I’m an electrical engineer by training. In my first circuits class, all calculations were done by hand, and we could check solutions with unintuitive circuit simulators using the SPICE methodology. With SystemModeler I think it’s easier than ever to get started building virtual circuits and trying what-if scenarios for electrical circuits and systems. In this [...]

9:07 AM | Minimal Surfaces

Minimal surfaces are mathematical surfaces with minimal surface area. To get an idea of these surfaces think of soap bubbles. Giving them a framework soap films create the minimal surface within this frame. Here we want to show some models and illustrations of minimal surfaces for different frames. We thank Paul Nylander for letting us use these pictures.

6:09 PM | Beweis der Kepler Vermutung erfolgt

Mehr als 400 Jahre nachdem die sogenannte „Keplersche Vermutung“ aufgestellt wurde, liegt nun offenbar ein vollständiger, formaler Beweis vor. Die Mathematik hat dabei wiedereinmal besondere Wege beschritten. Kepler selbst stellte seine Vermutung 1611 auf, konnte sie aber nie beweisen. Thomas Hales hat bereits 1998 eine erste Lösung vorgestellt, die allerdings „nur“ auf massiven Computerberechnungen basierte.2003 begann Hales damit, seinen Beweis zu Formalisieren – und scheint […]
