Eureka! Archimedes Revealed

pin_gween writes "The Mercury News has an AP wire that shows science uncovering history. 800 years ago a monk scrubbed the text off a goatskin parchment to write prayers. Nothing unusual there, except the parchment contained writings from a copy of Archimedes' Palimpsest. Now scientists are using x-rays, generated by a particle accelerator, to cause tiny amounts of iron left by the original ink to glow without harming the delicate goatskin parchment. It takes 12 hours to scan one page, then the information is posted online."

  1. So you'll know ... by Selanit · · Score: 5, Informative

    This is a fairly obscure term, so most non-specialists don't know it. A "palimpsest" is a piece of parchment that has been re-used. This particular palimpsest contains stuff by Archimedes; and so it is called "the Archimedes Palimpsest." It is not "a copy of Archimedes' Palimpsest," it is THE Archimedes palimpsest.

    Finally I can use my LIS nerdiness on slashdot, bastion of computer, science, and math nerds.

    The summary says "Nothing unusual there, except the parchment contained writings from a copy of Archimedes' Palimpsest," using the term palimpsest incorrectly. By calling it "a copy of Archimedes' Palimpsest," the summary implies that Archimedes wrote something--a Palimpsest--which was then copied and found on this random scrap of parchment.

    In actuality, a palimpsest is a parchment already inscribed where the original ink was scraped off for reuse. Parchment, being the skin of a calf, sheep or goat, was in the Middle Ages very expensive (there is an argument that the Gutenberg revolution was fuelled more by cheap paper then by the printing press, but I digress). It was not discarded, but often reused by monks in Medieval scriptoria.

    Many works from antiquity, once thought lost, are found serendipitously through palimpsest, many of them pagan works overwritten in favour of Christian ones. So, what we have found is a palimpsest of a manuscript copy of Archimedes, not a copy of Archimedes' palimpsest

    a hard line between the academics and the "public"...

          The hard line is in your head. Scientists are part of "the public".

          The only thing stopping you from becoming a scientist is a few years of education. During this process you will not only learn the important stuff but also more importantly you will learn where and how to find the knowledge you need. There's no conspiracy to keep information from you, but it seems that you want to know things without actually having to learn them. No one is obligated to pour knowledge into your head. That stopped once mom and dad got fed up of answering your questions as a toddler. You can find all of those "obscure science magazines" at any decent library, or online. Perhaps you would also like to complain about scientists writing in "obscure technical jargon" in these magazines as well?
