Diskrete Differentialgeometrie-operatoren Auf Triangulierten Mannigfaltigkeiten

In dieser Arbeit geht es darum wichtige geometrische Eigenschaften wie z.B. die Krümmung auf beliebigen triangulierten Gittern zu diskretisieren. Dazu wird ein allgemeines Vorgehen zur Diskretisierung der Operatoren vorgestellt, bei dem die Durchschnittsbildung von Voronoi Zellen und die gemischten Finite Elemente und Finite Volumen Methoden verwendet werden. Diese Methode wenden wir dann an, u...

The Rand Myth

Many people believe that Objectivism is simply a movement composed of selfish, deranged, arrogant anti-environmentalists. They are right. The fact is, Objectivists care little for their fellow man and less for the facts. The staple of Objectivism is not science, but hollow pseudo-philosophic anti-intellectual claptrap and outright lies. All designed to trick well meaning people into accepting a...

Deconstructing RAND : Education Next

In the summer of 2000, perfectly timed to shape the election debate over education reform, came a new RAND study that claimed to contradict the conventional research wisdom on the connection between school expenditures and class size on the one hand and student achievement on the other. “Our results certainly challenge the traditional view of public education as ‘unreformable,’” the study’s dir...
