This book explores the development of hybrid corn, the history of eugenics, human genetics, the nature-nurture debate, the origins of the Marxian concept of proletarian science, the shift in the meaning of "fitness" in evolutionary theory, the practice of normal science in Nazi Germany, and the making and selling of science textbooks. While the topics are diverse, a common theme unites them - each explores links between biological science, social power, and public policy.
Flower essences are living energies that can bring more vigor and vitality to our lives. They teach us how to evolve, how to utilize our elements, how to nourish and be nourished, how to be of beauty, and how to orient ourselves. They teach us internal integrity and structure. They teach us how to be. Many of Mary Ann's interpretations of flower essences here are tailored to fit the needs of particular circumstances. Formatted with keywords for quick reference to whatever issues you would like to explore, this compilation of her columns from the past ten years serves as a friend, guide, and resource to help you grow and blossom. 130 Essences Including: • Apple Blossom • Beech • Chaparral • Cherry • Plum • Echinacea • Elm • Fireweed • Garlic • Golden Yarrow • Honeysuckle • Indian Pink • Lavender • Lemon • Olive • Pine • Sage • St. Johnswort • Trillium • White Chestnut • Zinnia
The lavish array of organisms known as "biodiversity" is an intricately linked web that makes the Earth a uniquely habitable plane. In this book, a noted science writer examines the threats posed to humans by the loss of biodiversity and explains key findings from the ecological sciences. It is the first book of its kind to clearly explains the practical consequences of declining biodiversity of ecosystem hjealth and function and, consequently, on human society.
The study of chaotic systems has become a major scientific pursuit in recent years, shedding light on the apparently random behaviour observed in fields as diverse as climatology and mechanics. InThe Essence of Chaos Edward Lorenz, one of the founding fathers of Chaos and the originator of its seminal concept of the Butterfly Effect, presents his own landscape of our current understanding of the field. Lorenz presents everyday examples of chaotic behaviour, such as the toss of a coin, the pinball's path, the fall of a leaf, and explains in elementary mathematical strms how their essentially chaotic nature can be understood. His principal example involved the construction of a model of a board sliding down a ski slope. Through this model Lorenz illustrates chaotic phenomena and the related concepts of bifurcation and strange attractors. He also provides the context in which chaos can be related to the similarly emergent fields of nonlinearity, complexity and fractals. As an early pioneer of chaos, Lorenz also provides his own story of the human endeavour in developing this new field. He describes his initial encounters with chaos through his study of climate and introduces many of the personalities who contributed early breakthroughs. His seminal paper, "Does the Flap of a Butterfly's Wing in Brazil Set Off a Tornado in Texas?" is published for the first time.
Jay Maisel, hailed as one of the most brilliant, gifted photographers of all time, is much more than that. He is a mentor, teacher, and trailblazer to many photographers, and a hero to those who feel Jay’s teaching has changed the way they see and create their own photography. He is a living legend whose work is studied around the world, and whose teaching style and presentation garner standing ovations and critical acclaim every time he takes the stage. Now, for the first time ever, Jay puts his amazing insights and learning moments from a lifetime behind the lens into a book that communicates the three most important aspects of street photography: light, gesture, and color. Each page unveils something new and challenges you to rethink everything you know about the bigger picture of photography. This isn’t a book about f-stops or ISOs. It’s about seeing. It’s about being surrounded by the ordinary and learning how to find the extraordinary. It’s about training your mind, and your eyes, to see and capture the world in a way that delights, engages, and captivates your viewers, and there is nobody that communicates this, visually or through the written word, like Jay Maisel. Light, Gesture & Color is the seminal work of one of the true photographic geniuses of our time, and it can be your key to opening another level of understanding, appreciation, wonder, and creativity as you learn to express yourself, and your view of the world, through your camera. If you’re ready to break through the barriers that have held your photography back and that have kept you from making the types of images you’ve always dreamed of, and you’re ready to learn what photography is really about, you’re holding the key in your hands at this very moment.
In this volume, Geoffrey Madell develops a revised account of the self, making a compelling case for why the "simple" or "anti-criterial" view of personal identity warrants a robust defense. Madell critiques recent discussions of the self for focusing on features which are common to all selves, and which therefore fail to capture the uniqueness of each self. In establishing his own view of personal identity, Madell proposes (a) that there is always a gap between ‘A is f and g’ and ‘I am f and g’; (b), that a complete description of the world offered without recourse to indexicals will fail to account for the contingent truth that I am one of the persons described; and (c), that an account of conscious perspectives on the world must take into account what it means for an apparently arbitrary one of these perspectives to be mine. Engaging with contemporary positions on the first person, embodiment, psychological continuity, and other ongoing arguments, Madell contends that there can be no such thing as a criterion of personal identity through time, that no bodily or psychological continuity approach to the issue can succeed, and that personal identity through time must be absolute, not a matter of degree. Madell’s view that the nature of the self is substantively different from that of objects in the world will generate significant discussion and debate among philosophers of mind.
Synthesizing complex theories, debates and information on nature this text explores the ways in which nature has been studied, emphasizing the relationships and differences between diverse branches of geography.
