Beyond the specific topic of natural 14 C, it is hoped that this account may serve as a metaphor for young scientists, illustrating that just when a scientific discipline may appear to be approaching maturity, unanticipated metrological advances in their own chosen fields, and unanticipated anthropogenic or natural chemical events in the environment, can spawn new areas of research having exciting theoretical and practical implications. Carbon and other radioisotopes are used to measure the age of fossils, rocks, and other materials that make up Earth's geologic history. Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed.
Uses of Radiocarbon Dating Climate science required the invention and mastery of many difficult techniques. In , Willard Libby proposed carbon dating, a method for dating carbon- containing objects (like wood, leather, or cloth) that exploits the.
