    Evolution, the Purpose of Life and the Order of Society

    This essay treats the pseudo-biographical monographs with which the Turkish author Halit Ertuğrul popularizes the teachings of Said Nursi, founder of the Nurcu movement. Rejection of the theory of evolution plays a central role in these narratives, where a religious person acts as a prompter who demonstrates to a person led astray by materialism the futility of his ideology. As soon as ‘the materialists’ have understood this, they change their life entirely and free themselves from the sociopolitical delusions of communism or behavioral problems. The theory of evolution functions in these accounts not only as a basis of atheism and materialism but also as the antithesis of a harmonious order of the cosmos, which ought to be reflected in a harmonious order of society. This paper is one of a collection that originated in the IAHR Special Conference “Religions, Science and Technology in Cultural Contexts:  Dynamics of Change”, held at The Norwegian University of Science and Technology on March 1–2, 2012.

    The Islamic Creationism of Harun Yahya

    Get PDF
    For some time Islamic publishing in the West has been associated with pamphlets in awkward English printed on pulp. Strolling through Islamic bookshops in Britain one immediately realizes how things have changed: beautifully edited books are offered for considerable prices. A notable part of these publications is dedicated to the defence of Islam against the challenges of Christianity and materialism. Outstanding examples for this new tendency are the writings of the prolific Turkish author Harun Yahya (pseudonym of Adnan Oktar), whose list of Turkish publications includes about 180 titles, most of them dedicated to the refutation of Darwinism

    Ein Cytochrom P450 2C8/9-abhÀngig gebildeter EDHF hyperpolarisiert Thrombozyten und hemmt deren AdhÀsion an Endothelzellen

    Im Rahmen dieser Dissertation wurde der potentielle Einfluss des endothelialen hyperpolarisierenden Faktors (EDHF) auf Thrombozyten untersucht und geprĂŒft, ob die EDHF Wirkungen durch eine (oder mehrere) EpoxyeicosatriensĂ€uren (Produkte der endothelialen CYP450 Monooxygenase) ausgelöst sein könnten. EDHF wurde bisher hauptsĂ€chlich, neben NO und Prostazyklin, als dritter funktionell bedeutender vom Endothel gebildeter vasodilatierender Faktor charakterisiert. FĂŒr NO und Prostazyklin ist vielfach eine Freisetzung in das GefĂ€ĂŸlumen und damit neben der lokalen dilatierenden Wirkung auch eine Beeinflussung zirkulierender Blutbestandteile, wie Thrombozyten beschrieben. Beide können die thrombozytĂ€re Aktivierung und Aggregation effektiv hemmen und dadurch gefĂ€ĂŸprotektive Wirkungen ausĂŒben. Ob EDHF ebenfalls Blutbestandteile wie Thrombozyten beein-flussen kann, war die Hauptfragestellung dieser Arbeit. Wir konnten erstmals im Bioassay zeigen, dass kultivierte menschliche Endothelzellen (HUVEC) nach entsprechender Stimulation einen EDHF freisetzen, der Thrombozyten hyperpolarisiert. Weiterhin konnten wir nachweisen, dass dieser Faktor die thrombozytĂ€re AdhĂ€sion an Endothelzellen sowie die thrombozytĂ€re Aktivierung (P-Selektin Expression) hemmte. Diese Effekte waren - analog zu den hyper-polarisierenden Effekten - vermittelt durch Aktivierung von Calcium aktivierbaren Kalium-KanĂ€len (KCa-KanĂ€le) mit großer (BKCa) und mittlerer (IKCa) LeitfĂ€higkeit, nicht jedoch von denen mit geringerer (SKCa) LeitfĂ€higkeit. Die beobachteten Hemmeffekte waren durch die EDHF Wirkungen auf das thrombozytĂ€re Membranpotential erklĂ€rbar, ein zusĂ€tzlicher ergĂ€nzender membranpotentialunabhĂ€ngiger Effekt konnte jedoch nicht ausgeschlossen werden. Der in unserem Bioassay nachweisbare EDHF zeigte Ă€hnliche Eigenschaften wie exogen verabreichte EpoxyeicosatriensĂ€uren (EETs) - Produkte, die durch die Cytochrom P450 2C8/9 Oxidase im Endothel aus ArachidonsĂ€ure gebildet werden. ErhĂ€rtet wurden diese Befunde durch eine CYP2C9 stabil ĂŒberexprimierende Zellinie mit endothelialen Eigenschaften, welche verschiedene EETs in physiologischen Konzen-trationen freisetzte und deren Überstand Ă€hnliche hyperpolarisierende und antiadhĂ€sive Effekte auf Thrombozyten wie der EDHF hatte. EDHF stellte somit unter unseren experimentellen Bedingungen eine Epoxyeicosa-triensĂ€ure (oder eine Mischung verschiedener EETs) dar. Bei vielen Herz-Kreislauf Erkrankungen spielen thrombozytĂ€re Aktivierung und AdhĂ€sion eine wichtige Rolle. Insbesondere beim akuten Herzinfarkt, der Haupttodesursache in westlichen IndustrielĂ€ndern, kommt es in patho-physiologisch, z.B. durch Atherosklerose, vorgeschĂ€digten GefĂ€ĂŸen, aufgrund einer arteriellen Thrombusbildung zum kompletten GefĂ€ĂŸ-verschluss mit MyokardischĂ€mie. Daher könnte EDHF bzw. EET - infolge seiner thrombozytenhyperpolarisierenden und antiadhĂ€siven Effekte - von großer Bedeutung sein, vor allem, wenn er durch Risikofaktoren wie freie Sauerstoffradikale und HyperlipidĂ€mie weniger stark beeinflusst wĂŒrde als NO. Die Daten dieser Dissertation könnten somit zukĂŒnftiger Ansatzpunkt fĂŒr weitere Untersuchungen sowie Basis fĂŒr die Entwicklung potentiell gefĂ€ĂŸprotektiver Medikamente zur effektiveren Therapie kardiovaskulĂ€rer Erkrankungen darstellen

    Propagating Islamic Creationism on the Internet

    Although negative reactions accompanied the reception of Darwinism in the Islamic World from the beginning, a full fledged Islamic creationist movement did notappear before the 1970s. Originally it was restricted to Turkey, where Islamic groups attempted to undermine the materialist foundation of Marxism and Kemalism. From the late 1990s onwards the subject became popular among Muslims inthe diaspora. This was due to the efforts of Adnan Oktar alias Harun Yahya, ahitherto marginal figure in Turkey, to propagate his ideas via the Internet. The Internet allows him to adapt his propaganda constantly to new issues and creationistand anti-creationist publications and to recruit volunteers willing to translate hisbooks. Thanks to the combination of a neglected subject with the innovative use ofnew media Oktar gained the opinion leadership in this field. Even movements, the founders of which had attacked Darwinism, now refer to Oktar as main authorityon this issue. However, he failed to gain an equal degree of attention for topics like conspiracy theories and eschatology. In these fields he had to compete with a bulk ofexisting material in conventional media. The success of his former disciple Mustafa Akyol shows that using the Internet as main means of propaganda may restrict thepolitical impact. He became the chief Muslim ally of Christian creationists in the USA by managing to get published by respectable “old media”. For him the Internet only fulfils an auxiliary function

    Al-Shāáč­ibÄ«s sufismekritik: Hvorfor en ÊżÄlim fra al-Andalus forkastede askese og virtuosereligiositet

    The faqÄ«h (Islamic legal scholar) al-Shāáč­ibÄ« (d. 1388) from Granada is primarily known for his innovative approach within the field of legal theory (uáčŁĆ«l al-fiqh). However, he dedicated much attention to the criticism of sufism. But like other Islamic scholars who opposed Sufism he did not primarily attack infringements on the ‘rights of God’. Instead he highlighted that the ascetic practices propagated by the Sufis are detrimental to the welfare of both the individual Muslim and society as a whole. Furthermore he argues that their charismatic authority based on their asceticism and miracles allegedly bestowed on them threatens to undermine Islamic jurisprudence (fiqh) along rational and intersubjective lines

    General simulation method for quantum-sensing systems

    Full text link
    Quantum sensing encompasses highly promising techniques with diverse applications including noise-reduced imaging, super-resolution microscopy as well as imaging and spectroscopy in challenging spectral ranges. These detection schemes use biphoton correlations to surpass classical limits or transfer information to different spectral ranges. Theoretical analysis is mostly confined to idealized conditions. Therefore, theoretical predictions and experimental results for the performance of quantum-sensing systems often diverge. Here we present a general simulation method that includes experimental imperfections to bridge the gap between theory and experiment. We develop a theoretical approach and demonstrate the capabilities with the simulation of aligned and misaligned quantum-imaging experiments. The results recreate the characteristics of experimental data. We further use the simulation results to improve the obtained images in post-processing. As simulation method for general quantum-sensing systems, this work provides a first step towards powerful simulation tools for interactively exploring the design space and optimizing the experiment's characteristics.Comment: 19 pages, 8 figure
