Book excerpt: When in 1981 Louis and Walter Alvarez, the father and son team, unearthed a tell-tale Iridium-rich sedimentary horizon at the 65 million years-old Cretaceous-Tertiary boundary at Gubbio, Italy, their find heralded a paradigm shift in the study of terrestrial evolution. Since the 1980s the discovery and study of asteroid impact ejecta in the oldest well-preserved terrains of Western Australia and South Africa, by Don Lowe, Gary Byerly, Bruce Simonson, Scott Hassler, the author and others, and the documentation of new exposed and buried impact structures in several continents, have led to a resurgence of the idea of the catastrophism theory of Cuvier, previously largely supplanted by the uniformitarian theory of Hutton and Lyell. Several mass extinction of species events are known to have occurred in temporal proximity to large asteroid impacts, global volcanic eruptions and continental splitting. Likely links are observed between asteroid clusters and the 580 Ma acritarch radiation, end-Devonian extinction, end-Triassic extinction and end-Jurassic extinction. New discoveries of ~3.5 – 3.2 Ga-old impact fallout units in South Africa have led Don Lowe and Gary Byerly to propose a protracted prolongation of the Late Heavy Bombardment (~3.95-3.85 Ga) in the Earth-Moon system. Given the difficulty in identifying asteroid impact ejecta units and buried impact structures, it is likely new discoveries of impact signatures are in store, which would further profoundly alter models of terrestrial evolution. .

This book was released on 2018-03-12 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of Australian impact structures and related mineralization, including a discussion of the significance of many of these structures for crustal evolution. The book focuses in particular on Archaean impact ejecta/fallout units in the Pilbara Craton of Western Australia, large exposed and buried impact structures, and on the geophysical evidence for possible to probable impact structures. Thanks to their long-term geological stability, Precambrian and younger terrains in the Australian continent contain 38 confirmed impact structures and 43 ring and dome structures, many of which constitute possible to probable asteroid impact structures. The impact structures have been the subject of more than half a century of studies and range from several tens of meter-large craters to buried structures larger than 100 km in diameter. Discoveries of impact fallout units in the Pilbara Craton have defined the Pilbara as one of the two best documented terrains where Archaean impact ejecta/fallout deposits are identified, the other terrain being the Kaapvaal Craton in southern Africa. A synthesis of evidence from both cratons indicates periods of large asteroid bombardments during ~3.47 – 2.48 billion years-ago, including peak bombardment about 3.25—3.22 billion years-ago. The latter period coincides with an abrupt transformation of an early Archaean granite-greenstone crust to mid to late Archaean semi-continental crustal regimes, underpinning the significance of heavy asteroid impact events for crustal evolution. Apart from proven impact structures, Australian terrains display a range of circular features, including morphological and drainage rings, circular lakes, volcanic craters, tectonic domes, oval granite bodies, mafic igneous plugs, salt diapirs, and magnetic, gravity and seismic anomalies, many of which are of a likely impact origin. Thermal and hydrothermal processes associated with impact cratering bear important consequences for the formation of mineral deposits, such as Ni at Sudbury, Pb-Zn at Siljan and Kentland. Impact structures may also provide sites for the accumulation of hydrocarbons, whereas in some instances fracturing associated with impact structures allows outward migration of oil and gas.

This book was released on 2019-02-18 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The permutation of basic atoms—nitrogen, hydrogen, oxygen, carbon and phosphorus―into the biomolecules DNA and RNA, subsequently evolved in cells and brains, defining the origin of life and intelligence, remains unexplained. Equally the origin of the genetic information and the intertwined nature of ‘hardware’ and ‘software’ involved in the evolution of bio-molecules and the cells are shrouded in mystery. This treatise aims at exploring individual and swarm behaviour patterns which potentially hint at as yet unknown biological principles. It reviews theories of evolution with perspectives from the earth sciences, commencing with the earliest observed records of life. This is followed by reviews and discussion of the building blocks of life, marine and terrestrial communities, the arthropods, birds and finally humans. It is suggested that, further to the mutation/natural selection processes established by Darwin and Wallace, an understanding of the evolution of intelligence remains little understood. A directionality of evolutionary trajectories is evident, not least the purposeful thinking process of humans as well as animals. It is not clear how directional intelligence, manifested for example by the collective intelligence of arthropod colonies, has evolved from mutation/natural selection processes. Potential clues for the understanding of life and evolution are provided by Aristotle’s dictum of “the whole being greater than the sum of the parts”, Niels Bohr’s principle of quantum complementarity and George Ellis’ theory of top-down causality. Inherent in the question of the origin of life is an anthropocentric bias, related to the self-referential Anthropic Principle and theological paradigms of man’s supposed dominion over all other species. The Anthropic Principle, however, should be capable of being circumvented using the scientific falsification method, assuming universal verified constants of physics. The phenomenon of the human mastery of fire and the splitting of the atom, leading to the seventh major mass extinction of species, remains incomprehensible.

Available in PDF, EPUB and Kindle. Book excerpt: Questions about the origin and nature of Earth and the life on it have long preoccupied human thought and the scientific endeavor. Deciphering the planet's history and processes could improve the ability to predict catastrophes like earthquakes and volcanic eruptions, to manage Earth's resources, and to anticipate changes in climate and geologic processes. At the request of the U.S. Department of Energy, National Aeronautics and Space Administration, National Science Foundation, and U.S. Geological Survey, the National Research Council assembled a committee to propose and explore grand questions in geological and planetary science. This book captures, in a series of questions, the essential scientific challenges that constitute the frontier of Earth science at the start of the 21st century.

Book excerpt: In Impact, Gerrit L. Verschuur offers an eye-opening look at catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility. Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year mostly in meteoric form. But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth.

Book excerpt: One of the most dramatic intellectual events of the last decade has been the stunning re-emergence of the catastrophist paradigm in the biological and earth sciences From killer asteroids to emergent viruses, it has become evident that the history of life on earth has been shaped—far more than previous orthodoxies would allow ... by extreme events and non-linear processes. The old "uniformitarian" dogma of steady-rate evolution has been decisively challenged by the research of contemporary neo-catastrophists like Stephen Jay Gould, David Raup, Stuart Ross Taylor, Ursula Marvin and Kenneth Hsu. Whether debating the origin of the moon or the current human impact on the biosphere, they urge us to recognize the radically event- or chance-driven structure of natural history. Surveying these various theories of uniformitarian and neo-catastrophist thought in a clear and accessible fashion, and seeking a path towards a new and workable synthesis, Richard Hugget provides a superb introduction to the ideas which have defined the way we look at the world.

Book excerpt: In the vast expanse of the cosmos, celestial bodies journey through space, their paths occasionally crossing with our own planet Earth. Among these wanderers are asteroids, mysterious remnants of our solar system's formation that can pose potential threats to our world. Throughout history, Earth has endured the impact of asteroids, leaving lasting marks on our planet's landscape and shaping the course of evolution. Today, as we delve deeper into the realm of space exploration, understanding and mitigating the dangers posed by these wandering rocks have become crucial endeavors. "Asteroid Collision: Threats and Solutions" delves into the intriguing and thoughtprovoking realm of asteroids and the potential risks they pose to Earth. This book is an exploration into the fascinating world of space science, planetary defense, and humanity's quest to safeguard our planet and its inhabitants from potential impact events. As we traverse the pages of this book, we embark on a journey through the formation of our solar system and the genesis of these celestial hazards. We delve into the science behind asteroids, their classifications, and how their paths could intersect with ours. From the catastrophic impact events of the past to the future collision scenarios we may face, we delve into the science of asteroid impacts and their potential consequences. With an indepth analysis of asteroid detection and monitoring techniques, we unravel the cuttingedge technologies and space missions that pave the way for early warning systems and preparedness strategies. From telescopes that peer into the depths of space to spacecraft that journey to distant asteroids, we discover the ingenuity of human ingenuity in deciphering the secrets of the cosmos. The book examines the innovative strategies to divert and mitigate asteroid threats, from theoretical models to practical missions, revealing how science and technology join forces to protect our planet from potential cosmic calamities. It explores the international collaboration and global networks that unite nations in their shared responsibility to safeguard Earth from celestial impacts. As we gaze upward and outward, contemplating the mysteries of the universe, we also turn our attention to the ethical and legal considerations of planetary defense. Questions of responsibility, transparency, and international protocols are explored as we endeavor to create a unified front in safeguarding humanity's future. "Asteroid Collision: Threats and Solutions" is not just a book of knowledge; it is a call to action. It is an invitation to explore the unknown, to embrace the wonders of our universe, and to unite in protecting the fragile oasis we call home. Our collective journey to understand, prepare, and respond to potential asteroid threats symbolizes the human spirit of exploration and resilience. This book aims to inspire scientists, astronomers, policymakers, and the general public alike to engage in planetary defense efforts. It is a testament to the power of knowledge and collaboration, reminding us that together, we can navigate the challenges that lie beyond the stars. Let us embark on this cosmic voyage with curiosity and determination, driven by the desire to secure a safer future for our planet and generations yet to come.

Book excerpt: Part art history essay, part experimental fiction, part theoretical manifesto on the politics of equivalence, Helicography examines questions of scale in relation to Robert Smithson's iconic 1970 artwork Spiral Jetty. In an essay and film made to accompany the earthwork, Smithson invites us to imagine the stone helix of his structure at various orders of magnitude, from microscopic molecules to entire galaxies. Taking up this invitation with an unrelenting and literal enthusiasm, Helicography pursues the implications of such transformations all the way to the limits of logic. If other spirals, from the natural to the man-made, were expanded or condensed to the size of Spiral Jetty, what are the consequences of their physical metamorphoses? What other equivalences follow in turn, and where do their surprising historical, cultural, and mechanical connections lead? This book considers a number of forms in order to find out: the fluid vortices of whirlpools, hurricanes, and galaxies; the delicate shells of snails and the threatening pose of rattlesnakes; prehistoric ferns and the turns of the inner ear; the monstrous jaws of ancient sharks; a baroque finial scroll on a bass viol; a 19th-century watch spring; phonograph discs and spooled film; the largest open-pit mine on the planet. The result is a narrative laboratory for the "science of imaginary solutions" proposed by Alfred Jarry (whose King Ubu also plays a central role in the story told here), a work of fictocriticism blurring form and content, and the story of a single instant in time lost in the deserts of the intermountain west. Craig Dworkin is the author of four scholarly monographs - Reading the Illegible (Northwestern University Press), No Medium (MIT Press), Dictionary Poetics: Toward a Radical Lexicography (Fordham University Press), and Radium of the Word: a Poetics of Materiality (Chicago University Press) - as well as a half-dozen edited collections and a dozen books of experimental writing, including, most recently, The Pine-Woods Notebook (Kenning Editions). He teaches literary history and theory at the University of Utah.
