No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.Digital technology and smartphones in particular have transformed many aspects of our society, including how people seek out and establish romantic relationships.Few Americans had online dating experience when Pew Research Center first polled on the activity in 2005, but today 15% of U. adults report they have used online dating sites or mobile dating apps.
