Proves that math can be serious fun!If you like any kind of game at all, you''ll enjoy the amazing mathematical brainteasers in this entertaining book. No special mathematics training is needed. With an emphasis on puzzling word problems with surprising solutions, the author presents his mathematical hurdles in order of increasing difficulty. Many appear deceptively simple, such as: How many quarter-inch marks are on an unusual sixteen-inch ruler? Or: If the cost of a bottle and a cork is $1.10 and the bottle costs $1.00 more than the cork, how much did the bottle alone cost? Check the answers before you decide that these are too easy. You may be surprised.Novices may want to begin with some of the teasers in the first "easy" section. More experienced math-heads may want to test their wits with the "challenging" or even the "difficult" sections (some are fiendishly difficult). Including word problems by famed mathematical puzzle geniuses Sam Loyd (1841 - 1911) and Henry Ernest Dudeney (1857 - 1930), which have entertained recreational math aficionados for more than a century, this book has something for puzzle solvers at any level. And for the math phobic, it may whet your appetite to delve into a subject you thought could only be boring.
This ain't your daddy's spy story. In a memoir written as a series of narrative vignettes, a former CIA operations officer recounts his years of danger, intrigue, and adventure.This candid and darkly witty memoir recounts an exhilarating life --and a few close brushes with death. With remarkable sangfroid and a humorist's eye for absurdity, H. K. Roy describes his many strange and risky exploits in his long career with the CIA. Whether he was pursuing Soviet and Cuban spies, running "denied area" operations in Eastern Europe, hunting Bosnian War criminals, or providing actionable intelligence to US government and coalition forces in Iraq, Roy usually found himself at the right place at the right time.Except when he didn't--like the time he stumbled into a life-threatening ambush by Iranian terrorists while dodging Serb snipers and shelling in Sarajevo. Eight summers later, caught in a blinding sandstorm between Amman and Baghdad, he learned his fate was in the hands of an Iraqi tribal chief who had just lost his entire family to a US airstrike in Ramadi, in a failed attempt to kill Saddam Hussein that had tragic consequences. Combining dedication to duty with a maverick's disdain for bureaucracy, Roy makes it clear that he prefers foreign locales to Washington and thrives on the adrenaline rush that comes with danger. He also sheds much light on why intelligence is an essential component of national defense, even our very survival as a nation.
A leading technology expert examines ways to manage the rapid proliferation of technology and come to grips with its pervasive influence.Technology--always a key driver of historical change--is transforming society as never before and at a far more rapid pace. This book takes the reader on a journey into what the author identifies as the central organizing construct for the future of civilization, the continued proliferation of technology. And he challenges us to consider how to think about technology to ensure that we humans, and not the products of our invention, remain in control of our destinies?In this informative and insightful examination, Dr. Daniel M. Gerstein--who brings vast operational, research, and academic experience to the subject--proposes a method for gaining a better understanding of how technology is likely to evolve in the future. He identifies the attributes that a future successful technology will seek to emulate and the pitfalls that a technology developer should try to avoid. The aim is to bring greater clarity to the impact of technology on individuals and society.In particular, he considers three technologies now converging that will shape the future: biotechnology, artificial intelligence, and the "internet of things." He asks: Will we continue to develop new technologies in these fields merely because basic research shows that we can, or should we first consider the likely effects of these technologies on the quality of life at the individual, societal, and global levels? Dr. Gerstein makes a compelling case that rational and informed evolution of our technological options is the best course for ensuring a brighter future.
Nobel laureate Steven Weinberg has written that "e;all that has happened since 1687 is a gloss on the Principia."e; Now you too can appreciate the significance of this stellar work, regarded by many as the greatest scientific contribution of all time. Despite its dazzling reputation, Isaac Newton's Philosophiae Naturalis Principia Mathematica, or simply the Principia, remains a mystery for many people. Few of even the most intellectually curious readers, including professional scientists and mathematicians, have actually looked in the Principia or appreciate its contents. Mathematician Pask seeks to remedy this deficit in this accessible guided tour through Newton's masterpiece. Using the final edition of the Principia, Pask clearly demonstrates how it sets out Newton's (and now our) approach to science; how the framework of classical mechanics is established; how terrestrial phenomena like the tides and projectile motion are explained; and how we can understand the dynamics of the solar system and the paths of comets. He also includes scene-setting chapters about Newton himself and scientific developments in his time, as well as chapters about the reception and influence of the Principia up to the present day.
A popular clinical psychologist explores an often misunderstood and unrecognized emotion that's the root cause of many self-defeating and harmful behaviors.Emotional paralysis, a distorted view of self, a feeling of being a fraud, lack of trust in others, fear of criticism resulting in underdeveloped talents, and a chronic sense of being worthless, invisible, or disposable--these are typical symptoms of shame. In this book, psychologist Stephan B. Poulter delves into this "primary emotional wound." Distinguishing it from commonplace guilt over a particular moral failing, he describes this toxic emotion as a pervasive but largely unrecognized "emotional cancer," with the power of undermining many aspects of life.Dr. Poulter guides the reader through exercises that teach one to expose this "big secret" and to recognize the triggers in daily life that arouse fears and other negative emotions. Beyond these first steps, he shows how we can continue the healing process of self-acceptance, self-forgiveness, empathy, and a new sense of inner well-being.Based on thirty years of experience with patients of all ages and from many walks of life, this is a book full of insight and understanding, one that can help most of us discover and realize our full potentials.
An expert on US election law presents an encouraging assessment of current efforts to make our voting system more accessible, reliable, and effective.In contrast to the anxiety surrounding our voting system, with stories about voter suppression and manipulation, there are actually quite a few positive initiatives toward voting rights reform. Professor Joshua A. Douglas, an expert on our electoral system, examines these encouraging developments in this inspiring book about how regular Americans are working to take back their democracy, one community at a time.Told through the narratives of those working on positive voting rights reforms, Douglas includes chapters on expanding voter eligibility, easing voter registration rules, making voting more convenient, enhancing accessibility at the polls, providing voters with more choices, finding ways to comply with voter ID rules, giving redistricting back to the voters, pushing back on big money through local and state efforts, using journalism to make the system more accountable, and improving civics education. At the end, the book includes an appendix that lists organizations all over the country working on these efforts.Unusually accessible for a lay audience and thoroughly researched, this book gives anyone fed up with our current political environment the ideas and tools necessary to affect change in their own communities.
This provocative and important overview of the challenges of and possible approaches to climate change by an expert and shared recipient of a Nobel Peace Prize is essential reading for policy makers, climate scientists, and lay persons alike.Though the Paris Agreement on climate change was a significant achievement, most authorities agree that its measures to reduce greenhouse-gas emissions will be insufficient to offset the forecasted increase in global warming. Even in the unlikely case of ideal compliance, the Earth will still experience major climate-driven damages. Given this reality, climate expert Roger A. Sedjo argues in this book that a Plan B is required. He makes a compelling case that doing more of the same, by focusing only on the mitigation plan of the Paris Agreement, will leave humanity increasingly vulnerable; instead, we must also begin planning adaptation strategies--Plan B--which enable societies to anticipate and protect against the worst effects of inevitable climate change. The author examines several areas where environmental damage could be severe. Sea-level rise is a major concern and measures could be, and in some cases are now being, undertaken to protect coastal areas. The author also addresses the need for more robust action to ward off the likely decline in agricultural productivity, destruction of forests and biodiversity, and the impact of natural catastrophes like hurricanes made worse by climate change. In addition, he considers geo-engineering strategies, such as atmospheric reflectivity, which may play a role in lessening the impact of global warming.
As one of the most gifted and prolific writers of the twentieth century, Isaac Asimov became legendary for his talent for explaining complex subjects in clear, concise prose. This book is a condensation of his three-volume autobiography, which spans Asimov's life.
Offers an exploration of how our understanding of evolution is key to the future of our planet. This title argues that understanding evolution has never mattered more in human history. It explains how health, food production, and human impact on the environment are dependent on our knowledge of evolution.
Was Jesus of Nazareth a real historical person or a fictional character in a religious legend? What do the Dead Sea Scrolls reveal about the origins of Christianity? Has there been a conspiracy to suppress information in the Scrolls that contradicts traditional church teaching? This book addresses these and many other questions.

A NASA insider tells the exciting story of robotic space missions to explore the solar system.Exploring the planets has been a goal of America's space program since the dawn of the space race. This insider's perspective examines incredible missions of robotic spacecraft to every corner of our solar system and beyond. Some were flown into glory, while others were planned and relegated to dusty filing cabinets. All were remarkable in their aspirations.Award-winning science writer Rod Pyle profiles both the remarkable spacecraft and the amazing scientists and engineers who made them possible. From the earliest sprints past Venus and Mars to Voyager1's current explorations of the space between the stars, this exciting book sheds new light on ever-more ambitious journeys designed to increase the human reach into the solar system. Drawing on his perspective as a writer for NASA's Jet Propulsion Laboratory, ground zero for NASA's planetary exploration, the author further details plans now in development to look for signs of life on Jupiter's moon Europa, submarines that will dive into the hazy hydrocarbon lakes of Saturn's moon Titan, and intelligent spacecraft that will operate for months without human intervention on Mars and in the outer solar system well into the 2030s. Equally compelling are programs of exploration that were considered but never left the drawing board, such as automobile-sized biology laboratories designed for a Mars landing in the 1960s and plans to detonate atomic bombs on the moon.Complemented by many rarely-seen photos and illustrations, these stories of incredible engineering achievements, daring imaginations, and technological genius will fascinate and inspire.
This primer on essential scientific literacy gives readers the basics to understand themselves and the world around them, plus a glimpse of how much more science has to offer.Science tells us a good deal about who we are, where we come from, the nature of the universe, how our brains work, and much, much more. Unfortunately, most people are largely unaware of this treasure trove of information. As a result, we are more prone to do things like aim nuclear weapons at each other, inflate the meaning of cultural differences, lay waste to the land, poison and deplete the oceans, fill the sky with carbon, and generally make poor judgments that cause needless trouble.This book seeks to remedy this situation by providing scientific answers to the most basic yet important questions about existence. Following the standard six-question list used by journalists researching a news story, critical-thinking advocate Guy P. Harrison turns to science to answer the who, what, why, when, where and how of life on Earth.How old is our planet? Where did it come from and where is it located in the universe? What is everything made of? When did life begin? Who are we as a species and what connections do we share with other life forms? Why is human culture continuously plagued by war, disease, and crime? Harrison not only offers science's best current answers to these crucial questions but shows how all of this information fits together. Going well beyond the simplistic factoids readily available on any smartphone, he reveals the wider implications and deeper meanings inherent in the scientific worldview.Both entertaining and informative, this exciting tour of the cosmos and human nature will leave readers with an accurate, up-to-date view of realities small and large, near and far.
