Research Methodology. [I cleaned it up for better or worse] From: Farsi, M., Erkoyuncu, J. A., Steenstra, D., & Roy, R. (2019). A Modular Hybrid Simulation Framework for Complex Manufacturing System Design. Simulation Modelling Practice and Theory. I like this model. It looks standard yet it seems to capture all of the parts of doing good research, whether for aircraft engineering or your own. [They are all from “Through-life Engineering Services Centre, School of Aerospace, Transport and Manufacturing, Cranfield University, Cranfield,”]

measuring unit from which all else is derived. ——- The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the ‘quantum of length’, the smallest measurement of length with any meaning. And roughly equal to 1.6 x 10-35 m or about 10-20 times the size of a proton. The Planck time is the time it would take a photon travelling at the speed of light to across a distance equal to the Planck length. This is the ‘quantum of time’, the smallest measurement of time that has any meaning, and is equal to 10-43 seconds. No smaller division of time has any meaning. With in the framework of the laws of physics as we understand them today, we can say only that the universe came into existence when it already had an age of 10-43 seconds.

Synchronization is a particular fascination of mine. I think Phase locked loops creates time, although it’s aberrations *from* PLLs that creates information (for what’s a clock with nothing interesting happening within the gaps?) . But that’s my TimeCube so i try to resist getting too deep.

I’ve wondered for a long time if chaos theory’s intricate and fascinating patterns would ever replace probability clouds. I also always thought uncertainty principle to be a stopgap measure that’s convenient but would someday be replaced by fractals or diffusion patterns or Cantor dust even. Since 1990 I occasionally return to wondering but never stopped to look. Remembering now, I looked and I don’t know if they will, but I’m glad to see work done that can have pragmatic effects as now, unlike 29 years ago, we’re actually ENGINEERING new technologies at those scales and need more precision. https://www.sciencedirect.com/science/article/abs/pii/S0370157318301480
