English: Soap Films
{{en%7Cshape of soap bubbles on a geometrical structure}}The shape of a round bubble is only the simplest example of an incredible wealth of shapes that arise with soap films. Imagine a simple experiment with soap films in the kitchen: dip a curved metal wire into a mixture of water and dish-washing detergent, and, when you cautiously pull it out, a soap films forms. With amazing elegance and simplicity, this soap film solves a historic mathematical problem, namely, the soap film finds the least surface area amongst all imaginable surfaces spanned by the wire. Therefore, mathematicians call them "minimal surfaces" since they minimize area……. Two centuries of mathematical research on minimal surfaces is accompanied and determined by the discovery of famous example surfaces. The exhibition of historic minimal surfaces is the first collection of the most influential example http://www.polthier.info/booklet/plateau.html |
