Mitja Nedic: Spirals - Why are they cool?

Sammanfattning: One can draw an interpolating curve through a discrete set of points in the plane in many different ways. If the set of points has a particular shape, for example a spiral, one would like to find an interpolating curve that reflects the human visual interpolation. In the particular case of spirals, such curves may be obtained from difference equations with the help of infinite products. In this talk, we will show how such a curve may be obtained for a particular spiral called the Theodorus spiral
