Secrets of the Viking Sword (Episode #3913#)

KQED 9: Wed, Sep 25, 2013 -- 9:00 PM

The Vikings were among the fiercest warriors of all time. Yet only a select few carried the ultimate weapon of their era: the feared Ulfberht sword. Fashioned using a process that would remain unknown to the Vikings' rivals for centuries, the Ulfberht was a revolutionary high-tech tool as well as a work of art. Considered one of the greatest swords ever made, it remains a fearsome weapon more than a millennium after it last saw battle. But how did Viking sword makers design and build the Ulfberht, and what was its role in history? Now, Nova uses cutting edge science and old-fashioned detective work to reconstruct the Ulfberht and finally unravel the "Mystery of the Viking Sword."

Why Ships Sink (Episode #3911H)

KQED 9: Wed, Sep 18, 2013 -- 9:00 PM

Are you safe aboard a modern cruise ship? Twenty million passengers embark on cruises each year, vacationing in deluxe "floating cities" that offer everything from swimming pools to shopping malls to ice skating rinks. And the ships just keep getting bigger: The average cruise ship has doubled in size in just the last ten years. Some engineers fear that these towering behemoths are dangerously unstable, and the recent tragedy of the Costa Concordia has raised new questions about their safety. Now, NOVA brings together marine engineering and safety experts to reconstruct the events that led up to famous cruise disasters, including the ill-fated Concordia, the Sea Diamond, and the Oceanos. Are we really safe at sea-or are we on the brink of a 21st century Titanic?

Ground Zero Supertower (Episode #4016#)

KQED 9: Wed, Sep 11, 2013 -- 9:00 PM

Nova returns to Ground Zero to witness the final chapter in an epic story of engineering, innovation, and the perseverance of the human spirit: the completion of One World Trade Center, the skyscraper rising up 104 stories and 1,776 feet from the site where the Twin Towers once stood. In this update of Nova's "Engineering Ground Zero, " which featured behind-the-scenes access to the struggles of the engineers and architects working at 1 WTC and the National September 11 Memorial and Museum, Nova goes inside the construction of the new tower's final floors and the installation of its soaring, 800-ton spire and beacon. But 1 WTC isn't the only engineering marvel taking shape here: Nova goes underground to see the construction of a multi-billion dollar transit center whose sweeping, sinuous design is said to be inspired by the shape of a bird being released from a child's hand. Will the buildings be completed on time under competing business, environmental, and safety demands? And will the final product be a fitting site for national remembrance?

Making Stuff Smarter (Episode #3805H)

KQED Life: Fri, Sep 6, 2013 -- 3:00 AM

What can nature teach us about building smarter materials? Can we create materials that sense and respond? "When describing 'smart materials,' one analogy scientists give is the evolution from the first Terminator robot, a machine made of metal and circuitry, to the shape-shifting 'liquid guy' in Terminator 2," said Making Stuff producer Chris Schmidt. Smarter looks into the growing number of materials that almost seem alive - able to react, change and even learn. An Army tanker truck that heals its own bullet wounds. An airplane wing that changes shape as it flies. For inspirations and ideas, scientists are turning to nature and biology and producing some innovative new developments in materials science. Knowledge and inspiration drawn from nature are showing scientists new ways to give our materials amazing new abilities. By understanding how geckos climb even smooth walls, scientists have created a gecko adhesive that let's robots do the same. Studying the properties of skin has led to the development of self-healing protective foam. And Pogue literally goes swimming with sharks to understand a different kind of skin that is intriguing scientists. Scientists are modeling a material after sharkskin to develop an antibacterial film that, when sprayed in hospitals, could eliminate MRSA and other anti-biotic resistant bacteria. Pogue concludes "Smarter" with a visit to a scientist who has created a material that may make Harry potter's invisibility cloak a reality!

Making Stuff Cleaner (Episode #3804H)

KQED Life: Fri, Sep 6, 2013 -- 2:00 AM

Most modern materials are dangerous to the environment, but what about cleaning up our world? Batteries grown from viruses, tires made from orange peel oil, plastics made of sugar, and solar cells that cook up hydrogen-these are just a few glimpses of a new generation of clean materials that could power devices of the future. In Making Stuff Cleaner, David Pogue explores the rapidly developing science and business of clean energy and examines alternative ways to generate it, store it, and distribute it. Is hydrogen the way to go? One scientist is even using America's abundance of chicken feathers to create a cheap way to make hydrogen cars safer. What about lithium batteries? Does this solve an energy problem or create a new dependency - in this case, on South America for a different kind of limited resource than oil? Can scientists instead develop a process in which batteries run on molten salts found in cheap abundance in the US or on genetically engineered viruses? Pogue investigates the latest developments in biobased fuels and in harnessing solar energy for our cars, homes, and industry in a fascinating hour full of the "stuff" of a sustainable future.

3D Spies of WWII (Episode #3903)

KQED Life: Thu, Sep 5, 2013 -- 1:00 AM

During World War II, 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.

      Another station needs to do maintenance on its equipment on the tower on Monument Peak, requiring that we switch our DT54 Over the Air signal from the main antenna to the auxiliary when the work starts, then back to the main antenna at the conclusion. These switches should cause momentary outages only, and most receivers […]
