“A Mystery: Why Can not We Walk Straight?” is an animated short on the very interesting question: Why can’t we walk straight? (If you don’t believe it, find a field, close your eyes and go!). A animated short film by Robert Krulwich on an animation by Benjamin Arthur.
“Try as you might, you can’t walk in a straight line without a visible guide point, like the Sun or a star. You might think you’re walking straight, but as NPR’s Robert Krulwich reports, a map of your route would reveal you are doomed to walk in circles.”
