This groundbreaking classic is now available in a special anniversary edition with bonus content. Winner of the Newbery Medal as well as the National Book Award, HOLES is a New York Times bestseller and one of the strongest-selling middle-grade books to ever hit shelves! Stanley Yelnats is under a curse. A curse that began with his no-good-dirty-rotten-pig-stealing-great-great-grandfather and has since followed generations of Yelnatses. Now Stanley has been unjustly sent to a boys' detention center, Camp Green Lake, where the boys build character by spending all day, every day digging holes exactly five feet wide and five feet deep. There is no lake at Camp Green Lake. But there are an awful lot of holes. It doesn't take long for Stanley to realize there's more than character improvement going on at Camp Green Lake. The boys are digging holes because the warden is looking for something. But what could be buried under a dried-up lake? Stanley tries to dig up the truth in this inventive and darkly humorous tale of crime and punishment —and redemption. Special anniversary edition bonus content includes: A New Note From the Author!; "Ten Things You May Not Know About HOLES" by Louis Sachar; and more!
Black Holes by Kip S. Thorne,Kirk S. Thorne,Richard H. Price,Douglas A. MacDonald Pdf
A pedagogical introduction to the physics of black holes. The membrane paradigm represents the four-dimensional spacetime of the black hole's "event horizon" as a two-dimensional membrane in three-dimensional space, allowing the reader to understand and compute the behavior of black holes in complex astrophysical environments.
Black Holes by Derek J. Raine,Edwin George Thomas Pdf
This introduction to the fascinating subject of black holes fills a significant gap in the literature which exists between popular, non-mathematical expositions and advanced textbooks at the research level. It is designed for advanced undergraduates and first year postgraduates as a useful stepping-stone to the advanced literature. The book provides an accessible introduction to the exact solutions of Einstein's vacuum field equations describing spherical and axisymmetric (rotating) black holes. The geometry and physical properties of these spacetimes are explored through the motion of particles and light. The use of different coordinate systems, maximal extensions and Penrose diagrams is explained. The association of the surface area of a black hole with its entropy is discussed and it is shown that with the introduction of quantum mechanics black holes cease to be black and can radiate. This result allows black holes to satisfy the laws of thermodynamics and thus be consistent with the rest of physics. In this new edition the problems in each chapter have been revised and solutions are provided. The text has been expanded to include new material on wormholes and clarify various other issues.

Black Holes: Theory and Observation by Friedrich W. Hehl,Claus Kiefer,Ralph J.K. Metzler Pdf
This book addresses graduate students in the first place and is meant as a modern compendium to the existing texts on black hole astrophysics. The authors present in pedagogically written articles our present knowledge on black holes covering mathematical models including numerical aspects and physics and astronomical observations as well. In addition, in their write-up of a panel discussion the participants of the school address the existence of black holes consenting that it has by now been verified with certainty.

Physics of Black Holes by I. Novikov,V. Frolov Pdf
One of the most exciting predictions of Einstein's theory of gravitationisthat there may exist 'black holes': putative objects whose gravitational fields are so strong that no physical bodies and signals can break free of their pull and escape. Even though a completely reliable discovery of a black hole has not yet been made, several objects among those scrutinized by astrophysicists will very likely be conformed as black holes. The proof that they do exist, and an analysis of their properties, would have a significance going far beyond astrophysics. Indeed, what is involved is not just the discovery of yet another, even if extremely remarkable, astrophysical object, but a test of the correctness of our understanding the properties of space and time in extremely strong gravitational fields. Theoretical research into the properties of black holes and into the possible corollaries of the hypothesis that they exist, has been carried out with special vigor since the beginning of the 1970s. In addition to those specific features of black holes that are important for the interpretation of their possible astrophysical manifestations, the theory has revealed a nurober of unexpected characteristics of physical interactions involving black holes. By now, a fairly detailed understanding has been achieved of the properties of the black holes, their possible astrophysical manifestations, and the specifics of the various physical processes involved. Furthermore, profound links were found between black-hole theory and such seemingly very distant fields as thermodynamics, information theory, and quantum theory.
This book provides an accessible introduction to the fascinating and topical subject of black holes. It bridges the gap between popular non-mathematical expositions and advanced research texts, using simple undergraduate level calculations and the most basic knowledge of relativity to explain current research. This means the theory can be understood by a wide audience of physicists, including those who are not necessarily interested in learning higher-level mathematical techniques. The third edition links more of the current research trends to fundamental aspects of the physics of black holes. Additionally: It provides an accessible introduction to the two most useful exact solutions of Einstein's vacuum field equations describing black holes, using only basic tensor calculusExplores the geometry and physical properties of these spacetimes through the motion of particles and lightExplains the use of different coordinate systems, maximal extensions and Penrose diagramsDiscusses the association of the surface area of a black hole with its entropy and shows that, with the introduction of quantum mechanics, black holes cease to be black and can radiate. This allows black holes to satisfy the laws of thermodynamics and thus be consistent with the rest of physicsIncludes over 100 problems and solutions This new edition introduces a chapter dedicated to a selection of recent results. Existing chapters have been updated and new explanatory material has been added to aid in the understanding of the physics. This book is recommended reading for advanced undergraduate students and first-year postgraduates who will find it a useful stepping-stone to the advanced literature.

From the detective who helped catch the Golden State Killer, a memoir about investigating America's toughest cold cases, and the rewards - and toll - of a life spent solving crime.For a decade, from 1973, The Golden State Killer stalked and murdered Californians in the dead of night, leaving entire communities afraid to turn off the lights. Then he vanished, and the case remained unsolved.In 1994, when cold-case investigator Paul Holes came across the old file, he swore he would unmask GSK and finally give these families closure. Twenty-four years later, Holes fulfilled that promise, identifying 73-year-old Joseph J. DeAngelo. Headlines blasted around the world: one of America's most prolific serial killers had been caught.That case launched Paul's career into the stratosphere, turning him into an icon in the true-crime world. But while many know the story of the capture of GSK, until now, no one has truly known the man behind it all.In UNMASKED, Paul takes us through his memories of a storied career and provides an insider account of some of the most notorious cases in contemporary American history, including Laci Peterson's murder and Jaycee Dugard's kidnapping. But this is also a revelatory profile of a complex man and what makes him tick: the drive to find closure for victims and their loved ones; the inability to walk away from a challenge - even at the expense of his own happiness. This is a story about the gritty truth of crime solving when there are no 'case closed' headlines. It is the story of a man and his commitment to his cases, and to the people who might have otherwise been forgotten.
