The 1977 book A Pattern Language was a landmark in the design world, introducing a methodology that has become influential across many fields. Among them are software and “design patterns,” and important spinoff technologies like wiki (the basis of Wikipedia) and Agile Methodology. Yet curiously, the field where pattern methodology began – the built environment – has lagged conspicuously. As one remedy, a number of long-time collaborators with the original book’s lead author have f...

In this brief, accessible volume, the authors – an urban philosopher and a mathematician-physicist – explain the surprising new findings from the sciences that are beginning to transform environmental design in the modern era. Michael Mehaffy and Nikos Salingaros explore fractals, networks, self-organization, dynamical systems and other revolutionary ideas, describing them to non-science readers in a direct and engaging way. The book also examines fascinating new topics of design, includi...

All human-made structures are “incomplete,” according to author Michael Mehaffy – that is, they embody abstract information that necessarily leaves out essential aspects of reality. This important concept from mathematics and philosophy has new relevance for today’s human challenges, Mehaffy argues. For “incompleteness” need not be a problem – but we must understand its nature, and be prepared to work toward a “right adjustment of the process of abstraction,” in the words o...

Cities are experiencing a renaissance today, because we've begun to understand how they really work -- and how to make them work better for people.

This book is a lively, readable account of two revealing figures in the history of that renaissance: the urban economist Jane Jacobs and the architect Christopher Alexander. Their key insights have shaped several generations of scholars, professionals, and activists. However, as the book argues, this renaissance is still immature, and more must be...

Cities around the world are working to build more livable environments, better-quality public spaces, more resilient and sustainable urban economies, lower resource impacts, greater social equity, and other goals of a “new urban agenda.” In this process, the American movement advanced by the Congress for the New Urbanism has been unquestionably influential, if sometimes controversial. This volume presents a distillation of key essays by CNU proponents in their own words, as well as perspe...
