Innumeracy in the Wild


Book Description

Innumeracy in the Wild presents the logic, rules, and habits that highly numerate people use in decision making, which the less numerate can employ to choose better. This text offers a state-of-the-art review of the now sizeable body of psychological and applied findings that demonstrate the critical importance of numeracy in our world. With more than two decades of experience in the decision sciences, Ellen Peters demonstrates how intervention can foster adult numeric capacity, propel people to use numeric facts in decision making, and empower people with lower numeracy to reason better.




No Stars to Wish on


Book Description

Each kid only has one pair of shoes here. Number 49's shoes are a pretty good fit for me and I know they're new because they still have that plastic smell. But the real Number 49 is quite a bit bigger than I am, because his pants keep falling down on me. I wish he would come back, so that I could go home. Jack loves telling jokes, but not many people laugh at them in the orphanage. Will he ever be reunited with his mother and sister, his great-aunts and great-grandmother, back at home? A haunting, fable-like story.




Millions, Billions, Zillions


Book Description

"Numbers are often intimidating, confusing, and even deliberately deceptive--especially when they are really big. The media loves to report on millions, billions, and trillions, but frequently makes basic mistakes or presents such numbers in misleading ways. And misunderstanding numbers can have serious consequences, since they can deceive us in many of our most important decisions, including how to vote, what to buy, and whether to make a financial investment. In this short, accessible, enlightening, and entertaining book, leading computer scientist Brian Kernighan teaches anyone--even diehard math-phobes--how to demystify the numbers that assault us every day. With examples drawn from a rich variety of sources, including journalism, advertising, and politics, Kernighan demonstrates how numbers can mislead and misrepresent. In chapters covering big numbers, units, dimensions, and more, he lays bare everything from deceptive graphs to speciously precise numbers. And he shows how anyone--using a few basic ideas and lots of shortcuts--can easily learn to recognize common mistakes, determine whether numbers are credible, and make their own sensible estimates when needed. Giving you the simple tools you need to avoid being fooled by dubious numbers, Millions, Billions, Zillions is an essential survival guide for a world drowning in big--and often bad--data"--Jacket




Priceless


Book Description

Prada stores carry a few obscenely expensive items in order to boost sales for everything else (which look like bargains in comparison). People used to download music for free, then Steve Jobs convinced them to pay. How? By charging 99 cents. That price has a hypnotic effect: the profit margin of the 99 Cents Only store is twice that of Wal-Mart. Why do text messages cost money, while e-mails are free? Why do jars of peanut butter keep getting smaller in order to keep the price the "same"? The answer is simple: prices are a collective hallucination. In Priceless, the bestselling author William Poundstone reveals the hidden psychology of value. In psychological experiments, people are unable to estimate "fair" prices accurately and are strongly influenced by the unconscious, irrational, and politically incorrect. It hasn't taken long for marketers to apply these findings. "Price consultants" advise retailers on how to convince consumers to pay more for less, and negotiation coaches offer similar advice for businesspeople cutting deals. The new psychology of price dictates the design of price tags, menus, rebates, "sale" ads, cell phone plans, supermarket aisles, real estate offers, wage packages, tort demands, and corporate buyouts. Prices are the most pervasive hidden persuaders of all. Rooted in the emerging field of behavioral decision theory, Priceless should prove indispensable to anyone who negotiates.




The Math of Life and Death


Book Description

"Few of us really appreciate the full power of math--the extent to which its influence is not only in every office and every home, but also in every courtroom and hospital ward. In this ... book, Kit Yates explores the true stories of life-changing events in which the application--or misapplication--of mathematics has played a critical role: patients crippled by faulty genes and entrepreneurs bankrupted by faulty algorithms; innocent victims of miscarriages of justice; and the unwitting victims of software glitches"--Publisher marketing.




Helping Children Learn Mathematics


Book Description

Results from national and international assessments indicate that school children in the United States are not learning mathematics well enough. Many students cannot correctly apply computational algorithms to solve problems. Their understanding and use of decimals and fractions are especially weak. Indeed, helping all children succeed in mathematics is an imperative national goal. However, for our youth to succeed, we need to change how we're teaching this discipline. Helping Children Learn Mathematics provides comprehensive and reliable information that will guide efforts to improve school mathematics from pre-kindergarten through eighth grade. The authors explain the five strands of mathematical proficiency and discuss the major changes that need to be made in mathematics instruction, instructional materials, assessments, teacher education, and the broader educational system and answers some of the frequently asked questions when it comes to mathematics instruction. The book concludes by providing recommended actions for parents and caregivers, teachers, administrators, and policy makers, stressing the importance that everyone work together to ensure a mathematically literate society.




Of Green Illusions


Book Description

The story of a young man that would help change the world in which he lived. He stood on the ledge of the great Cauldarian range looking down at his hand in which he held a rock. The beauty of it was overpowering, its green opaque luminescence made him feel falsely at ease. But he knew this was an object of beauty that no Cauldarian should posses. The stone represented the dark side of their history. The ideological faith and power that emanated from it could also be used for good. But its efficacy was wielded as if it were a sword striking at every aspect of the populaces' freedom. So far, its thrusts proved deadly in every instance. It had to be thrown over the ledge and into the night if his people were to survive. Michael awoke from this same dream that he had many times before. It was as if it were only yesterday that his world had changed; it was so different, but in many ways, it was still the same...




The Number Sense


Book Description

"Our understanding of how the human brain performs mathematical calculations is far from complete. In The Number Sense, Stanislas Dehaene offers readers an enlightening exploration of the mathematical mind. Using research showing that human infants have a rudimentary number sense, Dehaene suggests that this sense is as basic as our perception of color, and that it is wired into the brain. But how then did we leap from this basic number ability to trigonometry, calculus, and beyond? Dehaene shows that it was the invention of symbolic systems of numerals that started us on the climb to higher mathematics. Tracing the history of numbers, we learn that in early times, people indicated numbers by pointing to part of their bodies, and how Roman numerals were replaced by modern numbers. On the way, we also discover many fascinating facts: for example, because Chinese names for numbers are short, Chinese people can remember up to nine or ten digits at a time, while English-speaking people can only remember seven. A fascinating look at the crossroads where numbers and neurons intersect, The Number Sense offers an intriguing tour of how the structure of the brain shapes our mathematical abilities, and how math can open up a window on the human mind"--Provided by publisher.




Why We're Wrong About Nearly Everything


Book Description

A leading social researcher explains why humans so consistently misunderstand the outside world How often are women harassed? What percentage of the population are immigrants? How bad is unemployment? These questions are important, but most of us get the answers wrong. Research shows that people often wildly misunderstand the state of the world, regardless of age, sex, or education. And though the internet brings us unprecedented access to information, there's little evidence we're any better informed because of it. We may blame cognitive bias or fake news, but neither tells the complete story. In Why We're Wrong About Nearly Everything, Bobby Duffy draws on his research into public perception across more than forty countries, offering a sweeping account of the stubborn problem of human delusion: how society breeds it, why it will never go away, and what our misperceptions say about what we really believe. We won't always know the facts, but they still matter. Why We're Wrong About Nearly Everything is mandatory reading for anyone interested making humankind a little bit smarter.




The Volatility Machine


Book Description

This book presents a radically different argument for what has caused, and likely will continue to cause, the collapse of emerging market economies. Pettis combines the insights of economic history, economic theory, and finance theory into a comprehensive model for understanding sovereign liability management and the causes of financial crises. He examines recent financial crises in emerging market countries along with the history of international lending since the 1820s to argue that the process of international lending is driven primarily by external events and not by local politics and/or economic policies. He draws out the corporate finance implications of this approach to argue that most of the current analyses of the recent financial crises suffered by Latin America, Asia, and Russia have largely missed the point. He then develops a sovereign finance model, analogous to corporate finance, to understand the capital structure needs of emerging market countries. Using this model, he finally puts into perspective the recent crises, a new sovereign liability management theory, the implications of the model for sovereign debt restructurings, and the new financial architecture. Bridging the gap between finance specialists and traders, on the one hand, and economists and policy-makers on the other, The Volatility Machine is critical reading for anyone interested in where the international economy is going over the next several years.
