Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

In principle, any material of plant or animal origin, including textiles, wood, bones and leather, can be dated by its content of carbon 14, a radioactive form of carbon in the environment that is incorporated by all living things.

Because it is radioactive, carbon 14 steadily decays into other substances.

In some cases, the latter ratio appears to be a much more accurate gauge of age than the customary method of carbon dating, the scientists said.

If you had a bucket of coins and you threw them up in the air, it would be strange if they all came down heads.

Most people would be weirded out if 75% heads of the coins came down heads.

Physicist: The predictability of large numbers of random events is called the “law of large numbers“.

It causes the margin of error to be essentially zero when the number of random things becomes very large.For example, a problem I have worked on involving the eruption of a volcano at what is now Naples, Italy, occurred 38500 years ago with a plus or minus of 300 years.
