To the Best of Our Knowledge

PROMO       4/15/2007    "Frontiers of Physics"
*Tragedy struck Ron Mallett (Mal-et) when he was ten years old.  His
beloved father died and he wanted to bring him back.  So he dreamed of
building a time machine.  Ron Mallett grew up to become a theoretical
physicist.  Now he studies quantum mechanics and he's still trying to
figure out how to go back in time.  In this hour of To the Best of Our
Knowledge we'll talke about the physics of time travel and the debate
over why the universe is so finely-tuned for life

PROGRAM RUNDOWN:   "Frontiers of Physics"

0:01 - 19:41        SEGMENT 1: (19:42)
            Ron Mallett is a theoretical physicist and the author of
            "Time Traveler."  He tells Anne Strainchamps that he's
            been fascinated with the idea of time travel since his
            dad's early death. And he thinks he's found some clues in
            Einstein's work how he might try it, if not in this
            universe than in another. Also, Fleda Brown, poet
            laureate of Delaware reads some of her poems and talks
            with Steve Paulson.

            Wisconsin Public Radio producer Leo Duran reports on the
            science of movie and television science fiction.  He
            speaks with physicist Lawrence Krauss and screenwriter
            Michael Cassutt, and we hear lots of clips. Also, Chris
            Jones writes for Esquire Magazine and is also the author
            of "Too Far from Home."  He tells Jim Fleming what
            happened to the three astronauts left in space when the
            space shuttle Columbia was lost in 2003.

            Cosmologist Paul Davies talks with Steve Paulson about
            the anthropic principle and proposes that we live in a
            "participatory" universe - a premise he explores in his
            book, "Cosmic Jackpot."
