<div><p>Quantum theory may be bizarre and inexplicable?but it's been shown to account for as much as 30 percent of American GDP, as this brilliant new book by science writer extraordinaire Brian Clegg reveals.</p><p>The Stone, Bronze, and Iron Ages, and the birth of steam machinery and electricity, saw human life transformed by new materials and technology. Clegg?who studied physics at Cambridge University and specializes in making the strangest aspects of the universe accessible to the general reader ?explores the Quantum Age, the revolution led by our understanding of the very, very small.</p><p>Atoms, electrons, and photons of light are all quantum particles, acting totally unlike the objects we experience. This weird quantum behavior lies at the heart of every electronic device and powers lasers in everything from DVDs to eye correction. It is also behind quantum biology, the astonishing new realization that biological functions, from our ability to see and photosynthesis in plants to the amazing ability of birds to navigate, rely directly on quantum effects.</p><p>We've all heard about how odd quantum theory is. But in this book, for the first time, Clegg reveals to a popular science audience precisely how <I>useful</I> it is. Incredible revelations along the way will thrill popular science fans and general readers alike.</p><p><B>Brian Clegg</B> is an acclaimed science writer published by Icon Books and St. Martin's Press. His books include <I>Inflight Science</I>, <I>Dice World</I> (forthcoming), <I>The Universe Inside You</I>, <I>Gravity</I>, and <I>Extra-Sensory</I>.</p><BR></div>
