The typical question that is asked when purchasing a new projector for the home, office, or classroom is: will 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 company brands and types available, it can be difficult for customers to decide between the two technologies. The fact is that LCD projectors provide far better image quality and colour accuracy. The article below will explain why DLP projectors struggle with creating a comparable grade of image quality.

Imagine a set of blinds in your household for your bedroom window. By twisting a rod you can turn the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel operates like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point at which the projector is turned on to when the picture reaches your screen is absolutely important for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which send the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to form the projector image. Something to understad about LCD projectors is that all three colours are sent onto your screen all at the same time. The way a DLP projector works is totally different and even how an image looks is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into a whole image. In LCD projectors, all colours are available all the time to deliver the best brightness and great colour accuracy. In DLP, only one colour is available at a time, and so resulting in lower colour brightness and accuracy. Some DLP manufacturers have included a white segment for the colour wheel to improve overall brightness, but this further degrades colour accuracy.

I see in forums all the time that DLP provides a higher contrast ratio and therefore must be better. 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. DLP projectors do offer high contrast specifications as compared to most LCD projectors. Initially, this can seem to be a plus, however, in truth, the true black level is determined by the ambient light in the room where the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you want to project includes moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images keep changing between the time red, blue and green colours are pulled up. LCD projectors do not have this disadvantage because every colour is sent with the others. DLP designers have developed 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price tag of these projectors make them almost impossible for the majority of businesses and consumers.

Another point of difference between LCD and DLP is how they match the balance for the refractive qualities of light. Remember back to high school science, and recall when they taught you how different colours of light refract varied amounts when passing through the same lens. The downfall with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light differently. Often with a DLP projector, an extra yellow colour will come up above and some blue will appear below an image of something as simple as a straight black line. While being built LCD projectors can be fixed to take away these effects on the projected image, as each colour is directed on separate LCD panels.

The only actual buy point (excluding price) with choosing a DLP projector is its smaller total size and weight. However, this is only relevant to portability and must be traded off against the image superiority of LCD projectors. If the result of the picture quality is important to you, then the solution is no-brainer. Take an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image blips.

As the Dutch came to preeminence in sea power during the 17th century, the initial yacht was a leisure craft used first by royalty and later by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam sent 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), made additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting became classy among the rich and aristocracy, but after that time the fashion did not last.

The first yacht association in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and had great naval panoply and rigour. The closest thing to racing was the “chase,” in which the “fleet” pursued a fictional enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, by joining with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it came to be 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 club 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 location of British racing. The club at Cowes became the Royal Yachting Club, likewise 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 bets were held, and the social life was wonderful. Eventually Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English held dominance. Sailing was largely for leisure and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens began 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 through to the second half of the 19th century. The style of sizeable yachts was initially heavily impacted by the success of America, which was created by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. Early yachts were not designed and built in a contemporary sense, with merely a model used. Not until the latter half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the employment of the research of aerodynamics do for the design of sails and rigging what science had previously 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. Therefore, a rating rule was decreed, which ended up in the International Rule, taken on in 1906 and amended in 1919. In the present day, one of the fastest blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to single requirements in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even keel with no handicapping necessary. A great example is the generic International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

As long as yachting was done largely for the royal and the affluent, expense was no object, and the size of boats increased, in both length and weight. The ascendancy and popularity of smaller boats occurred in the latter half of the 19th century out of 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 small boats. Later in the 20th century, for the larger part after World War II, smaller racing and leisure yachts became commonplace, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam began to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were favoured increasingly in leisure boats. Large power yachts were furthered to a high standard, and long-distance sailing turned into a fond occupation of the wealthy. The earliest power yachts were paddle-wheel boats; they then made way to boats powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the large part were solely power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a boom in the manufacture of large steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of at least 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 created, many large boats began using them for power. The development of the diesel engine, employing heavy oil for fuel, progressed in World War I. In the decade following, large power-yacht building blossomed, reaching a climax in the Orion (1930) at 3,097 tons. In that point the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power boats declined from 1932, and the style thereafter was in preference of smaller, less pricey yachts. From World War II, many small naval boats were traded by private owners for conversion to yachts. By the late 20th century, yachting is a widespread loved activity enjoyed by thousands of yachtsmen personally owning and keeping their own small recreational boats. The popularity of yachts and yachtsmen increased steadily, not only in the traditional locations by the beach but also on inland waterways and lakes.

Taxes can be categorized by the effect they have on the allocation of income and wealth. A proportional tax is the kind of tax that puts the same relative burden on every taxpayer—i.e., when tax liability and income grow in equal scale. A progressive tax is characterized by a larger than proportional rise in the tax liability in relation to the increase in income, and a regressive tax is recognisable by a less than proportional rise in the related burden. Therefore, progressive taxes are viewed as reducing a lack of equality in income distribution, whereas regressive taxes are found to result in an increase these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so for the upper-income categories—especially if a taxpayer is permitted to reduce his tax base by declaring deductions or by leaving out some income parts from his taxable income. Proportional tax rates that are applied to lower-income categories will also be more progressive if personal exemptions are made.

Income measured over the course of a given year may not necessarily provide the most accurate measure of taxpaying requirement. For example, transitory rises in income could be saved, and during temporary declines in income a taxpayer may decide to pay for consumption by reducing savings. So, if taxation is made comparable alongside “permanent income,” it can be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (with the exception of luxuries) are generally regressive, because the dissemination of personal income consumed or spent on specific goods lessens as the amount of personal income rises. Poll taxes (aka head taxes), nominated as a standard amount per capita, obviously are regressive.

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

In considering the economic effects of taxation, it is important to differentiate between varied concepts of tax rates. The statutory rates include those specified in the legislation; commonly these are marginal rates, but in some cases they are average rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income grows by one dollar. Thus, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that grow as income increases. Heavy analysis of marginal tax rates need to consider provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates indicate how after-tax income increases or decreases in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more complicated to nominate the marginal effective tax rate applied to income from business and capital, as it may rely on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the portion of total income that is taken in taxation. The pattern of average rates is the one that is necessary for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually increase with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; conversely, preferential treatment of income received for the most part by high-income households may swamp these effects, forcing regressivity, as displayed by average tax rates that lower as income rises.

The LCDs utilised in projection systems are generally small reflective or transmissive panels set off by a bright arc lamp source. A line of lenses magnifies the reflected or transmitted image and sends it on a screen. For front-projection systems the LCD is located on the same area of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of greater cost and capacity can be found with three distinct LCD panels, reflecting separate red, green, and blue images that blend to reflect a coloured picture on the screen.

The increasing desire for film displays has had a growing emphasis on the switching speed of liquid crystals. This has led to the development of devices employing smectic liquid crystals, some types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most complex smectic device. Inside it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and throughout the layers the molecules are tilted, as displayed in the figure. The host liquid crystal contains optically active molecules, and a slight outcome of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, similar 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 must be 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 in so doing reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark if one or more polarizers are employed.

SSFLC devices have been publicized for big passive-matrix presentations, but their high cost and intricacy has impeded them from creating any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reacting allows them to be used in time-sequential colour systems, in which expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick speed (approx 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods then to a nontransmissive state for the blue period, having the outcome that the eye sees an average of red and green light, or the colour yellow.

From all the furniture forms, the chair could be primary. While many other objects (apart from the bed) are intended to support objects, the chair supports your human form. The term chair should be viewed here in the most general sense, from stool to throne to derivative kinds including a bench or sofa, which can be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinuishable.

The social history of the chair is as intriguing as its history as an art and craft. The chair is not simply a physical support or aesthetic object; it can also be a signifier of social placement. In the past royal courts there were plain distinctions between being seated on a chair with arms, or a chair with a back but no arms, or having to use a stool. From the recent century, the director’s or manager’s chair has been seen as an indicator of superior status, like in democratic governments the speaker sits on an elevated level.

In a furniture construction, the chair is used for a number of various purposes. There are chairs designed to match man’s age and physical form (the high chair, the wheelchair) and for his rank in society (the executive chair, the throne). Since the olden days there were chairs to be born in (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We make 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 for easy storage, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs for automobiles and aircraft. Every one of these chair forms has been changed to fit to evolving human needs. For its unique importance with man, the chair appears to its full meaning only when being used. Whereas it doesn’t make any difference to one’s appreciation of a cupboard or a dresser drawers whether there might be items inside or not, a chair is understood and evaluated with a person using it, because chair and sitter suit the other. Thus the various parts of the chair have been labeled likened to the parts of the human form: arms, legs, feet, back, and seat.

Because the simple role of your chair is to support the body, its credit is judged basically by how well it does measure up to this practical purpose. In the build of the chair, the maker is bound by certain static rules and principal measurements. Inside these rules, however, the chair designer has marvellous freedom.

The history of the chair extends over an era of several thousand years. There are civilizations that held iconic chair types, as seen of the principal endeavour in the arenas of craft and creativity. Among these such civilisations, particular 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of careful design, are found from findings made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs crafted not unlike those of an animal, a curved seat, and leading to a sloping back supported over vertical stretchers. In this way a stable triangular construction was crafted. There appeared to be no particular differentiation in the structure of Egyptian thrones and chairs for ordinary populace. The simple change exists in the kind of ornamentation, in the particulars of costly inlays. The Egyptian folding stool in all probability was created as an easily carried seat for officers. As a camp stool the type stayed around until much later points in time. But the stool then also was designed as the role of a ceremonial seat, its mechanical history as a folding stool ignored or forgotten. This can today be found, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but are not able to be folded because the seats were formed with wood. The easy make of the folding stool, made of two frames that cycle on metal bolts and hold a seat of leather or fabric held between them, reappears but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of this kind is the folding stool, made of ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not with any ancient fossil still extant but as seen from a large amount of pictorial items. The most well known is the klismos displayed on the Hegeso Stele at the Dipylon burial ground by Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those could be displayed. These strange legs were understood to have been executed from bent wood and were probably put under huge pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore extremely stable and were plainly signified.

The Romans emulated the Greek chair; quite a few casts of seated Romans display examples of a denser and are a slightly less intricately constructed klismos. Both types, the light and the heavy, were seen again in the Classicist era. The klismos influence can be found in French Empire styles, in English Regency, and in special kinds of profound individuality around Denmark and Sweden circa 1800.

China
The progression of the chair in China isn’t able to be traced as long as the progression of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed folio of images and artworks had been preserved, showing the interior and outside of Chinese buildings and the designs of furniture. Another preservation of the 16th century are a trove of chairs constructed from wood or lacquered wood, that bear an astonishing familiarity to designs of past chairs.

Same as in Egypt, there were two iconic chair forms in China: a chair of four legs and a folding stool. The four-legged chair can be constructed both with or without arms however never missing its square seat and straight stiles (vertical side supports) to support the back. In one kind, however, the stiles are slightly curved above the arms so as to suit the shape of the S-shaped back splat (the centre upright of the chairback). Together, all three areas had been mortised in the yoke-like top rail. Though the style of a back splat later had an influence on English chairs within the Queen Anne period, wooden sections that would merely to a restricted limit support corner joints (and furthermore were loose as well) represent a design solely to Chinese chairs. The four legs sit through the seat frame, which closes upon the rounded staves. Each member is round in section or is given rounded edges—referable perhaps to the bamboo tradition. The seat is unpleasant to sit in and occasionally had a plaited seat. These chairs needed the sitter to be stiff and upright; if too much pressure is forced on the back, the chair has a way of toppling over. In patriarchal Chinese houses of this period armchairs most likely were only for senior people in the family, for they were greatly respected.

The Chinese folding stool is believed to have travelled to China from the West. It is akin much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is delicately held to the two legs of the stool by means of a curved member, which is generally possessing metal mounts. From a Western perspective the ultimate effect of these two furniture items is stylized. The constructive and aesthetic elements are combined in a way that is all at once naïve and refined. The pieced-together appearance is a result of the fact that the individual members do not appear to have been fixed by means of either glue or screws, but were mortised on one another and fixed in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Artworks display a design of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of tiny pads. The front board and a similar board from the back could be folded after loosening some tiny iron hooks. Therefore the chair was a readily portable piece of furniture while traveling which, at the same era, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair is evidenced in engravings of the inside of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not certain that the innovation actually was born in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of slender measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was crafted in vast quantities, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of these chairs lined up against a wall. The design asserts itself with its harmonious 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 created in Paris around 1750—spread over most of Europe and was imitated or copied in the mid-20th century. The style owes the popularity to a combination of comfort and charm. The seat adheres to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions are found between seat frame, legs, and back cover all the joints, which are constructed strongly on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof have wood of fairly thick measurements; but all the members are deeply molded, all superfluous wood has been cut away, and finer examples can be further embellished with highly delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; cane is occasionally used instead of upholstery.

English chairs of the 18th century were more open in form than the French. The French touch for stylistic uniformity, which lead from the most distinguished circles in Paris and Versailles over most of France and was popularised 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 popular and was widely distributed throughout the world.

Late 18th to 20th century
In 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 operation of a business. Bookkeeping grants the figures from which accounts are drafted but is a distinct process, prior to accounting.

Predominantly, bookkeeping grants two parts of information: (1) the current value, or equity, of an enterprise and (2) any changes in value—profit or loss—taking placement in the business from a singular period.

Management officials, investors, and credit grantors all demand this kind of information: management so as to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the outcomes of business operations and make decisions about buying, holding, and selling securities; and credit grantors to judge the financial statements of a business in assessing whether to accept a loan.

Traces of financial and numerical recordkeeping can be found for almost every country with a commercial history. Records of trading contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The dual-entry method of bookkeeping started with the progression of the enterprising republics of Italy, and tutorial manuals for bookkeeping were produced in the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial recordkeeping a requirement. The ancestry of bookkeeping, in fact, closely resembles the ancestry of commerce, industry, and government and, in part, helped to form it. The international revolution of industrial and commercial activity demanded greater sophisticated decision-making processes, which in its turn needed greater sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government legislature became more detailed and resulted in increased demand for information; entities had to show information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for departmental operations became higher.

While bookkeeping processes can be extremely complex, all are based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and such), and the ledger should have the record of individual accounts. The daily records kept in the journals are written in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to provide an analysis of any changes that took place in the entity equity resulting due to the operations of the period. The balance sheet provides the financial position of the entity at a particular day in terms of 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 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.
