The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960.

This restriction extends to animals that consume seafood in their diet.

What methods do they use and how do these methods work?

In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.

Carbon-14 is also passed onto the animals that eat those plants.

Yesterday I went with some friends to a bar and we were hanging out and having a good time, then I saw this really beautiful girl, she was technically alone so I decided to go and have a chat with her, the thing that I remember the most about this girl is that she was very shy, well the point is that when I was talking to this girl a guy tried to hit me from behind, but my friends saw him and stopped him by grabbing him by the arms, suddenly this girl started yelling at me saying that I was a beast and stuff like that, after that we (me, my friends and this particular couple) got kicked out from this club, I was just astonished, not beacuse I got kicked out no, but the fact that the guy that was with this girl was her boyfriend and he was ugly as **** ...he was a douchebag, I was like WTF why women are with ugly men? Wait beast as in awesome/cool,etc or beast as in ugly,disgusting,etc? Now we all can agree a 1,000 pound person is ugly i'm sure.
