Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.

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

In calculus terms, we write: d N(t)/dt = -K * N(t) or d N(t)/N(t) = -K dt The minus sign means that each decay decreases the total number of atoms.

Integrating both sides, we get: ln N(t) = -Kt C C is the constant of integration that we can often ignore, but not here.

When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.

Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

Others measure the subatomic particles that are emitted as an isotope decays.

Some measure the decay of isotopes more indirectly.

They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.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.Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.Each isotope is identified with what is called a ‘mass number’.

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

The gap in between offered Nick the opportunity to come home, if all goes as planned. If it all goes well, hell take the 20 hour flight home beginning Thursday our time and arriving sometime Friday afternoon.
