Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.
He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Wiens has a Ph D in Physics, with a minor in Geology.
Some of the most commonly used radiometric schemes are [Dalrymple1991, pg. 55]: Each method has its own particular range of applicability, which derives from the half-life of the particular radioactive decay involved.
Uranium-thorium dating, for instance, can be used to date specimens up to about 500,000 years old (since the half-life of the U-Th decay is 75,000 years), but Rubidium-Strontium dating can be used to date specimens billions of years old (since the half-life of the Rb-Sr decay is 48.8 billion years).
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.
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
