| Video Discription | http://www.facebook.com/ScienceReason 1. "Physics (Chapter 2): Carbon Dating: (How) Does It Work?" The Cassiopeia Project is an effort to make high quality science videos available to everyone. If you can visualize it, then understanding is not far behind. 2. "The Age of Our World Made Easy (for schools)" Methods of dating easily explained, that clearly prove the age of the Earth and our universe. Part of the "Made Easy" series that explains science in clear and simple terms. A must for people who think the world is just 6,000 years old. Potholer's channel is dedicated to explaining science in a way that most intelligent people can understand. He hates seeing science manipulated and cherry-picked to support religious and ideological beliefs, usually by people with little scientific training or understanding. • http://www.youtube.com/potholer54 • http://www.youtube.com/Potholer54debunks --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- Carbon is a critical ingredient for life on Earth. All living things are made up of about 25% carbon. The carbon atom is unique because it can bind to other carbon atoms to form long chains and rings and these in turn serve as the backbone of the complex molecules that make life possible. The nucleus of a typical carbon atom has 6 protons and 6 neutrons. But about one carbon atom out of every 100 has one extra neutron. This has very little effect on the properties of the carbon, other than making it slightly heavier. Chemically, it acts just like any other carbon atom. It is called Carbon-13. And there is an even rarer type of carbon. It is formed high in the atmosphere when cosmic rays strike atoms of nitrogen converting them into Carbon -14. Carbon-14 is also chemically identical to regular carbon. But the nucleus of carbon-14 is unstable. After some amount of time, which could range from a few days to many thousands of years, carbon-14 decays back into nitrogen. But since carbon-14 is formed at a steady rate, there is a constant level of it in the environment. Out of every trillion carbon atoms in your body, only one dozen of them are carbon-14. As long as an organism is alive and eating, it maintains a constant ratio of carbon-14 to regular carbon. But once an organism dies, the amount of carbon-14 in its body begins to decrease. After 5000 years about half of the original number of carbon-14 atoms will have decayed. Using this fact, scientists can tell how long ago an organism died. • http://www.cassiopeiaproject.com .
