Imagine stepping into an elevator and bumping into Lou Reed or Maya Angelou or Paul Newman. What would you do? What would you say? And what if the legend you bumped into on your ride up the 32nd floor was none other than the father of the comet (kind of)?
Once upon a time, you could crack open a radio, a telephone, a lawnmower, even a car, take it apart and figure out how it worked. No more. Pretty much everything we use these days comes with computer chips, which you can't really take apart. (I mean, you can, but all you'll find inside are a bunch of 1's and 0's with no obvious logic.) So car mechanics can snap a new chip into an engine, wait till it whirs and watch the gears come to life, but do they know what's going on in there? For most of us, chips are "black boxes." They work, but we don't know why.

Sometimes ideas that originate in science seep out into the broader culture and take on a life of their own. It's still common to hear people referred to as "anal," a Freudian idea that no longer has much currency in contemporary psychology. Ideas like black holes and quantum leaps play a metaphorical role that's only loosely tethered to their original scientific meanings.

There's no easy way to track all of the world's crops. What's missing, among other things, is an accurate map showing where they are.
But the people behind Geo-Wiki are hoping to fix that, with a game called Cropland Capture. They're turning people like you and me into data gatherers, or citizen scientists, to help identify cropland.
