A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. As William McDonough and Michael Braungart argue in their provocative, visionary book, however, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world, they ask. In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, the authors make an exciting and viable case for change. Show more Show less

A history of mathematics from the cutting-edge of present-day research, this book tells the story of the most idiosyncratic and most fundamental numbers in pure mathematics, the primes. When counting, primes (numbers only divisible by one and themselves) appear without any reason or rhythm. To a non-mathematician this may seem an oddity. To scientists the key to this seeming randomness, called the Riemann Hypothesis, is one of the most important enigma within mathematics. The Riemann Hypothesis has significance beyond maths - it is the basis for all internet and e-commerce security and has been named as one of the questions of the 21st century, with a reward of a million US dollars to the person who can crack it. It also has ramifications within quantum mechanics, chaos theory and the future of computing. At the heart of the hypothesis is the study of prime numbers, the fundamental building blocks of mathematics. In The Music of the Primes , mathematician Matthew de Sautoy recounts the history of these elusive numbers, including the work of Euclid, Ramanujan, Odlyzko, the formation of RSA encryption, as well as reports first hand from the far reaches of today''s research.

Desde la aprobación de la Ley 16/2002 de Prevención y control integrados de la contaminación, la industria española se ha visto en la necesidad de afrontar cambios de carácter tecnológico (mejores técnicas), administrativo (nueva autorizacion ambiental integrada) y de gestion (transparencia informativa). Esta publicacion, elaborada con todo rigor tecnico, analiza exhaustivamente: - El origen legislativo de la Ley 16/2002. - Las principales novedades introducidas por la Ley 16/2002: autorizacion ambiental integrada, valores limites de emision, el Registro Estatal de Fuentes y Emisiones Contaminantes, el flujo de informacion que se deriva de ella. - Los dos principales modelos que sirven de base para la implantacion de sistemas de gestion medioambiental: UNE-EN ISO 14001:1996 y EMAS. - La interrelacion entre la Ley 16/2002 y los sistemas de gestion medioambiental. PREVENCION Y CONTROL INTEGRADOS DE CONTAMINACION desarrolla los siguientes apartados: - Directiva 96/61/CE relativa a la prevencion y control integrados de la contaminacion (IPPC) - Ley de prevencion y control integrados de la contaminacion - Ley 3/1998 de intervencion integral de la administracion ambiental - Sistemas de gestion medioambiental (SGMA): ISO 14001 y EMAS - Interrelacion de la Ley 16/2002 con los SGMA
