141: Invisible Worlds
Oct 1, 1999
Stories of people who are trying to make invisible worlds visible, and what happens when you make them visible.
- Producer Nancy Updike tells the story of scientists who simply made up an invisible, weightless subatomic particle called the neutrino. Then they set out on the task of finding it, using tools that sound positively crude: A mineshaft and 100,000 gallons of dry cleaning fluid. (9 minutes)
