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."

Cave

A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos.

Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking.

Types and formation

The formation and development of caves is known as speleogenesis. Caves are formed by various geologic processes and can be variable sizes. These may involve a combination of chemical processes, erosion from water, tectonic forces, microorganisms, pressure, and atmospheric influences.

It is estimated that the maximum depth of a cave cannot be more than 3,000 metres (9,800 ft) due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks.

Cave, Lazio

Cave is a town and comune in the Latium region of Italy, 42 kilometres (26 mi) southeast of Rome. As of 2011 its population was of 10,421.

History

The town was mentioned first in 998 AD, and was later a fief of the Colonna family. In 1482 it was besieged by Pope Sixtus IV and obliged to surrender. It is especially known for the Treaty of Cave, signed on 12 September 1557 by plenipotentiaries of Pope Paul IV and Fernando Álvarez de Toledo, the Spanish viceroy of Naples.

Geography

Cave borders with Castel San Pietro Romano, Genazzano, Palestrina, Rocca di Cave, and Valmontone. It counts the hamlets (frazioni) of Collepalme and San Bartolomeo.
