. . and then broke? How would you survive? Could you improve on humanity's original timeline? And how hard would it be to domesticate a giant wombat? With this book as your guide, you'll survive--and thrive--in any period in Earth's history. Bestselling author and time-travel enthusiast Ryan North shows you how to invent all the modern conveniences we take for granted--from first principles. This illustrated manual contains all the science, engineering, art, philosophy, facts, and figures required for even the most clueless time traveler to build a civilization from the ground up. Deeply researched, irreverent, and significantly more fun than being eaten by a saber-toothed tiger, How to Invent Everything will make you smarter, more competent, and completely prepared to become the most important and influential person ever.

    Who thought up paper money? What was the secret element that made the Gutenberg printing press possible? And what is the connection between The Da Vinci Code and the collapse of Lehman Brothers? Fifty Inventions That Shaped the Modern Economy paints an epic picture of change in an intimate way by telling the stories of the tools, people, and ideas that had far-reaching consequences for all of us. From the plough to artificial intelligence, from Gillette’s disposable razor to IKEA’s Billy bookcase, bestselling author and Financial Times columnist Tim Harford recounts each invention’s own curious, surprising, and memorable story. Invention by invention, Harford reflects on how we got here and where we might go next. He lays bare often unexpected connections: how the bar code undermined family corner stores, and why the gramophone widened inequality. In the process, he introduces characters who developed some of these inventions, profited from them, and were ruined by them, as he traces the principles that helped explain their transformative effects. The result is a wise and witty book of history, economics, and biography.

    Thorough in its coverage of basic theory, from the lever and inclined plane to internal combustion engines and power trains, it requires nothing more than an understanding of the most elementary mathematics. Beginning with the simplest of machines — the lever — the text proceeds to discussions of the block and tackle (pulleys and hoists), wheel and axle, the inclined plane and the wedge, the screw, and different types of gears (simple, spur, bevel, herringbone, spiral, worm, etc.). A chapter on the concept of work discusses the measurement of work, friction, and efficiency; this is followed by investigations of power, force, and pressure, with explanations of the uses of scales, balances, gauges, and barometers. The fundamentals of hydrostatic and hydraulic machines (such as the hydraulic braking system and the hydraulic press) are discussed in detail. The remaining chapters cover machine elements (bearings and springs), basic mechanisms (gear differential, couplings, cams, clutches), the internal combustion engine and power trains (including explanations of various transmission systems — synchromesh, auxiliary, etc.). Every concept is clearly defined, and discussions always build easily from elementary theory to specific applications familiar to anyone with the slightest interest in mechanics. Important concepts, machine components, and techniques are clearly illustrated in more than 200 diagrams, drawings, and cross-sections that reveal inner workings — all of these help to clarify even further an already clear and well-organized presentation. Although it was originally designed for use in U.S. Naval Training Schools, this book can be used to great advantage as a basic text in mechanical engineering in standard technical schools, and it will be immensely valuable even to lay readers who desire a basic knowledge of mechanics.

    And an absolute must for everyone with a learner's permit. Former Top Gear Stig and professional driver Ben Collins shares expert skills culled from a twenty year career as one of the best drivers in the world, famous for racing in the Le Mans series and NASCAR, piloting the Batmobile, and dodging bullets with James Bond. Refined over thousands of hours of elite-level performance in the physics of driving, his philosophy results in greater control and safer, more efficient and fun driving for all skill levels.

    More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity--and possibly dilution.This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker's Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

    We will no longer be passive bystanders to the dance of the universe, but will become creative choreographers of matter, life, and intelligence.The first section of Visions presents a shocking look at a cyber-world infiltrated by millions of tiny intelligence systems. Part two illustrates how the decoding of DNA's genetic structure will allow humans the "godlike ability to manipulate life almost at will." Finally, VISIONS focuses on the future of quantum physics, in which physicists will perfect new ways to manipulate matter and harness the cosmic energy of the universe.What makes Michio Kaku's vision of the science of the future so compelling--and so different from the mere forecasts of most thinkers--is that it is based on the groundbreaking research taking place in labs today, as well as the consensus of over 150 of Kaku's scientific colleagues. Science, for all its breathtaking change, evolves slowly; we can accurately predict, asserts Kaku, what the direction of science will be, based on the paths that are being forged today.A thrilling, unique narrative that brings together the thinking of many of the world's most accomplished scientists to explore the world of the future, Visions is science writing at its best.

    This is not a "how-to" book in any sense. Korn wants to get at the why of craft, in particular, and at the satisfactions of creative work, in general to understand their essential nature. How does the making of objects both reflect and refine our own identities? What is it about craft and creative work that makes them so rewarding? What is the nature of those rewards? How do the products of creative work inform society?

    Petit is the perfect teacher" in this fascinating, educational volume on knot-tying--an art and science that has held civilization together (The Wall Street Journal).Philippe Petit is known for his astounding feat of daring when, on August 7, 1974, he stepped out on a wire illegally rigged between the World Trade Center's twin towers in New York City. But beyond his balance, courage, and showmanship, there was one thing Petit had to be absolutely certain of--his knots. Without the confidence that his knots would hold, he never would have left the ground. In fact, while most of us don't think about them beyond tying our shoelaces, the humble knot is crucial in countless contexts, from sailing to sports to industrial safety to art, agriculture, and more.In this truly unique book, Petit offers a guide to tying over sixty of his essential knots, with practical sketches illustrating his methods and clear tying instructions. Filled with photos in which special knots were used during spectacular high-wire walks, quirky knot trivia, personal anecdotes, helpful tips, magic tricks, and special tying challenges, Why Knot? will entertain and educate readers of all ages."In reading Philippe's book we are cogently reminded that without the ability to secure a rope, or tether a goat, or make fast the sheets of a galley, much of the civilization that we take for granted would disappear as easily as a slipknot in the hands of a Vegas conjuror." --Sting, musician and activist"His descriptions are clear, he deploys humor frequently and he makes his points with anecdotes that are colorful and memorable. Explaining the purpose and creation of knots and thanks to those flawless drawings Mr. Petit earns perfect marks." --The Wall Street Journal
