The most common question asked when looking for a new projector for the home, office, or classroom is: should I get an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and different models available, it can be difficult for the buyer to make a decision between these technologies. The simple fact of the matter is that LCD projectors offer far better image quality and colour accuracy. The following article will tell you why DLP projectors struggle with reproducing a comparable level of image quality.

Imagine a set of blinds in your house covering your bedroom window. By twisting a rod you can make the shutters open or closed, depending on if you want to let light in or not. That is exactly how an LCD projector behaves. Each pixel operates like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the time the projector is switched on to when the picture reaches your screen is extremely important in regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by cutting it into red, blue and green components, by three mirrors which direct the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then combined in a glass prism to form the projector image. A significant point to know about LCD projectors is that all three colours are delivered onto your projector screen at the same time. The way a DLP projector operates is vastly different and even how an image comes out is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming an image forms a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into the single whole image. With LCD projectors, all colours are available all the time to deliver the best brightness and fantastic colour accuracy. In DLP, only one colour is available at any given time, causing lower colour brightness and accuracy. Some designers have put a white segment for the colour wheel to improve overall brightness, but this further lessens colour accuracy.

I find in forums all the time that DLP provides a higher contrast ratio and thus must be superior quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of producing. DLP projectors do provide high contrast specifications compared to the majority of LCD projectors. At first glance, this appears to be a benefit, however, in truth, the true black level is determined by the ambient light in the room where the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you want to see requires moving images, DLP projection technology also has image errors, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because the colours are sent at the same time. DLP developers have formed 3DLP solutions using 3 chips to answer the colour break up error, but the expense of these projectors make them almost impossible for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and remember when they taught you how the various colours of light refract different amounts when directed through the same lens. The problem with DLP projectors is that they have the one same panel with the same lens to project Red, Blue and Green. All 3 colours are different and refract light at different levels. Usually with a DLP projector, some extra yellow colour will come up above and a superfluous blue will show below an image containing something as simple as a straight black line. While being built LCD projectors can be adapted to remove these effects on the projected image, as each colour is processed on a separate LCD panels.

The isolated actual advantage (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to portability and must be traded off against the image advantages of LCD projectors. If the result of the picture quality is vital to you, then the decision is a no-brainer. Take an LCD projector! LCD projectors will definitely make bright, colourful images with fewer image imperfections.

As the Dutch came to preeminence in sea power during the 17th century, the first yacht was a leisure craft used first by royalty and then by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private games. English yachting began with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting became popular with the wealthy and nobility, but after that time the fashion did not last.

The first yacht association in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held much naval panoply and formality. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, mostly as a social club, until 1765, and in 1828, when merging with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized method on the Thames around the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been started at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British racing. The club at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for large bets were held, and the club life was superlative. Ultimately Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was for the most part for pleasure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a benchmark of luxury and elegance for the later yachts in that area from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The craft of bigger yachts was first largely impacted by the victory of America, which was drawn by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. Early yachts were not designed and manufactured in the modern sense, with only a model being used. Not until the later half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the use of the research of aerodynamics do for the craft of sails and rigging what science had earlier done for hulls.

Because almost all sailboats had been individually built, there came a desire for handicapping boats before the one-design class boats were designed. Thus, a rating rule was written, which resulted in the International Rule, taken on in 1906 and edited in 1919. In modern times, one of the fastest flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to standard requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for such boats can be done on an even basis with no handicapping at all. A great example is the uniform International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

For the time that yachting was done largely for the royal and the rich, cost was no problem, and the size of boats grew, in both length and weight. The promotion and popularity of smaller yachts came in the later half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of smaller craft. Thereafter in the 20th century, notably after World War II, smaller racing and recreational craft became commonplace, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam started to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were employed more and more in pleasure yachts. Sizeable power yachts were progressed to a high standard, and long-distance sailing became a fond occupation of the well off. The early power yachts were paddle-wheel boats; they then made way to those powered by the completely submerged screw or propeller sort of propulsion. As well as naval and merchant vessels, auxiliaries possessing both sail and power were the yacht standard for many years. By the later half of the 20th century, several yachts were still auxiliaries, but the larger part were exclusively power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the manufacture of bigger steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of over 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As bigger and more dependable internal-combustion engines were developed, many large yachts started using them for power. The establishment of the diesel engine, using heavy oil for fuel, was furthered during World War I. In the decade that followed, big power-yacht creation flourished, reaching a climax in the Orion (1930) at 3,097 tons. During that time the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power yachts declined after 1932, and the fashion from then was toward smaller, less pricey yachts. After World War II, many small naval boats were traded by private owners for conversion to yachts. At the late 20th century, yachting is a widespread popular competition enjoyed by thousands of yachtsmen personally owning and maintaining their own small pleasure yachts. The popularity of boats and owners is increasing steadily, not only in the traditional areas on the seacoasts but also on inland waterways and lakes.

Taxes are differentiated by the effect they have on the allocation of income and wealth. A proportional tax is the kind of tax that impinges the same relative burden on every taxpayer—i.e., when tax liability and income move in relative proportion. A progressive tax is characterizable by a larger than proportional rise in the tax liability in regard to the rise in income, and a regressive tax is recognisable by a less than proportional growth in the comparative liability. Thus, progressive taxes are regarded as removing inequalities in income distribution, while regressive taxes are found to cause an increase in these inequalities.

The taxes that are often considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so within the upper-income categories—especially if a taxpayer is able to lessen his tax base by declaring deductions or by excluding particular income elements from his taxable income. Proportional tax rates when applied to lower-income demographics could also be more progressive if exemptions of a personal nature are declared.

Income measured over the period of a year may not necessarily provide the most accurate measure of taxpaying requirements. For example, transitory increases in income could be saved, and during temporary declines in income a taxpayer might select to pay for consumption by taking from savings. Ergo, if taxation is held in comparison along with “permanent income,” it should be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (with the exception of luxuries) are mostly regressive, because the spread of personal income consumed or spent on specific goods decreases as the amount of personal income grows. Poll taxes (also known as head taxes), nominated as a fixed amount per capita, clearly are regressive.

It is not simple to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends crucially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effects of taxation, it is important to differentiate between varied points of tax rates. The statutory rates will include those dictated in the law; generally these are marginal rates, but occasionally they are median rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income grows by one dollar. Ergo, if tax burden rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature often contain graduated marginal rates—i.e., rates that rise as income increases. Heavy analysis of marginal tax rates should review provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than indicated by the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for appraising incentive effects of taxation. It is even more complicated to understand the marginal effective tax rate to apply to income from business and capital, as it may be reliant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates signify the portion of total income that is required in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; on the flip side, preferential treatment of income received fundamentally by high-income households may dampen these effects, forcing regressivity, as shown by average tax rates that fall as income rises.

The LCDs utilised for projection systems are most often small reflective or transmissive panels illuminated by a bright arc lamp source. A series of lenses enlarges the reflected or transmitted image and displays it on a screen. In front-projection systems the LCD is located on the side of the screen as the viewer, but in rear-projection systems the screen is lit from behind. Projectors of more expense and performance can use three discrete LCD panels, reflecting separate red, green, and blue images that come together to reflect a coloured picture on the screen.

The increasing desire for pictographic presentations has put a growing emphasis on the switching speed of liquid crystals. This has demanded the development of objects employing smectic liquid crystals, particular types of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most sophisticated smectic device. In it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are on a tilt, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible consequence of the optical activity and the angle of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. So, there exists a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been publicized for bigger passive-matrix presentations, but their expensiveness and complexity has prevented them from enjoying any great progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick response allows them to be utilised in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pulsing (around 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods then to a nontransmissive state for the blue period, creating the outcome that the eye sees an average of red and green light, or the colour yellow.

From each of the furniture forms, the chair might be of most importance. While most other items (except the bed) are intended to support objects, the chair supports our human form. The term chair can be used here in the larger sense, from stool to throne to complex pieces including the bench and sofa, which can be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously labeled.

The social history of the chair is as interesting as its history as a creative art. The chair is not just a physical support and/or an aesthetic craft; it can also be an indicator of social rank. In the old royal courts there were significant connotations between being led to a chair with arms, or a chair with a back but no arms, or having to sit on a stool. During the 20th century, the director’s and/or manager’s chair has become an identifier of superior status, like in democratic parliaments the speaker sits on a higher floor.

In a furniture creation, the chair can be utilised for a range of different models. There are chairs manufactured to suit man’s age and physical capabilities (the high chair, the wheelchair) and for his position in society (the executive chair, the throne). During historical times there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs for ending life (the electric chair). We have chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Modern day living has designated particular chairs for use in automobiles and aircraft. All these chair kinds have perfected to suit to changing human uses. Because of its close connection with man, the chair lives to its full purpose only when used. Whereas it doesn’t make any difference to one’s appreciation of a cupboard or a dresser drawers whether there are items inside or not, a chair is really seen and judged best with a person utilising it, for chair and sitter require one another. Thus the various parts of a chair have been given names corresponding to the areas of our human body: arms, legs, feet, back, and seat.

Because the elemental job of the chair is to support a human body, its credit is judged basically by how fully it does measure up to this practical role. In the creation of a chair, the carpenter is limited within some static rules and principal measurements. Through these rules, however, the chair builder has large freedom.

The history of the chair extends over an era of several thousand years. There existed cultures that held distinctive chair types, as expressive of the leading task in the areas of handling and art. In those civilisations, particular mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of careful design, are now a finding from findings made in tombs. The first one of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs structured similar to those of a designated animal, a curved seat, and a sloping back supported from vertical stretchers. From this a durable triangular form was obtained. There was from our knowledge no significant difference between the construction of Egyptian thrones and chairs for regular non-royals. The simple variation lies in the type of ornamentation, in the selection of pricey inlays. The Egyptian folding stool in all likelihood was crafted for an easily stored seat for army soldiers. As a camp stool this type stayed until much later days. But the stool also then played the use of a ceremonial seat, its original job as a folding stool ignored or forgotten. This can from today be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are constructed in the construction of folding stools but are not able to be folded as the seats are formed of wood. The plain build of the folding stool, made of two frames that cycle on metal bolts and bear a seat of leather or fabric held between them, is seen at some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this form is the folding stool, made from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is known not from any ancient specimen still in form but found in a wealth of pictorial items. The most well known is the klismos placed on the Hegeso Stele at the Dipylon burial place just out of Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs are displayed. These odd legs were considered to be created with bent wood and were in that case subjected to huge pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore super solid and were overtly indicated.

The Romans embued the Greek chair; existing statues of seated Romans offer evidence of a thicker and in appearance kind of more crudely designed klismos. Both types, the light and heavy, were revived during the Classicist time. The klismos style is found in French Empire styles, in English Regency, and in some particular forms of notable uniqueness of Denmark and Sweden from 1800.

China
The past of the chair in China can not be tracked as well as the ancestry of chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed collection of images and artworks has been preserved, with images of the inside and exteriors of Chinese households and the designs of furniture. Also preserved since the 16th century are a collection of chairs constructed of wood or lacquered wood, that bear an intriguing likeness to pictures of past chairs.

Same as in Egypt, there were two standard chair forms in China: a chair of four legs and a folding stool. That chair can be constructed both with and without arms however never missing a square seat and straight stiles (upright side supports) to support the back. In one style, though, the stiles were slightly curved above the arms to sit right with the shape of the S-shaped back splat (the main upright of a back). Together, the three parts had been mortised in the yoke-like top rail. Despite that the idea of this back splat exercised a foundation for English chairs within the Queen Anne period, wooden members that could merely to a limited limit reinforce corner joints (and then are loose to top that off) indicate a design solely to Chinese chairs. The four legs are set through the seat frame, which ends over the rounded staves. Members are round in section or have rounded edges—references as may be to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited texture. These chairs required the sitter to stay stiff and upright; for when too much weight is exerted on the back, the chair has a way of toppling over. In patriarchal Chinese households of this period armchairs presumably were kept for the senior persons in the family, for they were held in great esteem.

The Chinese folding stool is understood to have taken to China from the West. It does not differ that much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is prettily affixed to the two legs of the stool by use of a curved member, which is usually designed with metal mounts. From a Western understanding the resulting effect of these two furniture forms is stylized. The constructive and aesthetic issues are combined in a manner that is at the same time naïve and refined. The patchwork appearance is a result of the manner that the individual parts do not appear to have been constructed by either glue or screws, but were mortised with one another and held in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its mark on the chair. Works of art show a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in the layers, stitched to bring out a pattern of little pads. The front board and a related board in the back could be folded after loosening some tiny iron hooks. In this way the chair was a portable piece of furniture in traveling which, at the same era, held the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is seen in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair can also be seen in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not certain that the innovation actually began in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slim dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was manufactured in large quantities, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up against a wall. The form asserts itself by its shapely proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, to say, as developed in Paris around 1750—spread over most of Europe and has been imitated or copied in the mid-20th century. The model owes the popularity to a combination of comfort and delicacy. The seat conforms to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions are made between seat frame, legs, and back cover all the joints, which are constructed solidly on craftsmanlike principles despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of rather thick density; but every member is deeply molded, all superfluous wood has been cut away, and more expensive chairs might be further embellished with special delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for the upholstery on the seat, back, and armrests; crosshatched cane is sometimes used as an alternative to upholstery.

English chairs from the 18th century were more open in design than the French. The French taste for stylistic uniformity, which came from the highest circles in Paris and Versailles within most of France and found favour in several parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became popular and was widely distributed throughout the world.

Late 18th to 20th century
Within the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

In cheaper styles of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, suggest that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recordkeeping of the money values of the transactions of a business. Bookkeeping creates the details from which accounts are drafted but is a previous process, preliminary to accounting.

Basically, bookkeeping grants two types of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking place in the business from a single period of time.

Management officials, investors, and credit grantors all need this information: management to analyse the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to analyse the upshot of business operations and make decisions for buying, holding, and selling securities; and credit grantors to regard the financial statements of an entity in judging whether to accept a loan.

Pieces of financial and numerical record charts can be seen for just about every nation with a commercial background. Records of commercial contracts have been uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been held in ancient Greece and Rome. The double-entry process of bookkeeping started with the development of the commercial republics of Italy, and tutorial manuals for bookkeeping were created within the 15th century in many Italian cities.

During the late 18th and early 19th centuries, the Industrial Revolution gave a notable stimulus to accounting and bookkeeping.

The progression of manufacturing, trading, shipping, and subsidiary services made accurate financial books a paramount factor. The history of bookkeeping, in fact, reflects closely the past of commerce, industry, and government and, partially, helped in forming it. The international movement of industrial and commercial activity demanded higher sophisticated decision-making methods, which in its turn required more sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government legislation became more important and resulted in even greater requirement for information; enterprises had to have available information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for their own inner departmental operations became larger.

Though bookkeeping processes can be rather complex, all of it is based on two styles of books employed in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger contains the records of individual accounts. The daily records kept in the journals are put in the ledgers.

At the end of every month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of the changes that took place in the enterprise equity because of the events of the period. The balance sheet gives the financial position of the enterprise at the particular point in time taken from assets, liabilities, and the ownership equity.

The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.

Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.

Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.

But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).

During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.

North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields produced an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful trend to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.
