Libby's system uses chemical analysis to determine the age of organic materials based on carbon-14 content.

He did this largely on his own over a period of many years, many trials and tribulations.

First tested and calibrated with material found in 4,000-year-old Egyptian tombs, carbon-dating has been used on progressively older and older relics, and has become an extremely important tool for anthropologists, archaeologists, geologists, and other earth scientists.

Carbon-14 dating is now believed to be accurate for finding the age of materials up to 70,000 years old, with a margin of error of about ten percent.

this discovery was certainly of nobel caliber, ruben’s death in 1943 from an accident involving phosgene precluded a joint award to him and kamen, because nobel prizes are not awarded posthumously.

using this mathematical calculation, libby proposed that he could determine the age of organisms that had died as many as 30,000 years ago.
