Radiocarbon dating animation

by 2000 years or more as one goes further back in time clearly have important implications for understanding the resolution of dates based on radiocarbon, the duration of archaeological phenomena, and the correlation of radiocarbon dates with other types of dating, especially historical chronologies.a bad rap, what with radiation and fallout and nuclear waste and all. One of the coolest (OK, maybe the coolest) is using radioactive carbon to determine the age of old bones or plants.To understand this, you must first understand radioactivity and decay.When an element undergoes radioactive decay, it creates radiation and turns into some other element.Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance to decay.The rate of decay depends upon the number of atoms you have.

This is called the half-life—the amount of time required for one-half of a given number of atoms to disintegrate. The plot of the number of tiles as a function of the number of turns looks like this: Again, I made radioactive spheres disappear when they decayed.This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.This is exactly how carbon dating works, but with dinosaurs instead of models.A Turkish UNESCO World Heritage Site inhabited thousands of years ago will help to unlock a greater understanding of the human story, thanks to a new collaborative research project led by experts from the University of Stirling and Stanford University.

Alex Bayliss, Professor of Archaeological Science at Stirling, will use radiocarbon dating to unravel the history of the Neolithic village at Çatalhöyük East in a joint £250,000 project with Ian Hodder, Dunlevie Family Professor of Anthropology at Stanford.

The Arts and Humanities Research Council (AHRC) and the National Science Foundation (NSF) have commissioned the five-year study at the 13 hectare mud brick site, said to date from 7100BC - 5900BC.
