Malcolm Gladwell on spaghetti sauce and the pursuit of happiness

Today's Wednesday fun is a bit longer than usual, but I think this video of Malcolm Gladwell's TED talk in 2004 is worth a little extra time. You're probably wondering what spaghetti sauce has to do with science, let alone happiness, and he guides you through the food science, how that fits with our changing philosophies in other sciences, and how one man's quest to make people's tastebuds happy taught us a lot about people and figuring out what we really want.
