Book Description
The sun, moon, stars, and planets have been a source of wonder for as long as humans have lived on earth. In this highly visual guide to observing the sky with the naked eye, kids aged 9–14 will delve into the science behind what they see. This captivating book offers a tour of our solar system and deep space, explaining how objects like Earth’s moon were formed and introducing the “why” behind phenomena such as eclipses, northern lights, and meteor showers. Sky gazers will learn how to find and observe planets — no binoculars or telescopes required — and star charts will show them how to spot constellations through the seasons and in both hemispheres. Activities include tracking the cycles of the sun and moon and observing the sky during daylight hours or on a cloudy night. Includes profiles of professional astronomers and sidebars on space technology and current issues, such as light pollution.

Book Description
This book is a gentle introduction to dominance-based query processing techniques and their applications. The book aims to present fundamental as well as some advanced issues in the area in a precise, but easy-to-follow, manner. Dominance is an intuitive concept that can be used in many different ways in diverse application domains. The concept of dominance is based on the values of the attributes of each object. An object dominates another object if is better than . This goodness criterion may differ from one user to another. However, all decisions boil down to the minimization or maximization of attribute values. In this book, we will explore algorithms and applications related to dominance-based query processing. The concept of dominance has a long history in finance and multi-criteria optimization. However, the introduction of the concept to the database community in 2001 inspired many researchers to contribute to the area. Therefore, many algorithmic techniques have been proposed for the efficient processing of dominance-based queries, such as skyline queries, -dominant queries, and top- dominating queries, just to name a few.

Book Description
The complete four-book series! Enter the world of the Entire in this first book of the celebrated four-volume epic. In a land-locked galaxy that tunnels through our own, the Entire gathers both human and alien beings under a sky of fire, called the bright. A land of wonders, the Entire is sustained by monumental storm walls and a never-ending river. Over all, the elegant and cruel Tarig rule supreme. Into this rich milieu is thrust Titus Quinn, former star pilot, bereft of his beloved wife and daughter who are assumed dead by everyone on earth except Quinn. Believing them trapped in a parallel universe—one where he himself may have been imprisoned—he returns to the Entire to free them. Thus begins a tale of high adventure and vast concept, replete with alien cultures, an exotic bureaucracy, and a man with nothing left to lose. He may not find what he seeks, but he’ll be offered a view of the multiverse, the power of princes, an unthinkable revenge—and unexpectedly, love. "A riveting launch." ––Publisher's Weekly starred review [A] fascinating and gratifying feat of world building. . . . promises to be a grand epic, indeed.”—Booklist “[A] star-maker, a magnificent book that should establish its author's reputation as among the very best in the field today.”—SFSite.com

Book Description
NEW YORK TIMES BESTSELLER “This is history at its most immediate and moving…A marvelous and memorable book.” —Jon Meacham “Remarkable…A priceless civic gift…On page after page, a reader will encounter words that startle, or make him angry, or heartbroken.” —The Wall Street Journal “Had me turning each page with my heart in my throat…There’s been a lot written about 9/11, but nothing like this. I urge you to read it.” —Katie Couric The first comprehensive oral history of September 11, 2001—a panoramic narrative woven from voices on the front lines of an unprecedented national trauma. Over the past eighteen years, monumental literature has been published about 9/11, from Lawrence Wright’s The Looming Tower to The 9/11 Commission Report. But one perspective has been missing up to this point—a 360-degree account of the day told through firsthand. Now, in The Only Plane in the Sky, Garrett Graff tells the story of the day as it was lived—in the words of those who lived it. Drawing on never-before-published transcripts, declassified documents, original interviews, and oral histories from nearly five hundred government officials, first responders, witnesses, survivors, friends, and family members, he paints the most vivid and human portrait of the September 11 attacks yet. Beginning in the predawn hours of airports in the Northeast, we meet the ticket agents who unknowingly usher terrorists onto their flights, and the flight attendants inside the hijacked planes. In New York, first responders confront a scene of unimaginable horror at the Twin Towers. From a secret bunker under the White House, officials watch for incoming planes on radar. Aboard unarmed fighter jets in the air, pilots make a pact to fly into a hijacked airliner if necessary to bring it down. In the skies above Pennsylvania, civilians aboard United 93 make the ultimate sacrifice in their place. Then, as the day moves forward and flights are grounded nationwide, Air Force One circles the country alone, its passengers isolated and afraid. More than simply a collection of eyewitness testimonies, The Only Plane in the Sky is the historic narrative of how ordinary people grappled with extraordinary events in real time: the father and son caught on different ends of the impact zone; the firefighter searching for his wife who works at the World Trade Center; the operator of in-flight telephone calls who promises to share a passenger’s last words with his family; the beloved FDNY chaplain who bravely performs last rites for the dying, losing his own life when the Towers collapse; and the generals at the Pentagon who break down and weep when they are barred from trying to rescue their colleagues. At once a powerful tribute to the courage of everyday Americans and an essential addition to the literature of 9/11, The Only Plane in the Sky weaves together the unforgettable personal experiences of the men and women who found themselves caught at the center of an unprecedented human drama. The result is a unique, profound, and searing exploration of humanity on a day that changed the course of history, and all of our lives.

Book Description
Why live under a pagan sky? For thousands of years, humankind has dwelled under a dome of stars that have been grouped and identified according to ancient superstitions. Today, the official star constellations pay homage to the pagan gods and goddesses of a dark and chaotic world, a world before Christ, and yet these are the constellations that scouting groups and school children all around the world have been encouraged to learn for hundreds of years. Now, for the first time, the sky has been mapped in accordance with easy-to-find star patterns that tell the stories of the Christian faith. No telescope required. No sophisticated instruments needed. After presenting a few simple but very effective techniques for finding your way through the sky at night, the author takes you on a tour of the Christian constellations. Using new constellations inspired by stories from the Bible, you will be able to locate stars, planets, star clusters, and galaxies during any time of the night and at any time of the year. If you have ever wanted to know more about God's grandest creation but have never felt comfortable learning about ancient pagan idols, then this book will provide you with a healthy fresh start.

Book Description
Recently, there has been a surge of interest in the lexicon. The demand for a fuller and more adequate understanding of lexical meaning required by developments in computational linguistics, artificial intelligence, and cognitive science has stimulated a refocused interest in linguistics, psychology, and philosophy. Different disciplines have studied lexical structure from their own vantage points, and because scholars have only intermittently communicated across disciplines, there has been little recognition that there is a common subject matter. The conference on which this volume is based brought together interested thinkers across the disciplines of linguistics, philosophy, psychology, and computer science to exchange ideas, discuss a range of questions and approaches to the topic, consider alternative research strategies and methodologies, and formulate interdisciplinary hypotheses concerning lexical organization. The essay subjects discussed include: * alternative and complementary conceptions of the structure of the lexicon, * the nature of semantic relations and of polysemy, * the relation between meanings, concepts, and lexical organization, * critiques of truth-semantics and referential theories of meaning, * computational accounts of lexical information and structure, and * the advantages of thinking of the lexicon as ordered.
