When Form Becomes Substance: Power of Gestures, Diagrammatical Intuition and Phenomenology of Space
by Luciano Boi Carlos LoboThis interdisciplinary volume collects contributions from experts in their respective fields with as common theme diagrams.Diagrams play a fundamental role in the mathematical visualization and philosophical analysis of forms in space. Some of the most interesting and profound recent developments in contemporary sciences, whether in topology, geometry, dynamic systems theory, quantum field theory or string theory, have been made possible by the introduction of new types of diagrams, which, in addition to their essential role in the discovery of new classes of spaces and phenomena, have contributed to enriching and clarifying the meaning of the operations, structures and properties that are at the heart of these spaces and phenomena.The volume gives a closer look at the scope and the nature of diagrams as constituents of mathematical and physical thought, their function in contemporary artistic work, and appraise, in particular, the actual importance of the diagrams of knots, of braids, of fields, of interaction, of strings in topology and geometry, in quantum physics and in cosmology, but also in theory of perception, in plastic arts and in philosophy. The editors carefully curated this volume to be an inspiration to students and researchers in philosophy, phenomenology, mathematics and the sciences, as well as artists, musicians and the general interested audience.

When Least Is Best
by Paul J. NahinWhat is the best way to photograph a speeding bullet? Why does light move through glass in the least amount of time possible? How can lost hikers find their way out of a forest? What will rainbows look like in the future? Why do soap bubbles have a shape that gives them the least area? By combining the mathematical history of extrema with contemporary examples, Paul J. Nahin answers these intriguing questions and more in this engaging and witty volume. He shows how life often works at the extremes--with values becoming as small (or as large) as possible--and how mathematicians over the centuries have struggled to calculate these problems of minima and maxima. From medieval writings to the development of modern calculus to the current field of optimization, Nahin tells the story of Dido's problem, Fermat and Descartes, Torricelli, Bishop Berkeley, Goldschmidt, and more. Along the way, he explores how to build the shortest bridge possible between two towns, how to shop for garbage bags, how to vary speed during a race, and how to make the perfect basketball shot. Written in a conversational tone and requiring only an early undergraduate level of mathematical knowledge, When Least Is Best is full of fascinating examples and ready-to-try-at-home experiments. This is the first book on optimization written for a wide audience, and math enthusiasts of all backgrounds will delight in its lively topics.

Where Did You Get This Number?: A Pollster's Guide to Making Sense of the World
by Anthony SalvantoCBS News’ Elections and Surveys Director Anthony Salvanto takes you behind the scenes of polling to show you how to think about who we are and where we’re headed as a nation.As Elections and Surveys Director for CBS News, it’s Anthony Salvanto’s job to understand you—what you think and how you vote. He’s the person behind so many of the poll numbers you see today, making the winner calls on election nights and surveying thousands of Americans. In Where Did You Get This Number? A Pollster’s Guide to Making Sense of the World, Salvanto takes readers on a fast-paced, eye-opening tour through the world of polling and elections and what they really show about America today, beyond the who's-up-who’s-down headlines and horse races. Salvanto is just the person to bring much-needed clarity in a time when divisions seem to run so deep. The language of polling may be numbers, but the stories it tells are about people. In this engaging insider’s account, Salvanto demystifies jargon with plain language and answers readers’ biggest questions about polling and pollsters. How can they talk to 1,000 people and know the country? How do they know the winner so fast? How do they decide what questions to ask? Why didn't they call you? Salvanto offers data-driven perspective on how Americans see the biggest issues of our time, from the surprising 2016 election, to the shocks of the financial crisis, the response to terrorism and the backlash against big money. He doesn’t shy away from pointing out what’s worked and what hasn’t. Salvanto takes readers inside the CBS newsroom on Election Night 2016 and makes readers rethink conventional wisdom and punditry just in time for the 2018 midterms. He shows who really decides elections and why you should think about a poll differently from the forecasts popularized by Nate Silver and others. Where Did You Get This Number? is an essential resource for anyone interested in politics—and how to better measure and understand patterns of human behavior. For any American who wants to get a better read on what America is thinking, this book shows you how to make sense of it all.
Where Do Numbers Come From?
by T. W. KörnerWhy do we need the real numbers? How should we construct them? These questions arose in the nineteenth century, along with the ideas and techniques needed to address them. Nowadays it is commonplace for apprentice mathematicians to hear 'we shall assume the standard properties of the real numbers' as part of their training. But exactly what are those properties? And why can we assume them? This book is clearly and entertainingly written for those students, with historical asides and exercises to foster understanding. Starting with the natural (counting) numbers and then looking at the rational numbers (fractions) and negative numbers, the author builds to a careful construction of the real numbers followed by the complex numbers, leaving the reader fully equipped with all the number systems required by modern mathematical analysis. Additional chapters on polynomials and quarternions provide further context for any reader wanting to delve deeper.
Where is the Gödel-point hiding: Gentzen's Consistency Proof of 1936 and His Representation of Constructive Ordinals
by Anna HorskáThis book explains the first published consistency proof of PA. It contains the original Gentzen's proof, but it uses modern terminology and examples to illustrate the essential notions. The author comments on Gentzen's steps which are supplemented with exact calculations and parts of formal derivations. A notable aspect of the proof is the representation of ordinal numbers that was developed by Gentzen. This representation is analysed and connection to set-theoretical representation is found, namely an algorithm for translating Gentzen's notation into Cantor normal form. The topic should interest researchers and students who work on proof theory, history of proof theory or Hilbert's program and who do not mind reading mathematical texts.
Where the Hood At?: Fifty Years of Change in Black Neighborhoods
by Michael C. LensSubstantial gaps exist between Black Americans and other racial and ethnic groups in the U.S., most glaringly Whites, across virtually all quality-of-life indicators. Despite strong evidence that neighborhood residence affects life outcomes, we lack a comprehensive picture of Black neighborhood conditions and how they have changed over time. In Where the Hood At? urban planning and public policy scholar Michael C. Lens examines the characteristics and trajectories of Black neighborhoods across the U.S. over the fifty years since the Fair Housing Act. Hip hop music was born out of Black neighborhoods in the 1970s and has evolved alongside them. In Where the Hood At? Lens uses rap’s growth and influence across the country to frame discussions about the development and conditions of Black neighborhoods. Lens finds that social and economic improvement in Black neighborhoods since the 1970s has been slow. However, how well Black neighborhoods are doing varies substantially by region. Overall, Black neighborhoods in the South are doing well and growing quickly. Washington D.C. and Atlanta, in particular, stand out as centers of Black affluence. Black neighborhoods in the Midwest and the Rust Belt, on the other hand, are particularly disadvantaged. The welfare of Black neighborhoods is related not only to factors within neighborhoods, such as the unemployment rate, but also to characteristics of the larger metropolitan area, such as overall income inequality. Lens finds that while gentrification is increasingly prevalent, it is growing slowly, and is not as pressing an issue as public discourse would make it seem. Instead, concentrated disadvantage is by far the most common and pressing problem in Black neighborhoods. Lens argues that Black neighborhoods represent urban America’s greatest policy failures, and that recent housing policies have only had mild success. He provides several suggestions for policies with the goal of uplifting Black neighborhoods. One radical proposal is enacting policies and programs, such as tax breaks for entrepreneurs or other small business owners, that would encourage Black Americans to move back to the South. Black Americans migrating South would have a better chance at moving to an advantaged Black neighborhood as improving neighborhood location is higher when moving across regions. It would also help Black Americans expand their political and economic power. He also suggests a regional focus for economic development policies, particularly in the Midwest where Black neighborhoods are struggling the most. One way to boost economic development would be to move federal agencies to the area. He also calls for building more affordable housing in Black suburbs. Black poverty is lower in suburbs than in central cities, so increasing housing in Black suburbs would allow Black households to relocate to more advantaged neighborhoods, which research has shown leads to improved life outcomes. Where the Hood At? is a remarkable and comprehensive account of Black neighborhoods that helps us to better understand the places and conditions that allow them flourish or impedes their advancement.
Where's the Wonder in Elementary Math?: Encouraging Mathematical Reasoning in the Classroom
by Judith McVarishThis book argues that even in today's high-stakes testing environment, 'teaching to the test' need not be teachers’ only focus as they introduce young children to mathematics. Judith McVarish demonstrates how building a community of learners and using problem solving to engage students can help teachers encourage students’ disposition to creative thinking and reasoning—skills that can otherwise become lost due to the pressure of the many other expectations placed upon both teachers and students. This book offers strategies for infusing mathematics learning and reasoning into elementary school classrooms while meeting curriculum and testing mandates. The teacher researcher component of each chapter provides a vehicle for teachers to bring their own expertise and questions back into the teaching and learning equation.

Who Gets What—and Why: The New Economics Of Matchmaking And Market Design
by Alvin E. Roth&“In his fluent and accessible book, Mr. Roth vividly describes the successes of market design.&” — Economist.com? &“In this fascinating, often surprising book, Alvin Roth guides us through the jungles of modern life, pointing to the many markets that are hidden in plain view all around us.&” — Dan Ariely, author of Predictably Irrational and The (Honest) Truth About Dishonesty Most of the study of economics deals with commodity markets, where the price of a good connects sellers and buyers. But what about other kinds of &“goods,&” like a spot in the Yale freshman class or a position at Google? If you&’ve ever sought a job or hired someone, applied to college or guided your child into a good kindergarten, asked someone out on a date or been asked out, you&’ve participated in a kind of market. This is the territory of matching markets, where &“sellers&” and &“buyers&” must choose each other, and price isn&’t the only factor determining who gets what. In Who Gets What—and Why, Nobel laureate Alvin E. Roth reveals the matching markets hidden around us and shows us how to recognize a good match and make smarter, more confident decisions. &“Mr. Roth&’s work has been to discover the most efficient and equitable methods of matching, and implement them in the world. He writes with verve and style . . . Who Gets What—and Why is a pleasure to read.&” — Wall Street Journal &“A book filled with wit, charm, common sense, and uncommon wisdom.&” — Paul Milgrom, professor of economics, Stanford University and Stanford Business School

Who Will Feed China?: Wake-Up Call for a Small Planet (Routledge Revivals)
by Lester BrownOriginally published in 1995, but with enduring relevance in a time of global population growth and food insecurity, when it was first published, this book attracted much global attention, and criticism from Beijing. It argued that even as water becomes scarcer in a land where 80% of the grain crop is irrigated, as per-acre yield gains are erased by the loss of agricultural land to industrialization, and as food production stagnates, China still increases its population by the equivalent of a new Beijing each year. This book predicts that in an integrated world economy, China’s rising food prices will become the world’s rising food prices. China’s land scarcity will come everyone’s land scarcity and water scarcity in China will affect the entire world. China’s dependence on massive imports, like the collapse of the world’s fisheries, will be a wake-up call that we are colliding with the earth’s capacity to feed us. Over time, Janet Larsen argued, China’s leaders came to ‘acknowledge how Who Will Feed China? changed their thinking..’ As China’s wealth increases, so do the dietary demands of its population. The increasing middle classes demand more grain-intensive meat and farmed fish. The issue of who will feed China has not gone away.
Who Wrote Citizen Kane?: Statistical Analysis of Disputed Co-Authorship (Quantitative Methods in the Humanities and Social Sciences)
by Warren BucklandThis book offers a solution to one of film history’s major controversies: the long-running dispute over Orson Welles’ and Herman J. Mankiewicz’s contributions to the Citizen Kane screenplay. It establishes the vital importance of computing and statistics to solving previously intractable puzzles in the arts and humanities. Citizen Kane (1941) is one of the most acclaimed films in the history of cinema. For 50 years it topped the Sight & Sound film critics’ poll. Orson Welles directed the film and is credited with co-writing the screenplay with Herman J. Mankiewicz. But the co-writer credit generates furious disputes between those who argue Mankiewicz is the sole author of Citizen Kane and those who claim that Welles collaborated fully with its writing. The author employs computing and statistics to answer two questions: What are the distinguishing features of Welles’ and of Mankiewicz’s writing? And What did each contribute to the writing of the Citizen Kane screenplay? To answer these questions, the author bypasses opinions and impressions, and instead subjects the language of the Citizen Kane screenplay to a ‘forensic’ examination. Employing linguistics, basic statistical tests, plus computer technology and software, the author identifies the stylistic signature of each author – the combination of consistent and regular linguistic habits that make each author’s writing distinctive. This book replaces impressionistic discussions of Mankiewicz’s and Welles’ contributions to the Citizen Kane screenplay with a rigorous, experiment-driven statistical analysis. Earlier statistical studies of authorship have discovered that small, unassuming language features (such as punctuation, pronouns, and prepositions) in statistically significant quantities, constitute a screenwriter’s distinctive writing habits. Only with the extensive experimentation carried out in this volume, did the author decide Mankiewicz’s and Welles’ specific habits and their contributions to Citizen Kane.
The Whole Truth About Whole Numbers
by Sylvia Forman Agnes M. RashThe Whole Truth About Whole Numbers is an introduction to the field of Number Theory for students in non-math and non-science majors who have studied at least two years of high school algebra. Rather than giving brief introductions to a wide variety of topics, this book provides an in-depth introduction to the field of Number Theory. The topics covered are many of those included in an introductory Number Theory course for mathematics majors, but the presentation is carefully tailored to meet the needs of elementary education, liberal arts, and other non-mathematical majors. The text covers logic and proofs, as well as major concepts in Number Theory, and contains an abundance of worked examples and exercises to both clearly illustrate concepts and evaluate the students' mastery of the material.

Why Does Math Work … If It's Not Real?: Episodes in Unreasonable Effectiveness
by Dragan RadulovićAccording to G. H. Hardy, the 'real' mathematics of the greats like Fermat and Euler is 'useless,' and thus the work of mathematicians should not be judged on its applicability to real-world problems. Yet, mysteriously, much of mathematics used in modern science and technology was derived from this 'useless' mathematics. Mobile phone technology is based on trig functions, which were invented centuries ago. Newton observed that the Earth's orbit is an ellipse, a curve discovered by ancient Greeks in their futile attempt to double the cube. It is like some magic hand had guided the ancient mathematicians so their formulas were perfectly fitted for the sophisticated technology of today. Using anecdotes and witty storytelling, this book explores that mystery. Through a series of fascinating stories of mathematical effectiveness, including Planck's discovery of quanta, mathematically curious readers will get a sense of how mathematicians develop their concepts.
