“I want to know the truth” is something he says a lot.Within 30,000 years, 98% of the already vanishingly small quantities of carbon-14 in bone is gone.And carbon-14 molecules from surrounding soil start to seep into the fossils.So, at his father's urging, Tom applied for and completed a Ph D at the University of Waikato's Radiocarbon Dating Laboratory in Hamilton, then did a postdoc there.And when a faculty position became available at a better-funded lab at the University of Oxford in 2000, he moved back to his birth country.

“We know that it is older than Christendom,” he wrote, “but whether by a couple of years or a couple of centuries or even by more than a millennium, we can do no more than guess.” The fog began to lift in the middle of the twentieth century, when US chemist Willard Libby and his colleagues showed that all formerly living things bear a clock powered by radioactive carbon-14.
