Das Unsterblichkeitsproblem

Grundannahmen und Voraussetzungen (Teil I / Teil II)

Fünf zentrale Annahmen werden immer wieder angeführt, um die Unsterblichkeit zu negieren: Es gebe nur die physische Welt; keine Hinweise auf andere Wirklichkeitsbereiche oder Dimensionen seien vorhanden. Die Lebewesen seien ohne Absicht ausschließlich durch rein mechanistisch-materialistische Prozesse entstanden. Es gebe keine rationalen Argumente für die Existenz einer transzendenten Wirklichkeit. Das Bewusstsein sei ein Produkt der Komplexität des Nervensystems; es gebe keine Belege für die Transmissionshypothese, nach der das Hirn wie ein Transmitter für ein eigenständiges Bewusstsein wirkt. Schließlich sei in der Aufklärung gezeigt worden, dass die Vorstellung einer unsterblichen Seele irrational sei. Die Autorin prüft, inwieweit diese Annahmen gesichert sind. Sie zeigt im Detail, dass es gute Belege – wenn auch keine zwingenden Beweise – für die Unabhängigkeit und die Trennbarkeit des Bewusstseins vom physischen Körper, die postmortale Kontinuität des Bewusstseins und die Unsterblichkeitshypothese gibt.Die Arbeit kombiniert existenz- und naturphilosophische Fragestellungen mit mathematischen, physikalischen, biologischen und neurowissenschaftlichen Perspektiven und bietet so einen umfassenden Blick auf das Problem der Unsterblichkeit.

Jedem Stadtbewohner f?llt auf, dass wir nachts aufgrund immer heller werdender k?nstlicher Beleuchtung kaum mehr Sterne am Himmel sehen k?nnen. Doch dies ist nur die Spitze des Eisbergs, was den Verlust nat?rlicher n?chtlicher Dunkelheit betrifft. Menschen und Tiere - darunter Nachtfalter, Zugv?gel und Meeresschildkr?ten - leiden mittlerweile rund um den Globus an der Zerst?rung des Tag-Nacht-Rhythmus durch die ?berm??ige Erhellung der Nacht. Beim Menschen k?nnen Krankheiten und eine Zunahme von Stress die Folgen sein. Das gesamte Ph?nomen, das bisher nur in Fachkreisen bekannt war, wird in diesem Werk erstmals umfassend und reichhaltig illustriert vorgestellt - von Experten aus Deutschland, der Schweiz, ?sterreich und den USA. Es ist f?r jeden geeignet, der sich f?r ein harmonisches Miteinander von Mensch und Natur sowie einen gesunden Arbeits- und Lebensrhythmus interessiert. Das Buch beruht auf der Fernsehdokumentation "The Dark Side of Light" von Anja Freyhoff und Thomas Uhlmann. W?hrend der Dreharbeiten ist reichhaltiges und ungew?hnliches Bildmaterial entstanden, das die "dunkle Seite" des Lichts aussagekr?ftig illustriert.

Weird Scientists – the Creators of Quantum Physics

Author: Jeffrey Strickland

Publisher: Lulu.com

ISBN: 1257976249

Category: History

Page: 570

View: 1250

Weird Scientists is a sequel to Men of Manhattan. As I wrote the latter about the nuclear physicists who brought in the era of nuclear power, quantum mechanics (or quantum physics) was unavoidable. Many of the contributors to the science of splitting the atom were also contributors to quantum mechanics. Atomic physics, particle physics, quantum physics, and even relativity are all interrelated. This book is about the men and women who established the science that shook the foundations of classical physics, removed determinism from measurement, and created alternative worlds of reality. The book introduces fundamental concepts of quantum mechanics, roughly in the order they were discovered, as a launching point for describing the scientist and the work that brought forth the concepts.

Bees

Their Vision, Chemical Senses, and Language

Author: Karl von Frisch

Publisher: Cornell University Press

ISBN: 0801471761

Category: Science

Page: 176

View: 7537

Over half a century of brilliant scientific detective work, the Nobel Prize-winning biologist Karl von Frisch learned how the world, looks, smells, and tastes to a bee. More significantly, he discovered their dance language and their ability to use the sun as a compass. Intended to serve as an accessible introduction to one of the most fascinating areas of biology, Bees (first published in 1950 and revised in 1971), reported the startling results of his ingenious and revolutionary experiments with honeybees. In his revisions, von Frisch updated his discussion about the phylogenetic origin of the language of bees and also demonstrated that their color sense is greater than had been thought previously. He also took into consideration the electrophysiological experiments and electromicroscopic observations that have supplied more information on how the bee analyzes polarized light to orient itself and how the olfactory organs on the bee's antennae function. Now back in print after more than two decades, this classic and still-accurate account of the behavior patterns and sensory capacities of the honeybee remains a book “written with a simplicity, directness, and charm which all who know him will recognize as characteristic of its author. Any intelligent reader, without scientific training, can enjoy it.”—Yale Review

"The proposed three volumes are the latest installment in Ian Howard's amazing ongoing project of providing the most comprehensive review available anywhereof all aspects of how humans and animals perceive and navigate the three-dimensional world. The current book set is even more complete in its coverage than the two previous editions have been. With 37 chapters, 1800 illustrations, and 8,000 references, it covers psychophysics, coding, physiology, development of systems and functions, results of deprivation, accommodation, physiology of disparity, binocular fusion and rivalry, binocular correspondence and the horopter, linking binocular images, cyclopean perception, stereo acuity, uses of disparity, stereopsis and perceptual organization, the Pulfrich effect, stereoscopic techniques and applications, distinguishing depth from vergence, perspective, shading, and motion parallax, constancies in visual depth perception, cue integrations, motion in depth, pathology of visual depth perception, animal depth perception, feeling, reaching, and moving, auditory distance perception, electrolocation and the thermal senses, as well as comprehensive coverage of animal navigation that could be a book on its own. Ian Howard's books have become landmarks in the field of vision science, and this current project will definitely maintain the tradition for researchers in space perception, visual neuroscience, ophthalmology, optometry, visual development, animal vision, and computational vision"--

The Behaviour of Teleost Fishes

Author: Tony J. Pitcher

Publisher: Springer Science & Business Media

ISBN: 1468482610

Category: Science

Page: 553

View: 8807

This book is about the behaviour of teleosts, a well-defined, highly successful, taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are weH over 22000 living species of teleosts, including nearly all those of importance in com mercial fisheries and aquaculture. Teleosts are represented injust about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour is the primary interface between these effective survival machines and their environment: behavioural plasticity is one of the keys to their success. The study of animal behaviour has undergone revolutionary changes in the past decade under the dual impact of behavioural ecology and sociobiology. The modern body of theory provides quantitatively testable and experi mentaHy accessible hypotheses. Much current work in animal behaviour has concentrated on birds and mammals, animals with ostensibly more complex structure, physiology and behavioural capacity, but there is a growing body of information about the behaviour of fishes. There is now increasing awareness that the same ecological and evolutionary rules govern teleost fish, and that their behaviour is not just a simplified version of that seen in birds and mammals. The details of fish behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment.

these. In this book, we appropriate their conception of research-technology, and ex tend it to many other phenomena which are less stable and less localized in time and space than the Zeeman/Cotton situation. In the following pages, we use the concept for instances where research activities are orientated primarily toward technologies which facilitate both the production of scientific knowledge and the production of other goods. In particular, we use the tenn for instances where instruments and meth ods· traverse numerous geographic and institutional boundaries; that is, fields dis tinctly different and distant from the instruments' and methods' initial focus. We suggest that instruments such as the ultra-centrifuge, and the trajectories of the men who devise such artefacts, diverge in an interesting way from other fonns of artefacts and careers in science, metrology and engineering with which students of science and technology are more familiar. The instrument systems developed by re search-technologists strike us as especially general, open-ended, and flexible. When tailored effectively, research-technology instruments potentially fit into many niches and serve a host of unrelated applications. Their multi-functional character distin guishes them from many other devices which are designed to address specific, nar rowly defined problems in a circumscribed arena in and outside of science. Research technology activities link universities, industry, public and private research or me trology establishments, instrument-making finns, consulting companies, the military, and metrological agencies. Research-technology practitioners do not follow the career path of the traditional academic or engineering professional.

Einführung in die Atomphysik

Author: Wolfgang Finkelnburg

Publisher: Springer-Verlag

ISBN: 3662014327

Category: Science

Page: 543

View: 1962

Die Atomphysik in dem weiteren Sinne, in dem sie in diesem Buch dargestellt werden soll, ist die Lehre vom Aufbau der Materie aus den letzten Elementar teilchen sowie von deren Eigenschaften und Wirkungen; sie sucht die gesamte un geheure Mannigfaltigkeit der stofflichen Erscheinungen unserer Welt mittels mög lichst weniger Elementarteilchen, allgemeiner Grundgesetze und Naturkonstanten einheitlich zu verstehen. Diese Lehre von der "atomistischen" Struktur der Atom kerne, Atome, Moleküle und Kns1alle, d. h. der gesamten Materie, ist, obwohl ihre Anfänge in das vorige Jahrhundert zurückreichen, doch eindeutig das Ergebnis der Physik des zo. Jahrhunderts, an dessen Schwelle PLANCKS Entdeckung des elementaren Wirkungsquantums h und seiner universellen Bedeutung den Beginn der Quantentheorie markiert, die den Schlüssel zum Verständnis aller Erschei nungen der Atomphysik lieferte und unter deren Zeichen der überwiegende Teil der physikalischen Forschungsarbeit unseres Jahrhunderts steht. 1. Die Bedeutung der Atomphysik für Wissenschaft und Technik. Die neue Auffassung von der Materie und damit von den letzten Grundlagen der Physik und Chemie, die sich aus der Atomphysik entwickelte, hat auch unsere Kenntnis von zahlreichen, seit langem wohlbekannten Gebieten der Physik in solchem Maß umgestaltet, daß man heute vielfach das um die Jahrhundertwende weitgehend vollendete Gebäude der Physik ohne Berücksichtigung der quanten haften atomaren Erscheinungen als "klassische Physik" bezeichnet und ihm als "moderne Physik" eine vom atomphysikalischen Standpunkt aus aufgefaßte Physik gegenüberstellt.
