Par Jason Roberts. 2024
From the bestselling author of A Sense of the World comes this dramatic, globe-spanning and meticulously-researched story of two scientific…
rivals and their race to survey all life on Earth.In the 18th century, two men dedicated their lives to the same daunting task: identifying and describing all life on Earth. Their approaches could not have been more different. Carl Linnaeus, a pious Swedish doctor with a huckster's flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France's royal garden, viewed life as a dynamic swirl of complexities. Both began believing their work to be difficult, but not impossible—how could the planet possibly hold more than a few thousand species? Stunned by life's diversity, both fell far short of their goal. But in the process they articulated starkly divergent views on nature, on humanity's role in shaping the fate of our planet and on humanity itself. The rivalry between these two unique, driven individuals created reverberations that still echo today. Linnaeus, with the help of acolyte explorers he called "apostles" (only half of whom returned alive), gave the world such concepts as mammal, primate and homo sapiens—but he also denied species change and promulgated racist pseudo-science. Buffon coined the term reproduction, formulated early prototypes of evolution and genetics, and argued passionately against prejudice. It was a clash that, during their lifetimes, Buffon seemed to be winning. But their posthumous fates would take a very different turn.With elegant, propulsive prose grounded in more than a decade of research, featuring appearances by Voltaire, Benjamin Franklin and Charles Darwin, bestselling author Jason Roberts tells an unforgettable true-life tale of intertwined lives and enduring legacies, tracing an arc of insight and discovery that extends across three centuries into the present day.A surprising, groundbreaking, and fiercely entertaining medical history that is both a collective narrative of women's bodies and a call…
to action for a new conversation around women's health. For as long as medicine has been a practice, women's bodies have been treated like objects to be practiced on: examined and ignored, idealized and sexualized, shamed, subjugated, mutilated, and dismissed. The history of women's healthcare is a story in which women themselves have too often been voiceless—a narrative instead written from the perspective of men who styled themselves as authorities on the female of the species, yet uninformed by women's own voices, thoughts, fears, pain and experiences. The result is a cultural and societal legacy that continues to shape the (mis)treatment and care of women. While the modern age has seen significant advancements in the medical field, the notion that female bodies are flawed inversions of the male ideal lingers on—as do the pervasive societal stigmas and lingering ignorance that shape women's health and relationships with their own bodies. Memorial Sloan Kettering oncologist and medical historian Dr. Elizabeth Comen draws back the curtain on the collective medical history of women to reintroduce us to our whole bodies—how they work, the actual doctors and patients whose perspectives and experiences laid the foundation for today's medical thought, and the many oversights that still remain unaddressed. With a physician's knowledge and empathy, Dr. Comen follows the road map of the eleven organ systems to share unique and untold stories, drawing upon medical texts and journals, interviews with expert physicians, as well as her own experience treating thousands of women. Empowering women to better understand ourselves and advocate for care that prioritizes healthy and joyful lives— for us and generations to come—All in Her Head is written with humor, wisdom, and deep scientific and cultural insight. Eye-opening, sometimes enraging, yet always captivating, this shared memoir of women's medical history is an essential contribution to a holistic understanding and much-needed reclaiming of women's history and bodiesThe bodies keep coming: Dispatches from a black trauma surgeon on racism, violence, and how we heal
Par Brian H Williams. 2023
Trauma surgeon Dr. Brian H. Williams has seen it all—gunshot wounds, stabbings, traumatic brain injuries—and ushers us into the trauma…
bay, where the wounds of a national emergency amass. As a Harvard-trained physician, he learned to keep his head down and his scalpel ready. As a Black man, he learned to swallow rage when patients told him to take out the trash. Just days after the tragic police shootings of two Black men, he tried to save the lives of officers shot in the deadliest incident for US law enforcement since 9/11. Thrust into the spotlight in a nation that loves feel-good stories more than hard truths, he came to rethink everything he thought he knew about medicine, injustice, and what true healing looks like. Now, in raw, intimate detail, he narrates not only the events of that night, but the grief and anger of a Black doctor on the front lines of trauma care. Working in the physician-writer tradition of Gawande and Tweedy, he diagnoses the roots of the violence that plagues us. He draws a through line between white supremacy, gun violence, and the bodies he tries to revive, training his surgeon's gaze on the structural ills manifesting themselves in his patients' bodies. What if racism is a feature of our healthcare system, not a bug? What if profiting from racial inequality is exactly what it's designed to do? Black and brown bodies will continue to be wracked by all types of violence, Williams argues, until we transform policy and law with compassion and careHacker culture can be esoteric, but this entertaining reference is here to help.

Par Amy N. Langville, Carl D. Meyer. 2006
Why doesn't your home page appear on the first page of search results, even when you query your own name?…
How do other web pages always appear at the top? What creates these powerful rankings? And how? The first book ever about the science of web page rankings, Google's PageRank and Beyond supplies the answers to these and other questions and more. The book serves two very different audiences: the curious science reader and the technical computational reader. The chapters build in mathematical sophistication, so that the first five are accessible to the general academic reader. While other chapters are much more mathematical in nature, each one contains something for both audiences. For example, the authors include entertaining asides such as how search engines make money and how the Great Firewall of China influences research. The book includes an extensive background chapter designed to help readers learn more about the mathematics of search engines, and it contains several MATLAB codes and links to sample web data sets. The philosophy throughout is to encourage readers to experiment with the ideas and algorithms in the text. Any business seriously interested in improving its rankings in the major search engines can benefit from the clear examples, sample code, and list of resources provided. Many illustrative examples and entertaining asides MATLAB code Accessible and informal style Complete and self-contained section for mathematics reviewNumerical Algorithms for Personalized Search in Self-organizing Information Networks

and social networks. Representing much of the foundational research in this field, the book develops scalable algorithms that exploit the graphlike properties underlying personalized search and reputation management, and delves into realistic scenarios regarding Web-scale data.Sep Kamvar focuses on eigenvector-based techniques in Web search, introducing a personalized variant of Google's PageRank algorithm, and he outlines algorithms--such as the now-famous quadratic extrapolation technique--that speed up computation, making personalized PageRank feasible. Kamvar suggests that Power Method-related techniques ultimately should be the basis for improving the PageRank algorithm, and he presents algorithms that exploit the convergence behavior of individual components of the PageRank vector. Kamvar then extends the ideas of reputation management and personalized search to distributed networks like peer-to-peer and social networks. He highlights locality and computational considerations related to the structure of the network, and considers such unique issues as malicious peers. He describes the EigenTrust algorithm and applies various PageRank concepts to P2P settings. Discussion chapters summarizing results conclude the book's two main sections.Clear and thorough, this book provides an authoritative look at central innovations in search for all of those interested in the subject.More stimulating mathematics puzzles from bestselling author Paul NahinHow do technicians repair broken communications cables at the bottom of the…

logarithms—an enormous intellectual achievement that would soon lead to the development of their mechanical equivalent in the slide rule: the two would serve humanity as the principal means of calculation until the mid-1970s. Yet, despite Napier's pioneering efforts, his life and work have not attracted detailed modern scrutiny. John Napier is the first contemporary biography to take an in-depth look at the multiple facets of Napier’s story: his privileged position as the eighth Laird of Merchiston and the son of influential Scottish landowners; his reputation as a magician who dabbled in alchemy; his interest in agriculture; his involvement with a notorious outlaw; his staunch anti-Catholic beliefs; his interactions with such peers as Henry Briggs, Johannes Kepler, and Tycho Brahe; and, most notably, his estimable mathematical legacy.Julian Havil explores Napier’s original development of logarithms, the motivations for his approach, and the reasons behind certain adjustments to them. Napier’s inventive mathematical ideas also include formulas for solving spherical triangles, "Napier’s Bones" (a more basic but extremely popular alternative device for calculation), and the use of decimal notation for fractions and binary arithmetic. Havil also considers Napier’s study of the Book of Revelation, which led to his prediction of the Apocalypse in his first book, A Plaine Discovery of the Whole Revelation of St. John—the work for which Napier believed he would be most remembered.John Napier assesses one man’s life and the lasting influence of his advancements on the mathematical sciences and beyond.The Logician and the Engineer: How George Boole and Claude Shannon Created the Information Age

heart of the electronic circuitry in everything we use—from our computers and cars, to home appliances. How did a system of mathematics established in the Victorian era become the basis for such incredible technological achievements a century later? In The Logician and the Engineer, Paul Nahin combines engaging problems and a colorful historical narrative to tell the remarkable story of how two men in different eras—mathematician and philosopher George Boole and electrical engineer and pioneering information theorist Claude Shannon—advanced Boolean logic and became founding fathers of the electronic communications age. Nahin takes readers from fundamental concepts to a deeper and more sophisticated understanding of modern digital machines, in order to explore computing and its possible limitations in the twenty-first century and beyond.Einstein and the Quantum: The Quest of the Valiant Swabian
Par A. Douglas Stone. 2016
The untold story of Albert Einstein's role as the father of quantum theoryEinstein and the Quantum reveals for the first…
time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light—the core of what we now know as quantum theory—than he did about relativity.A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein—not Max Planck or Niels Bohr—was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrödinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.This book offers a new approach to introductory scientific computing. It aims to make students comfortable using computers to do…
science, to provide them with the computational tools and knowledge they need throughout their college careers and into their professional careers, and to show how all the pieces can work together. Rubin Landau introduces the requisite mathematics and computer science in the course of realistic problems, from energy use to the building of skyscrapers to projectile motion with drag. He is attentive to how each discipline uses its own language to describe the same concepts and how computations are concrete instances of the abstract. Landau covers the basics of computation, numerical analysis, and programming from a computational science perspective. The first part of the printed book uses the problem-solving environment Maple as its context, with the same material covered on the accompanying CD as both Maple and Mathematica programs; the second part uses the compiled language Java, with equivalent materials in Fortran90 on the CD; and the final part presents an introduction to LaTeX replete with sample files. Providing the essentials of computing, with practical examples, A First Course in Scientific Computing adheres to the principle that science and engineering students learn computation best while sitting in front of a computer, book in hand, in trial-and-error mode. Not only is it an invaluable learning text and an essential reference for students of mathematics, engineering, physics, and other sciences, but it is also a consummate model for future textbooks in computational science and engineering courses. A broad spectrum of computing tools and examples that can be used throughout an academic career Practical computing aimed at solving realistic problems Both symbolic and numerical computations A multidisciplinary approach: science + math + computer science Maple and Java in the book itself; Mathematica, Fortran90, Maple and Java on the accompanying CD in an interactive workbook formatNumerical Methods for Stochastic Computations: A Spectral Method Approach
