Hear Adam Gopnik discuss his new book 'Winter', which introduces you to the artists, poets, composers, writers, explorers, scientists and thinkers who helped shape a new and modern idea of winter.

We learn how snow science leads to existential questions of God and our place in the world. Find out how the race to the poles marks the human drive to imprint meaning on a blank space.

'Winter' is a journey through the modern imagination, from the New Yorker writer and author of 'Paris to the Moon' and 'Through The Children's Gate'.
