Werner Fischer (crystallographer)
Werner Fischer (born February 8, 1931, in Gablonz an der Neiße, Gablonz an der Neisse, Czechoslovakia) is a German mineralogist and mathematical crystallographer. Education and life Fischer passed his Abitur in 1951 in Kappeln, Kappeln an der Schlei. Supported by the German National Academic Foundation, he studied at University of Stuttgart and Kiel University, University of Kiel. There he also received his doctorate in 1959 with a thesis on structural studies on synthetic carnallite. In 1970 he habilitated at Philipps-University Marburg with a thesis on homogeneous packing of spheres and their conditions of existence in space groups of tetragonal symmetry. In 1971 he was appointed professor. From 1974 to 1978 he worked at the University of Münster and then worked at the Philipps-University Marburg until his retirement in 1996. Fischer's research dealt with mathematical crystallography, in particular with periodic Minimal surface, minimal surfaces, Sphere packing, sphere pack ...

Gablonz An Der Neiße
Jablonec nad Nisou (; german: Gablonz an der Neiße) is a city in the Liberec Region of the Czech Republic. It has about 45,000 inhabitants. It is the second-largest city in the region. It is a local centre for education, and is known for its glass and jewelry production. The town centre is well preserved and is protected by law as an Cultural monument (Czech Republic)#Monument zones, urban monument zone. Administrative parts Jablonec nad Nisou is made up by eight city parts: Jablonec nad Nisou, Jablonecké Paseky, Kokonín, Lukášov, Mšeno nad Nisou, Proseč nad Nisou, Rýnovice and Vrkoslavice. Etymology The name ''Jablonec'' is of Czech language, Czech origin and means ''"little apple tree"'' (''jablonče'' was a diminutive of the old Czech ''jabloň'' – "apple tree"), for the village was founded on a place where an apple tree grew. German-speaking settlers who came to the village during the 16th century adjusted the name to ''Gablonz''. During the 19th century, the attribut ...

Sphere Packing
In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or hypersphere packing in higher dimensions) or to non-Euclidean spaces such as hyperbolic space. A typical sphere packing problem is to find an arrangement in which the spheres fill as much of the space as possible. The proportion of space filled by the spheres is called the ''packing density'' of the arrangement. As the local density of a packing in an infinite space can vary depending on the volume over which it is measured, the problem is usually to maximise the average or asymptotic density, measured over a large enough volume. For equal spheres in three dimensions, the densest packing uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Stuttgart Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Academic Staff Of The University Of Münster
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German Crystallographic Society
The German Crystallographic Society (''Deutsche Gesellschaft für Kristallographie'', or DGK in German) is a non-profit organization based in Berlin. As a voluntary association of scientists working in crystallography or interested in crystallography and other people and institutions, its goal is to promote crystallography in teaching, research and industrial practice as well as in the public, in particular by fostering the exchange of experience and ideas as well as further education at national and international level Frame. Working groups are dedicated to specific areas of crystallography. The Society has just over 1000 members. Activities The DGK represents crystallography in national and international scientific institutions. In particular, the DGK is a member body of the International Union of Crystallography (IUCr) and the European Crystallographic Association (ECA). The DGK nominates candidates for the crystallographically relevant review boards of the German Research Foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Tables For Crystallography
The International Union of Crystallography (IUCr) is an organisation devoted to the international promotion and coordination of the science of crystallography. The IUCr is a member of the International Council for Science (ICSU). Objectives The objectives of the IUCr are to promote international cooperation in crystallography and to contribute to all aspects of crystallography, to promote international publication of crystallographic research, to facilitate standardization of methods, units, nomenclatures and symbols, and to form a focus for the relations of crystallography to other sciences. The IUCr fulfils these objectives by publishing in print and electronically primary scientific journals through the '' Acta Crystallographica'' journal series, as well as '' Journal of Applied Crystallography'', ''Journal of Synchrotron Radiation'', ''IUCrJ'', the series of reference volumes ''International Tables for Crystallography'', distributing the quarterly ''IUCr Newsletter'', main ...
