The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.Anthropologists can describe a people’s physical character, culture, and environmental and social relations.Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.Historians can tell what cultures thrived in different regions and when they disintegrated.American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.

Relative dating stems from the idea that something is younger or older relative to something else.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.The Mayan calendar used 3114 BC as their reference.More recently is the radiocarbon date of 1950 AD or before present, BP.The Greeks consider the first Olympic Games as the beginning or 776 BC.
