do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

    A fun and fascinating look at great scientific paradoxes.   Throughout history, scientists have come up with theories and ideas that just don't seem to make sense.  These we call paradoxes.  The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds.  For example, how can a cat be both dead and alive at the same time?  Why will Achilles never beat a tortoise in a race, no matter how fast he runs?  And how can a person be ten years older than his twin?   With elegant explanations that bring the reader inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.  Just as surely as Al-Khalili narrates the enduring fascination of these classic paradoxes, he reveals their underlying logic.  In doing so, he brings to life a select group of the most exciting concepts in human knowledge.  Paradox is mind-expanding fun.

    C. J. Peters was on the front lines of our biological battle against “hot” viruses around the world. In the course of that career, he learned countless lessons about our interspecies turf wars with infectious agents. Called in to contain an outbreak of deadly hemorrhagic fever in Bolivia, he confronted the despair of trying to save a colleague who accidentally infected himself with an errant scalpel. Working in Level 4 labs on the Machupo and Ebola viruses, he saw time and again why expensive high-tech biohazard containment equipment is only as safe as the people who use it.   Because of new, emerging viruses, and the return of old, “vanquished” ones for which vaccines do not exist, there remains a very real danger of a new epidemic that could, without proper surveillance and early intervention, spread worldwide virtually overnight. And the possibility of foreign countries or terrorist groups using deadly airborne viruses—the poor man’s nuclear arsenal—looms larger than ever.   High-octane science writing at its best and most revealing, Virus Hunter is a thrilling first-person account of what it is like to be a warrior in the Hot Zone.

    Since 9/11, more than four million illegal immigrants have crossed our borders, and there are more coming every day. Our leaders in Washington lack the political will to uphold the rule of law. The Melting Pot is broken beyond repair, and the future of our nation is at stake.In this important book, Pat Buchanan reveals that, slowly but surely, the great American Southwest is being reconquered by Mexico. These lands---which many Mexicans believe are their birthright---are being detached ethnically, linguistically, and culturally from the United States by a deliberate policy of the Mexican regime. This is the "Aztlan Plot" for "La Reconquista," the recapture of the lands lost by Mexico in the Texas War of Independence and Mexican-American War. Comparing the immigrant invasion of America from across the Mexican border---and of Europe from across the Mediterranean---to the barbarian invasions that ended the Roman Empire, the author writes with passion and conviction that we have begun the final chapter of the Death of the West. Unless the invasion is halted now, Buchanan argues, by midcentury America will be a country unrecognizable to our parents, the Third World dystopia that Theodore Roosevelt warned against when he said we must never let America become a "polyglot boardinghouse" for the world. President Bush's failure to halt the invasion and secure America's border, Buchanan writes, is a dereliction of constitutional duty that, in other times, would have called forth articles of impeachment. In the final chapter, "Last Chance," he lays out a sweeping immigration reform and border security plan, which, he contends, if not pursued, means George W. Bush's legacy will be to have lost for America a Southwest that was the legacy of Sam Houston, Andrew Jackson, and James K. Polk. With an estimated ten to fifteen million "illegals" already here and tens of millions more poised to pour across our borders, few books could be as timely---or important---as "State of Emergency." It is essential reading for all Americans.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    Incorporating biological, medicinal, and environmental applications, it builts an art program. Highlighting the art program are micro-to-macro art pieces that visually guide students to conceptually understand organic chemistry.

    He sifts through over 30,000 survey submissions to uncover the world’s favourite number, and meets a mathematician who looks for universes in his garage. He attends the World Mathematical Congress in India, and visits the engineer who designed the first roller-coaster loop. Get hooked on math as Alex delves deep into humankind’s turbulent relationship with numbers, and reveals how they have shaped the world we live in.

    Unless the train is stopped, it will inevitably kill all five men. You are standing on a footbridge looking down on the unfolding disaster. However, a fat man, a stranger, is standing next to you: if you push him off the bridge, he will topple onto the line and, although he will die, his chunky body will stop the train, saving five lives. Would you kill the fat man?The question may seem bizarre. But it's one variation of a puzzle that has baffled moral philosophers for almost half a century and that more recently has come to preoccupy neuroscientists, psychologists, and other thinkers as well. In this book, David Edmonds, coauthor of the bestselling Wittgenstein's Poker, tells the riveting story of why and how philosophers have struggled with this ethical dilemma, sometimes called the trolley problem. In the process, he provides an entertaining and informative tour through the history of moral philosophy. Most people feel it's wrong to kill the fat man. But why? After all, in taking one life you could save five. As Edmonds shows, answering the question is far more complex--and important--than it first appears. In fact, how we answer it tells us a great deal about right and wrong.

    Gross national product, balance of trade, unemployment, inflation, and consumer confidence guide our actions, yet few of us know where these numbers come from, what they mean, or why they rule our world.In The Leading Indicators, Zachary Karabell tells the fascinating history of these indicators. They were invented in the mid-twentieth century to address the urgent challenges of the Great Depression, World War II, and the Cold War. They were rough measures— designed to give clarity in a data-parched world that was made up of centralized, industrial nations—yet we still rely on them today.We live in a world shaped by information technology and the borderless flow of capital and goods. When we follow a 1950s road map for a twenty-first-century world, we shouldn’t be surprised if we get lost.What is urgently needed, Karabell makes clear, is not that we invent a new set of numbers but that we tap into the thriving data revolution, which offers unparalleled access to the information we need. Companies should not base their business plans on GDP projections; individuals should not decide whether to buy a home or get a degree based on the national unemployment rate. If you want to buy a home, look for a job, start a company, or run a business, you should find your own indicators. National housing figures don’t matter; local ones do. You can find them at the click of a button. Personal, made-to-order indicators will meet our needs today, and the revolution is well underway. We need only to join it.

    . . . One rejoices in Bronowski’s dedication to the identity of acts of creativity and of imagination, whether in Blake or Yeats or Einstein or Heisenberg.”—Kirkus Reviews “A delightful look at the inquiring mind.”—Library JournalIn this eloquent volume Jacob Bronowski, mathematician and scientist, presents a succinct introduction to the state of modern thinking about the role of science in man's intellectual and moral life. Weaving together themes from ethnology, linguistics, philosophy, and physics, he confronts the questions of who we are, what we are, and how we relate to the universe around us.

    Their results shocked the world and created stirring conversation about global 'overshoot,' or resource use beyond the carrying capacity of the planet. Now, preeminent environmental scientists Donnella Meadows, Jorgen Randers, and Dennis Meadows have teamed up again to update and expand their original findings in The Limits to Growth: The 30 Year Global Update.Meadows, Randers, and Meadows are international environmental leaders recognized for their groundbreaking research into early signs of wear on the planet. Citing climate change as the most tangible example of our current overshoot, the scientists now provide us with an updated scenario and a plan to reduce our needs to meet the carrying capacity of the planet.Over the past three decades, population growth and global warming have forged on with a striking semblance to the scenarios laid out by the World3 computer model in the original Limits to Growth. While Meadows, Randers, and Meadows do not make a practice of predicting future environmental degradation, they offer an analysis of present and future trends in resource use, and assess a variety of possible outcomes.In many ways, the message contained in Limits to Growth: The 30-Year Update is a warning. Overshoot cannot be sustained without collapse. But, as the authors are careful to point out, there is reason to believe that humanity can still reverse some of its damage to Earth if it takes appropriate measures to reduce inefficiency and waste.Written in refreshingly accessible prose, Limits to Growth: The 30-Year Update is a long anticipated revival of some of the original voices in the growing chorus of sustainability. Limits to Growth: The 30 Year Update is a work of stunning intelligence that will expose for humanity the hazy but critical line between human growth and human development.

    At the dawn of the Industrial Revolution in eighteenth-century England, standards of measurement were established, giving way to the development of machine tools—machines that make machines. Eventually, the application of precision tools and methods resulted in the creation and mass production of items from guns and glass to mirrors, lenses, and cameras—and eventually gave way to further breakthroughs, including gene splicing, microchips, and the Hadron Collider.Simon Winchester takes us back to origins of the Industrial Age, to England where he introduces the scientific minds that helped usher in modern production: John Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. It was Thomas Jefferson who later exported their discoveries to the fledgling United States, setting the nation on its course to become a manufacturing titan. Winchester moves forward through time, to today’s cutting-edge developments occurring around the world, from America to Western Europe to Asia.As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?

    Mankind is reengineering the planet, investing up to ten trillion dollars per year in transportation, energy, and communications infrastructure linking the world’s burgeoning megacities together. This has profound consequences for geopolitics, economics, demographics, the environment, and social identity. Connectivity, not geography, is our destiny. In Connectography, visionary strategist Parag Khanna travels from Ukraine to Iran, Mongolia to North Korea, Pakistan to Nigeria, and across the Arctic Circle and the South China Sea to explain the rapid and unprecedented changes affecting every part of the planet. He shows how militaries are deployed to protect supply chains as much as borders, and how nations are less at war over territory than engaged in tugs-of-war over pipelines, railways, shipping lanes, and Internet cables. The new arms race is to connect to the most markets—a race China is now winning, having launched a wave of infrastructure investments to unite Eurasia around its new Silk Roads. The United States can only regain ground by fusing with its neighbors into a super-continental North American Union of shared resources and prosperity.Connectography offers a unique and hopeful vision for the future. Khanna argues that new energy discoveries and technologies have eliminated the need for resource wars; ambitious transport corridors and power grids are unscrambling Africa’s fraught colonial borders; even the Arab world is evolving a more peaceful map as it builds resource and trade routes across its war-torn landscape. At the same time, thriving hubs such as Singapore and Dubai are injecting dynamism into young and heavily populated regions, cyber-communities empower commerce across vast distances, and the world’s ballooning financial assets are being wisely invested into building an inclusive global society. Beneath the chaos of a world that appears to be falling apart is a new foundation of connectivity pulling it together.Advance praise for Connectography“Connectography is ahead of the curve in seeing the battlefield of the future and the new kind of tug-of-war being waged on it. Khanna’s scholarship and foresight are world-class. . . . A must-read for the next president.”—Chuck Hagel, former U.S. secretary of defense “This bold reframing is an exciting addition to our ongoing debate about geopolitics and the future of globalization.”—Dominic Barton, global managing partner, McKinsey & Company “This is probably the most global book ever written. It is intensely specific while remaining broad and wide. Its takeaway is that infrastructure is destiny: Follow the supply lines outlined in this book to see where the future flows.”—Kevin Kelly, co-founder, Wired “There’s no better guide than Khanna to show us all the possibilities of this new hyperconnected world.”—Mathew Burrows, director, Strategic Foresight Initiative at the Atlantic Council, and former counselor, U.S. National Intelligence Council “This book is an invaluable resource for anyone involved in business, science, arts, or any other field.”—Mark Mobius, executive chairman, Templeton Emerging Markets Group “A must-read for anyone who wants to understand the future of humanity.”—Sandy Pentland, professor, MIT Media Lab
