Get the algebra mug.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.

Get the Algebra mug.A derogatory term used against people with slower brain development. People who are called algebra students are most likely slower in the brain or just “dumb”. If you are still in algebra today you are one of the very small minority of people still doing it.

Get the Algebra 2 mug.When letters go into math, boring middle and high schoolers out of their mind. In fact, you aren't doing this class's homework currently because you are too busy procrastinating on the urban dictionary searching up this word.
