| alpha gel switch mechanical pencil: Blindsight Peter Watts, 2006-10-03 Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied. |

A smart, funny, gorgeous retelling starring all characters of color. Zuri Benitez has pride. Brooklyn pride, family pride, and pride in her Afro-Latino roots. But pride might not be enough to save her rapidly gentrifying neighborhood from becoming unrecognizable. When the wealthy Darcy family moves in across the street, Zuri wants nothing to do with their two teenage sons, even as her older sister, Janae, starts to fall for the charming Ainsley. She especially can’t stand the judgmental and arrogant Darius. Yet as Zuri and Darius are forced to find common ground, their initial dislike shifts into an unexpected understanding. But with four wild sisters pulling her in different directions, cute boy Warren vying for her attention, and college applications hovering on the horizon, Zuri fights to find her place in Bushwick’s changing landscape, or lose it all. Zoboi skillfully depicts the vicissitudes of teenage relationships, and Zuri’s outsize pride and poetic sensibility make her a sympathetic teenager in a contemporary story about race, gentrification, and young love.

| alpha gel switch mechanical pencil: The 71F Advantage National Defense University Press, 2010-09 Includes a foreword by Major General David A. Rubenstein. From the editor: 71F, or 71 Foxtrot, is the AOC (area of concentration) code assigned by the U.S. Army to the specialty of Research Psychology. Qualifying as an Army research psychologist requires, first of all, a Ph.D. from a research (not clinical) intensive graduate psychology program. Due to their advanced education, research psychologists receive a direct commission as Army officers in the Medical Service Corps at the rank of captain. In terms of numbers, the 71F AOC is a small one, with only 25 to 30 officers serving in any given year. However, the 71F impact is much bigger than this small cadre suggests. Army research psychologists apply their extensive training and expertise in the science of psychology and social behavior toward understanding, preserving, and enhancing the health, well being, morale, and performance of Soldiers and military families. As is clear throughout the pages of this book, they do this in many ways and in many areas, but always with a scientific approach. This is the 71F advantage: applying the science of psychology to understand the human dimension, and developing programs, policies, and products to benefit the person in military operations. This book grew out of the April 2008 biennial conference of U.S. Army Research Psychologists, held in Bethesda, Maryland. This meeting was to be my last as Consultant to the Surgeon General for Research Psychology, and I thought it would be a good idea to publish proceedings, which had not been done before. As Consultant, I'd often wished for such a document to help explain to people what it is that Army Research Psychologists do for a living. In addition to our core group of 71Fs, at the Bethesda 2008 meeting we had several brand-new members, and a number of distinguished retirees, the grey-beards of the 71F clan. Together with longtime 71F colleagues Ross Pastel and Mark Vaitkus, I also saw an unusual opportunity to capture some of the history of the Army Research Psychology specialty while providing a representative sample of current 71F research and activities. It seemed to us especially important to do this at a time when the operational demands on the Army and the total force were reaching unprecedented levels, with no sign of easing, and with the Army in turn relying more heavily on research psychology to inform its programs for protecting the health, well being, and performance of Soldiers and their families. |

| alpha gel switch mechanical pencil: The Emperor of All Maladies Siddhartha Mukherjee, 2011-08-09 Winner of the Pulitzer Prize and a documentary from Ken Burns on PBS, this New York Times bestseller is “an extraordinary achievement” (The New Yorker)—a magnificent, profoundly humane “biography” of cancer—from its first documented appearances thousands of years ago through the epic battles in the twentieth century to cure, control, and conquer it to a radical new understanding of its essence. Physician, researcher, and award-winning science writer, Siddhartha Mukherjee examines cancer with a cellular biologist’s precision, a historian’s perspective, and a biographer’s passion. The result is an astonishingly lucid and eloquent chronicle of a disease humans have lived with—and perished from—for more than five thousand years. The story of cancer is a story of human ingenuity, resilience, and perseverance, but also of hubris, paternalism, and misperception. Mukherjee recounts centuries of discoveries, setbacks, victories, and deaths, told through the eyes of his predecessors and peers, training their wits against an infinitely resourceful adversary that, just three decades ago, was thought to be easily vanquished in an all-out “war against cancer.” The book reads like a literary thriller with cancer as the protagonist. Riveting, urgent, and surprising, The Emperor of All Maladies provides a fascinating glimpse into the future of cancer treatments. It is an illuminating book that provides hope and clarity to those seeking to demystify cancer. |

| alpha gel switch mechanical pencil: The Well-Educated Mind: A Guide to the Classical Education You Never Had (Updated and Expanded) Susan Wise Bauer, 2015-11-16 The enduring and engaging guide to educating yourself in the classical tradition. Have you lost the art of reading for pleasure? Are there books you know you should read but haven’t because they seem too daunting? In The Well-Educated Mind, Susan Wise Bauer provides a welcome and encouraging antidote to the distractions of our age, electronic and otherwise. Newly expanded and updated to include standout works from the twenty-first century as well as essential readings in science (from the earliest works of Hippocrates to the discovery of the asteroid that killed the dinosaurs), The Well-Educated Mind offers brief, entertaining histories of six literary genres—fiction, autobiography, history, drama, poetry, and science—accompanied by detailed instructions on how to read each type. The annotated lists at the end of each chapter—ranging from Cervantes to Cormac McCarthy, Herodotus to Laurel Thatcher Ulrich, Aristotle to Stephen Hawking—preview recommended reading and encourage readers to make vital connections between ancient traditions and contemporary writing. The Well-Educated Mind reassures those readers who worry that they read too slowly or with below-average comprehension. If you can understand a daily newspaper, there’s no reason you can’t read and enjoy Shakespeare’s sonnets or Jane Eyre. But no one should attempt to read the “Great Books” without a guide and a plan. Bauer will show you how to allocate time to reading on a regular basis; how to master difficult arguments; how to make personal and literary judgments about what you read; how to appreciate the resonant links among texts within a genre—what does Anna Karenina owe to Madame Bovary?—and also between genres. In her best-selling work on home education, The Well-Trained Mind, the author provided a road map of classical education for parents wishing to home-school their children; that book is now the premier resource for home-schoolers. In The Well-Educated Mind, Bauer takes the same elements and techniques and adapts them to the use of adult readers who want both enjoyment and self-improvement from the time they spend reading. Followed carefully, her advice will restore and expand the pleasure of the written word. |

| alpha gel switch mechanical pencil: Net Smart Howard Rheingold, 2012-03-16 A media guru shows us how to use social media intelligently, humanely, and, above all, mindfully. Like it or not, knowing how to make use of online tools without being overloaded with too much information is an essential ingredient to personal success in the twenty-first century. But how can we use digital media so that they make us empowered participants rather than passive receivers, grounded, well-rounded people rather than multitasking basket cases? In Net Smart, cyberculture expert Howard Rheingold shows us how to use social media intelligently, humanely, and, above all, mindfully. Mindful use of digital media means thinking about what we are doing, cultivating an ongoing inner inquiry into how we want to spend our time. Rheingold outlines five fundamental digital literacies, online skills that will help us do this: attention, participation, collaboration, critical consumption of information (or crap detection), and network smarts. He explains how attention works, and how we can use our attention to focus on the tiny relevant portion of the incoming tsunami of information. He describes the quality of participation that empowers the best of the bloggers, netizens, tweeters, and other online community participants; he examines how successful online collaborative enterprises contribute new knowledge to the world in new ways; and he teaches us a lesson on networks and network building. Rheingold points out that there is a bigger social issue at work in digital literacy, one that goes beyond personal empowerment. If we combine our individual efforts wisely, it could produce a more thoughtful society: countless small acts like publishing a Web page or sharing a link could add up to a public good that enriches everybody. |

| alpha gel switch mechanical pencil: The Disappearing Spoon Sam Kean, 2010-07-12 From New York Times bestselling author Sam Kean comes incredible stories of science, history, finance, mythology, the arts, medicine, and more, as told by the Periodic Table. Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why is gallium (Ga, 31) the go-to element for laboratory pranksters? The Periodic Table is a crowning scientific achievement, but it's also a treasure trove of adventure, betrayal, and obsession. These fascinating tales follow every element on the table as they play out their parts in human history, and in the lives of the (frequently) mad scientists who discovered them. The Disappearing Spoon masterfully fuses science with the classic lore of invention, investigation, and discovery -- from the Big Bang through the end of time. Though solid at room temperature, gallium is a moldable metal that melts at 84 degrees Fahrenheit. A classic science prank is to mold gallium spoons, serve them with tea, and watch guests recoil as their utensils disappear. |

| alpha gel switch mechanical pencil: Engineering the Space Age - a Rocket Scientist Remembers Robert Brulle, 2012-08 Rarely is a reader exposed to such an extraordinary, multifaceted presentation of aerospace technology as Bob Brulle narrates in this book. After returning from duty as a combat fighter pilot in World War II, this Belgian immigrant developed a multitalented and innovative aerospace career path that addressed many of the aerospace professions. Along the way he forged a career in the aviation and space field that resulted in his participating in several of the most momentous aerospace achievements of the past century. He also expanded his education through hard work to a level at which he was qualified to teach graduate-level aerospace engineering courses. It is interesting to follow how the analysis and design techniques of aerospace vehicles progressed over the years, which incidentally reveals the large role that the computer played in making that possible. The story on the early Cape Canaveral operations was amusing and showed that enterprising innovations played a large role in a successful undertaking. Some of the projects described were a surprise, as I had never heard of them, like reading how a pencil-shaped missile was built that could fly and maneuver over an intercontinental distance at a high hypersonic velocity. He also described how American engineers and scientists fought the Cold War battle for technological supremacy on their desks and in their laboratories. The initiatives by which this enterprising engineer develops his technical approach to a project are very informative and offer the reader an insight into the workings of successful operations. He achieves an interesting behind-the-scenes look at how aerospace history is made by weaving in the historical significance of these projects as they are developed. As a former aeronautical engineer at the rapidly growing Mc- Donnell Aircraft Corporation, Bob gives us an interesting exposure to the importance of top management's relationship with the workforce in a successful company. Mr. Mac made it a point to make all his employees team members by frequent communication and friendly association. |
