When granite rock hardens, it freezes radioactive elements in place.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.

All carbon atoms have a nucleus containing six protons.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).

Most carbon-14 quickly combines with oxygen to form radioactive carbon dioxide, which then spreads throughout the atmosphere.

Half of it will decay in about 5,730 years to form nitrogen.

Half of the remainder will decay in another 5,730 years, and so on.

This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.

When creation scientists studied granite samples, they made interesting discoveries.

The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes.

    And in an uncharacteristically wide-eyed mood, Savage provides a lovely tale about the thrill of anticipating a baby—even when it isn't yours (by birth)." Publishers Weekly reviewed the work and commented, "Employing the blunt tone of his columns, Savage humorously and honestly discusses his sexual practices (including bondage and fantasies involving actor Matt Damon), his ambivalence about being a parent and his rage at his homophobic grandmother.
