India has had a long religious history of contemplating nothingness.

Marcus du Sautoy, a professor of mathematics at the University of Oxford, believes that this is why the concept of zero might have been influenced through cultural practices. “Much ado about nothing: ancient Indian text contains earliest zero symbol.” The Guardian, 13 Sept.

Other tested samples included part of the deck of a funeral ship placed in the tomb of Sesostris III of Egypt, the heartwood of one of the largest redwood trees ever cut, and the linen wrapping one of the Dead Sea Scrolls.

The second edition of Libby's , published by the University of Chicago Press in 1955, lists 27 pages of objects for which he had obtained radiocarbon dates before the fall of 1954.

Scientists soon used the technique on materials ranging from the dung of a giant sloth from a Nevada cave; seaweed and algae from Monte Verde, Chile, the oldest archaeological site in the Western Hemisphere; the Shroud of Turin; and the meteorite that created the Henbury Craters in northern Australia.

It was while working in the Kent Laboratory building in the 1940s that Prof.

One sample came from 885-993 AD, another from 680-779, and the most shocking from 224-383 AD.Archaeologists testing the ages of artifacts from multiple sites across the Eastern and Western hemispheres found that civilization originated simultaneously around the world rather than in Europe.And Libby himself, when he analyzed wood samples from trees once buried beneath glacial ice, documented that North America's last Ice Age ended approximately 11,000 years ago -- not 25,000 years ago as previously believed."This radiocarbon dating method was a transformative advance to archaeology and historical studies, allowing the determination of the age of archeological sites and objects without reliance on a knowledge of local customs and history," said Viresh Rawal, professor and chair of the Department of Chemistry.Transformative research The designation of UChicago as a National Historic Chemical Landmark joins the University's 2006 designation by the American Physical Society as an historic physics site to commemorate the work of Robert Millikan, who received the 1923 Nobel Prize in physics for experiments conducted at the Ryerson Physical Laboratory building, 1100 E. A plaque commemorating that work hangs in the first-floor lobby of the Kersten Physics Teaching Center, 5720 S. Two scientists working at the University of California Radiation Laboratory in Berkeley discovered carbon-14 in 1940.
