Engine

An engine or motor is a machine designed to convert one form of energy into mechanical energy.Heat engines, including internal combustion engines and external combustion engines (such as steam engines), burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others—such as clockwork motors in wind-up toys—use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.

Terminology

The word "engine" derives from Old French engin, from the Latin ingenium–the root of the word ingenious. Pre-industrial weapons of war, such as catapults, trebuchets and battering rams, were called "siege engines", and knowledge of how to construct them was often treated as a military secret. The word "gin", as in "cotton gin", is short for "engine". Most mechanical devices invented during the industrial revolution were described as engines—the steam engine being a notable example.

Ray Alder

Ray Alder (born as Ray Balderrama on August 20, 1967) has been the lead vocalist of the progressive metal band Fates Warning since their 1988 release No Exit.

He has released two albums Engine in 1999 and Superholic in 2002 with Engine.

He also sang on Redemption's albums The Origins of Ruin, The Fullness of Time, Snowfall on Judgment Day and This Mortal Coil, having produced their debut self-titled release in 2002.

He has recently worked with underground emcee/producer Necro for his album entitled Death Rap.

Ray Alder was featured at a show with the band Dream Theater at Los Angeles, California on May 18, 1998.

On March 16, 2010, Fates Warning released a deluxe edition of their 1991 album, Parallels. This edition has been fully re-mastered and contains over three hours of music and live footage. Parallels was one of Fates Warning's most successful releases due to the commercial success of the singles Eye To Eye, Point Of View and We Only Say Goodbye. According to Metal Blade records (2010) Parallels has proven to be one of the most influential albums in the prog and metal genres, despite its hotly debated status among fans as a "commercial" sounding album. Commenting on the album, Ray Alder is quoted on the "Metal Blade Records Website".  as follows, "I think it's one of the best albums we ever put out and I'm happy that fans have the chance to take a second look at this important record. The lineup, the songs and the cover art all came together to make a great package when originally recorded and the bonus DVD really adds a fresh perspective to the album."

Comma (music)

In music theory, a comma is a minute interval, the difference resulting from tuning one note two different ways. The word comma used without qualification refers to the syntonic comma, which can be defined, for instance, as the difference between an F♯ tuned using the D-based Pythagorean tuning system, and another F♯ tuned using the D-based quarter-comma meantone tuning system.

Within the same tuning system, two enharmonically equivalent notes (such as G♯ and A♭) may have a slightly different frequency, and the interval between them is a comma. For example, in extended scales produced with five-limit tuning an A♭ tuned as a major third below C5 and a G♯ tuned as two major thirds above C4 will not be exactly the same note, as they would be in equal temperament. The interval between those notes, the diesis, is an easily audible comma (its size is more than 40% of a semitone).

Commas are often defined as the difference in size between two semitones. Each meantone temperament tuning system produces a 12-tone scale characterized by two different kinds of semitones (diatonic and chromatic), and hence by a comma of unique size. The same is true for Pythagorean tuning.

Polygonia c-album

The Comma (Polygonia c-album) is a species of butterfly belonging to the family Nymphalidae. Its irregular wing edges are characteristic of the Polygonia genus, which is why they are commonly called anglewings. It is found in northern Africa and across Europe from Portugal through Asia as far as Japan. Its dorsal wings are colourful but its underside has a pattern that camouflages it when its wings are held together.

Description

Polygonia c-album has a wingspan of about 45 millimetres (1.8 in). The underside of the wings of this butterfly are a dull brown colour, with a small white 'C' shaped marking resembling a comma (hence the common name). The wings have a distinctive ragged edge, apparently a cryptic form as the butterfly resembles a fallen leaf.

These butterflies hibernate, so they could be seen all around the year, but the active flying period extends from April to November, depending on location. Adults feed on nectar, mainly of Thistles (Cirsium and Carduus spp.), but also on Bramble (Rubus fruticosus), Ivy (Hedera helix), Knapweeds (Centaurea spp.), and Privet (Ligustrum vulgare).
