Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

    They make us capable of doing great things. And according to Marcus du Sautoy, math is the very art of the shortcut.Thinking Better is a celebration of how math lets us do more with less. Du Sautoy explores how diagramming revolutionized therapy, why calculus is the greatest shortcut ever invented, whether you must really practice for ten thousand hours to become a concert violinist, and why shortcuts give us an advantage over even the most powerful AI. Throughout, we meet artists, scientists, and entrepreneurs who use mathematical shortcuts to change the world.Delightful, illuminating, and above all practical, Thinking Better is for anyone who has wondered why you should waste time climbing the mountain when you could go around it much faster.

    There was a time when the stock market was a mechanism for growing businesses to raise money, playing a large role in the industrial revolution-boosting America to a global superpower. Today the stock market has morphed into a high-tech system of fluctuating arbitrary numbers which are used by individuals and industries alike to find profit opportunities by placing bets, masqueraded as sophisticated financial maneuvers with fancy labels and acronyms. Nowhere is this more evident than with the tendencies observed today. There is a shocking trend by today's Millennial generation to shamelessly and unapologetically find ways to use the stock market to place very high-risk bets. And unlike formal Wall Street investment institutions, these gamblers, of sorts, don't attempt to disguise the game: they are proud to call Wall Street a casino. Jaime Rogozinski combs through various elements of how reckless investors play Wall Street similar to a casino. He illustrates these often in playful ways, using entertaining and compelling real-world anecdotes. His stories are taken straight from Reddit's r/wallstreetbets community which Jaime founded in 2012, and currently has more than 800,000 followers in addition to 3 million unique visitors a month. WallStreetBets is a forum based gathering where people are notoriously known for taking a brazen and public approach at gambling with the stock market.

    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.

    If you’ve ever sought a job or hired someone, applied to college or guided your child into a good kindergarten, asked someone out on a date or been asked out, you’ve participated in a kind of market. Most of the study of economics deals with commodity markets, where the price of a good connects sellers and buyers. But what about other kinds of “goods,” like a spot in the Yale freshman class or a position at Google? This is the territory of matching markets, where “sellers” and “buyers” must choose each other, and price isn’t the only factor determining who gets what.Alvin E. Roth is one of the world’s leading experts on matching markets. He has even designed several of them, including the exchange that places medical students in residencies and the system that increases the number of kidney transplants by better matching donors to patients. In Who Gets What — And Why, Roth reveals the matching markets hidden around us and shows how to recognize a good match and make smarter, more confident decisions.

    In this lively and groundbreaking new book, economist Ian Ayres shows how today's best and brightest organizations are analyzing massive databases at lightening speed to provide greater insights into human behavior. They are the Super Crunchers. From internet sites like Google and Amazon that know your tastes better than you do, to a physician's diagnosis and your child's education, to boardrooms and government agencies, this new breed of decision makers are calling the shots. And they are delivering staggeringly accurate results. How can a football coach evaluate a player without ever seeing him play? Want to know whether the price of an airline ticket will go up or down before you buy? How can a formula outpredict wine experts in determining the best vintages? Super crunchers have the answers. In this brave new world of equation versus expertise, Ayres shows us the benefits and risks, who loses and who wins, and how super crunching can be used to help, not manipulate us.Gone are the days of solely relying on intuition to make decisions. No businessperson, consumer, or student who wants to stay ahead of the curve should make another keystroke without reading Super Crunchers.

    He had gambled and won, but his volatility and reluctance to pay his debts were making him enemies. He lived the high life as only a young man would, buying luxury homes, private jets, sports cars and football teams, and splurging massively to build a horseracing empire.But Tinkler’s dreams had extended beyond even his resources, and his business model worked only in a rising market. When coal prices slumped in 2012, Tinkler had no cash flow to service his massive borrowings and no allies to help him recover. Within months he was trying desperately to stave off his creditors, large and small, and fighting to save his businesses and his fortune.In this impressive biography, leading business writer Paddy Manning tells the story of Tinkler’s meteoric rise to wealth, and captures the drama of his equally rapid downfall.‘Some might see it as a handbook on how to go from broke to billionaire in a matter of years … Others might see it as a morality tale about the canker at the heart of the consumerist, aspirational politics peddled by our leaders for the past few decades.’ —Sydney Morning Herald‘Paddy Manning’s Boganaire: The Rise and Fall of Nathan Tinkler is a rollicking tale, which works on our sense of schadenfreude.’ —Chloe Hooper, the Monthly‘Boganaire is much more than a book for readers of business literature. It provides an insight into a bigger and more important subject than Nathan Tinkler: it shows how the easy prosperity from resource riches might be changing our culture and values for the worse.’ — the Australian‘The richly detailed book lays Tinkler’s life bare, from his early days working in Newcastle’s coal mines through to his triumphant deals with Macarthur Coal and Whitehaven, and his spectacular fall from grace.’ —BRWPaddy Manning is one of Australia’s most respected journalists, with fifteen years’ experience including a decade on the business desks of the Sydney Morning Herald, the Australian Financial Review and the Australian – a period in which he was highly commended in the business category of the Walkley Awards and was a three-time category winner in the prestigious Citigroup Journalism Awards for Excellence. His first book, What the Frack: everything you need to know about coal seam gas, was published in 2012.
