The method of calculating radiometric dates is like using an hourglass.

You can use the hourglass to tell time if you know several things: the amount of sand in the top of the hourglass when it started flowing, the rate that the sand flows through the hole in the middle, and that the quantity of sand in each chamber has not been tampered with.

It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.

The dates must be inferred based on assumptions about the ratios.

The starting isotope is called the parent and the end-product is called the daughter.

The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.

The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.There are three main assumptions that must be made to accept radiometric dating methods.
