Download or read book Cataclysmic Cosmic Events and How to Observe Them written by Martin Mobberley and published by Springer Science & Business Media. This book was released on 2009-03-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.

Download or read book Ents Elves and Eriador written by Matthew T. Dickerson and published by University Press of Kentucky. This book was released on 2006-11-17 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many readers drawn into the heroic tales of J. R. R. Tolkien's imaginary world of Middle-earth have given little conscious thought to the importance of the land itself in his stories or to the vital roles played by the flora and fauna of that land. As a result, The Hobbit, The Lord of the Rings, and The Silmarillion are rarely considered to be works of environmental literature or mentioned together with such authors as John Muir, Rachel Carson, or Aldo Leopold. Tolkien's works do not express an activist agenda; instead, his environmentalism is expressed in the form of literary fiction. Nonetheless, Tolkien's vision of nature is as passionate and has had as profound an influence on his readers as that of many contemporary environmental writers. The burgeoning field of agrarianism provides new insights into Tolkien's view of the natural world and environmental responsibility. In Ents, Elves, and Eriador, Matthew Dickerson and Jonathan Evans show how Tolkien anticipated some of the tenets of modern environmentalism in the imagined world of Middle-earth and the races with which it is peopled. The philosophical foundations that define Tolkien's environmentalism, as well as the practical outworking of these philosophies, are found throughout his work. Agrarianism is evident in the pastoral lifestyle and sustainable agriculture of the Hobbits, as they harmoniously cultivate the land for food and goods. The Elves practice aesthetic, sustainable horticulture as they shape their forest environs into an elaborate garden. To complete Tolkien's vision, the Ents of Fangorn Forest represent what Dickerson and Evans label feraculture, which seeks to preserve wilderness in its natural form. Unlike the Entwives, who are described as cultivating food in tame gardens, the Ents risk eventual extinction for their beliefs. These ecological philosophies reflect an aspect of Christian stewardship rooted in Tolkien's Catholic faith. Dickerson and Evans define it as "stewardship of the kind modeled by Gandalf," a stewardship that nurtures the land rather than exploiting its life-sustaining capacities to the point of exhaustion. Gandalfian stewardship is at odds with the forces of greed exemplified by Sauron and Saruman, who, with their lust for power, ruin the land they inhabit, serving as a dire warning of what comes to pass when stewardly care is corrupted or ignored. Dickerson and Evans examine Tolkien's major works as well as his lesser-known stories and essays, comparing his writing to that of the most important naturalists of the past century. A vital contribution to environmental literature and an essential addition to Tolkien scholarship, Ents, Elves, and Eriador offers both Tolkien fans and environmentalists an understanding of Middle-earth that has profound implications for environmental stewardship in the present and the future of our own world.

Download or read book Nanozymology written by Xiyun Yan and published by Springer Nature. This book was released on 2020-01-30 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the new concept of “nanozyme”, which refers to nanomaterials with intrinsic enzymatic activity, rather than nanomaterials with biological enzymes incorporated on the surface. The book presents the cutting-edge advances in nanozyme, with emphasis on state-of-the-art applications in many important fields, such as in the biomedical fields and for environmental protection. The nanozyme is a totally new type of artificial enzyme and exhibits huge advantages over natural enzymes, including greater stability, low cost, versatility, simplicity, and suitability for industry. It is of interest to university researchers, R&D engineers, as well as graduate students in nanoscience and technology, and biology wishing to learn the core principles, methods, and the corresponding applications of “nanozyme”.

Download or read book Sundaland Tracing The Cradle of Civilizations written by Dhani Irwanto and published by INDONESIA HYDRO MEDIA. This book was released on 2019-02-22 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sundaland is a bio-geographical region of Southeastern Asia which encompasses the Sunda Shelf, the part of the Asian continental shelf that was exposed during the Last Ice Age. It included the Malay Peninsula on the Asian mainland, as well as the large islands of Kalimantan, Java and Sumatera, and their surrounding islands. Sundaland is in the tropics, surrounded by oceans, and within the Ring of Fire. Benefitting from the heavy precipitation, volcanic deposits in Sundaland develop into some of the richest forestry and agricultural lands, and developed into some of the richest fauna on Earth. The vast majority of scholars accept that every living human being is descended from a small group in Africa, who then dispersed into the wider world. Archaeological and fossil evidence support an early migration of modern humans left Africa and followed the coastlines of Africa, Arabia, India and Sundaland. After migrating from the semi-deserted savannas of Africa, man first found a place in Sundaland where food was abundant and it was there that they left hunter-gatherer culture and invented farming, agriculture, trading and civilization, which made humanity first flourished. All this took place during the Last Glacial period. The sea levels continued to rise gradually to peak levels about 5,500 years ago, causing land loss on tropical coasts with flat continental shelves. Cracks in the earth’s crust as the weight of the ice shifted to the seas set off catastrophic events compounded by earthquakes, volcano eruptions, super waves and floods drowned the coastal cultures and all the flat continental shelves of Southeast Asia, and wiped out many populations. As the sea rolled in, there was a mass migration from the sinking continent. Genetic studies show that there has been a sharp decline in the population of the world, and population turnovers from Southeast, East and South Asia to Europe, Near East and the Caucasus beginning at the the end of the Younger Dryas period. The Younger Dryas disasters are also documented as legends, myths or tales in almost every region on Earth, observable with tremendous similarities. They are common across a wide range of cultures, extending back into Bronze Age and Neolithic prehistory. The overwhelming consistency among legends and myths of flood and the repopulation of man from a flood hero similar to the Noah Flood are found in distant parts of the Earth. The myths similar to the Garden of Eden, Paradise or Divine Land echo among the populations around the world. Memories of their origin are documented in their legends, such as the stories of Atlantis, Neserser, Land of Punt, Land of Ophir, Kumari Kandam, Kangdez and Taprobana. Pyramids spread in many parts of the world and emerged separately from one another by oceans who supposedly never discovered each other’s existence. Those indicate that they were derived from a common origin. Further, scholastic belief by etymologists and linguists are positive that all world languages sprang from a common source.

Download or read book Exoplanets written by C. R. Kitchin and published by Springer Science & Business Media. This book was released on 2011-12-02 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exoplanets: Finding, Exploring, and Understanding Alien Worlds probes the basis for possible answers to the fundamentals questions asked about these planets orbiting stars other than our Sun. This book examines what such planets might be like, where they are, and how we find them. Until around ten years ago, the only planets that we knew about were within the Solar System. The first genuine planet beyond the confines of the Solar System was discovered only 1988. Since then another 350 or so exoplanets have been detected by various methods, and most of these haven been found in the last ten years. Although many more exoplanets discoveries may be expected to occur even as this book is being read, a large enough data set is now available to form the basis for an informed general account of exoplanets. The topic hence is an extremely "hot" one - all the more so because the recently launched Kepler spacecraft should soon start uncovering many more exoplanets, some perhaps comparable with the Earth (and therefore possibly alternative homes for mankind, if we could ever reach them). Exoplanets: Finding, Exploring, and Understanding Alien Life gives a comprehensive, balances, and above all accurate account of exoplanets.
