Smartest Machine On Earth (Episode #3806)

KQED Plus: Tue, Apr 30, 2013 -- 8:00 PM

What's so special about human intelligence and will scientists ever build a computer that rivals the flexibility and power of a human brain? In "Artificial Intelligence," NOVA takes viewers inside an IBM lab where a crack team has been working for nearly three years to perfect a machine that can answer any question. The scientists hope their machine will be able to beat expert contestants in one of the USA's most challenging TV quiz shows -- Jeopardy, which has entertained viewers for over four decades. "Artificial Intelligence" presents the exclusive inside story of how the IBM team developed the world's smartest computer from scratch. Now they're racing to finish it for a special Jeopardy airdate in February 2011. They've built an exact replica of the studio at its research lab near New York and invited past champions to compete against the machine, a big black box code -- named Watson after IBM's founder, Thomas J. Watson. But will Watson be able to beat out its human competition?

Australia's First 4 Billion Years: Monsters (Episode #4011H)

KQED 9: Wed, Apr 24, 2013 -- 9:00 PM

Of all the continents on Earth, none preserves a more spectacular story of its origins than Australia. Nova's mini-series takes viewers on a rollicking adventure from the birth of the Earth to the emergence of the world we know today. With help from high-energy host and scientist Richard Smith, we meet titanic dinosaurs and giant kangaroos, sea monsters and prehistoric crustaceans, disappearing mountains and deadly asteroids. This is the untold story of the Land Down Under, the one island continent that has got it all.

Hunting The Elements (Episode #3906H)

KQED Plus: Tue, Apr 23, 2013 -- 8:00 PM

What are things made of? It's a simple question with an astonishing answer. Fewer than 100 naturally occurring elements form the ingredients of everything in our world -- from solid rocks to ethereal gases, from scorching acids to the living cells in our body. David Pogue, lively host of Nova's popular "Making Stuff" series and personal technology correspondent for "The New York Times," spins viewers through the world of weird, extreme chemistry on a quest to unlock the secrets of the elements. Why are some elements, like platinum and gold, relatively inert while others, like phosphorus and potassium, are violently explosive? Why are some vital to every breath we take while others are potentially lethal? Punctuated by surprising and often alarming experiments, Pogue takes NOVA on a roller coaster ride through nature's hidden lab and the compelling stories of discovery that revealed its secrets.

Japan's Killer Quake (Episode #3810H)

KQED Plus: Tue, Apr 9, 2013 -- 9:00 PM

In its worst crisis since World War II, Japan faces disaster on an epic scale: a rising death toll in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear reactor meltdowns. The facts and figures are astonishing. The March 11th earthquake was the world's fourth largest earthquake since record keeping began in 1900 and the worst ever to shake Japan. The seismic shock wave released over 4,000 times the energy of the largest nuclear test ever conducted; it shifted the earth's axis by 6 inches and shortened the day by a few millionths of a second. The tsunami slammed Japan's coast with 30 feet-high waves that traveled 6 miles inland, obliterating entire towns in a matter of minutes. This program combines authoritative on-the-spot reporting, personal stories of tragedy and survival, compelling eyewitness videos, explanatory graphics and exclusive helicopter footage for a unique look at the science behind the catastrophe.

Ancient Computer (Episode #4007H)

KQED 9: Wed, Apr 3, 2013 -- 9:00 PM

An unpromising lump of metal found in a 2000-year-old shipwreck turns out to be an extraordinary treasure: the world's first computer. Nova follows the ingenious detective work that painstakingly discovered the truth about the ancient Greek device: it was an astonishingly sophisticated astronomical calculator and eclipse predictor, unrivaled until the era of modern science and believed to be from the workshop of Archimedes.

Mind of a Rampage Killer (Episode #4008H)

KQED Plus: Tue, Apr 2, 2013 -- 9:00 PM

What makes a person walk into a theater or a church or a classroom full of students and open fire? What combination of circumstances compels a human being to commit the most inhuman of crimes? Can science in any way help us understand these horrific events and provide clues as to how to prevent them in the future?
As the nation tries to understand the tragic events at Newtown, Miles O'Brien separates fact from fiction, investigating new theories that the most destructive rampage killers are driven most of all, not by the urge to kill, but the wish to die. Could suicide and the desire to go out in a media-fueled blaze of glory be the main motivation? How much can science tell us about a brain at risk for violence? Most importantly, can we recognize dangerous minds in time - and stop the next Newtown?

Meteor Strike (Episode #4013)

KQED World: Tue, Apr 2, 2013 -- 7:00 AM

A blinding streak of light screaming across the Russian sky, followed by a shuddering blast strong enough to damage buildings and send more than 1000 people to the hospital. On the morning of February 15th, a 7000 ton asteroid crashed into the Earth's atmosphere, exploded and fell to earth across a wide swath near the Ural mountains. According to NASA, the Siberian Meteor, which exploded with the power of 30 Hiroshima bombs, was the largest object to burst in the atmosphere since a 1908 event near Siberia's Tunguska river. That time there were few eyewitnesses and no record of the event except for thousands of acres of flattened trees. This time however the event was captured by countless digital dashboard cameras, which have lately become a common fixture in Russian autos and trucks.
Within days, armed with this unprecedented crowd-sourced material, Nova crews hit the ground in Russia along with impact scientists as they hunt for debris from the explosion and clues to the meteor's origin and makeup. To understand how lucky we were this time, we explore even greater explosions in the past, from Tunguska to the asteroid that extinguished the dinosaurs 65 million years ago. This episode puts it all together and asks: Is our solar system a deadly celestial shooting gallery - with Earth in the cross-hairs? What are the chances that another, even more massive asteroid is heading straight for us? Are we just years, months or days away from a total global reboot of civilization, or worse?
