Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge--from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool--the general principle--from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.Street-Fighting Mathematics will appear in print and online under a Creative Commons Noncommercial Share Alike license.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    . . . An extraordinary book.”—Anne Eisenberg, Scientific AmericanA companion to the man-made landscape that reveals how our industrial environment can be as dazzling as the natural world. Replete with the author's striking photographs, "Infrastructure" is a unique and spectacular guide, exploring all the major "ecosystems" of our modern industrial world, revealing what the structures are and why they're there, and uncovering beauty in unexpected places--awakening and fulfilling a curiosity you didn't know you had. Covering agriculture, resources, energy, communication, transportation, manufacturing, and waste, this is the "Book of Everything" for the industrial landscape. The objects that fill our everyday environment are streetlights, railroad tracks, antenna towers, highway overpasses, power lines, satellite dishes, and thousands of other manufactured items, many of them so familiar we hardly notice them. Larger and more exotic facilities have transformed vast tracts of the landscape: coal mines, nuclear power plants, grain elevators, oil refineries, and steel mills, to name a few. "Infrastructure" is a compelling and clear guide for those who want to explore and understand this mysterious world we've made for ourselves. 500 color illustrations.ContentsPreface1.

    The [Chithoni railway link] bridge was completed eleven weeks ahead of schedule and proved to be helpful to one and all.Two key railway projects changed the way India travels by train—the 760-km stretch of Konkan Railway and the Delhi Metro. Both the projects were up and running in seven years flat and the man in charge was Dr Elattuvalapil Sreedharan, popularly known as the Railway Man.

    And what aircraft they were. The sleek Comet, the first jet airliner. The awesome delta-winged Vulcan, an intercontinental bomber that could be thrown about the sky like a fighter. The Hawker Hunter, the most beautiful fighter-jet ever built and the Lightning, which could zoom ten miles above the clouds in a couple of minutes and whose pilots rated flying it as better than sex.How did Britain so lose the plot that today there is not a single aircraft manufacturer of any significance in the country? What became of the great industry of de Havilland or Handley Page? And what was it like to be alive in that marvellous post-war moment when innovative new British aircraft made their debut, and pilots were the rock stars of the age?James Hamilton-Paterson captures that season of glory in a compelling book that fuses his own memories of being a schoolboy plane spotter with a ruefully realistic history of British decline - its loss of self confidence and power. It is the story of great and charismatic machines and the men who flew them: heroes such as Bill Waterton, Neville Duke, John Derry and Bill Beaumont who took inconceivable risks, so that we could fly without a second thought.

    Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. Quanta, under editor-in-chief Thomas Lin, is the only popular publication that offers in-depth coverage of today's challenging, speculative, cutting-edge science. It communicates science by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.In the title story, Alice and Bob--beloved characters of various thought experiments in physics--grapple with gravitational forces, possible spaghettification, and a massive wall of fire as Alice jumps into a black hole. Another story considers whether the universe is impossible, in light of experimental results at the Large Hadron Collider. We learn about quantum reality and the mystery of quantum entanglement; explore the source of time's arrow; and witness a eureka moment when a quantum physicist exclaims: "Finally, we can understand why a cup of coffee equilibrates in a room." We reflect on humans' enormous skulls and the Brain Boom; consider the evolutionary benefits of loneliness; peel back the layers of the newest artificial-intelligence algorithms; follow the "battle for the heart and soul of physics"; and mourn the disappearance of the "diphoton bump," revealed to be a statistical fluctuation rather than a revolutionary new particle. These stories from Quanta give us a front-row seat to scientific discovery.ContributorsPhilip Ball, K. C.

Examples and applications invite students to solve problems and build their knowledge of electromagnetics. Application topics include: electric motors, transmission lines, waveguides, antenna arrays and radar systems.

    Professors Gary Marcus and Ernest Davis have spent their careers at the forefront of AI research and have witnessed some of the greatest milestones in the field, but they argue that a computer winning in games like Jeopardy and go does not signal that we are on the doorstep of fully autonomous cars or superintelligent machines. The achievements in the field thus far have occurred in closed systems with fixed sets of rules. These approaches are too narrow to achieve genuine intelligence. The world we live in is wildly complex and open-ended. How can we bridge this gap? What will the consequences be when we do? Marcus and Davis show us what we need to first accomplish before we get there and argue that if we are wise along the way, we won't need to worry about a future of machine overlords. If we heed their advice, humanity can create an AI that we can trust in our homes, our cars, and our doctor's offices. Reboot provides a lucid, clear-eyed assessment of the current science and offers an inspiring vision of what we can achieve and how AI can make our lives better.
