This is a table of Clebsch–Gordan coefficients used for adding angular momentum values in quantum mechanics.The overall sign of the coefficients for each set of constant , , is arbitrary to some degree and has been fixed according to the Condon–Shortley and Wigner sign convention as discussed by Baird and Biedenharn.

Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
Q-function. A plot of the Q-function. In statistics, the Q-function is the tail distribution function of the standard normal distribution. [1][2] In other words, is the probability that a normal (Gaussian) random variable will obtain a value larger than standard deviations. Equivalently, is the probability that a standard normal random variable ...

The Bell UH-1 Iroquois (nicknamed " Huey ") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military.
First flight. 23 December 1974; 49 years ago (1974-12-23) The Rockwell B-1 Lancer[b] is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It has been nicknamed the "Bone" (from "B-One"). [2][3] It is one of the Air Force's three strategic bombers, along with the B-2 Spirit and the B-52 Stratofortress, as of 2024.
4 ft 8 + 1⁄2 in (1,435 mm) standard gauge. The Chicago, Burlington and Quincy Railroad (reporting mark CBQ) was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington Route, the Burlington, CB&Q, or as the Q, [2][3] it operated extensive trackage in the states of Colorado, Illinois, Iowa, Missouri ...
The Chicago Burlington and Quincy O-5 was a class of 36 4-8-4 "Northern" type steam locomotives built by the Baldwin Locomotive Works in 1930 and the Chicago, Burlington and Quincy Railroad (CB&Q) between 1936 and 1940 and operated by the CB&Q until the late 1950s. The locomotives saw service pulling both freight and passenger trains and four ...
The golden ratio φ and its negative reciprocal −φ −1 are the two roots of the quadratic polynomial x 2 − x − 1. The golden ratio's negative −φ and reciprocal φ −1 are the two roots of the quadratic polynomial x 2 + x − 1. The golden ratio is also an algebraic number and even an algebraic integer. It has minimal polynomial
