Oil

An oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and slippery.

The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food, fuel, lubrication, and the manufacture of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies as purifying agents.

Etymology

First attested in English 1176, the word oil comes from Old French oile, from Latin oleum, which in turn comes from the Greek ἔλαιον (elaion), "olive oil, oil" and that from ἐλαία (elaia), "olive tree", "olive fruit". The earliest attested forms of the word are the Mycenaean Greek 𐀁𐀨𐀺, e-ra-wo and 𐀁𐁉𐀺, e-rai-wo, written in the Linear B syllabic script.

Technical analysis

In finance, technical analysis is a security analysis methodology for forecasting the direction of prices through the study of past market data, primarily price and volume.Behavioral economics and quantitative analysis use many of the same tools of technical analysis, which, being an aspect of active management, stands in contradiction to much of modern portfolio theory. The efficacy of both technical and fundamental analysis is disputed by the efficient-market hypothesis which states that stock market prices are essentially unpredictable.

History

The principles of technical analysis are derived from hundreds of years of financial market data. Some aspects of technical analysis began to appear in Joseph de la Vega's accounts of the Dutch markets in the 17th century. In Asia, technical analysis is said to be a method developed by Homma Munehisa during early 18th century which evolved into the use of candlestick techniques, and is today a technical analysis charting tool. In the 1920s and 1930s Richard W. Schabacker published several books which continued the work of Charles Dow and William Peter Hamilton in their books Stock Market Theory and Practice and Technical Market Analysis. In 1948 Robert D. Edwards and John Magee published Technical Analysis of Stock Trends which is widely considered to be one of the seminal works of the discipline. It is exclusively concerned with trend analysis and chart patterns and remains in use to the present. Early technical analysis was almost exclusively the analysis of charts, because the processing power of computers was not available for the modern degree of statistical analysis. Charles Dow reportedly originated a form of point and figure chart analysis.

Petroleum

Petroleum (L. petroleum, from early 15c. "petroleum, rock oil" (mid-14c. in Anglo-French), from Medieval Latin petroleum, from Latin: petra: "rock" + oleum: "oil".) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface, which is commonly refined into various types of fuels.

It consists of hydrocarbons of various molecular weights and other organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to intense heat and pressure.

Petroleum is recovered mostly through oil drilling (natural petroleum springs are rare). This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of the porosity and permeability of geologic reservoir structures). It is refined and separated, most easily by distillation, into a large number of consumer products, from gasoline (petrol) and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. Petroleum is used in manufacturing a wide variety of materials, and it is estimated that the world consumes about 90 million barrels each day.

Main Street

Main Street is a generic phrase used to denote a primary retail street of a village, town or small city in many parts of the world. It is usually a focal point for shops and retailers in the central business district, and is most often used in reference to retailing and socializing.

The term is commonly used in Ireland, Scotland, the United States, Canada, and less often in Australia and New Zealand. In most of the United Kingdom the common description is High Street. However, the term "Main Street" is sometimes used in the UK, for instance, in the village of Sutton Cheney. In Jamaica the term is Front Street. In some parts of the south west of England the equivalent used is Fore Street.

In some larger cities, there may be several Main Streets, each relating to a specific neighborhood or formerly separate city, rather than the city as a whole. In many larger U.S. cities "Main Street" is a U.S. Highway; "Main Street of America" branding was used to promote U.S. Route 66 in its heyday.

Wall Street

Wall Street is a 0.7-mile-long (1.1 km) street running eight blocks, roughly northwest to southeast, from Broadway to South Street on the East River in the Financial District of Lower Manhattan, New York City. Over time, the term has become a metonym for the financial markets of the United States as a whole, the American financial sector (even if financial firms are not physically located there), or signifying New York-based financial interests.

Anchored by Wall Street, New York City has been called both the most economically powerful city and the leading financial center of the world, and the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. Several other major exchanges have or had headquarters in the Wall Street area, including the New York Mercantile Exchange, the New York Board of Trade, and the former American Stock Exchange.

History

Early years

There are varying accounts about how the Dutch-named "de Waal Straat" got its name. A generally accepted version is that the name of the street was derived from an earthen wall on the northern boundary of the New Amsterdam settlement, perhaps to protect against English colonial encroachment or incursions by Native Americans. A conflicting explanation is that Wall Street was named after Walloons— the Dutch name for a Walloon is Waal. Among the first settlers that embarked on the ship "Nieu Nederlandt" in 1624 were 30 Walloon families. The Dutch word "wal" can be translated as "rampart". However, even some English maps show the name as Waal Straat, and not as Wal Straat.
