Book Description
Since the early 1990s, advances in toxicology have allowed scientists to detect traces of adulterant substances in everyday products – even down to parts per billion concentrations. We can now detect the presence of harmful ingredients at levels so low that they actually cause no harm. Nonetheless, we get scared. We are now able to overreact to harmless, negligible sources of contamination and flock to ‘natural’, ‘organic’ and ‘chemical-free’ alternative products at elevated prices instead. This urge is driven in part by a set of interesting psychological quirks called the naturalness preference or biophilia. While exposure to many aspects of nature improves our physical and mental wellbeing, marketers are taking advantage of our naturalness preference by selling us ‘organic’ and ‘natural’ products with no functional advantage, sometimes to the detriment of the environment, and that have the unfortunate added effect of peddling a fear of conventional products that do not make such natural connotations. This fear of chemicals, exaggerated by marketers, has led some of us to seek nature in the form of expensive consumer product, which offer almost none of the benefits of spending time outdoors in real nature (which is free of charge). We thus chase nature in the wrong form. We feel guilt, anxiety and mental stress from being coaxed into paying a hefty premium price for "natural" products that are neither safer nor more effective than conventional ones, and forget to appreciate real nature in the process. This book explores the history of chemical fears and the recent events that amplified it. It describes how consumers, teachers, doctors, lawmakers and journalists can help make better connections with the public by telling stories that are more engaging about chemistry and materials science. Written in a sympathetic way, this book explains both sides of the argument for anyone with an interest in science.

Book Description
Throughout the history of the Western world, science has possessed an extraordinary amount of authority and prestige. And while its pedestal has been jostled by numerous evolutions and revolutions, science has always managed to maintain its stronghold as the knowing enterprise that explains how the natural world works: we treat such legendary scientists as Galileo, Newton, Darwin, and Einstein with admiration and reverence because they offer profound and sustaining insight into the meaning of the universe. In The Intelligibility of Nature, Peter Dear considers how science as such has evolved and how it has marshaled itself to make sense of the world. His intellectual journey begins with a crucial observation: that the enterprise of science is, and has been, directed toward two distinct but frequently conflated ends—doing and knowing. The ancient Greeks developed this distinction of value between craft on the one hand and understanding on the other, and according to Dear, that distinction has survived to shape attitudes toward science ever since. Teasing out this tension between doing and knowing during key episodes in the history of science—mechanical philosophy and Newtonian gravitation, elective affinities and the chemical revolution, enlightened natural history and taxonomy, evolutionary biology, the dynamical theory of electromagnetism, and quantum theory—Dear reveals how the two principles became formalized into a single enterprise, science, that would be carried out by a new kind of person, the scientist. Finely nuanced and elegantly conceived, The Intelligibility of Nature will be essential reading for aficionados and historians of science alike.

Book Description
An “essential” (Times UK) and “meticulously researched” (Forbes) book by “the skeptical environmentalist” argues that panic over climate change is causing more harm than good Hurricanes batter our coasts. Wildfires rage across the American West. Glaciers collapse in the Artic. Politicians, activists, and the media espouse a common message: climate change is destroying the planet, and we must take drastic action immediately to stop it. Children panic about their future, and adults wonder if it is even ethical to bring new life into the world. Enough, argues bestselling author Bjorn Lomborg. Climate change is real, but it's not the apocalyptic threat that we've been told it is. Projections of Earth's imminent demise are based on bad science and even worse economics. In panic, world leaders have committed to wildly expensive but largely ineffective policies that hamper growth and crowd out more pressing investments in human capital, from immunization to education. False Alarm will convince you that everything you think about climate change is wrong -- and points the way toward making the world a vastly better, if slightly warmer, place for us all.

Book Description
A beautifully illustrated, totally engrossing celebration of the piano, and the composers and performers who have made it their own. With honed sensitivity and unquestioned expertise, Stuart Isacoff—pianist, critic, teacher, and author of Temperament: How Music Became a Battleground for the Great Minds of Western Civilization—unfolds the ongoing history and evolution of the piano and all its myriad wonders: how its very sound provides the basis for emotional expression and individual style, and why it has so powerfully entertained generation upon generation of listeners. He illuminates the groundbreaking music of Mozart, Beethoven, Liszt, Schumann, and Debussy. He analyzes the breathtaking techniques of Glenn Gould, Oscar Peterson, Vladimir Ashkenazy, Arthur Rubinstein, and Van Cliburn, and he gives musicians including Alfred Brendel, Murray Perahia, Menahem Pressler, and Vladimir Horowitz the opportunity to discuss their approaches. Isacoff delineates how classical music and jazz influenced each other as the uniquely American art form progressed from ragtime, novelty, stride, boogie, bebop, and beyond, through Scott Joplin, Fats Waller, Duke Ellington, Bill Evans, Thelonious Monk, Chick Corea, Herbie Hancock, Cecil Taylor, and Bill Charlap. A Natural History of the Piano distills a lifetime of research and passion into one brilliant narrative. We witness Mozart unveiling his monumental concertos in Vienna’s coffeehouses, using a special piano with one keyboard for the hands and another for the feet; European virtuoso Henri Herz entertaining rowdy miners during the California gold rush; Beethoven at his piano, conjuring healing angels to console a grieving mother who had lost her child; Liszt fainting in the arms of a page turner to spark an entire hall into hysterics. Here is the instrument in all its complexity and beauty. We learn of the incredible craftsmanship of a modern Steinway, the peculiarity of specialty pianos built for the Victorian household, the continuing innovation in keyboards including electronic ones. And most of all, we hear the music of the masters, from centuries ago and in our own age, brilliantly evoked and as marvelous as its most recent performance. With this wide-ranging volume, Isacoff gives us a must-have for music lovers, pianists, and the armchair musician.

Book Description
Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.
