Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects.

From rockets to stock markets, many of humanity's most thrilling creations are powered by math. So why do kids lose interest in it?

He presents his radical idea: teaching kids math through computer programming.

Education scientist Sugata Mitra tackles one of the greatest problems of education — the best teachers and schools don't exist where they're needed most. In a series of real-life experiments from New Delhi to South Africa to Italy, he gave kids self-supervised access to the web and saw results that could revolutionize how we think about teaching.

Less than 10% of plastic trash is recycled — compared to almost 90% of metals — because of the massively complicated problem of finding and sorting the different kinds. Frustrated by this waste, Mike Biddle has developed a cheap and incredibly energy efficient plant that can, and does, recycle any kind of plastic.

New York City residents produce 11,000 tons of garbage every day. Every day! This astonishing statistic is just one of the reasons Robin Nagle started a research project with the city's Department of Sanitation.

The Story of Bottled Water, released on March 22, 2010 (World Water Day) employs the Story of Stuff style to tell the story of manufactured demand—how you get Americans to buy more than half a billion bottles of water every week when it already flows from the tap. Over five minutes, the film explores the bottled water industrys attacks on tap water and its use of seductive, environmental-themed advertising to cover up the mountains of plastic waste it produces. The film concludes with a call to take back the tap, not only by making a personal commitment to avoid bottled water, but by supporting investments in clean, available tap water for all.

The Story of Electronics explores the high-tech revolution's collateral damage—25 million tons of e-waste and counting, poisoned workers and a public left holding the bill. Host Annie Leonard takes viewers from the mines and factories where our gadgets begin to the horrific backyard recycling shops in China where many end up. The film concludes with a call for a green 'race to the top' where designers compete to make long-lasting, toxic-free products that are fully and easily recyclable.
