The Known Unknowns: Marcelo Gleiser Explains The Limits of Understanding

Searching for understanding on Burton Island.

To wonder about the world around us is an essential part of being human. “We are that very rare aggregate of molecules that is able to ask questions about our existence and about the universe,” says physicist Marcelo Gleiser.

He contends that our quest for scientific understanding is like an island of knowledge: the more we know, the larger the island grows, but as the island grows, so too does the shoreline. The limits of our understanding increase even as our comprehension grows.

We talk to Marcelo Gleiser, Professor of Physics and Astronomy at Dartmouth College, about the history of the scientific quest for understanding and about his new book The Island of Knowledge.

Also in the program, we continue our series of campaign interviews with major party challengers for the state's top offices. Dean Corren is a Progressive who's says his motivation to run for lieutenant governor is rooted in his support for single-payer, universal health care.
