Marsilio Ficino, a leading scholar of the Italian Renaissance who translated all the works of Plato into Latin, examines Plato’s Timaeus, the most widely influential and hotly debated of the Platonic writings. Offering a probable account of the creation and nature of the cosmos, the discussion incorporates such questions as What is the function of arithmetic and geometry in the design of creation? What is the nature of mind, soul, matter, and time? and What is our place in the universe? To his main commentary Ficino adds an appendix, which amplifies and elucidates Plato’s meanings and reveals fascinating details about Ficino himself.

In this age of climate change, killer germs, and obesity, it's easy to feel as if we've fallen out of synch with the global ecosystem. This ecological anxiety has polarized a new generation of Americans: many are drawn to natural solutions and organic lifestyles, while others rally around high-tech development and industrial efficiencies. Johnson argues that both views, when taken to extremes, can be harmful, even deadly. Johnson, raised in the crunchy-granola epicenter of Nevada City, California, lovingly and rigorously scrutinizes his family's all-natural mindset, a quest that brings him into the worlds of an outlaw midwife, radical doctors, renegade farmers and one hermit forester. Along the way, he uncovers paradoxes at the heart of our ecological condition: Why, even as medicine improves, are we becoming less healthy? Why are more American women dying in childbirth? Why do we grow fatter the more we diet? Why have so many attempts to save the environment backfired? In All Natural*--a sparklingly intelligent, wry, and scrupulously reported narrative--Johnson teases fact from faith and offers a rousing and original vision for a middle ground between natural and technological solutions that will assuage frustrated environmentalists, perplexed parents, and confused consumers alike.

As a child, Aldo Leopold was always looking for adventures in nature. This led Leopold to become a forester, wildlife scientist, author, and ultimately one of the most well-known conservationists in American history. Award-winning author Marybeth Lorbiecki brings Leopold to life in this biography enhanced with historic photographs and a school resource section. Marybeth Lorbiecki is the author of more than twenty-five books for children and adults, and she teaches upper-level college writing and children's literature as an adjunct university professor. Her adult biography Aldo Leopold: A Fierce Green Fire earned a Minnesota Book Award.

This is a graduate-level textbook for students in the natural sciences. After reviewing the necessary math, it describes the logical path from Newton's laws of motion to our modern understanding of fluid mechanics. It does not describe engineering applications but instead focuses on phenomena found in nature. Once developed, the theory is applied to three familiar examples of flows that can be observed easily in Earth's atmosphere, oceans, rivers and lakes: vortices, interfacial waves, and hydraulic transitions. The student will then have both (1) the tools to analyze a wide range of naturally-occurring flows and (2) a solid foundation for more advanced studies in atmospheric dynamics and physical oceanography. Appendices give more detailed explanations and optional topics.

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.

A physician offers an impassioned and meticulously researched exposé of the alternative medicine industry, separating the sense from the nonsense. A half century ago, acupuncture, homeopathy, naturopathy, Chinese herbs, Christian exorcisms, dietary supplements, chiropractic manipulations, and ayurvedic remedies were considered on the fringe of medicine. Now these practices—known variably as alternative, complementary, holistic, or integrative medicine—have become mainstream, used by half of all Americans today to treat a variety of conditions, from excess weight to cancer. But alternative medicine is an unregulated industry under no legal obligation to prove its claims or admit its risks, and many popular alternative therapies are ineffective, expensive, or even deadly. In Do You Believe in Magic?, health advocate Dr. Offit debunks the treatments that don’t work and tells us why, and takes on the media celebrities who promote alternative medicine. Using dramatic real-life stories, he separates the sense from the nonsense, explaining why any therapy—alternative or traditional—should be scrutinized. As Dr. Offit explains, some popular therapies are remarkably helpful due to the placebo response, but “there’s no such thing as alternative medicine. There’s only medicine that works and medicine that doesn’t.”

From a startling new voice in American fiction comes a dark, powerful novel about a tragic city and its inhabitants over the course of one Halloween weekend. Set in a decaying Midwestern urban landscape, with its goings-on and entire atmosphere dominated and charged by one Jesuit prep school and its students, parents, faculty, and alumni, THE NATURAL ORDER OF THINGS is a window into the human condition. From the opening chapter and its story of the doomed quarterback, Frank McSweeney, aka The Minotaur, for whom prayers prove not enough, to the end, wherein the school's former headmaster is betrayed by his peers in the worst way possible, we see people and their oddness and ambitions laid out bare before us.
