Wiesner and York exhibited this courage; publishing in a science journal, they insisted that the solution to the problem was not to be found in the natural sciences.
They cautiously qualified their statement with the phrase, "It is our considered professional judgment...." Whether they were right or not is not the concern of the present article.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.
By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
However, indirect reference is likely to be made to both processes, so we give these background notes in a way that could be used with children.
Most people think that radioactive dating has proven the earth is billions of years old.
After all, textbooks, media, and museums glibly present ages of millions of years as fact.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
"The Tragedy of the Commons," Garrett Hardin, Science, 162(1968):1243-1248. It is our considered professional judgment that this dilemma has no technical solution.
