Accurate radiometric dating
Even less should we let that knowledge influence our judgment of the players, acting as they did in their own time, constrained by the concepts and data then available.One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists.His achievements ran from helping formulate the laws of thermodynamics to advising on the first transatlantic telegraph cable. Shelton was a philosopher of science, critical (as shown in his contribution, the 1915 article “Sea-Salt and Geologic Time”) of loose thinking and a defender of evolution in debates.Harlow Shapley, who wrote an article in 1919 on the subject, was an astronomer, responsible for the detection of the redshift in distant nebulae and hence, indirectly, for our present concept of an expanding universe. Russell, author of the 1921 article on radioactive dating, was familiar to me for his part in developing the Hetzsprung-Russell diagram for stars, but I was surprised to discover that he was also the Russell of Russell-Saunders coupling, important in atomic structure theory. The prologue to the drama is the mid-19th century recognition of the relation between heat and other kinds of energy (see the 1857 article “Source of the Sun’s Heat”).First, evolutionists strongly deny the idea that men came from the apes.They insist that both man and the apes came from a hypothetical ape-like ancestor, the evidence for which has not yet been discovered. Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War.
Evolution is best understood as an anti-God origins myth, attempting to explain man's existence without a Creator. The second referred to such topics as the detailed shape of the earth (bulging slightly at the equator) and the dynamics of the earth-moon system.The third referred to the heat of the sun, particularly the rate at which such heat is being lost, compared with the total amount of energy initially available.The third act sees the entry of a newly discovered set of physical laws—those governing radioactivity.Radioactivity offered not only a resolution to the puzzle of the earth’s energy supply but also a chronology independent of questionable geologic assumptions and a depth of time more than adequate for the processes of evolution.
