The most common question that is asked when acquiring a new projector for the home, office, or classroom is: do I buy an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many brands and models available, it can be difficult for consumers to make a decision between these technologies. The simple fact of the matter is that LCD projectors give superior image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with reproducing the same standard of image quality.

Visualise a set of blinds in your house over your bedroom window. By a twist of a rod you can have the shutters open or closed, according to if you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel works like its own shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the image reaches your screen is extremely significant 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 send 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. A significant point to understad about LCD projectors is that all three colours are projected onto your projected surface all at once. The way a DLP projector functions is very different and even the produced image looks 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 approach to making 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 produce the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision will then pull together each coloured element of the image into the whole image. From LCD projectors, all colours are available all the time to offer the best brightness and spectacular colour accuracy. In DLP, only one colour is available at once, and so resulting in lower colour brightness and accuracy. Some DLP manufacturers have placed a white segment in the colour wheel to improve brightness generally, but this goes and degrades colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and as such must be superior. For those unaware, 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 machine is capable of. DLP projectors do possess high contrast specifications when compared to many LCD projectors. At one glance, this must be a benefit, however, in the real world, the true black level is determined by the ambient light in the room when the projector is being used. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you are trying to view has moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change up between the time red, blue and green colours are projected. LCD projectors do not have this characteristic because every colour is projected with the others. DLP designers have created 3DLP solutions using 3 chips to fix the colour break up artifacts, but the price of these projectors make them not practical for most businesses and consumers.

Another difference between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and recall how different colours of light refract varied amounts when directed through the same lens. The downside with DLP projectors is that they utilise the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light at different levels. Often with a DLP projector, some yellow colour will show above and some extra blue will appear below an image as simple as a lone black line. While being built LCD projectors can be adjusted to minimize these effects on the projected image, as each colour is projected on its own LCD panels.

The only actual advantage (excluding price) with taking a DLP projector is its smaller total size and weight. However, this is only relevant in regard to mobility and needs to be traded off against the image advantages of LCD projectors. If the result of the picture quality is important to you, then the answer is simple. Go for an LCD projector! LCD projectors will always create bright, colourful images with fewer image imperfections.

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht became a leisure craft used first by royalty and then by the burghers for the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting rose as fashionable for the rich and nobility, but after that period the fashion did not last.

The first yacht club in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had much naval panoply and formality. The closest thing to a race was the “chase,” for which the “fleet” pursued an imaginary enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, when merging with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered method on the Thames in the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed 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 site of British racing. The association at Cowes became the Royal Yachting Club, likewise at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing tests for great bets were held, and the society life was superlative. Eventually 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 continued when the English took control. Sailing was for the most part for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the style 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 sizeable yachts was originally largely impacted by the success of America, which was created by George Steers for a club started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. The first yachts were not designed and manufactured in a contemporary sense, with merely a model for an outline. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the application of the study of aerodynamics do for the craft of sails and rigging what such science had already done for hulls.

Because nearly all sailboats had been individually manufactured, there came a need for handicapping boats as this was before the one-design class boats were built. Hence, a rating rule was written, which is found in the International Rule, taken on in 1906 and edited in 1919. Today, one of the rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing such boats can be done on an even par with no handicapping at all. A perfect example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

For the time that yachting was an activity largely for the royal and the rich, expense was no object, and the size of boats grew, in both length and weight. The ascendancy and preference of smaller yachts occurred in the second 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of less sizeable boats. Thereafter in the 20th century, particularly after World War II, smaller racing and leisure boats became more popular, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, in which steam was set to replace sail power in commercial craft, the steam engine, and later the internal-combustion engine, were employed increasingly in pleasure craft. Sizeable power yachts were developed to a high standard, and long-distance travel was a fond pastime of the affluent. The earliest power yachts were paddle-wheel boats; these then made way to those powered by the wholly submerged screw or propeller kind of propulsion. As in the case of naval and merchant vessels, auxiliaries carrying both sail and power were the yacht fashion for several years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the majority were only power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the construction of bigger steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed 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 larger and more dependable internal-combustion engines were created, many bigger boats started using them for power. The development of the diesel engine, using heavy oil for fuel, progressed during World War I. In the decade following that, large power-yacht building flourished, hitting a climax in the Orion (1930) at 3,097 tons. From that time the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of big power craft fell away after 1932, and the trend after that was in preference of smaller, less pricey craft. After World War II, a lot of small naval vessels were bought by private owners for conversion to yachts. By the late 20th century, yachting had become a globally beloved competition enjoyed by thousands of yachtsmen personally manning and maintaining their own small pleasure yachts. The popularity of yachts and sailors increased steadily, not only in the traditional areas on the seacoasts but also on inland waterways and lakes.

Taxes can be differentiated by the impact they have on the allocation of income and wealth. A proportional tax is a kind that applies the same relative liability on all the taxpayers—i.e., in the case where tax liability and income move in the same levels. A progressive tax is recognisable by a more than proportional rise in the tax onus relative to the rise in income, and a regressive tax is recognised by a less than proportional increase in the related onus. Ergo, progressive taxes are viewed as removing a lack of equality in income distribution, while regressive taxes are believed to result in increasing these inequalities.

The taxes that are generally believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so in the upper-income class—especially if a taxpayer is able to reduce his tax base by nominating deductions or by leaving out particular income parts from his taxable income. Proportional tax rates if applied to lower-income classes would also be more progressive if personal exemptions are claimed.

Income measured over the period of a year does not definitely provide the most suitable measure of taxpaying status. For example, transitory rises in income can be saved, and during temporary declines in income a taxpayer could choose to finance consumption by decreasing savings. Therefore, if taxation is regarded along with “permanent income,” it would be less regressive (or more progressive) than when made comparable with annual income.

Sales taxes and excises (with the exception of those on luxuries) are mostly regressive, because the dissemination of individual income consumed or spent for a specific good decreases as the level of personal income grows. Poll taxes (also termed head taxes), levied as a fixed amount per capita, obviously are regressive.

It is complicated to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests for the most part on whether a national or a subnational (that is, provincial or state) tax is being determined.

In assessing the economic purpose of taxation, it is essential to distinguish between differing ideas of tax rates. The statutory rates include those nominated in the law; usually these are marginal rates, but in some cases they are average rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income increases by one dollar. Hence, if tax burden grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature usually contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates must take into account provisions as well as 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 nominated by the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the relevant ones for regarding incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, since it may be reliant on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the portion of total income that is paid 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 grows with income. Average income tax rates generally grow with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households might dampen these effects, allowing regressivity, as shown by average tax rates that lessen as income grows.

The LCDs utilised in projection systems are usually small reflective or transmissive panels set off by a powerful arc lamp source. A line of lenses magnifies the reflected or transmitted image and displays it onto the screen. For front-projection systems the LCD is placed on the side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of higher expense and capacity can utilise three separated LCD panels, casting separate red, green, and blue images that blend to make a coloured picture on the screen.

The growing desire for pictographic displays has put a growth in emphasis on the switching speed of liquid crystals. This has demanded the manufacture of items employing smectic liquid crystals, certain types of which emit a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. In it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as demonstrated in the figure. The host liquid crystal possesses optically active molecules, and a subtle turn up of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable 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. Hence, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up 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 in so doing reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark if one or more polarizers are used.

SSFLC devices have been produced for big passive-matrix displays, but their expense and intricacy has prevented them from enjoying any particular effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as parts in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be used in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid succession (about 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but then to a nontransmissive state for the blue period, displaying the end result that the eye sees an average of red and green light, or the colour yellow.

From each of the furniture needs, the chair may be of most importance. While many other objects (save for the bed) are meant to support objects, the chair supports a human form. The term chair should be used here in the widest sense, from stool to throne to further makes including a 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 overtly labeled.

The social history of the chair is as curious as its history as a creative art. The chair is not merely a physical support and/or an aesthetic artwork; it is historically a signifier of social hierarchy. At the Medieval royal courts there were clear signifiers between possessing a chair with arms, or a chair with a back but no arms, or worse having to utilise a stool. Since the 20th century, a director’s and/or manager’s chair has been an identifier of superior standing, and even in democratic government meeting the speaker sits on an elevated platform.

In its furniture creation, the chair is employed for a number of variations. There are chairs designed to attend to man’s age and physical capabilities (the high chair, the wheelchair) and to denote his position in society (the executive chair, the throne). From historical days there were chairs to be born in (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). We design 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, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated unique chairs in automobiles and aircraft. All these chair types have been changed to fit to different human uses. Because of its significant connection with man, the chair comes to its full advantage only when being utilised. While it isn’t relevant to one’s appreciation of a cupboard or a set of drawers whether there might be anything inside or not, a chair is understood best and fairly judged with a person sitting in it, because chair and sitter need the other. Thus the different areas of the chair have been given names corresponding to the elements of a human body: arms, legs, feet, back, and seat.

Because the clear job of the chair is to support a body, its value is tested basically by how suitably it does fulfill this practical function. In the design of the chair, the builder is limited by certain static law and principal measurements. Under these limitations, however, the chair maker has awesome freedom.

The history of the chair was a period of several thousand years. There is evidence of civilizations that had made significant chair forms, as seen of the leading object in the spheres of skill and creativity. Among these such societies, special note should 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of careful scheme, are now found from tombs. One of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs shaped like those of an animal, a curved seat, and a sloping back supported from vertical stretchers. In this design a strong triangular structure was created. There was to all appearances no notable differentiation in the construction of Egyptian thrones and chairs for ordinary non-royals. The main variation was in the complexity of ornamentation, in the particulars of more valuable inlays. The Egyptian folding stool in all probability was made as an easily packed seat for officers. As a camp stool this chair persisted for much later periods of time. But the stool also then played the use of a ceremonial seat, its technical role as a folding stool simply forgotten. This can from today be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but can not be folded because the seats were worked out of wood. The easy construction of the folding stool, consisting of two frames that cycle on metal bolts and have a seat of leather or fabric set between them, reappeared but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this type is the folding stool, made out of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not from any ancient item still existing but as found in a trove of pictorial objects. The best known is the klismos drawn on the Hegeso Stele at the Dipylon burial ground just out of Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of which are seen. These creative legs were probably crafted in bent wood and were therefore put under huge pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat were therefore super durable and were clearly indicated.

The Romans adopted the Greek chair; some casts of seated Romans display evidence of a thicker and which appear to be a kind of more crudely designed klismos. Both designs, the light and the heavy, were popularised during the Classicist epoch. The klismos design can be evidenced in French Empire design, in English Regency, and in special kinds of profound iconicism around Denmark and Sweden during 1800.

China
The ancestry of the chair in China is not able to be tracked as far back as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed folio of drawings and paintings was protected, displaying the interior and exterior of Chinese households and the designs of furniture. Also preserved since the 16th century are some chairs made from wood or lacquered wood, that possess an astonishing familiarity to representations of ancient chairs.

Just the same as in Egypt, there were two iconic chair designs in China: a chair that had four legs and a folding stool. This chair has been designed both with and without arms but always having the square seat and straight stiles (straight side supports) to hold up the back. In one image, it has been seen, the stiles had been delicately curved on top of the arms in order to conform to the shape of the S-shaped back splat (the centre upright of the back). Together, all three limbs were mortised on the yoke-like top rail. Though the style of this back splat then had a foundation for English chairs in the Queen Anne period, wooden sections that only to a restricted ability embolden corner joints (and furthermore are loose into the bargain) indicate a feature signatory to Chinese chairs. The four legs are set through the seat frame, which closes upon the rounded staves. All the members are round in section or have rounded edges—referable perchance to the bamboo tradition. The seat is uncomfortable and might have had a plaited texture. These chairs demanded of the sitter to hold themselves stiff and upright; when too much weight is exerted on the back, the chair has a tendency to topple. In patriarchal Chinese houses of this period armchairs likely were kept only for older members of the family, for they were held in great respect.

The Chinese folding stool is presumed to have taken to China from the West. It does not vary that much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is intricately affixed to the two legs of the stool by using a curved member, which is usually designed with metal mounts. From a Western understanding the ultimate effect of both these furniture forms is stylized. The construction and aesthetic issues are combined in a style that is at the same time naïve and refined. The pieced-together appearance is an upshot of the way that the individual parts do not appear to have been joined together by use of either glue or screws, but are mortised onto one another and held in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its signature on the chair. Paintings project a design of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between the layers, stitched to show up a pattern of small pads. The front board and a corresponding board from the back could be folded after loosening some small iron hooks. Therefore the chair was an easily portable piece of furniture while traveling which, during the same period, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is found in engravings of interiors of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair is also found in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not determined that the innovation actually was born in The Netherlands. Typically, the legs of the chair are smooth, round in section, and of slender dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in vast numbers, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up against a wall. The form asserts itself with its harmonious proportions and expensive upholstery in gilt leather or fabric framed with fringes.

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

French Rococo chairs and imitations of them are constructed from wood of relatively thick dimensions; but all the members are deeply molded, all extraneous wood has been removed, and finer chairs can be further embellished with intricately delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all the upholstery on the seat, back, and armrests; cane is in some cases used as an alternative to upholstery.

English chairs of the 18th century were more variable in form than the French. The French preference for stylistic uniformity, which spread from the highest circles in Paris and Versailles through most of France and was popular in large 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 reknowned 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 versions 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, hint 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 provides the information from which accounts are drafted but is a distinct process, prior to accounting.

Essentially, bookkeeping provides two types of information: (1) the current value, or equity, of the business and (2) the change in value—profit or loss—taking position in the entity within a particular period.

Management officials, investors, and credit grantors all demand this information: management so as to analyse the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to assess the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an enterprise in deciding whether to allow a loan.

Pieces of financial and numerical record charts can be found for nearly every society with a commercial history. Records of business contracts were uncovered in the archaelogy of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The double-entry manner of bookkeeping began with the development of the enterprising republics of Italy, and tutorials for bookkeeping were developed during the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a requirement. The ancestry of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in part, helped shaping it. The international movement of industrial and commercial activity called for more professional decision-making processes, which in its turn needed better sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government legislation became more significant and resulted in greater demand for information; enterprising firms had to have 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 grew in size, and the need for bookkeeping for their own departmental operations became larger.

While bookkeeping methods can be rather detailed, it is all based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger contains the records of individual accounts. The daily records from the journals are entered in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are created from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to show an analysis of those changes that took place in the ownership equity from the events of the period. The balance sheet shows the financial situation of the business at the particular day derived 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 yielded 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.
