Rutherford's Theory of the Earth's Age

Rutherford realized that radioactivity in the earth's crust would generate extra heat, which would bollax kelvin's theories about a simple heat loss into space. But however dotty kelvin got, he was still a force in scientific politics. And demolishing the old man's proudest calculation could, in turn jeopardize r Rutherford's career. With no politics stopping him, rutherford became an eminent peer himself and later ended up his scientific royalty too.
