Timekeeping: The 10,000 Year Clock
"Time and tide wait for no man", wrote Geoffrey Chaucer. We spend our days clamoring after bigger homes, nicer cars, the ultimate vacation spot -- and time keeps ticking, someday getting the better of us. Death and taxes, as they say. Every so often, in the stillness of the night, we think about the legacy we're leaving, about what will remain that has our name stamped on it long after we're food for worms. Discomfortingly, it seems little will. Even in the world of architecture, with varied and vast creations across the globe, it's a constant struggle to keep many historic buildings intact or to actually restore them to their original glory. Some survive, and many of those buildings aren't even a century old. Others fall, their legacy continued only in photographs or history books.
