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.

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.
