Cube (algebra)
In arithmetic and algebra, the cube of a number n is its third power: the result of the number multiplied by itself twice:
It is also the number multiplied by its square:
This is also the volume formula for a geometric cube with sides of length n, giving rise to the name. The inverse operation of finding a number whose cube is n is called extracting the cube root of n. It determines the side of the cube of a given volume. It is also n raised to the one-third power.
Both cube and cube root are odd functions:
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3.
In integers
A cube number, or a perfect cube, or sometimes just a cube, is a number which is the cube of an integer. The positive perfect cubes up to 603 are (sequence A000578 in OEIS):
Geometrically speaking, a positive number m is a perfect cube if and only if one can arrange m solid unit cubes into a larger, solid cube. For example, 27 small cubes can be arranged into one larger one with the appearance of a Rubik's Cube, since 3 × 3 × 3 = 27.
The Power of Three (Doctor Who)
"The Power of Three" is the fourth episode of the seventh series of the British science fiction television programme Doctor Who that aired on BBC One and BBC One HD on 22 September 2012. It was written by Chris Chibnall and directed by Douglas Mackinnon.
In the episode, alien time traveller the Doctor (Matt Smith) spends time on Earth with his travelling companions Amy Pond (Karen Gillan) and her husband Rory (Arthur Darvill) while he awaits activity from millions of small cubes that appeared overnight.
"The Power of Three" focused on Amy and Rory's point of view and the impact of the Doctor's influence on their lives, as they would be leaving in the next episode. The story was inspired by The Man Who Came to Dinner and the story of the MSC Napoli. The episode also saw the return of UNIT and introduced their new scientific advisor, Kate Stewart (Jemma Redgrave), daughter of Brigadier Lethbridge-Stewart. The episode featured brief cameo appearances by Lord Sugar and professor Brian Cox. Despite being the penultimate episode in the first block of the series, "The Power of Three" was the last to be filmed, and was thus the last episode for Gillan and Darvill.
