"The Lightness of Being" is a tour de force, revealing a universe where matter is the hum of strange music, mass doesn't weigh, and empty space is a multilayered, multicoloured superconductor. Physicists' understanding of the essential nature of reality changed radically over the past quarter century. And Frank Wilczek has played a lead role in establishing the new paradigms. Transcending the clash and mismatch of older ideas about what matter and space are, Wilczek presents some brilliant and clear syntheses. Extraordinarily readable and authoritative, "The Lightness of Being" is the first book to unwrap these exciting new ideas for the general public. Pointing to new directions where great discoveries in fundamental physics are likely, and providing a visionary context for the experiments in CERN, he envisions a new Golden Age in physics.
