Greg Chaitin, author most recently of MetaMath!, discusses the ubiquity of undecidability: incredibly all kinds of mathematical and physical systems exhibit utterly unpredictable, baffling behavior– and it’s possible to *prove* we can never fully understand why!

Quick interviews with folks here at the Gathering For Gardner, including Stephen Wolfram, Will Shortz, Dale Seymour, John Conway and many others.

The world’s largest ever exhibit of Escher’s works is on display, right now, at the Boca Raton Musuem of Art If you can, this is a must see event! We talk with the collector, Rock J. Walker about his fascination with this amazing work.

And of course we answer last week’s puzzle, and hear from listeners!

Kyle and Chaim get into trouble with their wives and Mathfactor correspondent, Stephen Morris, discusses the Kate Bush Conjecture and And The Clocks Struck Thirteen
