Recursion
An algorithm that uses the output for one iteration as the input for the next is recursive.
Recursion is behind feedback loops in nature and fractal equations. These concepts are necessary prerequisites to understanding metaculture.
Recursion in Logic
The notion of "meta" is recursion in thought and language. There is literal metacognition, as well as metaphysics, metaethics, and many other fields of self-study.
There is also Gödel's Incompleteness Theorems that use recursive logic to prove the impossibility of a universal proof in mathematics.
Recursion in Video
If you really want recursion in video, point the camera at a TV that is displaying a live feed and gaze in wonder at the fractal pattern it creates.
Or, watch this quick intro on recursion from a coding point of view.
This explanations recursion and how it relates to fractals and the building blocks of nature.
lol math dealer... kinda slaps tho
