Book Description
A mathematical journey through the most fascinating problems of extremes and how to solve them What is the best way to photograph a speeding bullet? How can lost hikers find their way out of a forest? Why does light move through glass in the least amount of time possible? When Least Is Best combines the mathematical history of extrema with contemporary examples to answer these intriguing questions and more. Paul Nahin shows how life often works at the extremes—with values becoming as small (or as large) as possible—and he considers how mathematicians over the centuries, including Descartes, Fermat, and Kepler, have grappled with these problems of minima and maxima. Throughout, Nahin examines entertaining conundrums, such as how to build the shortest bridge possible between two towns, how to vary speed during a race, and how to make the perfect basketball shot. Moving from medieval writings and modern calculus to the field of optimization, the engaging and witty explorations of When Least Is Best will delight math enthusiasts everywhere.

Book Description
The New York Times bestselling work of undercover reportage from our sharpest and most original social critic, with a new foreword by Matthew Desmond, author of Evicted Millions of Americans work full time, year round, for poverty-level wages. In 1998, Barbara Ehrenreich decided to join them. She was inspired in part by the rhetoric surrounding welfare reform, which promised that a job—any job—can be the ticket to a better life. But how does anyone survive, let alone prosper, on $6 an hour? To find out, Ehrenreich left her home, took the cheapest lodgings she could find, and accepted whatever jobs she was offered. Moving from Florida to Maine to Minnesota, she worked as a waitress, a hotel maid, a cleaning woman, a nursing-home aide, and a Wal-Mart sales clerk. She lived in trailer parks and crumbling residential motels. Very quickly, she discovered that no job is truly "unskilled," that even the lowliest occupations require exhausting mental and muscular effort. She also learned that one job is not enough; you need at least two if you int to live indoors. Nickel and Dimed reveals low-rent America in all its tenacity, anxiety, and surprising generosity—a land of Big Boxes, fast food, and a thousand desperate stratagems for survival. Read it for the smoldering clarity of Ehrenreich's perspective and for a rare view of how "prosperity" looks from the bottom. And now, in a new foreword, Matthew Desmond, author of Evicted: Poverty and Profit in the American City, explains why, twenty years on in America, Nickel and Dimed is more relevant than ever.

Book Description
Aimed at teaching mathematics students how to program using their knowledge of mathematics, the entire books emphasis is on "how to think" when programming. Three methods for constructing an algorithm or a program are used: manipulation and enrichment of existing code; use of recurrent sequences; deferral of code writing, in order to deal with one difficulty at a time. Many theorems are mathematically proved and programmed, and the text concludes with an explanation of how a compiler works and how to compile "by hand" little programs. Intended for anyone who thinks mathematically and wants to program and play with mathematics.

Book Description
NEW YORK TIMES BESTSELLER • The groundbreaking investigation of how the global elite's efforts to "change the world" preserve the status quo and obscure their role in causing the problems they later seek to solve. An essential read for understanding some of the egregious abuses of power that dominate today’s news. "Impassioned.... Entertaining reading.” —The Washington Post Anand Giridharadas takes us into the inner sanctums of a new gilded age, where the rich and powerful fight for equality and justice any way they can—except ways that threaten the social order and their position atop it. They rebrand themselves as saviors of the poor; they lavishly reward “thought leaders” who redefine “change” in ways that preserve the status quo; and they constantly seek to do more good, but never less harm. Giridharadas asks hard questions: Why, for example, should our gravest problems be solved by the unelected upper crust instead of the public institutions it erodes by lobbying and dodging taxes? His groundbreaking investigation has already forced a great, sorely needed reckoning among the world’s wealthiest and those they hover above, and it points toward an answer: Rather than rely on scraps from the winners, we must take on the grueling democratic work of building more robust, egalitarian institutions and truly changing the world—a call to action for elites and everyday citizens alike.

Book Description
THE LIFE-CHANGING NEW YORK TIMES BESTSELLER • MORE THAN TWO MILLION COPIES SOLD • Now in a 10th anniversary edition featuring a new introduction and bonus 21-day challenge. “Essentialism holds the keys to solving one of the great puzzles of life: How can we do less but accomplish more?”—Adam Grant, bestselling author of Think Again Essentialism isn’t about getting more done in less time. It’s about getting only the right things done. Have you ever found yourself stretched too thin? Are you often busy but not productive? Do you feel like your time is constantly being hijacked? If you answered yes to any of these, the way out is the Way of the Essentialist. Essentialism is more than a time-management technique. It is a systematic discipline for discerning what is absolutely essential, then eliminating everything that is not, so we can make the highest possible contribution toward the things that really matter. By forcing us to apply more selective criteria for where to spend our precious time and energy, the disciplined pursuit of less empowers us to reclaim control of our own choices, instead of giving others the implicit permission to choose for us. Essentialism is not one more thing to do. It’s a whole new way of doing less, but better, in every area of our lives. Join the millions of people who have used Essentialism to change their outlook on the world.
