In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be convex or star. In the limit, a sequence of regular polygons with an increasing number of sides becomes a circle, if the perimeter is fixed, or a regular apeirogon, if the edge length is fixed.
These properties apply to all regular polygons, whether convex or star.
A regular n-sided polygon has rotational symmetry of order n.
All vertices of a regular polygon lie on a common circle (the circumscribed circle), i.e., they are concyclic points. That is, a regular polygon is a cyclic polygon.
Together with the property of equal-length sides, this implies that every regular polygon also has an inscribed circle or incircle that is tangent to every side at the midpoint. Thus a regular polygon is a tangential polygon.
A regular n-sided polygon can be constructed with compass and straightedge if and only if the odd prime factors of n are distinct Fermat primes. See constructible polygon.
Ass is the fourth studio album by British rock band Badfinger, and their last album released on Apple Records. The opening track, "Apple of My Eye", refers to the band leaving the label to begin its new contract with Warner Bros. Records. The cover artwork, showing a donkey chasing a distant carrot, alludes to Badfinger's feelings that they had been misled by Apple over the years. The cover was painted by Grammy Award-winning artist Peter Corriston, who would later create album covers for Led Zeppelin (Physical Graffiti) and the Rolling Stones (Some Girls, Tattoo You).
Although recordings for the album began as early as 1972, shortly after the release of Straight Up, Ass wasn't released until 26 November 1973 in the US and May 1974 in the UK. The album was originally delayed because of production quality, as the band attempted to produce the album themselves after producer Todd Rundgren departed the project with just two songs recorded. After a first version of the album was rejected by the label, Apple engineer Chris Thomas was hired as a first-time producer to improve the overall recordings and make new track selections.
Octane rating or octane number is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). In broad terms, fuels with a higher octane rating are used in high performance gasoline engines that require higher compression ratios. In contrast, fuels with lower octane numbers (but higher cetane numbers) are ideal for diesel engines, because diesel engines (also referred to as compression-ignition engines) do not compress the fuel but rather compress only air and then inject the fuel into the air heated up by compression. Gasoline engines rely on ignition of air and fuel compressed together as a mixture without ignition, which is then ignited at the end of the compression stroke using spark plugs. Therefore, high compressibility of the fuel matters mainly for gasoline engines. Use of gasoline with lower octane numbers may lead to the problem of engine knocking.
Friends is an album recorded and released by Chick Corea in 1978.
The album does away with the string and horn sections of previous albums, instead focusing on a quartet with straight-ahead jazz in mind. The album cover features the Smurfs; a somewhat rare alternative cover replaces the Smurfs with porcelain animals, possibly for copyright reasons.
This album is one of three that Corea released in 1978, along with The Mad Hatter and Secret Agent. 1978 also featured the release of live albums An Evening With Herbie Hancock & Chick Corea: In Concert and RTF Live with Return to Forever.
Friends was nominated for, and received the 1979 Grammy award for Best Jazz Instrumental Performance, Group.
All pieces are composed by Chick Corea
Gwibber /ˈɡwɪbər/ is a microblogging client for the GNOME desktop environment. It brings the most popular social networking services like Facebook, Twitter, etc. into a single window and gives ability to control communication through one single application. It was created by Ryan Paul, a writer for Ars Technica.
It only runs on Linux and is written in Python using PyGTK. It ships with Ubuntu 10.04 and above. Gwibber supports multiple social networking sites in a combined social stream with URL shortening, saved searches, and a multicolumn UI.
In 2013 it was renamed to Friends and the frontend was rewritten in QML.
This is a discography of music related to the American sitcom Friends.
Friends Original TV Soundtrack was an album released by WEA in 1995 featuring songs from the TV sitcom Friends. The songs were not originals written for the series but rather were tracks either used directly in the show or "inspired" by the show. The album also featured small samples of spoken dialogue from the show's first season.
