| back of napkin math: Guesstimation 2.0 Lawrence Weinstein, 2012-09-30 Simple and effective techniques for quickly estimating virtually anything Guesstimation 2.0 reveals the simple and effective techniques needed to estimate virtually anything—quickly—and illustrates them using an eclectic array of problems. A stimulating follow-up to Guesstimation, this is the must-have book for anyone preparing for a job interview in technology or finance, where more and more leading businesses test applicants using estimation questions just like these. The ability to guesstimate on your feet is an essential skill to have in today's world, whether you're trying to distinguish between a billion-dollar subsidy and a trillion-dollar stimulus, a megawatt wind turbine and a gigawatt nuclear plant, or parts-per-million and parts-per-billion contaminants. Lawrence Weinstein begins with a concise tutorial on how to solve these kinds of order of magnitude problems, and then invites readers to have a go themselves. The book features dozens of problems along with helpful hints and easy-to-understand solutions. It also includes appendixes containing useful formulas and more. Guesstimation 2.0 shows how to estimate everything from how closely you can orbit a neutron star without being pulled apart by gravity, to the fuel used to transport your food from the farm to the store, to the total length of all toilet paper used in the United States. It also enables readers to answer, once and for all, the most asked environmental question of our day: paper or plastic? |

| back of napkin math: Street-Fighting Mathematics Sanjoy Mahajan, 2010-03-05 An antidote to mathematical rigor mortis, teaching how to guess answers without needing a proof or an exact calculation. In problem solving, as in street fighting, rules are for fools: do whatever works—don't just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. 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.

| back of napkin math: Guesstimation Lawrence Weinstein, John Adam, 2009-02-09 Guesstimation is a book that unlocks the power of approximation--it's popular mathematics rounded to the nearest power of ten! The ability to estimate is an important skill in daily life. More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic. Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom. |

Physicists use “back-of-the-envelope” estimates to check whether or not an idea could possibly be right. In many cases, the approximate solution is all that is needed. This compilation of 101 examples of back-of-the-envelope calculations celebrates a quantitative approach to solving physics problems. Drawing on a lifetime of physics research and nearly three decades as the editor of The Physics Teacher, Clifford Swartz—a winner of two awards from the American Association of Physics Teachers—provides simple, approximate solutions to physics problems that span a broad range of topics. What note do you get when you blow across the top of a Coke bottle? Could you lose weight on a diet of ice cubes? How can a fakir lie on a bed of nails without getting hurt? Does draining water in the northern hemisphere really swirl in a different direction than its counterpart below the equator? In each case, only a few lines of arithmetic and a few natural constants solve a problem to within a few percent. Covering such subjects as astronomy, magnetism, optics, sound, heat, mechanics, waves, and electricity, this book provides a rich source of material for teachers and anyone interested in the physics of everyday life. “This is a book that will help make the study of physics fun and relevant.” —Mark P. Silverman, author of Waves and Grains: Reflections on Light and Learning |
| back of napkin math: The Art of Insight in Science and Engineering Sanjoy Mahajan, 2014-11-07 Tools to make hard problems easier to solve. In this book, Sanjoy Mahajan shows us that the way to master complexity is through insight rather than precision. Precision can overwhelm us with information, whereas insight connects seemingly disparate pieces of information into a simple picture. Unlike computers, humans depend on insight. Based on the author's fifteen years of teaching at MIT, Cambridge University, and Olin College, The Art of Insight in Science and Engineering shows us how to build insight and find understanding, giving readers tools to help them solve any problem in science and engineering. To master complexity, we can organize it or discard it. The Art of Insight in Science and Engineering first teaches the tools for organizing complexity, then distinguishes the two paths for discarding complexity: with and without loss of information. Questions and problems throughout the text help readers master and apply these groups of tools. Armed with this three-part toolchest, and without complicated mathematics, readers can estimate the flight range of birds and planes and the strength of chemical bonds, understand the physics of pianos and xylophones, and explain why skies are blue and sunsets are red.

| back of napkin math: Succeeding Outside the Academy Joseph Fruscione, Kelly J. Baker, 2018-10-17 Not every PhD becomes a professor. Some never want to, but others discover—too late and ill-prepared to look elsewhere—that there’s precious little room in today’s ivory tower, and what’s there might not be a good fit. For those leaving academia, or wanting out, or finding themselves adrift, this book offers hope, advice, and a bracing look at how others facing the same quandary have made careers outside of the academy work. All of the authors in this volume, as well as the editors, have built successful careers beyond the groves of academia—as freelance editors and writers, consultants and lecturers, librarians, realtors, and entrepreneurs—and each has a compelling story to tell. Their accounts afford readers a firsthand view of what it takes to transition from professor to professional. They also give plenty of practical advice, along with hard-won insights into what making a move beyond the academy might entail—emotionally, intellectually, and, not least, financially. Imparting what they wish they’d known during their PhDs, these writers aim to spare those who follow in their uncertain footsteps. Together their essays point the way out of the “tenure track or bust” mindset and toward a world of different but no less rewarding possibilities. |

| back of napkin math: A Mathematical Nature Walk John Adam, 2011-09-12 How heavy is that cloud? Why can you see farther in rain than in fog? Why are the droplets on that spider web spaced apart so evenly? If you have ever asked questions like these while outdoors, and wondered how you might figure out the answers, this is a book for you. An entertaining and informative collection of fascinating puzzles from the natural world around us, A Mathematical Nature Walk will delight anyone who loves nature or math or both. John Adam presents ninety-six questions about many common natural phenomena--and a few uncommon ones--and then shows how to answer them using mostly basic mathematics. Can you weigh a pumpkin just by carefully looking at it? Why can you see farther in rain than in fog? What causes the variations in the colors of butterfly wings, bird feathers, and oil slicks? And why are large haystacks prone to spontaneous combustion? These are just a few of the questions you'll find inside. Many of the problems are illustrated with photos and drawings, and the book also has answers, a glossary of terms, and a list of some of the patterns found in nature. About a quarter of the questions can be answered with arithmetic, and many of the rest require only precalculus. But regardless of math background, readers will learn from the informal descriptions of the problems and gain a new appreciation of the beauty of nature and the mathematics that lies behind it. |

LaPlante, 2019-09-10 A NEW YORK TIMES BESTSELLER “Brilliant and enthralling.” —The Wall Street Journal A paradigm-shifting book from an acclaimed Harvard Medical School scientist and one of Time’s most influential people. It’s a seemingly undeniable truth that aging is inevitable. But what if everything we’ve been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: “Aging is a disease, and that disease is treatable.” This eye-opening and provocative work takes us to the frontlines of research that is pushing the boundaries on our perceived scientific limitations, revealing incredible breakthroughs—many from Dr. David Sinclair’s own lab at Harvard—that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it. Recent experiments in genetic reprogramming suggest that in the near future we may not just be able to feel younger, but actually become younger. Through a page-turning narrative, Dr. Sinclair invites you into the process of scientific discovery and reveals the emerging technologies and simple lifestyle changes—such as intermittent fasting, cold exposure, exercising with the right intensity, and eating less meat—that have been shown to help us live younger and healthier for longer. At once a roadmap for taking charge of our own health destiny and a bold new vision for the future of humankind, Lifespan will forever change the way we think about why we age and what we can do about it. |
| back of napkin math: Spin Doctors Nora Loreto, 2021-11-24T00:00:00Z As Canada was in the grips of the worst pandemic in a century, Canadian media struggled to tell the story. Newsrooms, already run on threadbare budgets, struggled to make broader connections that could allow their audience to better understand what was really happening, and why. Politicians and public health officials were mostly given the benefit of the doubt that what they said was true and that they acted in good faith. This book documents each month of the first year of the pandemic and examines the issues that emerged, from racialized workers to residential care to policing. It demonstrates how politicians and uncritical media shaped the popular understanding of these issues and helped to justify the maintenance of a status quo that created the worst ravages of the crisis. Spin Doctors argues alternative ways in which Canadians should understand the big themes of the crisis and create the necessary knowledge to demand large-scale change. |

Deliberate and consensual pain has been with us for millennia, encompassing everyone from Black Plague flagellants to ballerinas dancing on broken bones to competitive eaters choking down hot peppers while they cry. Masochism is a part of us. It lives inside workaholics, tattoo enthusiasts, and all manner of garden variety pain-seekers. At its core, masochism is about feeling bad, then better—a phenomenon that is long overdue for a heartfelt and hilarious investigation. And Leigh Cowart would know: they are not just a researcher and science writer—they’re an inveterate, high-sensation seeking masochist. And they have a few questions: Why do people engage in masochism? What are the benefits and the costs? And what does masochism have to say about the human experience? By participating in many of these activities themselves, and through conversations with psychologists, fellow scientists, and people who seek pain for pleasure, Cowart unveils how our minds and bodies find meaning and relief in pain—a quirk in our programming that drives discipline and innovation even as it threatens to swallow us whole. |
| back of napkin math: Simulation and Game-Based Learning in Emergency and Disaster Management Drumhiller, Nicole K., Wilkin, Terri L., Srba, Karen V., 2021-04-02 Simulation and game-based learning are essential applications in a learning environment as they provide learners an opportunity to apply the course material in real-life scenarios. Introducing real-life learning allows the learner to make critical decisions at different points within the simulation providing constructive education that leads to a cognitive understanding of the material. The use of simulations provides the learner with the ability to cognitively store and recall learning in real-life experiences. Therefore, it is crucial to not only provide course material but to have students apply what they have learned in simulations that replicate real-life scenarios. These learned skills are essential for students to be marketable and thrive in a career field where decision making, problem solving, and critical thinking are job requirements. Simulation and Game-Based Learning in Emergency and Disaster Management is a cutting-edge research book that examines the best practices and holistic development when it comes to simulation learning within emergency and disaster management as well as global security. Drawing upon the neuroscience of learning, classroom instruction can be enhanced to incorporate active-experiential learning activities that positively impact a learner with long-term information retention. Each simulation project is carried out in different environments, with different goals in mind, and developed under various constraints. For these reasons, this book will provide insight into the simulation planning and development process, provide examples of online simulations and game-based learning activities, and provide insight on simulation development and implementation that can be used across disciplines in educational and training settings. As such, it is ideal for academicians, instructional designers, curriculum designers, education professionals, researchers, and students. |

The money myths end here. We don't need to choose between creating meaningful wealth for ourselves and our families today, or supporting social movements creating a better tomorrow. We don't all need to become certified financial experts to be economically empowered and make a real difference in our communities. And we're far from powerless when it comes to changing the financial system, just because we don't happen to belong to the 1%. Quite the opposite. Financial activism is how everyday people radically reimagine money as a tool for widespread well-being, instead of a weapon of absurdly increasing inequality. It's the antidote to traditional finance that evokes confusion, trauma, and (in the best-case scenario) straight-up boredom. It's how we-the underestimated-collectively resist systems that cause harm to people and the planet for the sake of profit, reclaim wealth that's been stolen, and redesign our relationships with capital and one another, in ways big and small. Going beyond tried financial literacy, The Financial Activist Playbook offers eight accessible, actionable, choose-your-own-adventure strategies for readers to experiment with. Drawing on timely insider knowledge from the worlds of impact investing, social justice, and more, Rashid illuminates a treasure trove of stories: demonstrating how people power can flow big bucks out of extractive industries, and into the economy of care and abundance we deserve. Playbook readers will be equipped to start visualizing and influencing the unique networks of wealth all around each of us, with strategies like Shifting collective budgets and bank dollars; Flexing our role as everyday philanthropists; Leveraging the magic of community investment; And so much more. Laced with refreshing humor, empowering exercises, and a steadfast commitment to truth-telling, Rashid takes readers on an energizing ride of financial possibility and practicality that will reverberate for generations to come. |

On March 10, 2020, president Donald Trump told a nation worried about a novel coronavirus, “We’re prepared, and we’re doing a great job with it. And it will go away. Just stay calm. It will go away.” It has since been estimated that had Trump simply taken the same steps as other G7 countries, 40 percent fewer Americans would have died. And it was not just the president. His inner circle, including Mike Pence and Jared Kushner, downplayed the crisis and mishandled the response. Cabinet members such as Betsy DeVos and Mike Pompeo undermined public safety at home and abroad to advance their agendas. Senators Ron Johnson and Mitch McConnell, governors Kristi Noem and Andrew Cuomo, judges such as Wisconsin Supreme Court justice Rebecca Bradley all promulgated public policies that led to suffering and death. Meanwhile, profiteer Pfizer (and anti-government propagandists such as Grover Norquist) fed at the public trough, while the billionaire Jeff Bezos added pandemic profits to a grotesquely bloated fortune. John Nichols closes with a call for a version of the Pecora Commission, which took aim at what Franklin Delano Roosevelt called the “speculation, reckless banking, class antagonism, and profiteering” that stoked the Depression. There must be accountability. |

Lauck, Gleaves Whitney, Joseph Hogan, 2018-11 In comparison to such regions as the South, the far West, and New England, the Midwest and its culture have been neglected both by scholars and by the popular press. Historians as well as literary and art critics tend not to examine the Midwest in depth in their academic work. And in the popular imagination, the Midwest has never really ascended to the level of the proud, literary South; the cultured, democratic Northeast; or the hip, innovative West Coast. Finding a New Midwestern History revives and identifies anew the Midwest as a field of study by promoting a diversity of viewpoints and lending legitimacy to a more in-depth, rigorous scholarly assessment of a large region of the United States that has largely been overlooked by scholars. The essays discuss facets of midwestern life worth examining more deeply, including history, religion, geography, art, race, culture, and politics, and are written by well-known scholars in the field such as Michael Allen, Jon Butler, and Nicole Etcheson. |

After growing up in suburban New England, following the social norms and reluctantly falling into the average category in just about everything, Brad Herrick wasn't quite ready to take on the average adult lifestyle yet. With the light shining bright at the end of the college tunnel, Brad finds himself with the opportunity of a lifetime after he made a joke comment to his dad: a chance to hike the infamous Appalachian Trail. The conversation went something like this: Brad: I don't want to grow up yet! I'll just go and hike the Appalachian Trail! Dad: Okay. Do it. Brad: Wait, what? Follow Brad as he tries to conquer the extraordinary as he walks almost 2,200 miles from Katahdin in Maine through fourteen states to Springer Mountain in Georgia. As his average life slowly takes a back seat, it's gradually replaced with exciting, funny, and ridiculous adventures, both on and off the trail, with friends old and new. It's a trail of discovery as Brad finds perseverance, adventure, an expanded world view, a love of food and reading, the proper use of diaper rash cream, and the journey out of the average category. |

These stories span a vast cultural and geographic landscape-from Indonesia, Iran, and the Arab Middle East to North America. These granular case studies contextualize cyber Islam within broader social trends: racism and Islamophobia, gender dynamics, celebrity culture, identity politics, and the shifting terrain of contemporary religious piety and practice. The book's authors examine an expansive range of digital multimedia technologies as primary “texts.” These include websites, podcasts, blogs, Twitter, Facebook, Instagram, YouTube channels, online magazines and discussion forums, and religious apps. The contributors also draw on a range of methodological and theoretical models from multiple academic disciplines, including communication and media studies, anthropology, history, global studies, religious studies, and Islamic studies. |

| back of napkin math: Life in the Middle Neilan S. Chaturvedi, 2021-09-28 A long-held belief of political scientists is that moderate voices in the Senate act as power brokers between the ideological poles, yet year after year we see partisan gridlock in Congress. Some even argue that the shrinking number of moderates only increases their political influence. In Life in the Middle, Neilan S. Chaturvedi argues that the belief in the powerful, pivotal moderate neglects their electoral circumstances and overestimates their legislative power. In other words, not all Senators are elected under equal circumstances. Chaturvedi posits that, unlike their ideological counterparts who are elected from states that share an ideological identity, moderates are elected from one of two constituencies: states that have a partisan lean to one party but have enough swing voters to vote in a moderate from the opposite party, or states that are nearly evenly divided in terms of partisanship. Using unique interview data with legislative directors, retired United States Senators, and data compiled from the Congressional Record, Chaturvedi shows that, because of their precarious electoral circumstances, moderate senators must avoid active participation on bills and pushing controversial legislation. Lawmaking is much more variable and less moderating than previous theories assumed, as the process relies less on the work of moderates and more on party leaders. The book also demonstrates that mainstream concerns about polarization and its negative effects of increased gridlock and ideological legislation are true. |
| back of napkin math: The Martian: Classroom Edition Andy Weir, 2016-05-03 In the Classroom Edition of The Martian: Classroom-appropriate language Discussion questions and activities Q&A with Andy Weir Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive—and even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plain-old human error are much more likely to kill him first. But Mark isn't ready to give up yet. Drawing on his ingenuity, his engineering skills—and a relentless, dogged refusal to quit—he steadfastly confronts one seemingly insurmountable obstacle after the next. Will his resourcefulness be enough to overcome the impossible odds against him? |
| back of napkin math: Heard It in a Love Song Tracey Garvis Graves, 2021-11-09 From Tracey Garvis Graves, the bestselling author of The Girl He Used to Know comes a love song of a story about starting over and second chances in Heard It in a Love Song. Love doesn’t always wait until you’re ready. Layla Hilding is thirty-five and recently divorced. Struggling to break free from the past—her glory days as the lead singer in a band and a ten-year marriage to a man who never put her first—Layla’s newly found independence feels a lot like loneliness. Then there's Josh, the single dad whose daughter attends the elementary school where Layla teaches music. Recently separated, he's still processing the end of his twenty-year marriage to his high school sweetheart. He chats with Layla every morning at school and finds himself thinking about her more and more. Equally cautious and confused about dating in a world that favors apps over meeting organically, Layla and Josh decide to be friends with the potential for something more. Sounds sensible and way too simple—but when two people are on the rebound, is it heartbreak or happiness that’s a love song away? |
| back of napkin math: Almost Dysfunctional Larry Hubbell, 2002-02 Walter Stanley, a middle-aged, mildly obsessive and slightly above average American political science professor, thinks he may have made a mistake. Why did he choose Russia as the site for his sabbatical? He's tired of the drunken camaraderie; he finds the crowded buses a Hobbesian world writ small; and he frequently becomes irate stepping in dog feces in the halls of his apartment. Away from his wife and family, he meets Lientjies Steenkamp, a beautiful, young South African Communist, who he becomes infatuated with upon their first meeting. Can a slightly burned out, tenured college professor find happiness in a dreary society with a woman fifteen years his junior? |
| back of napkin math: Foxocracy Tobin Smith, 2019-10-29 From a 14-year Fox News contributor, guest anchor, and two-time New York Times bestselling author comes an unprecedented insider's account of the Fox News playbook––the production secrets and manipulation strategies Fox News uses to influence viewers, divide families, weaponize the daily discourse of news and public opinion, and addict a core audience on right-wing rage and fear. Fox News did not start America's culture war––but they did have the manipulative and destructive genius to exploit it for billions of dollars. For the first time, a Fox News veteran exposes and diagrams the toxic strategies and tactics within the Fox News playbook that liberal and progressive candidates will be fighting against in 2020 and beyond. It is the very same playbook that Fox News used to move twelve percent of Independents to vote for Donald Trump in 2016 to produce Republican wins in the previous Democrat strongholds of Ohio, Wisconsin, and Pennsylvania. Author Tobin Smith takes readers behind the scenes of the actual production of the fair and balanced opinion panel segments that feed a ravenous audience. How are these productions rigged so that right-wing pundits always win? What techniques does Fox News use in manipulating its viewers' tribal instincts: to addict them; to activate a hatred toward partisan enemies; and to hook them on ego-gratifying feelings of intellectual and cultural superiority? Foxocracy is filled with never-revealed conversations with Fox News executives––including the late Roger Ailes––and opinion programming producers. It breaks down the real and often heartbreaking collateral damage among friends and family caused by the waging of an endless culture war. And it brings incendiary proof from an insider and on-air talent of Fox News's predatory audience manipulation psychology and production tactics. And perhaps even more frightening, this book reveals how that playbook is now being insidiously upgraded for maximum effect––white tribal-identity activation––on all forms of social media and means of content delivery. |
| back of napkin math: The Constitution of Algorithms Florian Jaton, 2021-04-27 A laboratory study that investigates how algorithms come into existence. Algorithms--often associated with the terms big data, machine learning, or artificial intelligence--underlie the technologies we use every day, and disputes over the consequences, actual or potential, of new algorithms arise regularly. In this book, Florian Jaton offers a new way to study computerized methods, providing an account of where algorithms come from and how they are constituted, investigating the practical activities by which algorithms are progressively assembled rather than what they may suggest or require once they are assembled. |
