fun. An immensely likeable man.' Damon Hill The world's foremost designer in Formula One, Adrian Newey OBE is arguably one of Britain's greatest engineers and this is his fascinating, powerful memoir. How to Build a Car explores the story of Adrian's unrivalled 35-year career in Formula One through the prism of the cars he has designed, the drivers he has worked alongside and the races in which he's been involved. A true engineering genius, even in adolescence Adrian's thoughts naturally emerged in shape and form – he began sketching his own car designs at the age of 12 and took a welding course in his school summer holidays. From his early career in IndyCar racing and on to his unparalleled success in Formula One, we learn in comprehensive, engaging and highly entertaining detail how a car actually works. Adrian has designed for the likes of Mario Andretti, Nigel Mansell, Alain Prost, Damon Hill, David Coulthard, Mika Hakkinen, Mark Webber and Sebastian Vettel, always with a shark-like purity of purpose: to make the car go faster. And while his career has been marked by unbelievable triumphs, there have also been deep tragedies; most notably Ayrton Senna's death during his time at Williams in 1994. Beautifully illustrated with never-before-seen drawings, How to Build a Car encapsulates, through Adrian's remarkable life story, precisely what makes Formula One so thrilling – its potential for the total synchronicity of man and machine, the perfect combination of style, efficiency and speedPar 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.Par Sajid Fiaz. 2024

During the last few years, Greece has become a subject of increasing attention worldwide. Once praised for its ability to…
innovate and reform during the EU integration process, applauded for its remarkable job in managing the 2004 Olympics, the country fell into a financial crisis of unprecedented magnitude in 2008. Much has been said on this matter, and amid the morass of information a staggering number of untruths have been disseminated.In fact, the challenges of vulnerability and the paradigms of adaptation go way beyond finance and economy in Greece. Mega-fires, earthquakes, landslides and floods, migrations, sociopolitical upheavals, and armed conflicts generate emergency situations repeatedly. Because of its bridging role between natural and social sciences, geography can provide insights into the entire breadth of hazardous and chaotic events driving adaptation and change. Against all these threats, Greece has developed an enhanced resilience capacity. The purpose of this book is to help unravel the complexities of a fascinating country beyond clichés.This book is intended for students, researchers, scholars, and engineers interested in geography, land planning, urban studies, and environmental management. The crises issue intended as a guideline allows widening the audience to include the media, governmental and non-governmental agencies, and the public at large.Par Martin H. Krieger. 2024
Many philosophers, physicists, and mathematicians have wondered about the remarkable relationship between mathematics with its abstract, pure, independent structures on…
one side, and the wilderness of natural phenomena on the other. Famously, Wigner found the "effectiveness" of mathematics in defining and supporting physical theories to be unreasonable, for how incredibly well it worked. Why, in fact, should these mathematical structures be so well-fitting, and even heuristic in the scientific exploration and discovery of nature? This book argues that the effectiveness of mathematics in physics is reasonable. The author builds on useful analogies of prime numbers and elementary particles, elementary structure kinship and the structure of systems of particles, spectra and symmetries, and for example, mathematical limits and physical situations. The two-dimensional Ising model of a permanent magnet and the proofs of the stability of everyday matter exemplify such effectiveness, and the power of rigorous mathematical physics. Newton is our original model, with Galileo earlier suggesting that mathematics is the language of Nature.Par Anne Hemkendreis, Anna-Sophie Jürgens. 2024

pop cultural studies, environmental studies, sciences studying ice and artists to explore the power of (popular) arts and aesthetics to communicate ice research and the urgency of environmental action. Examining the aesthetic strategies employed in images, (popular) visual fiction and narratives to convey meaning and awareness – and how they can be made fruitful for science communication – the project will generate new perspectives on how our collective environmental responsibility can be addressed and communicated across disciplines and divers audiences. In doing so, the volume will illuminate the cultural power of ice research and contribute to a better understanding of the cultural work that emerges from our ecological crisis.Par Gregory Argentieri. 2024
There has been an enormous growth of interest in the field of toxicologic pathology and particularly on its impact on…
nonclinical safety assessment in global drug development and in the environment. Toxicologic pathologists play an important role in detecting test article-related adverse effects by characterizing morphologic changes in animal tissues and/or body fluids under prescribed study conditions or less clearly defined conditions in the environment and in the interpretation of these findings relative to human risk. In fact, pathology evaluation is often the single most important decision-making factor in nonclinical safety assessments as 80% of drug candidate attrition has been attributed to pathology findings in toxicity studies. There are currently no primers or basic overviews covering the field of toxicologic pathology, whereas there are at least several basic books that cover the sister field of toxicology.Toxicologic Pathology: A Primer is a practical, easy-to-use reference designed to contain core information provided by board-certified veterinary pathologists, all experts in the field. The Primer contains the basic, underlying principles of toxicologic pathology at the introductory level; thus it will be valuable to the veterinary pathology student who may be considering a career in the field as well as a companion to the seasoned toxicologic pathologist who wants a succinct refresher. The Primer is arranged as chapters presenting each major organ system preceded by an overview chapter covering the field of toxicologic pathology followed by a “concept” chapter describing the role of toxicologic pathology in drug development. Photomicrographs and illustrations provide visual context.The organ system chapters provide histopathologic descriptions of lesions observed in toxicity studies of test articles in drug development and testing of chemicals that may negatively impact the environment. Each organ system chapter provides additional information related to a particular lesion to aid the reader in better understanding its toxicologic significance relative to human risk.Each organ system chapter contains: A brief introduction A succinct description of the anatomy and physiology of the system Descriptions of the most important pathological lesions Differential diagnoses Biological consequences, pathogenesis, and/or mechanism of lesion formation Associated clinical pathology correlates Nonclinical safety scientists such as study directors, non-pathology-oriented contributing scientists such as senior toxicology report reviewers, scientific management of Contract Research Organizations (CROs), and students should find the Primer useful in helping them understand the fundamentals of toxicologic pathology.This book offers an in-depth exploration of battery separators, a critical component in Lithium-ion batteries (LIBs). Serving as insulators between…
electrodes to prevent internal short circuits, these separators play a crucial role in retaining liquid electrolyte and facilitating the migration of lithium ions during battery cycling. In the face of increasing demand for high-performance LIBs across diverse applications, the development of superior separators is imperative. Among the various advancements in battery separator research, electrospun nanofibrous separators have gained significant attention. These separators exhibit compelling characteristics, including large pore size (typically above 500 nm), high porosity (typically above 70%), and an interconnected porous structure, all of which enhance ion transportation efficiency and battery cycling performance. However, a notable focus in previous studies has been on electrochemical inert materials as battery separators, which do not contribute to the battery's capacity. This book presents a comprehensive study that introduces a novel concept: the development of a redox-active separator based on electrospun polypyrrole (PPy) composite nanofibers to significantly enhance battery capacity. The book begins by exploring the effects of separators on battery performance, providing valuable insights and guidance for separator design. Then, a detailed investigation into the kinetics of in-situ polymerization of PPy with electrospun fibrous membranes as templates follows, shedding light on the mechanisms behind fabricating the proposed separator. Finally, this book presents the fabrication and characterization of the proposed separator, showcasing potential of the separator for enhancing battery capacity. This book is intended for researchers, engineers, and professionals in the field of battery technology, materials science, and electrochemistry. It is also a valuable resource for graduate students and academics seeking advanced insights into the development of high-performance lithium-ion batteries and innovative separator technologies.Par Konstadinos Mattas, George Baourakis, Constantin Zopounidis, Christos Staboulis. 2024
