To get a mass large enough to handle, you needed to embed your sample in another substance, a "carrier." At first acetylene was used, but some workers ruefully noted that the gas was "never entirely free from explosion, as we know from experience."(4) Ways were found to use carbon dioxide instead.

Led by Professor Christopher Ramsey of Britain's Oxford University, an international team tested seeds, baskets, textiles, plant stems and fruit obtained from museums in the United States and Europe for the landmark study.landmark"For the first time, radiocarbon dating has become precise enough to constrain the history of ancient Egypt to very specific dates," said Ramsey.

An example of the ingenious technical work and hard-fought debates underlying the main story is the use of radioactive carbon-14 to assign dates to the distant past.

For other examples, see the essays on Temperatures from Fossil Shells and Arakawa's Computation Device.

De Vries thought the variation might be explained by something connected with climate, such as episodes of turnover of ocean waters.(7) Another possible explanation was that, contrary to what everyone assumed, carbon-14 was not created in the atmosphere at a uniform rate.

Some speculated that such irregularities might be caused by variations in the Earth's magnetic field.
