From genetics to cosmology to nanotechnology, science is on the brink of numerous and extraordinary mega-revolutions that will change the very nature of life.  Closer to Truth brings together leading scientists, scholars and artists to debate many of today’s fundamental issues. Joining host Robert Kuhn are astrophysicist Neil deGrasse Tyson; author/astronomer Timothy Ferris; evolutionary biologist Francisco Ayala; professor of neuroscience and philosophy Patricia Smith Churchland; and child psychologist Rochel Gelman. The panelists discuss the role of independent scientific study; how 'paradigms' work in science; and whether scientific discoveries are conditioned by the prevailing culture.
