DESCRIPTION:The Discrete Charm of Geometry\n\nDiscrete geometric structures
  (points\, lines\, triangles\, rectangles\, polygons\, etc.) are ubiquitou
 s in everyday life\, ranging from visible sophisticated freeform structure
 s in contemporary architecture to hidden geometric algorithms in computer 
 generated imagery. On the other hand\, discrete geometric structures have 
 also proven to be very useful in modeling and approximating continuous sha
 pes (e.g. curves and surfaces) and real processes. This lecture provides a
  non-technical and pictorial introduction to the foundations of a new bran
 ch of mathematics which underpins these real world situations.\n	\n	By way o
 f simple and concrete examples\, we will illustrate the paradigm of so-cal
 led structure-preserving discretizations. These include toy spinning tops\
 , elastic rods\, smoke rings and vortex lines in fluids\, conformal textur
 e mappings in computer graphics\, free form glass and steel structures\, a
 nd animations from Hollywood movies. We will also show excerpts from our n
 ew computer-animated movie entitled 'conform!'. This film has won Best Exp
 erimental Short Film at the Berlin Short Film Festival.It will be demonstr
 ated that the difference between the continuous and discrete models in geo
 metry and dynamical systems theory is hardly noticeable.Our aim is to conv
 ince you that this new branch of mathematics is both (literally) beautiful
  and useful.\n
