represents a classic architectual device used to make people feel as if they are going through a .

There is much more to discover at Stonehenge than is known today. A core team .
consisting of archaeologists, chemists, physicists, statiticians, and animal bone specialists has .
been put together for new studies on Stonehenge. The goals of the core team include the .
provision of a series of "real" dates for each major phase and the elucidation of the chronology of .
major events. Also included are the assigning of specific features to each phase. .
Dating systems of the modern use are of a new technological era. The most accurate up to .
date systems are radio-carbon dating. This is how it works. All living things contain carbon. The .
isotope C14 is absorbed by all living things and also decays upon death. The technique of radio-.
carbon dating measure the amount of C14 within an object. Radio-carbon dating first developed .
in the 1940's. It was then assumed that C14 decayed at a constant rate. In reality it seems the .
difference between "true" dates and uncorrected radio-carbon dates ay even differ as much as a .
thousand years. There is another technique that can be used to "modify" the dates. By counting .
the annual rings of growth on a tree it is possible to count back to arrive at a specific date. This .
technique is called dendrochronology. By comparing the tree ring series with the amount of C14 .
in the materials has provided a means of recalibrating radio-carbon dates. Each process includes .
