**Theoretical physicist Carlo Rovelli is best known among physicists for his work on loop quantum gravity, a mathematical theory that quantizes spacetime (see the article by Martin Bojowald, Physics Today, March 2013, page 35). His broader appeal comes from his book Seven Brief Lessons on Physics, which introduced general audiences to the physics of black holes, general relativity, and quantum mechanics.**

**In his latest book, The Order of Time, Rovelli explores what he calls “perhaps the greatest remaining mystery” in physics: the nature of time. “Why do we remember the past and not the future?” he asks. “What does it really mean to say that time ‘passes’? . . . What am I listening to when I listen to the passing of time?”**
