As many as 90% of the world's languages are expected to disappear within the next century, according to experts. That's why the Rosetta Project put more than 13,000 pages of data -- in a stunning 1,500 languages -- onto a single disk not much bigger than a silver-dollar pancake.
The disk, which can be read only with the help of a 650X microscope, features information pulled from the digital archive that's being amassed by the Rosetta Project in an effort to preserve the world's languages. This electronic tome also contains details about the various languages, including information about the people who speak them.
