Nature’s Biodiversity: The Search, for Beginnings and for Order

by Joseph Heller

This book is about our quest over the centuries, from ancient Greece onwards, for pattern in the rich diversity of life. How did our ancestors think that living creatures first came to be, each fitting so well to its specific environment? Does biodiversity have a purpose? What biodiversity exists, beyond what our eyes can see? Do dragons and unicorns exist? How did the world begin, how did order emerge and were there several Creation events? Reproduction resembles Creation in that order appears out of nothing, form out of matter. Can different reproduction modes increase biodiversity? Why sexual reproduction? Can living creatures, and hence biodiversity, arise from non-living dust? How do embryos develop, from a featureless mass into an orderly, organised living body? Does embryonic development dictate diversity and do species ever go extinct? What is a soul? Do animals have souls? Do souls migrate, between man and animal? Does inheritance of acquired characters create biodiversity? Does diversity form an orderly ladder from plants through animals to Man, or perhaps orderly circles-within-circles? These questions and many others have been central to our culture&’s overall view of nature, from ancient times onwards. This book, presenting the urge to understand overall pattern in the diversity of life throughout history, takes a broad approach. It links theories of classification with those of reproduction, embryology, theology and (eventually) evolution, as they developed from ancient days onwards, over 2400 years. Over 250 illustrations accompany the text, many taken from the ancient, original treatises, many others painted especially for this book, to present specific animals or ideas. This comprehensive view of the study of biodiversity will appeal to zoology lecturers and students, biology teachers and amateur naturalists, as well as to lecturers and learners of history, of theology; and of course, to anybody seeking to broaden horizons.

Nature’s Clocks: How Scientists Measure the Age of Almost Everything

by Doug Macdougall

"Radioactivity is like a clock that never needs adjusting," writes Doug Macdougall. "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating--the best known of these methods--and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves--James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson--Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

Naturschutz: Eine kritische Einführung

by Klaus-Dieter Hupke

In Naturschutzgebieten geschieht vieles, das auf den ersten Blick widersprüchlich ist. So werden beim Pflegeeinsatz Blumenwiesen abgemäht, wo doch alle dort wachsenden Pflanzen unter Naturschutz stehen. An anderer Stelle werden im Flachmoor geschützte Schilfbestände abgebrannt oder in einem Dünenschutzgebiet die oberste Bodenschicht mit Planierraupen abgetragen. Wiederum andere Flächen sollen völlig unberührt von menschlichen Eingriffen bleiben. Der Autor Klaus-Dieter Hupke zeigt die verschiedenen Strategien von Naturschutz auf. Er zeigt auch, dass Naturschutz zumeist gerade das nicht ist, was der Begriff im Kern aussagt: „Schutz der Natur“. In Mitteleuropa handelt es sich bei Naturschutzgebieten im Gegenteil überwiegend um die Relikte alter Agrar- und damit Kulturlandschaften. Oftmals stehen auch ästhetische Aspekte eines Landschaftsausschnitts bei der Ausweisung als Naturdenkmal oder Naturschutzgebiet im Vordergrund. Darüber hinaus läuft der Naturschutz Gefahr, zur Ersatzhandlung und zum Alibi für eine in Mitteleuropa wie global immer noch wachsende Zerstörung traditioneller und naturnaher Landschaftssysteme zu werden.Die aktualisierte zweite Auflage bezieht die Folgen des Klimawandels für den Naturschutz nun explizit ein und hat auch an einigen Stellen für die entsprechenden Leser einen stärkeren Bezug auf Österreich sowie auf den zentralalpinen Raum eingearbeitet.

Natürliche und künstliche Intelligenz: Ein kritischer Vergleich

by Gerhard Roth Lukas Tuggener Fabian Christoph Roth

Dieses Sachbuch fasst die wissenschaftlichen Grundlagen der natürlichen und künstlichen Intelligenzsysteme zusammen und analysiert ihre Leistungen in einem kritischen Vergleich. Fachkenntnisse sind keine Voraussetzung. Nach einer Einführung in die Intelligenzforschung folgt die Beschreibung menschlicher und tierischer Intelligenz und deren neurobiologischen Grundlagen. Dieser natürlichen Intelligenz wird im Anschluss die künstliche Intelligenz gegenübergestellt, wobei die wichtigsten Grundprinzipien und die Entwicklung hin zu heutigen KI-Systemen betrachtet werden. Dies beinhaltet auch die wichtige Frage, inwiefern KI-Systeme vom Gehirn und dessen Arbeitsweisen lernen können und ob durch das „Nachbauen“ von Nervenzellenverbünden mit den sogenannten neuromorphen Chips vergleichbare Leistungen erreichbar sind oder sein werden. Ein besonderer Fokus liegt auf der kritischen Betrachtung und Einordnung der Fähigkeiten von KI-Systemen in Hinblick auf Denken und Handeln als eine selbstständige Entscheidungsinstanz. Letzteres wirft Fragen hinsichtlich moralischer Entscheidungen und des möglichen Kontrollverlusts über solche Systeme auf, die zurzeit nicht abschließend beantwortet werden können

Naval Forces' Defense Capabilities Against Chemical and Biological Warfare Threats

by Committee for an Assessment of Naval Forces' Defense Capabilities Against Chemical Biological Warfare Threats

This book reviews a draft report from the federal government that assesses the effects of oxygenated gasoline on public health, air quality, fuel economy, engine performance, and water quality. In addition to evaluating the scientific basis of the report, the book identifies research needed to better understand the impacts of oxygenated fuels. Methyl tertiary-butyl ether (MTBE), which is intended to reduce carbon monoxide pollution during winter, is the most commonly used additive in the federal oxygenated fuels program. MTBE has been implicated in complaints by the public of headaches, coughs, and nausea. Other questions have been raised about reduced fuel economy and engine performance and pollution of ground water due to the use of MTBE in gasoline. The book provides conclusions and recommendations about each major topic addressed in the government's report.

Navier-Stokes Turbulence: Theory and Analysis

by Wolfgang Kollmann

The book serves as a core text for graduate courses in advanced fluid mechanics and applied science. It consists of two parts. The first provides an introduction and general theory of fully developed turbulence, where treatment of turbulence is based on the linear functional equation derived by E. Hopf governing the characteristic functional that determines the statistical properties of a turbulent flow. In this section, Professor Kollmann explains how the theory is built on divergence free Schauder bases for the phase space of the turbulent flow and the space of argument vector fields for the characteristic functional. Subsequent chapters are devoted to mapping methods, homogeneous turbulence based upon the hypotheses of Kolmogorov and Onsager, intermittency, structural features of turbulent shear flows and their recognition.

Navigating Complexity in Big History: Exploring Periodization Across Cosmic and Biosocial Dimensions (World-Systems Evolution and Global Futures)

by Leonid Grinin Andrey Korotayev David J. LePoire

This book explores periodization in Big History against the background of complexity growth across the Universe, on our planet, and in biological, social, and cultural systems. It traces the accelerating rise in complexity throughout history and the major historical transformations involved in the evolution of life, humans, and civilization. It draws on concepts from physics and evolutionary biology to offer potential models of the underlying mechanisms driving this acceleration, along with potential clues to how it might end. In the editors&’ introduction (Chapter 1), the effort to periodize is placed within the historical context along with considerations from complexity science. Subsequent chapters explore various aspects of periodization and complexity by (a) identifying symmetrical cosmic and biosocial trends, (b) testing rigor and criteria for evaluating periodization, (c) attempting to integrate different approaches through multiple perspectives, (d) proposing different strategies for determining geometric patterns in terrestrial bio-social evolution, and (e) applying the traditional threshold model to gain insights into possible future pathways. A concluding chapter identifies commonalities, research gaps, and possible approaches to integration as the current state of the world system rapidly evolves, while also offering a deeper understanding of complexity dynamics and historical processes. Each chapter includes an extensive bibliography, allowing a deeper and more detailed examination of the issues covered.
