The most common question that is asked when buying a new projector for the home, office, or classroom is: do I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most popular projector imaging technologies. With so many business brands and different types available, it can be difficult for clients to make a choice between both technologies. The simple fact of the matter is that LCD projectors provide superior image quality and colour accuracy. The article below will tell you why DLP projectors struggle with reproducing an equal rate of image quality.

Imagine a set of blinds in your room covering your bedroom window. By pulling 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 functions. Each pixel works like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as the 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 content reaches your screen is vitally significant to image quality, brightness and colour accuracy. LCD projectors direct 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 create the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. Something important to know about LCD projectors is that all three colours are delivered onto your wall at the same time. The way a DLP projector functions is very different and even how an image shows up is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming an image casts a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into the complete image. Using LCD projectors, all colours are available all the time to offer 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 designers have placed a white segment in the colour wheel to improve general brightness, but this then degrades colour accuracy.

I see in forums all the time that DLP gives a higher contrast ratio and therefore must be better. For those who are 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 system is capable of producing. DLP projectors do have high contrast specifications when compared to many LCD projectors. At a glance, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room where the projector is used. Do not be duped by contrast specifications on websites and in brochures.

When the content you are trying to view needs moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are shone. LCD projectors do not have this characteristic because all the colours are processed with the others. DLP designers have developed 3DLP solutions using 3 chips to solve the colour break up issue, but the price of these projectors make them hardly practical for the majority of businesses and consumers.

Another difference between LCD and DLP is how they balance for the refractive qualities of light. Take yourself back to high school science, and recall how various colours of light refract differing amounts when shone through the same lens. The downfall with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Generally with a DLP projector, an extra yellow colour will come up above and some blue will come up below something as simple as a straight black line. While being built LCD projectors can be fixed to remove these effects on the projected image, as each colour is processed on a separate LCD panels.

The only veritable plus (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant for portability and must be traded off against the image plusses of LCD projectors. If resulting picture quality is important to you, then the solution is easy. Take an LCD projector! LCD projectors will constantly make bright, colourful images with fewer image blips.

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht was a pleasure craft used initially by royalty and later by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting became popular with the rich and nobility, but after that period the habit did not last.

The first yacht association in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with much naval panoply and gravity. The closest thing to racing boats was the “chase,” in which the “fleet” pursued a fictional enemy. The club endured, mostly as a social club, until 1765, and in 1828, when conglomerating with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered fashion on the Thames about the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent - the strait between the mainland and the Isle of Wight - the perpetual site of British racing. The society at Cowes became the Royal Yachting Club, likewise at the rise of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing tests for large stakes were held, and the club life was splendid. Eventually Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English took power. Sailing was for the most part for leisure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a benchmark of luxury and sophistication for the later yachts in that area from the late 19th century. The first continuing American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of bigger yachts was initially largely affected by the victory of America, which was drawn by George Steers for a syndicate started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its win at Cowes in 1851. The first yachts were not designed and manufactured in the modern sense, with just a model being used. Not until the latter half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the employment of the science of aerodynamics do for the design of sails and rigging what such study had already done for hulls.

Because most of all sailboats had been individually built, there arose a desire for handicapping boats as this was previous to the one-design class boats were made. Hence, a rating rule came into being, which is found in the International Rule, taken on in 1906 and revised in 1919. Today, 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 created to standard specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between those boats can be had on an even playing field with no handicapping at all. A great example is the uniform International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting belonged largely for the nobility and the affluent, expense was no issue, and the size of boats grew, in both length and weight. The promotion and popularity of smaller yachts came 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 trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of smaller boats. Later in the 20th century, particularly after World War II, smaller racing and pleasure 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 traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, at which point steam was set to take the place of sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were favoured increasingly in leisure yachts. Sizeable power yachts were progressed to a high standard, and long-distance sailing became a preferred activity of the wealthy. The early power yachts were paddle-wheel boats; those then made way to those powered by the fully submerged screw or propeller sort of propulsion. As well as naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for many years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were solely power yachts that had gasoline or diesel engines.

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

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

The building of larger power yachts lessened from 1932, and the trend after that was for smaller, less expensive yachts. After World War II, lots of small naval vessels were sold to private owners for conversion to yachts. By the late 20th century, yachting had become a widespread loved activity enjoyed by thousands of yachtsmen who are actually owning and keeping their own small leisure yachts. The popularity of boats and yachtsmen increased steadily, not only in the traditional locations along the sea 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 one that imposes the same relative onus on all the taxpayers—i.e., in the case where tax liability and income grow in equal levels. A progressive tax is characterizable by a more than proportional growth in the tax liability relative to the growth in income, and a regressive tax is characterizable by a less than proportional growth in the comparative burden. Therefore, progressive taxes are regarded as removing the lack of equality in income distribution, but regressive taxes are seen to have the effect of increasing these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so within the upper-income group—in particular if a taxpayer is permitted to lessen his tax base by claiming deductions or by taking some income aspects from his taxable income. Proportional tax rates which are applied to lower-income demographics could also be more progressive if exemptions of a personal nature are claimed.

Income measured over a given year does not necessarily come up with the most appropriate measure of taxpaying status. For example, transitory increases in income might be saved, and in temporary declines in income a taxpayer could opt to pay for consumption by taking from savings. Therefore, if taxation is held in comparison with “permanent income,” it would be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are mostly regressive, because the dissemination of one’s income consumed or spent on specific goods declines as the rate of personal income increases. Poll taxes (also termed head taxes), nominated as a fixed amount per capita, patently are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic purpose of taxation, it is relevant to differentiate between several concepts of tax rates. The statutory rates include those specified in law; commonly these are marginal rates, but occasionally they are mean rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income rises by one dollar. Therefore, if tax liability increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that grow as income rises. Careful analysis of marginal tax rates need to regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points greater than nominated within the statutory rates. Since marginal rates specify how after-tax income moves in response to changes in before-tax income, they are the important ones for regarding incentive effects of taxation. It is even more difficult to know the marginal effective tax rate to apply to income from business and capital, because it may depend on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates display the part of total income that is required in taxation. The pattern of average rates is the one that is necessary for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly increase with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received mostly by high-income households can swamp these effects, forcing regressivity, as indicated by average tax rates that decline as income grows.

The LCDs used for projection systems are most often small reflective or transmissive panels lit by a strong arc lamp source. A series of lenses expands the reflected or transmitted image then casts it onto a screen. In front-projection systems the LCD is set on the same side of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of higher expense and performance can use three distinct LCD panels, creating separate red, green, and blue images that combine to reflect a coloured picture on the screen.

The increasing requirement for pictographic displays has placed a special emphasis on the switching speed of liquid crystals. This has required the invention of objects using smectic liquid crystals, particular types of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. In it the liquid crystal molecules are set out in perpendicular layers to the substrate planes, which are separated by one or two micrometres, and within the layers the molecules are on a tilt, as displayed in the figure. The host liquid crystal has optically active molecules, and a subtle outcome of the optical activity and the shape 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 within the plane of the layers. Therefore, there must be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix displays, but their expensiveness and intricacy has impeded them from creating any significant effect 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 fast responding allows them to be used in time-sequential colour systems, in which dear colour filters are replaced by a coloured backlight that flashes red, green, and blue in quick pulsing (approximately 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods then to a nontransmissive state in the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

Out of each of the furniture items, the chair may be the imperative one. While most other items (apart from the bed) are intended to support objects, the chair supports our human form. The term chair can be regarded here in the most open sense, from stool to throne to complex forms including the bench and sofa, which should be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly defined.

The social history of the chair is as interesting as its history as an art and craft. The chair is not merely a physical support and/or an aesthetic creation; it historically is semiotic of social ranking. From the past royal courts there were important signifiers between being led to a chair with arms, on a chair with a back but without arms, and having to cope with a stool. From the 20th century, the director’s and manager’s chair has been regarded as iconic of superior standing, and even in democratic parliaments the speaker sits on a raised level.

In a furniture purpose, the chair can be employed for a wealth of various models. There are chairs designed to attend to man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his standing in society (the executive chair, the throne). Since historical days there were chairs for birthing (birth chairs); during the 20th century, there have been chairs used for ending life (the electric chair). There are 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 modern lifestyle has developed particular chairs for automobiles and aircraft. Each of these chair kinds has been changed to suit to growing human needs. For its significant importance with man, the chair comes to its full significance only when utilised. Though it makes no difference to one’s appreciation of a cupboard or a set of drawers if there are things inside or not, a chair is really seen best and fairly regarded by a person sitting on it, because chair and sitter require each other. Thus the several limbs of the chair have been labeled according to the names of our human shape: arms, legs, feet, back, and seat.

Because the obvious function of your chair is to support your body, its credit is valued principally on how fully it does fulfill this practical role. Within the design of the chair, the builder is bound under particular static regulations and principal measurements. Under these limitations, however, the chair designer has marvellous freedom.

The history of the chair covers an era of several thousand years. There were cultures that had made iconic chair forms, expressive of the premier craft in the arenas of craft and aesthetics. Within these peoples, individual note needs to 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 items of skilled design, are seen from tomb discoveries. One of these two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs crafted like those of some animal, a curved seat, and a sloping back supported with vertical stretchers. In this design a stable triangular design was created. There was apparently no significant difference from the structure of Egyptian thrones and chairs for common populace. The real difference lies in the decorative ornamentation, in the particulars of more costly inlays. The Egyptian folding stool in all likelihood was crafted as an easily portable seat for officers. As a camp stool the type continued during much later periods of time. But the stool then also was created as the task of a ceremonial seat, its original history as a folding stool fast forgotten. This can from today’s evidence be seen, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are made in the shape of folding stools but aren’t able to be folded because the seats are formed from wood. The simple build of the folding stool, being of two frames that turn on metal bolts and support a seat of leather or fabric set between them, reappeared but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this type is the folding stool, made from ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is recognised not as any ancient specimen still around but in a large amount of pictorial objects. The most recognisable is the klismos placed on the Hegeso Stele at the Dipylon burial location outside Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs can be displayed. These unusual legs were thought to have been crafted in bent wood and were probably bore a large amount of pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore super stable and were particularly drawn.

The Romans adopted the Greek designs; designs of models of seated Romans display examples of a more heavyset and are a somewhat less intricately constructed klismos. Both features, the light or heavy, were brought back during the Classicist era. The klismos chair can be evidenced in French Empire chairs, in English Regency, and in special brands of considerable iconicism within Denmark and Sweden from 1800.

China
The past of the chair in China is not able to be traced as long as that of Egypt and Greece. Since the Tang dynasty (AD 618–907) a full collection of images and paintings had been protected, displaying the insides and exterior of Chinese households and the furniture. Kept also from the 16th century are some chairs made of wood or lacquered wood, that bear an intriguing resemblance to pictures of previous chairs.

Same as in Egypt, two chair designs persisted in China: a chair with four legs and a folding stool. This chair can be seen both with or without arms but always with a square seat and straight stiles (upright side supports) to support the back. In one kind, it has been seen, the stiles could be lightly curved over the arms to suit the form of the S-shaped back splat (the centre upright of its chairback). The three sections had been mortised on the yoke-like top rail. Despite that the idea of the Chinese back splat exercised an inspiration for English chairs of the Queen Anne period, wooden sections that only to a particular extent reinforce corner joints (as well as being loose in the bargain) represent a design particular to Chinese chairs. The four legs pass through the seat frame, which finishes over the rounded staves. All members are round in section or is given rounded edges—acknowledging perhaps to the bamboo tradition. The seat is not comfortable and occasionally had a plaited texture. These chairs required of the sitter to be stiff and upright; if too much pressure is placed on the back, the chair has a tendency to collapse. In patriarchal Chinese households of this epoch armchairs most likely were kept only for senior family members, for they were held in great respect.

The Chinese folding stool is believed to have come to China from the West. It is akin so very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is prettily joined to the two legs of the stool with a curved member, which is often provided with metal mounts. From a Western understanding the ultimate effect of these furniture styles is stylized. The manufacture and decoration parts are combined in a way that is at the same time naïve and refined. The pieced-together appearance is an outcome of the way that the individual parts do not appear to have been fixed together with either glue or screws, but are mortised on one another and fixed in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its signature on the chair. Works of art show a design 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 show up a pattern of small pads. The front board and a related board at the back could be folded after unscrewing some small iron hooks. Thus the chair was a readily portable piece of furniture while traveling which, at the same period, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this design of chair may also be seen in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not held that the design actually was instigated in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in vast numbers, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up against a wall. The style asserts itself by its elegant proportions and delicate 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 developed in Paris around 1750—disseminated through most of Europe and was imitated or copied into the mid-20th century. The chair owes this popularity to a combination of leisure and charm. The seat conforms to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Typically 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 cover all the joints, which are stable, constructed on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are constructed from wood of quite thick measurements; but all members are deeply molded, all superfluous wood has been cut away, and more upmarket chairs can be further embellished with very delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; canework is in some cases used instead of upholstery.

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

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

Basically, bookkeeping grants two kinds 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 over a single time.

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

Bits and pieces of financial and numerical recordkeeping are found for nearly every nation with a commercial background. Records of business contracts have been found in the archaelogy of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The double-entry manner of bookkeeping began with the development of the enterprising republics of Italy, and instruction books for bookkeeping were produced in the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made perfect financial books a requirement. The history of bookkeeping, in fact, resembles the past of commerce, industry, and government and, partially, assisted to shape it. The worldwide revolution of industrial and commercial activity demanded higher sophisticated decision-making methodology, which itself called for more sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government regulation became more important and resulted in higher demand for information; business 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 grew, and the need for bookkeeping for their inner departmental operations went up.

Although bookkeeping methods can be extremely detailed, all are based on two types of books employed in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger must have the details of individual accounts. The daily records from the journals are entered in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are made from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to show an analysis of those changes that have occurred in the business equity resulting from the operations of the period. The balance sheet shows the financial condition of the business at any particular point in time regarding assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful 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.
