TED talks--the buzz for this once underground conference gets louder every year in its celebration of the creative, expanding our sense of the possible. Authors have had a big impact on the conference and here's a video collection of the best of the past as well as the current line up. The topics cover everything from what we can learn from spaghetti sauce (Malcolm Gladwell) to understanding where creativity hides (Amy Tan). Others cover how population density kills, why too much choice makes us unhappy and how to re-conceive the dictionary.
