The evaluation of Coulombic or gravitational interactions in large ensembles of particles is an integral part of the numerical simulation of a large number of physical processes. Examples include celestial mechanics, plasma physics, the vortex method in fluid dynamics, molecular dynamics, molecular dynamics, and the solution of the Laplace equation via potential theory. A numerical model follows the trajectories of a number of particles moving in accordance with Newton's second law of motion in a field generated by the whole ensemble. In many situations, in order to be of physical interest, the simulation has to involve thousands of particles (or more), and the fields have to be evaluated for a large number of configurations. Unfortunately, an amount of work of the order O N-sg has traditionally been required to evaluate all pairwise interactions in a system of N particles, unless some approximation or truncation method is used. Large scale simulations have been extremely expensive in some cases, and prohibitive in others. An algorithm is presented for the rapid evaluation of the potential and force fields in large scale systems of particles. To evaluate all pairwise Coulombic interactions of N particles to within round off error, the algorithm requires an amount of work proportional to N, and this estimate does not depend on the statistics of the distribution. Both two and three dimensional versions of the algorithm have been constructed. Applications to several problems in physics, chemistry, biology, and numerical complex analysis are discussed.
A groundbreaking study of the interaction of poetry, performance, and the built environment in ancient Greece. Winner of the PROSE Award for Best Book in Classics by the Association of American Publishers In this volume, Richard Neer and Leslie Kurke develop a new, integrated approach to classical Greece: a "lyric archaeology" that combines literary and art-historical analysis with archaeological and epigraphic materials. At the heart of the book is the great poet Pindar of Thebes, best known for his magnificent odes in honor of victors at the Olympic Games and other competitions. Unlike the quintessentially personal genre of modern lyric, these poems were destined for public performance by choruses of dancing men. Neer and Kurke go further to show that they were also site-specific: as the dancers moved through the space of a city or a sanctuary, their song would refer to local monuments and landmarks. Part of Pindar's brief, they argue, was to weave words and bodies into elaborate tapestries of myth and geography and, in so doing, to re-imagine the very fabric of the city-state. Pindar's poems, in short, were tools for making sense of space. Recent scholarship has tended to isolate poetry, art, and archaeology. But Neer and Kurke show that these distinctions are artificial. Poems, statues, bronzes, tombs, boundary stones, roadways, beacons, and buildings worked together as a "suite" of technologies for organizing landscapes, cityscapes, and territories. Studying these technologies in tandem reveals the procedures and criteria by which the Greeks understood relations of nearness and distance, "here" and "there"—and how these ways of inhabiting space were essentially political. Rooted in close readings of individual poems, buildings, and works of art, Pindar, Song, and Space ranges from Athens to Libya, Sicily to Rhodes, to provide a revelatory new understanding of the world the Greeks built—and a new model for studying the ancient world.
Amphetamines have had a relatively short, though chequered history. In this book, a leading authority on psychoactive drugs explores the uses and abuses of amphetamines. Eschewing dogma, Iversen presents a fascinating and accessible exposé of recreational and medical amphetamine use.
The text ranges from drugs that affect the mood and behavior to hypnotics, narcotics, anticonvulsants, and analgesics, as well as a variety of drugs that affect the autonomic nervous system and psychoactive drugs used for non-medical reasons - nicotine, alcohol, opiates, psychostimulants and cannabis."--BOOK JACKET.
Reprint, 2013, with minor corrections, of the edition published in 1991. The corrections constitute revisions of the translations of some of the Greek text; but these do not substantially change the argument of the book.
The twentieth century saw a remarkable upsurge of research on drugs, with major advances in the treatment of bacterial and viral infections, heart disease, stomach ulcers, cancer, and metal illnesses. These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction, in its second edition, gives a non-technical account of how drugs work in the body. Reviewing both legal (alcohol, nicotine, and caffeine) and illegal drugs, Les Iversen discusses why some are addictive, and whether drug laws need reform. ABOUT THE SERIES The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

ABOUT THE BOOK Who is Natalie Wood? On Sunday, November 29, 1981, the world woke to the news that the talented and well-loved movie star Natalie Wood was dead. She was only 43 years old. But as details of her death became known, the loss became both a tragedy and a mystery. How was it possible that she would die from the one thing that terrified her most: drowning in dark water? For many, it was inconceivable unless something more sinister occurred. Officially, the cause of death was an accident. Although the specifics are unknown, speculation by the authorities and by Robert Wagner, her husband who was on the boat with her at the time, is that she attempted to retie the dinghy that was thumping against the boat and fell in the water. Because Wagner was in a heated argument with their guest, actor Christopher Walken, he didn’t hear her fall or cry for help. In fact, some think she may have hit her head when she fell and was unable to call for help. Regardless, the heavy coat she was wearing would have hindered her attempt to save herself. Thirty years later, the mystery surrounding her death continues. In November 2011, the investigation was reopened based on “new” information, but quickly closed again with the same finding. What’s unfortunate is that Natalie Wood’s death has overshadowed the career of a talented actress. She was a celebrity throughout her career, making the transition from child star, to teen phenom and acclaimed adult actress. She starred in over 56 films, most of which were made when she was a child. She had earned three Oscar nominations by the time she was 25 years old. Her private life was equally as interesting. She was married three times, twice to actor Robert Wagner in what was considered the big Hollywood romance of the time. When she wasn’t married, she was connected romantically to many of the leading actors of her time including James Dean, Warren Beatty, and Elvis Presley. As glamorous as her life appeared, Natalie struggled with depression and insecurity, stemming from a domineering mother and an alcoholic father. Her mother, Mud was a classic showbiz mother who controlled Natalie’s career, including what pictures she’d do and firing agents when she didn’t feel they were doing their job. But Mud’s behavior went well-beyond directing Natalie’s career. She controlled everything and wasn’t opposed to using emotional and psychological manipulation to keep Natalie close. For example, she told Natalie that serial killers stabbed children in the back if they sat too close to the screen in movie theaters. As a result, Natalie was afraid to view movies anywhere but at the studio. Later while watching Natalie’s daughter, Natasha, Mud changed the locks on the doors of the house and told Natasha that her mother and stepfather, Robert Wagner, were dangerous. Mud supposedly also predicted that Natalie would die in dark water, which likely reinforced her fear. This behavior led to resentment by Natalie towards her mother. At the same time, she often felt guilty for not allowing her mother more access to her. Well-liked by her peers, close friends reported Natalie could have a dark side as well, particularly if she was drinking, according to several biographers. At 26 years old, she attempted suicide and semi-retired from her acting career. Even so, she continued to make acclaimed and though provoking films such as Inside Daisy Clover, This Property is Condemned and Bob & Carol & Ted & Alice. EXCERPT FROM THE BOOK Natalie started work on Brainstorm, co-starring Christopher Walken and because of his show, Hart To Hart, Wagner was not able to accompany her to Raleigh N.C. for the shoot. He made a weekend visit and became concerned about a possible affair between her and Walken.... ...buy the book to continue reading!
