Previously hidden writings of the ancient Greek mathematician Archimedes are being uncovered with powerful X-ray beams nearly 800 years after a Christian monk scrubbed off the text and wrote over it with prayers.
Over the past week, researchers at Stanford University's Linear Accelerator Center in Menlo Park have been using X-rays to decipher a fragile 10th century manuscript that contains the only copies of some of Archimedes' most important works.
The X-rays, generated by a particle accelerator, cause tiny amounts of iron left by the original ink to glow without harming the delicate goatskin parchment.
"We are gaining new insights into one of the founding fathers of western science," said William Noel, curator of manuscripts at Baltimore's Walters Art Museum, which organized the effort. "It is the most difficult imaging challenge on any medieval document because the book is in such terrible condition."
Following a successful trial run last year, Stanford researchers invited X-ray scientists, rare document collectors and classics scholars to take part in the 11-day project.
It takes about 12 hours to scan one page using an X-ray beam about the size of a human hair, and researchers expect to decipher up to 15 pages that resisted modern imaging techniques. After each new page is decoded, it is posted online for the public to see.
On Friday, members of the public watched the decoding process via a live Web cast arranged by the San Francisco Exploratorium.
"We are focusing on the most difficult pages where the scholars haven't been able to read the texts," said Uwe Bergmann, the Stanford physicist heading the project.
Born in the 3rd century BC, Archimedes is considered one of ancient Greece's greatest math-ematicians, perhaps best known for discovering the principle of buoyancy while taking a bath.
The 174-page manuscript, known as the Archimedes Palimpsest, contains the only copies of treatises on flotation, gravity and mathematics. Scholars believe a scribe copied them onto the goatskin parchment from the original Greek scrolls.
Three centuries later, a monk scrubbed off the Archimedes text and used the parchment to write prayers at a time when the Greek mathematician's work was less appreciated. In the early 20th century, forgers tried to boost the manuscript's value by painting religious imagery on some of the pages.
India yesterday summoned Canada’s high commissioner in India to “convey strong concern” over Sikh protesters in Canada and how they were allowed to breach the security of India’s diplomatic mission and consulates. Canadian media reported that hundreds of protesters gathered in front of the Indian consulate in Vancouver on Saturday over demands for an independent Sikh state, a simmering issue for decades that was triggered again in the past few weeks. Canada has the highest population of Sikhs outside their home state of Punjab in India. “It is expected that the Canadian government will take all steps which are required to ensure the
CONFLICTING ACCOUNTS: The US destroyer’s routine operations in the South China Sea would have ‘serious consequences,’ the defense ministry said China yesterday threatened “serious consequences” after the US Navy sailed a destroyer around the disputed Paracel Islands (Xisha Islands, 西沙群島) in the South China Sea for the second day in a row, in a move Beijing claimed was a breach of its sovereignty and security. The warning came amid growing tensions between China and the US in the region, as Washington pushes back at Beijing’s growingly assertive posture in the South China Sea, a strategic waterway it claims virtually in its entirety. On Thursday, after the US sailed the USS Milius guided-missile destroyer near the Paracel Islands, China said its navy and
‘DUAL PURPOSE’: Upgrading the port is essential for the Solomon Islands’ economy and might not be military focused, but ‘it is not about bases, it is about access,’ an analyst said The Solomon Islands has awarded a multimillion-dollar contract to a Chinese state company to upgrade an international port in Honiara in a project funded by the Asian Development Bank, a Solomon Islands official said yesterday. China Civil Engineering Construction Co (CCECC) was the only company to submit a bid in the competitive tender, Solomon Islands Ministry of Infrastructure Development official Mike Qaqara said. “This will be upgrading the old international port in Honiara and two domestic wharves in the provinces,” Qaqara said. Responding to concerns that the port could be deepened for Chinese naval access, he said there would be “no expansion.” The Solomon
The US Department of Justice on Friday unveiled spying charges against a Russian who, under a Brazilian alias, studied at a Washington university and then tried to join the International Criminal Court (ICC) in The Hague. The indictment of Sergey Vladimirovich Cherkasov said it would try to contest his extradition to Russia from Brazil, where he is jailed on identity fraud charges. Cherkasov, 39, was detained at the beginning of April last year by Dutch authorities for using fake identity papers. He arrived in the country as Viktor Muller Ferreira, a Brazilian, to take a position at the ICC as a junior analyst. The
