The quiet revolution: When complex left networks

Soon after networks became all the rage among statistical physicists, the field turned away from the home turf of complex systems science. This blog post argues for considering network science as distinct from complexity science. All is sketchy and subjective (from the viewpoint of a statistical physicist jumping on the complex-networks bandwagon). I can think […]

Faraway, so close! Nobel prize to complex systems

Yesterday, it was announced that Syukuro Manabe, Klaus Hasselmann, and Giorgio Parisi get to share the 2021 Nobel prize in physics. Woo hoo! I had a smile on my lips running through the night streets of Tokyo (my usual exercise). The best part is the motivation: “For groundbreaking contributions to our understanding of complex physical […]

Universality: Stronger than logic

I was re-reading some old universality papers. You know, universality in the stat-mech sense—the critical exponents that characterize phase transitions are insensitive to details of your model or crystal structure of your material. This insight matured in the 1950s and 60s and culminated with Kenneth Wilson’s development of the renormalization group in the first few […]
