But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.

It is one of the simplest examples of a differential equation.

This is an enormous branch of geochemistry called Geochronology.

It is an accurate way to date specific geologic events.

Over time, radioactive isotopes change into stable isotopes by a process known as radioactive decay.

Some radioactive parent isotopes decay almost instantaneously into their stable daughter isotopes; others take billions of years.

In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.

Since there is now only 1/4 of the original amount of Parentium-123, we know that two half-lives of Parentium-123 have elapsed.

We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes.

For example, the element Uranium exists as one of several isotopes, some of which are unstable.

When an unstable Uranium (U) isotope decays, it turns into an isotope of the element Lead (Pb).

Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.

As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.
