How we know
Go away. Specifically, go read How We Know by Jonah Lehrer from the september issue of Seed Magazine - a great piece on how we learn, the importance of doing, monkeys, rat dreams, and ice cream.
I suppose I should put this in a post of its own, but I ain't gonna. The August issue of Wired has a collection of how-tos on a varying bunch of topics. If you want to Take Great Photos, Be More Productive or simply Save the Earth, to name a few, you should read that. Instead of this. I said go away.
