Are Walter’s actions really helping his planet along the road to destruction, or is it all just a dream? Chris Van Allsburg’s classic ...(展开全部)

What can happen in just a second, a minute, or an hour? How can we measure time? The flap of a vulture's wing. A crocodile's heartbeat. The weight of a baby blue whale. The life of a mayfly. These increments of time may sound a bit strange, but they are all fascinating ways in which we can think about time. But what exactly is time? In "Just a Second", the award-winning author-...(展开全部)

Describing the physical properties of quantum materials near critical points with long-range many-body quantum entanglement, this book introduces readers to the basic theory of quantum phases, their phase transitions and their observable properties. This second edition begins with a new section suitable for an introductory course on quantum phase transitions, assuming no prior ...(展开全部)

Quantum Phase Transitions details the fundamental changes that can occur in the macroscopic nature of matter at zero temperature due to small variations in a given external parameter. The author develops the theory of quantum phase transitions in the simplest possible class of nondisordered, interacting systems--the quantum Ising and rotor models. He pays particular attention t...(展开全部)
