Map of America http://krvs.org/post/who-do-you-hang-map-america Look at the center of this map, at the little red dot that marks Kansas City. Technically, Kansas City is at the edge of Missouri, but here on this map it's in the upper middle section of a bigger space with strong blue borders. We don't have a name for this bigger space yet, but soon we will.<p>I would call it, for the moment, "The Part Of America Kansas City Hangs With" because that's what this map is saying. It's a new, intriguing way to see our country. This one was built by tracking dollar bill circulation. There've been similar maps built from phone call data.

Map of America The Big Squeeze: Can Cities Save The Earth? http://krvs.org/post/big-squeeze-can-cities-save-earth Let's get dense. If we take all the atoms inside you, all roughly 70,000,000,000,000,000,000,000,000,000 of them, and squeeze away all the space inside, then, <a href="https://twitter.com/bgreene/status/320173198178136066">says physicist Brian Greene</a>:<strong></strong><p>That's a very tight fit. So tight that in real life, it couldn't happen. It's not physically possible. Atoms won't crunch that close. But people, it seems, are willing to try.
