They proved this by showing that C-14 dates of wooden artifacts with cartouches (dated royal names) did not agree.

When it comes to dating archaeological samples, several timescale problems arise.

The object's approximate age can then be figured out using the known rate of decay of the isotope.

This has to do with figuring out the age of ancient things.

If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.

Other isotopes are used by geologists to date older material.

Each radiocarbon date has a statistical probability shown by the ± number.

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.

A useful application of half-lives is radioactive dating.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).

The Greeks consider the first Olympic Games as the beginning or 776 BC.

is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.
