Sundials: Their Construction and Use
by R. Newton Mayall Margaret W. MayallTo many people, the construction of a sundial implies laborious mathematical calculations and a knowledge of astronomy. Nothing could be farther from the truth. This fascinating handbook, used in conjunction with ordinary tools and materials found around the home, makes it easy to design and construct a sundial on almost any surface and in virtually any position. Introductory chapters offer a wealth of information on the sundial's development from ancient times to the present, why the sundial tells time, how to design and make a dial, and more. These chapters are followed by full instructions on how to construct the hour lines for many kinds of sundials, by the graphic or geometric method. The use of this method doesn't require a knowledge of mathematics or astronomy. It simplicity and accuracy, together with the ease and quickness of delineation, make it very practical. Readers will also find fascinating chapters on dial furniture, portable sundials, constructing a heliochronometer (a highly precise solar timekeeper), sundial classification, and other topics. Accompanying the text are 150 well-chosen illustrations, many published for the first time. They depict scale models, as well as a moon dial, a cathedral dial, and other actual dials from around the world, including the world's largest, in Jaipur, India. If you've ever wanted to build your own sundial, or if you simply want to know more about these ancient timepieces that can show the time of day as accurately as many clocks, this clearly written, easy-to-follow guide is "the best book available." -- Commonweal.
Sundials: Their Theory and Construction
by Albert WaughHave you every wanted to build a sundial or to understand how one works? Then you have probably been frustrated as you search vainly for help. Most books on the subject are either rare out-of-print works published centuries ago and available only in highly specialized collections, or highly complicated treatises whose information is hidden behind frightening arrays of involved formulas. But now your search is over. This book is designed to meet sundialing needs at either the simple or the sophisticated level. Albert E. Waugh, professor and administrator at the University of Connecticut for 40 years, and an expert on the subject of sundials and their curious history, presents, on the one hand, a rigorous appraisal of the science of sundials, including mathematical treatment and an explanation of the pertinent astronomical background; on the other hand, he presents simple and non-technical treatments such that several of the dials can be built by children!The subject matter is arranged in 19 chapters, each covering a different aspect of dialing science. All the common types of dials are covered, but the reader can also learn about analemmatic dials, polar dials, equatorial dials, portable dials, memorial dials, armillary spheres, reflected ceiling dials, cross dials, and old-fashioned noon marks. There are also sections on dial furniture, mottoes, the actual layout out of a dial, the equation of time, finding time in other cities, how to find the meridian, how to find time by moonlight -- even how to estimate time from the length of one's own shadow! Directions are given for designing dials for any part of the country, or any place in the world. The author has designed many dials, and his text is filled with helpful hints based on his own personal experience. There are over 100 illustrations, charts, and tables, followed by an appendix which is filled with material which reduces or eliminates the need for calculation on the part of the reader.

Sunscreens in Coastal Ecosystems: Occurrence, Behavior, Effect and Risk (The Handbook of Environmental Chemistry #94)
by Julián Blasco Antonio Tovar-Sánchez David Sánchez-QuilesThis book provides a comprehensive and authoritative review of the chemical analysis of UV filters in coastal waters and their impact on the marine environment. The sun care is today the most important sector within the cosmetics industry, with annual increases in sales. The main components of sunscreens, organic and inorganic UV filters, have been detected in many coastal regions, with the highest concentrations in coastal areas under high anthropogenic pressure. Moreover, these compounds have been found to be bioaccumulated in aquatic biota causing biological and toxicological responses; some organic UV filters act as endocrine disruptors in aquatic biota, affecting survival, behavior, growth, development and reproduction. On the other hand, inorganic UV filters, mainly based on nanoparticles, have been demonstrated to have various impacts on marine organisms, such as inducing oxidative stress in abalones, accumulating in microalgae, affecting the immune response in mussels, bleaching corals, and genotoxicity in fish, among others. All these effects of sunscreens on the marine environment highlight the need for more stringent and environmentally friendly regulations. This book covers the latest analytical methodologies used in assessing the impact of UV filters impact on marine waters, especially on marine biota, and also critiques the global regulation of UV filters and the environmental risk of using sunscreens. Featuring specific case studies of the environmental effects of sunscreens in the Mediterranean Sea and Hawaii, which highlight the importance of balancing human health with environmental health of coastal ecosystems, it will appeal not only to scientists and students from various disciplines (environmental chemistry, biology, ecology, biogeochemistry, fisheries and climate change among others), but also to environmental managers wanting to promote new restrictive regulations on the use of UV filters, and to professionals from the cosmetic industry interested in the development of eco-friendly sunscreens.

Super Crunchers: Why Thinking-by-Numbers Is the New Way to be Smart
by Ian AyresCompanies used to rely on human experts and their years of experience to guide them. Now, cutting-edge organizations are mining the data and crunching numbers instead, to come up with more accurate, less biased predictions. As Freakonomics detailed, statistical analysis can reveal the secret levers of causation. But economist Ian Ayres argues that that's only part of the story: super crunching is revolutionizing the way we all make decisions. Beginning with examples of the mathematician who out-predicted wine buffs in determining the best vintages, and the sports scouts who now use statistics rather than intuition to pick winners, Super Crunchers exposes the world of data-miners, introducing the people and the techniques. It illuminates the hidden patterns all around us. No businessperson, academic, student, or consumer (statistically that's everyone) should make another move without getting to grips with thinking-by-numbers ? the new way to be smart, savvy and statistically superior.
Super Fly: The Unexpected Lives of the World's Most Successful Insects
by Jonathan BalcombeFrom an expert in animal consciousness, a book that will turn the fly on the wall into the elephant in the room."After reading Super Fly, you will never take a fly for granted again. Thank you, Jonathan Balcombe, for reminding us of the infinite marvels of everyday creatures." —Sy Montgomery, Author of How to Be a Good Creature For most of us, the only thing we know about flies is that they're annoying, and our usual reaction is to try to kill them. In Super Fly, the myth-busting biologist Jonathan Balcombe shows the order Diptera in all of its diversity, illustrating the essential role that flies play in every ecosystem in the world as pollinators, waste-disposers, predators, and food source; and how flies continue to reshape our understanding of evolution. Along the way, he reintroduces us to familiar foes like the fruit fly and mosquito, and gives us the chance to meet their lesser-known cousins like the Petroleum Fly (the only animal in the world that breeds in crude oil) and the Chocolate Midge (the sole pollinator of the Cacao tree). No matter your outlook on our tiny buzzing neighbors, Super Fly will change the way you look at flies forever. Jonathan Balcombe is the author of four books on animal sentience, including the New York Times bestselling What A Fish Knows, which was nominated for the PEN/E.O. Wilson Award for Science Writing. He has worked for years as a researcher and educator with the Humane society to show us the consciousness of other creatures, and here he takes us to the farthest reaches of the animal kingdom.

Super Polluters: Tackling the World’s Largest Sites of Climate-Disrupting Emissions (Society and the Environment)
by Wesley Longhofer Don Grant Andrew JorgensonPower plants are essential to achieving the standard of living that modern societies demand and the social and economic infrastructure on which they depend. Yet their indispensability has allowed them to evade responsibility for their vast carbon emissions. Fossil-fueled power plants are the single largest sites of anthropogenic greenhouse gases, making them one of the greatest threats to our planet’s climate. Significant as they are, we lack a comprehensive understanding of the social causes that enable power plant emissions and continue to delay their reduction.Super Polluters offers a groundbreaking global analysis of carbon pollution caused by the generation of electricity, pinpointing who bears the most responsibility for the energy sector’s vast emissions and what can be done about them. The sociologists Don Grant, Andrew Jorgenson, and Wesley Longhofer analyze a novel dataset on the carbon dioxide emissions and structural attributes of thousands of fossil-fueled power plants around the world, identifying which plants discharge the most carbon. They investigate the global, organizational, and political conditions that explain these hyper-emitting facilities’ behavior and call into question the claim that improvements in technical efficiency will always reduce emissions. Grant, Jorgenson, and Longhofer demonstrate which energy and climate policies are most effective at abating power-plant pollution, emphasizing how mobilized citizen activism shapes those outcomes. A comprehensive account of who bears the blame for our warming planet, Super Polluters points to more feasible and effective emission reduction strategies that target the world’s most profligate polluters.
