Lot's of interesting stuff there too.

This is Google Tech talk describing the extraordinary restoration, imaging and deciphering effort of the Archimedes Palimpsest (a palimpsest is a manuscript which has been re-used by scraping off the original text and writing over the top).

(The following is quoted from http://video.google.com/videoplay?docid=8211813884612792878)

The Archimedes Palimpsest is a 10th Century medieval manuscript that is the subject of an ongoing technical, scientific and conservation effort at the Walters Art Museum in Baltimore, Maryland. Since 1999, the multidisciplinary team has been disbinding, conserving, imaging, analyzing, transcribing and studying the 174 parchment folios – yielding approximately 400Gb of data to date.

The Palimpsest, which the team affectionately calls “Archie,” includes at least seven treatises by Archimedes: The only copies of two of his Treatises, The Method and Stomachion; the only copy in Greek of On Floating Bodies; and copies of the Equilibrium of Planes, Spiral Lines, The Measurement of the Circle, and Sphere and Cylinder.

It also contains 10 pages of text by the 4th century B.C. Attic Greek orator Hyperides; six folios from a Neo-Platonic philosophical text that has yet to be identified, but may be commentaries on Aristotle; four folios from a liturgical book; and twelve pages from two different books, the text of which has yet to be deciphered.
