"Art and Science mingle in Julia Rothman's visual tour of the natural world. If you've ever wanted to see how mountains are formed or wondered about the life cycle of a mushroom or the different types of feathers on a bird, you'll delight in exploring Rothman's drawings, diagrams, and dissections. Her spirited exploration of earth and water, flora and fauna will open your eyes to new views of nature's wonders"--Page [4] of cover.

Adored for their fairy-like beauty and power of flight, butterflies and moths captivate enthusiasts world-wide. As well as being attractive to watch, these exquisite insects are also of huge biological importance. Not only are they useful pollinators, they also act as scientific 'indicators' of changing levels of light, heat and availability of food. Consequently, some species are the subject of intense study to see how well they are adapting to environmental challenges. This book has a photographic reference section that covers the life cycle of these creatures, with detailed descriptions of internal anatomy and the powerful structure of their wings. There is information on classification, as well as close-up anatomical images. A geographical directory profiles over 565 of the world's best-loved and most intriguing butterflies, moths, and their caterpillars, with each entry containing identification notes and quick-reference panels on distribution, habitat, food, and wingspan. Butterflies are immensely variable and some have evolved physical traits to adapt to their habitat or ward off predators.

"The invention of numerals is perhaps the greatest abstraction the human mind has ever created. Virtually everything in our lives is digital, numerical, or quantified. The story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is an adventure filled saga of Amir Aczel's lifelong obsession: to find the original sources of our numerals. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with the early Babylonian cuneiform numbers, followed by the later Greek and Roman letter numerals. Then Aczel asks the key question: where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory, to go on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero--the keystone of our entire system of numbers--on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves--who finally reveal where our numbers come from"-- Provided by publisher.

More than 300 specimens are featured in this detailed photographic guide to recognizing plant and animal fossils, with examples from around the world.
