#4 - Surviving the Tsunami

Season 38 - Episode 12 - Aired 9/28/2011

The earthquake that hit the northern coast of Japan on March 11, 2011, was recorded at magnitude 9.0 the worst ever recorded in Japan. It generated an unprecedented tsunami, obliterating coastal villages and towns in a matter of minutes. In some areas, the tsunami climbed above 100 feet in height and traveled miles inland. Amazingly, amateur and professional photographers captured it all on video, including remarkable tales of human survival, as ordinary citizens became heroes in a drama they never could have imagined. As the waves rush in, a daughter struggles to help her elderly mother ascend their rooftop to safety; a man climbs onto an overpass just as the wave overtakes his car. These never-before-seen stories are captured in video and retold after the fact by the survivors who reveal what they were thinking as they made their life-saving decisions. Their stories provide lessons for how we should all act in the face of life-threatening disasters.

#15 - Smartest Machine on Earth

Season 38 - Episode 6 - Aired 2/9/2011

Augmenting human intelligence is a lot tougher than it looks, and the promise of "Hal" from 2001: A Space Odyssey is still just a fantasy. But scientists are edging closer with machines like "Watson," an IBM computing system that is gearing up for a first-of-its-kind challenge: taking on human contestants on the game show Jeopardy! With a brain the size of 2,400 home computers and a database of about 10 million documents, will Watson be able to compute its way to victory? Given the complexity of human language, could any computer truly understand it? It remains to be seen if this amalgam of circuits and silicon can really take us closer to the dream of a fully developed artificial intelligence, a truly "conscious" machine. Win or lose, the difficulty of mimicking the human thought process with software is showing artificial-intelligence researchers that there's more than one way to be "intelligent."

Fifty years after the historic mission, the Apollo 8 astronauts and engineers recount the feats of engineering that paved the way to the moon.
