The typical question heard when buying a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most popular projector imaging technologies. With so many brands and different models available, it can be confusing for consumers to decide between those technologies. Ultimately LCD projectors give far superior image quality and colour accuracy. The article below will tell you why DLP projectors struggle with projecting a similar rate of image quality.

Think of a set of blinds in your household covering your bedroom window. By pulling a rod you can make the shutters open or closed, depending on whether you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel operates like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point at which the projector is switched on to when the image reaches your screen is absolutely significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by cutting it into red, blue and green components, by three mirrors which project the coloured light to 3 separate LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. Something important to remember about LCD projectors is that all three colours are sent onto your projected surface all at once. The way a DLP projector runs is widely different and even the produced image shows up is not the same. With DLP, white light from the lamp is sent through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image creates a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to form the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into a complete image. In LCD projectors, all colours are available all the time to deliver the top level of brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP developers have added a white segment for the colour wheel to improve brightness generally, but this further degrades colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and as such must be superior. For those who don’t know, 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 system is capable of producing. DLP projectors do offer high contrast specifications compared to many LCD projectors. Initially, this appears to be an advantage, however, in truth, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you are trying to project needs moving images, DLP projection technology also has image marks, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change up between the time red, blue and green colours are shone. LCD projectors do not have this problem because every colour is projected at the same time. DLP builders have come up with 3DLP solutions using 3 chips to fix the colour break up error, but the expense of these projectors make them almost impossible for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Take yourself back to high school science, and recall when they taught you how the various colours of light refract varied amounts when shone through the same lens. The disadvantage with DLP projectors is that they have the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Most of the time with a DLP projector, a superfluous yellow colour will appear above and some blue will show below an image of something as simple as a lone black line. During manufacturing LCD projectors can be set to minimize these effects on the projected image, as each colour is refracted on isolated LCD panels.

The one actual buy point (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant with regard to transport and needs to be traded off against the image benefits of LCD projectors. If resulting picture quality is important to you, then the solution is easy. Take an LCD projector! LCD projectors will definitely make bright, colourful images with fewer image mistakes.

As the Dutch came to dominance in sea power during the 17th century, the early yacht had been a pleasure 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 matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure 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 more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting rose as fashionable among the affluent and nobility, but after that time the trend did not last.

The first yacht group in the British Isles, the Water Club, was started at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held large naval panoply and gravity. The closest thing to racing was the “chase,” in which the “fleet” pursued a fictional enemy. The club went on, for the large part as a social club, until 1765, and in 1828, by conglomerating with other clubs, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized method on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it was named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the continued setting of British yacht racing. The club at Cowes became the Royal Yachting Club, also at the accession of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for high stakes were held, and the social life was wonderful. Ultimately Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English had control. Sailing was largely for fun and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The design of bigger yachts was initially greatly impacted by the victory of America, which was drawn by George Steers for a association headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. The first yachts were not designed and crafted in a contemporary sense, with just a model for an outline. Not until the second half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the employment of the research of aerodynamics do for the craft of sails and rigging what such science had already done for hulls.

Because almost all sailboats had to be individually custom-built, there arose a need for handicapping boats as this was before the one-design class boats were built. Thus, a rating rule was created, which resulted in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the most rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard specifications in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even par with no handicapping at all. A perfect example is the uniform International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

As long as yachting belonged largely for the aristocracy and the wealthy, money was no problem, and the size of boats increased, in both length and weight. The ascendancy and desire of smaller boats occurred in the latter half of the 19th century in 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of small boats. Following this in the 20th century, for the larger part after World War II, smaller racing and recreational craft became more common, down to the dinghy, a favourite 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
Post the decade 1840–50, in which steam was set to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure vessels. Bigger power yachts were progressed to a high element, and long-distance travel was a preferred pastime of the rich. The first power yachts were paddle-wheel boats; they then gave way to boats powered by the completely submerged screw or propeller kind of propulsion. Like naval and merchant boats, auxiliaries possessing both sail and power were the yacht fashion for several years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

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

As larger and more dependable internal-combustion engines were created, many large yachts started using them for power. The establishment of the diesel engine, using heavy oil for fuel, was furthered for World War I. During the decade after that, big power-yacht building flourished, hitting a climax in the Orion (1930) at 3,097 tons. During that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power boats declined after 1932, and the trend from then was for smaller, less expensive boats. From World War II, many small naval craft were traded by private owners for conversion to yachts. By the late 20th century, yachting has become a widespread popular competition enjoyed by thousands of yachtsmen who are actually manning and keeping their own small recreational craft. The popularity of yachts and owners is increasing steadily, not only in the traditional places by the seacoasts but also on inland waterways and lakes.

Taxes can be distinguished by the effect they have on the allocation of income and wealth. A proportional tax is a tax that applies the same relative burden on each taxpayer—i.e., when tax liability and income move in equal levels. A progressive tax is recognisable by a greater than proportional growth in the tax burden relative to the rise in income, and a regressive tax is characterizable by a less than proportional increase in the comparable burden. So, progressive taxes are seen as taking away inequity in income distribution, whereas regressive taxes are found to cause an increase in these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, might become less so in the upper-income group—in particular if a taxpayer is permitted to reduce his tax base by nominating deductions or by excluding some income aspects from his taxable income. Proportional tax rates that are applied to lower-income groups can also be more progressive if personal exemptions are declared.

Income measured over the course of a given period might not necessarily give the most accurate measure of taxpaying status. For example, transitory growth in income may be saved, and during temporary declines in income a taxpayer could select to finance consumption by decreasing savings. Ergo, if taxation is made comparable along with “permanent income,” it will be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are usually regressive, because the dissemination of one’s income consumed or spent on specific goods lessens as the level of personal income increases. Poll taxes (aka head taxes), calculated as a fixed amount per capita, obviously are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden rests essentially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In assessing the economic purposes of taxation, it is important to distinguish between varied ideas of tax rates. The statutory rates will include those specified in legislature; generally these are marginal rates, but sometimes they are mean rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income rises by one dollar. Therefore, if tax onus rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates should review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points higher than nominated within the statutory rates. Since marginal rates specify how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applicable to income from business and capital, as it may depend on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates display the percentage of total income that is required in taxation. The pattern of average rates is the one that is in consideration for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually increase with income, both because personal allowances are permitted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households can dwarf these effects, forcing regressivity, as displayed by average tax rates that lessen as income rises.

The LCDs built for projection systems are typically small reflective or transmissive panels lit up by a forceful arc lamp source. A number of lenses enlarges the reflected or transmitted image and then displays it on the screen. For front-projection systems the LCD is situated on the side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of more expense and performance may have three separate LCD panels, forming separate red, green, and blue images that mesh to create a coloured picture on the screen.

The growing need for pictographic presentations has placed a growth in emphasis on the switching speed of liquid crystals. This has required the development of items using smectic liquid crystals, particular types of which give a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. Inside it the liquid crystal molecules are managed in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the angle of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. So, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark when one or more polarizers are used.

SSFLC devices have been publicized for large passive-matrix displays, but their expensiveness and complexity has prevented them from having any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate response allows them to be used in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast pulsing (approximately 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods and then to a nontransmissive state for the blue period, with the result that the eye sees an average of red and green light, or the colour yellow.

Out of all furniture objects, the chair might be the most imperative. While most other objects (save for the bed) are created to support objects, the chair supports a human form. The term chair should be looked upon here in the larger sense, from stool to throne to further items including a bench and sofa, which might be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously defined.

The social history of the chair is as curious as its history as a creative art. The chair is not simply a physical support and aesthetic creation; it is also semiotic of social standing. In the past royal courts there were important differences between having a chair with arms, or a chair with a back but without arms, and having to use a stool. During the recent century, the director’s and manager’s chair has been a signifier of superior rank, as well as in democratic governments the speaker sits on an elevated platform.

In its furniture form, the chair is utilised for a variety of different forms. There are chairs structured to match man’s age and physical condition (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). During the olden days there were chairs for birthing (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed special chairs for automobiles and aircraft. All these chair forms have been adapted to match to different human uses. Due to its significant relationship with man, the chair lives to its full purpose only when used. Although it doesn’t make a difference to one’s appreciation of a cupboard or a set of drawers whether there might be items inside or not, a chair is best seen and judged best with a person sitting in it, for chair and sitter require the other. Thus the individual parts of a chair are given names likened to the areas of the human shape: arms, legs, feet, back, and seat.

Because the principal purpose of the chair is to support the body, its credit is valued firstly from how well it measures up to this practical function. Within the manufacture of the chair, the maker is bound within the static laws and principal measurements. Through these limitations, however, the chair designer has great freedom.

The history of the chair lasts over an epoch of several thousand years. There were civilizations that have created distinctive chair forms, seen of the highest endeavour in the industries of handling and creativity. In such peoples, individual mention can 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of expert scheme, were known from findings made in tombs. The first of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs formed not unlike those of a designated animal, a curved seat, and a sloping back supported by vertical stretchers. From this a durable triangular construction was crafted. There seems to be no marked change between the structure of Egyptian thrones and chairs for ordinary peasantry. The real difference was in the complex ornamentation, in the evidence of more costly inlays. The Egyptian folding stool most probably was designed to be an easily carried seat for officers. As a camp stool this chair stayed during much later periods. But the stool then also was created as the use of a ceremonial seat, its mechanical function as a folding stool ignored or forgotten. This can from today’s evidence be seen, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but are not able to be folded because the seats are formed out of wood. The plain manufacture of the folding stool, composed of two frames that turn on metal bolts and support a seat of leather or fabric set between them, can be seen but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this kind is the folding stool, made out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is known not as any ancient object still extant but found in a wealth of pictorial evidence. The archetype is the klismos drawn on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those would be displayed. These strange legs were most likely to be manufactured with bent wood and were thus subjected to a large amount of pressure under the weight of the sitter. The joints holding the legs to the frame of the seat had to be therefore very strong and were visibly drawn.

The Romans emulated the Greek style; some models of seated Romans offer designs of a more heavyset and in appearance rather crudely built klismos. Both styles, light or heavy, were revived in the Classicist epoch. The klismos style is known in French Empire chairs, in English Regency, and in some particular forms of notable uniqueness around Denmark and Sweden around 1800.

China
The ancestry of the chair in China is not able to be followed as far as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed collection of drawings and artworks has been kept, showing the interior and exteriors of Chinese households and their furniture. Also preserved of the 16th century are a trove of chairs made of wood or lacquered wood, that display an astonishing resemblance to representations of ancient chairs.

As were the designs in Egypt, two iconic chair forms existed in China: a chair of four legs and a folding stool. That chair was designed both with and without arms however never missing the square seat and straight stiles (standing side supports) to firm the back. In one image, however, the stiles were slightly curved over the arms so as to conform to the angle of the S-shaped back splat (the central upright of the back). The three limbs are mortised into the yoke-like top rail. Though the idea of a back splat had an introduction for English chairs during the Queen Anne period, wooden members that just to a limited ability stabilise corner joints (and are loose to top it off) are a feature solely to Chinese chairs. The four legs are set through the seat frame, which closes about the rounded staves. All the members are round in section or possesses rounded edges—an acknowledgement maybe to the bamboo tradition. The seat is not pleasant and may have a plaited seat. These chairs required of the sitter to remain stiff and upright; for if too much weight is exerted on the back, the chair has a tendency to collapse. In patriarchal Chinese households of this epoch armchairs probably were kept only for older people, for they were respected greatly.

The Chinese folding stool is understood to have come to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it has a difference in that the top rail is delicately affixed to the two legs of the stool by means of a curved member, which is often seen with metal mounts. From a Western understanding the ultimate effect of both these furniture designs is stylized. The construction and decorative issues are combined in a manner that is both naïve and refined. The piecemeal appearance is a result of the way that the individual items do not appear to have been constructed by means of either glue or screws, but are mortised on one another and fixed in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its name on the chair. Artworks show a type of chair with a relatively unrefined wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between, stitched to produce a pattern of small pads. The front board and a related board in the back could be folded after unscrewing some small iron hooks. Therefore the chair was a portable piece of furniture when traveling which, in the same era, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is evidenced in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the style actually began in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in vast amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up along a wall. The form asserts itself by virtue of 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 style—that is, as developed in Paris around 1750—conquered most of Europe and has been imitated or copied during the mid-20th century. The style owes the popularity to a combination of leisure and charm. The seat conforms to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are tiny upholstered pads on the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed solidly on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of rather thick dimensions; but each member is deeply molded, all superfluous wood has been sanded away, and more upmarket items can be further embellished with highly delicate and decorative engraving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used rather than upholstery.

English chairs of the 18th century were more varied in design than the French. The French manner for stylistic uniformity, which came from the highest circles in Paris and Versailles over 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 commonly known and was widely distributed throughout the world.

Late 18th to 20th century
During 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, indicate that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping gives the figures from which accounts are prepared but is a separate process, preliminary to accounting.

Predominantly, bookkeeping records two parts of information: (1) the current value, or equity, of the entity and (2) changes in value—profit or loss—taking placement in the entity from a singular time period.

Management officials, investors, and credit grantors all require this information: management to interpret the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an entity in finding whether to give a loan.

Bits and pieces of financial and numerical record charts are seen for almost every state with a commercial backbone. Records of trading contracts have been uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The dual-entry way of bookkeeping started with the furthering of the entrepeneurial republics of Italy, and manuals for bookkeeping were produced within the 15th century in some Italian cities.

Within the late 18th and early 19th centuries, the Industrial Revolution permitted an important stimulus to accounting and bookkeeping.

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial records a requirement. The ancestry of bookkeeping, in fact, resembles closely the history of commerce, industry, and government and, partially, assisted to shape it. The international spread of industrial and commercial activity demanded greater professional decision-making methods, which in its turn needed greater sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government regulation became more important and resulted in even greater need for information; entities had to show available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the demand for bookkeeping for their inner operations increased.

Though bookkeeping procedures can be rather multifaceted, it is all based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, etcetera), and the ledger must have the record of individual accounts. The daily records kept in the journals are entered in the ledgers.

Each month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of any changes that happen in the enterprise equity resulting from the operations of the period. The balance sheet shows the financial condition of the corporation at any particular date regarding 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 resulted in 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 wish 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.
