"Roald Hoffmann's contributions to chemistry are well known; this Nobel laureate has published more than 500 articles and two books. As an "applied theoretical chemist," he has made significant contributions to our understanding of chemical bonding and reactivity, and taught two generations of chemists how to use molecular orbitals for real chemistry. Less well known, however, are Hoffmann's important and insightful contributions to the areas of scholarship surrounding chemistry. Over a career that spans nearly fifty years, Roald Hoffmann has thought and written copiously about the broader context of chemistry and its relationship to the arts and poetry. This book contains Hoffmann's essays and is organized around several major themes: chemical reasoning and explanation, writing and communicating in science, ethics, art and science, and chemical education. A few are unpublished lectures that are valuable additions to the volume. The editors have the full cooperation of Roald Hoffmann in this project. Most of the published work will be reprinted verbatim, but a few of the essays will be revised to eliminate redundancy. The unpublished lectures will also be edited since they were originally intended to be delivered orally at specific occasions. The editors will provide an introduction to the book, and some introductory material for each section. In introducing the material, they will highlight the intrinsic importance and interest of the ideas, as well as the places where Hoffmann's thought makes novel contributions to cognate areas"--

"Bioart is a new art form that has emerged from the cultural impact and increasing accessibilty of contemporary biotechnology. Signs of Life is the first book to focus exclusively on art that uses biotechnology as its medium, defining and discussing the theoretical and historical implications of bio art and offering examples of work by prominent artists. Bio art manipulates the processes of life; in its most radical form, it invents or transforms living organisms. It is not representational; bio art is in vivo. (A celebrated example is Eduardo Kac's own GFP Bunny, centered on Alba, the transgenic green rabbit.) The creations of bio art become a part of evolution and, provided they are capable of reproduction, can last as long as life exists on earth. Thus, bio art raises unprecedented questions about the future of life, evolution, society, and art. The contibutions to Signs of Life articulate the critical theory of bio art and documents its fundamental works. The writers - who include such prominent scholars as Barbara Maria Stafford, Eugene Thacker, and Dorothy Nelkin - consider the culture and aesthetics of biotechnology, the ethical and philosophical aspects of bio art, and biology in art history. The section devoted to artworks and artists including George Gessert's "Why I Breed Plants," Oron Catts and Ionat Zurr's "Semi-Living Art," Marc Quinn's "Genomic Portrait," and Heather Ackroyd and Dan Harvey's "Chlorophyll Apparitions.". --
