messiness

Non Linearity, Complexity Theory, Complex Adaptive Systems, Complex System-s

Bob Frankston: *Complexity is a measure of the degree to of our inability to Model a system.* (in other words, it's just another way of saying "i dunno")

Wiley's Complexity Journal is *not meant to serve as a forum for speculation and vague analogies between words like "chaos (Chaos Theory)," "SelfOrganization," and "Emergence" that are often used in completely different ways in science and in daily life.*

The theme of the Complexity International Jounal is *the field of Complex Systems, the generation of complex behaviour from the interaction of multiple parallel processes.*

Cosma Shalizi says *A definition would be nice. So would an ordinal if not a cardinal measure... The "sciences of complexity" are very much a potpourri, and while the name has some justification --- chaotic motion seems more complicated than harmonic oscillation, for instance --- I think the fact that it is more dignified than "neat nonlinear nonsense" has not been the least reason for its success. --- That opinion wasn't exactly changed by working at the Santa Fe Institute for five years.*
