NOVA Season 31 Full Episode Guide

Episode 15 - Hunt for the Supertwister
First Aired: March. 30,2004

Scientists, meteorologists and storm chasers try to uncover the secrets of F5 tornadoes, the largest, most powerful and most dangerous on Earth. Included are looks at how funnels form and the devastating 2003 tornado in Moore, Oklahoma, plus "tornado tourists," who pay companies to take them to the ferocious phenomena to see them first-hand.

Episode 14 - Life and Death in the War Zone
First Aired: March. 02,2004

While other reporters were embedded in fighting units during the Iraq War, NOVA was covering the emergency medical response, living night and day with the doctors, nurses, and medics in a frontline Combat Support Hospital (CSH). The program captures a period of the conflict in April and May of 2003 when CSH units faced a deluge of injured Iraqi soldiers and civilians who had little support from their country's collapsed health-care system.

Episode 11 - Dogs and More Dogs
First Aired: February. 03,2004

NOVA goes beyond the wagging tails and floppy ears to reveal surprising insights into the origin and evolutionary strategy of our canine companions. From a wolf research facility in rural Indiana to New York’s Westminster Dog Show, you’ll discover some amazing dog facts. Did you know the Saluki can beat any other mammal on earth in a three-mile race? That dogs developed spots for a specific reason? And that their evolution is helping us learn about our own?

Episode 9 - MARS Dead or Alive
Episode 5 - The Elegant Universe: Welcome to the 11th Dimension (3)
First Aired: November. 04,2003

Part 3 of "The Elegant Universe” with host Brian Greene shows how Edward Witten of Princeton's Institute for Advanced Study, aided by others, revolutionized string theory by successfully uniting the five different versions into a single theory that is cryptically named "M-theory," a development that requires a total of eleven dimensions. Ten...eleven...who's counting? But the new 11th dimension implies that strings can come in shapes called membranes, or "branes" for short. These have truly science fiction-like qualities, since in principle they can be as large as the universe. A brane can even be a universe—a parallel universe—and we may be living on one right now.

Episode 4 - The Elegant Universe: String's the Thing (2)
First Aired: October. 28,2003

Part 2, "String's the Thing," opens with a whimsical scene in a movie theater in which the history of the universe runs backwards to the Big Bang, the moment at which general relativity and quantum mechanics both came into play, and therefore the point at which our conventional model of reality breaks down. Then it's string theory to the rescue as Greene describes the steps that led from a forgotten 200-year-old mathematical formula to the first glimmerings of strings—quivering strands of energy whose different vibrations give rise to quarks, electrons, photons, and all other elementary particles. Strings are truly tiny, being smaller than an atom by the same factor that a tree is smaller than the solar system. But, as Greene explains, they are able to combine the laws of the large and the laws of the small into a proposal for a single, harmonious theory of everything.

Episode 3 - The Elegant Universe: Einstein's Dream (1)
First Aired: October. 28,2003

Part 1, "Einstein's Dream," introduces string theory and shows how modern physics—composed of two theories that are ferociously incompatible—reached its schizophrenic impasse: One theory, general relativity, successfully describes big things like stars and galaxies, while another, quantum mechanics, is equally successful at explaining small things like atoms and subatomic particles. Albert Einstein, the inventor of general relativity, dreamed of finding a single theory that would embrace all of nature's laws. But in this quest for the so-called unified theory, Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who've followed. That is, until the discovery of string theory.
