Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking, open access volume analyses and compares data practices across several fields through the analysis of specific cases of data journeys. It brings together leading scholars in the philosophy, history and social studies of science to achieve two goals: tracking the travel of data across different spaces, times and domains of research practice; and documenting how such journeys affect the use of data as evidence and the knowledge being produced. The volume captures the opportunities, challenges and concerns involved in making data move from the sites in which they are originally produced to sites where they can be integrated with other data, analysed and re-used for a variety of purposes. The in-depth study of data journeys provides the necessary ground to examine disciplinary, geographical and historical differences and similarities in data management, processing and interpretation, thus identifying the key conditions of possibility for the widespread data sharing associated with Big and Open Data. The chapters are ordered in sections that broadly correspond to different stages of the journeys of data, from their generation to the legitimisation of their use for specific purposes. Additionally, the preface to the volume provides a variety of alternative “roadmaps” aimed to serve the different interests and entry points of readers; and the introduction provides a substantive overview of what data journeys can teach about the methods and epistemology of research.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of essays traces a scientific journey bookmarked by remarkable mentors and milestones of science. It provides fascinating reading for everyone interested in the history, public appreciation, and value of science, as well as giving first-hand accounts of many key events and prominent figures. The author was one of the “sputnik kids” growing up in the US at the start of the space age. He built a working laser just two years after they were first invented, an experience that convinced him to become a physicist. During his 50-year career in physics, many personalities and notable events in science and technology helped to form his view of how science contributes to the modern world​, including his conviction that the impact of science can be most effective when introduced within the context of the humanities - especially history, literature and the arts. From the Foreword by former U.S. Congressman, Rush D. Holt: In this volume, we have the wide-ranging thoughts and observations of Fred Dylla, an accomplished physicist with an engineer’s fascination for gadgets, a historian’s long perspective, an artist’s aesthetic eye, and a teacher’s passion for sharing ideas. Throughout his varied career [...] his curiosity has been his foremost characteristic and his ability to see the connection between apparently disparate things his greatest skill. [...] Here he examines the roots and growth of innovation in examples from Bell Laboratories, Edison Electric Light Company, and cubist painter Georges Braque. He considers the essential place of publishing in science, that epochal intellectual technique for learning how the world works. He shows the human enrichment and practical benefits that derive from wise investments in scientific research, as well as the waste resulting from a failure to embrace appropriate technologies.

Book excerpt: “An engaging voyage into some of the great mysteries and wonders of our world." --Alan Lightman, author of Einstein’s Dream and The Accidental Universe “No one is better at making the recondite accessible and exciting.” —Bill Bryson Brain Pickings and Kirkus Best Science Book of the Year Every week seems to throw up a new discovery, shaking the foundations of what we know. But are there questions we will never be able to answer—mysteries that lie beyond the predictive powers of science? In this captivating exploration of our most tantalizing unknowns, Marcus du Sautoy invites us to consider the problems in cosmology, quantum physics, mathematics, and neuroscience that continue to bedevil scientists and creative thinkers who are at the forefront of their fields. At once exhilarating, mind-bending, and compulsively readable, The Great Unknown challenges us to consider big questions—about the nature of consciousness, what came before the big bang, and what lies beyond our horizons—while taking us on a virtuoso tour of the great breakthroughs of the past and celebrating the men and women who dared to tackle the seemingly impossible and had the imagination to come up with new ways of seeing the world.

Book excerpt: This book explores facets of Otto Neugebauer's career, his impact on the history and practice of mathematics, and the ways in which his legacy has been preserved or transformed in recent decades, looking ahead to the directions in which the study of the history of science will head in the twenty-first century. Neugebauer, more than any other scholar of recent times, shaped the way we perceive premodern science. Through his scholarship and influence on students and collaborators, he inculcated both an approach to historical research on ancient and medieval mathematics and astronomy through precise mathematical and philological study of texts, and a vision of these sciences as systems of knowledge and method that spread outward from the ancient Near Eastern civilizations, crossing cultural boundaries and circulating over a tremendous geographical expanse of the Old World from the Atlantic to India.

Book excerpt: 'Darryl Cunningham's simplicity of style is deceptive. I never fail to learn from his work, always educational and deeply human too. This is the sort of book you think you have bought for your child, then refuse to give up until you have finished it first. Buy two copies to be on the safe side.'— Robin Ince Much is known about scientists such as Darwin, Newton, and Einstein, but what about lesser-known scientists—people who have not achieved a high level of fame, but who have contributed greatly to human knowledge? What were their lives like? What were their struggles, aims, successes, and failures? How do their discoveries fit into the bigger picture of science as a whole? Overlooked, sidelined, excluded, discredited: key figures in scientific discovery come and take their bow in an alternative Nobel Prize gallery in a colourful graphic novel by Darryl Cunningham. Antoine Lavoisier: the father of French chemistry who gave oxygen its name, Lavoisier was a wealthy man who found himself on the wrong side of a revolution and paid the price with his life. The contribution to his work by his wife Marie-Anne Lavoisier is only now being fully recognised. Mary Anning: a poor, working-class woman who made her living fossil-hunting along the beach cliffs of southern England. Anning found herself excluded from the scientific community because of her gender and social class. Wealthy, male, experts took credit for her discoveries. George Washington Carver: born a slave, Carver become one of the most prominent botanists of his time, as well as a teacher at the Tuskegee Institute. Carver devised over 100 products using one major ingredient—the peanut—including dyes, plastics and gasoline. Alfred Wegener: a German meteorologist, balloonist, and arctic explorer, his theory of continental drift was derided by other scientists and was only accepted into mainstream thinking after his death. He died in Greenland on an expedition, his body lost in the ice and snow. Nikola Tesla: a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system. A competitor of Edison, Tesla died in poverty despite his intellectual brilliance. Jocelyn Bell Burnell: a Northern Irish astrophysicist. As a postgraduate student, she discovered the first radio pulsars (supernova remnants) while studying and advised by her thesis supervisor Antony Hewish, for which Hewish shared the Nobel Prize in physics while Bell Burnell was excluded. Fred Hoyle: an English astronomer noted primarily for the theory of stellar nucleosynthesis – the process whereby most of the elements on the Periodic Table are created. He was also noted for the controversial positions he held on a wide range of scientific issues, often in direct opposition to prevailing theories. This eccentric approach contributed to him to being overlooked by the Nobel Prize committee for his stellar nucleosynthesis work. Any one of these figures could have been awarded a Nobel prize. Not every scientific discoverer was lauded in their time, for reasons of gender, race, or lack of wealth, or (in the case of Lavoisier) being too wealthy: in the 21st century, there are many more reparations and reputations to be made.

Panic in Level 4 is a grand tour through the eerie and unforgettable universe of Richard Preston, filled with incredible characters and mysteries that refuse to leave one’s mind. Here are dramatic true stories from this acclaimed and award-winning author, including: • The phenomenon of “self-cannibals,” who suffer from a rare genetic condition caused by one wrong letter in their DNA that forces them to compulsively chew their own flesh–and why everyone may have a touch of this disease. • The search for the unknown host of Ebola virus, an organism hidden somewhere in African rain forests, where the disease finds its way into the human species, causing outbreaks of unparalleled horror. • The brilliant Russian brothers–“one mathematician divided between two bodies”–who built a supercomputer in their apartment from mail-order parts in an attempt to find hidden order in the number pi (π). In fascinating, intimate, and exhilarating detail, Richard Preston portrays the frightening forces and constructive discoveries that are currently roiling and reordering our world, once again proving himself a master of the nonfiction narrative and, as noted in The Washington Post, “a science writer with an uncommon gift for turning complex biology into riveting page-turners.”

This book was released on 2020-07-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An urgent and illuminating portrait of forest migration, and of the people studying the forests of the past, protecting the forests of the present, and planting the forests of the future. Forests are restless. Any time a tree dies or a new one sprouts, the forest that includes it has shifted. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles—humans felling trees by the billions, invasive pests transported through global trade—threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before, and forests are struggling to keep up. A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya, and Monterey pine. Journalist Zach St. George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand, and tender new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St. George meets lively people on conservation’s front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists, and foresters, each with their own role to play in the fight for the uncertain future of our environment. An eye-opening investigation into forest migration past and present, The Journeys of Trees examines how we can all help our trees, and our planet, survive and thrive.

Available in PDF, EPUB and Kindle. Book excerpt: Scientists today working on controversial issues from climate change to drought to COVID-19 are finding themselves more often in the middle of deeply traumatizing or polarized conflicts they feel unprepared to referee. It is no longer enough for scientists to communicate a scientific topic clearly. They must now be experts not only in their fields of study, but also in navigating the thoughts, feelings, and opinions of members of the public they engage with, and with each other. And the conversations are growing more fraught. In Getting to the Heart of Science Communication, Faith Kearns has penned a succinct guide for navigating the human relationships critical to the success of practice-based science. This meticulously researched volume takes science communication to the next level, helping scientists to see the value of listening as well as talking, understanding power dynamics in relationships, and addressing the roles of trauma, loss, grief, and healing.

Available in PDF, EPUB and Kindle. Book excerpt: Is God a delusion? Are science and Christian faith incompatible? Ten scientists tell their stories. There is a popular myth at large in both modern society and in many churches. According to this myth science and Christianity have been engaged in a long battle over the centuries. For many secularists this means that we must embrace science and reject religion, whilst for some Christians it means the exact opposite. But are science and Christian faith really in a conflict? In this book ten respected scientists share their life stories and their reflections on science and faith. What led them to become scientists? Why did they embrace Christianity? And how do they relate their religious beliefs to the science that they do in the lab? The stories that they tell help us to see that when it comes to answering some of 'life's big questions' we do well to listen for the insights from both science and faith. Contributors include: Dr Francis Collins, Professor Alister McGrath, Dr Ard Louis, Dr Jennifer Wiseman, Professor Bill Newsome, Rev Dr John Polkinghorn, Rev Dr Alasdair Coles, Dr Deborah B. Haarsma, Professor Rosalind Picard, Professor John Bryant. 'The level of human insight matching scientific expertise in these chapters is high, and they have left me feeling that here are folk with whom, as a mere theologian, I would love to spend some time. I hope other readers will enjoy this set of testimonies as much as I have done.' - Professor J. I. Packer, Regent College, Vancouver, Canada 'Just the book to give to anyone who thinks science disproves religion. Powerful testimonies from ten distinguished scientists reveal why their faith in God enhances their research. A very worthwhile read!' - Professor Gordon Wenham, Trinity College, Bristol, UK 'These short, readable accounts by ten scientists are a pleasure to read and an inspiration to anyone who seeks to integrate Christian belief and science. Each one is a specialist in a different scientific discipline, and they tell very different life stories, yet they all affirm the Christian privilege of scientific discovery and understanding.' - Professor Keith Fox, School of Biological Sciences, University of Southampton, and Chair of Christians in Science 'Brilliantly demonstrates that science and Christianity are not enemies but perfectly compatible.' - Dr Krish Kandiah, Evangelical Alliance

Available in PDF, EPUB and Kindle. Book excerpt: A “beautifully written” (Kirkus Reviews, starred review) memoir-manifesto from the first female director of the National Science Foundation about the entrenched sexism in science, the elaborate detours women have take to bypass the problem, and how to fix the system. If you think sexism thrives only on Wall Street or Hollywood, you haven’t visited a lab, a science department, a research foundation, or a biotech firm. Rita Colwell is one of the top scientists in America: the groundbreaking microbiologist who discovered how cholera survives between epidemics and the former head of the National Science Foundation. But when she first applied for a graduate fellowship in bacteriology, she was told, “We don’t waste fellowships on women.” A lack of support from some male superiors would lead her to change her area of study six times before completing her PhD. A Lab of One’s Own is an “engaging” (Booklist) book that documents all Colwell has seen and heard over her six decades in science, from sexual harassment in the lab to obscure systems blocking women from leading professional organizations or publishing their work. Along the way, she encounters other women pushing back against the status quo, including a group at MIT who revolt when they discover their labs are a fraction of the size of their male colleagues. Resistance gave female scientists special gifts: forced to change specialties so many times, they came to see things in a more interdisciplinary way, which turned out to be key to making new discoveries in the 20th and 21st centuries. Colwell would also witness the advances that could be made when men and women worked together—often under her direction, such as when she headed a team that helped to uncover the source of anthrax used in the 2001 letter attacks. A Lab of One’s Own is “an inspiring read for women embarking on a career or experiencing career challenges” (Library Journal, starred review) that shares the sheer joy a scientist feels when moving toward a breakthrough, and the thrill of uncovering a whole new generation of female pioneers. It is the science book for the #MeToo era, offering an astute diagnosis of how to fix the problem of sexism in science—and a celebration of women pushing back.
