A heartbeat, a child's first word, a photograph, a phone call, a Facebook update -- all drops in a vast ocean of data. "Big" data, then, is something of a misnomer. It's colossal. From the beginning of recorded time until 2003, we created 5 billion gigabytes of data. In 2011 the same amount was created every two days. By 2013 that time will shrink to 10 minutes. So what are we learning from it all? Truths about our measured world and our measured selves. What follows is a look at both.
