What is radiometric dating and how is it used dating older large breasted women
It is not easily explained, in the general case, in any other way.
For further information on fitting of lines to data (also known as regression analysis), see: Note that the methods used by isotope geologists (as described by York) are much more complicated than those described by Gonick.Since the data points have the same Y-value and a range of X-values, they initially fall on a horizontal line: half-lives will include zero within its range of uncertainty.(The range of uncertainty varies, and may be as much as an order of magnitude different from the approximate value above.Unfortunately, one must wade through some hefty math in order to understand the procedures used to fit isochron lines to data.General comments on "dating assumptions" All radiometric dating methods require, in order to produce accurate ages, certain initial conditions and lack of contamination over time.Each such age would match the result given by the isochron.Gain or loss of In order to make the figures easy to read (and quick to draw), the examples in this paper include few data points.(For brevity's sake, hereafter I will refer to the parent isotope as ).In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.It depends on the accuracy of the measurements and the fit of the data to the line in each individual case.) For example, with Rb/Sr isochron dating, any age less than a few tens of millions of years is usually indistinguishable from zero.That encompasses the entire young-Earth timescale thousands of times over." in the decay equation.
