Why Is Per Bak Influential?
(Suggest an Edit or Addition)According to Wikipedia, Per Bak was a Danish theoretical physicist who coauthored the 1987 academic paper that coined the term "self-organized criticality." Life and work After receiving his Ph.D. from the Technical University of Denmark in 1974, Bak worked at Brookhaven National Laboratory. He specialized in phase transitions, such as those occurring when an insulator suddenly becomes a conductor or when water freezes. In that context, he also did important work on complicated spatially modulated structures in solids. This research led him to the more general question of how organization emerges from disorder.
