The most common question customers ask when buying a new projector for the home, office, or classroom is: would I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and models available, it can be challenging for customers to decide between both technologies. It comes down to the fact that LCD projectors provide far superior image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with reproducing the same standard of image quality.

Visualise a set of blinds in your house over your bedroom window. By pulling a rod you can make the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel functions like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from when the projector is turned on to when the image reaches your screen is vitally significant in regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by dividing it into red, blue and green components, by three mirrors which project the coloured light to 3 separate LCD panels. The 3 LCD panels form the elements of the image by shining each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. An important point to realise about LCD projectors is that all three colours are directed onto your screen simultaneously. The way a DLP projector operates is vastly different and even the produced image looks is not the same. With DLP, white light from the lamp is projected through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to 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 eyes will then draw each coloured element of the image into the single whole image. From LCD projectors, all colours are available all the time to offer top brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some developers have added a white segment into the colour wheel to improve brightness overall, but this further damages colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and thus must be superior. For those who are uncertain, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of producing. DLP projectors do provide high contrast specifications as compared to the majority of LCD projectors. At first glance, this must be a benefit, however, in real life, 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 see has moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is to be expected 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 all colours are delivered at once. DLP designers have come up with 3DLP solutions using 3 chips to resolve the colour break up error, but the cost of these projectors make them not practical for many businesses and consumers.

Another variance between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and recall how various colours of light refract differing amounts when passing through the same lens. The problem with DLP projectors is that they utilise the one same panel and the same lens to project Red, Blue and Green. All 3 colours are different and refract light differently. Usually with a DLP projector, some yellow colour will come through above and an extra blue will come up below an image containing something as simple as a lone black line. While being built LCD projectors can be set to take away these effects on the projected image, because each colour is processed on its own LCD panels.

The only actual plus (excluding price) with taking a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to mobility and cannot be traded off against the image advantages of LCD projectors. If the result of the picture quality is important to you, then the decision is a no-brainer. Choose an LCD projector! LCD projectors will always produce bright, colourful images with fewer image errors.

As the Dutch found preeminence in sea power during the 17th century, the early yacht had been a pleasure craft used mostly by royalty and later by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, borne from private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting was found to be fashionable with the wealthy and nobility, but after that point 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 group, and held much naval panoply and rigour. The closest thing to racing was the “chase,” in which the “fleet” pursued a fictional enemy. The club went on, mostly as a social club, until 1765, and in 1828, by merging with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated 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 sovereignty in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht club had been started 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 site of British yacht racing. The organisation at Cowes became the Royal Yachting Club, also at the rise of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for high stakes were held, and the social life was lovely. Ultimately Royal Yachting Club boats grew in size to more than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English had dominance. Sailing was largely for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a standard of luxury and sophistication for the later yachts in those waters from the late 19th century. The first persisting American yacht association, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of large yachts was initially greatly put upon by the win of America, which was designed by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. Early yachts were not designed and crafted in today’s sense, with only a model being used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the application of the science of aerodynamics do for the structure of sails and rigging what science had done earlier for hulls.

Because almost all sailboats had to be individually custom-built, there came a requirement for handicapping boats before the one-design class boats were built. Hence, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and amended in 1919. In the present day, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for such boats can be had on an even basis with no handicapping necessary. A perfect example is the generic International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

For the time that yachting was done primarily for the royal and the wealthy, cost was no problem, and the size of boats developed, in both length and weight. The rise and popularity of smaller boats occurred 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 trip 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 small craft. Later in the 20th century, notably after World War II, smaller racing and recreational 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 setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, during which steam was set to replace sail power in market boats, the steam engine, and later the internal-combustion engine, were favoured increasingly in pleasure craft. Bigger power yachts were furthered to a high standard, and long-distance cruising became a favourite activity of the rich. The early power yachts were paddle-wheel boats; these then made way to yachts powered by the completely submerged screw or propeller kind of propulsion. Like naval and merchant boats, auxiliaries with both sail and power were the yacht archetype for many years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the manufacture 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 manned by a crew of at least 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 more sizeable and more dependable internal-combustion engines were developed, many big yachts were using them for power. The creation of the diesel engine, with heavy oil for fuel, progressed for World War I. From the decade after, bigger power-yacht building blossomed, hitting a climax in the Orion (1930) at 3,097 tons. From that period the best auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats fell away after 1932, and the fashion after that was in preference of smaller, less expensive craft. After World War II, many small naval boats were bought by private owners for conversion to yachts. In the late 20th century, yachting had become a internationally popular sport enjoyed by thousands of yachtsmen individually manning and upkeeping their own small recreational craft. The popularity of craft and sailors is increasing steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Taxes can be categorized by the impact they have on the allocation of income and wealth. A proportional tax is one that puts the same relative liability on all the taxpayers—i.e., where tax liability and income increase in equal proportion. A progressive tax is characterizable by a larger than proportional increase in the tax liability in relation to the rise in income, and a regressive tax is characterizable by a less than proportional increase in the comparative burden. Therefore, progressive taxes are viewed as taking away the lack of equality in income distribution, while regressive taxes can increase these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, may become less so in the upper-income group—especially if a taxpayer is allowed to lessen his tax base by claiming deductions or by removing some certain income parts from his taxable income. Proportional tax rates if applied to lower-income classes would also be more progressive if personal exemptions are claimed.

Income measured over a given period might not definitely offer the best measure of taxpaying status. For example, transitory rises in income could be saved, and in temporary declines in income a taxpayer could opt to pay for consumption by reducing savings. Thus, if taxation is regarded alongside “permanent income,” it would be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are mostly regressive, because the share of own income consumed or spent for specific goods lessens as the rate of personal income increases. Poll taxes (aka head taxes), calculated 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 due to uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant for the most part on whether a national or a subnational (that is, provincial or state) tax is being determined.

In considering the economic effect of taxation, it is important to differentiate between varied points of tax rates. The statutory rates will include those nominated in legislature; usually these are marginal rates, but occasionally they are median rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income is increased by one dollar. Ergo, if tax liability increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes generally contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates are required to review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than nominated in the statutory rates. Since marginal rates specify how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to know the marginal effective tax rate to apply to income from business and capital, since it may be dependant on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the percentage of total income that is paid 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 grows with income. Average income tax rates generally rise with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households could dwarf these effects, producing regressivity, as indicated by average tax rates that decline as income increases.

The LCDs built for projection systems are usually small reflective or transmissive panels lit up by a strong arc lamp source. A series of lenses enlarges the reflected or transmitted image then displays it on the screen. For front-projection systems the LCD is placed on the same area of the screen as the viewer, however in rear-projection systems the screen is lit from behind. Projectors of more expense and capability may have three separated LCD panels, creating separate red, green, and blue images that come together to reflect a coloured image on the screen.

The growth in demand for film displays has put a growing emphasis on the switching speed of liquid crystals. This has necessitated the creation of devices build with 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 at this point the most progressive smectic device. Within it the liquid crystal molecules are managed in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a subtle turn up of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Thus, there exists a permanent charge separation 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 correct sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The resultant change in optical properties can effect a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been produced for larger passive-matrix displays, but their high cost and complex nature has impeded them from creating any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as parts in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be utilised in time-sequential colour systems, in which high cost colour filters are replaced by a coloured backlight that flashes red, green, and blue in rapid pace (approximately 100 cycles in a second). For example, the liquid crystal can be switched to a transmissive state in the red and green periods but to a nontransmissive state in the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

From each of the furniture objects, the chair might be primary. While many other pieces (save for the bed) are intended to support objects, the chair supports our human form. The term chair was said here in the wider sense, from stool to throne to developed chairs like a bench and sofa, which should be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously defined.

The social history of the chair is as interesting as its history as a creative craft. The chair is not only a physical support or aesthetic object; it historically is a symbol of social standing. Within the old royal courts there were plain differences between sitting on a chair with arms, or a chair with a back but no arms, or having to cope with a stool. In the last century, the director’s and/or manager’s chair has been a symbol of superior position, like in democratic parliaments the speaker sits on a raised level.

In its furniture form, the chair is utilised for a wealth of various makes. There are chairs designed to suit man’s age and physical abilities (the high chair, the wheelchair) and to denote his position in society (the executive chair, the throne). During past times there were chairs for birthing (birth chairs); since 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. We have chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Modern living has demanded particular chairs for automobiles and aircraft. Each and every one of these chair kinds have been perfected to conform to differing human uses. For its unique importance with man, the chair comes to its full purpose only when used. Whereas it makes no difference to one’s appreciation of a cupboard or a chest of drawers if there might be anything inside or not, a chair is understood and evaluated by a person sitting in it, for chair and sitter need each other. Thus the individual areas of a chair are named like the names of the human form: arms, legs, feet, back, and seat.

Because the elementary purpose of a chair is to support the body, its credit is valued primarily from how completely it does fulfill this practical job. In the structure of a chair, the carpenter is restricted with certain static rules and principal measurements. Within these boundaries, however, the chair builder has large freedom.

The history of the chair covered a period of several thousand years. There were civilizations that have created iconic chair shapes, expressive of the leading object in the areas of technique and aesthetics. Out of those peoples, particular mention 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of masterful design, are now known from tomb discoveries. The first of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have had four legs shaped akin to those of a particular animal, a curved seat, leading to a sloping back supported by vertical stretchers. From this a durable triangular construction was made. There was from our knowledge no noteworthy variation between the construction of Egyptian thrones and chairs for typical people. The only variation lies in the intricacy of its ornamentation, in the choice of more valuable inlays. The Egyptian folding stool likely was developed for an easily carried seat for army soldiers. As a camp stool the stool stayed til much later periods. But the stool then was designed as the character of a ceremonial seat, its original function as a folding stool neglected or forgotten. This can from evidence be found, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were in the structure of folding stools but can’t be folded because the seats were formed out of wood. The simple structure of the folding stool, being of two frames that cycle on metal bolts and support a seat of leather or fabric secured between them, came again at some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of those is the folding stool, from ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not from any ancient specimen still around but found in a variety of pictorial material. The better known is the klismos placed on the Hegeso Stele at the Dipylon burial area 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 which can be seen. These unusual legs were most likely to be manufactured with bent wood and were as such had to bear a large amount of pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat were therefore super solid and were overtly signified.

The Romans borrowed from the Greek chair; quite a few casts of seated Romans display examples of a heavier and in appearance rather less delicately designed klismos. Both types, the light and the heavy, were popularised within the Classicist era. The klismos design is found in French Empire styles, in English Regency, and in particular brands of profound individuality in Denmark and Sweden circa 1800.

China
The past of the chair in China cannot be followed as far back as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken collection of images and works of art has been kept, with images of the insides and outside of Chinese houses and the designs of furniture. Kept also of the 16th century are a number of chairs crafted of wood or lacquered wood, that possess an astonishing resemblance to pictures of previous chairs.

Like in Egypt, there were two fundamental chair forms in China: a chair of four legs and a folding stool. This chair can be designed both with and without arms but never missing the square seat and straight stiles (standing side supports) to hold up the back. In one kind, it has been found, the stiles are slightly curved above the arms to sit right with the form of the S-shaped back splat (the basic upright of a back). Together, all three parts were mortised in the yoke-like top rail. Though the innovation of the back splat had a foundation for English chairs during the Queen Anne period, wooden pieces that merely to a limited ability stabilise corner joints (and were loose to top it off) indicate a signature exclusive to Chinese chairs. The four legs sit through the seat frame, which ends over the rounded staves. Each member is round in section or has rounded edges—an acknowledgement maybe to the bamboo tradition. The seat is uncomfortable and may have a plaited bottom. These chairs demanded of the sitter to be stiff and upright; for if too much pressure is pushed on the back, the chair has a tendency to topple. In patriarchal Chinese households of this era armchairs likely were kept only for elderly individuals, for they were greatly respected.

The Chinese folding stool is believed to have travelled to China from the West. It is not dissimilar so very much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is prettily fixed to the two legs of the stool by a curved member, which is usually designed with metal mounts. From a Western point of view the ultimate effect of both these furniture designs is stylized. The structure and decoration issues are combined in a way that is both naïve and refined. The patched up appearance is an outcome of the way that the individual members do not seem to have been affixed by use of either glue or screws, but are mortised into one another and locked into position in the manner 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 display a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between the layers, stitched to show up a pattern of tiny pads. The front board and a corresponding board from the back could be folded after loosening some little iron hooks. Therefore the chair was a portable piece of furniture when traveling which, in the same time, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is seen in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair may also be found in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not held that the innovation actually originated in The Netherlands. Normally, 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 crafted in impressive amounts, as evidenced from one of Abraham Bosse’s engravings, in which an entire row of these chairs lined up along a wall. The form asserts itself with its shapely proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, to say, as developed in Paris around 1750—disseminated through most of Europe and was imitated or copied into the mid-20th century. The style owes its popularity to a combination of relaxation and charm. The seat conforms to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of fairly thick density; but all the members are deeply molded, all extra wood has been cut away, and finer designs might be further embellished with very delicate and decorative carving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for all of the upholstery on the seat, back, and armrests; cane is occasionally used in place of upholstery.

English chairs of the 18th century were more open in form than the French. The French manner for stylistic uniformity, which lead from the royal circles in Paris and Versailles throughout most of France and became the favourite 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 popular and was widely distributed throughout the world.

Late 18th to 20th century
During 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 styles 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 figures from which accounts are prepared but is a distinct process, prior to accounting.

Predominantly, bookkeeping records two parts of information: (1) the current value, or equity, of the enterprise and (2) the changes in value—profit or loss—taking place in the business from a given period.

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

Bits and pieces of financial and numerical charts are uncovered for nearly every group of people with a commercial history. Records of commercial contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The two-entry style of bookkeeping came up with the development of the enterprising republics of Italy, and tutorial manuals for bookkeeping were created in the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial books a necessity. The past of bookkeeping, in fact, closely resembles the history of commerce, industry, and government and, partially, assisted in forming it. The worldwide expansion of industrial and commercial activity required higher cosmopolitan decision-making processes, which in turn demanded higher sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government regulation became more detailed and resulted in even greater requirement for information; business firms had to provide information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the requirement for bookkeeping for their own departmental operations went up.

Although bookkeeping procedures can be very complex, it is all based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger must have the information of individual accounts. The daily records in the journals are put in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of those changes that took place in the ownership equity due to the operations of the period. The balance sheet provides the financial condition of the business at the particular point with regard to assets, liabilities, and the ownership equity.

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields 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.
