  1. Universal laws • and architectures: • Theory and lessonsfrombrains, bugs,nets, grids, • docs, planes, fire, fashion, • art, turbulence, music, buildings, • cities, earthquakes, bodies, running,throwing, • Synesthesia, spacecraft, statistical mechanics and zombies John Doyle 道陽 Jean-Lou Chameau Professor Control and Dynamical Systems, EE, & BioE 1 # Ca tech

  2. Fundamentals! • Brains • Nets • Grids (cyberphys) • Bugs (microbes, ants) • Medical physiology • Lots of aerospace • Wildfire ecology • Earthquakes • Physics: • turbulence, • stat mech (QM?) • “Toy”: • Lego • clothing, fashion • Buildings, cities • Synesthesia

  3. Neuroscience + People care + Live demos • Internet (& Cyber-Phys) + Understand the details - Flawed designs - Everything you’ve read is wrong (in science)* • Cell biology (bacteria) + Perfection  Some people care * this comment is for scientists

  4. experiments data theory universals • Neuroscience + People care +Live demos!

  5. Prefrontal Horizontal Meme Transfer Gene Motor Sensory RNA RNAp Learning Software Transcription Striatum Hardware mRNA Amino Acids Reflex Other Control Horizontal App Transfer Ribosomes DNA Translation Digital New gene Proteins Analog Other Control Metabolism Products Horizontal Gene Transfer ATP Signal transduction control feedback

  6. Architecture? Fragile Slow Ideal Fast Inflexible Flexible

  7. Fragile Slow Architecture (constraints that deconstrain) Architecture Impossible (law) Ideal Fast Inflexible Flexible

  8. Universal laws and architectures (Turing) Architecture (constraints that deconstrain) Slow Architecture Impossible (law) Fast ideal Inflexible Flexible Special General

  9. Robust vision with motion • Object motion • Self motion Motion Vision

  10. Layering Feedback Explain this amazing system. Slow Vision Fast Inflexible Flexible

  11. Robust vision with • Hand motion • Head motion • Experiment • Motion/vision control without blurring • Which is easier and faster?

  12. Why? • Mechanism • Tradeoff Slow vision VOR Fast

  13. Mechanism Vestibular Ocular Reflex (VOR) vision Slow Tradeoff VOR Fast Flexible Inflexible

  45. Law #1 : Chemistry Law #2 : Autocatalysis fragile Law #3: 1 10 too fragile complex No tradeoff 0 10 -1 0 1 10 10 10 expensive

  46. I recently found this paper, a rare example of exploring an explicit tradeoff between robustness and efficiency. This seems like an important paper but it is rarely cited.
