Radiocarbon dating was developed by Willard Libby at the University of Chicago in 1946. The technique measures the ratio of carbon-14 to carbon-12 in a sample to determine its age, giving archaeologists and paleontologists an atomic clock for dating organic specimens. Libby won the 1960 Nobel Prize in Chemistry for this work.

And you know this is a really really important concept. 1946 invention of the radio invention of radiocarbon dating. >> Yes. This is Willard Libby at University of Chicago. He developed the technique of radiocarbon dating using carbon 14. It basically gives us an accurate clock to figure out how old samples are. So whenever we talk about oh like this paleontological or this um anthropological specimen is this many years old. A lot of times what we're doing is we're measuring the amount of carbon 14 there is compared to the
