Esta nueva edicion, que incluye nuevas imagenes, repasa toda la tradicion botanica y sus talentos, con una seleccion de las mejores obras de la Biblioteca Nacional de Viena. Desde manuscritos bizantinos hasta obras maestras del siglo XIX, a traves de peonias, lirios y crisantemos, estas exquisitas reproducciones deslumbran por su precision y su estetica. Sea con hojas cuidadosamente enrolladas, texturas de frutas dibujadas con precision o la belleza pura y la variedad de los colores, esta forma de arte es tan delicada como precisa, e incluso despierta nuestra conciencia sobre el entorno ecologico y sobre la preciosa flora natural tan amenazada.

An international team of over forty stratigraphic experts have helped to build the most up-to-date international stratigraphic framework for the Precambrian and Phanerozoic. This successor to A Geologic Time Scale 1989 by W. Brian Harland et al. (CUP 0521 387655) begins with an introduction to the theory and methodology behind the construction of the new time scale. The main part of the book is devoted to the scale itself, systematically presenting the standard subdivisions at all levels using a variety of correlation markers. Extensive use is made of isotope geochronology, geomathematics and orbital tuning to produce a standard geologic scale of unprecedented detail and accuracy with a full error analysis. A wallchart summarising the whole time scale, with paleogeographic reconstructions throughout the Phanerozoic, is included in the back of the book. The time scale will be an invaluable reference source for academic and professional researchers and students.

Bernie Krause é o mellor experto mundial en sons da natureza.Todo comezou co rumor do trigo nun campo de Kansas; dende entónten dedicado as últimas catro décadas a gravar paisaxes sonorasecolóxicas e os sons de mais de 15.000 especies nos lugares maisreconditos, salvaxes e virxes do planeta. A causa da depredacionhumana, a metade dos coros naturais que rexistrou xa non existen.Dende os sons imperceptibles dos virus ou o estrondo dos glaciarescrebados, ata o canto dos mamiferos mariños, neste libro fascinanteexpon os seus postulados sobre o son natural, dividido en tres tipos:a biofonia que producen animais e plantas; a xeofonia orixinadano vento, na auga e na chuvia e a partir da cal tribos remotasdesenvolveron escalas musicais; e a antrofonia resultado da accionhumana que, pola sua crecente influencia na natureza, ten efectosnegativos nas demais especies, como o varamento de baleas.

A comprehensive textbook covering modern quantum optics experiments, with emphasis on single-photon technology and quantum logic.

This is a stunningly illustrated journey through the spectacular wildlife of Spain, Portugal and Gibraltar. A Guide to Wild Spain, Portugal and Gibraltar is a unique book that brings together the history of exploration of the Iberian Peninsula in the 19th Century with the current state of its wild places and wildlife. The authors re-trace the footsteps taken by British naturalists based in Gibraltar and Jerez over a hundred years ago. They explore the length and breadth of the peninsula, from the Strait of Gibraltar in the south to the Pyrenees in the north. This exquisitely illustrated book is intended for all those with an interest in the natural history of Spain, Portugal and Gibraltar. It tells the reader where to go to find particular species and to witness natural phenomena like the migration of birds of prey. But it also tells how this has changed, often for the worse, but happily sometimes also for the better. In essence, this book is a 21st Century snapshot of one of Europe's ecologically richest lands.

Mathematical methods are essential tools for all physical scientists. This second edition provides a comprehensive tour of the mathematical knowledge and techniques that are needed by students in this area. In contrast to more traditional textbooks, all the material is presented in the form of problems. Within these problems the basic mathematical theory and its physical applications are well integrated. The mathematical insights that the student acquires are therefore driven by their physical insight. Topics that are covered include vector calculus, linear algebra, Fourier analysis, scale analysis, complex integration, Greens functions, normal modes, tensor calculus, and perturbation theory. The second edition contains new chapters on dimensional analysis, variational calculus, and the asymptotic evaluation of integrals. This book can be used by undergraduates, and lower-level graduate students in the physical sciences. It can serve as a stand-alone text, or as a source of problems and examples to complement other textbooks.
