Creation of Ununquadium
(Element 114) was reported by scientists at Dubna (Joint Institute for Nuclear Research) in Russia.
1988 - Klaus Fuchs died.
Department of Energy/Los Alamos National Laboratory
Fuchs was a German physicist who became known as the 'Atom Bomb Spy' when he was convicted of espionage for passing vital information about atomic weapons to the Soviet Union. He was part of the Manhattan project to built the atomic bomb and passed notes along to a Soviet contact and had a significant effect on the Soviet atomic weapons project after the war. He was convicted of espionage and served 9 years of a 14 year sentence.
1986 - Challenger Tragedy
The space shuttle Challenger exploded shortly after liftoff, killing all seven astronauts on board.
1928 - Michael Foster died.
Foster was an English physiologist who introduced modern methods of teaching biology that emphasize training in laboratory. His methods would put Britain on the forefront of physiological studies and research and make physiology a scientific profession.
1922 - Robert W. Holley was born.
Holly was an American biochemist who shares the 1968 Nobel Prize in Medicine with Warren Nirenberg and Har Gobind Khorana for research into how DNA controls synthesis of proteins. He determined the sequence and structure of alanine tRNA, which incorporates the amino acid alanine into proteins. This helped determine the synthesis of proteins from messenger RNA.
1903 - Kathleen Yardley Lonsdale was born.
Lonsdale was a crystallographer who established the chemical structure of benzene. She was also the first woman to become a Fellow of the Royal Society.
1864 - Benoît Émile Clapeyron died.
Clapeyron was a French engineer and physicist whose studies on steam engines and heat of vaporization of fluids led to the Second Law of Thermodynamics. He was the first to graphically illustrate the closed curve processes of a engine cycle on a pressure vs. volume chart. He is also known for his contributions to civil engineering through his work on static mechanics.
