Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem.Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed.Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked."Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 black-and-white illustrations.

    Friendships and relationships can suffer. Bad decisions at the inception of a promising venture lay the foundations for its eventual ruin. The Founder's Dilemmas is the first book to examine the early decisions by entrepreneurs that can make or break a startup and its team.Drawing on a decade of research, Noam Wasserman reveals the common pitfalls founders face and how to avoid them. He looks at whether it is a good idea to cofound with friends or relatives, how and when to split the equity within the founding team, and how to recognize when a successful founder-CEO should exit or be fired. Wasserman explains how to anticipate, avoid, or recover from disastrous mistakes that can splinter a founding team, strip founders of control, and leave founders without a financial payoff for their hard work and innovative ideas. He highlights the need at each step to strike a careful balance between controlling the startup and attracting the best resources to grow it, and demonstrates why the easy short-term choice is often the most perilous in the long term. The Founder's Dilemmas draws on the inside stories of founders like Evan Williams of Twitter and Tim Westergren of Pandora, while mining quantitative data on almost ten thousand founders.People problems are the leading cause of failure in startups. This book offers solutions.

    The book jump-started the international “seduction community,” and made Strauss a household name—revered or notorious—among single men and women alike.But the experience of writing The Game also transformed Strauss into a man who could have what every man wants: the ability to date or have casual sex with almost every woman he met. The results were heady, to be sure. But they also conditioned him to view the world as a kind of constant parade of women, sex, and opportunity—with intimacy and long-term commitment taking a back seat. That is, until he met the woman who forced him to choose between herself and the parade. The choice was not only difficult, it was wrenching. It forced him deep into his past, to confront not only the moral dimensions of his pickup lifestyle, but also a wrenching mystery in his childhood that shaped the man that he became. It sent him into extremes of behavior that exposed just how conflicted his life had become. And it made him question everything he knew about himself, and about the way men and women live with and without each other.He would never be the same again.Searingly honest, compulsively readable, this book may have the same effect on you.

    Yet brain scientists have uncovered details every business leader, parent, and teacher should know—like the need for physical activity to get your brain working its best.How do we learn? What exactly do sleep and stress do to our brains? Why is multi-tasking a myth? Why is it so easy to forget—and so important to repeat new knowledge? Is it true that men and women have different brains?In Brain Rules, Dr. John Medina, a molecular biologist, shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work. In each chapter, he describes a brain rule—what scientists know for sure about how our brains work—and then offers transformative ideas for our daily lives.Medina’s fascinating stories and infectious sense of humor breathe life into brain science.

    Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life.Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking.While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner.In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

    Even companies committed to jabbing-patiently engaging with customers to build the relationships so crucial to successful social media campaigns-still yearn to land the powerful, bruising swing that will knock out their opponent or their customer's resistance in one tooth-spritzing, killer blow. Right hooks, after all, convert traffic to sales. They easily show results and ROI. Except when they don't.In the same passionate, street-wise style readers have come to expect, Gary Vaynerchuk is on a mission to improve marketers' right hooks by changing the way they fight to make their customers happy, and ultimately to compete. Thanks to the massive change and proliferation in social media platforms in the last four years, the winning combination of jabs and right hooks is different now. Communication is still key, but context matters more than ever. It's not just about developing high-quality content, but developing high-quality content perfectly adapted to specific social media platforms and mobile devices-content tailor-made for Facebook, YouTube, Instagram, Pinterest, Twitter, and Tumblr. A mash-up of the best elements of Crush It! and The Thank You Economy with a 2013 spin, here is a blueprint to social media marketing strategies that really works.

    Sandel takes up one of the biggest ethical questions of our time: Isn't there something wrong with a world in which everything is for sale? If so, how can we prevent market values from reaching into spheres of life where they don't belong? What are the moral limits of markets?In recent decades, market values have crowded out nonmarket norms in almost every aspect of life. Without quite realizing it, Sandel argues, we have drifted from having a market economy to being a market society.In Justice, an international bestseller, Sandel showed himself to be a master at illuminating, with clarity and verve, the hard moral questions we confront in our everyday lives. Now, in What Money Can't Buy, he provokes a debate that's been missing in our market-driven age: What is the proper role of markets in a democratic society, and how can we protect the moral and civic goods that markets do not honor and money cannot buy?

    Triggers shows us how to break that cycle and enact meaningful change.In Triggers, renown executive coach and psychologist Marshall Goldsmith discusses the emotional triggers that set off a reaction or a behavior in us that often works to our detriment. Do you find that at times you suddenly become defensive or enraged by an idle comment from a colleague? Or that your temper rises when another car cuts you off in traffic? Your reactions don’t occur in a vacuum. They are the result of emotional and psychological triggers that often happen only in specific settings—at meetings, or in competitive situations, or with a specific person who rubs you the wrong way, or when you feel under particular pressure. Being able to recognize those triggers and understand how the environment affects our behavior is key to controlling our responses and managing others at work and in life. Make no mistake—change is hard. And the starting point is the willingness to accept help, and the desire to change. This book will show you how.Over the course of this book, Marshall explores the power of active questions to get us to take responsibility for our actions—and our failure to act. Questions such as “Did I do my best to make progress toward my goal?” “Did I work hard at being fully engaged?” He discusses the importance of structure in effecting permanent change. Because, he points out, change is hard, and without a structure to keep us on track, we inevitably relapse and fall back.Filled with illuminating stories from Marshall’s work with some of the most accomplished executives and leaders in America, Triggers shows readers how to achieve meaningful and sustained change that will allow us to open our imaginations and escape the rigidity of binary thinking.
