The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. [2] [3] It was derived from the earlier Phoenician alphabet, [4] and is the earliest known alphabetic script to systematically write vowels as well as consonants. [5]
the thermodynamic beta, equal to (k B T) −1, where k B is the Boltzmann constant and T is the absolute temperature. the second angle in a triangle , opposite the side b the standardized regression coefficient for predictor or independent variables in linear regression (unstandardized regression coefficients are represented with the lower-case ...
Alpha / ˈ æ l f ə / [1] (uppercase Α, lowercase α) [a] is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph, which is the West Semitic word for "ox". [2] Letters that arose from alpha include the Latin letter A and the Cyrillic letter А.
Beta male, or simply beta, is a slang term for men derived from the designation for beta animals in ethology, along with its counterpart, alpha male. [ 8 ] [ 9 ] The term has been used as a pejorative self-identifier among members of manosphere communities, particularly incels , who do not believe they are assertive or traditionally masculine ...

In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or (0, 1) in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the variable and its complement to 1, respectively, and control the shape of the distribution.

In two dimensions, the Levi-Civita symbol is defined by: = {+ (,) = (,) (,) = (,) = The values can be arranged into a 2 × 2 antisymmetric matrix: = (). Use of the two-dimensional symbol is common in condensed matter, and in certain specialized high-energy topics like supersymmetry [1] and twistor theory, [2] where it appears in the context of 2-spinors.
