The theme of the present volume concerns people' s response to the natural environment, considered at scales varying from that of a house hold plant to that of vast wilderness areas. Our decision to focus on this particular segment of the physical environment was prompted in part by the intrinsic interest in this subject on the part of a diverse group of sodal scientists and professionals-and of laypersons, for that matter and in part by the relative neglect of this topic in standard treatments of the environment-behavior field. It also serves to bring out once again the interdisdplinary nature of that field, and we are pleased to have been able to inc1ude representatives from geography, sodology, soda! ecology, and natural recreation among our contributors. We believe that this volume will serve a useful purpose in helping to integrate the find ings and concepts in this presently somewhat fragmented field, scat tered as they are over a very diverse array of publications representing a similarly varied group of spedalties. It is hoped that the result will be to stimulate future development of this area and to add a measure of in creased coherence to it. Volume 7 of our series will be devoted to the theme of elderly people and the environment, with M. Powell Lawton joining us as guest co-editor.

Computer simulation has become an important means for obtaining knowledge about nature. The practice of scientific simulation and the frequent use of uncertain simulation results in public policy give rise to a wide range of philosophical questions. Referring to empirical results from science studies and political science, the author addresses the following philosophical questions: What specific types of uncertainty are associated with scientific simulation? What are the differences and similarities between simulation uncertainty and experimental uncertainty? What are appropriate ways to assess and communicate scientific simulation uncertainties in science-for-policy? One policy arena in which these questions figure most prominently is highlighted, that of anthropogenic climate change. Are humans currently changing the climate? Simulation results play a crucial role in the attribution of climate change to human influences. In this study, the specific types of uncertainty associated with this attribution are closely examined. The scientific knowledge about climate change enters the policymaking arena through the assessment reports produced every few years by the United Nations' Intergovernmental Panel on Climate Change (IPCC). The author participated as a 'philosophical observer' to the IPCC through the Dutch government delegation in order to obtain first-hand insights into how computer-simulation uncertainties are dealt with in such assessments. The final question addressed in this study is whether these uncertainties have been appropriately assessed and communicated in the Working Group I contribution to the Third Assessment Report of the IPCC (2001). The book is intended for a diverse audience of philosophers, natural and social scientists, and policy-makers. Book jacket.

This book is based on notes for the course Fractals:lntroduction, Basics and Perspectives given by MichaelF. Barnsley, RobertL. Devaney, Heinz-Otto Peit gen, Dietmar Saupe and Richard F. Voss. The course was chaired by Heinz-Otto Peitgen and was part of the SIGGRAPH '87 (Anaheim, California) course pro gram. Though the five chapters of this book have emerged from those courses we have tried to make this book a coherent and uniformly styled presentation as much as possible. It is the first book which discusses fractals solely from the point of view of computer graphics. Though fundamental concepts and algo rithms are not introduced and discussed in mathematical rigor we have made a serious attempt to justify and motivate wherever it appeared to be desirable. Ba sic algorithms are typically presented in pseudo-code or a description so close to code that a reader who is familiar with elementary computer graphics should find no problem to get started. Mandelbrot's fractal geometry provides both a description and a mathemat ical model for many of the seemingly complex forms and patterns in nature and the sciences. Fractals have blossomed enormously in the past few years and have helped reconnect pure mathematics research with both natural sciences and computing. Computer graphics has played an essential role both in its de velopment and rapidly growing popularity. Conversely, fractal geometry now plays an important role in the rendering, modelling and animation of natural phenomena and fantastic shapes in computer graphics.

Simulating for a crisis is far more than creating a simulation of a crisis situation. In order for a simulation to be useful during a crisis, it should be created within the space of a few days to allow decision makers to use it as quickly as possible. Furthermore, during a crisis the aim is not to optimize just one factor, but to balance various, interdependent aspects of life. In the COVID-19 crisis, decisions had to be made concerning e.g. whether to close schools and restaurants, and the (economic) consequences of a 3 or 4-week lock-down had to be considered. As such, rather than one simulation focusing on a very limited aspect, a framework allowing the simulation of several different scenarios focusing on different aspects of the crisis was required. Moreover, the results of the simulations needed to be easily understandable and explainable: if a simulation indicates that closing schools has no effect, this can only be used if the decision makers can explain why this is the case. This book describes how a simulation framework was created for the COVID-19 crisis, and demonstrates how it was used to simulate a wide range of scenarios that were relevant for decision makers at the time. It also discusses the usefulness of the approach, and explains the decisions that had to be made along the way as well as the trade-offs. Lastly, the book examines the lessons learned and the directions for the further development of social simulation frameworks to make them better suited to crisis situations, and to foster a more resilient society.

This book addresses key conceptual issues relating to the modern scientific and engineering use of computer simulations. It analyses a broad set of questions, from the nature of computer simulations to their epistemological power, including the many scientific, social and ethics implications of using computer simulations. The book is written in an easily accessible narrative, one that weaves together philosophical questions and scientific technicalities. It will thus appeal equally to all academic scientists, engineers, and researchers in industry interested in questions (and conceivable answers) related to the general practice of computer simulations.

Silicon Second Nature takes us on an expedition into an extraordinary world where nature is made of bits and bytes and life is born from sequences of zeroes and ones. Artificial Life is the brainchild of scientists who view self-replicating computer programs—such as computer viruses—as new forms of life. Anthropologist Stefan Helmreich's look at the social and simulated worlds of Artificial Life—primarily at the Santa Fe Institute, a well-known center for studies in the sciences of complexity—introduces readers to the people and programs connected with this unusual hybrid of computer science and biology. When biology becomes an information science, when DNA is downloaded into virtual reality, new ways of imagining "life" become possible. Through detailed dissections of the artifacts of Artifical Life, Helmreich explores how these novel visions of life are recombining with the most traditional tales told by Western culture. Because Artificial Life scientists tend to see themselves as masculine gods of their cyberspace creations, as digital Darwins exploring frontiers filled with primitive creatures, their programs reflect prevalent representations of gender, kinship, and race, and repeat origin stories most familiar from mythical and religious narratives. But Artificial Life does not, Helmreich says, simply reproduce old stories in new software. Much like contemporary activities of cloning, cryonics, and transgenics, the practice of simulating and synthesizing life in silico challenges and multiplies the very definition of vitality. Are these models, as some would claim, actually another form of the real thing? Silicon Second Nature takes Artifical Life as a symptom and source of our mutating visions of life itself.
