Dark Object

The facts confirm the UFO crash happened. Officials deny it. What don’t they want us to know? In 1965 a massive wave of UFO sightings occurs worldwide. In 1967 residents of Shag Harbor, Canada, witness a huge UFO crash into the bay. Three Royal Canadian Mounties watch it float before sinking. Navy divers mount an extensive search. Now officials say nothing ever happened. Why? Researchers Don Ledger and Chris Styles—Styles himself an eyewitness to the Shag Harbor crash—have tackled one of the best documented and most top-secret incidents in the annals of UFO sightings. What they have found out will astound—and outrage—readers. From mysterious surveillance twenty-five years after the crash to the sudden disappearance of written records, someone wanted the investigation stopped. But Ledger and Styles now file their stunning report—and reach a chilling conclusion about the Dark Object, what really happened, and what remains hidden today. . . .

The Allure of Things: Process and Object in Contemporary Philosophy contests the view that metaphysics is something to be overcome. By focusing on process and object oriented ontology (OOO) and rejecting the privileging of human existence over the existence of non-human objects, this collection explores philosophy's concern with things themselves. Interest in Latour, Stengers, Whitehead, Harman and Meillassoux has prompted a resurgence of ontological questions outside the traditional subject-object framework of modern critical thought. This new collection consequently proposes a pragmatic and pluralist approach to 'modes of existence'. Drawing together an international range of leading scholars, The Allure of Things fully covers the similarities between OOO and process philosophy, and is an essential addition to the literature on metaphysics.

Intended for advanced undergraduates and beginning graduate students, this text is based on the highly successful course given by Walter Greiner at the University of Frankfurt, Germany. The two volumes on classical mechanics provide not only a complete survey of the topic but also an enormous number of worked examples and problems to show students clearly how to apply the abstract principles to realistic problems.

The contributors bring a wide range of methodologies to bear on the common problem of image-based object recognition. These interconnected essays on three-dimensional visual object recognition present cutting-edge research by some of the most creative neuroscientific, cognitive, and computational scientists in the field. Cassandra Moore and Patrick Cavanagh take a classic demonstration, the perception of "two-tone" images, and turn it into a method for understanding the nature of object representations in terms of surfaces and the interaction between bottom-up and top-down processes. Michael J. Tarr and Isabel Gauthier use computer graphics to study whether viewpoint-dependent recognition mechanisms can generalize between exemplars of perceptually defined classes. Melvyn A. Goodale and G. Keith Humphrey use innovative psychophysical techniques to investigate dissociable aspects of visual and spatial processing in brain-injured subjects. D.I. Perrett, M.W. Oram, and E. Ashbridge combine neurophysiological single-cell data from monkeys with computational analyses for a new way of thinking about the mechanisms that mediate viewpoint-dependent object recognition and mental rotation. Shimon Ullman also addresses possible mechanisms to account for viewpoint-dependent behavior, but from the perspective of machine vision. Finally, Philippe G. Schyns synthesizes work from many areas, to provide a coherent account of how stimulus class and recognition task interact. The contributors bring a wide range of methodologies to bear on the common problem of image-based object recognition.

The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
