NASA Supermassive-Black-Hole Gravity Discovery: "Confirms Einstein's Theory of Space-Time" Two X-ray space observatories, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton , have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our sun that lies at the dust- and gas-filled heart of a galaxy called NGC 1365 (image above). Measuring the spin of a supermassive black hole is fundamental to understanding its past history and that of its host galaxy. The observations are a powerful test of Einstein's theory of general relativity, which says gravity can bend space-time, the fabric that shapes our universe, and the light that travels through it. The supermassive black hole is spinning almost as fast as Einstein's theory of gravity will allow. NuSTAR, an Explorer-class mission launched in June 2012, is designed to detect the highest-energy X-ray light in great detail. For more information on ESA's XMM-Newton mission, visit:

The Open Problems Project Next: Numerical List of All The Open Problems Project edited by Erik D. Demaine Joseph S. Joseph O'Rourke Introduction This is the beginning of a project1 to record open problems of interest to researchers in computational geometry and related fields. Each problem is assigned a unique number for citation purposes. The problems are also available as a single Postscript or PDF file. To begin navigating through the open problems, you may select from a category of interest below, or view a list of all problems sorted numerically. Categorized List of All Problems Below, each category lists the problems that are classified under that category. arrangements: 3-Colorability of Arrangements of Great Circles (Problem 44) art galleries: Vertex π-Floodlights (Problem 23) coloring: combinatorial geometry: convex hulls: data structures: Delaunay triangulations: dissections: Congruent Partitions of Polygons (Problem 73) folding and unfolding: geometric graphs: graph drawing: graphs: linear programming: lower bounds: meshing:

Die Schöne Ebstorferin DIE SCHÖNE EBSTORFERIN von Michael Zick Die 700 Jahre alte Karte ist das größte mittelalterliche Welt-Bild. Forscher haben das seltene Stück aus dem Kloster Ebstorf rekonstruiert – einen zeittypischen Mix aus Kartografie und Mythologie. „Wer zum Paradies will, benötigt eine Leiter und muss darauf rund drei Meter hoch klettern. Die Leiter benötigt der Paradies-Sucher im Ebstorfer Kloster in der Lüneburger Heide, um die 3,58 mal 3,56 Meter messende „Ebstorfer Weltkarte“ betrachten zu können. Aus der wechselvollen Geschichte der ‚Schönen Ebstorferin’ Die Geschichte beginnt 1830, als im Ebstorfer Kloster Großreinemachen angesagt ist. Doch kaum aus der schützenden Dunkelkammer ans Licht geholt, beginnt der Zerstörungsprozess: Ein Unbekannter schneidet ein 66 mal 50 Zentimeter großes Stück heraus. 1891 wurde eine fotografische Reproduktion in Schwarz-Weiß angefertigt. 1930 schließlich entstand aus den Lichtdrucktafeln Sommerbrodts eine große Rollkarte, die mit Temperafarben übermalt wurde.
