    Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

    The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
