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.The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Libby received the Nobel Prize in Chemistry for his work in 1960.

Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact’s age.

And if the artifact is organic, like wood or bone, researchers can turn to a method called radiocarbon dating.
