    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 the only way Parentium-123 decays, and there is no other source of Daughterium-123.

    This is consistent with the assumption that each decay event is independent and its chance does not vary over time.

    where is the half-life of the element, is the time expired since the sample contained the initial number atoms of the nuclide, and is the remaining amount of the nuclide.

    The key is to measure an isotope that has had time to decay a measurable amount, but not so much as to only leave a trace remaining.

    Given isotopes are useful for dating over a range from a fraction of their half life to about four or five times their half life.
