Abstract math Memes

When you ask a mathematician "how many elements are in this set?" and they show you a fractal nightmare of nested sets within sets within sets, then casually say "4" like they didn't just make you question reality. The curly brace notation at the top reads {{},{{},{{},{{}}}}}, which is literally just mathematicians counting to 4 using the empty set and pure spite. This is how set theory builds natural numbers from nothing—starting with the empty set {} and recursively nesting them. It's beautiful, horrifying, and completely unnecessary for buying groceries, yet here we are.
