PBS' premiere science series helps viewers of all ages explore the science behind the headlines. Along the way, it demystifies science and technology and highlights people involved in scientific pursuits.
Big Bang Machine (#4201H) Duration: 56:46 STEREO TVG
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 (#3913H) Duration: 56:46 STEREO TVPG
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 (#3911H) Duration: 56:46 STEREO TVPG
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?
Himalayan Megaquake (#4304H) Duration: 55:41 STEREO TVPG
Dramatic eyewitness footage reveals the shocking quake that rocked Nepal in April 2015. Join scientists as they examine why this earthquake was so devastating, how the victims are rebuilding and whether another earthquake looms on the horizon.
Holocaust Escape Tunnel (#4407H) Duration: 56:46 STEREO TV14-V
In the heart of Lithuania, a Holocaust secret lies buried. A team of archaeologists probes the ruins of a Nazi execution site to find the truth behind tales of a tunnel dug by desperate Jewish prisoners and their daring escape.
Escape from Nazi Alcatraz (#4112H) Duration: 56:46 STEREO TVPG
Colditz Castle, a notorious prisoner of war camp in Nazi Germany, was supposed to be escape-proof. But in the dark days at the end of World War II, a group of British officers dreamt up the ultimate escape plan: in a secret attic workshop, they constructed a two-man glider out of bed sheets and floorboards. Their plan was to fly to freedom from the roof of the castle, but the war ended before they could put it to the test. Now a crack team of aerospace engineers and carpenters rebuild the glider in the same attic using the same materials, and they'll do something the prisoners never got a chance to try: use a bathtub full of concrete to catapult the glider off the roof of the castle. As the hair-raising launch 90 feet up draws near, the program explores the Colditz legend and exposes the secrets of other ingenious and audacious escapes. Then, after a 70-year wait, the team finally finds out if the legendary glider plan would have succeeded.
Building Chernobyl's MegaTomb (#4408H) Duration: 56:46 STEREO TVPG
An international team of engineers races to construct a gargantuan dome to contain the lingering radioactive materials and crumbling remains of the Chernobyl nuclear reactor, decades after being the site of the world's worst nuclear disaster.
