Riassunto
In this exciting and rapid development reflecting book twelve of the participants at the Symposium "From Simple Material Systems to Complex Ones" - "From Information to Structure" give a general view of todays knowledge with respect to multi-, inter- and transdisciplinary research in chemistry and science in general. How to analyse e. g. non-covalent interactions in the case of molecular recognitions or selfreplication, how to build up e. g. clusters and self-assembled molecules or how, in general, a knowledge of simple systems, acquired by the instruments of natural science research can be transferred to (more) complex systems and be utilized to improve our understanding, even of society was discussed by experts on chemical subjects like biochemistry, structure analysis, supramolecular chemistry and cluster formation up to biophysics, social sciences and philosophy.
