If you’re anything like me, you’ve thought to yourself: “Silicon Valley is pretty big, and its impact on business and technology is pretty mind-blowing. But if you were to lay Silicon Valley on top of, oh, Kansas City, how big would it seem then?”Oh. Well that was easy.Thanks to a new super cool mapping service by the BBC, you can now overlay famous and/or newsworthy geographic regions onto any zipcode you’d like. The idea being that it helps to provide a unique and fun way to understand scale.Which reminds me. I’ve been thinking a lot about China’s Three Gorges Dam, which is the one of the biggest hydropower-complxes in the world, costing about $24 billion. I mean this thing sounds huge, but would it even span the width of Manhattan?Nope! And what about that BP oil spill? What would that have looked like if it had happened not in the Gulf of Mexico, but right on top of BP headquarters?Bloody-o.
