Book excerpt: “A captivating story, not just an intellectual quest but a personal one . . . gripping [and] filled with the passion and wonder of numbers.” —The New York Times Virtually everything in our lives is digital, numerical, or quantified. But the story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is the saga of Amir Aczel’s lifelong obsession: to find the original sources of our numerals, perhaps the greatest abstraction the human mind has ever created. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross-examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with Babylonian cuneiform numbers, followed by Greek and Roman letter numerals. Then Aczel asks: Where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero—the keystone of our entire system of numbers—on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves—who finally reveal where our numbers come from. “A historical adventure that doubles as a surprisingly engaging math lesson . . . rip-roaring exploits and escapades.” —Publishers Weekly

Download or read book We Have No Idea written by Jorge Cham and published by Penguin. This book was released on 2018-05-08 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepare to learn everything we still don’t know about our strange and mysterious universe Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore —there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the universe: the enormous holes in our knowledge of the cosmos. Armed with their popular infographics, cartoons, and unusually entertaining and lucid explanations of science, they give us the best answers currently available for a lot of questions that are still perplexing scientists, including: * Why does the universe have a speed limit? * Why aren't we all made of antimatter? * What (or who) is attacking Earth with tiny, superfast particles? * What is dark matter, and why does it keep ignoring us? It turns out the universe is full of weird things that don't make any sense. But Cham and Whiteson make a compelling case that the questions we can't answer are as interesting as the ones we can. This fully illustrated introduction to the biggest mysteries in physics also helpfully demystifies many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, Cham and Whiteson invite us to see the universe as a possibly boundless expanse of uncharted territory that's still ours to explore.

Download or read book Apocalypse Never written by Michael Shellenberger and published by HarperCollins. This book was released on 2020-06-30 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now a National Bestseller! Climate change is real but it’s not the end of the world. It is not even our most serious environmental problem. Michael Shellenberger has been fighting for a greener planet for decades. He helped save the world’s last unprotected redwoods. He co-created the predecessor to today’s Green New Deal. And he led a successful effort by climate scientists and activists to keep nuclear plants operating, preventing a spike of emissions. But in 2019, as some claimed “billions of people are going to die,” contributing to rising anxiety, including among adolescents, Shellenberger decided that, as a lifelong environmental activist, leading energy expert, and father of a teenage daughter, he needed to speak out to separate science from fiction. Despite decades of news media attention, many remain ignorant of basic facts. Carbon emissions peaked and have been declining in most developed nations for over a decade. Deaths from extreme weather, even in poor nations, declined 80 percent over the last four decades. And the risk of Earth warming to very high temperatures is increasingly unlikely thanks to slowing population growth and abundant natural gas. Curiously, the people who are the most alarmist about the problems also tend to oppose the obvious solutions. What’s really behind the rise of apocalyptic environmentalism? There are powerful financial interests. There are desires for status and power. But most of all there is a desire among supposedly secular people for transcendence. This spiritual impulse can be natural and healthy. But in preaching fear without love, and guilt without redemption, the new religion is failing to satisfy our deepest psychological and existential needs.

Download or read book The Poison Squad written by Deborah Blum and published by Penguin. This book was released on 2018-09-25 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New York Times Notable Book The inspiration for PBS's AMERICAN EXPERIENCE film The Poison Squad. From Pulitzer Prize winner and New York Times-bestselling author Deborah Blum, the dramatic true story of how food was made safe in the United States and the heroes, led by the inimitable Dr. Harvey Washington Wiley, who fought for change By the end of nineteenth century, food was dangerous. Lethal, even. "Milk" might contain formaldehyde, most often used to embalm corpses. Decaying meat was preserved with both salicylic acid, a pharmaceutical chemical, and borax, a compound first identified as a cleaning product. This was not by accident; food manufacturers had rushed to embrace the rise of industrial chemistry, and were knowingly selling harmful products. Unchecked by government regulation, basic safety, or even labelling requirements, they put profit before the health of their customers. By some estimates, in New York City alone, thousands of children were killed by "embalmed milk" every year. Citizens--activists, journalists, scientists, and women's groups--began agitating for change. But even as protective measures were enacted in Europe, American corporations blocked even modest regulations. Then, in 1883, Dr. Harvey Washington Wiley, a chemistry professor from Purdue University, was named chief chemist of the agriculture department, and the agency began methodically investigating food and drink fraud, even conducting shocking human tests on groups of young men who came to be known as, "The Poison Squad." Over the next thirty years, a titanic struggle took place, with the courageous and fascinating Dr. Wiley campaigning indefatigably for food safety and consumer protection. Together with a gallant cast, including the muckraking reporter Upton Sinclair, whose fiction revealed the horrific truth about the Chicago stockyards; Fannie Farmer, then the most famous cookbook author in the country; and Henry J. Heinz, one of the few food producers who actively advocated for pure food, Dr. Wiley changed history. When the landmark 1906 Food and Drug Act was finally passed, it was known across the land, as "Dr. Wiley's Law." Blum brings to life this timeless and hugely satisfying "David and Goliath" tale with righteous verve and style, driving home the moral imperative of confronting corporate greed and government corruption with a bracing clarity, which speaks resoundingly to the enormous social and political challenges we face today.
Download or read book Science on a Mission written by Naomi Oreskes and published by University of Chicago Press. This book was released on 2021-04-19 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vivid portrait of how Naval oversight shaped American oceanography, revealing what difference it makes who pays for science. What difference does it make who pays for science? Some might say none. If scientists seek to discover fundamental truths about the world, and they do so in an objective manner using well-established methods, then how could it matter who’s footing the bill? History, however, suggests otherwise. In science, as elsewhere, money is power. Tracing the recent history of oceanography, Naomi Oreskes discloses dramatic changes in American ocean science since the Cold War, uncovering how and why it changed. Much of it has to do with who pays. After World War II, the US military turned to a new, uncharted theater of warfare: the deep sea. The earth sciences—particularly physical oceanography and marine geophysics—became essential to the US Navy, which poured unprecedented money and logistical support into their study. Science on a Mission brings to light how this influx of military funding was both enabling and constricting: it resulted in the creation of important domains of knowledge but also significant, lasting, and consequential domains of ignorance. As Oreskes delves into the role of patronage in the history of science, what emerges is a vivid portrait of how naval oversight transformed what we know about the sea. It is a detailed, sweeping history that illuminates the ways funding shapes the subject, scope, and tenor of scientific work, and it raises profound questions about the purpose and character of American science. What difference does it make who pays? The short answer is: a lot.
Download or read book Expert Political Judgment written by Philip E. Tetlock and published by Princeton University Press. This book was released on 2017-08-29 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its original publication, Expert Political Judgment by New York Times bestselling author Philip Tetlock has established itself as a contemporary classic in the literature on evaluating expert opinion. Tetlock first discusses arguments about whether the world is too complex for people to find the tools to understand political phenomena, let alone predict the future. He evaluates predictions from experts in different fields, comparing them to predictions by well-informed laity or those based on simple extrapolation from current trends. He goes on to analyze which styles of thinking are more successful in forecasting. Classifying thinking styles using Isaiah Berlin's prototypes of the fox and the hedgehog, Tetlock contends that the fox--the thinker who knows many little things, draws from an eclectic array of traditions, and is better able to improvise in response to changing events--is more successful in predicting the future than the hedgehog, who knows one big thing, toils devotedly within one tradition, and imposes formulaic solutions on ill-defined problems. He notes a perversely inverse relationship between the best scientific indicators of good judgement and the qualities that the media most prizes in pundits--the single-minded determination required to prevail in ideological combat. Clearly written and impeccably researched, the book fills a huge void in the literature on evaluating expert opinion. It will appeal across many academic disciplines as well as to corporations seeking to develop standards for judging expert decision-making. Now with a new preface in which Tetlock discusses the latest research in the field, the book explores what constitutes good judgment in predicting future events and looks at why experts are often wrong in their forecasts.
Download or read book Open Questions in Quantum Physics written by G. Tarozzi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its extraordinary predictive power and the great generality of its mathematical structure, quantum theory is able, at least in principle, to describe all the microscopic and macroscopic properties of the physical world, from the subatomic to the cosmological level. Nevertheless, ever since the Copen hagen and Gottingen schools in 1927 gave it the definitive formu lation, now commonly known as the orthodox interpretation, the theory has suffered from very serious logical and epistemologi cal problems. These shortcomings were immediately pointed out by some of the principal founders themselves of quantum theory, to wit, Planck, Einstein, Ehrenfest, Schrodinger, and de Broglie, and by the philosopher Karl Popper, who assumed a position of radical criticism with regard to the standard formulation of the theory. The aim of the participants in the workshop on Open Questions in Quantum Physics, which was held in Bari (Italy), in the Department of Physics of the University, during May 1983 and whose Proceedings are collected in the present volume, accord ingly was to discuss the formal, the physical and the epistemo logical difficulties of quantum theory in the light of recent crucial developments and to propose some possible resolutions of three basic conceptual dilemmas, which are posed respectively ~: (a) the physical developments of the Einstein-Podolsky-Rosen argument and Bell's theorem, i. e.

Download or read book The Submerged State written by Suzanne Mettler and published by University of Chicago Press. This book was released on 2011-08-31 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Keep your government hands off my Medicare!” Such comments spotlight a central question animating Suzanne Mettler’s provocative and timely book: why are many Americans unaware of government social benefits and so hostile to them in principle, even though they receive them? The Obama administration has been roundly criticized for its inability to convey how much it has accomplished for ordinary citizens. Mettler argues that this difficulty is not merely a failure of communication; rather it is endemic to the formidable presence of the “submerged state.” In recent decades, federal policymakers have increasingly shunned the outright disbursing of benefits to individuals and families and favored instead less visible and more indirect incentives and subsidies, from tax breaks to payments for services to private companies. These submerged policies, Mettler shows, obscure the role of government and exaggerate that of the market. As a result, citizens are unaware not only of the benefits they receive, but of the massive advantages given to powerful interests, such as insurance companies and the financial industry. Neither do they realize that the policies of the submerged state shower their largest benefits on the most affluent Americans, exacerbating inequality. Mettler analyzes three Obama reforms—student aid, tax relief, and health care—to reveal the submerged state and its consequences, demonstrating how structurally difficult it is to enact policy reforms and even to obtain public recognition for achieving them. She concludes with recommendations for reform to help make hidden policies more visible and governance more comprehensible to all Americans. The sad truth is that many American citizens do not know how major social programs work—or even whether they benefit from them. Suzanne Mettler’s important new book will bring government policies back to the surface and encourage citizens to reclaim their voice in the political process.

Download or read book The End Of Science written by John Horgan and published by Basic Books. This book was released on 2015-04-14 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: As staff writer for Scientific American, John Horgan has a window on contemporary science unsurpassed in all the world. Who else routinely interviews the likes of Lynn Margulis, Roger Penrose, Francis Crick, Richard Dawkins, Freeman Dyson, Murray Gell-Mann, Stephen Jay Gould, Stephen Hawking, Thomas Kuhn, Chris Langton, Karl Popper, Stephen Weinberg, and E.O. Wilson, with the freedom to probe their innermost thoughts? In The End Of Science, Horgan displays his genius for getting these larger-than-life figures to be simply human, and scientists, he writes, "are rarely so human . . . so at there mercy of their fears and desires, as when they are confronting the limits of knowledge."This is the secret fear that Horgan pursues throughout this remarkable book: Have the big questions all been answered? Has all the knowledge worth pursuing become known? Will there be a final "theory of everything" that signals the end? Is the age of great discoverers behind us? Is science today reduced to mere puzzle solving and adding detains to existing theories? Horgan extracts surprisingly candid answers to there and other delicate questions as he discusses God, Star Trek, superstrings, quarks, plectics, consciousness, Neural Darwinism, Marx's view of progress, Kuhn's view of revolutions, cellular automata, robots, and the Omega Point, with Fred Hoyle, Noam Chomsky, John Wheeler, Clifford Geertz, and dozens of other eminent scholars. The resulting narrative will both infuriate and delight as it mindless Horgan's smart, contrarian argument for "endism" with a witty, thoughtful, even profound overview of the entire scientific enterprise. Scientists have always set themselves apart from other scholars in the belief that they do not construct the truth, they discover it. Their work is not interpretation but simple revelation of what exists in the empirical universe. But science itself keeps imposing limits on its own power. Special relativity prohibits the transmission of matter or information as speeds faster than that of light; quantum mechanics dictates uncertainty; and chaos theory confirms the impossibility of complete prediction. Meanwhile, the very idea of scientific rationality is under fire from Neo-Luddites, animal-rights activists, religious fundamentalists, and New Agers alike. As Horgan makes clear, perhaps the greatest threat to science may come from losing its special place in the hierarchy of disciplines, being reduced to something more akin to literaty criticism as more and more theoreticians engage in the theory twiddling he calls "ironic science." Still, while Horgan offers his critique, grounded in the thinking of the world's leading researchers, he offers homage too. If science is ending, he maintains, it is only because it has done its work so well.
Download or read book Discerning Experts written by Michael Oppenheimer and published by University of Chicago Press. This book was released on 2019-03-07 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discerning Experts assesses the assessments that many governments rely on to help guide environmental policy and action. Through their close look at environmental assessments involving acid rain, ozone depletion, and sea level rise, the authors explore how experts deliberate and decide on the scientific facts about problems like climate change. They also seek to understand how the scientists involved make the judgments they do, how the organization and management of assessment activities affects those judgments, and how expertise is identified and constructed. Discerning Experts uncovers factors that can generate systematic bias and error, and recommends how the process can be improved. As the first study of the internal workings of large environmental assessments, this book reveals their strengths and weaknesses, and explains what assessments can—and cannot—be expected to contribute to public policy and the common good.
