So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living. Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.
