The Long Now Foundation, a non-profit organisation that encourages long-term thinking, runs the Rosetta Project, a digital archive of the world’s languages. As part of this project, in 2008 it produced the Rosetta Disk, a nickel alloy disk measuring 7.62 cm in diameter that contains over 13,000 pages of information on over 1,500 human languages. Each page is only 400 microns across and can be read through a microscope at 650X. The disc is designed to last for thousands of years and may serve in the future as a testimony of human experience and intellect expressed in our countless languages.
