These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages. Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others Whereas Lanphere and his colleagues referred to these two K-Ar ages of and million years, the ages are actually from another report and were obtained from samples collected at two localities in Canada, not Alaska. There is nothing wrong with these ages; they are consistent with the known geologic relations and represent the crystallization ages of the Canadian samples. The Liberian example Table 2 is from a report by Dalrymple and others

In one case, a modified Drake Equation was used to estimate the probable number of eligible mates, period. This application differs from determining the probable number of eligible mates who satisfy a select number of criterion. For example, the number of eligible woman is different from the number of eligible women who, say, like Star Trek.
A western rule-of-thumb is to take your age, divide it by two, and add seven to that (you 2 + 7). This finds the youngest age of a person you can have a romantic relationship with while keeping your relationship socially acceptable.

Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. 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.
A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable.

Abstract Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches.
Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results. In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that aboveground testing of nuclear weapons during the cold war — caused an extreme increase in global levels of carbon 14C , which has been carefully recorded over time.
Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Radiocarbon analysis showed an excellent precision with an overall absolute error of 1. Aspartic acid racemization also showed a good precision with an overall absolute error of 5.

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4.

What Does Age Appropriate Dating Mean?
Radiometric dating is a means of determining the “age” of a mineral specimen by determining the relative amounts present of certain radioactive elements. By “age” we mean the elapsed time from when the mineral specimen was formed. Radioactive elements “decay” that is, change into other elements by “half lives. The formula for the fraction remaining is one-half raised to the power given by the number of years divided by the half-life in other words raised to a power equal to the number of half-lives.
To determine the fraction still remaining, we must know both the amount now present and also the amount present when the mineral was formed. Contrary to creationist claims, it is possible to make that determination, as the following will explain:
The Dating Equation: ½(your age) + 7. October 4, By Dr. Benjamin Le 3 Comments. Tweet. Share Pin +1. 30 Shares. A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years.
Dating Methods using Radioactive Isotopes Oliver Seely Radiocarbon method The age of ancient artifacts which contain carbon can be determined by a method known as radiocarbon dating. This method is sometimes called C or carbon dating. Carbon is formed in the upper atmosphere by the bombardment of nitrogen by cosmic rays. Cosmic rays are protons, particles and some heavier ions. Other particles, including neutrons, are produced by subsequent collisions.
The collision of a neutron with the nucleus of a N isotope produces C , as follows: This form of carbon is radioactive. That is, it decays spontaneously to nitrogen 14 by a path involving the emission of a high energy electron a beta particle:

The DATE formula is typically used to construct a date by providing the constituting parts such as day, month and year. The minimum and maximum values that a date can take is Office is January 1, and December 31, if that existed. DATE year, month, day year year is the year in which the date would be occurring.
An interesting fun dating age range calculator to find out minimum and maximum dating age of person whom you wish to date. As per “Half Your Age Plus 7” relationship rule, the age of the younger person you date should not be less than half the age of the older person plus 7 years; and the age of the older person you date should not be more than your age minus 7 and doubled it.
Carbon Dating Most everyone has heard of Carbon dating on the news or elsewhere sometime in the past years. In this article I hope to explain the theoretical and physical science behind Carbon dating, and discuss how it affects our lives and the validity of the process. Scientists use Carbon dating for telling the age of an old object, whose origin and age cannot be determined exactly by normal means. Because of this method Chemistry has become intertwined with History, Archeology, Anthropology, and Geology.
Poole Many items that have been thought to come from one time have been tested and found out to actually come from a few thousands years beforehand. Places where historians believed that human civilization came to exit say, only 2, years ago, have actually been proven to have had some form of human civilization more than 4, years ago. Poole Fine art collectors have used Carbon dating to determine if a piece of antique art is actually genuine.
