16 Control, OR Comms Compute Physics Shannon Bode Turing Gödel Einstein Heisenberg Carnot Boltzmann Theory? Deep, but fragmented, incoherent, incomplete Nash Von Neumann

17 Control, OR Compute Bode Turing Delay and risk are most important Worst-case (“risk”) Time complexity (delay) Worst-case (“risk”) Delay severely degrades robust performance Computation for control Off-line design On-line implementation Learning and adaptation

18 Control, OR CommunicateCompute Physics Shannon Bode Turing Einstein Heisenberg Carnot Boltzmann Delay and risk are most important Delay and risk are least important

19 Communicate Physics Shannon Einstein Heisenberg Carnot Boltzmann Dominates “high impact science” literature Average case (risk neutral) Random ensembles Asymptotic (infinite delay) Space complexity

20 Control, OR CommunicateCompute Physics Shannon Bode Turing Delay and risk are most important Delay and risk are least important New progress!

26 Wrongness everywhere, every scale, “truthiness” Involving anything “complex”… Wild success: religion, politics, consumerism, … Debates focused away from real issues… Even if erased, sustainability challenges remain Hopeless if it persists I’ll set aside all of this for now, and “zoom in” on the world of PhD research/academic scientists BTW, excellent case study in infectious hijacking Fractal wrongness

27 This paper aims to bridge progress in neuroscience involving sophisticated quantitative analysis of behavior, including the use of robust control, with other relevant conceptual and theoretical frameworks from systems engineering, systems biology, and mathematics. Doyle, Csete, Proc Nat Acad Sci USA, JULY 25 2011 Trivial examples

28 “New sciences” of “complexity” and “networks”? worse Edge of chaos Self-organized criticality Scale-free “networks” Creation “science” Intelligent design Financial engineering Risk management “Merchants of doubt” … Science as Pure fashion Ideology Political Evangelical Nontech trumps tech

29 Complex systems? Fragile Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence … Even small amounts can create bewildering complexity

30 Complex systems? Fragile Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence … Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence … Robust

31 Complex systems? Resources Controlled Organized Structured Extreme Architected … Robust complexity Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence …

32 These words have lost much of their original meaning, and have become essentially meaningless synonyms e.g. nonlinear ≠ not linear Can we recover these words? Idea: make up a new word to mean “I’m confused but don’t want to say that” Then hopefully we can take these words back (e.g. nonlinear = not linear) Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence … Fragile complexity

33 New words Fragile complexity Emergulent Emergulence at the edge of chaocritiplexity Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability Emergence …
