Download or read book Bombarded Britain A Search For British Impact Structures written by Richard Stratford and published by World Scientific. This book was released on 2004-07-26 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a search for geological evidence of meteorite impact structures in Britain. The statistics of impact structures indicate that Britain should have Phanerozoic impact structures up to tens of kilometres in diameter. A constant theme is the importance of atmospheric break-up of small asteroids and comets. These fragmenting bodies produce anomalously shallow craters with low rims and central peaks; three British structures of this type are identified.Analysis of fireball statistics implies that damaging fireball explosions occur over the British Isles on a time-scale of decades. On a time-scale of millennia, however, more damage is done by Atlantic impact tsunami.

Download or read book The Tungus Event Or the Great Siberian Meteorite written by John Engledew and published by Algora Publishing. This book was released on 2010-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This popular science book shares the fascination of the Tungus Event, a major mystery of the 20th century, in a factual and informed way. It provides "on-the-ground" descriptions of the site and explains the findings and the puzzlement of international scientists who have investigated it over the decades. After a brief and readable overview of comets, meteors, the sun and the solar system, the author ponders the range of possible explanations for the "great Siberian meteorite." The research is up to date, factual and scientific. While making no absurd claims to solving the puzzle, the author studies some intriguing clues in NASA's orbit diagrams for Comet Encke, and he is bold in discussing the possible causes of what was the greatest natural explosion in recorded history. As he points out, [Hypotheses] include rogue asteroids, mini black holes and even alien intervention....These explanations are not entirely equal to the facts. In the unique case of the Tunguska event, there was wholesale destruction to the mighty taiga woodlands but none of the debris that one would expect should exist from the body itself. Evidence like a strewn field of meteorite debris or meteoric dust on the trees and ground were never found, nor were any craters, in the area beneath the site of the fireball nor anywhere along the path it took. There are no craters because the Tunguska Cosmic Body (TCB) did not hit the ground. Atmospheric anomalies prior to the dramatic appearance of the fiery body puzzlingly occurred for several days, adding to the enigma. There are just a handful of English-language books on this subject. The most recent, The Tunguska Mystery, by the Russian Rubstov (Astronomers Universe, Springer Science 2009) is authoritative but highly technical and hard going for the general reader. Mr. Engledew instead tells the story in a balanced and engaging style.

Download or read book Law and Regulation of Commercial Mining of Minerals in Outer Space written by Ricky Lee and published by Springer Science & Business Media. This book was released on 2012-03-05 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph addresses the legal and policy issues relating to the commercial exploitation of natural resources in outer space. It begins by establishing the economic necessity and technical feasibility of space mining today, an estimate of the financial commitments required, followed by a risk analysis of a commercial mining venture in space, identifying the economic and legal risks. This leads to the recognition that the legal risks must be minimised to enable such projects to be financed. This is followed by a discussion of the principles of international space law, particularly dealing with state responsibility and international liability, as well as some of the issues arising from space mining activities. Much detail is devoted to the analysis of the content of the common heritage of mankind doctrine. The monograph then attempts to balance such interests in creating a legal and policy compromise to create a new regulatory regime.

Download or read book Imagining the End written by James Craig Holte and published by Bloomsbury Publishing USA. This book was released on 2019-11-11 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Imagining the End provides students and general readers with contextualized examples of how the apocalypse has been imagined across all mediums of American popular culture. Detailed entries analyze the development, influence, and enjoyment of end-times narratives. Imagining the End provides a contextual overview and individual description and analysis of the wide range of depictions of the end of the world that have appeared in American popular culture. American writers, filmmakers, television producers, and game developers inundated the culture with hundreds of imagined apocalyptic scenarios, influenced by the Biblical Book of Revelation, the advent of the end of the second millennium (2000 CE), or predictions of catastrophic events such as nuclear war, climate change, and the spread of AIDS. From being "raptured" to surviving the zombie apocalypse, readers and viewers have been left with an almost endless sequence of disasters to experience. Imagining the End examines this phenomenon and provides a context for understanding, and perhaps appreciating, the end of the world. This title is composed of alphabetized entries covering all topics related to the end times, covering popular culture mediums such as comic books, literature, films, and music.

Download or read book Science in Public written by Jane Gregory and published by ReadHowYouWant.com. This book was released on 2010 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does the general public need to understand science? And if so, is it scientists' responsibility to communicate? Critics have argued that, despite the huge strides made in technology, we live in a ''scientifically illiterate'' society--one that thinks about the world and makes important decisions without taking scientific knowledge into account. But is the solution to this ''illiteracy'' to deluge the layman with scientific information? Or does science news need to be focused around specific issues and organized into stories that are meaningful and relevant to people's lives? In this unprecedented, comprehensive look at a new field, Jane Gregory and Steve Miller point the way to a more effective public understanding of science in the years ahead.

Download or read book Ancient Mysteries written by Peter James and published by Ballantine Books. This book was released on 2001-10-30 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, philosophers, scientists, and charlatans have attempted to decipher the baffling mysteries of our past, from Stonehenge to the lost continent of Atlantis. Today, however, DNA testing, radiocarbon dating, and other cutting-edge investigative tools, together with a healthy dose of common sense, are guiding us closer to the truth. Now historian Peter James and archaeologist Nick Thorpe tackle these age-old conundrums, presenting the latest information from the scientific community–and the most startling challenges to traditional explanations of mysteries such as: • The rise and fall of the Maya • A lost cache of Dead Sea Scrolls • The curse of Tutankhamun • The devastation of Sodom and Gomorrah • The Nazca Lines and the Vinland Map • The existence of Robin Hood These true mystery stories twist and turn like a good whodunit, as James and Thorpe present the evidence for and against the expert theories, shedding new light on humankind’s age-old struggle to make sense of the past. Ancient Mysteries will entertain and enlighten, delight the curious and inform the serious.
