Expedition: Bismarck

In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District.

This documentary attempts to reconstruct the 24 August 79 AD eruption of Vesuvius hour by hour. By using the latest evidence from volcanology.

Twenty years after A Brief History of Time flummoxed the world with its big numbers and black holes, its author, Stephen Hawking, concedes that the "ultimate theory" he'd believed to be imminent - which would conclusively explain the origins of life, the universe and everything - remains frustratingly elusive. Yet despite his failing health and the seeming impossibility of the task, Hawking is still devoted to his work; an extraordinary drive that's captured here in fleeting interview snippets and footage of the scientist sharing a microwave dinner with some fawning PhD students. Though the pop-science tutorials that dapple the first of this two-part biography are winningly perky, Hawking, alas, remains as tricky to fathom as his boggling quantum whatnots

Over 100 years ago, Albert Einstein grappled with the implications of his revolutionary special theory of relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2. In "Einstein's Big Idea," NOVA dramatizes the remarkable story behind this equation. E = mc2 was just one of several extraordinary breakthroughs that Einstein made in 1905, including the completion of his special theory of relativity, his identification of proof that atoms exist, and his explanation of the nature of light, which would win him the Nobel Prize in Physics. Among Einstein's ideas, E = mc2 is by far the most famous. Yet how many people know what it really means? In a thought-provoking and engrossing docudrama, NOVA illuminates this deceptively simple formula by unraveling the story of how it came to be.

PBS' premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA demystifies science and technology, and highlights the people involved in scientific pursuits.

Could King Richard III's spinal deformity have prevented him from leading the charge at the Battle of Bosworth? Modern scoliosis sufferer Dominic Smee and a team of scientists and medieval warfare experts embark on an extraordinary journey to reveal new research that's changing our knowledge of a defamed medieval king.

David Hasselhoff, better known for his roles in “Knight Rider” and “Baywatch” released a song titled, “Looking for Freedom” the year before the Berlin Wall came down. He performed it on top of the Berlin Wall to a million people during the biggest New Year's Eve party Germany had ever seen. Twenty five years later, David revisits the now-reunited capital, investigating what is left of the Wall, and explores what it meant in the context of the Cold War dividing Communism in the East from democracy in the West. Along his journey he meets extraordinary people who dreamt of freedom and risked their lives trying to overcome the dreaded Berlin Wall.

Join Stephen Hawking and other renowned thinkers as they explore the revolutionary new ideas that have evolved since the publication of his blockbuster book. Besides interviews, this stimulating documentary uses computer graphics and simple, easy-to-understand demonstrations to explain complex concepts. Topics include black holes, string theory, supersymmetry, dimensions beyond our perception, and the mysterious M force; all potential keys to unlocking the elusive "theory of everything" that seems so tantalizingly close.
