Infinity

Infinity (symbol: ∞) is an abstract concept describing something without any bound and is relevant in a number of fields, predominantly mathematics and physics. In mathematics, "infinity" is often treated as if it were a number (i.e., it counts or measures things: "an infinite number of terms") but it is not the same sort of number as natural or real numbers.

Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.

History

Ancient cultures had various ideas about the nature of infinity. The ancient Indians and Greeks did not define infinity in precise formalism as does modern mathematics, and instead approached infinity as a philosophical concept.

Early Greek

The earliest recorded idea of infinity comes from Anaximander, a pre-Socratic Greek philosopher who lived in Miletus. He used the word apeiron which means infinite or limitless. However, the earliest attestable accounts of mathematical infinity come from Zeno of Elea (c. 490 BCE? – c. 430 BCE?), a pre-Socratic Greek philosopher of southern Italy and member of the Eleatic School founded by Parmenides. Aristotle called him the inventor of the dialectic. He is best known for his paradoxes, described by Bertrand Russell as "immeasurably subtle and profound".

White

White is an achromatic color, literally a "color without hue", that is a mixture of the frequencies of all the colors of the visible spectrum. It is one of the most common colors in nature, the color of sunlight, snow, milk, chalk, limestone and other common minerals. In many cultures white represents or signifies purity, innocence, and light, and is the symbolic opposite of black, or darkness. According to surveys in Europe and the United States, white is the color most often associated with perfection, the good, honesty, cleanliness, the beginning, the new, neutrality, and exactitude.

In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity; the widows of kings dressed in white rather than black as the color of mourning. It sometimes symbolizes royalty; it was the color of the French kings (black being the color of the queens) and of the monarchist movement after the French Revolution as well as of the movement called the White Russians (not to be confounded with Belarus, literally "White Russia") who fought the Bolsheviks during the Russian Civil War (1917-1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches, capitols and other government buildings, especially in the United States of America. It was also widely used in 20th century modern architecture as a symbol of modernity, simplicity and strength.

White and Black in chess

In chess, the player who moves first is referred to as "White" and the player who moves second is referred to as "Black". Similarly, the pieces that each conducts are called, respectively, "the white pieces" and "the black pieces". The pieces are often not literally white and black, but some other colors (usually a light color and a dark color, respectively). The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise referred to as "white squares" or "light squares" on the one hand, and "black squares" or "dark squares" on the other. In most cases, the squares are not actually white and black, but a light color and a contrasting dark color. For example, the squares on plastic boards are often off-white ("buff") and green, while those on wood boards are often light brown and dark brown.

In old chess writings, the sides are often called Red and Black, because those were the two colors of ink then commonly available when hand-drawing or printing chess position diagrams.

White (political adjective)

White or White- (белый, бело-), was a political term used as an adjective, noun or a prefix by Bolsheviks to designate their real and alleged enemies of all sorts, by analogy with the White Army.

Felt (album)

Felt is the debut studio album by Anchor & Braille, the side-project of Anberlin lead vocalist, Stephen Christian. The album was released through Christian's own label Wood Water Records and Federal Distribution on August 4, 2009 and was produced, engineered and mixed by Aaron Marsh from fellow Florida-based band Copeland.

Felt debuted at number 30 on the Billboard Top Heatseekers chart.

Release and promotion

Felt is the first release on Christian's own record label, Wood Water Records. Wood Water is distributed by Anberlin's record label Universal Music Group. The album's title was explained by Christian in a press release by the label, "I named the record Felt at the request of a friend because the meaning, much like the songs on the record, has two different levels; a surface and a deeper. The first meaning of the word ‘Felt’ is the past tense of the word ‘feels’ because these songs are all past memories, which I have learned, mourned, and grown from. The second meaning of ‘felt’ is the fabric which connotates a very sensual imagery, hopefully much like the music and melodies themselves."
