A sigma algebra (or σ-algebra) is to set algebras what sigma males are to males. The Borel hierarchy (the analog of the male hierarchy) is not a σ-algebra at any countable rank; instead the σ-algebra has the largest possible rank -- ω_1, the least uncountable ordinal (under suitable conditions e.g. the Polish space is uncountable. This is known as the non-collapse of the Borel hierarchy).
A σ-algebra is closed under countable union, countable intersection, and relative complement. This means σ-algebras arise naturally in the study of measure theory, where the measurable sets form a σ-algebra.

The algebra of Lebesgue-measurable subsets of R (i.e. the sets of real numbers with a well-defined "length", which is possibly infinity) form a sigma algebra.

It is really just another things such as “What the heck” just something to say when something strange happens.

sticking out ur GYATT for the rizzler your so SKIBIDI your so fanon tax I just wanna be your sigma freaking come here and give me your Ohio is a standard used by the very toxic species called Gen-Z and the most dangerous one that needs to be locked in cages is called Gen-alpha

Gen-alpha: STICKING OUR UR GYATT FOR THE RIZZLER-
Non gen-alpha:SHUT THE FUCK UP
