Season 33 Episode 1 - Aired 9/20/2005
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.

Season 33 Episode 3 - Aired 10/11/2005
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.

Season 33 Episode 6 - Aired 11/15/2005
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.
