Bernoulli's Fallacy: Statistical Illogic and the Crisis of Modern Science


Aubrey Clayton - 2021
    This fault is not a minor academic quibble: it underlies a reproducibility crisis now threatening entire disciplines. In an increasingly statistics-reliant society, this same deeply rooted error shapes decisions in medicine, law, and public policy with profound consequences. The foundation of the problem is a misunderstanding of probability and its role in making inferences from observations.Aubrey Clayton traces the history of how statistics went astray, beginning with the groundbreaking work of the seventeenth-century mathematician Jacob Bernoulli and winding through gambling, astronomy, and genetics. Clayton recounts the feuds among rival schools of statistics, exploring the surprisingly human problems that gave rise to the discipline and the all-too-human shortcomings that derailed it. He highlights how influential nineteenth- and twentieth-century figures developed a statistical methodology they claimed was purely objective in order to silence critics of their political agendas, including eugenics.Clayton provides a clear account of the mathematics and logic of probability, conveying complex concepts accessibly for readers interested in the statistical methods that frame our understanding of the world. He contends that we need to take a Bayesian approach--that is, to incorporate prior knowledge when reasoning with incomplete information--in order to resolve the crisis. Ranging across math, philosophy, and culture, Bernoulli's Fallacy explains why something has gone wrong with how we use data--and how to fix it.

Journey to the Edge of Reason: The Life of Kurt Gödel


Stephen Budiansky - 2021
    Yet unlike Einstein, with whom he formed a warm and abiding friendship, Gödel has long escaped all but the most casual scrutiny of his life.Stephen Budiansky’s Journey to the Edge of Reason is the first biography to fully draw upon Gödel’s voluminous letters and writings—including a never-before-transcribed shorthand diary of his most intimate thoughts—to explore Gödel’s profound intellectual friendships, his moving relationship with his mother, his troubled yet devoted marriage, and the debilitating bouts of paranoia that ultimately took his life. It also offers an intimate portrait of the scientific and intellectual circles in prewar Vienna, a haunting account of Gödel’s and Jewish intellectuals’ flight from Austria and Germany at the start of the Second World War, and a vivid re-creation of the early days of Princeton’s Institute for Advanced Study, where Gödel and Einstein both worked.Eloquent and insightful, Journey to the Edge of Reason is a fully realized portrait of the odd, brilliant, and tormented man who has been called the greatest logician since Aristotle, and illuminates the far-reaching implications of Gödel’s revolutionary ideas for philosophy, mathematics, artificial intelligence, and man’s place in the cosmos.

Math Without Numbers


Milo Beckman - 2021
    This book upends the conventional approach to math, inviting you to think creatively about shape and dimension, the infinite and infinitesimal, symmetries, proofs, and how these concepts all fit together. What awaits readers is a freewheeling tour of the inimitable joys and unsolved mysteries of this curiously powerful subject.Like the classic math allegory Flatland, first published over a century ago, or Douglas Hofstadter's Godel, Escher, Bach forty years ago, there has never been a math book quite like Math Without Numbers. So many popularizations of math have dwelt on numbers like pi or zero or infinity. This book goes well beyond to questions such as: How many shapes are there? Is anything bigger than infinity? And is math even true? Milo Beckman shows why math is mostly just pattern recognition and how it keeps on surprising us with unexpected, useful connections to the real world.The ambitions of this book take a special kind of author. An inventive, original thinker pursuing his calling with jubilant passion. A prodigy. Milo Beckman completed the graduate-level course sequence in mathematics at age sixteen, when he was a sophomore at Harvard; while writing this book, he was studying the philosophical foundations of physics at Columbia under Brian Greene, among others.

Number Theory


Andrej Dujella - 2021
    Thus it has often been considered as the "purest" branch of mathematics in the sense that it was the furthest from any specific application. However, nowadays number theory is considered to be one of the most important branches of mathematics for application in cryptography. This book is based on teaching materials from an undergraduate course Elementary Number Theory and graduate courses Diophantine equations and Diophantine Approximations and Application. The book also provides an insight into subjects that are at the centre of research interest of the author of the book as well as other members of the Croatian number theory research group. This book is primarily intended for undergraduate students who attend courses in number theory and its application. Also, it can be useful for advanced high school students who are preparing for competition in mathematics in which at all levels, from the school level competition to the international competition number theory has a significant role. In addition, it is intended for graduate students and researchers in the fields of number theory, algebra and cryptography.

Winning the Right Game: Strategy in the Age of Ecosystems


Ron Adner - 2021
    Are you prepared? Rivalry is shifting from well-defined industries to broader ecosystems: automobiles to mobility platforms; banking to fintech; television broadcasting to video streaming. Your competitors are coming from new directions and pursuing different goals from those of your familiar rivals. In this world, succeeding with the old rules can mean losing the new game. Winning the Right Game introduces the concepts, tools, and frameworks necessary to confront the threat of ecosystem disruption and to develop the strategies that will let your organization play ecosystem offense.To succeed in this world, you need to change your perspective on competition, growth, and leadership. In this book, strategy expert Ron Adner offers a new way of thinking, illustrating breakthrough ideas with compelling cases. How did a strategy of ecosystem defense save Wayfair and Spotify from being crushed by giants Amazon and Apple? How did Oprah Winfrey redraw industry boundaries to transition from television host to multimedia mogul? How did a shift to an alignment mindset enable Microsoft's cloud-based revival? Each was rooted in a new approach to competitors, partners, and timing that you can apply to your own organization. For today's leaders the difference between success and failure is no longer simply winning, but rather being sure that you are winning the right game.

Conversations on Quantum Gravity


J�come (Jay) Armas - 2021
    This book addresses the question: how far are we from such discovery? Over the last few decades, multiple roads to finding a quantum theory of gravity have been proposed but no obvious description of nature has emerged in this domain. What is to be made of this situation? This volume probes the state-of-the art in this daunting quest of theoretical physics by collecting critical interviews with nearly forty leading theorists in this field. These broad-ranging conversations give important insights and candid opinions on the various approaches to quantum gravity, including string theory, loop quantum gravity, causal set theory and asymptotic safety. This unique, readable overview provides a gateway into cutting edge research for students and others who wish to engage with the open problem of quantum gravity.

Algebra: Notes from the Underground


Paolo Aluffi - 2021
    The text emphasizes a modern perspective on the subject, with gentle mentions of the unifying categorical principles underlying the various constructions and the role of universal properties. A key feature is the treatment of modules, including a proof of the classification theorem for finitely generated modules over Euclidean domains. Noetherian modules and some of the language of exact complexes are introduced. In addition, standard topics - such as the Chinese Remainder Theorem, the Gauss Lemma, the Sylow Theorems, simplicity of alternating groups, standard results on field extensions, and the Fundamental Theorem of Galois Theory - are all treated in detail. Students will appreciate the text's conversational style, 400+ exercises, an appendix with complete solutions to around 150 of the main text problems, and an appendix with general background on basic logic and na�ve set theory.

Proofs: A Long-Form Mathematics Textbook


Jay Cummings - 2021
    Rather than the typical definition-theorem-proof-repeat style, this text includes much more commentary, motivation and explanation. The proofs are not terse, and aim for understanding over economy. Furthermore, dozens of proofs are preceded by "scratch work" or a proof sketch to give students a big-picture view and an explanation of how they would come up with it on their own. This book covers intuitive proofs, direct proofs, sets, induction, logic, the contrapositive, contradiction, functions and relations. The text aims to make the ideas visible, and contains over 200 illustrations. The writing is relaxed and conversational, and includes periodic attempts at humor. This text is also an introduction to higher mathematics. This is done in-part through the chosen examples and theorems. Furthermore, following every chapter is an introduction to an area of math. These include Ramsey theory, number theory, topology, sequences, real analysis, big data, game theory, cardinality and group theory. After every chapter are "pro-tips," which are short thoughts on things I wish I had known when I took my intro-to-proofs class. They include finer comments on the material, study tips, historical notes, comments on mathematical culture, and more. Also, after each chapter's exercises is an introduction to an unsolved problem in mathematics. In the first appendix we discuss some further proof methods, the second appendix is a collection of particularly beautiful proofs, and the third is some writing advice. ~Jay Cummings

101 Involved Algebra Problems with Answers


Chris McMullen - 2021
    This book includes separate sections of answers, hints, and full solutions. Prerequisites include multiplying expressions with square roots, systems of equations, the quadratic formula, the equation for a straight line, power rules, factoring, and other standard algebra techniques. A variety of problems are included, such as: * systems of equations (many are nonstandard, including a quadratic term or a reciprocal, for example) * simplifying expressions or solving equations that feature square roots * applying algebra to derive equations * variables in the denominator * rules for exponents * inequalities * the equation for a straight line * multiplying, distributing, or factoring expressions * applications of algebra (such as in classic physics problems) * transformations of variables * exposure to techniques such as completing the square, partial fractions, or separation of variables * cross multiplying * ratios * rationalizing the denominator and multiplying by the conjugate. This book is NOT indented to “teach” algebra (though the solutions may be instructive), but is designed to offer practice with a variety of algebra skills (which most students could benefit from) for students who are familiar with the skills listed. The author, Chris McMullen, PhD, has over twenty years of experience teaching math skills to physics students. He prepared this workbook of the Improve Your Math Fluency series to share his strategies for solving algebra problems.

Enchantment of the Virtual: Mathematics, Physics, Philosophy


Gilles ChâteletDan Mellamphy - 2021
    Châtelet was not only a philosopher, political theorist, theorist of individuation and of the magnification of human freedoms, but also a talented mathematician and an original theorist of the virtual, the diagram, and the gesture.With their characteristic ebullience and speculative agility in transporting concepts between different fields, Châtelet's polymath interrogations were an acknowledged inspiration to his fellow philosophers, including Gilles Deleuze and Alain Badiou.In the essays collected in this volume, Châtelet explores the articulation between mathematics and physical reality, algebra and geometry, romanticism and science, finite beings and the infinite manifestations of nature, and gesture and abstraction. The book also offers interviews with Châtelet and review articles in which he reckons with contemporaries including Badiou, Deleuze, Roger Penrose, and René Thom.The extensive introduction by Châtelet's former colleague Charles Alunni outlines the life and career of this “last romantic philosopher” and the continuing importance of his work for our understanding of the relationships between the mathematical and the physical, the abstract and the concrete, and scientific thinking and the politics of liberation.

The Effect: An Introduction to Research Design and Causality


Nick Huntington-Klein - 2021
    It is separated into two halves, each with different approaches to that subject. The first half goes through the concepts of causality, with very little in the way of estimation. It introduces the concept of identification thoroughly and clearly and discusses it as a process of trying to isolate variation that has a causal interpretation. Subjects include a heavy emphasis on data-generating processes and causal diagrams.Concepts are demonstrated with a heavy emphasis on graphical intuition and the question of what we do to data. When we “add a control variable” what does that actually do?Key Features:• Extensive code examples in R, Stata, and Python• Chapters on overlooked topics in econometrics classes: heterogeneous treatment effects, simulation and power analysis, new cutting-edge methods, and uncomfortable ignored assumptions• An easy-to-read conversational tone• Up-to-date coverage of methods with fast-moving literature like difference-in-differences
