Geologist Ralph Harvey and historian Mott Greene explain the principles of radiometric dating and its application in determining the age of Earth.

As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.

This has to do with figuring out the age of ancient things.

If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.

It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.
