The Parsimonious Universe

Why does nature prefer some shapes and not others? The variety of sizes, shapes, and irregularities in nature is endless. Skillfully integrating striking full-color illustrations, the authors describe the efforts by scientists and mathematicians since the Renaissance to identify and describe the principles underlying the shape of natural forms. But can one set of laws account for both the symmetry and irregularity as well as the infinite variety of nature's designs? A complete answer to this question is likely never to be discovered. Yet, it is fascinating to see how the search for some simple universal laws down through the ages has increased our understanding of nature. The Parsimonious Universe looks at examples from the world around us at a non-mathematical, non-technical level to show that nature achieves efficiency by being stingy with the energy it expends.

Many properties of minimal surfaces are of a global nature, and this is already true for the results treated in the first two volumes of the treatise. Part I of the present book can be viewed as an extension of these results. For instance, the first two chapters deal with existence, regularity and uniqueness theorems for minimal surfaces with partially free boundaries. Here one of the main features is the possibility of "edge-crawling" along free parts of the boundary. The third chapter deals with a priori estimates for minimal surfaces in higher dimensions and for minimizers of singular integrals related to the area functional. In particular, far reaching Bernstein theorems are derived. The second part of the book contains what one might justly call a "global theory of minimal surfaces" as envisioned by Smale. First, the Douglas problem is treated anew by using Teichmüller theory. Secondly, various index theorems for minimal theorems are derived, and their consequences for the space of solutions to Plateau ́s problem are discussed. Finally, a topological approach to minimal surfaces via Fredholm vector fields in the spirit of Smale is presented.

Inside PFTB ("Proofs from The Book") is indeed a glimpse of mathematical heaven, where clever insights and beautiful ideas combine in astonishing and glorious ways. Some of the proofs are classics, but many are new and brilliant proofs of classical results--"Notices of the AMS," August 1999.

Challenging historic assumptions about human relationships with nature, Jan G. Laitos examines how environmental laws have addressed environmental problems in the past, and the reasons for the laws' inability to successfully prevent environmental contamination and alterations of critical environmental systems. This forward-thinking book offers a creative and organic alternative to traditional but ultimately unsuccessful environmental rules. It explains the need for a new generation of environmental laws grounded in the universal laws of nature which might succeed where past and current approaches have largely failed.

Maps were at the heart of cultural life in the Americas from before colonization to the formation of modern nation-states. The fourteen essays in Early American Cartographies examine indigenous and European peoples' creation and use of maps to better represent and understand the world they inhabited. Drawing from both current historical interpretations and new interdisciplinary perspectives, this collection provides diverse approaches to understanding the multilayered exchanges that went into creating cartographic knowledge in and about the Americas. In the introduction, editor Martin Bruckner provides a critical assessment of the concept of cartography and of the historiography of maps. The individual essays, then, range widely over space and place, from the imperial reach of Iberian and British cartography to indigenous conceptualizations, including "dirty," ephemeral maps and star charts, to demonstrate that pre-nineteenth-century American cartography was at once a multiform and multicultural affair. This volume not only highlights the collaborative genesis of cartographic knowledge about the early Americas; the essays also bring to light original archives and innovative methodologies for investigating spatial relations among peoples in the western hemisphere. Taken together, the authors reveal the roles of early American cartographies in shaping popular notions of national space, informing visual perception, animating literary imagination, and structuring the political history of Anglo- and Ibero-America.

This book is about value, about the value of a car you want to buy, a workbench you decide to make, or a house you want to sell. It will be of interest to those industrial managers who must increase gross margins despite higher wages and material costs and to design engineers, buyers, cost accountants, quality specialists, industrial engineers, and those men in Marketing and Finance who have their fingers on the pulse of a product value.
