Chief executive officer
The chief executive officer or just chief executive, is the most senior corporate, executive, or administrative officer in charge of managing an organization – an independent legal entity such as a company or nonprofit institution. CEOs lead a range of organizations, including public and private corporations, non-profit organizations and some government organizations; the CEO of a corporation or company reports to the board of directors and is charged with maximizing the value of the entity, which may include maximizing the share price, market share, revenues or another element. In the non-profit and government sector, CEOs aim at achieving outcomes related to the organization's mission, such as reducing poverty, increasing literacy, etc. In the early 21st century, top executives had technical degrees in science, engineering or law; the responsibility of an organization's CEO are set by the organization's board of directors or other authority, depending on the organization's legal structure.
They can be far-reaching or quite limited and are enshrined in a formal delegation of authority. Responsibilities include being a decision maker on strategy and other key policy issues, leader and executor; the communicator role can involve speaking to the press and the rest of the outside world, as well as to the organization's management and employees. As a leader of the company, the CEO or MD advises the board of directors, motivates employees, drives change within the organization; as a manager, the CEO/MD presides over the organization's day-to-day operations. The term refers to the person who makes all the key decisions regarding the company, which includes all sectors and fields of the business, including operations, business development, human resources, etc; the CEO of a company is not the owner of the company. In some countries, there is a dual board system with two separate boards, one executive board for the day-to-day business and one supervisory board for control purposes. In these countries, the CEO presides over the executive board and the chairman presides over the supervisory board, these two roles will always be held by different people.
This ensures a distinction between management by the executive board and governance by the supervisory board. This allows for clear lines of authority; the aim is to prevent a conflict of interest and too much power being concentrated in the hands of one person. In the United States, the board of directors is equivalent to the supervisory board, while the executive board may be known as the executive committee. In the United States, in business, the executive officers are the top officers of a corporation, the chief executive officer being the best-known type; the definition varies. In the case of a sole proprietorship, an executive officer is the sole proprietor. In the case of a partnership, an executive officer is a managing partner, senior partner, or administrative partner. In the case of a limited liability company, executive officer is any manager, or officer. A CEO has several subordinate executives, each of whom has specific functional responsibilities referred to as senior executives, executive officers or corporate officers.
Subordinate executives are given different titles in different organizations, but one common category of subordinate executive, if the CEO is the president, is the vice-president. An organization may have more than one vice-president, each tasked with a different area of responsibility; some organizations have subordinate executive officers who have the word chief in their job title, such as chief operating officer, chief financial officer and chief technology officer. The public relations-focused position of chief reputation officer is sometimes included as one such subordinate executive officer, but, as suggested by Anthony Johndrow, CEO of Reputation Economy Advisors, it can be seen as "simply another way to add emphasis to the role of a modern-day CEO – where they are both the external face of, the driving force behind, an organisation culture". In the US, the term chief executive officer is used in business, whereas the term executive director is used in the not-for-profit sector; these terms are mutually exclusive and refer to distinct legal duties and responsibilities.
Implicit in the use of these titles, is that the public not be misled and the general standard regarding their use be applied. In the UK, chief executive and chief executive officer are used in both business and the charitable sector; as of 2013, the use of the term director for senior charity staff is deprecated to avoid confusion with the legal duties and responsibilities associated with being a charity director or trustee, which are non-executive roles. In the United Kingdom, the term director is used instead of chief officer". Business publicists since the days of Edward Bernays and his client John D. Rockefeller and more the corporate publicists for Henry Ford, promoted the concept of the "celebrity CEO". Business journalists have adopted this approach, which assumes that the corporate achievements in the arena of manufacturing, wer
United States dollar
The United States dollar is the official currency of the United States and its territories per the United States Constitution since 1792. In practice, the dollar is divided into 100 smaller cent units, but is divided into 1000 mills for accounting; the circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars. Since the suspension in 1971 of convertibility of paper U. S. currency into any precious metal, the U. S. dollar is, de facto, fiat money. As it is the most used in international transactions, the U. S. dollar is the world's primary reserve currency. Several countries use it as their official currency, in many others it is the de facto currency. Besides the United States, it is used as the sole currency in two British Overseas Territories in the Caribbean: the British Virgin Islands and Turks and Caicos Islands. A few countries use the Federal Reserve Notes for paper money, while still minting their own coins, or accept U. S. dollar coins. As of June 27, 2018, there are $1.67 trillion in circulation, of which $1.62 trillion is in Federal Reserve notes.
Article I, Section 8 of the U. S. Constitution provides that the Congress has the power "To coin money". Laws implementing this power are codified at 31 U. S. C. § 5112. Section 5112 prescribes the forms; these coins are both designated in Section 5112 as "legal tender" in payment of debts. The Sacagawea dollar is one example of the copper alloy dollar; the pure silver dollar is known as the American Silver Eagle. Section 5112 provides for the minting and issuance of other coins, which have values ranging from one cent to 100 dollars; these other coins are more described in Coins of the United States dollar. The Constitution provides that "a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time"; that provision of the Constitution is made specific by Section 331 of Title 31 of the United States Code. The sums of money reported in the "Statements" are being expressed in U. S. dollars. The U. S. dollar may therefore be described as the unit of account of the United States.
The word "dollar" is one of the words in the first paragraph of Section 9 of Article I of the Constitution. There, "dollars" is a reference to the Spanish milled dollar, a coin that had a monetary value of 8 Spanish units of currency, or reales. In 1792 the U. S. Congress passed a Coinage Act. Section 9 of that act authorized the production of various coins, including "DOLLARS OR UNITS—each to be of the value of a Spanish milled dollar as the same is now current, to contain three hundred and seventy-one grains and four sixteenth parts of a grain of pure, or four hundred and sixteen grains of standard silver". Section 20 of the act provided, "That the money of account of the United States shall be expressed in dollars, or units... and that all accounts in the public offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation". In other words, this act designated the United States dollar as the unit of currency of the United States. Unlike the Spanish milled dollar, the U.
S. dollar is based upon a decimal system of values. In addition to the dollar the coinage act established monetary units of mill or one-thousandth of a dollar, cent or one-hundredth of a dollar, dime or one-tenth of a dollar, eagle or ten dollars, with prescribed weights and composition of gold, silver, or copper for each, it was proposed in the mid-1800s that one hundred dollars be known as a union, but no union coins were struck and only patterns for the $50 half union exist. However, only cents are in everyday use as divisions of the dollar. XX9 per gallon, e.g. $3.599, more written as $3.599⁄10. When issued in circulating form, denominations equal to or less than a dollar are emitted as U. S. coins while denominations equal to or greater than a dollar are emitted as Federal Reserve notes. Both one-dollar coins and notes are produced today, although the note form is more common. In the past, "paper money" was issued in denominations less than a dollar and gold coins were issued for circulation up to the value of $20.
The term eagle was used in the Coinage Act of 1792 for the denomination of ten dollars, subsequently was used in naming gold coins. Paper currency less than one dollar in denomination, known as "fractional currency", was sometimes pejoratively referred to as "shinplasters". In 1854, James Guthrie Secretary of the Treasury, proposed creating $100, $50 and $25 gold coins, which were referred to as a "Union", "Half Union", "Quarter Union", thus implying a denomination of 1 Union = $100. Today, USD notes are made from cotton fiber paper, unlike most common paper, made of wood fiber. U. S. coins are produced by the United States Mint. U. S. dollar banknotes are printed by the Bureau of Engraving and Printing and, since 1914, have been issued by t
Woodland Park, New Jersey
Woodland Park is a borough in Passaic County, New Jersey, United States. As of the 2010 United States Census, the borough's population was 11,819, reflecting an increase of 832 from the 10,987 counted in the 2000 Census, which had in turn increased by 5 from the 10,982 counted in the 1990 Census. What is now Woodland Park was formed as a borough under the name "West Paterson", by an act of the New Jersey Legislature on March 25, 1914, from portions of Little Falls Township, based on the results of a referendum held on May 1, 1914. On November 4, 2008, the citizens of West Paterson voted to change the official name of the borough from West Paterson to Woodland Park; the new name retains the initials "W. P." and is a reference to the community's wooded areas. At a November 10, 2008, community meeting attended by 200 residents, a number of residents demanded that a recount be held if the official results showed that the measure had passed. In case the recount demand was unsuccessful, the group discussed filing a petition to change the name back to West Paterson, including discussion of how to raise the $33,000 needed to cover the cost of a special election in spring 2009 for voters to reconsider the name.
By November 25, 2008, the provisional vote counts had been tallied, the name change won by 25 votes. The Mayor and Council approved a resolution in December 2008 changing the borough's name to the Borough of Woodland Park, effective January 1, 2009. A referendum held on November 3, 2009, affirmed the name change. According to the United States Census Bureau, the borough had a total area of 3.115 square miles, including 2.964 square miles of land and 0.151 square miles of water. Slippery Rock Brook is a tributary of the Passaic River that flows north as it drains part of the western flank of First Watchung Mountain. Traveling south from its confluence with the Passaic River, it passes through the city of Paterson and the borough of Woodland Park; the borough borders the Passaic County municipalities of Clifton, Little Falls and Totowa. Borough residents voted in November 2008 to change the community's name to Woodland Park; this close decision — the majority was only 33 votes according to early results — marked the fourth attempt to change the borough's historic name of West Paterson: voters rejected the names "Whispering Pines", "West Park," and "Garret Mountain" in 1989, 1995, 2001 respectively.
Such a change is not unique in recent New Jersey history: Dover Township in Ocean County became Toms River Township in November 2006, Washington Township in Mercer County became Robbinsville Township in November 2007. The borough of East Paterson, located in adjacent Bergen County, changed its name to Elmwood Park in 1972. Both East and West Paterson changed their names in hopes of dissociating themselves from the larger city of Paterson, poorer and faces higher levels of crime, while preserving their E. P. and W. P. initials. In West Paterson, proponents of name change argued that their proposal would improve the borough's reputation and thus property values within the borough, as outsiders would be less to confuse it with Paterson. Opponents of the renaming saw no need to change, with businesses and the fire department citing the cost of changing references to the borough's name and the consequences of forgetting the community's history as West Paterson; the name change has been marred with accusations of racism and discrimination due to the city of Paterson's lower quality of life and diverse minority demographics.
Some Paterson residents and advocates have jokingly suggested renaming Paterson to East Woodland Park and West Elmwood Park. Residents who voted "No" to the name change petitioned the municipal government in an attempt to change the name back to West Paterson. A referendum was held on November 3, 2009, the proposal was defeated by 2,248 votes to 2,216. There is an unincorporated area called Woodland Park in the city of Summit, in Union County, adjacent to New Providence. Cytec Industries is materials technology company. Cytec was created in a 1993 spin off of American Cyanamid's industrial chemicals businesses. In July 2015, Solvay S. A. announced its intent to acquire Cytec for a purchase price of US $5.5 billion. North Jersey Media Group is the parent company of The Herald News newspapers; the company relocated the operations of the Herald News to Woodland Park in 1999, shifted its staff at The Record from Hackensack to Woodland Park from 2008 through 2010. Garret Mountain Reservation is a county park covering 568 acres.
The site of Lambert Castle, the park offers views of the New York City skyline, as it rises 500 feet above sea level. Rifle Camp Park is a county park covering 225 acres located within Woodland Park, but its eastern edge extends into Clifton as well; the park includes hiking trails, an observatory, nature center, fitness trail, amphitheater, a bird watching blind, an overnight camping facility for local scout organizations. As of the 2010 United States Census, there were 11,819 people, 4,632 households, 3,214.608 families residing in the borough. The population density was 3,987.9 per square mile. There were 4,835 housing units at an average density of 1,631.4 per square mile. The racial makeup of the borough was 82.33% White, 4.23% Black or African American, 0.16% Native American, 4.20% Asian, 0.10% Pacific Islander, 6.15% from other races, 2.83% from two or more races. Hispanic or Latino of any race were 20.66% of the population. There were 4,632 households out of which 26.9% had children under the age of 18 living with them, 52.7% were married couples living toge
A chemical substance is a form of matter having constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds. Chemical substances can be chemical compounds, or alloys. Chemical elements may not be included in the definition, depending on expert viewpoint. Chemical substances are called'pure' to set them apart from mixtures. A common example of a chemical substance is pure water. Other chemical substances encountered in pure form are diamond, table salt and refined sugar. However, in practice, no substance is pure, chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, gases, or plasma, may change between these phases of matter with changes in temperature or pressure. Chemical substances may be converted to others by means of chemical reactions. Forms of energy, such as light and heat, are not matter, are thus not "substances" in this regard.
A chemical substance may well be defined as "any material with a definite chemical composition" in an introductory general chemistry textbook. According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. But, there are exceptions to this definition; the chemical substance index published by CAS includes several alloys of uncertain composition. Non-stoichiometric compounds are a special case that violates the law of constant composition, for them, it is sometimes difficult to draw the line between a mixture and a compound, as in the case of palladium hydride. Broader definitions of chemicals or chemical substances can be found, for example: "the term'chemical substance' means any organic or inorganic substance of a particular molecular identity, including – any combination of such substances occurring in whole or in part as a result of a chemical reaction or occurring in nature". In geology, substances of uniform composition are called minerals, while physical mixtures of several minerals are defined as rocks.
Many minerals, mutually dissolve into solid solutions, such that a single rock is a uniform substance despite being a mixture in stoichiometric terms. Feldspars are a common example: anorthoclase is an alkali aluminum silicate, where the alkali metal is interchangeably either sodium or potassium. In law, "chemical substances" may include both pure substances and mixtures with a defined composition or manufacturing process. For example, the EU regulation REACH defines "monoconstituent substances", "multiconstituent substances" and "substances of unknown or variable composition"; the latter two consist of multiple chemical substances. For example, charcoal is an complex polymeric mixture that can be defined by its manufacturing process. Therefore, although the exact chemical identity is unknown, identification can be made to a sufficient accuracy; the CAS index includes mixtures. Polymers always appear as mixtures of molecules of multiple molar masses, each of which could be considered a separate chemical substance.
However, the polymer may be defined by a known precursor or reaction and the molar mass distribution. For example, polyethylene is a mixture of long chains of -CH2- repeating units, is sold in several molar mass distributions, LDPE, MDPE, HDPE and UHMWPE; the concept of a "chemical substance" became established in the late eighteenth century after work by the chemist Joseph Proust on the composition of some pure chemical compounds such as basic copper carbonate. He deduced; this is now known as the law of constant composition. With the advancement of methods for chemical synthesis in the realm of organic chemistry. However, there are some controversies regarding this definition because the large number of chemical substances reported in chemistry literature need to be indexed. Isomerism caused much consternation to early researchers, since isomers have the same composition, but differ in configuration of the atoms. For example, there was much speculation for the chemical identity of benzene, until the correct structure was described by Friedrich August Kekulé.
The idea of stereoisomerism – that atoms have rigid three-dimensional structure and can thus form isomers that differ only in their three-dimensional arrangement – was another crucial step in understanding the concept of distinct chemical substances. For example, tartaric acid has three distinct isomers, a pair of diastereomers with one diastereomer forming two enantiomers. An element is a chemical substance made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmuted into another element through a nuclear reaction; this is so, beca
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. A stock symbol may consist of numbers or a combination of both. "Ticker symbol" refers to the symbols. Stock symbols are unique identifiers assigned to each security traded on a particular market. A stock symbol can consist of letters, numbers, or a combination of both, is a way to uniquely identify that stock; the symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, to make it easy to recognize by traders and investors. The allocation of symbols and formatting convention is specific to each stock exchange. In the US, for example, stock tickers are between 1 and 4 letters and represent the company name where possible. For example, US-based computer company stock Apple Inc. traded on the NASDAQ exchange has the symbol AAPL, while the motor company Ford's stock, traded on the New York Stock Exchange has the single-letter ticker F.
In Europe, most exchanges use three-letter codes, for example Dutch consumer goods company Unilever traded on the Amsterdam Euronext exchange has the symbol UNA. While in Asia, numbers are used as stock tickers to avoid issues for international investors when using non-Latin scripts. For example, the bank HSBC's stock traded on the Hong Kong Stock Exchange has the ticker symbol 0005. Symbols sometimes change to reflect mergers. Prior to the 1999 merger with Mobil Oil, Exxon used a phonetic spelling of the company "XON" as its ticker symbol; the symbol of the firm after the merger was "XOM". Symbols are sometimes reused. In the US the single-letter symbols are sought after as vanity symbols. For example, since Mar 2008 Visa Inc. has used the symbol V, used by Vivendi which had delisted and given up the symbol. To qualify a stock, both the ticker and the exchange or country of listing needs to be known. On many systems both must be specified to uniquely identify the security; this is done by appending the location or exchange code to the ticker.
Although stock tickers identify a security, they are exchange dependent limited to stocks and can change. These limitations have led to the development of other codes in financial markets to identify securities for settlement purposes; the most prevalent of these is the International Securities Identifying Number. An ISIN uniquely identifies a security and its structure is defined in ISO 6166. Securities for which ISINs are issued include bonds, commercial paper and warrants; the ISIN code is a 12-character alpha-numerical code that does not contain information characterizing financial instruments, but serves for uniform identification of a security at trading and settlement. The ISIN identifies not the exchange on which it trades. For instance, Daimler AG stock trades on twenty-two different stock exchanges worldwide, is priced in five different currencies. ISIN cannot specify a particular trade in this case, another identifier the three- or four-letter exchange code will have to be specified in addition to the ISIN.
While a stock ticker identifies a security that can be traded, stock market indices are sometimes assigned a symbol though they can not be traded. Symbols for indices are distinguished by adding a symbol in front of the name, such as a caret or a dot. For example, Reuters lists the Nasdaq Composite index under the symbol. IXIC. In Canada the Toronto Stock Exchange TSX and the TSXV use the following special codes after the ticker symbol: In the United Kingdom, prior to 1996, stock codes were known as EPICs, named after the London Stock Exchange's Exchange Price Information Computer. Following the introduction of the Sequence trading platform in 1996, EPICs were renamed Tradable Instrument Display Mnemonics, but they are still referred to as EPICs. Stocks can be identified using their SEDOL number or their ISIN. In the United States, modern letter-only ticker symbols were developed by Standard & Poor's to bring a national standard to investing. A single company could have many different ticker symbols as they varied between the dozens of individual stock markets.
The term ticker refers to the noise made by the ticker tape machines once used by stock exchanges. The S&P system was standardized by the securities industry and modified as years passed. Stock symbols for preferred stock have not been standardized; some companies use a well-known product as their ticker symbol. Belgian brewer InBev, the brewer of Budweiser beer, uses "BUD" as its three-letter ticker for American Depository Receipts, symbolizing its premier product in the United States, its rival, Molson Coors Brewing Company, uses a beer-related symbol, "TAP". Southwest Airlines pays tribute to its headquarters at Love Field in Dallas through its "LUV" symbol. Cedar Fair Entertainment Company, which operates large amusement parks in the United States, uses "FUN" as its symbol. Harley-Davidson uses "HOG" for its Harley Owners Group. Yamana Gold uses "AUY", because on the periodic table of elements. Sotheby's uses the symbol "BID". While most symbols come from the company's name, sometimes it happens the other way around.

A composite material is a material made from two or more constituent materials with different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure, differentiating composites from mixtures and solid solutions; the new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More researchers have begun to include sensing, actuation and communication into composites, which are known as Robotic Materials. Typical engineered composite materials include: Reinforced concrete and masonry Composite wood such as plywood Reinforced plastics, such as fibre-reinforced polymer or fiberglass Ceramic matrix composites Metal matrix composites and other Advanced composite materialsComposite materials are used for buildings and structures such as boat hulls, swimming pool panels, racing car bodies, shower stalls, storage tanks, imitation granite and cultured marble sinks and countertops.
The most advanced examples perform on spacecraft and aircraft in demanding environments. The earliest man-made composite materials were straw and mud combined to form bricks for building construction. Ancient brick-making was documented by Egyptian tomb paintings. Wattle and daub is one of the oldest man-made composite materials, at over 6000 years old. Concrete is a composite material, is used more than any other man-made material in the world; as of 2006, about 7.5 billion cubic metres of concrete are made each year—more than one cubic metre for every person on Earth. Woody plants, both true wood from trees and such plants as palms and bamboo, yield natural composites that were used prehistorically by mankind and are still used in construction and scaffolding. Plywood 3400 BC by the Ancient Mesopotamians. Cartonnage layers of linen or papyrus soaked in plaster dates to the First Intermediate Period of Egypt c. 2181–2055 BC and was used for death masks. Cob Mud Bricks, or Mud Walls, have been used for thousands of years.
Concrete was described by Vitruvius, writing around 25 BC in his Ten Books on Architecture, distinguished types of aggregate appropriate for the preparation of lime mortars. For structural mortars, he recommended pozzolana, which were volcanic sands from the sandlike beds of Pozzuoli brownish-yellow-gray in colour near Naples and reddish-brown at Rome. Vitruvius specifies a ratio of 1 part lime to 3 parts pozzolana for cements used in buildings and a 1:2 ratio of lime to pulvis Puteolanus for underwater work the same ratio mixed today for concrete used at sea. Natural cement-stones, after burning, produced cements used in concretes from post-Roman times into the 20th century, with some properties superior to manufactured Portland cement. Papier-mâché, a composite of paper and glue, has been used for hundreds of years; the first artificial fibre reinforced plastic was bakelite which dates to 1907, although natural polymers such as shellac predate it. One of the most common and familiar composite is fibreglass, in which small glass fibre are embedded within a polymeric material.
The glass fibre is strong and stiff, whereas the polymer is ductile. Thus the resulting fibreglass is stiff, strong and ductile. Concrete is the most common artificial composite material of all and consists of loose stones held with a matrix of cement. Concrete is an inexpensive material, will not compress or shatter under quite a large compressive force. However, concrete cannot survive tensile loading. Therefore, to give concrete the ability to resist being stretched, steel bars, which can resist high stretching forces, are added to concrete to form reinforced concrete. Fibre-reinforced polymers s include glass-reinforced plastic. If classified by matrix there are thermoplastic composites, short fibre thermoplastics, long fibre thermoplastics or long fibre-reinforced thermoplastics. There are numerous thermoset composites, including paper composite panels. Many advanced thermoset polymer matrix systems incorporate aramid fibre and carbon fibre in an epoxy resin matrix. Shape memory polymer composites are high-performance composites, formulated using fibre or fabric reinforcement and shape memory polymer resin as the matrix.
Since a shape memory polymer resin is used as the matrix, these composites have the ability to be manipulated into various configurations when they are heated above their activation temperatures and will exhibit high strength and stiffness at lower temperatures. They can be reheated and reshaped without losing their material properties; these composites are ideal for applications such as lightweight, deployable structures. High strain composites are another type of high-performance composites that are designed to perform in a high deformation setting and are used in deployable systems where structural flexing is advantageous. Although high strain composites exhibit many similarities to shape memory polymers, their performance is dependent on the fibre layout as opposed to the resin content of the matrix. Comp
Aerospace is the human effort in science and business to fly in the atmosphere of Earth and surrounding space. Aerospace organizations research, manufacture, operate, or maintain aircraft or spacecraft. Aerospace activity is diverse, with a multitude of commercial and military applications. Aerospace is not the same as airspace, the physical air space directly above a location on the ground; the beginning of space and the ending of the air is considered as 100km above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. In most industrial countries, the aerospace industry is a cooperation of public and private industries. For example, several countries have a civilian space program funded by the government through tax collection, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Research Organisation in India, Japanese Aeronautics Exploration Agency in Japan, RKA in Russia, China National Space Administration in China, SUPARCO in Pakistan, Iranian Space Agency in Iran, Korea Aerospace Research Institute in South Korea.
Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include Boeing, Airbus, SpaceX, Lockheed Martin, United Technologies, MacDonald Dettwiler and Northrop Grumman; these companies are involved in other areas of aerospace such as the construction of aircraft. Modern aerospace began with Engineer George Cayley in 1799. Cayley proposed an aircraft with a "fixed wing and a horizontal and vertical tail," defining characteristics of the modern airplane; the 19th century saw the creation of the Aeronautical Society of Great Britain, the American Rocketry Society, the Institute of Aeronautical Sciences, all of which made aeronautics a more serious scientific discipline. Airmen like Otto Lilienthal, who introduced cambered airfoils in 1891, used gliders to analyze aerodynamic forces; the Wright brothers read several of his publications. They found inspiration in Octave Chanute, an airman and the author of Progress in Flying Machines.
It was the preliminary work of Cayley, Lilienthal and other early aerospace engineers that brought about the first powered sustained flight at Kitty Hawk, North Carolina on December 17, 1903, by the Wright brothers. War and science fiction inspired great minds like Konstantin Tsiolkovsky and Wernher von Braun to achieve flight beyond the atmosphere; the launch of Sputnik 1 in October 1957 started the Space Age, on July 20, 1969 Apollo 11 achieved the first manned moon landing. In April 1981, the Space Shuttle Columbia launched, the start of regular manned access to orbital space. A sustained human presence in orbital space started with "Mir" in 1986 and is continued by the "International Space Station". Space commercialization and space tourism are more recent features of aerospace. Aerospace manufacturing is a high-technology industry that produces "aircraft, guided missiles, space vehicles, aircraft engines, propulsion units, related parts". Most of the industry is geared toward governmental work.
For each original equipment manufacturer, the US government has assigned a Commercial and Government Entity code. These codes help to identify each manufacturer, repair facilities, other critical aftermarket vendors in the aerospace industry. In the United States, the Department of Defense and the National Aeronautics and Space Administration are the two largest consumers of aerospace technology and products. Others include the large airline industry; the aerospace industry employed 472,000 wage and salary workers in 2006. Most of those jobs were in Washington state and in California, with Missouri, New York and Texas being important; the leading aerospace manufacturers in the U. S. are United Technologies Corporation, SpaceX, Northrop Grumman and Lockheed Martin. These manufacturers are facing an increasing labor shortage as skilled U. S. workers retire. Apprenticeship programs such as the Aerospace Joint Apprenticeship Council work in collaboration with Washington state aerospace employers and community colleges to train new manufacturing employees to keep the industry supplied.
Important locations of the civilian aerospace industry worldwide include Washington state, California. In the European Union, aerospace companies such as EADS, BAE Systems, Dassault, Saab AB and Leonardo S.p. A. account for a large share of the global aerospace industry and research effort, with the European Space Agency as one of the largest consumers of aerospace technology and products. In India, Bangalore is a major center of the aerospace industry, where Hindustan Aeronautics Limited, the National Aerospace Laboratories and the Indian Space Research Organisation are headquartered; the Indian Space Research Organisation launched India's first Moon orbiter, Chandrayaan-1, in October 2008. In Russia, large aerospace companies like Oboronprom and the United Aircraft Building Corporation are among the major global players
