The first (accurate) atomic clock, designed by Louis Essen at the National Physical Laboratory in 1955, occupied most of a large room. The Long Now Foundation’s 10,000 year clock, which aims to keep accurate time without any power source other than elbow grease ’til the year 12,000, will take up most of a mountain.
The brainchild of Stewart Brand, founder of The Whole Earth Catalog, and designer Danny Hillis, the big clock’s mix of best of the old/best of the new technology is being brought to bear to ensure its durability, maintainability, and safety from vandals without resorting to written instructions, warning labels, or necessitating any living intervention whatsoever. The clock is scheduled to be finished… soon.
