Discovery of radioactive dating
In 1957, he joined Brandeis University Waltham, MA, USA, and in 1961 he joined the University of California, San Diego, USA, where he remained until his retirement in 1978.Martin Kamen died on August 31, 2002 in in Montecito, CA.Before more precise absolute dating tools were possible, researchers used a variety of comparative approaches called relative dating.These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Think of it as ordering rather than dating.
For this discovery, Libby was awarded the 1960 Nobel Prize in Chemistry. He stayed at UC Berkeley, working on chemistry, nuclear physics, and the elucidation of biochemical reation pathways under Ernest O. Their experiments using born in Toronto, Canada, in 1913, studied chemistry at the University of Chicago, IL, USA, where he received his Ph. Kamen was assigned to the Manhattan Project in 1943, working at Oak Ridge Laboratory, TN.Sometimes only one method is possible, reducing the confidence researchers have in the results. “They’re based on ‘it’s that old because I say so,’ a popular approach by some of my older colleagues,” says Shea, laughing, “though I find I like it myself as I get more gray hair.” Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts.
