The most typical question customers ask when looking for a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many company brands and different models available, it can be confusing for customers to make a choice between these technologies. The fact is that LCD projectors have far superior image quality and colour accuracy. The following article explains why DLP projectors struggle with bringing up an equal level of image quality.

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

How the light source is processed from the point when the projector is switched on to when the image reaches your screen is extremely significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting 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 cast the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. An important point to realise about LCD projectors is that all three colours are directed onto your projected surface at the same time. The way a DLP projector functions is vastly different and even the way an image appears is not the same. With DLP, white light from the lamp is projected through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming 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 construct the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into a full image. Using LCD projectors, all colours are available all the time to offer the highest brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP designers have placed a white segment in the colour wheel to improve brightness generally, but this goes and degrades colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and as such must be better quality. 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. DLP projectors do provide high contrast specifications in comparison to a majority of LCD projectors. At one glance, this must be a benefit, however, in reality, the true black level is determined by the ambient light in the room where the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you wish to project includes moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are shone. LCD projectors do not have this downside because every colour is delivered simultaneously. DLP designers have developed 3DLP solutions using 3 chips to fix the colour break up artifacts, but the expense of these projectors make them not practical for many businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and they taught you how the different colours of light refract varied amounts when passing through the same lens. The downfall with DLP projectors is that they have the one same panel for the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Generally with a DLP projector, some extra yellow colour will appear above and an extra blue will appear below an image of something as simple as a straight black line. While being built LCD projectors can be adapted to reduce these effects on the projected image, because each colour is refracted on its own LCD panels.

The one true benefit (excluding price) with taking a DLP projector is its smaller total size and weight. However, this is only relevant for portability and cannot be traded off against the image advantages 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 constantly make 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 leisure craft used first by royalty and then by the burghers for the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his restoration 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 then 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 back, on a £100 punt. Yachting was found to be popular with the wealthy and royalty, but after that period the fashion did not last.

The first yacht club in the British Isles, the Water Club, was started around about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held much naval panoply and gravity. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imaginary enemy. The club endured, largely as a social club, until 1765, and in 1828, when joining with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated method on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it was 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 club had been started 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 continued site of British yacht racing. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing races for great bids were held, and the social life was lovely. Ultimately Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English held power. Sailing was mostly for pleasure and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a benchmark of luxury and elegance for the later yachts in those waters from the late 19th century. The first continuing American yacht society, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The design of bigger yachts was first largely impacted by the win 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.) was named after its victory at Cowes in 1851. Early yachts were not designed and manufactured in a contemporary sense, with merely a model for an outline. Not until the later half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the use of the study of aerodynamics do for the craft of sails and rigging what such science had previously done for hulls.

Because almost all sailboats had been individually custom-built, there was a requirement for handicapping boats before the one-design class boats were built. Thus, a rating rule was decreed, which is found in the International Rule, taken on in 1906 and amended in 1919. In modern times, one of the fastest blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between those boats can be had on an even keel with no handicapping at all. A great example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

As long as yachting was an activity largely for the aristocracy and the wealthy, cost was no object, and the size of boats grew, in both length and weight. The promotion and desire of smaller boats occurred in the latter half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of less sizeable yachts. Thereafter in the 20th century, notably after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a preferred 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
Post the decade 1840–50, in which steam was set to take the place of sail power in public vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure vessels. Sizeable power yachts were furthered to a high element, and long-distance cruising turned into a preferred pastime of the affluent. The early power yachts were paddle-wheel boats; these then made way to yachts powered by the wholly submerged screw or propeller sort of propulsion. As in the case of naval and merchant vessels, auxiliaries possessing both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the large part were exclusively power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the construction of more sizeable steam yachts. Conspicuous among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of 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 large craft started using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced during World War I. From the decade that followed, bigger power-yacht manufacture grew, climaxing in the Orion (1930) at 3,097 tons. In that period the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of big power yachts lessened after 1932, and the fashion thereafter was for smaller, less expensive boats. Following World War II, a lot of small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a widespread beloved sport enjoyed by thousands of yachtsmen personally owning and keeping their own small leisure craft. The number of boats and owners has increased steadily, not only in the traditional locations along the sea but also on inland waterways and lakes.

Taxes are differentiated by the impact they have on the distribution of income and wealth. A proportional tax is one that applies the same relative onus on every taxpayer—i.e., when tax liability and income grow in relative scale. A progressive tax is recognised by a more than proportional rise in the tax liability relative to the growth in income, and a regressive tax is characterized by a less than proportional growth in the comparative liability. Therefore, progressive taxes are seen as removing inequalities in income distribution, whereas regressive taxes are seen to result in an increase these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so in the upper-income categories—in particular if a taxpayer is permitted to lower his tax base by claiming deductions or by leaving out some particular income components from his taxable income. Proportional tax rates if applied to lower-income categories can also be more progressive if such exemptions of a personal nature are declared.

Income measured over the period of a year does not necessarily provide the most accurate measure of taxpaying status. For example, transitory growth in income might be saved, and during temporary declines in income a taxpayer could choose to provide for consumption by reducing savings. Ergo, if taxation is made comparable alongside “permanent income,” it can be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (save on luxuries) are generally regressive, because the portion of one’s income consumed or spent for specific goods lessens as the level of personal income grows. Poll taxes (also called head taxes), calculated as a standard amount per capita, obviously are regressive.

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

In considering the economic effects of taxation, it is necessary to distinguish between differing concepts of tax rates. The statutory rates are nominated in the law; generally these are marginal rates, but sometimes they are median rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income increases by one dollar. Thus, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws generally contain graduated marginal rates—i.e., rates that increase as income rises. Structured analysis of marginal tax rates are required to review 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 growth in income, the marginal rate is 20 percentage points more than specified in the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for assessing incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applicable to income from business and capital, as it may be reliant on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the part of total income that is taken in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates generally increase with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; on the other side of things, preferential treatment of income received for the most part by high-income households can dwarf these effects, forcing regressivity, as shown by average tax rates that lower as income rises.

The LCDs used in projection systems are generally small reflective or transmissive panels illuminated by a bright arc lamp source. A number of lenses magnifies the reflected or transmitted image and displays it onto a screen. With 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 illuminated from behind. Projectors of greater cost and performance may use three separate LCD panels, forming separate red, green, and blue images that blend to reflect a coloured image on the screen.

The growing desire for pictographic presentations has placed a particular emphasis on the switching speed of liquid crystals. This has necessitated the invention of items employing smectic liquid crystals, particular 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 progressive smectic device. With it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and in the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal has optically active molecules, and a subtle outcome of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. So, there has to be a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been marketed for larger passive-matrix presentations, but their cost and complex nature has hindered them from enjoying any significant effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some promise for use as elements in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be employed in time-sequential colour systems, in which dear colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid speed (around 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but to a nontransmissive state during the blue period, creating the result that the eye sees an average of red and green light, or the colour yellow.

Out of all furniture objects, the chair could be the primary one. While most of the other pieces (save the bed) are intended to support objects, the chair supports your human form. The term chair is intended to be looked upon here in the most open sense, from stool to throne to further forms for example a bench and sofa, which may be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinuishable.

The social history of the chair is as exciting as its history as an art and craft. The chair is not only a physical support and/or aesthetic piece of art; it historically is an indicator of social place. At the Medieval royal courts there were significant signifiers between sitting on a chair with arms, or a chair with a back but without arms, or worse having to cope with a stool. During the recent century, the director’s and manager’s chair has been regarded as an indicator of superior status, as well as in democratic government debate the speaker sits on an elevated floor.

As its furniture form, the chair ranges from a range of variations. There are chairs manufactured to attend to man’s age and physical condition (the high chair, the wheelchair) and to show his status in society (the executive chair, the throne). During the olden days there were chairs to be born in (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). We design chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our lifestyle has demanded particular chairs for use in automobiles and aircraft. All of these chair kinds have adapted to conform to differing human requirements. For its particular link with man, the chair comes to its full meaning only when in use. Though it makes no difference to one’s appreciation of a cupboard or a set of drawers whether there might be things inside or not, a chair is understood and fairly judged with a person sitting on it, for chair and sitter suit one another. Thus the different limbs of a chair were named according to the areas of our human shape: arms, legs, feet, back, and seat.

Because the obvious job of your chair is to support a human body, its worth is evaluated primarily on how completely it does measure up to this practical purpose. In the build of the chair, the builder is bound under some static legislation and principal measurements. Under these rules, however, the chair designer has extensive freedom.

The history of the chair extends over a period of several thousand years. There were civilizations that made unique chair shapes, expressive of the topmost object in the arenas of handling and creativity. From these such societies, special note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of careful make, are today known from tomb discoveries. The first of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have four legs formed like those of some animal, a curved seat, and with a sloping back supported from vertical stretchers. In this way a strong triangular design was obtained. There was from our view no particular difference in the design of Egyptian thrones and chairs for common peasantry. The general variation was in the complex ornamentation, in the selection of expensive inlays. The Egyptian folding stool probably was created as an easily packed seat for soldiers. As a camp stool the stool continued during much later days. But the stool also took on the purpose of a ceremonial seat, its original job as a folding stool fast forgotten. This can already be found, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are constructed in the form of folding stools but are not able to be folded because the seats are formed with wood. The plain construction of the folding stool, consisting of two frames that spin on metal bolts and have a seat of leather or fabric held between them, then came up but some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this type is the folding stool, made out of ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not from any ancient specimen still existing but as in a large amount of pictorial objects. The best recognised is the klismos seen on the Hegeso Stele at the Dipylon burial place near Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them can be shown. These unusual legs were likely to have been crafted with bent wood and were likely to have been had to bear great pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat are therefore extremely solid and were plainly pointed out.

The Romans embued the Greek style; evidence of statues of seated Romans show chairs of a heavier and apparently somewhat crudely designed klismos. Both styles, the light and heavy, were popularised in the Classicist time. The klismos chair is found in French Empire design, in English Regency, and in some particular brands of notable uniqueness within Denmark and Sweden during 1800.

China
The past of the chair in China is not able to be traced as well as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed series of sketches and paintings was kept, displaying the interior and exteriors of Chinese homes and the kinds of furniture. Another preservation from the 16th century are a trove of chairs of wood or lacquered wood, that display an intriguing likeness to images of previous chairs.

Like in Egypt, there were two iconic chair forms in China: a chair of four legs and a folding stool. That four-legged chair is constructed both with or without arms however never missing the square seat and straight stiles (upright side supports) to support the back. In one form, it has been seen, the stiles could be marginally curved on top of the arms for the purpose of conform correctly to the form of the S-shaped back splat (the central upright of the back). Together, the three parts are mortised into the yoke-like top rail. Though the idea of this back splat then had a foundation for English chairs of the Queen Anne period, wooden sections that merely to a limited capability support corner joints (and furthermore are loose to top that off) are an element exclusive to Chinese chairs. The four legs are set through the seat frame, which closes about the rounded staves. All members are round in section or possesses rounded edges—acknowledging maybe to the bamboo tradition. The seat is not pleasant and occasionally had a plaited texture. These chairs needed the sitter to remain stiff and upright; for when too much pressure is forced on the back, the chair has a habit of collapsing. In patriarchal Chinese homes of this period armchairs likely were allowed only for senior family members, for they were given great respect.

The Chinese folding stool is believed to have been brought to China from the West. It does not differ that much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is delicately joined to the two legs of the stool by use of a curved member, which is generally seen with metal mounts. From a Western perspective the overall effect of both these furniture designs is stylized. The constructive and aesthetic elements are combined in a manner that is all at once naïve and refined. The pieced-together appearance is an upshot of the manner that the individual members do not appear to have been affixed by either glue or screws, but are mortised onto one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its mark on the chair. Works of art show a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in the layers, stitched to show up a pattern of little pads. The front board and a related board from the back could be folded after loosening some little iron hooks. In this way the chair was a portable piece of furniture for traveling which, at the same time, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be seen in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair can also be seen in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the design actually was instigated in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of thin dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in impressive amounts, as surmisable from one of Abraham Bosse’s engravings, in which an entire row of such chairs lined up by a wall. The style asserts itself with its shapely 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 forms—that is, as created in Paris around 1750—spread through most of Europe and was imitated or copied during the mid-20th century. The model owes the popularity to a combination of relaxation and charm. The seat suits 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 small upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back conceal all the joints, which are constructed solidly on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of relatively thick dimensions; but every member is deeply molded, all extra wood has been sanded away, and more upmarket chairs would be further embellished with highly delicate and decorative engravings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for any upholstery on the seat, back, and armrests; cane is in some cases used in place of upholstery.

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

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became well-known 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 versions of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, indicate that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping gives the numbers from which accounts are written but is a previous process, prior to accounting.

Fundamentally, bookkeeping provides two areas of information: (1) the current value, or equity, of the entity and (2) any changes in value—profit or loss—taking placement in the enterprise during a single period.

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

Evidence of financial and numerical recordkeeping can be seen for almost every state with a commercial history. Records of trade contracts were found in the archaelogy of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The dual-entry way of bookkeeping came with the progression of the entrepeneurial republics of Italy, and tutorial books for bookkeeping were created during the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a paramount factor. The ancestry of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, in part, assisted in shaping it. The worldwide movement of industrial and commercial activity required better professional decision-making methodology, which in turn needed higher sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government legislation became more important and resulted in greater requirement for information; enterprising firms had to have information available to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the need for bookkeeping for departmental operations went up.

While bookkeeping methodology can be very detailed, all of it is based on two types of books employed in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger has the records of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to display an analysis of the changes that have occurred in the ownership equity as a result of the transactions of the period. The balance sheet displays the financial situation of the corporation at any particular point in time derived from assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

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

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

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