NOVA: Season 33 - 20 Episode s

33x1 - Mystery of the Megaflood
September 20, 2005
It was the greatest flood of the past two million years, and it posed a giant scientific riddle. A maverick geologist became convinced that thousand-foot-deep floodwaters had scoured out vast areas of the American northwest near the end of the last ice age. Mainstream scientists scorned his theory while he searched patiently for answers to what could have triggered such an inconceivably violent event. Finally, an ingenious solution silenced the skeptics: traces of an enormous ice dam half a mile high, which had blocked a valley in present-day Montana and created an enormous lake behind it. With the help of stunningly realistic animation, NOVA takes viewers back to the Ice Age to reveal what happened when the dam broke, unleashing a titanic flood that swept herds of woolly mammoth and everything else into oblivion.
33x2 - Sinking the Supership
October 4, 2005
The search for the wreck of the Yamato, the largest and mightiest battleship ever floated and the pride of the Japanese Imperial Fleet. Constructed in absolute secrecy and sunk by American planes toward the end of World War II, her rapid demise had been a mystery, rather like a military Titanic.
33x3 - Einstein's Big Idea
October 11, 2005
Exactly 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. 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 documentary, Einstein's Big Idea illuminates this deceptively simple formula by unrevealing the story of how it came to be.
33x4 - Volcano Under the City
November 1, 2005
A restless mountain threatens a bustling metropolis perched on its flanks.
33x5 - Hitler's Sunken Secret
November 8, 2005
One of the most daring clandestine operations of World War II was the 1944 sinking of the Norwegian ferry Hydro with its cargo of "heavy water" destined for the Nazis' secret atomic bomb project. Although the mission was declared a success, no one ever established if the special shipment was actually on board. In this program, NOVA descends 1,300 feet beneath a remote Norwegian lake to find the answer.
33x6 - Newton's Dark Secrets
November 15, 2005
He was the greatest scientist of his day, perhaps of all time. But while Isaac Newton was busy discovering the universal law of gravitation, he was also searching out hidden meanings in the Bible and pursuing the covert art of alchemy. In this program, NOVA explores the strange and complex mind of Isaac Newton. Using docudrama scenes starring Scott Handy (Masterpiece Theatre's Henry VIII) as Newton, this film recreates the unique climate of late 17th-century England, where a newfound fascination with science and mathematics coexisted with extreme views on religious doctrine. Newton shared both obsessions.
33x7 - Storm That Drowned a City
November 22, 2005
In less than 12 hours on August 29, 2005, Hurricane Katrina devastated the Louisiana coast, leading to more than a thousand deaths and transforming a city of over one million into an uninhabitable swamp. NOVA investigates the science of Hurricane Katrina, combining a penetrating analysis of what went wrong with a dramatic, minute-by-minute unfolding of events told through eyewitness testimony. What made this storm so deadly? Will powerful hurricanes like Katrina strike more often? How accurately did scientists predict its impact, and why did the levees protecting New Orleans fail?

November 14, 2006
This episode focuses on a scientific debate about five siblings in a Turkish family who walk on all fours. When, in 2005, scientist Uner Tan labeled them "genetic throwbacks," they became part of the dialogue about a possible missing link to an era when humans walked on all fours. Included: comments from geneticist Sean Carroll and anthropologist Brian Richmond, who disagree with Tan; and interviews with and footage of the family.
