Very nice short clips have been posted at  http://www.youtube.com/user/4universalshiva#p/u . These are very important because the philosophy is very ancient and coming here from the original lineage

Think of them as forces, just like we have gravity and electromagnetism working on larger distances. We also have Strong and Weak Nuclear forces working on sub atomic levels.

The plants maintain a certain amount of carbon-14 level in sync with the atmospheric level due to photosynthesis. Then when animals eat plants they maintain that same level as well. When an animal is dead, the carbon 14 starts to decay into Nitrogen 14 (it takes 5700 years for the amount to become half of what it was initially ;also called the half life) If we know how much carbon-14 is left in that animal then we can know how long it has been dead.

Common Cold is a virus as opposed to a bacteria. Antibiotic can only act on bacteria as the bacteria is living organism. Virus is a packet of DNA or RNA embedded in a protein that masquerades itself and enters a living cell. It then takes over the entire metabolic process of the cell to destroy the cell it entered and uses it to create more protein packets like itself ready to attack other cells.
