Acclaimed biologist Lewis Wolpert eloquently narrates the basics of human life through the lens of its smallest component: the cell. Everything about our existence— imagination and reproduction, birth and death—is governed by our cells. They are the basis of all life in the universe, from the tiniest of bacteria to the most complex of animals. Genes in developing embryos determine the makeup of individuals, and the rapid firing between nerve cells creates the spirit of who we are. When we age, our cells cannot repair the damage they have undergone; when we get ill, it is because cells are so damaged they stop working and die. In the tradition of Lewis Thomas’s science classic The Lives of a Cell, Wolpert, an internationally acclaimed embryologist, draws on the recent discoveries of genetics to demonstrate how human life derives from a single cell and then grows into a body: an incredibly complex society made up of billions of cells. Wolpert sensitively examines the science behind often controversial research topics that are much discussed by rarely understood—stem cell research, cloning, DNA, and mutating cancer cells—all the while illuminating how the intricacies of cellular behavior bear directly on human behavior. Wolpert isn’t afraid to tackle the tough questions, including how and why single cells evolved into complex organisms and, first and foremost, what gave rise to the original cell, the origin of all life. Lively and passionate, How We Live and Why We Die is both an accessible guide to understanding the human body and a deeply reverent meditation on life itself.
Cyber Spying Tracking Your Family's (Sometimes) Secret Online Lives shows everyday computer users how to become cyber-sleuths. It takes readers through the many different issues involved in spying on someone online. It begins with an explanation of reasons and ethics, covers the psychology of spying, describes computer and network basics, and takes readers step-by-step through many common online activities, and shows what can be done to compromise them. The book's final section describes personal privacy and counter-spy techniques. By teaching by both theory and example this book empowers readers to take charge of their computers and feel confident they can be aware of the different online activities their families engage in. Expert authors have worked at Fortune 500 companies, NASA, CIA, NSA and all reside now at Sytex, one of the largest government providers of IT services Targets an area that is not addressed by other books: black hat techniques for computer security at the personal computer level Targets a wide audience: personal computer users, specifically those interested in the online activities of their families
This book addresses the difficult conditions researchers may face in the field and provides lessons in how to navigate the various social, political, economic, health, and environmental challenges involved in fieldwork. It also sheds important light on aspects often considered "secret" or taboo. From anthropologists just starting out to those with over forty years in the field, these researchers offer the benefit of their experience conducting research in diverse cultures around the world. The contributions combine engaging personal narrative with consideration of theory and methods. The volume emphasizes how being adaptable, and aware, of the many risks and rewards of ethnographic research can help foster success in quantitative and qualitative data collection. This is a valuable resource for students of anthropological methods and those about to embark on fieldwork for the first time.
"The Secret Commonwealth is a guide to fairies, doppelgängers, wraiths, and other beings that its author Robert Kirk, an unusually inquisitive seventeenth-century Scottish minister, identifies as being ?of a middle nature betwixt man and angel.? Circulated in manuscript by its author, whose religious and scientific interests drew him at some genuine personal risk to investigate the hidden realities of the spiritual world, this short work was first published by Sir Walter Scott and then again in the late nineteenth century in an edition prepared by the famous collector of fairy tales, Andrew Lang, and dedicated to Robert Louis Stevenson. Nonetheless, Kirk’s work, which is a fine example of English prose, an important document in the history of ideas, and an enchanting introduction to fairy lore has remained a rarity"--Publisher description.

A primer on the underlying technologies that allow computer programs to work. Covers topics like computer hardware, combinatorial logic, sequential logic, computer architecture, computer anatomy, and Input/Output. Many coders are unfamiliar with the underlying technologies that make their programs run. But why should you care when your code appears to work? Because you want it to run well and not be riddled with hard-to-find bugs. You don't want to be in the news because your code had a security problem. Lots of technical detail is available online but it's not organized or collected into a convenient place. In The Secret Life of Programs, veteran engineer Jonathan E. Steinhart explores--in depth--the foundational concepts that underlie the machine. Subjects like computer hardware, how software behaves on hardware, as well as how people have solved problems using technology over time. You'll learn: How the real world is converted into a form that computers understand, like bits, logic, numbers, text, and colors The fundamental building blocks that make up a computer including logic gates, adders, decoders, registers, and memory Why designing programs to match computer hardware, especially memory, improves performance How programs are converted into machine language that computers understand How software building blocks are combined to create programs like web browsers Clever tricks for making programs more efficient, like loop invariance, strength reduction, and recursive subdivision The fundamentals of computer security and machine intelligence Project design, documentation, scheduling, portability, maintenance, and other practical programming realities. Learn what really happens when your code runs on the machine and you'll learn to craft better, more efficient code.
