Learn about the history of science by reading about the significant scientific events that took place on this day in history.

1994 - First atoms of element 110 produced.

Scientists at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany detected the evidence of four atoms of element 110. They were produced by bombarding lead with nickel ions. After the IUPAC recognized their discovery, they named the element darmstadtium.

1952 - Jack Szostak was born.

Szostak is a British biologist who shares the 2009 Nobel Prize in Medicine with Elizabeth Blackburn and Carol W. Greider, for the discovery of how chromosomes are protected by telomeres. A telomere is a section of DNA at the end of a chromosome. He also helped clarify chromosomal recombination during meiosis.

1952 - Chaim Azriel Weizmann died.

Weizmann was a Russian chemist who developed the method to produce acetone using bacteria and fermentation during World War I. Acetone was vital to the production of cordite and explosives for the war effort. After the War, he modified his technique to produce other organic compounds using bacteria during fermentation. He was also a instrumental in the formation of the State of Israel and served as their first President.

1934 - Carl Sagan was born.

Sagan was an American astronomer who popularized astronomy and astrophysics through a successful 13 part television program called "Cosmos: A Personal Voyage". He also supported efforts to search for evidence of extra-terrestrial life and the SETI (Search for Extra-Terrestrial Intelligence) program. He was among the first to recognize Saturn's moon, Titan could support oceans that could support life and the surface of Venus was more likely to be extremely hot and dry rather than stormy.

1897 - Ronald George Wreyford Norrish was born.

Norrish was an English chemist who shares half the 1967 Nobel Prize in Chemistry with George Porter for their research into very fast chemical reactions. They used pulses of light to disrupt organic compounds at equilibrium to increase the number of free radicals. A second pulse of light would record the changes before equilibrium is re-established to determine the intermediate steps to perform these reactions.

1864 - Dmitry Iosifovich Ivanovsky was born.

Ivanovsky was a Russian microbiologist who was the first to discover viruses. He was studying the mosaic disease of tobacco and found microscopic organisms he believed to be bacteria. Viruses would be independently discovered a few years later by Dutch botanist M.W. Beijerinck, but credit for the discovery was given to Ivanovsky.
