Sigma is the eighteenth letter of the Greek alphabet.
Uppercase sigma (Ξ£) 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 (Ο) 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.
Person 1: Sticking out your gyatt for
the rizzler... I just wanna be your sigma...
Person 2: Erm π€π€π€
technically π€‘π€‘π€‘ your statement implies you want to be the my summation, further implying you want to be a part of my cell receptors π«’π«’π«’ my atomic bonds π€π€π€ and my-
