1908 in science
| |||
|---|---|---|---|
The year 1908 in science and technology involved some significant events, listed below.
Archaeology
- A 40,000-year-old Neanderthal boy skeleton is found at Le Moustier in southwest France by Otto Hauser.
Astronomy
- If its start and end are defined using mean solar time then due to the extreme length of day variation this is the longest year of the Julian calendar or Gregorian calendar, having a duration of 31622401.38 seconds of Terrestrial Time (or ephemeris time).[1]
- June 30 [O.S. June 17 ] – Tunguska event in Siberia, an explosion believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 mi) above the Earth's surface.[2][3][4]
Chemistry
- Kikunae Ikeda discovers monosodium glutamate, the chemical behind the taste of umami.[5]
- Heike Kamerlingh Onnes liquefies helium.
Genetics
- G. H. Hardy and Wilhelm Weinberg independently formulate the Hardy–Weinberg principle which states that both allele and genotype frequencies in a population remain in equilibrium unless disturbed.[6]
History of science
- Site of Ulugh Beg Observatory located in Samarkand by Russian archaeologist V. L. Vyatkin.
- National Technical Museum (Prague) founded.
Mathematics
- Ernst Zermelo axiomizes set theory, thus avoiding Cantor's contradictions.
- Josip Plemelj solves the Riemann problem about the existence of a differential equation with a given monodromic group and uses Sokhotsky-Plemelj formulae.
- Student's t-distribution published by William Sealy Gosset (anonymously).[7]
Physics
- Hans Geiger and Ernest Rutherford invent the Geiger counter.
- Gustav Mie publishes the Mie solution to Maxwell's equations on the scattering of electromagnetic radiation by a sphere.[8]
Physiology and medicine
- April 27 – First Congress for Freudian Psychology, held in Salzburg.
- Swiss psychiatrist Eugen Bleuler introduces the term schizophrenia.[9]
- Austrian American pathologist Leo Buerger gives the first accurate pathological description of Thromboangiitis obliterans ("Buerger's disease") at Mount Sinai Hospital (Manhattan).[10]
- Victor Horsley and R. Clarke invents the stereotactic method.
- Margaret Reed Lewis, working in Berlin, becomes probably the first person successfully to grow mammalian tissue in vitro.[11]
Technology
- A long-distance radio message is sent from the Eiffel Tower for the first time.
- Henry Ford develops the assembly line method of automobile manufacturing and produces the first Model T automobile.
