Abstract

Wie das Denken funktioniert, ist noch immer ein Geheimnis der Natur. Die Neurowissenschaften machen jedoch in jüngster Zeit zunehmend Fortschritte bei der Beantwortung dieser - auch für unser gesamtes Selbstverständnis - grundlegenden Frage. Dabei spielen Untersuchungsmethoden aus der Physik und der Einsatz modernster Computertechnologie eine immer wichtigere Rolle. Welche Chancen eröffnen sich, wenn wir besser verstehen, wie im Gehirn Wahrnehmung, Informationsverarbeitung und Kreativität stattfinden? Diese Frage steht im Zentrum der Futur-Leitvision "Das Denken verstehen". Das bereits in der Anfangsphase von Futur entstandene Thema wurde zu einem späteren Zeitpunkt des Prozeses wieder aufgegriffen und aufgrund der erheblichen Bedeutung, die das Thema für die Lernforschung, den Gesundheitsbereich und die technische Informationsverarbeitung (einschließlich der Robotik) hat, zur Leitvision weiterentwickelt.

Abstract

Die Physik ist bei der Jagd nach der Weltformel in einer Sackgasse gelandet. Immer wieder wird verkündet, die Formel sei fast gefunden. Nur: Wo bleibt sie dann? Der Autor zeichnet nach, wie die theoretische Physik vom Weg abkam und nun mit immer größeren Spekulationsblasen in die Esoterik abdriftet. Witzig-bissig und mit unterhaltsamen Anekdoten, aber auch fundiert bis ins Detail nimmt er die heutige Mode der Physik aufs Korn und erinnert an die unbeantworteten Fragen, die die wirklichen Größen der Physik bewegt haben. Trotz oder gerade wegen der kritischen Töne ein faszinierendes und nachdenklich machendes Plädoyer für die Wissenschaft.

Abstract

In seinem Klassiker erläutert der international führende Mathematiker und Physiker, Sir Roger Penrose, seine These, dass die geistigen Fähigkeiten des menschlichen Gehirns nicht durch Berechnungen von Elektronengehirnen erreicht werden können - und provozierte eine neue KI-Debatte. . . . des Kaisers neue Kleider - steht auf dem Buchumschlag. Der renommierte englische Physiker Penrose will damit sichtbar machen, daß die Vertreter der Künstlichen Intelligenz (KI) nackt dastehen. Mit einem 400 Seiten langen Exkurs versucht er, ihre Behauptung zu widerlegen, daß Maschinen ebenso intelligent sein können wie Menschen. bild der wissenschaft Roger Penrose ( . . . ) gelang das Kunststück, mit dem formelgespickten Wälzer "The Emperors's New Mind" (auf deutsch jetzt unter dem geistlosen Titel "Computerdenken" erschienen) auf den US-Bestsellerlisten zu landen, ungeachtet aller Quanten-Ket-Vektoren und Einsteinscher Krüümungstensoren, mit denen der Autor seine Leser plagt. DER SPIEGEL Das erklärte Ziel dieses Buches ist, den Standpunkt einiger KI-Enthusiasten zu widerlegen, daß Computer irgendwann all das können, was menschliche Gehirne können - und sogar mehr. Aber der Leser merkt bald, dass Pnerose vor allem das Ziel verfolgt, einen Wegzur großen Synthese von klassischer Physik, Quantenphysik und Neurowissenschaften aufzuzeigen. John Horgan in Scientific American Wer "Computerdenken" liest (oder durcharbeitet), sollte nicht auf Antwort hoffen, darf aber neue Sichtwiesen und überraschende Interpretationen erwarten. Ein nahrhaftes Geschenk für naturwissenschaftlich Interessierte. Die Zeit Trotz des mathematichen Themas wurde The Emperor's New Mind prompt ein Bestseller und sein Autor zum bestgehaßten Mann der KI-Szene ( . . . ).

Abstract

Vor rund drei Jahren sorgte eine Skandal auf beiden Seiten des Atlantiks für heiße Dikussionen unter Gelehrten und Feuilletonisten. Alan Sokal, ein New Yorker Physikprofessor, veröffentlichte damals in einer angesehenen amerikanischen Soziologie-Fachzeitschrift einen pseudowissenschaftlichen Artikel, den er mit theoretischen Absurditäten aus Physik und Mathematik spickte. Damit tat er, was seiner Meinung nach in der aktuellen Geisteswissenschaft ohnehin gang und gäbe ist: die Verfremdung der hard sciences in den Werken der postmodernen Theoretiker. In diesem Buch dokumentiert der Urheber seinen "Scherz". Neben einem gründlichen Kommentar zu dem Artikel, der hier freilich nicht fehlt, liefern die Autoren eine eingehende Diskussion wichtiger postmoderner Theoretiker, die ausgiebig in der Naturwissenschaft gewildert haben. In Einzelkapiteln wird aufgeschlüsselt, wie fahrlässig Lacan, Kristeva, Deleuze und Guattari, Virilio, Baudrillard und andere mit Axiomen der Mathematik und Physik umgehen. Beispiel: Heisenberg. Dessen Unschärferelation besagt unter anderem, daß bei der Beobachtung eines Teilchens der Beobachtungsvorgang in den Vordergrund rückt. Oder anders: Naturwissenschaftliches Beobachten bringt nicht ein Naturbild hervor, sondern "ein Bild unser Beziehung zur Natur" -­ ein Ergebnis, daß von der poststrukturalistischen bzw. konstruktivistischen Theorieavantgarde vielfach zur metaphorischen Grundlage einer metaphysischen Skepsis gegenüber Konzepten wie Identität, Existenz und Wahrheit gemacht wurde. Sokal und Bricmont richten sich im kleinen also gegen den Mißbrauch der Naturwissenschaften als Metaphernlieferant. Dahinter steht die Abneigung gegen den uneingeschränkten Relativismus, den die postmoderne Theorie verherrlicht: alles ist beobachterabhängig, Wissenschaft ist Text, die Wahrheit subjektiv. Eleganter Unsinn ist deshalb vor allem eine ernstzunehmende Auseinandersetzung mit dem philosophischen Skeptizismus von Hume und Descartes bis Popper, Kuhn und Feyerabend. Es ist eine nüchterne, klarsichtige Bestandsaufnahme der jüngsten Wissenschaftgeschichte mit dem Versuch, den Streit zwischen den "zwei Kulturen" Natur- und Geisteswissenschaft argumentativ zu schlichten.

Abstract

Die Berücksichtigung der Informationsbedarfe und Informationsgewohnheiten ihrer jeweiligen Zielgruppe ist ein wesentliches Charakteristikum desAngebots der Virtuellen Fachbibliotheken Technik und Physik: Von Ingenieuren und Physikern gestellte Anforderungen an ein Informationsangebot werden in den Virtuellen Fachbibliotheken Technik und Physik umgesetzt, um demAnspruch gerecht zu werden, einen integrierten Zugang zu fachrelevanten Informationen und Dienstleistungen zu bieten. Dabei ist nicht nur bei derAuswahl der bereitgestellten Informationsquellen, sondern insbesondere auch bei derAufbereitung (wie z.B. der sachlichen Erschließung) und Präsentation der Inhalte und Angebote der Virtuellen Fachbibliotheken auf fachspezifische Gewohnheiten und Konventionen zu achten. Kooperationen z.B. mit Fachwissenschaftlern und mit Informationslieferanten sind für die Bereitstellung eines umfassenden und qualitativ hochwertigen Angebots wesentlich.
