Invisible Universe Revealed (Episode #4208H)

KQED 9: Wed, Apr 22, 2015 -- 9:00 PM

25 years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. In honor of Hubble's landmark anniversary, Nova tells the remarkable story of the telescope that forever changed our understanding of the cosmos and our place in it.
From its inception through its early days, when a one-millimeter engineering blunder turned the telescope into an object of ridicule, to the five heroic astronaut missions that returned Hubble to the cutting edge of science, Nova hears from the scientists and engineers on the front line who tell the amazing Hubble story as never before. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars and planets, advanced our understanding of dark energy and cosmic expansion, and uncovered black holes lurking at the heart of galaxies. For more than a generation, Hubble's stunning images have brought the beauty of the heavens to millions, revealing a cosmos richer and more wondrous than we ever imagined. Join Nova for the story of this magnificent machine and its astonishing discoveries.

Oklahoma's Deadliest Tornadoes (Episode #4015H)

KQED Plus: Wed, Apr 22, 2015 -- 3:00 AM

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.

Megastorm Aftermath (Episode #4017H)

KQED Plus: Wed, Apr 22, 2015 -- 2:00 AM

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?

The Great Math Mystery (Episode #4207H)

KQED 9: Wed, Apr 15, 2015 -- 9:00 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.

3D Spies of WWII (Episode #3903H)

KQED World: Sat, Apr 11, 2015 -- 10:00 PM

Hitler's scientists developed terrifying new weapons of mass destruction. Alarmed by rumors about advanced rockets and missiles, Allied intelligence recruited a team of brilliant minds from British universities and Hollywood studios to a country house near London. Here, they secretly pored over millions of air photos shot at great risk over German territory by specially converted, high-flying Spitfires. Peering at the photos through 3D stereoscopes, the team spotted telltale clues that revealed hidden Nazi rocket bases. The photos led to devastating Allied bombing raids that were crucial setbacks to the German rocket program and helped ensure the success of the D-Day landings. With 3D graphics that recreate exactly what the photo spies saw, NOVA tells the suspenseful, previously untold story of air photo intelligence that played a vital role in defeating Hitler.

Building Wonders: Hagia Sophia - Istanbul's Ancient Mystery (Episode #4204H)

KQED Life: Mon, Apr 6, 2015 -- 8:00 PM

The soaring dome of Hagia Sophia dominates Istanbul's skyline. Whether serving as Christian church, Islamic mosque, or secular museum, this magnificent building has inspired reverence and awe. For eight hundred years, it was the largest enclosed building in the world; the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537 AD? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets.
Nova follows the team's discoveries as they examine the building's unique structure and other ingenious design strategies that have insured the dome's survival. At the climax to the show, the engineers build a massive 8-ton model of the building's core structure, place it on a motorized shake table and hit it with a series of simulated quakes, pushing it collapse -a fate that the team is determined to avoid in the real world. The Unshakeable Hagia Sophia is a detective story that reveals how this architectural wonder has proven so resilient for so long, and how it came to serve as a proud expression for the great civilizations that adopted it as a symbol.
