Gestern hab ich etwa die ersten zwölf Kapitel Nikolaus von Cusas "docta ignorantia" in lateinischer Fassung und deutscher Übersetzung verglichen. Dabei entdeckte ich dass die Übersetzer systematisch wesentliche Teile des Originals ausgelassen haben, ob weil diese ihnen überflüssig, vielleicht sinnlos oder unverständlich erschienen ist mir nicht klar. Jedoch klar ist mir die dialektische Bedeutung des Namens. Es handelt sich tatsächlich um docta ignorantia, wenn diese als gelehrter Unfug oder gelehrte Unwissenheit bezeichnet wird, oder auch als unwissende Gelehrsamkeit. In jedem Fall ist es Scholastik die beansprucht der Sprache, den Worten, ein umfassendes Erleben abzugewinnen. Die beiden willkürlich ausgesuchten Beispiele zeitgenössischer Forschung die ich nachstehend zitiere, mögen als Vorlage, als Schablone für mein Verstehen der zeitgenössischen Wissenschaft dienen. Ich frage: In wie weit ist auch sie Scholastik? Wenn Scholastik, dann wäre diese Scholastik die sich so ausdrücklich auf Beobachten und Experimentieren behauptet, anders als die Wortklaubereien des Mittelalters? Die zeitgenössische Wissenschaft bedarf viel weiteren Bedenkens. "We study the linear polarization from the accretion disk around a class of static traversable wormholes. Applying the simplified model of a magnetized fluid ring orbiting in the equatorial plane, we search for characteristic signatures, which could distinguish wormhole from black hole spacetimes by their polarization properties. For the purpose we analyze the direct polarized images for different inclination angles, the strongly lensed indirect images, and the polarized radiation which reaches the asymptotic observer through the wormhole throat, and compare to the Schwarzschild black hole. For small inclination angles the two types of compact objects lead to a very similar polarization pattern of the direct images. More significant distinctions are observed for the strongly lensed indirect images, where the polarization intensity in the wormhole spacetimes can grow up to an order of magnitude compared to the Schwarzschild black hole. Detecting radiation from the region across the wormhole throat leads to the formation of an additional structure of ring images with distinct polarization properties. The twist of the polarization vector around the ring is less pronounced, thus modifying the polarization pattern, and the polarization intensity can increase with an order of magnitude compared to the radiation from our Universe. Thus, while it could be difficult to distinguish wormhole spacetimes by their direct polarized images, the strongly lensed images and the polarization of the radiation through the wormhole throat provide characteristic signatures which can serve as probes for horizonless objects. November 24, 2022 Webb telescope reveals blazing hourglass around forming star The colourful clouds are only visible in infrared light, so had never been seen before being captured by the James Webb Space Telescope. The James Webb Space Telescope unveiled its latest image of celestial majesty on Wednesday, an ethereal hourglass of orange and blue dust being shot out from a newly forming star at its center. The colorful clouds are only visible in infrared light, so had never been seen before being captured by Webb's Near-Infrared Camera (NIRCam), NASA and the European Space Agency said in a statement. The very young star, known as protostar L1527, is hidden in darkness by the edge of a rotating disk of gas at the neck of the hourglass. However light spills out from the top and bottom of the disk, lighting up the hourglass-shaped clouds. The clouds are created by material ejected from the star colliding with surrounding matter, the statement said. The dust is thinnest in the blue sections and thickest in the orange parts, it added. The protostar, which is just 100,000 years old and at the earliest stage of star formation, is not yet able to generate its own energy. The surrounding black disk, which is around the size of our solar system, will feed material to the protostar until it eventually reaches "the threshold for nuclear fusion to begin," the statement said. "Ultimately, this view of L1527 provides a window into what our Sun and solar system looked like in their infancy," it added. This video zooms in towards the protostar L152 to reveal the object as seen by the NASA/ESA/CSA James Webb Space Telescope, embedded within a cloud of material that is feeding its growth. Material ejected from the star has cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. The upper central region displays bubble-like shapes due to stellar 'burps,' or sporadic ejections. Webb also detects filaments made of molecular hydrogen that has been shocked by past stellar ejections. Intriguingly, the edges of the cavities at upper left and lower right appear straight, while the boundaries at upper right and lower left are curved. The region at lower right appears blue, as there's less dust between it and Webb than the orange regions above it. Credit: ESA/Webb, NASA, CSA, unWISE/JPL-Caltech/D. Lang (Perimeter Institute), E. Slawik, N. Risinger, N. Bartmann, M. Zamani Music: Tonelabs—The Red North (www.tonelabs.com) The protostar is located in the Taurus molecular cloud, a stellar nursery home to hundreds of nearly formed stars around 430 light years from Earth. Operational since July, Webb is the most powerful space telescope ever built, and has already unleashed a raft of unprecedented data as well as stunning images. Scientists are hopeful it will herald a new era of discovery. One of the main goals for the $10-billion telescope is to study the life cycle of stars. Another main research focus is on exoplanets, planets outside Earth's solar system. © 2022 AFP Journal Article Galaxy And Mass Assembly (GAMA): extended intragroup light in a group at z = 0.2 from deep Hyper Suprime-Cam images Get access Arrow Cristina Martínez-Lombilla, Sarah Brough, Mireia Montes, Roberto Baena-Gallé, Mohammad Akhlaghi, Raúl Infante-Sainz, Simon P Driver, Benne W Holwerda, Kevin A Pimbblet, Aaron S G Robotham Monthly Notices of the Royal Astronomical Society, Volume 518, Issue 1, January 2023, Pages 1195–1213, https://doi.org/10.1093/mnras/stac3119 Published: 24 November 2022 ABSTRACT We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxies. We examine the intragroup light (IGL) of the group 400138 (Mdyn = 1.3 ± 0.5 × 1013 M⊙, z ∼ 0.2) from the Galaxy And Mass Assembly (GAMA) survey using Hyper Suprime-Cam Subaru Strategic Program Public Data Release 2 (HSC-SSP PDR2) images in g, r, and i bands. We present the most extended IGL measurement to date, reaching down to μlimg=30.76  mag arcsec−2 (3σ; 10 × 10 arcsec2) at a semimajor axis of 275 kpc. The IGL shows mean colour values of g − i = 0.92, g − r = 0.60, and r − i = 0.32 (±0.01). The IGL stellar populations are younger (2–2.5 Gyr) and less metal rich ([Fe/H] ∼ −0.4) than those of the host group galaxies. We find a range of IGL fractions as a function of total group luminosity of ∼2−36 per cent depending on the definition of IGL, with larger fractions the bluer the observation wavelength. The early-type to late-type galaxy ratio suggests that 400138 is a more evolved group, dominated by early-type galaxies, and the IGL fraction agrees with that of other similarly evolved groups. These results are consistent with tidal stripping of the outer parts of Milky Way-like galaxies as the main driver of the IGL build-up. This is supported by the detection of substructure in the IGL towards the galaxy member 1660615 suggesting a recent interaction (<1 Gyr ago) of that galaxy with the core of the group. Ich komme zurück zu meiner ursprünglichen Vermutung, dass mir der Vorgang und die Ergebnisse der naturwissenschaftlichen Forschungen als Ausdruck nicht der Natur, sondern des Gemüts vor allem des gesellschaftlichen Gemüts verständlich wird. Der "Erfolg", der Ruhm des Einzelnen als Wissenschaftler ist ein gesellschaftliches Phänomen.
