First Man on the Moon (Episode #4122H)

KQED 9: Wed, May 27, 2015 -- 9:00 PM

When Neil Armstrong set foot on the moon, he won instant fame. Yet this accomplished engineer and test pilot was so determined to stay out of the limelight that few know the personal story of how his rare combination of talent, luck and experience led to his successful command of Apollo 11. Nova presents an intimate portrait of an unassuming American hero through interviews with Armstrong's family and friends.

Rise of the Hackers (Episode #4115H)

KQED World: Sat, May 23, 2015 -- 10:00 PM

Our lives are going digital. We shop, bank and even date online. Computers hold our treasured photographs, private emails and all of our personal information. This data is precious - and cybercriminals want it. Now, Nova goes behind the scenes of the fast-paced world of cryptography to meet the scientists battling to keep our data safe. They are experts in extreme physics, math, and a new field called "ultra-paranoid computing," all working to forge unbreakable codes and build ultra-fast computers. From the two men who uncovered the world's most advanced cyber weapon to the computer expert who worked out how to hack into cash machines and scientists who believe they can store a password in your unconscious brain, Nova investigates how a new global geek squad is harnessing cutting-edge science - all to stay one step ahead of the hackers.

The Great Math Mystery (Episode #4207H)

KQED Life: Fri, May 22, 2015 -- 8:00 PM

Nova leads viewers on a mathematical mystery tour - a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson, and the successful landing of rovers on Mars. But where does math get its power?
Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind's clever trick, or the language of the universe? The Great Math Mystery is a show for everyone; whether we think we're good with numbers or not, we all use math in our daily lives. It sheds fascinating light on how math works in our brains and ponders the ultimate mystery of why it works so well when decoding the universe.

Lethal Seas (Episode #4211H)

KQED World: Sat, May 16, 2015 -- 10:00 PM

A deadly recipe threatens the survival of countless creatures throughout Earth's oceans. We've known for years that oceans absorb about a quarter of the carbon dioxide in our atmosphere. With carbon emissions sharply rising, the silent killer is entering the seas at a staggering rate - raising the oceans' acidity. As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century. Can experts crack the code of a rapidly changing ocean - before it's too late?

Megastorm Aftermath (Episode #4017H)

KQED Life: Fri, May 15, 2015 -- 8:00 PM

One year after Hurricane Sandy's deadly strike, Nova follows up on its 2012 film "Inside the Megastorm" with a fresh investigation of the critical questions raised by this historic storm: Was Sandy a freak combination of weather systems? Or are hurricanes increasing in intensity due to a changing climate? What can we do to prepare ourselves for the next Sandy and what progress has been made toward making our urban infrastructure more resilient? Much of Sandy's wrecking power was due to an extreme storm surge that left large swaths of New York and New Jersey underwater. And with sea levels on the rise, flooding will only become more frequent. What is the role of global warming in driving these rising seas and what will it take to make cities like New York more resilient? Nova travels around the world to see how other low-lying urban areas are combining extraordinary engineering with natural landscape restoration and a smarter, more flexible power grid to prepare for an uncertain future. At the same time, Nova meets the climate scientists who are racing to understand how a warming world will affect extreme - but unpredictable - weather phenomena like hurricanes and tornadoes. To many, Sandy was a wake-up call: one year later, are we still listening? And how will we answer?

Nazi Attack On America (Episode #4210H)

KQED World: Sat, May 9, 2015 -- 10:00 PM

Long before 9/11, a far deadlier, little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub's sinking.

Oklahoma's Deadliest Tornadoes (Episode #4015H)

KQED Life: Fri, May 8, 2015 -- 8:00 PM

On May 20th 2013, a ferocious F5 tornado over a mile wide tore through Moore, Oklahoma, inflicting 24 deaths and obliterating entire neighborhoods. It was the third time an exceptionally violent tornado had struck the city in 14 years. Yet predicting when and where these killer storms will hit still poses a huge challenge. Why was 2011 - the worst ever recorded tornado season that left 158 dead in Joplin, Missouri - followed by the quietest ever year of activity prior to the Moore disaster? Can improved radar and warning technology explain why so many fewer died in Moore than in Joplin? And will tornadoes get worse as Earth's climate heats up? In this Nova special, we meet scientists in the front ranks of the battle to understand these extreme weather events. We also meet storm survivors whose lives have been upended, and learn how we can protect ourselves and our communities for the uncertain future.

Manhunt - Boston Bombers (Episode #4014H)

KQED Life: Mon, May 4, 2015 -- 8:00 PM

At 2:50pm on April 15, two bomb blasts turned the Boston Marathon finish line from a scene of triumph to tragedy, leaving 3 dead, hundreds injured, and a city gripped by heartbreak and terror. Less than 5 days later, the key suspects were identified and apprehended - with one dead, the other in custody. How did investigators transform the chaos of the bombing into a coherent trail of clues, pointing to the accused killers?
Nova follows the manhunt step by step, examining the role modern technology - combined with old-fashioned detective work - played in cracking the case. Given hundreds of hours of surveillance and bystander videos, how did agents spot the bad guys in a sea of spectators? Why couldn't facial recognition software I.D. the criminals? How much could bomb chemistry analysis, cell phone GPS, infrared imagery and crowd sourcing reveal about the secrets behind this horrific crime? With the help of top criminal investigators and anti-terrorism experts, Nova explores which technological innovations worked - and which didn't - in the most notorious case of today, and how the world of crime fighting could be transformed tomorrow.

Lizard Kings (Episode #3616H)

KQED Life: Fri, May 1, 2015 -- 8:00 PM

They look like dragons. Armed with sharp teeth, tearing claws and a whip-like tail, these fearsome creatures are not only powerful, they're also smart. Top predators with intelligence, who learn as they hunt, and who use their brain to track down prey, no matter what. Sounds like these cunning hunters should be a big-brained mammal, but these creatures are reptiles, members of a family that evolved when the dinosaurs roamed the earth. They are the largest lizards still walking the planet, the monitor lizards -- the Lizard Kings.
