About the Research: Assessing the Two-Pool Decay Model This paper evaluated the two-pool carbon exponential decay model, focusing on parameterizing the C1 and C2 carbon fractions. They conducted a ...

This first calculation goes through 25 runs. Based on the graph, at what time should all the atoms decay? Start with 2,000 atoms. At what time do only 1,000 atoms remain? This is the half-life.

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter ...

Exponential graphs can be used to represent many real-life situations including growth of bacteria, compound interest, radioactive decay, and population increase.
