What is 2? (lemmy.blahaj.zone)
submitted 1 month ago* (last edited 1 month ago) by FundMECFSResearch to c/mathmemes

Context:

In ZFC set theory (which most of modern maths is built upon). The natural numbers are defined as recursions of empty sets.

Ie. 0 = ∅ (the empty set)

1 = {∅} = {0}

2 = {∅, {∅}} etc…

And engineering is how you use it in the real world

Engineer: 1.99999 is good enough.

Better just round it to 3 so I can use the π symbol and save space.

[-] sga@lemmings.world 5 points 1 month ago

might as well take a safety factor of 2, so I can use τ, which requires less tie to write than π (I am a engineer)

If it was exactly 2 people would think you were falsifying results.

2 is the successor of 1

holup, what the hell is a "1"? did you mean to say succ(0) by chance?

Mathematics is the art of folding emptiness til it looks like meaning

I am Man I Fold, and thus I Am Math.

In the spirit of Pedanticus the petty till is rotating/plowing soil before planting, until or a shortened 'til is a preposition up to or before something

Statistics is the art of folding emptiness until meaning is found. Mathematics discovers systems that existed before then and after them with no regard for who cares. Those volumes of values are immutable and silent.

0 is the empty set.

1 is the set containing only 0.

2 is the set containing only 1 and 0.
