Willard Libby

Willard Frank Libby (Willard Frank Libby, December 17, 1908 September 8th 1980), a famous American chemist, winner of the 1960 Nobel prize in chemistry, graduated from famous universities in the USA. UC Berkeley (undergraduate and Ph.D.) .
Willard Libby
Libby devoted his life to Radiocarbon dating method (radiocarbon dating) the development of the invention 14s - Determination of carbon And this method is widely used in archaeology, geology, geophysics and other disciplines, so in 1960 (when he was awarded the Nobel prize for Chemistry University of Chicago Professor) . Libby has taught at UC Berkeley , University of Chicago as well as University of California at Los Angeles .

Willard Libby Life

Grand Valley Libby was born in Colorado, he was UC Berkeley (UC Berkeley) obtained a Bachelor of Science degree and a PhD in Chemistry (1931) (1933), to become the university lecturer, and later became the assistant professor, vice . In 1930s Libby built a Geiger counter to measure the natural and man-made weak radiation. In 1941, he joined the Berkeley branch of the American Chemical Society .
Libby won a Guggenheim Fellowship (Guggenheim Fellowship) in 1941, he spent most of the time in Princeton University. The two World War broke out, he and Nobel prize winner, Berkeley Alumnus Harold Clayton Yuri They join in Manhattan Project To make an atomic bomb, responsible for research using gas diffusion method for separation and concentration of uranium isotopes of uranium Hiroshima atomic bomb -235 . After the end of World War II, in 1945, he became University of Chicago The professor In 1954; he was appointed as a member of the U.S. Atomic Energy Commission . In 1959, he became University of California at Los Angeles (UCLA) Professor of chemistry, until his retirement in 1976. .

Willard Libby contribution

 One of the time's person of the year (Willard Libby) One of the time's person of the year (Willard Libby)
The scope of his exploration in the field of scientific research is extremely wide, has a profound basic knowledge of Radiology, nuclear physics, geochemistry and Geophysics, chemistry, earth science knowledge is also very extensive.
Libby is the first human created the unique timing tool -- archaeology clock; in 1960, he won the Nobel prize in Chemistry . Libby concluded, the birth of a new carbon 14 will soon become oxidized, carbon dioxide in atmospheric circulation. The plants absorb carbon dioxide, carbon storage in the plant will be 14; when the plants died after storage in plant carbon 14 will according to the law of radioactive decay and decreased with the prolonging of time, so that it will record the experience from death to measure time . In 1951, he published "determine" Radiocarbon papers He and his own research, widely used in the field of scientific research, help archaeologists to identify sites in the deposition rate help geologists determine the formation of the era, the tectonic movement rate, glacier history, ancient sea plane, ancient coastline changes, the volcano age and sediment; help geography natural environment evolution in ancient history, climate change, soil development history, soil samples from the moon on the back of help . Because he invented the radioactive carbon dating, dating back more than three to fifty thousand years ago, the humanity and the nature of the events in the 1980s, so his invention has very important significance .
