Based on the abstract, general style of mathematical exposition favored by research mathematicians, its goal was to teach students not just to manipulate numbers and formulas, but to grasp the underlying mathematical concepts. The result, at least at first, was a great deal of confusion among teachers, students, and parents. Since then, the negative aspects of "new math" have been eliminated and its positive elements assimilated into classroom instruction.In this charming volume, a noted English mathematician uses humor and anecdote to illuminate the concepts underlying "new math": groups, sets, subsets, topology, Boolean algebra, and more. According to Professor Stewart, an understanding of these concepts offers the best route to grasping the true nature of mathematics, in particular the power, beauty, and utility of pure mathematics. No advanced mathematical background is needed (a smattering of algebra, geometry, and trigonometry is helpful) to follow the author's lucid and thought-provoking discussions of such topics as functions, symmetry, axiomatics, counting, topology, hyperspace, linear algebra, real analysis, probability, computers, applications of modern mathematics, and much more.By the time readers have finished this book, they'll have a much clearer grasp of how modern mathematicians look at figures, functions, and formulas and how a firm grasp of the ideas underlying "new math" leads toward a genuine comprehension of the nature of mathematics itself.

    But in our zeal to instill the evaluation process with scientific rigor, we've gone from measuring performance to fixating on measuring itself. The result is a tyranny of metrics that threatens the quality of our lives and most important institutions. In this timely and powerful book, Jerry Muller uncovers the damage our obsession with metrics is causing--and shows how we can begin to fix the problem.Filled with examples from education, medicine, business and finance, government, the police and military, and philanthropy and foreign aid, this brief and accessible book explains why the seemingly irresistible pressure to quantify performance distorts and distracts, whether by encouraging "gaming the stats" or "teaching to the test." That's because what can and does get measured is not always worth measuring, may not be what we really want to know, and may draw effort away from the things we care about. Along the way, we learn why paying for measured performance doesn't work, why surgical scorecards may increase deaths, and much more. But metrics can be good when used as a complement to--rather than a replacement for--judgment based on personal experience, and Muller also gives examples of when metrics have been beneficial.Complete with a checklist of when and how to use metrics, The Tyranny of Metrics is an essential corrective to a rarely questioned trend that increasingly affects us all.

    With a few words, the Fed can lift the stock market out of desperation and catapult it towards euphoric highs. With a few keystrokes, the Fed can conjure up trillions of dollars and fund virtually unlimited Federal spending. And with a few poor decisions, the Fed can plunge the entire world into a recession. The Federal Reserve is one of the most powerful institutions in the world, and also one of the most difficult to understand.The Fed acts through its Open Markets Desk, which sits at the heart of the global financial system as the world's ultimate and limitless provider of dollars. On behalf of policy makers, the Desk gathers market intelligence from all the major market participants, sifts through reams of internal data, and works behind the scenes keep the financial system intact. It is responsible for all of the Fed's market operations, from trillions in quantitative easing to hundreds of billions in repo and FX-swap loans. The financial crises of 2008 and 2020 abated only through the emergency interventions of the Desk.Joseph Wang spent five years studying the monetary system as a trader on the Desk. From that vantage point, Joseph saw firsthand how the Fed operates and how the financial system really works. This book is a distillation of his experience that aims to educate and demystify. After reading this book, you will understand how money is created, how the global dollar system is structured, and how it all fits into the broader financial system.The views in this book do not necessarily reflect those of the Federal Reserve Bank of New York or the Federal Reserve System.

    We need a brand new way to take it all in. 'Information is Beautiful' transforms the ideas surrounding and swamping us into graphs and maps that anyone can follow at a single glance.

    At a summer tea party in Cambridge, England, a guest states that tea poured into milk tastes different from milk poured into tea. Her notion is shouted down by the scientific minds of the group. But one man, Ronald Fisher, proposes to scientifically test the hypothesis. There is no better person to conduct such an experiment, for Fisher is a pioneer in the field of statistics.The Lady Tasting Tea spotlights not only Fisher's theories but also the revolutionary ideas of dozens of men and women which affect our modern everyday lives. Writing with verve and wit, David Salsburg traces breakthroughs ranging from the rise and fall of Karl Pearson's theories to the methods of quality control that rebuilt postwar Japan's economy, including a pivotal early study on the capacity of a small beer cask at the Guinness brewing factory. Brimming with intriguing tidbits and colorful characters, The Lady Tasting Tea salutes the spirit of those who dared to look at the world in a new way.

    Investors traditionally view low-risk stocks as safe but unprofitable, but this old canard is based on a flawed premise; it fails to see beyond the monthly horizon, and ignores compounding returns. This book updates the thinking and brings reality to modelling to show how low-risk stocks actually outperform high-risk stocks by an order of magnitude. Easy to read and easy to implement, the plan presented here will help you construct a portfolio that delivers higher returns per unit of risk, and explains how to achieve excellent investment results over the long term.Do you still believe that investors are rewarded for bearing risk, and that the higher the risk, the greater the reward? That old axiom is holding you back, and it is time to start seeing the whole picture. This book shows you, through deep historical simulation, how to reap the rewards of smarter investing.Learn how and why low-risk, low-volatility stocks beat the market Discover the formula that outperforms Greenblatt's Construct your own low-risk portfolio Select the right ETF or low-risk fund to manage your money Great returns and lower risk sound like a winning combination -- what happens once everyone is doing it? The beauty of the low-risk strategy is that it continues to work even after the paradox is widely known; long-term investment success is possible for anyone who can shake off the entrenched wisdom and go low-risk. High Returns from Low Risk provides the proof, model and strategy to reign in your exposure while raking in the profit.

    Author Jigar Shah, internationally recognized for revolutionizing the now multi-billion-dollar solar energy industry, outlines how entrepreneurs and investors can unlock the massive potential that climate change represents. Shah argues that, while new technical innovation is valuable, deployment of existing technologies are the key to reaching our near-term climate targets. Rather than waiting for yet to be developed technology, business model innovation is the key to attract mainstream capital and unlock transformational change. Shah makes a compelling case for reaching our 2020 climate change goals through 100,000 companies worldwide, each generating $100 million in sales. Unlocking our next economy will be driven by thousands of companies deploying existing clean and resource-efficient technologies in electricity-supply (like solar), transportation, building materials, industry, forestry, waste, and agriculture. Shah is not alone; according to the International Energy Agency, and others, $10 trillion can be invested profitably—today—in the world’s existing technologies, making Shah’s plan of 100,000 companies each generating $100 million in sales a reality in catalyzing a new economy in the process. Creating Climate Wealth is also the personal story of Shah’s journey through the solar industry and the founding of SunEdison, the world’s largest solar energy company. Through business model innovations, SunEdison helped trigger the multi-billion dollar solar energy services industry. Shah’s revolutionary approach has been emulated throughout the solar industry. But perhaps more important, it is also being adapted for other industrial sectors like agriculture and transportation – unlocking incredible new revenue streams, creating hundreds of thousands of jobs, and positively transforming the planet on a global level. This implementation of business-based solutions to solve complex social problems represents a new economic movement; driven by “Impact Investments.” Impact Investments are changing the world for the better, promoting development and economic growth, and encouraging local entrepreneurship. Unlocking these opportunities represent the largest wealth creation opportunity of our generation. Whether you are interested in climate change, poverty alleviation, or just promoting projects that make financial sense, this book is for you. Jigar Shah provides a proven roadmap to understanding the Impact Economy, and creating the lasting changes that will improve our world for future generations.

    Trading Bases explains how he did it. After the fall of Lehman Brothers, Joe Peta was out of a job. He found a new one but lost that, too, when an ambulance mowed him down. In search of a way to cheer himself up while he recuperated in a wheelchair, Peta started watching baseball again, as he had growing up. That’s when inspiration hit: Why not apply his outstanding risk-analysis skills to improve on sabermetrics, the method made famous by Moneyball—and beat the only market in town, the Vegas betting line? Why not treat MLB like the S&P 500? In Trading Bases, Peta shows how to subtract luck—in particular “cluster luck,” as he puts it—from a team’s statistics to best predict how it will perform in the next game and over the whole season. His baseball “hedge fund” returned an astounding 41 percent in 2011—and has never been down more than 5 percent. Peta takes readers to the ballpark in San Francisco, trading floors and baseball bars in New York, and sports books in Vegas, all while tracing the progress of his wagers. Often humorous, occasionally touching, and with a wink toward the sheer implausibility of the whole project, Trading Bases is all about the love of critical reasoning, trading cultures, risk management, and baseball. And not necessarily in that order.

    Len Fisher turns his attention to the science of cooperation in his lively and thought-provoking book. Fisher shows how the modern science of game theory has helped biologists to understand the evolution of cooperation in nature, and investigates how we might apply those lessons to our own society. In a series of experiments that take him from the polite confines of an English dinner party to crowded supermarkets, congested Indian roads, and the wilds of outback Australia, not to mention baseball strategies and the intricacies of quantum mechanics, Fisher sheds light on the problem of global cooperation. The outcomes are sometimes hilarious, sometimes alarming, but always revealing. A witty romp through a serious science, Rock, Paper, Scissors will both teach and delight anyone interested in what it what it takes to get people to work together.

    What if everything in life could be reduced to a simple formula? What if numbers were able to tell us which partners we were best matched with – not just in terms of attractiveness, but for a long-term committed marriage? Or if they could say which films would be the biggest hits at the box office, and what changes could be made to those films to make them even more successful? Or even who out of us is likely to commit certain crimes, and when? This may sound like the world of science-fiction, but in fact it is just the tip of the iceberg in a world that is increasingly ruled by complex algorithms and neural networks.In The Formula, Luke Dormehl takes you inside the world of numbers, asking how we came to believe in the all-conquering power of algorithms; introducing the mathematicians, artificial intelligence experts and Silicon Valley entrepreneurs who are shaping this brave new world, and ultimately asking how we survive in an era where numbers can sometimes seem to create as many problems as they solve.
