Why is the future so different from the past? Why does the past affect the future and not the other way around? What does quantum mechanics really tell us about the world? In this important and accessible book, Huw Price throws fascinating new light on some of the great mysteries of modern physics, and connects them in a wholly original way. Price begins with the mystery of the arrow of time. Why, for example, does disorder always increase, as required by the second law of thermodynamics? Price shows that, for over a century, most physicists have thought about these problems the wrong way. Misled by the human perspective from within time, which distorts and exaggerates the differences between past and future, they have fallen victim to what Price calls the "double standard fallacy": proposed explanations of the difference between the past and the future turn out to rely on a difference which has been slipped in at the beginning, when the physicists themselves treat the past and future in different ways. To avoid this fallacy, Price argues, we need to overcome our natural tendency to think about the past and the future differently. We need to imagine a point outside time -- an Archimedean "view from nowhen" -- from which to observe time in an unbiased way. Offering a lively criticism of many major modern physicists, including Richard Feynman and Stephen Hawking, Price shows that this fallacy remains common in physics today -- for example, when contemporary cosmologists theorize about the eventual fate of the universe. The "big bang" theory normally assumes that the beginning and end of the universe will be very different. But if we are to avoid the double standard fallacy, we need to consider time symmetrically, and take seriously the possibility that the arrow of time may reverse when the universe recollapses into a "big crunch." Price then turns to the greatest mystery of modern physics, the meaning of quantum theory. He argues that in missing the Archimedean viewpoint, modern physics has missed a radical and attractive solution to many of the apparent paradoxes of quantum physics. Many consequences of quantum theory appear counterintuitive, such as Schrodinger's Cat, whose condition seems undetermined until observed, and Bell's Theorem, which suggests a spooky "nonlocality," where events happening simultaneously in different places seem to affect each other directly. Price shows that these paradoxes can be avoided by allowing that at the quantum level the future does, indeed, affect the past. This demystifies nonlocality, and supports Einstein's unpopular intuition that quantum theory describes an objective world, existing independently of human observers: the Cat is alive or dead, even when nobody looks. So interpreted, Price argues, quantum mechanics is simply the kind of theory we ought to have expected in microphysics -- from the symmetric standpoint. Time's Arrow and Archimedes' Point presents an innovative and controversial view of time and contemporary physics. In this exciting book, Price urges physicists, philosophers, and anyone who has ever pondered the mysteries of time to look at the world from the fresh perspective of Archimedes' Point and gain a deeper understanding of ourselves, the universe around us, and our own place in time.

The purpose of my book, The Tip of the Arrow, A Study in Leadership, is to share with young people of today and tomorrow the story of young people like me at age sixteen as the blueprint of the Selma Student Nonviolent Civil Rights movement, a significant impacting factor in the passage of the 1964 Civil Rights Act and the dominating influence leading to the passage of the 1965 Voting Rights Act. On February 24, 2016, during a ceremony awarding the Congressional Gold Medal at the US Capitol in Washington, DC, I beamed with personal pride upon hearing Speaker Paul Ryan's statement that Congress decided to bestow the award to the foot soldiers because their contribution to our country was so great that they deserved the highest honor in our possession, the Congressional Gold Medal. The Tip of the Arrow is our story.

The American Southwest is the focus for this volume in Noel Justice's series of reference works that survey, describe, and categorize the projectile point and cutting tools used in prehistory by Native American peoples. Written for archaeologists and amateur collectors alike, the book describes over 50 types of stone arrowhead and spear points according to period, culture, and region. With the knowledge of someone trained to fashion projectile points with techniques used by the Indians, Justice describes how the points were made, used, and re-sharpened. His detailed drawings illustrate the way the Indians shaped their tools, what styles were peculiar to which regions, and how the various types can best be identified. There are hundreds of drawings, organized by type cluster and other identifying characteristics. The book also includes distribution maps and color plates that will further aid the researcher or collector in identifying specific periods, cultures, and projectile types.

What is time? The Janus Point offers a ground-breaking solution to one of the greatest mysteries in physics. For over a century, the greatest minds have sought to understand why time seems to flow in one direction, ever forward. In The Janus Point, Julian Barbour offers a radically new answer: it doesn't. At the heart of this book, Barbour provides a new vision of the Big Bang - the Janus Point - from which time flows in two directions, its currents driven by the expansion of the universe and the growth of order in the galaxies, planets and life itself. What emerges is not just a revolutionary new theory of time, but a hopeful argument about the destiny of our universe.

David Knoke and Song Yang′s Social Network Analysis, Third Edition provides a concise introduction to the concepts and tools of social network analysis. The authors convey key material while at the same time minimizing technical complexities. The examples are simple: sets of 5 or 6 entities such as individuals, positions in a hierarchy, political offices, and nation-states, and the relations between them include friendship, communication, supervision, donations, and trade. The new edition reflects developments and changes in practice over the past decade. The authors also describe important recent developments in network analysis, especially in the fifth chapter. Exponential random graph models (ERGMs) are a prime example: when the second edition was published, P* models were the recommended approach for this, but they have been replaced by ERGMs. Finally, throughout the volume, the authors comment on the challenges and opportunities offered by internet and social media data.

: (1) Prosthodontics enjoys the honor of being the largest and probably the oldest discipline in the whole of dentistry. The technical importance of the subject may be understood by the fact that it is the only subject in the dental professional curriculum that is taught at the undergraduate (BDS) level from I year to the final year of the curriculum with maximum number of teaching hours devoted to it.The teeth are being extracted and being replaced by artificial teeth since a very long time. This may be some or all of the teeth. The complete dentures form one of the most important fields of Prosthodontics as this deals with majorly the restoration of the function of the patient.Thus a successful Prosthodontic treatment is a boon especially to the elderly section of our society which usually gets cutoff from the main stream of the social structure owing to their physical weakness and mental frustration which creates a vicious circle in the minds of these gentle people. Once restored to proper health and good oral functions, a tremendous boost of confidence is appreciated in such patients as they begin to re-enjoy their life and in a sense begin to re-live it. It basically covers all of the associated aspects of complete dentures also giving an insight into the Prosthodontic viewpoint of the maxillofacial prosthetics and the implant dentistry, hence encompassing the major part of complete dentures and to that the latest trends.

First published in 1992 and now updated with a new preface by the author and a foreword by Thomas R. Hester, "The Caddo Nation" investigates the early contacts between the Caddoan peoples of the present-day Texas, Louisiana, Oklahoma, and Arkansas region and Europeans, including the Spanish, French, and some Euro-Americans. Perttula's study explores Caddoan cultural change from the perspectives of both archaeological data and historical, ethnographic, and archival records. The work focuses on changes from A.D. 1520 to ca. A.D. 1800 and challenges many long-standing assumptions about the nature of these changes.
