Big Bang Machine (Episode #4201H)

KQED World: Fri, Mar 17, 2017 -- 5:00 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.

Why Ships Sink (Episode #3911H)

KQED World: Fri, Mar 10, 2017 -- 5:00 AM

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?
