The typical question asked when acquiring a new projector for the home, office, or classroom is: should I take an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many brands and models available, it can be difficult for consumers to make a decision between these technologies. It comes down to the fact that LCD projectors provide far better image quality and colour accuracy. The next part of this article will explain why DLP projectors struggle with reproducing the same level of image quality.

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

How the light source is processed from the point at which the projector switches on to when the picture reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by shining each pixel on and off. The pixels are then meshed in a glass prism to form the projector image. A significant point to remember about LCD projectors is that all three colours are projected onto your screen all at the same time. The way a DLP projector runs is totally different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to construct the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then pull together each coloured element of the image into the full image. Using LCD projectors, all colours are available all the time to form high brightness and superb colour accuracy. In DLP, only one colour is available at once, and so causing lower colour brightness and accuracy. Some developers have placed a white segment into the colour wheel to improve brightness generally, but this further damages colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and thus must be superior. For those who don’t know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is able to produce. DLP projectors do provide high contrast specifications as compared to the majority of LCD projectors. At one glance, this seems to be an advantage, however, in reality, the true black level is determined by the ambient light in the room where the projector is being used. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you plan to view needs moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most common artifact that a DLP projector forms with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are shone. LCD projectors do not have this disadvantage because the colours are projected at the same time. DLP developers have created 3DLP solutions using 3 chips to fix the colour break up problem, but the expense of these projectors make them not practical for most businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember how different colours of light refract differing amounts when passing through the same lens. The downside with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Usually with a DLP projector, a superfluous yellow colour will come up above and some blue will show below an image as simple as a straight black line. In building LCD projectors can be set to remove these effects on the projected image, because each colour is processed on its own LCD panels.

The sole real buy point (excluding price) with picking a DLP projector is its smaller overall size and weight. However, this is only relevant with regard to mobility and has to be traded off against the image superiority of LCD projectors. If the result of the picture quality is vital to you, then the solution is a no-brainer. Go for an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image errors.

As the Dutch came to preeminence in sea power during the 17th century, the early yacht had been a leisure craft used first by royalty and secondly by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure 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 additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting became classy for the affluent and nobility, but after that time the fashion did not last.

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

Yacht racing was first seen in some organized manner on the Thames around the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British racing. The organisation at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing matches for great stakes were held, and the social life was wonderful. It came to be that the Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English gained control. Sailing was mostly for leisure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a benchmark of luxury and elegance for the later yachts in the area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of large yachts was originally heavily affected by the success of America, which was drawn 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 victory at Cowes in 1851. Earlier yachts were not designed and built in a contemporary sense, with only a model for an outline. Not until the later half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the use of the study of aerodynamics do for the craft of sails and rigging what it had already done for hulls.

Because almost all sailboats were individually manufactured, there arose a desire for handicapping boats before the one-design class boats were designed. Hence, a rating rule was decreed, which ended up in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the most rapidly growing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to single specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing such boats can be done on an even keel with no handicapping at all. A great example is the standard International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

As long as yachting was an activity primarily for the royal and the wealthy, money was no problem, and the size of boats developed, in both length and weight. The rise and popularity of smaller boats happened in the latter half of the 19th century from 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) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Later in the 20th century, notably after World War II, smaller racing and pleasure boats became commonplace, down to the dinghy, a preferred 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
Post the decade 1840–50, during which steam began to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure craft. Bigger power yachts were progressed to a high degree, and long-distance travel turned into a fond occupation of the wealthy. The earliest power yachts were paddle-wheel boats; they then gave rise to boats powered by the wholly submerged screw or propeller sort of propulsion. As in the case of naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for many years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a push in the manufacture of more sizeable steam yachts. In particular of 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 gave active service during World War II.

As larger and more dependable internal-combustion engines were created, many bigger boats started using them for power. The development of the diesel engine, employing heavy oil for fuel, progressed for World War I. In the decade following, large power-yacht manufacture flourished, climaxing 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 manufacture of large power craft declined after 1932, and the style after that was in preference of smaller, less costly craft. Following World War II, a lot of small naval craft were bought by private owners for conversion to yachts. In the late 20th century, yachting had become a globally beloved sport enjoyed by thousands of yachtsmen individually sailing and upkeeping their own small leisure yachts. The popularity of yachts and sailors increased steadily, not only in the traditional places on the seacoasts but also on inland waterways and lakes.

Taxes can be differentiated by the effect they have on the distribution of income and wealth. A proportional tax is a tax that puts the same relative liability on each taxpayer—i.e., where tax liability and income move in relative scale. A progressive tax is characterizable by a greater than proportional rise in the tax burden in relation to the increase in income, and a regressive tax is characterizable by a less than proportional increase in the related liability. Hence, progressive taxes are thought of as fighting inequalities in income distribution, whereas regressive taxes are seen to have the effect of increasing these inequalities.

The taxes that are generally thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so within the upper-income group—especially if a taxpayer is able to reduce his tax base by claiming deductions or by taking particular income components 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 period does not necessarily come up with the most appropriate measure of taxpaying requirement. For example, transitory rises in income might be saved, and in temporary declines in income a taxpayer might select to finance consumption by reducing savings. Thus, if taxation is compared along with “permanent income,” it can be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (except luxuries) tend to be regressive, because the share of one’s income consumed or spent for a specific good declines as the amount of personal income increases. Poll taxes (aka head taxes), nominated as a set amount per capita, patently are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden rests for the most part on whether a national or a subnational (that is, provincial or state) tax is being decided.

In assessing the economic purpose of taxation, it is necessary to distinguish between several concepts of tax rates. The statutory rates include those nominated in legislation; generally these are marginal rates, but for some cases they are median rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income rises by one dollar. Therefore, if tax liability rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that increase as income grows. Careful analysis of marginal tax rates should regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified within the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applicable to income from business and capital, as it may depend on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates determine the percentage of total income that is taken in taxation. The pattern of average rates is the one that is important for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally grow with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households could dampen these effects, allowing regressivity, as signified by average tax rates that decline as income rises.

The LCDs utilised for projection systems are typically small reflective or transmissive panels illuminated by a powerful arc lamp source. A series of lenses expands the reflected or transmitted image then displays it onto the screen. For front-projection systems the LCD is set on the same area of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of higher expense and capability sometimes utilise three distinct LCD panels, creating separate red, green, and blue images that blend to make a coloured display on the screen.

The growth in need for pictographic presentations has placed a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices using smectic liquid crystals, some of which have a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. In it the liquid crystal molecules are set out in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as demonstrated in the figure. The host liquid crystal possesses optically active molecules, and a subtle turn up of the optical activity and the angle 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 through the plane of the layers. Thus, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been commercialized for bigger passive-matrix displays, but their high cost and complexity has hindered them from having any particular effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reacting allows them to be utilised in time-sequential colour systems, in which highly expensive colour filters are replaced with a coloured backlight that flashes red, green, and blue in fast pulsing (around 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state during the red and green periods and 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 each of the furniture needs, the chair may be the primary one. While the majority of other forms (save for the bed) are designed to support objects, the chair supports your human form. The term chair is viewed here in the larger sense, from stool to throne to further kinds like the bench or sofa, which may be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinuishable.

The social history of the chair is as interesting as its history as a creative craft. The chair is not just a physical support and/or an aesthetic craft; it historically was semiotic of social rank. From the past royal courts there were significant differences between having a chair with arms, or a chair with a back but no arms, or worse having to sit on a stool. In the past century, the director’s and/or manager’s chair has been regarded as an identifier of superior position, and in democratic government debate the speaker sits on an elevated platform.

As its furniture construction, the chair can be employed for a wealth of various forms. There are chairs created to suit man’s age and physical condition (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). During the olden days there were chairs for births (birth chairs); from the 20th century, there have been chairs to die in (the electric chair). We have chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated particular chairs for automobiles and aircraft. All these chair kinds has been perfected to match to differing human desires. From its particular importance with man, the chair lives to its full advantage only when utilised. Whereas it doesn’t make a difference to one’s appreciation of a cupboard or a chest of drawers if there are things inside or not, a chair is really understood and judged best with a person using it, because chair and sitter need one another. Thus the different limbs of the chair are given labels like the limbs of the human shape: arms, legs, feet, back, and seat.

Because the simple purpose of your chair is to support your body, its credit is judged primarily on how well it measures up to this practical use. Within the design of a chair, the builder is bound by particular static rules and principal measurements. Within these rules, however, the chair creator has large freedom.

The history of the chair is an epoch of several thousand years. There were societies that held significant chair shapes, as expressions of the highest endeavour in the arenas of technique and art. Among these such cultures, special note should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of careful make, are now known from findings made in tombs. The first one of the two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs structured as akin to those of a designated animal, a curved seat, leading to a sloping back supported from vertical stretchers. In this way a durable triangular construction was obtained. There was from our view no particular differentiation from the creation of Egyptian thrones and chairs for ordinary peasantry. The simple variation lies in the kind of ornamentation, in the choice of expensive inlays. The Egyptian folding stool in all likelihood was created as an easily packed seat for army soldiers. As a camp stool that chair continued til much later days. But the stool then was designed for the role of a ceremonial seat, its technical job as a folding stool ignored or forgotten. This can from today’s evidence be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are constructed in the form of folding stools but cannot be folded as the seats were made from wood. The plain construction of the folding stool, made of two frames that spin on metal bolts and hold a seat of leather or fabric secured between them, reappears somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of these is the folding stool, made of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not with any ancient specimen still around but seen in a large amount of pictorial items. The most recognisable is the klismos placed on the Hegeso Stele at the Dipylon burial location by Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of those could be visible. These unusual legs were most likely crafted of bent wood and were likely to have been had huge pressure under the weight of the sitter. The joints securing the legs to the frame of the seat are therefore very solid and were visibly signified.

The Romans emulated the Greek designs; quite a few models of seated Romans show evidence of a thicker and in appearance rather less delicately designed klismos. Both styles, light and heavy, were brought back in the Classicist period. The klismos style is found in French Empire styles, in English Regency, and in some brands of marked originality in Denmark and Sweden around 1800.

China
The progression of the chair in China is not able to be tracked as far as the progression of the chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed collection of images and artworks was kept safe, displaying the insides and outer parts of Chinese households and their furniture. Also kept of the 16th century are some chairs crafted from wood or lacquered wood, that hold an amazing resemblance to representations of ancient chairs.

Just the same as in Egypt, there existed two particular chair forms in China: a chair of four legs and a folding stool. This four-legged chair is found both with and without arms though never missing its square seat and straight stiles (standing side supports) to support the back. In one type, though, the stiles are slightly curved on top of the arms to fit the form of the S-shaped back splat (the main upright of the back). Together, all three areas were mortised onto the yoke-like top rail. While the innovation of a back splat had an introduction for English chairs during the Queen Anne period, wooden pieces that only to a limited extent reinforce corner joints (and were loose in the result) signify a feature particular to Chinese chairs. The four legs are set through the seat frame, which ends over the rounded staves. Members are round in section or has rounded edges—references maybe to the bamboo tradition. The seat is not comfortable and may have had a plaited texture. These chairs needed the sitter to hold themselves stiff and upright; if too much weight is exerted on the back, the chair has a tendency to fall. In patriarchal Chinese households of this period armchairs presumably were allowed 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 that much from the Egyptian and Scandinavian folding stools, but it has a variation in that the top rail is delicately held to the two legs of the stool by use of a curved member, which is generally provided with metal mounts. From a Western point of view the ultimate effect of both of these furniture items is stylized. The constructive and decorative parts are combined in a style that is both naïve and refined. The piecemeal appearance is an outcome of the way that the individual members do not look to have been adjoined by means of either glue or screws, but were mortised on one another and locked into its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its name on the chair. Works of art project a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to bring out a pattern of small pads. The front board and a related board from the back could be folded after loosening some small iron hooks. In this way the chair was a readily portable piece of furniture in traveling which, at the same time, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is seen 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. While this style of chair can also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not believed that the innovation actually was instigated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slim dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was produced in considerable amounts, as surmisable from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up by a wall. The design asserts itself by virtue of 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 was, as developed in Paris around 1750—spread through most of Europe and was imitated or copied in the mid-20th century. The chair owes this popularity to a combination of leisure and charm. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are tiny upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of relatively thick density; but each member is deeply molded, all superfluous wood has been taken away, and more expensive examples can be further embellished with special delicate and decorative carving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used instead of upholstery.

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

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

Late 18th to 20th century
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 recording of the money values of the operation of a business. Bookkeeping provides the figures from which accounts are made but is a different process, required prior to accounting.

Basically, bookkeeping grants two areas of information: (1) the current value, or equity, of an enterprise and (2) the changes in value—profit or loss—taking place in the entity within a particular period of time.

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

Evidence of financial and numerical records are seen for just about every country with a commercial backbone. Records of trading contracts were found in the archaelogy of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The two-entry method of bookkeeping began with the furthering of the commercial republics of Italy, and tutorials for bookkeeping were produced during the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial bookkeeping a requirement. The history of bookkeeping, in fact, closely resembles the history of commerce, industry, and government and, in some part, assisted to shape it. The international revolution of industrial and commercial activity required better sophisticate decision-making methods, which in turn demanded more sophistication in the selection, classification, and presentation of information, more so with the assistance of computers. Taxation and government legislation became more significant and resulted in increased need for information; 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 demand for bookkeeping for their own inner departmental operations increased.

Though bookkeeping methodology can be rather detailed, all are based on two styles of books used in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger must have the record of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The job of the income statement or profit-and-loss statement is to give an analysis of those changes that have occurred in the entity equity from the events of the period. The balance sheet gives the financial position of the enterprise at the 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 yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

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

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

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

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