Background:
Over the past several years my friends and I would get together for music nights where we share albums and songs we've been listening to. We also have a projector in case we want to showcase music videos.
Eventually, I made us a music visualizer that analyzes real-time microphone input and draws various geometries on to the screen, giving us something to engage our eyes. I built it using the Processing library for Java.
I had to track my physical inputs and outputs for a week for medical reasons and I used a google form. I placed a shortcut on my phone and it immediately opened the form for simple and easy tracking. Everything was then saved to a spreadsheet, which I could analyze once my week was done.
I can't think of physical processes that could go from macro -> micro. The examples I can think of stem from Yuval Harari's human fictions affecting the world. For example, a nation state or a corporation or a story could set the stage for the macro affecting the micro. If we look at a story, it communicates an idea that changes the behaviors of humans, which in turn causes those humans to interact with the micro and the macro.
As I'm writing this out and thinking about it, where would fictional objects fit on the micro <--> macro axis?
Reading your comment made me wonder why we have even numbers of limbs for different body plans. I realized it's due to bilateral symmetry for most organisms must some how be advantageous to asymmetric body plans, but I'm unsure how symmetry is advantageous. What are the evolutionary pressures selecting against asymmetric body plans?
