Eureka! Hidden Archimedes Text Revealed.

Scientists used X-Ray fluorescence to discover hidden text written by Archimedes:

"When the X-rays hit an iron atom it emits a characteristic radiation, it glows," says Dr Bergmann. "When you record the glow you can reconstruct an image of all of the iron in the book."

The glowing words are displayed on a computer screen, giving the researchers the first glimpse of the text in nearly 800 years.

"It’s like receiving a fax from the 3rd Century BC," said Mr Noel. "It’s the most sensational feeling."
