The mathematical equations that describe complex physical systems can in many cases not be solved exactly, but most often it is not an obstacle for physicists. Many such problems can be solved numerically using modern computers. SDU hosts one of the strongest supercomputers in the country, Abacus 2.0, and it is used as a tool for research on a wide range of subjects, from particle physics to advanced materials to stellar evolution. For example, computer models can be used to study how a material has different properties at different temperatures. One cannot see from the individual atoms that a material is crystallized, for example, but only by regarding the whole. It is an example of one of many so-called emergenic phenomena that can be investigated with computer simulations.
