The typical question heard when purchasing a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, an acronym 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 models available, it can be overwhelming for clients to pick between both technologies. Ultimately LCD projectors give far superior image quality and colour accuracy. The following article explains why DLP projectors struggle with projecting a comparable rate of image quality.

Think of a set of blinds in your house for your bedroom window. By pulling on a rod you can make the shutters open or closed, depending on whether you want to let light in or not. And this is exactly how an LCD projector functions. Each pixel works like a single 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 experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector is turned on to when the image reaches your screen is vitally significant for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by separating it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by shining each pixel on and off. The pixels are then projected in a glass prism to send the projector image. Something important to realise about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector functions is very different and even the way an image comes out is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image casts a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create 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 complete image. Using LCD projectors, all colours are available all the time to form the highest brightness and superb colour accuracy. In DLP, just one colour is available at a time, resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment in the colour wheel to improve all over brightness, but this also detracts from colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and thus must be superior quality. For those who do not 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 capable of producing. DLP projectors do possess high contrast specifications in comparison to a majority of LCD projectors. At a glance, this can seem to be an advantage, however, in the real world, the true black level is determined by the ambient light in the room when the projector is being used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to view has moving images, DLP projection technology also has image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector displays with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are projected. LCD projectors do not have this characteristic because all the colours are sent at once. DLP developers have formed 3DLP solutions using 3 chips to solve the colour break up error, but the cost of these projectors make them almost impossible for the majority of businesses and consumers.

Another point of difference between LCD and DLP is how they balance for the refractive qualities of light. Think back to high school science, and they taught you how the different colours of light refract differing amounts when passing through the same lens. The disadvantage with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Often with a DLP projector, a spill of yellow colour will appear above and a spill of blue will come through below something as simple as a lone black line. While being built LCD projectors can be set to minimize these effects on the projected image, as each colour is directed on isolated LCD panels.

The sole real buy point (excluding price) with going with a DLP projector is its smaller total size and weight. However, this is only relevant for mobility and cannot be traded off against the image benefits of LCD projectors. If the outcome of the picture quality is vital to you, then the decision is easy. Go with an LCD projector! LCD projectors will always create bright, colourful images with fewer image blips.

As the Dutch rose to dominance in sea power during the 17th century, the first yacht was a leisure craft used first by royalty and secondly by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam gave him 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, sovereign 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting was found to be popular among the affluent and royalty, but after that period the fashion did not last.

The first yacht group in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had much naval panoply and formality. The closest thing to racing boats 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 known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated method on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it was then called 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 initiated 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 continuing site of British racing. The association at Cowes became the Royal Yachting Club, likewise at the rise of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for large bids were held, and the social life was lovely. Eventually Royal Yachting Club boats grew 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 for the most part for leisure and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The craft of sizeable yachts was originally heavily impacted by the success of America, which was designed by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. Early yachts were not designed and built in a contemporary sense, with just a model used. Not until the later half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the application of the science of aerodynamics do for the craft of sails and rigging what such science had already done for hulls.

Because almost all sailboats had been individually built, there came a need for handicapping boats previous to the one-design class boats were designed. Therefore, a rating rule was decreed, which ended up in the International Rule, adopted in 1906 and amended in 1919. Today, one of the most rapidly blossoming areas in sailing 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 elements (for an example of a two-person sailboat, see illustration). Racing these boats can be held on an even playing field with no handicapping at all. A perfect example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

So long as yachting was an activity largely for the aristocracy and the affluent, cost was no object, and the size of boats developed, in both length and weight. The ascendancy and preference of smaller yachts happened in the later 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 voyage around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of smaller boats. Later in the 20th century, particularly after World War II, smaller racing and recreational yachts became more popular, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam was set to replace sail power in market craft, the steam engine, and later the internal-combustion engine, were favoured increasingly in pleasure yachts. Sizeable power yachts were progressed to a high standard, and long-distance travel turned into a preferred activity of the well off. The earliest power yachts were paddle-wheel boats; they then made way to yachts powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were only power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the construction of large 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 more than 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service for World War II.

As bigger and more reliable internal-combustion engines were developed, many bigger craft were using them for power. The development of the diesel engine, using heavy oil for fuel, progressed during World War I. In the decade that followed, large power-yacht manufacture flourished, climaxing in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of large power boats fell away after 1932, and the trend thereafter was in preference of smaller, less pricey boats. From World War II, many small naval boats were traded by private owners for conversion to yachts. By the late 20th century, yachting is a widespread loved activity enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small recreational craft. The popularity of craft and yachtsmen is increasing steadily, not only in the traditional places on the beach but also on inland waterways and lakes.

Taxes can be distinguished by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that impinges the same relative onus on each taxpayer—i.e., where tax liability and income increase in equal scale. A progressive tax is recognised by a more than proportional growth in the tax onus in regard to the growth in income, and a regressive tax is recognised by a less than proportional growth in the relative onus. Therefore, progressive taxes are viewed as reducing inequity in income distribution, but regressive taxes might result in increasing these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, can become less so within the upper-income categories—particularly if a taxpayer is permitted to lessen his tax base by nominating deductions or by excluding some income elements from his taxable income. Proportional tax rates if applied to lower-income classes will also be more progressive if exemptions of a personal nature are declared.

Income measured over a given year may not necessarily give the most accurate measure of taxpaying ability. For example, transitory rises in income can be saved, and in temporary declines in income a taxpayer might opt to pay for consumption by taking from savings. Ergo, if taxation is made comparable alongside “permanent income,” it would be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (with the exception of luxuries) are generally regressive, because the dissemination of personal income consumed or spent for a specific good lessens as the amount of personal income grows. Poll taxes (also known as head taxes), nominated as a set amount per capita, patently are regressive.

It is hard to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty around 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 determined.

In assessing the economic effect of taxation, it is relevant to distinguish between differing ideas of tax rates. The statutory rates are those nominated in legislature; commonly these are marginal rates, but sometimes they are average rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income is increased by one dollar. Thus, if tax burden rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws usually contain graduated marginal rates—i.e., rates that grow as income increases. Structured analysis of marginal tax rates must take into account provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than nominated within the statutory rates. Since marginal rates signify how after-tax income moves 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 know the marginal effective tax rate applied to income from business and capital, because it may be reliant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates determine the part of total income that is taken in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates generally rise with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households can dampen these effects, producing regressivity, as shown by average tax rates that lessen as income increases.

The LCDs utilised in projection systems are most often small reflective or transmissive panels set off by a strong arc lamp source. A line of lenses enlarges the reflected or transmitted image and casts it onto a screen. For front-projection systems the LCD is situated on the same area of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of higher cost and performance sometimes have three separate LCD panels, reflecting separate red, green, and blue images that mesh to make a coloured display on the screen.

The increase in need for pictographic displays has placed a special emphasis on the switching speed of liquid crystals. This has necessitated the invention of devices utilizing smectic liquid crystals, some of which possess a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. With it the liquid crystal molecules are cast in perpendicular layers to the substrate planes, which are separated by one or two micrometres, and within the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible outcome of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous 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. Therefore, there is a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered 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 by doing so reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been publicized for large passive-matrix displays, but their expense and intricacy has hindered them from having any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be used in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid pulsing (around 100 cycles a second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods but to a nontransmissive state during the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

Out of each of the furniture forms, the chair might be the most imperative. While the majority of other items (except the bed) are devised to support objects, the chair supports our human form. The term chair can be said here in the most general sense, from stool to throne to developed kinds including the bench or sofa, which should be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly labeled.

The social history of the chair is as stimulating as its history as art and craft. The chair is not just a physical support and/or an aesthetic item; it was historically a symbol of social standing. From the Medieval royal courts there were significant differences between possessing a chair with arms, on a chair with a back but no arms, or worse having to use a stool. From the past century, a director’s and/or manager’s chair has become an identifier of superior status, and even in democratic parliaments the speaker sits on a raised level.

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

Contemporary lifestyle has derived new chairs for automobiles and aircraft. All of these chair forms has been evolved to fit to growing human needs. Due to its unique link with man, the chair lives to its full advantage only when in use. Although it is irrelevant to one’s appreciation of a cupboard or a chest of drawers if there are things inside or not, a chair is best seen and fairly evaluated by a person utilising it, because chair and sitter suit one another. Thus the different limbs of the chair have been given labels corresponding to the limbs of our human body: arms, legs, feet, back, and seat.

Because the clear work of the chair is to support our human body, its worth is tested generally from how fully it does fulfill this practical function. Within the design of the chair, the carpenter is restricted by the static regulations and principal measurements. Under these limitations, however, the chair builder has great freedom.

The history of the chair is a period of several thousand years. There existed societies that created significant chair forms, as seen of the topmost craft in the arenas of skill and design. Out of these civilisations, a mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of skilled craft, are now found from tomb discoveries. One of them is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair has four legs designed not unlike those of a particular animal, a curved seat, and with a sloping back supported above vertical stretchers. In this way a solid triangular design was obtained. There was to our knowledge no marked difference in the structure of Egyptian thrones and chairs for ordinary citizens. The general variation lied in the intricacy of its ornamentation, in the choice of more expensive inlays. The Egyptian folding stool probably was developed as an easily carried seat for soldiers. As a camp stool this chair existed for much later periods. But the stool also then was created for the role of a ceremonial seat, its mechanical task as a folding stool being forgotten. This can from today’s evidence be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are in the construction of folding stools but can’t be folded as the seats are created out of wood. The easy structure of the folding stool, composed of two frames that turn on metal bolts and hold a seat of leather or fabric held between them, can be seen somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this form is the folding stool, made out of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is recognised not in any ancient item still around but in a large amount of pictorial material. The significant kind is the klismos depicted on the Hegeso Stele at the Dipylon burial location just out of Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them would be seen. These creative legs were thought to have been executed of bent wood and were therefore put under huge pressure under the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore very stable and were overtly denoted.

The Romans embued the Greek design; existing statues of seated Romans offer designs of a more heavyset and which appear to be a kind of less intricately built klismos. Both kinds, the light or the heavy, were brought back as part of the Classicist era. The klismos influence can be seen in French Empire styles, in English Regency, and in some forms of notable uniqueness in Denmark and Sweden during 1800.

China
The ancestry of the chair in China isn’t able to be charted as well as the history of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) a full collection of images and artworks was kept, with images of the inside and outside of Chinese buildings and the kinds of furniture. Kept also from the 16th century are some chairs made from wood or lacquered wood, that possess an astonishing likeness to pictures of ancient chairs.

Just like in Egypt, there was two major chair designs in China: a chair of four legs and a folding stool. The four-legged chair was seen both with and without arms but never without the square seat and straight stiles (vertical side supports) to give support to the back. In one style, it has been seen, the stiles are delicately curved over the arms to suit the form of the S-shaped back splat (the central upright of its chairback). Together, the three limbs were mortised on the yoke-like top rail. While the innovation of a back splat later had an inspiration for English chairs of the Queen Anne period, wooden members that would merely to a limited capability embolden corner joints (and then were loose into the bargain) signify a feature solely to Chinese chairs. The four legs pass through the seat frame, which ends around the rounded staves. All the members are round in section or is given rounded edges—an acknowledgement maybe to the bamboo tradition. The seat is uncomfortable and may have had a plaited texture. These chairs required of the sitter to be stiff and upright; when too much pressure is pushed on the back, the chair has a habit of collapsing. In patriarchal Chinese houses of this period armchairs most likely were kept only for elderly people in the family, for they were esteemed greatly.

The Chinese folding stool is understood to have travelled to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it has a difference in that the top rail is prettily joined to the two legs of the stool by use of a curved member, which is generally possessing metal mounts. From a Western viewpoint the ultimate effect of both these furniture styles is stylized. The manufacture and decoration elements are combined in a style that is simultaneously naïve and refined. The pieced-together appearance is an outcome of the way that the individual members do not appear to have been held together by means of either glue or screws, but were mortised into one another and locked into position in the manner of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered style of chair can be displayed in engravings of the inside 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 kind of chair is also made in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not certain that the design actually originated in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of slender shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was made in considerable amounts, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of those chairs lined up against a wall. The form asserts itself with its shapely 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 forms—that is, as developed in Paris around 1750—spread through most of Europe and was imitated or copied into the mid-20th century. The chair owes such popularity to a combination of leisure and elegance. The seat suits to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed strongly on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of relatively thick dimensions; but all members are deeply molded, all extra wood has been removed, and finer items may be further embellished with special delicate and decorative carving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all of the upholstery on the seat, back, and armrests; canework is sometimes used as an alternative to upholstery.

English chairs in the 18th century were more differentiated in style than the French. The French taste for stylistic uniformity, which disseminated from the aristocratic circles in Paris and Versailles throughout most of France and was popular 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 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 products 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, suggest that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping grants the information from which accounts are drafted but is a distinct process, preliminary to accounting.

Fundamentally, bookkeeping records two types of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking place in the business from a given time.

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

Pieces of financial and numerical record charts have been uncovered for nearly every state with a commercial background. Records of trade contracts have been found in the ruins of Babylon, and accounts for both farms and estates have been created in ancient Greece and Rome. The dual-entry way of bookkeeping came up with the furthering of the business republics of Italy, and manuals for bookkeeping were developed in the 15th century in several Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial books a paramount factor. The ancestry of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, partially, helped to shape it. The global revolution of industrial and commercial activity called for greater cosmopolitan decision-making processes, which in turn demanded greater sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislature became more significant and resulted in increased demand for information; enterprises 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, and the requirement for bookkeeping for their own inner departmental operations became larger.

Though bookkeeping methodology can be rather multifaceted, all are based on two types of books employed in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and such), and the ledger contains the record of individual accounts. The daily records in the journals are put in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are created from the trial balance posted from the ledger. The job of the income statement or profit-and-loss statement is to provide an analysis of any changes that occurred in the business equity resulting due to the transactions of the period. The balance sheet provides the financial condition of the business at the particular date in terms of assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

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