This book covers the major problems of turbulence and turbulent processes, including physical phenomena, their modeling and their simulation. After a general introduction in Chapter 1 illustrating many aspects dealing with turbulent flows, averaged equations and kinetic energy budgets are provided in Chapter 2. The concept of turbulent viscosity as a closure of the Reynolds stress is also introduced. Wall-bounded flows are presented in Chapter 3 and aspects specific to boundary layers and channel or pipe flows are also pointed out. Free shear flows, namely free jets and wakes, are considered in Chapter 4. Chapter 5 deals with vortex dynamics. Homogeneous turbulence, isotropy and dynamics of ...
The Animal Side is a manifesto on the importance of animals for human thought. It attempts to characterize the importance, for human beings, of the fact that animals exist. Adopting a philosophical and poetic approach, the book seeks to show that animals' ways of inhabiting the earth are, for human consciousness, an expansion and an exploration of what philosophers and poets have tried to name by speaking of the Open. Beginning with the story of an encounter with a deer on a road at night, the book proceeds by showing that, beyond the diversity of animal life and the ways animals differ from human beings, there is a "layer of the perceptible" on which we all draw, humans and animals alike, in our own ways. At present, however, this layer itself is at risk. Thus the book can also be read as a defense and illustration of animals' modes of being, and as a plea for their survival.
In all latitudes, writers hold out a mirror, leading the reader to awareness by telling real or imaginary stories about people of good will who try to save what can be saved, and about animals showing humans the way to follow. Such tales argue that, in spite of all destructions and tragedies, if we are just aware of, and connected to, the real world around us, to the blade of grass at our feet and the star above our heads, there is hope in a reconciliation with the Earth. This may start with the emergence, or, rather, the return, of a nonverbal language, restoring the connection between human beings and the nonhuman world, through a form of communication beyond verbalization. Through a journ...
A compelling and innovative reflection on the way photography captures and condenses time Two photographs, connected by a ladder, separated by a century. First, William Henry Fox Talbot photographed a faithfully realistic image of a ladder against a haystack in the English countryside.One hundred years later, an anonymous photographer captured another ladder, “photographed” alongside an incinerated man by the blinding light of the atomic bomb. These two images underpin a poetic and theoretical reflection on the origins of photographic technique, the imaginative power of montage, and the relation of photography to time itself in Jean-Christophe Bailly’s The Instant and Its Shadow, trans...

This is the first book to catalog comparative maps and tableaux that visualize the heights and lengths of the world's mountains and rivers. Produced predominantly in the nineteenth century, these beautifully rendered maps emerged out of the tide of exploration and scientific developments in measuring techniques. Beginning with the work of explorer Alexander von Humboldt, these historic drawings reveal a world of artistic and imaginative difference. Many of them give way—and with visible joy—to the power of fantasy in a mesmerizing array of realistic and imaginary forms. Most of the maps are from the David Rumsey Historical Map Collection at Stanford University.
The sixth ERCOFTAC Workshop on ‘Direct and Large-Eddy Simulation’ (DLES-6) was held at the University of Poitiers from September 12-14, 2005. Following the tradition of previous workshops in the DLES-series, this edition has reflected the state-of-the-art of numerical simulation of transitional and turbulent flows and provided an active forum for discussion of recent developments in simulation techniques and understanding of flow physics.
Are totems merely a thing of the distant past? Or might it be that our sleek new machines are producing totemic forces which we are only beginning to recognize? This book asks to what degree today's media technologies are haunted by a Freudian ghost, functioning as totems or taboos (or both). By isolating five case-studies (rabbits in popular culture, animated creatures that go "off-program," virtual lovers, jealous animal spirit guides, and electronic paradises), Look at the Bunny highlights and explores today's techno-totemic environment. In doing so, it explores how nonhuman avatars are increasingly expected to shepherd us beyond our land-locked identities, into a risky - sometimes ecstatic - relationship with the Other. ,
Since the early 1980s, art photographers from metropolitan France have been training their lenses on ordinary landscapes throughout the country they call home. The Topographic Imaginary is the first book to study this important and flourishing trend. It examines work by artists who meld documentary and creative modes to attune viewers to places that mainstream culture tends to tune out, but which, as Ari J. Blatt argues, are in fact more meaningful than they initially appear. From views of building sites in Paris, peri-urban edgelands, or a tangle of trees in a forest, to those that ponder the play of light and shadow on roadside fields in Normandy or the tacky colors painted on dated villag...
Though sometimes dubbed "the first wildlife photographer," George Shiras is not a prominent name in the history of photography. While his photos were shown at the Paris World Fair of 1900, Shiras--also a lawyer and politician--did not consider himself an artist; his goal was, above all, to document wildlife from the pre-environmental perspective to which he dedicated his life. In 1893, Shiras perfected the procedure of nocturnal flash photography in various regions of the US and Canada. It was in contact with hunters--and also with Native American guides or trappers--that he became initiated in the ways of wildlife, eventually "exchanging the rifle for the camera," as he himself put it. Desp...
