Big Bang Machine (Episode #4201H)

KQED Plus: Tue, Apr 18, 2017 -- 11:00 AM

On July 4, 2012, scientists at the giant atom smashing facility at CERN announced the discovery of a subatomic particle that seems like a tantalizingly close match to the elusive Higgs Boson, thought to be responsible for giving all the stuff in the universe its mass. Since it was first proposed nearly fifty years ago, the Higgs has been the holy grail of particle physicists: if they can find it, it will validate the "standard model" that underlies all of modern physics. CERN's scientists are still scrutinizing the results from July to see how well they fit the Higgs prediction. If the data conceals surprises, they could upend much of what we thought we knew about the particles and forces that make up our universe.

Secrets of the Viking Sword (Episode #3913H)

KQED Life: Tue, Apr 11, 2017 -- 8:00 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 Life: Tue, Apr 4, 2017 -- 8:00 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?
