Concept
1910 in science
Summary
The year 1910 in science and technology involved some significant events, listed below.
January 12 – Great January Comet of 1910 first observed (perihelion: January 17).
January 22 – At 9:30 in the evening, the Vigarano Meteorite splits as it falls to Earth in Italy at the locality of the same name, near Emilia. Weighing 11.5 kg (or 25 lb.), the stone that is recovered is the first of the CV chondrites named for the location. CV chondrites are described as the oldest rocks in the solar system. The other piece of the meteorite, weighing , is found a month later.
April 10 – Halley's Comet becomes visible with the naked eye (perihelion: April 20); Earth passes through its tail about May 19 (its next visit will be in 1986).
December 30 – A nova (later referred to as DI Lacertae), is spotted in the constellation Lacerta, by Anglican minister and astronomer T. H. E. C. Espin, making him the first human to see the birth of the new star.
Approximate date – The Hertzsprung–Russell diagram is developed by Ejnar Hertzsprung and Henry Norris Russell.
Behrmann projection introduced.
Albert Einstein and Marian Smoluchowski find the Einstein-Smoluchowski formula for the attenuation coefficient due to density fluctuations in a gas.
Umetaro Suzuki isolates the first vitamin complex, aberic acid.
Hoechst AG market Arsphenamine under the trade name Salvarsan, the first organic antisyphilitic, its properties having been discovered the previous fall by bacteriologist Sahachiro Hata during systematic testing in the laboratory of Paul Ehrlich; it rapidly becomes the world's most widely prescribed drug.
George Barger and James Ewens of Wellcome Laboratories in London first synthesize dopamine.
Frederick Soddy shows that the radioelements mesothorium (later shown to be 228Ra), radium (226Ra, the longest-lived isotope), and thorium X (224Ra) are impossible to separate, leading to the identification of isotopes.
Publication of the 1st volume of Principia Mathematica by Alfred North Whitehead and Bertrand Russell, one of the most important and seminal works in mathematical logic and philosophy.
