Half life and carbon 14 dating
This video explains half-life in the context of radioactive decay. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.
Carbon dating compares the ratio of carbon-12 to carbon-14 atoms in an organism.
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.
This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." Every time a living being dies a stopwatch starts ticking.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days?He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.Thus problems in calculus books read like number 11 on page 535 of by James Stewart. Chemistry on Khan Academy: Did you know that everything is made out of chemicals?Carbon dating is a real-life example of a first-order reaction. Chemistry is the study of matter: its composition, properties, and reactivity.
