Theory behind carbon dating

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

A fourth allotrope of carbon, known as white carbon, was produced in 1969.

It is a transparent material that can split a single beam of light into two beams, a property known as birefringence. Large molecules consisting only of carbon, known as buckminsterfullerenes, or buckyballs, have recently been discovered and are currently the subject of much scientific interest.

The carbon-14 within that organism is no longer replaced and the percentage of carbon-14 begins to decrease as it decays.

By measuring the percentage of carbon-14 in the remains of an organism, and by assuming that the natural abundance of carbon-14 has remained constant over time, scientists can estimate when that organism died.

Coke is made by heating soft coal in an oven without allowing oxygen to mix with it.

Although commonly called lead, the black material used in pencils is actually graphite.

A single buckyball consists of 60 or 70 carbon atoms (C) linked together in a structure that looks like a soccer ball.

They can trap other atoms within their framework, appear to be capable of withstanding great pressures and have magnetic and superconductive properties.

Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.

Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.

Perhaps you have heard of Ice Man, a man living in the Alps who died and was entombed in glacial ice until recently when the ice moved and melted.
