You obviously do not know science nor assumptions in radio isotope dating methods
Actually, I have a PhD in the life sciences. In the course of getting that PhD, I had to learn the physics of radioisotopes and how to use them for scientific measurements. Radioisotopic measurements are among the most precise and accurate forms of measurement there are, because the rate of radioisotopic decay remains constant over time, and the decay process is invariable. For instance, sulfur 35 *always* decays through emission of a beta particle and becomes chlorine.
I seriously doubt that the M. Min who wrote this blog piece has ever stepped foot in a science class (other than sitting through the obligatory introduction to science course required as part of general education). He (she?) is certainly no expert on science.
