Book Description
A title that sounds like poetry, and a subtitle that seems to contradict the title! But the subtitle is right, and originally it was just the title. A strange subtitle, isn’t it? Preface to a Science of Mathematical Education. All sciences – in their prenatal stage – have known this kind of literature: only the term used was not ‘Preface’, but, for instance, ‘Prolegomena’, which * means the same though it sounds less provisional. In fact such works were thicker than the present one, by up to ten times. There is much more that can be said about a science before it comes into being than after; with the first results comes modesty. This is the preface to a book that will never be written: not by me, nor by anybody else. Once a science of mathematical education exists, it will get the preface it deserves. Nevertheless this preface – or what for honesty’s sake I have labelled so – must fulfil a function: the function of accelerating the birth of a science of mathematical education, which is seriously impeded by the unfounded view that such already exists. Against this view I have to argue: it rests on a wrong estimation – both over and under estimation at the same time – of what is to be considered as science.

Book Description
“A hopeful and expansive book for the gardener who sees a field as a canvas.” —Publishers Weekly James Hitchmough is well-regarded in the design world for his exuberant, colorful, and flower-filled meadows. His signature style can be seen in prominent places like London’s Olympic Park and the Botanic Garden at the University of Oxford. Using a distinct technique of sowing meadows from seed, he creates plant communities that mimic the dramatic beauty of natural meadows and offer a succession of blooms over many months—a technique that can be adapted to work in both large-scale public gardens and smaller residential gardens. Sowing Beauty shows you how to recreate Hitchmough’s masterful, romantic style. You'll will learn how to design and sow seed mixes that include a range of plants, both native and exotic, and how to maintain the sown spaces over time. Color photographs show not only the gorgeous finished gardens, but also all the steps along the way.

In A Way to Garden, Roach imparts decades of garden wisdom on seasonal gardening, ornamental plants, vegetable gardening, design, gardening for wildlife, organic practices, and much more. She also challenges gardeners to think beyond their garden borders and to consider the ways gardening can enrich the world.

Book Description
Wild Suburbia guides us through the process of transforming a traditional, high water-use yard into a peaceful habitat garden abounding with native plants. Author Barbara Eisenstein emphasizes that gardening is a rewarding activity rather than a finished product, from removing lawns and getting in touch with a yard's climate to choosing plants and helping them thrive. Supplementing her advice with personal stories from her decades of experience working with native plants, Eisenstein illuminates the joys of tending a native garden--and assures us that any challenges, from managing pests to disapproving neighbors, should never sap the enjoyment out of a pleasurable and fulfilling hobby. For plant lovers curious about their own ecosystems, Wild Suburbia offers a style of gardening that nurtures biodiversity, deepens connection to place, and encourages new and seasoned gardeners alike to experiment and have fun.

Book Description
Crop Resources contains papers that were originally presented as a symposium on Crop Resources at the 17th Annual Meeting of the Society for Economic Botany in Urbana, Illinois, 13-17 June 1976. The volume attempts to evaluate (a) the possible nonfood uses of cultivated plants; (b) the extent to which new and additional food resources may become available; (c) the prospects of several specialized uses of plants such as drugs, insecticides, rubber, and condiments; and (d) the origin of four major crops of the American Midwest and prospects for their future development. The discussions include the possibilities of developing new crops from the view of a chemist; the use of currently cultivated oil-seed crops for industrial purposes; the industrial uses of carbohydrates, principally starch and cellulose; the uses of plant materials as medicines; the successes and shortcomings of the Green Revolution; and the uses of plant materials for insecticides. This book should be of interest to anyone with a concern for natural resources, both renewable and nonrenewable. It should be of particular interest to agronomists, horticulturalists, chemists, chemical engineers, botanists, biologists, pharmacognosists, and anthropologists.
