Willard f. libby: father of the radiocarbon revolution (renfrew, 1973, winner of the nobel prize in 1960. Carbon 14 dating works: everything is made of atoms, atoms have a very dense portion called a nucleus. Inside the nucleus there are two types of particles: protons (+) and neutrons (=: protons and neutrons way the same. Isotopes: atoms that have the same number of protons (i. e. , belong to the same element) but different numbers of neutrons (i. e. , different weights). Another way of saying this is exponential decay . = *we are dating the date of death . Radiometric dating techniques: carbon 14 (14c): half life is 5730 years, can date anything organic that is ~1000 years old to ~50,000 years old (absolute max. The stuff of evolutionary anthropology and archaeology: artifacts: objects or materials made or modified for use by hominins. e. g.
