Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.The passage of time can be charted by the reduction in the number of parent atoms, and the increase in the number of daughter atoms.Radiometric dating can be compared to an hourglass.Most of the elements in nature are stable and do not change.However, some elements are not completely stable in their natural state.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

Most processes that we are familiar with are like sand in an hourglass.

In exponential decay the amount of material decreases by half during each half-life.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

You cannot predict exactly when any one particular grain will get to the bottom, but you can predict from one time to the next how long the whole pile of sand takes to fall.
