These are some of the TED Talks that had you looking at the world differently by the time the credits rolled (in no specific order).

This week, during a computer security conference in Las Vegas, researchers Chris Valasek and Charlie Miller demonstrated how easily they could hack into the systems of moving cars using just a laptop computer.

In today’s talk, Nilofer Merchant gives a startling statistic: we’re sitting, on average, for 9.3 hours per day—far more than the 7.7 hours we spend sleeping. “Sitting is so incredibly prevalent, we don’t even question how much we’re doing it,” Merchant says. “In that way, sitting has become the smoking of our generation.” But there are c...

Bound by the cold concrete and oppressive steel of prison walls, this human cocoon has produced a transformational process from criminal to Christian, achieving self-acceptance and hope. "I describe myself as different in almost every way. I strive to be a student of life and a Man of God, always learning from the things around me. Seeing the...

Our next speaker, Mr. Steve Miller, is a math and computer science teacher as well as our mathematics curriculum leader. He received his bachelor’s degree in computer science from the University...

How to use the power of your friendships to make a real difference in the world
