For example, all hydrogen atoms have one proton, all carbon atoms have 6 protons, and all uranium..Carbon-14 is an isotope of the element carbon. Most carbon atoms also have 6 neutrons, giving them an atomic mass of 12 ( = 6 protons 6 neutrons). About 4/5ths of Earth's atmosphere is nitrogen gas!

A molecule of nitrogen gas is made up of two nitrogen atoms.

Why, exactly, does carbon-14 have a half-life of nearly 6,000 years while other light atomic nuclei have half-lives of minutes or seconds?

(Half-life is the time it takes for the nuclei in a sample to decay to half the original amount.) "This has been a very significant puzzle to nuclear physicists for several decades," said James Vary, an Iowa State University professor of physics and astronomy.

Carbon-14 dating (also called "radiocarbon dating") is used to determine the age of materials that contain carbon that was originally in living things.

It is often used in archeology and some types of biology. Plants (and other autotrophs) take in carbon dioxide gas from the atmosphere during photosynthesis.

The interaction of traveling waves in dissipative systems, physical systems driven by energy dissipation, can yield unexpected and sometimes chaotic results.

NESTA welcomes new Institutional Affiliates in support of our ongoing programs, as well as collaborations on new projects.

Iowa State University physicists, left to right, Pieter Maris and James Vary have used supercomputing power to solve the puzzle of the long, slow decay of carbon-14.

That long half-life makes carbon-14 a useful tool to determine the ages of skeletons and other artifacts.
