Complex Systems includes the science, mathematics and engineering of systems with simple components but complex overall behavior. This year’s Nobel Prize in Physics was awarded "for groundbreaking contributions to our understanding of complex systems" with one half jointly to Syukuro Manabe and Klaus Hasselmann "for the physical modelling of Earth's climate, quantifying variability and reliably predicting global warming" and the other half to Giorgio Parisi "for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales." Research topics cover a broad spectrum of physical and engineering complex systems. Specific examples, but not limited to, are non-linear dynamical systems, condensed matter glasses, polymers, colloids, super-cooled liquids, fragile molecular glasses, and even the social sciences.
