Document Summary
A big dispute in the history of science: the age of the planet earth. Georg agricola de re metallica basel, 1556. If you know how much heat loss per second, and total among lost in state one, then we can calculate the age of the earth. Depend only on two things a and deltat/l. Age(s)= (total heat loss per area)/ (heat loss per area per second) Kelvin said that we can look at this number differently, he said that the age of the earth should be related to the age of proto-earth. If the sun were made of fuel if it radiated energy that it did at the rate, it would soon extinguish. Therefore thought of how the sun operates and how the energy is made. He looked at the planetary system; know one object that was never part of the sun, the planet mercury, and the sun at the beginning of the solar system.
