I read this article more because I'm interested in Zen than QM. But it prompted a question for me. What (if any) is the relationship between QM (which I understand to manifest mainly at the level of particles and very small scales) and the science of complex non-linear dynamic systems (colloquially "chaos theory"). Both centre around the philosophical concept of unknowability, unpredictability, uncertainty. Both prompt questions around why the world is the way it is, rather than any of the other states it could have ended up in, which leads to wondering about whether alternate states could, or should, also exist. I personally find complexity more approachable, as it concerns phenomena that are at a more relatable scale - the weather, the economy, species evolution etc. Is there any intersection between QM and complex systems science in the conventional/institutional sense, e.g. in study or research? Or are they separate rabbit holes?
