Sigma is the eighteenth letter of the Greek alphabet.
Uppercase sigma (Σ) is used in Sigma Notation, also known as summation notation in mathematics. It represents the addition of a sequence, and this sequence can be derived from values given by a function, values in a set, values present in a Free-Body Diagram, etc.
Lowercase sigma (σ) represents many things across all sciences. Notably, it represents the Stefan-Boltzmann constant, a constant used in the Stefan-Boltzmann law of radiation. In chemistry, sigma bonds are a type of bond characterized by overlapping p-orbitals. In quantum mechanics, sigma represents Pauli matrices. In biology, sigma receptors are poorly understood cell receptors that bond to certain stimulants like cocaine, meth, and other drugs.

Get the Sigmamug. A short man, likely with a Napoloeon complex. This type of man is either a toddler on Youtube shorts or a middle aged, balding man who has mommy issues and multiple divorces under his massive belt.
