Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: in , he won a Nobel Prize in Chemistry for the invention. It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.

This discrepancy, often called the de Vries effect, was resolved by the study of tree rings. Two different trends can be seen in the tree ring series.
With an accout for my. Radiocarbon dating is a radiometric dating method that uses the naturally occurring isotope carbon 14 C to determine the age of carbonaceous materials up to about 60, years. Such raw ages can be calibrated to give calendar dates.
