In 1908 the British Association for the Advancement of Science met in Dublin, and the Irish geologist and physicist John Joly (1857—1933) served as President of Section C: Geology. For his address he took the theme of "Uranium and Geology" — and in this summation of his work on radioactive materials in rocks, published the following year, he discussed their role in the generation of the Earth's internal heat.
