Since its invention in 1947, carbon dating has revolutionised many fields of science by allowing scientists to estimate the age of an organic material based on how much carbon-14 it contains. However, ...

Potassium-argon dating of igneous and metamorphic rocks with applications to the basin ranges of Arizona and Sonora / P.E. Damon -- A comparison of the isotopic mineral age variations and petrologic ...

Geologists have calculated the age of Earth at 4.6 billion years. But for humans whose life span rarely reaches more than 100 years, how can we be so sure of that ancient date? It turns out the ...

Okay so I understand at a very basic level how radiometric dating works, but I have a question. How do scientists know the half-life of isotopes, when some of them are measured in millions or billions ...
