The vital interconnections that rivers share with the land, the sky, and us Rivers are essential to civilization and even life itself, yet how many of us truly understand how they work? Why do rivers run where they do? Where do their waters actually come from? How can the same river flood one year and then dry up the next? Where the River Flows takes you on a majestic journey along the planet's waterways, providing a scientist's reflections on the vital interconnections that rivers share with the land, the sky, and us. Sean Fleming draws on examples ranging from common backyard creeks to powerful and evocative rivers like the Mississippi, Yangtze, Thames, and Congo. Each chapter looks at a particular aspect of rivers through the lens of applied physics, using abundant graphics and intuitive analogies to explore the surprising connections between watershed hydrology and the world around us. Fleming explains how river flows fluctuate like stock markets, what "digital rainbows" can tell us about climate change and its effects on water supply, how building virtual watersheds in silicon may help avoid the predicted water wars of the twenty-first century, and much more. Along the way, you will learn what some of the most exciting ideas in science—such as communications theory, fractals, and even artificial life—reveal about the life of rivers. Where the River Flows offers a new understanding of the profound interrelationships that rivers have with landscapes, ecosystems, and societies, and shows how startling new insights are possible when scientists are willing to think outside the disciplinary box.

Mit großer Spannung wurde sie erwartet, auch von Nicht-Katholiken: Die Umwelt-Enzyklika von Papst Franziskus nimmt die heute entscheidenden Themen in den Blick; es geht um die geht um soziale, ökologische und politische Zusammenhänge. Wohl selten war ein päpstliches Schreiben so aktuell und brisant und vor allem relevant für alle Gesellschaftsschichten und Menschen weltweit. Mit "Laudato si" beweist Franziskus, dass die Kirche nach wie vor eine unverzichtbare Stimme im Diskurs zur Gestaltung der modernen Welt ist. Wer verstehen will, wie Papst und Kirche die großen Herausforderungen unserer Zeit bestehen wollen, kommt an diesem Werk nicht vorbei. Ein Muss für jeden, der an den drängenden Fragen unserer Zeit interessiert ist.

Ehrenfried Pfeiffer was a German scientist, soil scientist, leading advocate of biodynamic agriculture, anthroposophist and disciple of Rudolf Steiner. 'The Earth's Face - Landscape And Its Relation To The Health Of The Soil' reflects Pfeiffer's concern for the different landscapes of the earth, and the effects that industrialisation and mechanisation are having on the environment. He looks at various landscapes, from rural plains, woods and mountains to urban centres and gardens and explains what factors both natural and artificial lead to the degradation of soil fertility.

The Indian National Science Academy was established in January 1935 with the objective of promoting science in India and harnessing scientific knowledge for the cause of humanity and national welfare. In 1968 it was designated as the adhering organisation in India to the International Council for Scientific Union (ICSU) on behalf of the Government of India. Over the years, the Academy has published a number of journals, volumes, biographical memoirs, etc. The year 2009–2010 will be specially celebrated to mark the Platinum Jubilee of the Academy. Many programmes are planned in different centres in India on this occasion. In addition, the Academy has decided to publish a number of special volumes on different s- jects ranging from earth sciences to life sciences. This volume is on Physics and Chemistry of the Earth’s Interior. One of the main objectives of geophysicists is to establish the internal structure of the earth as revealed by seismic tomography. It is also their primary goal to correlate geophy- cal data to reveal thermal and chemical state of the crust, mantle and core of the earth. In - der to interpret seismic velocities and associated density and elastic properties in terms of mineralogical and petrological models of the earth’s interior, thermodynamic and hi- pressure temperature data from mineral physics are essential. With the advent of different types of multi-anvil and laser-heated diamond anvil equipment, it is now possible to simulate conditions prevalent even in the lower mantle and core of the earth.

Alle Welt redet von schwindenden Energieressourcen; dass sich daneben eine ungleich gravierendere Wasserkrise anbahnt, ist bis jetzt kaum ins Bewusstsein gedrungen. Selbst wer umweltbewusst zu Hause Wasser spart, weiss selten, wieviel ”virtuelles Wasser“ er über Nahrung und Kleidung tatsächlich verbraucht: 5.000 Liter Wasser sind nötig, um ein Kilo Reis zu erzeugen, 11.000 Liter für das Rindfleisch eines Hamburgers, unglaubliche 20.000 Liter stecken in 1 kg Kaffeepulver. Kein Wunder, dass sich die Flüsse der Welt in atemberaubendem Tempo leeren, während durch Überregulierung andererseits die Flutgefahr dramatisch steigt. Längst weiss man, dass gigantomanische Bewässerungs- und Staudammprojekte eine enorme ökologische und ökonomische Verschwendung darstellen. Doch schon geht man weltweit dazu über, auch die unterirdischen Wasserreservoirs leer zu pumpen. Ressourcenkriege um Wasser bahnen sich an, denn: Ohne Öl können wir zur Not leben, ohne Wasser sicher nicht. Fred Pearces Berichte lesen sich wie Kriminalgeschichten und geben zugleich einen umfassenden Überblick über die Wasserkrise und ihre Auswirkungen.

The Meaning of Rivers

In the continental United States, rivers serve to connect state to state, interior with exterior, the past to the present, but they also divide places and peoples from one another. These connections and divisions have given rise to a diverse body of literature that explores American nature, ranging from travel accounts of seventeenth-century Puritan colonists to magazine articles by twenty-first-century enthusiasts of extreme sports. Using pivotal American writings to determine both what literature can tell us about rivers and, conversely, how rivers help us think about the nature of literature, The Meaning of Rivers introduces readers to the rich world of flowing water and some of the different ways in which American writers have used rivers to understand the world through which these waters flow. Embracing a hybrid, essayistic form—part literary theory, part cultural history, and part fieldwork—The Meaning of Rivers connects the humanities to other disciplines and scholarly work to the land. Whether developing a theory of palindromes or reading works of American literature as varied as Henry David Thoreau's A Week on the Concord and Merrimack Rivers and James Dickey’s Deliverance, McMillin urges readers toward a transcendental retracing of their own interpretive encounters. The nature of texts and the nature of “nature” require diverse and versatile interpretation; interpretation requires not only depth and concentration but also imaginative thinking, broad-mindedness, and engaged connection-making. By taking us upstream as well as down, McMillin draws attention to the potential of rivers for improving our sense of place and time.

The Natural Law of Cycles assembles scientific work from different disciplines to show how research on angular momentum and rotational symmetry can be used to develop a law of energy cycles as a local and global influence. Angular momentum regulates small-scale rotational cycles such as the swimming of fish in water, the running of animals on land, and the flight of birds in air. Also, it regulates large-scale rotation cycles such as global currents of wind and water. James H. Bunn introduces concepts of symmetry, balance, and angular momentum, showing how together they shape the mobile symmetries of animals. Chapter 1 studies the configurations of animals as they move in a head-first direction. Chapter 2 shows how sea animals follow currents and tides generated by the rotational cycles of the earth. In chapter 3, Bunn explores the biomechanical pace of walking as a partial cycle of rotating limbs. On a large scale, angular momentum governs balanced shifts in plate tectonics. Chapter 4 begins with an examination of rotational wind patterns in terms of the counter-balancing forces of angular momentum. The author shows how these winds augment the flights of birds during migrations. A final chapter centers on the conservation of energy as the most basic principle of science. Bunn argues that in the nineteenth century the unity of nature was seen in the emergent concept of energy, not matter, as the source of power, including the movements of animals and machines. In each chapter Bunn features environmental writers who celebrate mobile symmetries. This book will interest students, naturalists, and advocates of the environmental movement.
