strikes near Almaty in Russian Turkestan.^[2]

Exploration

• December 14 – Norwegian explorer Roald Amundsen and a team of four become the first people to reach the South Pole.

Mathematics

• Robert Remak's doctoral dissertation Über die Zerlegung der endlichen Gruppen in indirekte unzerlegbare Faktoren establishes that any two decompositions of a finite group into a direct product are related by a central automorphism.

Medicine

• Eugen Bleuler expands on his definition of schizophrenia as a condition distinct from Dementia praecox, in Dementia Praecox oder Gruppe der Schizophrenien.^[3][4][5]

Physics

• April 8 – Heike Kamerlingh Onnes discovers the phenonomena of superconductivity.^[6]
• June 24–30 – Domenico Pacini runs a series of measurements of underwater ionization in the Gulf of Genoa, demonstrating that the radiation later recognised as cosmic rays cannot be originated by the Earth's crust.
• October – The first Solvay Congress of physicists convenes.
• Ernest Rutherford explains the Geiger–Marsden experiment and derives the Rutherford cross section by deducing the existence of a compact atomic nucleus from scattering experiments. He proposes the Rutherford model of the atom and demonstrates that J. J. Thomson's plum pudding model is incorrect.
• Charles Wilson finishes a sophisticated cloud chamber.

Psychology

• The Ponzo illusion, a geometrical-optical illusion, is first demonstrated by Italian psychologist Mario Ponzo.^[7]

Technology

• January 18 – Eugene Ely lands on the deck of the USS Pennsylvania anchored in San Francisco Bay, the first aircraft landing on a ship.
• June 5 – Charles F. Kettering files a United States patent for an electric starter motor.^[8]
• November 4 – MS Selandia, the first large ocean-going diesel ship, is launched in Denmark; Ivar Knudsen is the diesel engineer. The 1909-launched Dutch diesel tanker Vulcanus also enters service this year.
• John Joseph Rawlings files a United Kingdom patent for a wall plug.^[9]
• The Lewis automatic light machine gun is invented by United States Army Colonel Isaac Newton Lewis, based on initial work by Samuel Maclean.^[10]

Other events

• March–May – A serialized version of Frederick Winslow Taylor's monograph, The Principles of Scientific Management appears in The American Magazine, boosting the efficiency movement.
