Brief history of carbon dating

Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.CT exams are now quicker and more patient-friendly than ever before.

During its 25-year history, CT has made great improvements in speed, patient comfort, and resolution.

Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.
