The most common question that is asked when purchasing a new projector for the home, office, or classroom is: would I buy an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and types available, it can be challenging for clients to choose between these technologies. Ultimately LCD projectors give far better image quality and colour accuracy. The next paragraph tells you why DLP projectors struggle with creating a similar rate of image quality.

Think of a set of blinds in your household on your bedroom window. By a twist of a rod you can make the shutters open or closed, depending on whether you want to let light in or not. And such is exactly how an LCD projector functions. Each pixel works like an individual 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 experts like to call them. Each pixel element works 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 picture reaches your screen is absolutely important for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting it into red, blue and green components, by three mirrors which send the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by turning each pixel on and off. The pixels are then projected in a glass prism to send the projector image. Something important to remember about LCD projectors is that all three colours are sent onto your projector screen at the same time. The way a DLP projector works is very different and even the produced image shows up is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image forms a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to construct the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into a whole image. From LCD projectors, all colours are available all the time to create the highest brightness and great colour accuracy. In DLP, only one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some DLP manufacturers have included a white segment for the colour wheel to improve brightness generally, but this also detracts from colour accuracy.

I hear in forums all the time that DLP offers a higher contrast ratio and therefore must be better 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 able to produce. DLP projectors do have high contrast specifications as compared to the majority of LCD projectors. At one glance, this can seem to be an advantage, however, in reality, the true black level is determined by the ambient light in the room where the projector is being utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you want to view requires moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most often seen 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 keep changing between the time red, blue and green colours are shone. LCD projectors do not have this characteristic because all the colours are projected at once. DLP builders have formed 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the price tag of these projectors make them not practical for the majority of businesses and consumers.

Another 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 the different colours of light refract different amounts when shone through the same lens. The problem with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Usually with a DLP projector, some extra yellow colour will appear above and some blue will come through below an image as simple as a straight black line. In building LCD projectors can be set to reduce these effects on the projected image, because each colour is directed on isolated LCD panels.

The sole real buy point (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant with regard to transport and must be traded off against the image superiority of LCD projectors. If overall picture quality is important to you, then the choice is a no-brainer. Go for an LCD projector! LCD projectors will definitely make bright, colourful images with fewer image errors.

As the Dutch found dominance in sea power during the 17th century, the initial yacht became a pleasure craft used mostly by royalty and later by the burghers for the canals as well as the protected and unprotected waters of the Low Countries. Yacht 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 restoration to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting rose as classy among the rich and nobility, but after that period the fashion did not last.

The first yacht group in the British Isles, the Water Club, was instigated in about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with large naval panoply and formality. The closest thing to a race was the “chase,” in which the “fleet” pursued an imagined enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, when merging with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered fashion on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British yacht racing. The society at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing matches for great stakes were held, and the society life was lovely. Eventually Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English held control. Sailing was largely for fun and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and sophistication for the later yachts in those waters from the late 19th century. The first persisting American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The design of sizeable yachts was initially largely put upon by the success of America, which was drawn 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 win at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with just a model for an outline. Not until the second half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the use of the research of aerodynamics do for the craft of sails and rigging what it had done earlier for hulls.

Because almost all sailboats were individually custom-built, there was a need for handicapping boats as this was previous to the one-design class boats were made. Therefore, a rating rule was written, which is found in the International Rule, adopted in 1906 and revised in 1919. In modern times, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to the same dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between these boats can be held on an even basis with no handicapping at all. 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 an activity largely for the nobility and the rich, cost was no issue, and the size of boats developed, in both length and weight. The ascendancy and preference of smaller yachts happened in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of smaller boats. Thereafter in the 20th century, notably after World War II, smaller racing and pleasure craft became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, at which point steam began to replace sail power in market boats, the steam engine, and later the internal-combustion engine, were employed increasingly in personal vessels. Large power yachts were furthered to a high standard, and long-distance sailing turned into a fond activity of the well off. The first power yachts were paddle-wheel boats; these then gave way to boats powered by the completely submerged screw or propeller sort of propulsion. Like naval and merchant yachts, auxiliaries possessing both sail and power were the yacht standard for many years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were solely power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of more sizeable steam yachts. Conspicuous of these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of over 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service during World War II.

As larger and better quality internal-combustion engines were produced, many big boats began using them for power. The establishment of the diesel engine, employing heavy oil for fuel, progressed from World War I. From the decade that followed, big power-yacht manufacture grew, climaxing in the Orion (1930) at 3,097 tons. In that point the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power boats declined after 1932, and the fashion after that was for smaller, less costly yachts. Following World War II, a lot of small naval boats were sold to private owners for conversion to yachts. At the late 20th century, yachting is a widespread loved sport enjoyed by thousands of yachtsmen individually manning and keeping their own small pleasure yachts. The amount of yachts and yachtsmen has increased steadily, not only in the traditional places by the sea but also on inland waterways and lakes.

Taxes are differentiated by the effect they have on the placement of income and wealth. A proportional tax is a kind that places the same relative requirement on every taxpayer—i.e., in the case where tax liability and income grow in the same proportion. A progressive tax is recognisable by a greater than proportional increase in the tax burden in regard to the growth in income, and a regressive tax is characterized by a less than proportional increase in the comparable burden. Hence, progressive taxes are viewed as removing a lack of equality in income distribution, but regressive taxes are found to have the effect of increasing these inequalities.

The taxes that are normally considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so for the upper-income group—especially if a taxpayer is able to reduce his tax base by declaring deductions or by removing some certain income aspects from his taxable income. Proportional tax rates that are applied to lower-income categories can also be more progressive if personal exemptions are made.

Income measured over the course of a given year might not absolutely come up with the most appropriate measure of taxpaying status. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may decide to pay for consumption by taking from savings. Thus, if taxation is regarded with “permanent income,” it will be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (save luxuries) are usually regressive, because the share of one’s income consumed or spent on a specific good declines as the amount of personal income is raised. Poll taxes (aka head taxes), levied as a set amount per capita, obviously are regressive.

It is hard to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of a lack of certainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests essentially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In assessing the economic purpose of taxation, it is necessary to distinguish between several ideas of tax rates. The statutory rates will include those specified in legislature; usually these are marginal rates, but sometimes they are mean rates. Marginal income tax rates denote the fraction of incremental income taken by taxation when income increases by one dollar. So, if tax liability rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislation commonly contain graduated marginal rates—i.e., rates that increase as income rises. Structured analysis of marginal tax rates should take into account provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than indicated within the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the relevant ones for regarding incentive effects of taxation. It is even more complicated to nominate the marginal effective tax rate to apply to income from business and capital, as it may rely 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 zero under a consumption-based tax.

Average income tax rates indicate the portion of total income that is taken 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 grows with income. Average income tax rates commonly grow with income, both because personal allowances are provided 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 could dampen these effects, allowing regressivity, as indicated by average tax rates that decline as income increases.

The LCDs used for projection systems are generally small reflective or transmissive panels lit by a forceful arc lamp source. A line of lenses enlarges the reflected or transmitted image and sends it onto the screen. In front-projection systems the LCD is located on the same side of the screen as the viewer, but in rear-projection systems the screen is lit from behind. Projectors of more expense and capacity might be found with three separate LCD panels, casting separate red, green, and blue images that blend to reflect a coloured image on the screen.

The growing need for video presentations has granted a special emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices utilizing smectic liquid crystals, certain ones 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 sophisticated smectic device. With it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and within the layers the molecules are on a tilt, as demonstrated in the figure. The host liquid crystal has optically active molecules, and a slight outcome of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. Therefore, there exists a permanent charge separation throughout 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 by doing so reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been marketed for big passive-matrix displays, but their expense and complex detail has hindered them from creating any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as parts in projection systems or as viewfinders in digital cameras. Their fast reacting allows them to be used in time-sequential colour systems, in which high cost colour filters are replaced with a coloured backlight that flashes red, green, and blue in quick pulsing (approx 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods then to a nontransmissive state for the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

Out of all furniture forms, the chair may be the paramount one. While most of the other objects (apart from the bed) are intended to support objects, the chair supports our human form. The term chair should be viewed here in the most general sense, from stool to throne to complex kinds such as a bench and sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinuishable.

The social history of the chair is as curious as its history as a creative craft. The chair is not just a physical support and aesthetic creation; it historically was symbolic of social rank. In the Medieval royal courts there were clear differences between being seated on a chair with arms, or a chair with a back but without arms, and having to make do with a stool. In the last century, a director’s or manager’s chair has been seen as iconic of superior status, and even in democratic government meeting the speaker sits on a higher level.

In its furniture form, the chair encompasses a range of various models. There are chairs created to attend to man’s age and physical capabilities (the high chair, the wheelchair) and to denote his status in society (the executive chair, the throne). From historical days there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs for ending life (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 make chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has designated special chairs in automobiles and aircraft. All these chair types has been adapted to conform to changing human desires. Due to its close link with man, the chair appears to its full importance only when being used. While it isn’t relevant to one’s appreciation of a cupboard or a set of drawers if there is anything inside or not, a chair is seen best and fairly judged with a person sitting on it, because chair and sitter require one another. Thus the different parts of a chair have been labeled as the names of the human parts: arms, legs, feet, back, and seat.

Because the obvious function of a chair is to support the body, its credit is valued primarily from how fully it does fulfill this practical role. In the construction of the chair, the maker is limited within particular static regulation and principal measurements. Inside these limitations, however, the chair builder has marvellous freedom.

The history of the chair extended over a period of several thousand years. There are societies that had made distinctive chair forms, seen of the premier task in the areas of skill and design. Within those societies, special note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of careful scheme, are now known from discoveries made in tombs. The first of the two 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 an animal, a curved seat, and with a sloping back supported from vertical stretchers. From this a strong triangular structure was obtained. There was from our knowledge no notable change from the structure of Egyptian thrones and chairs for typical peasantry. The main change existed in the intricacy of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool in all probability was created as an easily packed seat for army officers. As a camp stool that type persisted during much later periods. But the stool then was created for the role of a ceremonial seat, its mechanical history as a folding stool neglected or forgotten. This can now be found, 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 shape of folding stools but aren’t able to be folded as the seats were made with wood. The plain structure of the folding stool, consisting of two frames that rotate on metal bolts and bear a seat of leather or fabric fastened between them, also appeared some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this form is the folding stool, of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not with any ancient specimen still around but from a variety of pictorial objects. The best known is the klismos depicted on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those are visible. These curved legs were thought to have been manufactured with bent wood and were probably needed to bear a large amount of pressure under the weight of the sitter. The joints joining the legs to the frame of the seat are therefore super stable and were particularly denoted.

The Romans emulated the Greek chair; existing models of seated Romans offer chairs of a denser and in appearance slightly less intricately designed klismos. Both features, the light or the heavy, were revived in the Classicist period. The klismos influence is found in French Empire design, in English Regency, and in particular forms of marked individuality within Denmark and Sweden from 1800.

China
The past of the chair in China can not be traced as far as the progression of the chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an undamaged series of images and artworks has been protected, with images of the interior and exterior of Chinese homes and the furniture. Also kept of the 16th century are a trove of chairs constructed from wood or lacquered wood, that bear an astonishing similarity to designs of older chairs.

Just the same as in Egypt, two particular chair forms existed in China: a chair having four legs and a folding stool. This chair can be found both with and without arms but never missing a square seat and straight stiles (upright side supports) to give support to the back. In one design, it has been found, the stiles were marginally curved by the arms to suit the shape of the S-shaped back splat (the main upright of the back). The three areas are mortised into the yoke-like top rail. Although the design of the Chinese back splat later had an influence on English chairs in the Queen Anne period, wooden members that could merely to a particular limit embolden corner joints (as well as being loose into the bargain) are an element exclusive to Chinese chairs. The four legs sit through the seat frame, which closes upon the rounded staves. All the members are round in section or possesses rounded edges—referable maybe to the bamboo tradition. The seat is not comfortable and occasionally had a plaited texture. These chairs needed the sitter to stay stiff and upright; for if too much pressure is pushed on the back, the chair has a way of falling over. In patriarchal Chinese houses of this era armchairs most likely were kept only for older persons, for they were greatly respected.

The Chinese folding stool is understood to have come to China from the West. It is not dissimilar very much from the Egyptian and Scandinavian folding stools, but it has a dissimilarity in that the top rail is prettily fixed to the two legs of the stool by means of a curved member, which is often provided with metal mounts. From a Western understanding the ultimate effect of these two furniture designs is stylized. The constructive and aesthetic elements are combined in a way that is all at once both naïve and refined. The pieced-together appearance is a result of the way that the individual items do not appear to have been fixed by means of either glue or screws, but had been mortised with one another and fixed in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its name on the chair. Paintings display a kind of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to produce a pattern of little pads. The front board and a related board from the back could be folded after unscrewing some small iron hooks. Thus the chair was an easily portable piece of furniture for traveling which, in the same time, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is displayed in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair can also be found in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the style actually began in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of thin shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in vast quantities, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up against a wall. The design asserts itself with its shapely proportions and expensive upholstery in gilt leather or fabric framed 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—disseminated through most of Europe and has been imitated or copied in the mid-20th century. The chair owes its popularity to a combination of relaxation and elegance. The seat suits to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are solidly constructed on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of quite thick dimensions; but every member is deeply molded, all extra wood has been sanded away, and more expensive examples can be further embellished with intricately delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all the upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

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

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

Late 18th to 20th century
Within the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

In cheaper versions of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

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

Bookkeeping is the recordkeeping of the money values of the transactions of a business. Bookkeeping creates the information from which accounts are written but is a separate process, prerequisite to accounting.

Predominantly, bookkeeping finds two kinds of information: (1) the current value, or equity, of the enterprise and (2) the change in value—profit or loss—taking placement in the enterprise during a single time.

Management officials, investors, and credit grantors all require this kind of 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 regarding buying, holding, and selling securities; and credit grantors in order to assess the financial statements of a business in assessing whether to grant a loan.

Bits and pieces of financial and numerical record charts can be found for almost every nation with a commercial background. Records of trading contracts have been found in the ruins of Babylon, and accounts for both farms and estates have been made in ancient Greece and Rome. The double-entry manner of bookkeeping came with the furthering of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were developed during the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a paramount factor. The ancestry of bookkeeping, in fact, closely reflects the ancestry of commerce, industry, and government and, partially, assisted in shaping it. The international market of industrial and commercial activity called for more cosmopolitan decision-making methodology, which in its turn called for greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislature became more detailed and resulted in greater requirement for information; firms had to provide information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for their own operations went up.

While bookkeeping methods can be very detailed, all are based on two kinds of books used in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, etcetera), and the ledger must have the information of individual accounts. The daily records from the journals are entered in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to give an analysis of those changes that have taken place in the business equity because of the operations of the period. The balance sheet provides the financial situation 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.
