This book provides the first coherent account of the area of analysis that involves the Heisenberg group, quantization, the Weyl calculus, the metaplectic representation, wave packets, and related concepts. This circle of ideas comes principally from mathematical physics, partial differential equations, and Fourier analysis, and it illuminates all these subjects. The principal ...(展开全部)

Languages differ in how they describe space, and such differences between languages can be used to explore the relation between language and thought. This 2003 book shows that even in a core cognitive domain like spatial thinking, language influences how people think, memorize and reason about spatial relations and directions. After outlining a typology of spatial coordinate sy...(展开全部)

At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than ten trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredible, an interstellar spacecraft. Space explorers and planet-bound scientists alike p...(展开全部)
