Ranging from ancient times to twentieth-century theories of time and space, looks at how exploring the circle has lead to increased knowledge about the physical universe.

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.

Francis Bacon introduced his contemporaries to a new way of investigating nature. He called it "natural and experimental history." Despite its rather traditional name, Bacon's natural and experimental history was a new discipline: it comprised new ideas, new practices and new models of collaborative research. This new discipline was, in many ways, a surprisingly successful project. It provided early modern naturalists with tools, methods and models for both investigating nature and writing about their subject. It also offered a set of norms and values for guiding research. And yet, this new discipline was not a science of nature -- it was more like an art. This book aims to trace the emergence, evolution and reception of Francis Bacon's art of experimental natural history.

Out of the diverse traditions of medical humanism, classical philology, and natural philosophy, Renaissance naturalists created a new science devoted to discovering and describing plants and animals. Drawing on published natural histories, manuscript correspondence, garden plans, travelogues, watercolors, and drawings, The Science of Describing reconstructs the evolution of this discipline of description through four generations of naturalists. In the late fifteenth and early sixteenth centuries, naturalists focused on understanding ancient and medieval descriptions of the natural world, but by the mid-sixteenth century naturalists turned toward distinguishing and cataloguing new plant and animal species. To do so, they developed new techniques of observing and recording, created botanical gardens and herbaria, and exchanged correspondence and specimens within an international community. By the early seventeenth century, naturalists began the daunting task of sorting through the wealth of information they had accumulated, putting a new emphasis on taxonomy and classification. Illustrated with woodcuts, engravings, and photographs, The Science of Describing is the first broad interpretation of Renaissance natural history in more than a generation and will appeal widely to an interdisciplinary audience.

What these extracts are, first and foremost, are stories of discovery. The Art of Science is not necessarily a book about great scientific theories, complicated equations, or grand old men (or women) in their laboratories; instead, it's about the places we draw our inspiration from; it's about daily routines and sudden flashes of insight; about dedication, and - sometimes - desperation; and the small moments, questions, quests, clashes, doubts and delights that make us human. From Galileo to Lewis Carroll, from Humphry Davy to Charles Darwin, from Marie Curie to Stephen Jay Gould, from rust to snowflakes, from the first use of the word "scientist" to the first computer, from why the sea is salty to Newtonian physics for women, The Art of Science is a book about people, rather than scientists per se, and as such, it's a book about politics, passion and poetry. Above all, it's a book about the good that science can - and does - do.
