Das National Institute of Mathematical Sciences (NIMS) stellt in Zusammenarbeit mit dem ICM-Komitee und dem Mathematischen Forschungsinstitut Oberwolfach (MFO) eine besondere IMAGINARY-Ausstellung vor. Gezeigt werden die besten IMAGINARY-Module der letzten Jahre und eine Vielzahl neuer Softwareprogramme, Bilder, Filme und Skulpturen. Es handelt sich um die bislang größte IMAGINARY-Ausstellung.

Die Stiftung Heidelberg Laureate Forum Foundation lädt Sie vom 5. Juli bis 2. August 2015 im Karlstorbahnhof Heidelberg ein, die Ausstellung „Mathematik des Planeten Erde“ zu besuchen. Die Ausstellung ist zum ersten Mal in Heidelberg und verspricht für Jung und Alt ein abwechslungsreiches und spannendes Erlebnis.
Circular shaped mirrors which are arranged in a grid-like manner reflect a light ray according to the reflection law of geometric optics. While random positions of the light source produce chaotic reflection patterns, it is possible to position the light source so that beautiful symmetric reflection patterns are created.
The application allows you to interactively change parameters like light source position, circle radius and rotation angle of the lattice. Through a simple menu it is possible to select and explore a wide range of symmetric reflection patterns.

All images in this gallery are made with the open source software FroZenLight available at http://frozenlight. altervista.org
The software casts a light ray onto a grid of circular shaped mirrors and calculates all subsequent reflections by the law of geometric optics (the wave like nature of light is omitted). This simple model is very chaotic as errors of the position of the light source quickly blow up and indeed arbitrary precision math is needed to calculate most of reflection patterns.
The images in this gallery show symmetric reflection patterns emerging at special positions of the light source and special rotations of the mirroring lattice. Observe that the ray that leaves the light source (small triangle) enters the light source exactly at the same height on the backside.
The FroZenLight application is highly interactive and comes with a lot of predefined patterns.

A main feature of the simple circle lattice model is that all reflection patterns depend sensibly on the given parameters meaning that the slightest change has a dramatic impact. Long numbers are therefore needed to reveal the intrinsic beauty of the model (see FroZenLight gallery).
Math exercises with solutions and further documentation are provided at the homepage.
