On this edition of our program, we speak with Ian Scheffler, who has written for The New Yorker, The Guardian, The Los Angeles Times, and The Los Angeles Review of Books. His first book, just out, is a nonfiction text called "Cracking the Cube: Going Slow to Go Fast and Other Unexpected Turns in the World of Competitive Rubik's Cube Solving." As one Erno Rubik -- the inventor of the famous cube -- has noted of this book: "Scheffler provides the first comprehensive book on the global phenomenon of speedcubing. Much has changed since the first world championship was organized in Budapest in 1982. But the emotions were all there already -- good to see they haven't cooled in over three decades. The cubing community is growing ever larger, younger -- and faster!"
