Metropolis

A metropolis is a large city or urban area which is a significant economic, political, and cultural center for a country or region, and an important hub for regional or international connections, commerce, and communications. The term is Greek and means the "mother city" of a colony (in the ancient sense), that is, the city which sent out settlers. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation.

A big city belonging to a larger urban agglomeration, but which is not the core of that agglomeration, is not generally considered a metropolis but a part of it. The plural of the word is most commonly metropolises.

For urban centers outside metropolitan areas that generate a similar attraction at smaller scale for their region, the concept of the regiopolis, short regio, was introduced by German professors in 2006.

History

In the past, metropolis was the designation for a city or state of origin of a colony. Many large cities founded by ancient civilizations have been considered important world metropolises of their times due to their large populations and importance. Some of these ancient metropolises survived until the modern days and are among the world's oldest continuously inhabited cities.

The Midsummer Station

The Midsummer Station is the fourth studio album by American electronica project Owl City, released on August 17, 2012.

Writing and development

After Owl City's previous album, All Things Bright and Beautiful (2011) sold only 143,000 copies in the United States, Adam Young began working on demo tracks for The Midsummer Station in January 2012. Unlike his previous albums, Young worked with different songwriters and producers for the first time, including Stargate and Emily Wright. However, Young again collaborated with Matthew Thiessen for his third album in a row along with Ocean Eyes and All Things Bright and Beautiful. Young was initially scared of the thought of collaborating with others, "I've never worked with anybody before. I've done everything myself except for mastering. It's a big job for one guy, especially a perfectionist, so I knew I wanted to try to experiment with other people." The song "Dementia", which features Blink-182 singer Mark Hoppus, was mixed by Chris Lord-Alge.

Metropolis (Swords album)

Metropolis is the first studio album by the indie rock band Swords. It was released in 2005 on Arena Rock Recording Co.. The album is the third release from the group, originally named The Swords Project.

Chess theory

The game of chess is commonly divided into three phases: the opening, middlegame, and endgame. There is a large body of theory regarding how the game should be played in each of these phases, especially the opening and endgame. Those who write about chess theory, who are often but not necessarily also eminent players, are referred to as "theorists" or "theoreticians".

"Opening theory" commonly refers to consensus, broadly represented by current literature on the openings. "Endgame theory" consists of statements regarding specific positions, or positions of a similar type, though there are few universally applicable principles. "Middlegame theory" often refers to maxims or principles applicable to the middlegame. The modern trend, however, is to assign paramount importance to analysis of the specific position at hand rather than to general principles.

The development of theory in all of these areas has been assisted by the vast literature on the game. In 1913, preeminent chess historian H. J. R. Murray wrote in his 900-page magnum opus A History of Chess that, "The game possesses a literature which in contents probably exceeds that of all other games combined." He estimated that at that time the "total number of books on chess, chess magazines, and newspapers devoting space regularly to the game probably exceeds 5,000". In 1949, B. H. Wood opined that the number had increased to about 20,000.David Hooper and Kenneth Whyld wrote in 1992 that, "Since then there has been a steady increase year by year of the number of new chess publications. No one knows how many have been printed..." The world's largest chess library, the John G. White Collection at the Cleveland Public Library, contains over 32,000 chess books and serials, including over 6,000 bound volumes of chess periodicals. Chess players today also avail themselves of computer-based sources of information.

Scientific theory

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. As with most (if not all) forms of scientific knowledge, scientific theories are inductive in nature and aim for predictive power and explanatory capability.

The strength of a scientific theory is related to the diversity of phenomena it can explain, and to its elegance and simplicity. See Occam's razor. As additional scientific evidence is gathered, a scientific theory may be rejected or modified if it does not fit the new empirical findings; in such circumstances, a more accurate theory is then desired. In certain cases, the less-accurate unmodified scientific theory can still be treated as a theory if it is useful (due to its sheer simplicity) as an approximation under specific conditions (e.g., Newton's laws of motion as an approximation to special relativity at velocities which are small relative to the speed of light).
