The onset of geology quickly showed that you just couldn’t fit all that rock into 6000 years, and Jackson covers the speculations of Lyell, Hutton and other early rock-hammerers. Serious estimation attempts included trying to establish sedimentary denudation rates and increasing ocean salinity measurements, which gave immense age ranges (from 20My to 1.5Gy); however, the question was definitively settled by Lord Kelvin, who calculated, based on the assumption that solar heat was due to gravitational contraction, that the Sun (and therefore the Earth) was about 60My old. Since Kelvin was the world’s foremost physicist, that settled the question once and for all, which turned out to be about two years (when the Curies discovered radium). Kelvin never did accept radioactivity, feeling that the radium had absorbed heat from elsewhere and was now giving it off again.
Jackson concludes by covering the early days of radiometric dating up to 1956, when Clair Patterson published 4.550Gy for the age of meteorites (and therefore the solar system, and therefore the Earth).
Entertaining, and probably quite useful for debates with YECs, who always seem to dredge up sedimentary denudation and salinity arguments. It would have been nice to include just a little more explanation of why these methods didn’t work. But you can’t have everything.… (altro)
