Many get fed up with Ken Ham and Answers in Genesis continually misrepresented normal science. This is a good summary of why his recent porkies are pure Ham. Isochron dating bypasses the necessity of knowing the quantity of initial daughter product in the rock by not using that value in the computation. Instead of using the initial quantity of daughter isotope, the ratio of daughter isotope compared to another isotope of the same element which is not the product of any decay process is used as the comparison for isochron dating. The plot of the ratios of the number of atoms of the parent isotope to the number of atoms in the non-daughter isotope compared to the number of atoms of the daughter isotope to the non-daughter isotope should result in a straight line that intersects the vertical y-axis which is the ratio of daughter to non-daughter isotopes. This point of intersection gives the initial ratio of daughter to non-daughter isotopes, which would also be the ratio in a mineral that crystallized without any parent isotope present.

Flaws in Dating? Roland Watts. Matt's style is to post a link from a creationist web site, usually Answers in Genesis, which contains the usual bunkum that has been refuted many times then to refuse to acknowledge any rebuttals. Below is a critical look at one of Matt's typical posts.
Six research scientists with specialized training in Geology, Geophysics, Astrophysics, and Physics met to report on research completed over the past year. They also discussed plans for future activities. An initial approach taken by some of the investigators is to explore models for accelerated rates of decay of radioisotopes during Creation, the Fall, or the Flood.
