This "TED Talk" demonstrates the most amazing data analyses I have ever seen. MIT researcher, Deb Roy, wired his house for video and audio recording in every room then recorded 90,000 hours of his life, then analysed all of it: from his son learning to say "water" to cooking with his wife to every conversation they had about every television show they watched. It sounds boring, but not the way this guy presents it. The video is about 20 minutes long but stick with it you will be hooked after 5 minutes. Two paws way up.
You can watch more TED Talks here. Not all of the Talks are great and most of the website is made up of low angle photographs of smart people moving their hands while they're talking, but it's worth a look.
Thank you Boing Boing.
