Unraveling Lord Kelvin's Calculations on Earth's Age

The chapter scrutinizes Lord Kelvin's estimates of the Earth and Sun's age, revealing his method, assumptions, and conflicts with geologists. It explains how Kelvin's oversight of heat convection led to underestimating Earth's age and delayed scientific acceptance of plate tectonics. The discussion contrasts Kelvin's calculations with modern understanding, highlighting the impact of radioactive decay on the Earth's true age.
