The Europeans get all the press. They've got all that history of old empires and discoverers and globe-spanning explorers. Columbus, Copernicus, Magellan. Ah, but who's writing the history? It may just be that Europe's got all the PR. There's two sides to every coin. What if the history books are wrong sometimes? What if, for example, China was out and about discovering stuff decades before Christopher Columbus even boarded a ship? Anthropologists have just unearthed a 600-year-old coin near Kenya that proves that China was hip to trading a long, long time ago.

What happens when you set a coin rolling on a treadmill? Will it keep rolling perpetually until outside forces cause it stop? That's a good question, and one that we can safely say has an answer now. YouTube user Parker Reed set out to, well, it's not really clear what he set out to accomplish. Whatever it was, Reed ended up setting a nickel rolling on a treadmill and recorded an entire hour worth of video. It's actually a surprisingly zen 60 minutes of a single rolling coin and treadmill background noise.
