  1. The problem of Fractal Wrongness • Great work built on weak foundation (science) • Hope I can learn and help (shake things up)

  2. Fractal wrongness Emergence Risk

  3. Fractal wrongness Emergence Risk Sustainability Autocatalysis Global !#%&!?!? Evolution Technology Markets, finance, … … Robustness Efficiency Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability … Much (most?) of what many (most?) believe is obviously false.

  4. Fractal wrongness • 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

  5. Fractal wrongness (PhDs only) Emergence Risk Sustainability Autocatalysis Global !#%&!?!? Evolution Technology Markets, finance, … … Robustness Efficiency Scale Dynamics Nonlinearity Nonequlibrium Open Feedback Adaptation Intractability … Much (most?) of what many (most?) believe is obviously false.

  7. Fractal wrongness (PhDs only) • “Wrongness” everywhere, every scale • Involving “complexity” • Wild success: high impact journals, funding agencies, popular science, policy… • Debates shifted away from real issues… • Even if erased, huge challenges remain • Hopeless if it persists? • BTW, excellent case study in infectious hijacking

Fractal wrongness (PhDs only) • “Wrongness” everywhere, every scale • Involving “complexity” • Wild success: high impact journals, funding agencies, popular science, policy… • Debates shifted away from real issues… • Even if erased, huge challenges remain • Hopeless if it persists? • I’ll set this aside for now, and “zoom in” to a small spot (within science) with a solid foundation (but a huge spot in math and engineering)

  10. A source of fractal wrongness we need to remove Large, thin, nonconvex

  11. “solution sets” (a la Marder, Prinze, etc) large, thin, nonconvex Software Hardware Functional Digital Analog All systems

  12. Layered language? Meaning Syntax Words Letters large, thin, nonconvex

  13. Letters and words • 9 letters: adeginorz • 9!= 362,880 sequences of 9 letters • Only “organized” is a word • << (# words) << (# non-words) large thin Meaning Syntax Words Letters

  14. Language? Almost all • grammatical sentences are meaningless • sequences of words are ungrammatical • sequences of letters are not words • collections of symbols are not letters Meaning Syntax Words Letters

  15. Almost all • grammatical sentences are meaningless • sequences of words are ungrammatical • sequences of letters are not words • collections of symbols are not letters • large, thin, nonconvex • # of order parameters  • with  tuning, Watson beat humans at Jeopardy • What are the protocols and architecture? Meaning Syntax Words Letters

  16. large thin 1 << # toys << # piles toys pile

  17. large thin 1 << # toys << # piles emergence edge of chaos self-organized criticality scale-free ??? pile statistical physics random ensembles minimally tuned phase transitions bifurcations “order for free?”

  18. large thin 1 << # toys << # piles nonconvex toys pile “order for free?”

  19. Computer programs Software • Almost any computer language • Large # of working programs •  larger # of non-programs • “Nonconvex” = simple mashups of working programs don’t work • Need architecture to organize working programs • << (# programs) << (# non-programs) large thin Hardware Digital Analog

  20. Computer programs Software Software is not an emergent property of hardware • morphodynamics and “top-down causality” ? • teleodynamics? Hardware Digital Analog

  21. functional software Meaning Software Syntax Hardware All “code” large, thin, nonconvex Words Digital Letters Analog digital Analog

  22. 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. Trivial examples Doyle, Csete, Proc Nat AcadSci USA, JULY 25 2011

  23. Universal “laws” (constraints) • Some constraints on bio & tech rise “bottom up” from physics/chemistry • Gravity • Speed of light • Energy • Carbon • Other small moieties (e.g. redox, …)… more later? • Emergence?

  24. Physical laws as constraints on components • Gravity • Speed of light • Energy • Carbon • Other small moieties (e.g. redox, …)… more later Components

  25. Biology & technology not emergent in any useful sense • Dissipation, friction • Liquids, gases, fluid dynamics • Phase transitions, homogeneous turbulence, etc • etc etc Huge gap Emergent phenomena? Components

  26. Risk not emergent in any useful sense? Gap? Biology & technology not emergent in any useful sense Huge gap • Dissipation, friction • Liquids, gases, fluid dynamics • Phase transitions • etc etc Emergent phenomena? Components

  27. Risk not emergent in any useful sense? Gap? Biology & technology not emergent in any useful sense Huge gap • Dissipation, friction • Liquids, gases, fluid dynamics • Phase transitions • etc etc Emergent phenomena? Components

  28. Teleodynamics (Deacon) HUGE gap Top down causality (Juarrero) Morphodynamics (Deacon) Big gap Emergent phenomena? Components

  29. Active Passive Turbulent Laminar Lumped  coherent story here, but haven’t figured out best way to explain… working on it… fragile Passive Distribute Laminar Lossless Classical Needs active Quantum ? robust Turbulent efficient wasteful

  30. Emergence?

  31. “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

  32. Theorem! z and p functions of enzyme complexity and amount Fragility simple enzyme complex enzyme Enzyme amount Savageaumics

  33. Fragility hard limits • General • Rigorous • First principle simple complex ? Overhead, waste • Domain specific • Ad hoc • Phenomenological Plugging in domain details

  34. Control Wiener Comms Bode Shannon robust control Kalman • Fundamental multiscale physics • Foundations, origins of • noise • dissipation • amplification • catalysis • General • Rigorous • First principle ? Carnot Boltzmann Heisenberg Physics

  35. What I’m not going to talk much about • It’s true that most “really smart scientists” think almost everything in these talks is nonsense • Why they think this • Why they are wrong • Time (not space) is our problem, as usual • Don’t have enough time for what is true, so have to limit discussion of what isn’t • No one ever changes a made up mind (almost) • But here’s the overall landscape

  37. Popular but wrong

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

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

  41. 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
