In Book Oneof this four-volume work, Alexander describes a scientific view of the world in which all space-matter has perceptible degrees of life, and establishes this understanding of living structures as an intellectual basis for a new architecture. He identifies fifteen geometric properties which tend to accompany the presence of life in nature, and also in the buildings and cities we make. These properties are seen over and over in nature and in the cities and streets of the past, but they have almost disappeared in the impersonal developments and buildings of the last hundred years. This book shows that living structures depend on features which make a close connection with the human self, and that only living structure has the capacity to support human well-being.

Christopher Alexander's series of groundbreaking books--including The Timeless Way of Building and A Pattern Language--have illuminated the fundamental truths of traditional ways of building, revealing what gives life and beauty and true functionality to buildings and towns. Now, in The Nature of Order, Alexander delves into the essential properties of life itself, highlighting a common set of well-defined structures that he believes are present in all order--and in all life--from micro-organisms and mountain ranges to the creation of good houses and vibrant communities. In The Phenomenon of Life, the first volume in this masterwork, Alexander ponders the nature of order as an intellectual basis for a new architecture, proposing a well-defined scientific view of the world in which all space-matter has perceptible degrees of life. With this view as foundation, we can ask precise questions about what must be done to create life in the world--"whether in a single room...a doorknob...a neighborhood...even in a vast region." He presents the basic tenets of the concept, expanding on his theories of centers and of wholeness as a structure, and describes the fifteen properties from which he feels wholeness may be built. He also argues that living structure is at once both personal and structural, related not only to the geometry of space and how things work, but to human beings whose lives are ultimately based on feeling. Thus order, as the foundation of all things and as the foundation of all architecture, is both rooted in substance and rooted in feeling. Here then is the culmination of decades of intense thinking by one of the most innovative architects alive.

In this groundbreaking book, Adrian Bejan takes the recurring patterns in nature—trees, tributaries, air passages, neural networks, and lightning bolts—and reveals how a single principle of physics, the constructal law, accounts for the evolution of these and many other designs in our world. Everything—from biological life to inanimate systems—generates shape and structure and evolves in a sequence of ever-improving designs in order to facilitate flow. River basins, cardiovascular systems, and bolts of lightning are very efficient flow systems to move a current—of water, blood, or electricity. Likewise, the more complex architecture of animals evolve to cover greater distance per unit of useful energy, or increase their flow across the land. Such designs also appear in human organizations, like the hierarchical “flowcharts” or reporting structures in corporations and political bodies. All are governed by the same principle, known as the constructal law, and configure and reconfigure themselves over time to flow more efficiently. Written in an easy style that achieves clarity without sacrificing complexity, Design in Nature is a paradigm-shifting book that will fundamentally transform our understanding of the world around us.

The venerable cities of the past, such as Venice or Amsterdam, convey a feeling of wholeness, an organic unity that surfaces in every detail, large and small, in restaurants, shops, public gardens, even in balconies and ornaments. But this sense of wholeness is lacking in modern urban design, with architects absorbed in problems of individual structures, and city planners preoccupied with local ordinances, it is almost impossible to achieve. In this groundbreaking volume, architect and planner Christopher Alexander presents a new theory of urban design which attempts to recapture the process by which cities develop organically. To discover the kinds of laws needed to create a growing whole in a city, Alexander proposes here a preliminary set of seven rules which embody the process at a practical level and which are consistent with the day-to-day demands of urban development. He then puts these rules to the test, setting out with a number of his graduate students to simulate the urban redesign of a high-density part of San Francisco, initiating a project that encompassed some ninety different design problems, including warehouses, hotels, fishing piers, a music hall, and a public square. This extensive experiment is documented project by project, with detailed discussion of how each project satisfied the seven rules, accompanied by floorplans, elevations, street grids, axonometric diagrams and photographs of the scaled-down model which clearly illustrate the discussion. A New Theory of Urban Design provides an entirely new theoretical framework for the discussion of urban problems, one that goes far to remedy the defects which cities have today.

"These notes are about the process of design: the process of inventing things which display new physical order, organization, form, in response to function." This book, opening with these words, presents an entirely new theory of the process of design. In the first part of the book, Christopher Alexander discusses the process by which a form is adapted to the context of human needs and demands that has called it into being. He shows that such an adaptive process will be successful only if it proceeds piecemeal instead of all at once. It is for this reason that forms from traditional un-self-conscious cultures, molded not by designers but by the slow pattern of changes within tradition, are so beautifully organized and adapted. When the designer, in our own self-conscious culture, is called on to create a form that is adapted to its context he is unsuccessful, because the preconceived categories out of which he builds his picture of the problem do not correspond to the inherent components of the problem, and therefore lead only to the arbitrariness, willfulness, and lack of understanding which plague the design of modern buildings and modern cities. In the second part, Mr. Alexander presents a method by which the designer may bring his full creative imagination into play, and yet avoid the traps of irrelevant preconception. He shows that, whenever a problem is stated, it is possible to ignore existing concepts and to create new concepts, out of the structure of the problem itself, which do correspond correctly to what he calls the subsystems of the adaptive process. By treating each of these subsystems as a separate subproblem, the designer can translate the new concepts into form. The form, because of the process, will be well-adapted to its context, non-arbitrary, and correct. The mathematics underlying this method, based mainly on set theory, is fully developed in a long appendix. Another appendix demonstrates the application of the method to the design of an Indian village.

"If you ever wondered about the repeated number sequences you see and what they might be trying to tell you, Jones and Flaxman take you on a rollercoaster ride through the levels of mind and consciousness." - Chellie Campbell, author The Wealthy Spirit and Zero to Zillionaire Do you wake up every night and see 11:11 on the clock? Or 3:33? 4:44? Does the same number sequence seem to appear throughout your life over and over? Did you know that millions of people all over the world experience the same phenomenon? These mysterious number sequences are known as "time prompts," and show up on digital clocks, cell phones, receipts, billboards, advertisements, and other places. They seem like pure coincidence, but what if they are actually messages from a higher source, like angels, guides, or even the Universe itself, urging you to pay attention to something important? This book explores the many theories about what these number sequences are, including: The science behind synchronicities, coincidences, and the mathematical nature of reality Numerical patterns and sacred geometry in nature - such as the Fibonacci spiral, the golden ratio, and DNA sequences Enter the intriguing world of time prompts. If numbers are the language of the Universe, what are they saying to you?
