In mathematics, a square number, sometimes also called a perfect square, is an integer that is the square of an integer; in other words, it is the product of some integer with itself. So, for example, 9 is a square number, since it can be written as 3 × 3.

The usual notation for the formula for the square of a number n is not the product n × n, but the equivalent exponentiation n², usually pronounced as "n squared". The name square number comes from the name of the shape. This is because a square with side length n has area n².

Square numbers are non-negative. Another way of saying that a (non-negative) number is a square number, is that its square root is again an integer. For example, √9 = 3, so 9 is a square number.

A positive integer that has no perfect square divisors except 1 is called square-free.

For a non-negative integer n, the nth square number is n², with 0² = 0 being the zeroth square. The concept of square can be extended to some other number systems. If rational numbers are included, then a square is the ratio of two square integers, and, conversely, the ratio of two square integers is a square (e.g., 4/9 = (2/3)²).

The Intelligence is a lo-fi post-punk rock band from Seattle, founded by Lars Finberg, drummer of the A Frames.

The Intelligence was formed by Lars Finberg. Finberg played since the late '90s in other bands with vocalist/guitarist Erin Sullivan, and bassist Min Yee (the Dipers, Unnatural Helpers).

A-Frames and the Intelligence started in 1999. Both acts released singles on Dragnet Records, the indie label Finberg runs with A-Frames members Erin Sullivan and Min Yee.

In 2000, Dragnet released the first A-Frames single, recorded by Chris Woodhouse. S-S Records (founded by Scott Soriano & Sakura Saunders) released the band's next single, Plastica, in early 2001. By that fall, the A-Frames had enough material ready for their first, self-titled album, which was co-released by Dragnet and S-S in spring 2002 and produced by Woodhouse & Soriano. They recorded their second album, A-Frames 2, that fall, and released it via S-S the following spring. Later in 2003, the band recorded initial sessions for its third full-length. Two more 7"s were to follow on S-S ("Complications" and "Police 1000") and Royal ("Crutches"). Two years after AF2, the A-Frames moved to Sub Pop, which released Black Forest (recorded with Woodhouse & Soriano) in early 2005.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.

Stephen John Fry (born 24 August 1957) is an English actor, screenwriter, author, playwright, journalist, poet, comedian, television presenter, film director, and a director of Norwich City Football Club.

Greydon Square (born Eddie Collins on September 28, 1981) is an American rapper. He is an Iraq War veteran and an outspoken atheist who promotes discussion on philosophical issues, as well as having studied physics full time before moving on to study computer science.

In May 2001, he enlisted in the United States Army. He went on to serve in the Iraq War in March 2004. After returning from Iraq, Collins began attending college in Phoenix, Arizona as a physics major.
