The most common question customers ask when purchasing a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and different types available, it can be challenging for consumers to choose between these technologies. It comes down to the fact that LCD projectors provide far superior image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with creating a comparable rate of image quality.

Think of a set of blinds in your house over your bedroom window. By pulling on a rod you can make the shutters open or closed, depending on if you want to let light in or not. Such is exactly how an LCD projector works. Each pixel works like a unique 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 pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector is turned on to when the picture reaches your screen is ultimately significant to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by cutting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to deliver the projector image. Something important to know about LCD projectors is that all three colours are directed onto your screen simultaneously. The way a DLP projector functions is widely different and even the way an image appears is not the same. With DLP, white light from the lamp is directed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image creates a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to form the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into the single whole image. From LCD projectors, all colours are available all the time to create the top level of brightness and superb colour accuracy. In DLP, only one colour is available at once, causing lower colour brightness and accuracy. Some DLP manufacturers have put a white segment for the colour wheel to improve all over brightness, but this further lessens colour accuracy.

I find in forums all the time that DLP has a higher contrast ratio and thus must be better. For those who are uncertain, 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 technology is able to produce. DLP projectors do provide high contrast specifications compared to many LCD projectors. At first glance, this must be a benefit, however, in truth, the true black level is determined by the ambient light in the room where the projector is being used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to bring to life needs moving images, DLP projection technology can also have image marks, 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 change up between the time red, blue and green colours are pulled up. LCD projectors do not have this characteristic because all the colours are sent at the same time. DLP builders have developed 3DLP solutions using 3 chips to fix the colour break up artifacts, but the price tag of these projectors make them almost impossible for the majority of businesses and consumers.

Another difference between LCD and DLP is how they balance for the refractive qualities of light. Think back to high school science, and remember how various colours of light refract different amounts when passing through the same lens. The problem 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 different and refract light differently. Often with a DLP projector, an extra yellow colour will appear above and some extra blue will be projected below an image of something as simple as a straight black line. During manufacturing LCD projectors can be fixed to remove these effects on the projected image, because each colour is processed on isolated LCD panels.

The sole true benefit (excluding price) with picking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transport and must be traded off against the image benefits of LCD projectors. If overall picture quality is vital to you, then the answer is a no-brainer. Take an LCD projector! LCD projectors will always show bright, colourful images with fewer image errors.

As the Dutch came to dominance in sea power during the 17th century, the initial yacht was a pleasure craft used initially by royalty and then by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. 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 return to the English royalty 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, ruled 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting was found to be classy for the rich and royalty, but after that time the fashion did not last.

The first yacht club in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and held much naval panoply and formality. The closest thing to a race was the “chase,” when the “fleet” pursued an imagined enemy. The club went on, largely as a social club, until 1765, and in 1828, after joining with other societies, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some organized manner on the Thames around 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 with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht association 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 continuing location of British racing. The club at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing tests for great bids were held, and the club life was superlative. It came to be that the Royal Yachting Club boats increased 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 continued when the English had control. Sailing was largely for pleasure and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a standard of luxury and sophistication for the later yachts in the area from the late 19th century. The first continuing American yacht association, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The design of large yachts was initially largely put upon 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.) had its namesake after its victory at Cowes in 1851. Early yachts were not designed and built in the modern sense, with only a model being used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the application of the research of aerodynamics do for the craft of sails and rigging what such study had done earlier for hulls.

Because nearly all sailboats had to be individually custom-built, there arose a need for handicapping boats before the one-design class boats were designed. Thus, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the fastest growing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for these boats can be had on an even keel with no handicapping necessary. A great example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting was done primarily for the royal and the rich, expense was no issue, and the size of boats grew, in both length and weight. The ascendancy and preference of smaller boats happened in the second 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 journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the hardiness of less sizeable boats. Following this in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became commonplace, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, when steam began to emulate sail power in public vessels, the steam engine, and later the internal-combustion engine, were increasingly used in personal vessels. Bigger power yachts were progressed to a high degree, and long-distance travel became a preferred occupation of the affluent. The early power yachts were paddle-wheel boats; they then gave rise to boats powered by the wholly submerged screw or propeller kind of propulsion. As in the case of naval and merchant boats, auxiliaries possessing both sail and power were the yacht fashion for a number of years. By the later half of the 20th century, many yachts were still auxiliaries, but the majority were exclusively power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the construction of more sizeable steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 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 was used in active service for World War II.

As bigger and more dependable internal-combustion engines were produced, many bigger craft began using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed from World War I. During the decade after, big power-yacht creation blossomed, reaching a climax in the Orion (1930) at 3,097 tons. During that point the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power yachts declined after 1932, and the style after that was for smaller, less costly boats. After World War II, many small naval boats were traded by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally loved sport enjoyed by thousands of yachtsmen individually sailing and upkeeping their own small recreational craft. The popularity of craft 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 distribution of income and wealth. A proportional tax is the kind that impinges the same relative burden on each taxpayer—i.e., in the case where tax liability and income grow in the same scale. A progressive tax is characterized by a greater than proportional growth in the tax liability in relation to the rise in income, and a regressive tax is characterized by a less than proportional rise in the comparable liability. Thus, progressive taxes are seen as fighting inequity in income distribution, whereas regressive taxes are found to cause an increase in these inequalities.

The taxes that are generally considered progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, can become less so in the upper-income categories—especially if a taxpayer is able to lessen his tax base by declaring deductions or by excluding some certain income elements from his taxable income. Proportional tax rates if applied to lower-income categories will also be more progressive if personal exemptions are claimed.

Income measured over a given year does not absolutely offer the most accurate measure of taxpaying ability. For example, transitory growth in income may be saved, and in temporary declines in income a taxpayer may select to provide for consumption by reducing savings. Therefore, if taxation is regarded alongside “permanent income,” it can be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (with the exception of those on luxuries) tend to be regressive, because the dissemination of individual income consumed or spent for specific goods lowers as the level of personal income increases. Poll taxes (also called head taxes), nominated as a set amount per capita, patently are regressive.

It is hard to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden depends crucially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic purposes of taxation, it is important to distinguish between differing points of tax rates. The statutory rates are specified in legislation; commonly these are marginal rates, but occasionally they are mean rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income rises by one dollar. Thus, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that increase as income rises. Careful analysis of marginal tax rates are required to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points more than nominated within 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 necessary ones for appraising incentive effects of taxation. It is even more complicated to know the marginal effective tax rate applicable to income from business and capital, because it may be reliant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households might dwarf these effects, producing regressivity, as displayed by average tax rates that decrease as income increases.

The LCDs used in projection systems are most often small reflective or transmissive panels lit up by a forceful arc lamp source. A line of lenses enlarges the reflected or transmitted image and casts it on the screen. In front-projection systems the LCD is situated on the same area of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of higher expense and performance sometimes have three distinct LCD panels, creating separate red, green, and blue images that blend to create a coloured picture on the screen.

The increase in need for video displays has had a growth in emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices build with smectic liquid crystals, some types of which have a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most sophisticated smectic device. With it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal contains optically active molecules, and a subtle result of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Thus, there exists a permanent charge separation through 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 so reverse the tilt direction of the molecules. The consequential change in optical properties can make a change from light to dark when one or more polarizers are used.

SSFLC devices have been marketed for bigger passive-matrix presentations, but their high cost and complexity has prevented them from having any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some promise for use as elements in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be used in time-sequential colour systems, in which high cost colour filters are taken out for a coloured backlight that flashes red, green, and blue in rapid pulsing (about 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods and to a nontransmissive state in the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

Out of all furniture needs, the chair might be the primary one. While most other forms (save the bed) are designed to support objects, the chair supports a human form. The term chair can be used here in the most common sense, from stool to throne to complex items like a bench and sofa, which may be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinguished.

The social history of the chair is as stimulating as its history as an art and craft. The chair is not just a physical support or an aesthetic item; it can also be a symbol of social rank. Within the old royal courts there were social differences between being led to a chair with arms, or a chair with a back but without arms, and having to cope with a stool. During the recent century, a director’s and manager’s chair has been regarded as a signifier of superior standing, as well as in democratic government debate the speaker sits on a raised level.

In its furniture purpose, the chair is used for a range of various makes. There are chairs designed to attend to man’s age and physical abilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). During past days there were chairs for births (birth chairs); in the 20th century, there have been chairs for ending life (the electric chair). We have chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated special chairs for automobiles and aircraft. Each and every one of these chair forms have changed to match to differing human uses. Because of its unique relationship with man, the chair comes to its full advantage only when in employ. Although it is irrelevant to one’s appreciation of a cupboard or a bureau if there are things inside or not, a chair is really seen best and fairly judged by a person sitting on it, for chair and sitter require one another. Thus the various limbs of a chair were given labels like the limbs of a human body: arms, legs, feet, back, and seat.

Because the first work of the chair is to support the human body, its value is tested generally on how well it does fulfill this practical job. Within the creation of the chair, the designer is limited by particular static regulation and principal measurements. Within these limits, however, the chair designer has awesome freedom.

The history of the chair lasted dates of several thousand years. There are civilizations that had made iconic chair shapes, expressive of the leading task in the spheres of skill and creativity. From these such societies, a mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of expert make, were found from discoveries made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair had four legs crafted akin to those of some animal, a curved seat, leading to a sloping back supported by vertical stretchers. In this way a stable triangular design was obtained. There appears to be no notable variation from the design of Egyptian thrones and chairs for regular peasantry. The only change lies in the kind of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool in all likelihood was made for an easily carried seat for army soldiers. As a camp stool the form persisted during much later points. But the stool then also was made as the role of a ceremonial seat, its technical function as a folding stool fast forgotten. This can today be found, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the construction of folding stools but aren’t able to be folded because the seats are worked from wood. The easy construction of the folding stool, being of two frames that spin on metal bolts and support a seat of leather or fabric fastened between them, then came again some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of those is the folding stool, from ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not as any ancient fossil still in form but as in a trove of pictorial objects. The archetype is the klismos placed on the Hegeso Stele at the Dipylon burial ground near Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs were seen. These creative legs were most likely crafted in bent wood and were therefore had to bear huge pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat would have been therefore extremely solid and were overtly denoted.

The Romans borrowed from the Greek design; quite a few statues of seated Romans offer examples of a heavier and in appearance kind of more crudely crafted klismos. Both features, light and heavy, were seen again in the Classicist time. The klismos design is known in French Empire styles, in English Regency, and in some particular brands of marked uniqueness in Denmark and Sweden circa 1800.

China
The progression of the chair in China can not be followed as far back as in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged collection of sketches and artworks has been kept, with images of the interiors and outer parts of Chinese buildings and their furniture. Preserved also since the 16th century are a collection of chairs made of wood or lacquered wood, that show an intriguing likeness to styles of previous chairs.

Same as in Egypt, there were two fundamental chair forms in China: a chair having four legs and a folding stool. That four-legged chair is seen both with or without arms although always with a square seat and straight stiles (vertical side supports) to firm the back. In one form, though, the stiles had been marginally curved on top of the arms so as to suit the shape of the S-shaped back splat (the main upright of the back). Each of the three limbs had been mortised onto the yoke-like top rail. Despite that the style of a back splat then had an inspiration for English chairs in the Queen Anne period, wooden items that merely to a restricted extent stabilise corner joints (and are loose to top it off) signify a signature signatory to Chinese chairs. The four legs sit through the seat frame, which stops about the rounded staves. All members are round in section or possesses rounded edges—a left over perhaps to the bamboo tradition. The seat is uncomfortable and might have had a plaited bottom. These chairs demanded of the sitter to be stiff and upright; for when too much pressure is forced on the back, the chair has a tendency to topple. In patriarchal Chinese homes of this epoch armchairs probably were reserved for older persons in the family, for they were greatly esteemed.

The Chinese folding stool is presumed to have taken to China from the West. It does not vary much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is elegantly affixed to the two legs of the stool by a curved member, which is more often than not provided with metal mounts. From a Western understanding the resulting effect of both these furniture designs is stylized. The manufacture and aesthetic aspects are combined in a way that is all at once naïve and refined. The piecemeal appearance is an outcome of the manner that the individual members do not look to have been joined together by means of either glue or screws, but have been mortised with one another and held in position in the style of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered design of chair can be found in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the form actually was instigated in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of thin shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was manufactured in considerable amounts, as surmisable from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up against a wall. The style asserts itself by its elegant proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is to say, as brought out in Paris around 1750—disseminated through most of Europe and was imitated or copied into the mid-20th century. The style owes the popularity to a combination of leisure and elegance. The seat conforms to the human body and allows 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 covering the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are strongly constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of fairly thick dimensions; but each member is deeply molded, all superfluous wood has been taken away, and more expensive examples can be further embellished with intricately delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is generally used for all the upholstery on the seat, back, and armrests; cane is occasionally used rather than upholstery.

English chairs in the 18th century were more differentiated in style than the French. The French preference for stylistic uniformity, which spread from the most distinguished circles in Paris and Versailles within most of France and became the favourite 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 popularised and was widely distributed throughout the world.

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

In cheaper brands 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, purport that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping provides the numbers from which accounts are written but is a separate process, prior to accounting.

Basically, bookkeeping finds two parts of information: (1) the current value, or equity, of the entity and (2) the change in value—profit or loss—taking place in the entity during a singular period of time.

Management officials, investors, and credit grantors all have to have such information: management in order to understand the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to assess the outcome of business operations and make decisions for buying, holding, and selling securities; and credit grantors so as to judge the financial statements of an enterprise in judging whether to give a loan.

Pieces of financial and numerical recordkeeping have been uncovered for just about every group of people with a commercial history. Records of trading contracts have been discovered in the remains of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The dual-entry process of bookkeeping came with the progression of the business republics of Italy, and manuals for bookkeeping were developed within the 15th century in several Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial records a paramount factor. The past of bookkeeping, in fact, closely resembles the past of commerce, industry, and government and, in some part, helped in forming it. The international market of industrial and commercial activity needed greater cosmopolitan decision-making methods, which in turn needed better sophistication in the selection, classification, and presentation of information, more so with the assistance of computers. Taxation and government regulation became more detailed and resulted in greater requirement for information; business entities had to provide information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for their own operations increased.

Although bookkeeping methods can be very multifaceted, all are based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger must have the details of individual accounts. The daily records kept in the journals are entered in the ledgers.

At the end of every month, generally speaking, an income statement and a balance sheet are created from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of the changes that happen in the entity equity due to the transactions of the period. The balance sheet shows the financial position of the company at the particular day with regard to assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

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

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

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