Boltwood Estimate…
Credit: Public Domain Topics: Applied Physics, Education, History, Materials Science, Philosophy, Radiation, Research We take for granted that Earth is very old, almost incomprehensibly so. But for much of human history, estimates of Earth’s age were scattershot at best. In February 1907, a chemist named Bertram Boltwood published a paper in the American Journal of Science detailing a novelContinue reading “Boltwood Estimate…”
