Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that Pluto was a planet. For decades, we were convinced that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing.   But it turns out there’s an order to the state of knowledge, an explanation for how we know what we know. Samuel Arbesman is an expert in the field of scientometrics—literally the science of science. Knowl­edge in most fields evolves systematically and predict­ably, and this evolution unfolds in a fascinating way that can have a powerful impact on our lives.   Doctors with a rough idea of when their knowl­edge is likely to expire can be better equipped to keep up with the latest research. Companies and govern­ments that understand how long new discoveries take to develop can improve decisions about allocating resources. And by tracing how and when language changes, each of us can better bridge gen­erational gaps in slang and dialect.   Just as we know that a chunk of uranium can break down in a measurable amount of time—a radioactive half-life—so too any given field’s change in knowledge can be measured concretely. We can know when facts in aggregate are obsolete, the rate at which new facts are created, and even how facts spread.   Arbesman takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries. He shows that much of what we know consists of “mesofacts”—facts that change at a middle timescale, often over a single human lifetime. Throughout, he of­fers intriguing examples about the face of knowledge: what English majors can learn from a statistical analysis of The Canterbury Tales, why it’s so hard to measure a mountain, and why so many parents still tell kids to eat their spinach because it’s rich in iron.   The Half-life of Facts is a riveting journey into the counterintuitive fabric of knowledge. It can help us find new ways to measure the world while accepting the limits of how much we can know with certainty.

    Rest is something to do when the important things are done-but they are never done. Looking at different forms of rest, from sleep to vacation, Silicon Valley futurist and business consultant Alex Soojung-Kim Pang dispels the myth that the harder we work the better the outcome. He combines rigorous scientific research with a rich array of examples of writers, painters, and thinkers---from Darwin to Stephen King---to challenge our tendency to see work and relaxation as antithetical. "Deliberate rest," as Pang calls it, is the true key to productivity, and will give us more energy, sharper ideas, and a better life. Rest offers a roadmap to rediscovering the importance of rest in our lives, and a convincing argument that we need to relax more if we actually want to get more done.

    He solidified his standing as the nation's foremost political forecaster with his near perfect prediction of the 2012 election. Silver is the founder and editor in chief of FiveThirtyEight.com. Drawing on his own groundbreaking work, Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the "prediction paradox": The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.In keeping with his own aim to seek truth from data, Silver visits the most successful forecasters in a range of areas, from hurricanes to baseball, from the poker table to the stock market, from Capitol Hill to the NBA. He explains and evaluates how these forecasters think and what bonds they share. What lies behind their success? Are they good-or just lucky? What patterns have they unraveled? And are their forecasts really right? He explores unanticipated commonalities and exposes unexpected juxtapositions. And sometimes, it is not so much how good a prediction is in an absolute sense that matters but how good it is relative to the competition. In other cases, prediction is still a very rudimentary-and dangerous-science.Silver observes that the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.

    Into this creative chaos came Google with its dazzling mission—“To organize the world’s information and make it universally accessible”—and its much-quoted motto, “Don’t be evil.” In this provocative book, Siva Vaidhyanathan examines the ways we have used and embraced Google—and the growing resistance to its expansion across the globe. He exposes the dark side of our Google fantasies, raising red flags about issues of intellectual property and the much-touted Google Book Search. He assesses Google’s global impact, particularly in China, and explains the insidious effect of Googlization on the way we think. Finally, Vaidhyanathan proposes the construction of an Internet ecosystem designed to benefit the whole world and keep one brilliant and powerful company from falling into the “evil” it pledged to avoid.

    In the 1970s, Pollack had excelled as one of Yale’s first two women to earn a bachelor of science degree in physics. But, isolated, lacking in confidence, and starved for encouragement, she abandoned her lifelong dream of becoming a theoretical physicist. Years later, she thought back on her experiences and wondered what had changed in the intervening decades, and what challenges remained. Based on six years of interviewing dozens of teachers and students and reviewing studies on gender bias, The Only Woman in the Room is an illuminating exploration of the cultural, social, psychological, and institutional barriers confronting women in the STEM disciplines. Pollack brings to light the struggles that women in the sciences are often hesitant to admit and provides hope that changing attitudes and behaviors can bring more women into fields in which they remain, to this day, seriously underrepresented.Eileen Pollack is the author of the novels Breaking and Entering (a New York Times Editor’s Choice selection) and Paradise, New York, as well as two collections of short fiction, an award-winning book of nonfiction, and two creative-nonfiction textbooks. Her work has appeared in Best American Essays and Best American Short Stories. She is a professor on the faculty of the Helen Zell MFA Program in Creative Writing at the University of Michigan. She divides her time between Manhattan and Ann Arbor, Michigan.

    Using a unique systems approach, it brings together an extraordinary breadth of information into a highly accessible, easy-to-read text that clarifies the complexities of health care organization and finance, while presenting a solid overview of how the various components fit together.

    If you master this skill, you'll achieve extraordinary results.Deep work is the ability to focus without distraction on a cognitively demanding task. It's a skill that allows you to quickly master complicated information and produce better results in less time. Deep work will make you better at what you do and provide the sense of true fulfillment that comes from craftsmanship. In short, deep work is like a super power in our increasingly competitive twenty-first century economy. And yet, most people have lost the ability to go deep-spending their days instead in a frantic blur of e-mail and social media, not even realizing there's a better way.In Deep Work, author and professor Cal Newport flips the narrative on impact in a connected age. Instead of arguing distraction is bad, he instead celebrates the power of its opposite. Dividing this book into two parts, he first makes the case that in almost any profession, cultivating a deep work ethic will produce massive benefits. He then presents a rigorous training regimen, presented as a series of four "rules," for transforming your mind and habits to support this skill.A mix of cultural criticism and actionable advice, Deep Work takes the reader on a journey through memorable stories-from Carl Jung building a stone tower in the woods to focus his mind, to a social media pioneer buying a round-trip business class ticket to Tokyo to write a book free from distraction in the air-and no-nonsense advice, such as the claim that most serious professionals should quit social media and that you should practice being bored. Deep Work is an indispensable guide to anyone seeking focused success in a distracted world.
