Microcontinuum Field Theories constitutes an extension of classical field theories - of elastic solids, viscous fluids, electromagnetism, and the like - to microscopic length and time scales. Material bodies are viewed as collections of a large number of deformable particles (sub-continua), suitable for modeling blood, porous media, polymers, liquid crystals, slurries, and composite materials. This volume extends and applies the ideas developed in the first volume, Microcontinuum Field Theories: Foundations and Solids, to liquid crystals, biological fluids, and other microstretch and micomorphic fluids. The theory makes it possible to discuss properties of such materials that are beyond the scope of classical field theories and may provide a basis for the resolution of some outstanding problems, such as turbulence.
Susan Gordon's extraordinary language conveys us through death to dissolution and transfiguration, as she bears careful, caring witness to the body of a belly-shot doe day after day, week after week, month after month, through all seasons of the weather and the soul. Time and again precise description breaks open into transcendent vision; beauty entwines with horror, both driving towards the "unraveling / of what comes / after everything has been undone." This is a masterpiece, a poem I will cherish and revisit for many years.

This book describes the picture of reality given by Newton, and the development of the later picture of reality given by field theory. In telling this story, the author explains what problem each scientist faced, and how the process of solving them led to new discoveries. By this method he gives unique insight into the understanding of Einstein's special theory of relativity, as he explains exactly what problems led to the invention of the theory, and exactly where Einstein's solution differed from his predecessors'. A similar analysis is given of the discoveries of Faraday, Maxwell, Hertz and Lorentz. The problem-oriented approach of the book, originally published in 1974, enables the reader to share in the original creative process, and in the excitement of the discoveries. It puts physics problems into new perspective and discusses the philosophical implications of the history - an illuminating account of a great episode in the history of thought.

The colorful boyhood of a popular author comes to life in this personal account
Imagine learning from a nosy classmate that your mother is having yet another baby. To Ralph's classmates, news of one more Fletcher baby is just "scuttlebutt." But for Ralph, the oldest of nine, being part of a large family means more kids to join in the fun--from making tripods in the woods and "snicking" up the rug to raising chicks and even discovering a meteor (well, maybe). It doesn't feel like there's life beyond Marshfield, Massachusetts. Then one day Dad's new job moves the family to Chicago, and there's so much Ralph has to leave behind. In this humorous and captivating memoir, Ralph Fletcher traces the roots of his storytelling.
