Archimedes sent a fax to XXI century | Image of the Week, Scientific American Blog Network

High powered x-rays of a 10th century prayer book reveal one of two surviving texts by the ancient Greek mathematician Archimedes. The book has been dubbed Archimedes’ Palimpsest and will be on display starting next month at the Walters Art Musuem in Baltimore, MD. William Noel, who spearheaded the effort to reveal the hidden text, notes that watching the x-ray scan results come in real-time was “like receiving a fax from the 3rd Century B.C.”
