This book provides a clear and mystery-free presentation of the central concepts in thermodynamics — probability, entropy, Helmholtz energy and Gibbs energy. It presents the concepts of entropy, free energy and various formulations of the Second Law in a friendly, simple language. It is devoid of all kinds of fancy and pompous statements made by authors of popular science books who write on this subject. The book focuses on the Four Laws of Thermodynamics. As it is said in the dedication page, this book is addressed to readers who might have already been exposed to Atkins' book having a similar title. It challenges both the title, and the contents of Atkins' book, Four Laws That Drive The Universe. One can glean from the title of this new book that the author's views are diametrically opposed to the views of Atkins. The book is addressed to any curious and intelligent reader. It aims to tickle, and hopefully to satisfy your curiosity. It also aims to challenge your gray matter, and to enrich your knowledge by telling you some facts and ideas regarding the Four Laws of Thermodynamics.

A Discover Best Science Book of the Year: “A fascinating, accurate and accessible account of some of [the] contemporary efforts to combat aging” (The New York Times). Los Angeles Times Book Prize Finalist Named a Best Book of the Year by the New York Times, San Jose Mercury News, and Library Journal An award-winning writer explores science’s boldest frontier—extension of the human life span—interviewing dozens of people involved in the quest to allow us to live longer, better lives. Delving into topics from cancer to stem cells to cloning, Merchants of Immortality looks at humankind’s quest for longevity and tackles profound questions about our hopes for defeating health problems like heart attacks, Parkinson’s disease, and diabetes. The story follows a close-knit but fractious band of scientists as well as entrepreneurs who work in the shadowy area between profit and the public good. The author tracks the science of aging back to the iconoclastic Leonard Hayflick—who was the first to show that cells age, and whose epic legal battles with the federal government cleared the path for today’s biotech visionaries. Among those is the charismatic Michael West, a former creationist who founded the first biotech company devoted to aging research. West has won both ardent admirers and committed foes in his relentless quest to promote stem cells, therapeutic cloning, and other technologies of “practical immortality.” Merchants of Immortality breathes scintillating life into the most momentous science of our day, assesses the political and bioethical controversies it has spawned, and explores its potentially dramatic effect on the length and quality of our lives. “Timely and engrossing . . . This is top-drawer journalism.” —Publishers Weekly, starred review “A carefully documented examination of how society deals with life-and-death matters.” —Kirkus Reviews, starred review “An important survey of the entire landscape of the science aimed at extending human life.” —Newsday “[This] highly readable and important book . . . provide[s] new insights into the intersection of science and politics.” —The Washington Post

Crick and Watson's discovery of the structure of DNA fifty years ago marked one of the great turning points in the history of science. Biology, immunology, medicine and genetics have all been radically transformed in the succeeding half-century, and the double helix has become an icon of our times. This fascinating exploration of a scientific phenomenon provides a lucid and engaging account of the background and context for the discovery, its significance and afterlife, while a series of essays by leading scientists, historians and commentators offers uniquely individual perspectives on DNA and its impact on modern science and society.

Understanding the history and philosophy of biological systematics (phylogenetics, taxonomy and classification of living things) is key to successful practice of the discipline. In this thoroughly revised Third Edition of the classic Biological Systematics, Andrew V. Z. Brower and Randall T. Schuh provide an updated account of cladistic principles and techniques, emphasizing their empirical and epistemological clarity. Brower and Schuh cover: -the history and philosophy of systematics -the mechanics and methods of character analysis, phylogenetic inference, and evaluation of results -the practical application of systematic results to: -biological classification -adaptation and coevolution -biodiversity, and conservation -new chapters on species and molecular clocks Biological Systematics is both a textbook for students studying systematic biology and a desk reference for practicing systematists. Part explication of concepts and methods, part exploration of the underlying epistemology of systematics, This third edition addresses why some methods are more empirically sound than others.
