The most common question that is asked when buying a new projector for the home, office, or classroom is: do 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 commonplace projector imaging technologies. With so many brands and types available, it can be challenging for consumers to pick between those technologies. The fact is that LCD projectors provide far superior image quality and colour accuracy. The next paragraph tells you why DLP projectors struggle with reproducing a similar standard of image quality.

Think of a set of blinds in your household covering 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 works. Each pixel operates like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point at which the projector is switched on to when the image reaches your screen is absolutely important with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which direct the coloured light to 3 separate LCD panels. The 3 LCD panels form the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to send the projector image. Something important to understad about LCD projectors is that all three colours are directed onto your wall at once. The way a DLP projector works is vastly different and even the produced image appears is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce 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 combine each coloured element of the image into a single whole image. Using LCD projectors, all colours are available all the time to offer top brightness and fantastic colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some designers have put a white segment for the colour wheel to improve all over brightness, but this goes and detracts from colour accuracy.

I hear in forums all the time that DLP offers a higher contrast ratio and as such 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 projector is capable of. DLP projectors do have high contrast specifications as compared to the majority of LCD projectors. At a glance, this appears to be a plus, however, in the real world, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you plan to see has moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this characteristic because all colours are sent at the same time. DLP developers have created 3DLP solutions using 3 chips to solve the colour break up problem, but the cost of these projectors make them not practical for most businesses and consumers.

Another point of difference 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 different colours of light refract various amounts when shone through the same lens. The downfall with DLP projectors is that they have the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Most of the time with a DLP projector, some yellow colour will come through above and some blue will be projected below an image containing something as simple as a single black line. In manufacturing LCD projectors can be set to remove these effects on the projected image, because each colour is processed on isolated LCD panels.

The isolated veritable advantage (excluding price) with choosing a DLP projector is its smaller overall size and weight. However, this is only relevant with regard to transporting the device and must be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is vital to you, then the answer is easy. Take an LCD projector! LCD projectors will always produce bright, colourful images with fewer image blips.

As the Dutch found dominance in sea power during the 17th century, the early yacht became a pleasure craft used initially by royalty and later by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, coming out of private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy 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 returning, on a £100 punt. Yachting was found to be fashionable among the rich and nobility, but after that time the fashion did not last.

The first yacht association in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had much naval panoply and rigour. The closest thing to racing 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 groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered manner on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group 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 continuing site of British yacht racing. The association at Cowes became the Royal Yachting Club, also at the accession of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the social life was superlative. Eventually Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English held power. Sailing was for the most part for pleasure and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a minimum of luxury and elegance for the later yachts in the area from the late 19th century. The first continuing American yacht association, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The design of large yachts was originally greatly affected by the victory of America, which was designed by George Steers for a group 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. The first yachts were not designed and crafted in a contemporary sense, with merely a model used. Not until the second half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the use of the research of aerodynamics do for the craft of sails and rigging what it had already done for hulls.

Because most of all sailboats had been individually custom-built, there was a desire for handicapping boats previous to the one-design class boats were designed. Thus, a rating rule was written, which is found in the International Rule, adopted in 1906 and edited in 1919. In the present day, one of the rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are built to single requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing such boats can be done on an even par with no handicapping necessary. A perfect example is the generic International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

For the time that yachting was done largely for the nobility and the rich, expense was no problem, and the size of boats developed, in both length and weight. The promotion and popularity of smaller boats came in the latter half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of less sizeable yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and leisure craft 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, in which steam started to replace sail power in commercial craft, the steam engine, and later the internal-combustion engine, were employed increasingly in pleasure vessels. Sizeable power yachts were furthered to a high degree, and long-distance sailing was a preferred activity of the well off. The first power yachts were paddle-wheel boats; these then gave rise to yachts powered by the wholly submerged screw or propeller kind of propulsion. As in the case of naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, many 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 rise in the construction of bigger steam yachts. Conspicuous among these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of more than 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 gave active service for World War II.

As larger and more reliable internal-combustion engines were created, many bigger craft were using them for power. The establishment of the diesel engine, employing heavy oil for fuel, advanced in World War I. In the decade after that, large power-yacht building flourished, reaching a climax in the Orion (1930) at 3,097 tons. From that time the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats declined in 1932, and the trend from then was in preference of smaller, less costly boats. Following World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. By the late 20th century, yachting has become a globally popular competition enjoyed by thousands of yachtsmen personally manning and keeping their own small leisure boats. The number of yachts and owners is increasing steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is the kind that impinges the same relative requirement on all the taxpayers—i.e., where tax liability and income increase in relative proportion. A progressive tax is recognised by a higher than proportional rise in the tax liability in regard to the growth in income, and a regressive tax is recognisable by a less than proportional growth in the relative liability. Ergo, progressive taxes are thought of as removing inequalities in income distribution, while regressive taxes might result in an increase these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, might become less so in the upper-income class—particularly if a taxpayer is able to reduce his tax base by declaring deductions or by leaving out some income aspects from his taxable income. Proportional tax rates which are applied to lower-income categories could also be more progressive if such personal exemptions are claimed.

Income measured over the period of a given year does not necessarily give the most accurate measure of taxpaying status. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may elect to pay for consumption by reducing savings. Therefore, if taxation is regarded along with “permanent income,” it can be less regressive (or more progressive) than when made comparable with annual income.

Sales taxes and excises (excepting luxuries) tend to be regressive, because the spread of one’s income consumed or spent for a specific good decreases as the level of personal income is raised. Poll taxes (also termed head taxes), levied as a set amount per capita, obviously are regressive.

It is not simple to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden lays crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In analysing the economic purpose of taxation, it is necessary to distinguish between differing concepts of tax rates. The statutory rates are those nominated in legislature; generally these are marginal rates, but for some cases they are mean rates. Marginal income tax rates denote the fraction of incremental income that is taken by taxation when income is increased by one dollar. Ergo, if tax liability increases by 45 cents when income grows 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 need to consider 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 growth in income, the marginal rate is 20 percentage points greater than indicated within the statutory rates. Since marginal rates display how after-tax income changes in response to changes in before-tax income, they are the important ones for regarding incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, since it may depend on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates show the portion of total income that is required in taxation. The pattern of average rates is the one that is in consideration for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly rise 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 predominantly by high-income households might swamp these effects, forcing regressivity, as signified by average tax rates that fall as income increases.

The LCDs put in projection systems are typically small reflective or transmissive panels illuminated by a bright arc lamp source. A series of lenses expands the reflected or transmitted image and then displays it on a screen. In front-projection systems the LCD is located on the same side of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of greater expense and capacity might have three distinct LCD panels, creating separate red, green, and blue images that combine to create a coloured image on the screen.

The increasing need for film presentations has had a special emphasis on the switching speed of liquid crystals. This has necessitated the development of objects employing smectic liquid crystals, some of which emit a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most complex smectic device. In it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are slanted, as displayed in the figure. The host liquid crystal contains optically active molecules, and a slight turn up of the optical activity and the angle 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. Thus, there exists a permanent charge separation over 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 therefore reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix presentations, but their cost and complexity has impeded them from making any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be employed in time-sequential colour systems, in which dear colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid pulsing (approximately 100 cycles every second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods but to a nontransmissive state during the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

From each of the furniture pieces, the chair may be the primary one. While most of the other forms (apart from the bed) are devised to support objects, the chair supports a human form. The term chair is meant to be regarded here in the widest sense, from stool to throne to complex chairs including a bench and sofa, which might be seen 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 interesting as its history as an art and craft. The chair is not simply a physical support and aesthetic object; it is also symbolic of social place. In the past royal courts there were plain connotations between being seated on a chair with arms, on a chair with a back but without arms, and having to make do with a stool. Since the last century, a director’s and/or manager’s chair has risen an identifier of superior dignity, like in democratic government debate the speaker sits on a high-set level.

As its furniture purpose, the chair is used for a number of different forms. There are chairs designed to match man’s age and physical abilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). In past days there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded up, chairs on wheels, and chairs on runners.

Modern day living has demanded special chairs in automobiles and aircraft. All these chair shapes has been perfected to match to changing human needs. From its unique connection with man, the chair exists to its full purpose only when being utilised. Though it does not make any difference to one’s appreciation of a cupboard or a set of drawers if there might be things inside or not, a chair is really seen and fairly judged with a person utilising it, for chair and sitter need the other. Thus the several parts of the chair have been given names according to the parts of our human parts: arms, legs, feet, back, and seat.

Because the primary role of the chair is to support our human body, its value is tested firstly for how completely it measures up to this practical role. In the build of the chair, the designer is limited for particular static laws and principal measurements. In these restrictions, however, the chair maker has extensive freedom.

The history of the chair lasted a period of several thousand years. There are civilizations that have created iconic chair types, expressive of the principal object in the spheres of handling and creativity. From such civilisations, particular note needs to be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of careful design, are today a finding from discoveries made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have had four legs designed similar to those of a particular animal, a curved seat, leading to a sloping back supported with vertical stretchers. From this design a durable triangular form was made. There appears to be no notable difference in the creation of Egyptian thrones and chairs for typical citizens. The only variation exists in the brand of ornamentation, in the particulars of pricey inlays. The Egyptian folding stool probably was crafted for an easily portable seat for soldiers. As a camp stool that kind persevered until much later points. But the stool also was created as the character of a ceremonial seat, its original history as a folding stool ignored or forgotten. This can today be observed, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the construction of folding stools but can’t be folded because the seats are formed of wood. The easy manufacture of the folding stool, composed of two frames that spin on metal bolts and support a seat of leather or fabric secured between them, appeared again some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this form is the folding stool, crafted out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not in any ancient specimen still existing but seen in a large amount of pictorial objects. The better recognised is the klismos seen on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, only two of them could be displayed. These curving legs were considered to be crafted of bent wood and were therefore subjected to huge pressure under the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very stable and were visibly pointed out.

The Romans emulated the Greek chair; designs of casts of seated Romans display designs of a more heavyset and in appearance slightly less intricately constructed klismos. Both features, the light or heavy, were popularised as part of the Classicist time. The klismos influence can be found in French Empire furniture, in English Regency, and in some types of profound uniqueness within Denmark and Sweden from 1800.

China
The past of the chair in China can not be tracked as far back as the progression of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken collection of sketches and artworks has been kept safe, with images of the interior and outside of Chinese homes and the designs of furniture. Also preserved from the 16th century are a collection of chairs constructed of wood or lacquered wood, that display an astonishing likeness to styles of past chairs.

As in Egypt, there were two iconic chair forms in China: a chair that had four legs and a folding stool. That chair has been seen both with and without arms though always having a square seat and straight stiles (vertical side supports) to firm the back. In one kind, however, the stiles are delicately curved over the arms in order to fit the structure of the S-shaped back splat (the main upright of a chairback). Together, the three sections had been mortised in the yoke-like top rail. While the style of the back splat exercised an inspiration for English chairs during the Queen Anne period, wooden sections that could merely to a limited limit embolden corner joints (and then are loose as a result) indicate an element exclusive to Chinese chairs. The four legs sit through the seat frame, which finishes about the rounded staves. Every member is round in section or has rounded edges—acknowledging perhaps to the bamboo tradition. The seat is not comfortable and might have had a plaited form. These chairs demanded of the sitter to be stiff and upright; for when too much pressure is exerted on the back, the chair has a way of toppling. In patriarchal Chinese homes of this period armchairs most likely were reserved for elderly individuals, for they were greatly esteemed.

The Chinese folding stool is thought to have taken to China from the West. It does not differ that much from the Egyptian and Scandinavian folding stools, but it has a variation in that the top rail is intricately fixed to the two legs of the stool by using a curved member, which is generally seen with metal mounts. From a Western point of view the resulting effect of both these furniture forms is stylized. The manufacture and decoration parts are combined in a manner that is simultaneously naïve and refined. The pieced-together appearance is a result of the fact that the individual items do not look to have been fixed 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 in the 17th century also put its mark on the chair. Artworks show a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between the layers, stitched to show up a pattern of small pads. The front board and a related board from the back could be folded after loosening some little iron hooks. Thus the chair was an easily portable piece of furniture for traveling which, at the same era, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be displayed in engravings of the interior of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not determined that the innovation actually was instigated in The Netherlands. Typically, the legs of the chair were smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was produced in impressive amounts, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up by a wall. The design asserts itself by its harmonious 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 brought out in Paris around 1750—disseminated over most of Europe and was imitated or copied during the mid-20th century. The design owes its popularity to a combination of relaxation and delicacy. The seat suits to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of quite thick dimensions; but each member is deeply molded, all extraneous wood has been removed, and more upmarket chairs may be further embellished with highly delicate and decorative woodwork. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all upholstery on the seat, back, and armrests; cane is occasionally used rather than upholstery.

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

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

Bookkeeping is the recording of the money values of the function of a business. Bookkeeping grants the numbers from which accounts are written but is a distinct process, preliminary to accounting.

Basically, bookkeeping finds two types of information: (1) the current value, or equity, of the entity and (2) the changes in value—profit or loss—taking placement in the business over a particular time period.

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

Traces of financial and numerical record charts have been uncovered for almost every state with a commercial background. Records of trading contracts were found in the archaelogy of Babylon, and accounts for both farms and estates had been held in ancient Greece and Rome. The dual-entry style of bookkeeping came up with the progression of the business republics of Italy, and tutorials for bookkeeping were created within the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial bookkeeping a must-have. The past of bookkeeping, in fact, reflects the history of commerce, industry, and government and, in part, helped in shaping it. The international revolution of industrial and commercial activity needed greater sophisticated decision-making methods, which then called for greater sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government regulation became more important and resulted in higher need 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 developed in size, and the need for bookkeeping for their inner departmental operations increased.

Although bookkeeping methods can be extremely complex, all of it is based on two styles of books used in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger contains the record of individual accounts. The daily records from the journals are written in the ledgers.

Each month, generally, an income statement and a balance sheet are prepared from the trial balance posted out of the ledger. The point of the income statement or profit-and-loss statement is to show an analysis of any changes that took place in the enterprise equity from the transactions of the period. The balance sheet displays the financial condition of the enterprise at a particular day taken 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 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.
