Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.

A man called Willard F Libby pioneered it at the University of Chicago in the 50's. This is now the most widely used method of age estimation in the field of archaeology.

The oldest and most widely used dating method in archaeology is typological dating.

An artefact is dated on the basis of knowledge about the age of other similar artefacts.

It's nice to just have a normal lunch and have normal people around you. (All laugh.} L: Listen, when the little sucker comes out, obviously you're coming to the bris? This isn't my first day at the rodeo and I really haven't seen anything that hasn't been circumcised. Sheldon Cooper's attractive twin sister Missy is introduced. (laugh track) Rajesh: (Mocking Howard, wiggling one hand) Hey, look at me, I don't have a foreskin. Rajesh goes on wiggling his hand - standing for the foreskin Howard doesn't have? When Rajesh knocks on the door, his medication has worn off and he can hardly speak, but Penny calls Missy, who says "Well hi, cutie pie, I was hoping you'd show up." (He whimpers and walks away.) While the first exchange is calculated to imply that circumcision trumps pyjamas, it is progress that Rajesh's foreskin didn't deter Missy's interest - may even have piqued it. She refuses on the basis that it's not appropriate for her to get involved.
