This recreational math book takes the reader on a fantastic voyage into the world of natural numbers. From the earliest discoveries of the ancient Greeks to various fundamental characteristics of the natural number sequence, Clawson explains fascinating mathematical mysteries in clear and easy prose. He delves into the heart of number theory to see and understand the exquisite relationships among natural numbers, and ends by exploring the ultimate mystery of mathematics: the Riemann hypothesis, which says that through a point in a plane, no line can be drawn parallel to a given line.While a professional mathematician's treatment of number theory involves the most sophisticated analytical tools, its basic ideas are surprisingly easy to comprehend. By concentrating on the meaning behind various equations and proofs and avoiding technical refinements, Mathematical Mysteries lets the common reader catch a glimpse of this wonderful and exotic world.

    I’m Tim. I’m a single cell in society’s body. U.S. society, to be specific.So let me explain why we’re here.As a writer and a generally thinky person, I’ve spent a lot of my life thinking about the society I live in, and societies in general. I’ve always imagined society as a kind of giant human—a living organism like each of us, only much bigger.When you’re a single cell in the body of a giant, it’s hard to understand what the giant’s doing, or why it is the way it is, because you can’t really zoom out and look at the whole thing all at once. But we do our best.The thing is, when I’ve recently tried to imagine what society might look like, I haven’t really been picturing this:Giant stick figure: "I am grown up."Based on what I see around me, in person and online, it seems like my society is actually more like this:Giant stick figure throwing a giant tantrum because their chocolate ice cream fell on the ground.Individual humans grow older as they age—but it kind of seems like the giant human I live in has been getting more childish each year that goes by.So I decided to write a blog post about this. But then something else happened.When I told people I was planning to write a post about society, and the way people are acting, and the way the media is acting, and the way the government is acting, and the way everyone else is acting, people kept saying the same thing to me.Don’t do it. Don’t touch it. Write about something else. Anything else. It’s just not worth it.They were right. With so many non-controversial topics to write about, why take on something so loaded and risk alienating a ton of readers? I listened to people’s warnings, and I thought about moving on to something else, but then I was like, “Wait what? I live inside a giant and the giant is having a six-year-old meltdown in the grocery store candy section and that’s a not-okay thing for me to talk about?”It hit me that what I really needed to write about was that—about why it’s perilous to write about society."

    It was a sea in name only. It was actually a bone dry, ancient dusty basin pockmarked with craters and littered with rocks and boulders. Somewhere in that 500 mile diameter basin, the astronauts would attempt to make Mankind’s first landing on the Moon. Neil Armstrong would pilot the Lunar Module “Eagle” during its twelve minute descent from orbit down to a landing. Col. Edwin “Buzz” Aldrin would assist him. On the way down they would encounter a host of problems, any one of which could have potentially caused them to have to call off the landing, or, even worse, die making the attempt. The problems were all technical-communications problems, computer problems, guidance problems, sensor problems. Armstrong and Aldrin faced the very real risk of dying by the very same technical sword that they had to live by in order to accomplish the enormous task of landing on the Moon for the first time. Yet the human skills Armstrong and Aldrin employed would be more than equal to the task. Armstrong’s formidable skills as an aviator, honed from the time he was a young boy, would serve him well as he piloted Eagle down amidst a continuing series of systems problems that might have fatally distracted a lesser aviator. Armstrong’s brilliant piloting was complemented by Aldrin’s equally remarkable discipline and calmness as he stoically provided a running commentary on altitude and descent rate while handling systems problems that threatened the landing. Finally, after a harrowing twelve and a half minutes, Armstrong gently landed Eagle at “Tranquility Base”, a name he had personally chosen to denote the location of the first Moon landing. In “Landing Eagle-Inside the Cockpit During the First Moon Landing”, author Mike Engle gives a minute by minute account of the events that occurred throughout Eagle’s descent and landing on the Moon. Engle, a retired NASA engineer and Mission Control flight controller, uses NASA audio files of actual voice recordings made inside Eagle’s cockpit during landing to give the reader an “inside the cockpit” perspective on the first Moon landing. Engle’s transcripts of these recordings, along with background material on the history and technical details behind the enormous effort to accomplish the first Moon landing, give a new and fascinating insight into the events that occurred on that remarkable day fifty years ago.

    The author looks at changing attitudes to pleasure over the centuries, including religious and philosophical lawgiving on the subject, before moving on to the science of all this human frenzy.

    Mountains of print have been written about culture. Loonshots identifies the small shifts in structure that control this transition, the same way that temperature controls the change from water to ice.Using examples that range from the spread of fires in forests to the hunt for terrorists online, and stories of thieves and geniuses and kings, Bahcall shows how this new kind of science helps us understand the behavior of companies and the fate of empires. Loonshots distills these insights into lessons for creatives, entrepreneurs, and visionaries everywhere.

    It was a time of economic miracles, an era when steady jobs were easy to find and families could see their living standards improving year after year. And then, around 1973, the good times vanished. The world economy slumped badly, then settled into the slow, erratic growth that had been the norm before the war. The result was an era of anxiety, uncertainty, and political extremism that we are still grappling with today. In An Extraordinary Time, acclaimed economic historian Marc Levinson describes how the end of the postwar boom reverberated throughout the global economy, bringing energy shortages, financial crises, soaring unemployment, and a gnawing sense of insecurity. Politicians, suddenly unable to deliver the prosperity of years past, railed haplessly against currency speculators, oil sheikhs, and other forces they could not control. From Sweden to Southern California, citizens grew suspicious of their newly ineffective governments and rebelled against the high taxes needed to support social welfare programs enacted when coffers were flush. Almost everywhere, the pendulum swung to the right, bringing politicians like Margaret Thatcher and Ronald Reagan to power. But their promise that deregulation, privatization, lower tax rates, and smaller government would restore economic security and robust growth proved unfounded. Although the guiding hand of the state could no longer deliver the steady economic performance the public had come to expect, free-market policies were equally unable to do so. The golden age would not come back again. A sweeping reappraisal of the last sixty years of world history, An Extraordinary Time forces us to come to terms with how little control we actually have over the economy.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    In 1985 Hans von Ohain, the scientist who pioneered Nazi Germany's efforts to build a jet plane, posed the question: 'Would World War II have occured if the Luftwaffe knew it faced operational British jets instead of Spitfires?' He immediately answered, 'I, for one, think not.'Frank Whittle, working-class outsider and self-taught enthusiast, had worked out the blueprint of a completely new type of engine in 1929, only for his ideas to be blocked by bureaucratic opposition until the outbreak of war in 1939. The importance of his work was recognized too late by the government for his revolutionary engine to play a major part in World War II. After the war Whittle's dream of civilian jet-powered aircraft became a reality and Britain enjoyed a golden age of 1950's jet-powered flight.Drawing on Whittle's extensive private papers, Campbell-Smith tells the story of a stoic and overlooked British hero, a tantalizing tale of 'what might have been'.

    Campbell presents the epic tales of Texas history in a new light, offering revisionist history in the best sense--broadening and deepening the traditional story, without ignoring the heroes of the past. The scope of the book is impressive. It ranges from the archeological record of early Native Americans to the rise of the oil industry and ultimately the modernization of Texas. Campbell provides swift-moving accounts of the Mexican revolution against Spain, the arrival of settlers from the United States, and the lasting Spanish legacy (from place names to cattle ranching to civil law). The author also paints a rich portrait of the Anglo-Texan revolution, with its larger-than-life leaders and epic battles, the fascinating decade of the Republic of Texas, and annexation by the United States. In his account of the Civil War and Reconstruction, he examines developments both in local politics and society and in the nation at large (from the debate over secession to the role of Texas troops in the Confederate army to the impact of postwar civil rights laws). Late nineteenth-century Texas is presented as part of both the Old West and the New South. The story continues with an analysis of the impact of the Populist and Progressive movements and then looks at the prosperity decade of the 1920s and the economic disaster of the Great Depression. Campbell's last chapters show how World War II brought economic recovery and touched off spectacular growth that, with only a few downturns, continues until today. Lucid, engaging, deftly written, Gone to Texas offers a fresh understanding of why Texas continues to be seen as a state unlike any other, a place that distills the essence of what it means to be an American.

    Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge--from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool--the general principle--from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.Street-Fighting Mathematics will appear in print and online under a Creative Commons Noncommercial Share Alike license.

     Celebrated writer and contrarian Bill James has voraciously read true crime throughout his life and has been interested in writing a book on the topic for decades. Now, with Popular Crime, James takes readers on an epic journey from Lizzie Borden to the Lindbergh baby, from the Black Dahlia to O. J. Simpson, explaining how crimes have been committed, investigated, prosecuted and written about, and how that has profoundly influenced our culture over the last few centuries— even if we haven’t always taken notice. Exploring such phenomena as serial murder, the fluctuation of crime rates, the value of evidence, radicalism and crime, prison reform and the hidden ways in which crimes have shaped, or reflected, our society, James chronicles murder and misdeeds from the 1600s to the present day. James pays particular attention to crimes that were sensations during their time but have faded into obscurity, as well as still-famous cases, some that have never been solved, including the Lindbergh kidnapping, the Boston Strangler and JonBenet Ramsey. Satisfyingly sprawling and tremendously entertaining, Popular Crime is a professed amateur’s powerful examination of the incredible impact crime stories have on our society, culture and history.
