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).
• 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.

Chemistry

• Kikunae Ikeda discovers monosodium glutamate, the chemical behind the taste of umami.
• 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. proposes that genetic defects cause many inherited diseases.

History of science

• National Technical Museum (Prague) founded.

Mathematics

• Ernst Zermelo axiomizes set theory, thus avoiding Cantor's contradictions.
