Physicists’ understanding of the essential nature of reality as changed radically over the past quarter century. Frank Wilczek, a 2004 Nobel Prize-winner in Physics, has played a lead role in establishing the new paradigms. His new book for the general public, The Lightness of Being, explores the concepts of space as a dynamic material and matter as a subtle pattern of disturbance in that material, and points the way towards where new discoveries in fundamental physics are likely to come.
