The Sounds Of Invisible Worlds
Like the microscope and the telescope did centuries ago, new technologies to capture and analyze sound are leading to startling discoveries about what the eyes cannot see.
More than 400 years ago in the small Dutch town of Middelburg, a father-and-son team stumbled on an invention that would one day change history, but which they dismissed as a dud. By tinkering with glass lenses, Hans and Zacharias Janssen invented the microscope. Yet this was not by design.
The Janssens were leaders in a new and highly lucrative industry: making reading glasses. In their quest for the perfect pair of spectacles, a highly sought-after luxury item, the Janssens discovered that they could magnify objects by aligning two lenses in a cylindrical tube. They were astounded to find that combining two lenses magnifies much more than any one lens does on its own. But the view was blurry and the device too clunky for their clients, so they put their quirky discovery aside.
