the universe's favorite trick: hiding chaos inside rules so simple a child could write them.
means the quality of being made up of many interconnected parts, so that the whole becomes intricate, tangled, or hard to fully grasp.
from From Latin 'complexus,' the past participle of 'complectere' — to entwine, embrace, or weave together — built from 'com-' (together) and 'plectere' (to plait or braid). The same braiding root threads through 'complex,' 'perplex,' and 'plexus.' So at its heart the word pictures strands woven into a knot — the more threads, the harder to untangle.
