Pillar 5: NUMBER AND PATTERN
[144:1] "A function is a machine that takes input and produces
output."
[144:2] --- Informal mathematical definition
[144:3] "The universe computes itself through functions."
[144:4] --- Computational metaphysics
[144:5] "f(x) is the archetype of process."
[144:6] --- Mathematical philosophy
[144:7] [144:1] A function is a relationship that maps input to
output---a rule that, given something, produces something else, reliably
and consistently.
[144:8] [144:2] "A machine that takes input and produces
output." This informal definition captures the function's essence. Put
in x, get out f(x). The function transforms; it doesn't merely store.
It is dynamic where the equation is static; it is process where the
equation is relation.
[144:9] [144:3] Functions are everywhere. The position of a
planet is a function of time. The price of a stock is a function of many
variables. Your mood is a function of sleep, nutrition, relationships.
To understand the world is to understand its functions---what produces
what from what.
[144:10] [144:4] "The universe computes itself through
functions." This is the computational view: reality is not made of
stuff but of transformations; not of nouns but of verbs; not of things
but of processes. The function is the formal model of process; if the
universe is process, the universe is functional.
[144:11] [FIGURE 144.1: A function as black box---input arrow
entering, output arrow exiting, the function (f) transforming inside.]
[144:5] "f(x) is the archetype of process." The notation f(x) says:
there is a process (f), there is an input (x), there is an output
(f(x)). This minimal structure contains the logic of causation, of
creation, of change. The Omni Function (Gate 4) is f(x) where f is Love
and x is Consciousness.
[144:12] [144:6] Functions compose. If f transforms x to y, and
g transforms y to z, then g(f(x)) transforms x to z. Functions chain;
complex processes build from simple ones. The composability of functions
mirrors the composability of the universe---complexity from simplicity.
[144:13] [144:7] Not all relationships are functions. A function
must give exactly one output for each input. If the same input could
produce different outputs, it's not a function---it's a relation. The
determinism of functions (same input → same output) mirrors the
lawfulness of nature.
[144:14] [144:8] Inverse functions undo what functions do. If f
transforms x to y, then fâ»Â¹ transforms y back to x. Not all functions
have inverses (information can be lost in the transformation). Where
inverses exist, processes are reversible; where they don't, time has a
direction.
[144:15] [144:9] Higher-order functions take functions as input
or produce functions as output. This is abstraction upon
abstraction---not just transforming values but transforming
transformations. The mind that understands higher-order functions is a
mind that has climbed a ladder of abstraction.
[144:16] [144:10] You are a function. You take inputs (food,
experience, love) and produce outputs (action, creation, love returned).
The pattern of your transformation---your personal function---is your
character. What function are you? What do you transform into what?
