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

The face of the pedestrian safety crisis looks a lot like Ignacio Duarte-Rodriguez. The 77-year old grandfather was struck in a hit-and-run crash while trying to cross a high-speed, six-lane road without crosswalks near his son’s home in Phoenix, Arizona. He was one of the more than 6,000 people killed while walking in America in 2018. In the last ten years, there has been a 50 percent increase in pedestrian deaths. The tragedy of traffic violence has barely registered with the media and wider culture. Disproportionately the victims are like Duarte-Rodriguez—immigrants, the poor, and people of color. They have largely been blamed and forgotten. In Right of Way, journalist Angie Schmitt shows us that deaths like Duarte-Rodriguez’s are not unavoidable “accidents.” They don’t happen because of jaywalking or distracted walking. They are predictable, occurring in stark geographic patterns that tell a story about systemic inequality. These deaths are the forgotten faces of an increasingly urgent public-health crisis that we have the tools, but not the will, to solve. Schmitt examines the possible causes of the increase in pedestrian deaths as well as programs and movements that are beginning to respond to the epidemic. Her investigation unveils why pedestrians are dying—and she demands action. Right of Way is a call to reframe the problem, acknowledge the role of racism and classism in the public response to these deaths, and energize advocacy around road safety. Ultimately, Schmitt argues that we need improvements in infrastructure and changes to policy to save lives. Right of Way unveils a crisis that is rooted in both inequality and the undeterred reign of the automobile in our cities. It challenges us to imagine and demand safer and more equitable cities, where no one is expendable.

Book Description

Michael Lewis’s instant classic may be “the most influential book on sports ever written” (People), but “you need know absolutely nothing about baseball to appreciate the wit, snap, economy and incisiveness of [Lewis’s] thoughts about it” (Janet Maslin, New York Times). One of GQ's 50 Best Books of Literary Journalism of the 21st Century Just before the 2002 season opens, the Oakland Athletics must relinquish its three most prominent (and expensive) players and is written off by just about everyone—but then comes roaring back to challenge the American League record for consecutive wins. How did one of the poorest teams in baseball win so many games? In a quest to discover the answer, Michael Lewis delivers not only “the single most influential baseball book ever” (Rob Neyer, Slate) but also what “may be the best book ever written on business” (Weekly Standard). Lewis first looks to all the logical places—the front offices of major league teams, the coaches, the minds of brilliant players—but discovers the real jackpot is a cache of numbers?numbers!?collected over the years by a strange brotherhood of amateur baseball enthusiasts: software engineers, statisticians, Wall Street analysts, lawyers, and physics professors. What these numbers prove is that the traditional yardsticks of success for players and teams are fatally flawed. Even the box score misleads us by ignoring the crucial importance of the humble base-on-balls. This information had been around for years, and nobody inside Major League Baseball paid it any mind. And then came Billy Beane, general manager of the Oakland Athletics. He paid attention to those numbers?with the second-lowest payroll in baseball at his disposal he had to?to conduct an astonishing experiment in finding and fielding a team that nobody else wanted. In a narrative full of fabulous characters and brilliant excursions into the unexpected, Michael Lewis shows us how and why the new baseball knowledge works. He also sets up a sly and hilarious morality tale: Big Money, like Goliath, is always supposed to win . . . how can we not cheer for David?

Book Description

New York Times–Bestselling Author: “Brings Dave Barry-style humor to an illuminating book on what is wrong with American democracy—and how to put it right.” —The Washington Post The democracy you live in today is different—completely different—from the democracy you were born into. You probably don't realize just how radically your republic has been altered during your lifetime. Yet more than any policy issue, political trend, or even Donald Trump himself, our redesigned system of government is responsible for the peril America faces today. What explains the gap between what We, the People want and what our elected leaders do? How can we fix our politics before it's too late? And how can we truly understand the state of our democracy without wanting to crawl under a rock? That’s what former Obama speechwriter David Litt set out to answer. Poking into forgotten corners of history, translating political science into plain English, and traveling the country to meet experts and activists, Litt explains how the world’s greatest experiment in democracy went awry. (He also tries to crash a party at Mitch McConnell’s former frat house. It goes poorly.) The result is something you might not have thought possible: an unexpectedly funny page-turner about the political process. You’ll meet the Supreme Court justice charged with murder, learn how James Madison’s college roommate broke the Senate, encounter a citrus thief who embodies what’s wrong with our elections, and join Belle the bill as she tries to become a law (a quest far more harrowing than the one in Schoolhouse Rock!). Yet despite his clear-eyed assessment of the dangers we face, Litt remains audaciously optimistic. He offers a to-do list of bold yet achievable changes—a blueprint for restoring the balance of power in America. “In the book’s strongest contribution, Litt shows how radically our democracy has been altered in recent decades . . . [making] the case that nearly all of these negative trends are occurring by design.” —The Washington Post “Wry, quickly readable, yet informed.” —The Atlantic “Equal parts how-to, historical, and hilarious.” —Keegan-Michael Key

Book Description

A book from the stand-up mathematician that makes math fun again! Math is boring, says the mathematician and comedian Matt Parker. Part of the problem may be the way the subject is taught, but it's also true that we all, to a greater or lesser extent, find math difficult and counterintuitive. This counterintuitiveness is actually part of the point, argues Parker: the extraordinary thing about math is that it allows us to access logic and ideas beyond what our brains can instinctively do—through its logical tools we are able to reach beyond our innate abilities and grasp more and more abstract concepts. In the absorbing and exhilarating Things to Make and Do in the Fourth Dimension, Parker sets out to convince his readers to revisit the very math that put them off the subject as fourteen-year-olds. Starting with the foundations of math familiar from school (numbers, geometry, and algebra), he reveals how it is possible to climb all the way up to the topology and to four-dimensional shapes, and from there to infinity—and slightly beyond. Both playful and sophisticated, Things to Make and Do in the Fourth Dimension is filled with captivating games and puzzles, a buffet of optional hands-on activities that entices us to take pleasure in math that is normally only available to those studying at a university level. Things to Make and Do in the Fourth Dimension invites us to re-learn much of what we missed in school and, this time, to be utterly enthralled by it.

Book Description

A Dominican-born academic tells the story of how the Great Books transformed his life—and why they have the power to speak to people of all backgrounds What is the value of a liberal education? Traditionally characterized by a rigorous engagement with the classics of Western thought and literature, this approach to education is all but extinct in American universities, replaced by flexible distribution requirements and ever-narrower academic specialization. Many academics attack the very idea of a Western canon as chauvinistic, while the general public increasingly doubts the value of the humanities. In Rescuing Socrates, Dominican-born American academic Roosevelt Montás tells the story of how a liberal education transformed his life, and offers an intimate account of the relevance of the Great Books today, especially to members of historically marginalized communities. Montás emigrated from the Dominican Republic to Queens, New York, when he was twelve and encountered the Western classics as an undergraduate in Columbia University’s renowned Core Curriculum, one of America’s last remaining Great Books programs. The experience changed his life and determined his career—he went on to earn a PhD in English and comparative literature, serve as director of Columbia’s Center for the Core Curriculum, and start a Great Books program for low-income high school students who aspire to be the first in their families to attend college. Weaving together memoir and literary reflection, Rescuing Socrates describes how four authors—Plato, Augustine, Freud, and Gandhi—had a profound impact on Montás’s life. In doing so, the book drives home what it’s like to experience a liberal education—and why it can still remake lives.
