From rockets to stock markets, many of humanity's most thrilling creations are powered by math. So why do kids lose interest in it? Conrad Wolfram says the part of math we teach -- calculation by hand -- isn't just tedious, it's mostly irrelevant to real mathematics and the real world. He presents his radical idea: teaching kids math through computer programming.
Ecologist Eric Berlow doesn't feel overwhelmed when faced with complex systems. He knows that more information can lead to a better, simpler solution.

Aboard Mission Blue, scientist Greg Stone tells the story of how he helped the Republic of Kiribati to create an enormous protected area in the middle of the Pacific -- protecting fish, sealife and perhaps the island nation itself.
We're bringing gameplay into more aspects of our lives, spending countless hours -- and real money -- exploring virtual worlds for imaginary treasures. Why? As Tom Chatfield shows, games are perfectly tuned to dole out rewards that engage the brain and keep us questing for more.
