Big Picture Science - Time for a Map

It’s hard to get lost these days. GPS pinpoints your location to within a few feet. Discover how our need to get from A to B holds clues about what makes us human, and what we lose now that every digital map puts us at the center.

Plus, stories of animal navigation: how a cat found her way home across Florida, and the magnetic navigation systems used by salmon and sea turtles.

Also, why you’ll soon be riding in driverless cars. And, how to map our universe.



You can listen to this and other episodes at, and be sure to check out Blog Picture Science, the companion blog to the radio show.
