Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
Symbol Name Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian
It is common, especially in engineering applications, to represent the specific gas constant by the symbol R. In such cases, the universal gas constant is usually given a different symbol such as R to distinguish it. In any case, the context and/or unit of the gas constant should make it clear as to whether the universal or specific gas ...
the population mean or expected value in probability and statistics; a measure in measure theory; micro-, an SI prefix denoting 10 −6 (one millionth) Micrometre or micron (retired in 1967 as a standalone symbol, replaced by "μm" using the standard SI meaning) the coefficient of friction in physics; the service rate in queueing theory
Dorsai! is the first published book of the incomplete Childe Cycle series of science fiction novels by American writer Gordon R. Dickson. Later books are set both before and after the events in Dorsai!. The novel was originally published in serialized form in Astounding Science Fiction, starting in May 1959.
The Kemlo books are a series of children's science fiction novels written by Reginald Alec Martin, under the pseudonym of E. C. Eliott. [1] The first book, Kemlo and the Crazy Planet was published in 1954; the fifteenth and final book in the series, Kemlo and the Masters of Space, was published in 1963.
together with a degree symbol (°), the Celsius measurement of temperature = °C [10] the circumference of a circle or other closed curve; with a subscript, a cycle on that many vertices; with a subscript, a cyclic group of that order; the complement of a set (lowercase c and the symbol ∁ are also used) an arbitrary category; the number ...
The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...
