Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.
Given isotopes are useful for dating over a range from a fraction of their half life to about four or five times their half life.ARGUMENTS against the historical authenticity of the book of Genesis appear with increasing frequency. Common usage often makes no distinction between the terms radiocarbon date and radiocarbon age.Because radiocarbon dating is used in many of these arguments, those who are endeavoring to proclaim the everlasting gospel depicted in Revelation 14: 6-12 should understand this dating technique. The greater the ratio, the more recent the specimen; the smaller the ratio, the older the specimen. A radiocarbon age is the usual way of reporting a measurement of the relative amount of radioactive carbon (carbon with isotope weight 14) in a specimen with a chemical composition that includes carbon.For example Carbon 14 has a half life of 5,730 years.If a sample has 6.25 % of the amount of Carbon 14 present in a living sample then four half lives have passed since the sample died and stopped absorbing Carbon. Carbon 14 has a limited of approximately 50,000 years or less.
