Come and Take It: The Gun Printer's Guide to Thinking Free

by Cody Wilson

Cody Wilson, a self-described crypto-anarchist and rogue thinker, combines the controversial yet thrilling story of the production of the first ever 3D printable gun with a startling philosophical manifesto that gets to the heart of the twenty-first century debate over the freedom of information and ideas.Reminiscent of the classic Steal This Book by Abbie Hoffman, Cody Wilson has written a unique, critical, and philosophical guide through the digital revolution. Deflecting interference from the State Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives, the story of Defense Distributed--where Wilson's employees work against all odds to defend liberty and the right to access arms through the production of 3D printed firearms--takes us across continents, into dusty warehouses and high rise condominiums, through television studios, to the Texas desert, and beyond. Harkening to both Zen and the Art of Motorcycle Maintenance and The Anarchist Cookbook, Come and Take It follows a group of digital radicals as they navigate political subterfuge to create a technological miracle, against all odds. Combining elements of a modern-day thriller with a fascinating philosophical treatise, Wilson paints a scathing and timely portrait of an ideologically polarized America and his own struggle in the fight for liberty.

Cometography

by Gary W. David A. J. Kronk Maik Meyer Seargent

Cometography is a catalog of every comet observed throughout history. It is the most complete and comprehensive collection of data on comets available. Cometography comes in four sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides non-technical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet. In this way, Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

Along the way, the author presents general questions concerning the origin of terrestrial water and the molecular beginnings of lifeon Earth, as well as how the instruments used on a space mission like Rosetta can help answer them. The text concludes with a chapter on what scientists expect from the Rosetta mission and how its data will influence our life on Earth.As a result, the author elucidates highly topical and fascinating knowledge to scientists and students of various scientific backgrounds, allowing them to work with Rosetta's data.

Comets and How to Observe Them (Astronomers' Observing Guides)

by Richard Schmude Jr.

Comets have inspired wonder, excitement and even fear ever since they were first observed. But they are important members of the solar system, that contain material from early in the life of the system, held in deep-freeze. This makes them key in our understanding of the formation and evolution of many Solar System bodies. Recent ground- and space-based observations have changed much in our understanding of comets. Comets, and How to Observe Them gives a summary of our current knowledge and describes how amateur astronomers can contribute to the body of scientific knowledge of comets. This book contains many practical examples of how to construct comet light-curves, measure how fast a comet's coma expands, and determine the rotation period of the nucleus. All these examples are illustrated with drawings and photographs. Because of their unpredictable nature comets are always interesting and sometime spectacular objects to observe and image. The second part of the book therefore takes the reader through the key observing techniques that can be used with commercially available modern observing equipment, from basic observations to more scientific measurements.

Comets, Popular Culture, and the Birth of Modern Cosmology

by Sara Schechner

In a lively investigation into the boundaries between popular culture and early-modern science, Sara Schechner presents a case study that challenges the view that rationalism was at odds with popular belief in the development of scientific theories. Schechner Genuth delineates the evolution of people's understanding of comets, showing that until the seventeenth century, all members of society dreaded comets as heaven-sent portents of plague, flood, civil disorder, and other calamities. Although these beliefs became spurned as "vulgar superstitions" by the elite before the end of the century, she shows that they were nonetheless absorbed into the science of Newton and Halley, contributing to their theories in subtle yet profound ways. Schechner weaves together many strands of thought: views of comets as signs and causes of social and physical changes; vigilance toward monsters and prodigies as indicators of God's will; Christian eschatology; scientific interpretations of Scripture; astrological prognostication and political propaganda; and celestial mechanics and astrophysics. This exploration of the interplay between high and low beliefs about nature leads to the conclusion that popular and long-held views of comets as divine signs were not overturned by astronomical discoveries. Indeed, they became part of the foundation on which modern cosmology was built.

Comeuppance: Costly Signaling, Altruistic Punishment, and Other Biological Components of Fiction

by William Flesch

With Comeuppance, William Flesch delivers the freshest, most generous thinking about the novel since Walter Benjamin wrote on the storyteller and Wayne C. Booth on the rhetoric of fiction. In clear and engaging prose, Flesch integrates evolutionary psychology into literary studies, creating a new theory of fiction in which form and content flawlessly intermesh. Fiction, Flesch contends, gives us our most powerful way of making sense of the social world. Comeuppance begins with an exploration of the appeal of gossip and ends with an account of how we can think about characters and care about them as much as about persons we know to be real. We praise a storyteller who contrives a happy or at least an appropriate ending, and fault the writer who refuses us one. Flesch uses Darwinian theory to show how fiction satisfies our desire to see the good vindicated and the wicked get their comeuppance. He conveys the danger and excitement of reading fiction with nimble intelligence and provides wide reference to stories both familiar and little known. Flesch has given us a book that is sure to claim a central place in the discussion of literature and the humanities.

Comfortably Unaware: What We Choose To Eat Is Killing Us And Our Planet

by Richard Oppenlander

In Comfortably Unaware, Dr. Richard Oppenlander tackles the crucial issue of global depletion as it relates to food choice. We should all be committed, he tells us, to understanding the reality and consequences of our diet, the footprint it makes on our environment, and seek food products that are in the best interest of all living things. His forthright information and stark mental images are often disturbing-and that's how it should be. As the guardians of Planet Earth, we need to be shaken out of our complacency, to stop being comfortably unaware, and to understand the measures we must take to ensure the health and well-being of our planet-and of ourselves.

Coming Home to the Pleistocene

by Paul Shepard Florence R. Shepard

"When we grasp fully that the best expressions of our humanity were not invented by civilization but by cultures that preceded it, that the natural world is not only a set of constraints but of contexts within which we can more fully realize our dreams, we will be on the way to a long overdue reconciliation between opposites which are of our own making." --from Coming Home to the Pleistocene. Paul Shepard was one of the most profound and original thinkers of our time. Throughout his long and distinguished career, Paul Shepard returned repeatedly to his guiding theme, the central tenet of his thought: that our essential human nature is a product of our genetic heritage, formed through thousands of years of evolution during the Pleistocene epoch, and that the current subversion of that Pleistocene heritage lies at the heart of today's ecological and social ills. Coming Home to the Pleistocene provides the fullest explanation of that theme. Completed just before his death in the summer of 1996, it represents the culmination of Paul Shepard's life work and constitutes the clearest, most accessible expression of his ideas. Coming Home to the Pleistocene pulls together the threads of his vision, considers new research and thinking that expands his own ideas, and integrates material within a new matrix of scientific thought that both enriches his original insights and allows them to be considered in a broader context of current intellectual controversies. In addition, the book explicitly addresses the fundamental question raised by Paul Shepard's work: What can we do to recreate a life more in tune with our genetic roots? In this book, Paul Shepard presents concrete suggestions for fostering the kinds of ecological settings and cultural practices that are optimal for human health and well-being. Coming Home to the Pleistocene is a valuable book for those familiar with the life and work of Paul Shepard, as well as for new readers seeking an accessible introduction to and overview of his thought.

Coming to Our Senses: A Boy Who Learned to See, a Girl Who Learned to Hear, and How We All Discover the World

by Susan R. Barry

A neurobiologist reexamines the personal nature of perception in this groundbreaking guide to a new model for our senses.We think of perception as a passive, mechanical process, as if our eyes are cameras and our ears microphones. But as neurobiologist Susan R. Barry argues, perception is a deeply personal act. Our environments, our relationships, and our actions shape and reshape our senses throughout our lives.This idea is no more apparent than in the cases of people who gain senses as adults. Barry tells the stories of Liam McCoy, practically blind from birth, and Zohra Damji, born deaf, in the decade following surgeries that restored their senses. As Liam and Zohra learned entirely new ways of being, Barry discovered an entirely new model of the nature of perception. Coming to Our Senses is a celebration of human resilience and a powerful reminder that, before you can really understand other people, you must first recognize that their worlds are fundamentally different from your own.
