![]() The technique was developed in the late 1940s at the University of Chicago by chemistry professor Willard Libby, who would later receive the Nobel Prize for the work. Scientists can estimate how long the organism has been dead by counting the remaining carbon-14 atoms. When they die, the carbon-14 starts to change into other atoms over time. It is based on the fact that living organisms-like trees, plants, people, and animals-absorb carbon-14 into their tissue. ![]() The invention of radiocarbon dating elegantly merged chemistry and physics to develop a scientific method that can accurately determine the age of organic materials as old as approximately 60,000 years. What discoveries has carbon-14 testing revealed?. ![]() Has radiocarbon dating improved over the years?. ![]() What are the limitations of carbon-14 dating?. ![]()
