In 1946, Willard Libby proposed a forward thinking way of dating natural materials by calculating their content of carbon-14, a newly found radioactive isotope of carbon. Referred to as radiocarbon relationship, this technique provides objective age estimates for carbon-based objects that comes from residing organisms. The вЂњradiocarbon revolutionвЂќ made possible by LibbyвЂ™s development greatly benefitted the fields of archaeology and geology by permitting practitioners to build up more exact chronologies that are historical geography and cultures.
Willard Libby’s notion of radiocarbon dating
Willard Libby (1908вЂ“1980), a professor of chemistry in the University of Chicago, started the extensive research that led him to radiocarbon relationship in 1945. He had been influenced by physicist Serge Korff (1906вЂ“1989) of New York University, whom in 1939 found that neutrons had been produced throughout the bombardment associated with environment by cosmic rays.
