TED talks

Suppose you were given 18 minutes to give the talk of your life. What theme would you choose? And how would you structure and present your talk to achieve the greatest impact? This is the basic challenge that faces a speaker at a TED conference. 2010 was a vintage year. I've only listened to two of the talks, but either one of them is proof enough:

• Benoît Mandelbrot on "Fractals and the art of roughness"
• Daniel Kahneman on "The riddle of experience vs. memory"
