The common question heard when acquiring a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and types available, it can be difficult for the buyer to make a decision between both technologies. It comes down to the fact that LCD projectors offer far better image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with bringing up the same standard of image quality.

It’s like a set of blinds in your room on your bedroom window. With the twist of a rod you can have the shutters open or closed, depending on whether you want to let light in or not. And such is exactly how an LCD projector operates. Each pixel operates like its own shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the pros 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 switches on to when the image reaches your screen is absolutely significant to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by splitting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 individual LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. Something to remember about LCD projectors is that all three colours are projected onto your screen at once. The way a DLP projector works is widely different and even the way an image comes out 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 making an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s vision will then draw each coloured element of the image into a single complete image. With LCD projectors, all colours are available all the time to form the best brightness and superb colour accuracy. In DLP, only one colour is available at a time, causing lower colour brightness and accuracy. Some manufacturers have added a white segment for the colour wheel to improve all over brightness, but this then damages colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and thus must be better quality. 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 possess high contrast specifications in comparison to most LCD projectors. At first glance, this appears to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room while the projector is in use. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to see needs moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector displays 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 pulled up. LCD projectors do not have this downside because all the colours are delivered at once. DLP developers have created 3DLP solutions using 3 chips to answer the colour break up artifacts, but the price tag of these projectors make them not practical for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they compensate for the refractive qualities of light. Jump back to high school science, and they taught you how the various colours of light refract different amounts when directed through the same lens. The downfall with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Generally with a DLP projector, an extra yellow colour will come through above and some extra blue will appear below an image containing something as simple as a straight black line. In building LCD projectors can be set to remove these effects on the projected image, as each colour is processed on a separate LCD panels.

The sole real benefit (excluding price) with picking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transport and has to be traded off against the image advantages of LCD projectors. If resulting picture quality is important to you, then the choice is easy. Go for an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image mistakes.

As the Dutch found preeminence in sea power during the 17th century, the initial yacht had been a leisure craft used mostly by royalty and later by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private challenges. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting became fashionable with the rich and aristocracy, but after that point the trend did not last.

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

Yacht racing was first seen in some organized fashion 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 the throne in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing 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 patronage made the Solent – the strait between the mainland and the Isle of Wight – the continuing site of British yacht racing. The organisation at Cowes became the Royal Yachting Club, again at the accession of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing tests for high bids were held, and the club life was splendid. Ultimately Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was for the most part for leisure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled 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 society, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens instigated 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 until the later half of the 19th century. The style of large yachts was first heavily affected by the success of America, which was drawn by George Steers for a club started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. Earlier yachts were not designed and manufactured in today’s sense, with merely a model for an outline. Not until the second half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the use of the study of aerodynamics do for the design of sails and rigging what such science had already done for hulls.

Because most of all sailboats had to be individually custom-built, there arose a desire for handicapping boats before the one-design class boats were designed. Thus, a rating rule was decreed, which is found in the International Rule, adopted in 1906 and edited in 1919. Today, one of the most rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are created to standard specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between such boats can be done on an even keel with no handicapping at all. A perfect example is the generic International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

As long as yachting belonged mostly for the aristocracy and the rich, expense was no problem, and the size of boats increased, in both length and weight. The rise 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 voyage around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of smaller craft. Later in the 20th century, for the larger part after World War II, smaller racing and recreational boats became more common, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, during which steam began to emulate sail power in commercial boats, the steam engine, and later the internal-combustion engine, were employed more and more in personal craft. Large power yachts were developed to a high degree, and long-distance sailing was a preferred pastime of the wealthy. The early power yachts were paddle-wheel boats; they then gave rise to those powered by the completely submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries carrying both sail and power were the yacht fashion for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the large part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the construction of more sizeable steam yachts. Conspicuous within 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 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 was used in active service during World War II.

As larger and better quality internal-combustion engines were created, many big yachts began using them for power. The creation of the diesel engine, using heavy oil for fuel, was furthered during World War I. From the decade after, bigger power-yacht building blossomed, reaching a climax in the Orion (1930) at 3,097 tons. From that period the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power boats fell away from 1932, and the style after that was toward smaller, less expensive craft. From World War II, lots of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a widespread beloved competition enjoyed by thousands of yachtsmen individually sailing and keeping their own small leisure yachts. The amount of craft and sailors has increased steadily, not only in the traditional areas by the beach but also on inland waterways and lakes.

Taxes can be differentiated by the impact they have on the placement of income and wealth. A proportional tax is one that puts the same relative burden on all the taxpayers—i.e., in the case where tax liability and income move in equal levels. A progressive tax is characterizable by a higher than proportional growth in the tax burden in regard to the rise in income, and a regressive tax is recognised by a less than proportional increase in the comparable burden. Ergo, progressive taxes are regarded as fighting inequalities in income distribution, while regressive taxes may have the effect of an increase in these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so within the upper-income class—especially if a taxpayer is able to reduce his tax base by claiming deductions or by leaving out particular income aspects from his taxable income. Proportional tax rates if 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 offer the most appropriate measure of taxpaying ability. For example, transitory increases in income could be saved, and during temporary declines in income a taxpayer may choose to provide for consumption by reducing savings. Ergo, if taxation is made comparable along with “permanent income,” it will be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (save those on luxuries) tend to be regressive, because the spread of one’s income consumed or spent for a specific good lessens as the level of personal income grows. Poll taxes (also known as head taxes), nominated as a flat amount per capita, obviously are regressive.

It is difficult to classify 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 nominating who bears the tax burden depends crucially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In analysing the economic purposes of taxation, it is necessary to distinguish between various concepts of tax rates. The statutory rates will include those specified in law; often these are marginal rates, but in some cases they are mean rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income rises by one dollar. Ergo, if tax burden increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax laws generally contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates should regard provisions other than 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 more than indicated by the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate applicable to income from business and capital, since it may be reliant on such considerations 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 show the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are permitted for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households can swamp these effects, forcing regressivity, as signified by average tax rates that lower as income increases.

The LCDs put for projection systems are typically small reflective or transmissive panels illuminated by a powerful arc lamp source. A number of lenses enlarges the reflected or transmitted image then sends it onto a screen. In front-projection systems the LCD is placed on the same area of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of more expense and performance can use three distinct LCD panels, reflecting separate red, green, and blue images that mesh to make a coloured image on the screen.

The increasing need for visual presentations has had a special emphasis on the switching speed of liquid crystals. This has necessitated the development of objects using smectic liquid crystals, particular types of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. In it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and within the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal has optically active molecules, and a subtle result of the optical activity and the tilt 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 through the plane of the layers. Therefore, there is a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The corresponding change in optical properties can cause a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been commercialized for larger passive-matrix displays, but their high cost and complex nature has hindered them from creating any significant progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as parts in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be made use of in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick succession (around 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state between the red and green periods but to a nontransmissive state during the blue period, displaying the end 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 the majority of other pieces (apart from the bed) are created to support objects, the chair supports the human form. The term chair is meant to be said here in the largest sense, from stool to throne to derivative kinds including a bench or sofa, which may be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously labeled.

The social history of the chair is as curious as its history as art and craft. The chair is not just a physical support and/or aesthetic piece; it historically was an indicator of social hierarchy. At the Medieval royal courts there were important distinctions between having a chair with arms, or a chair with a back but no arms, or worse having to squat on a stool. From the recent century, a director’s and/or manager’s chair has been seen as an indicator of superior rank, and in democratic government meeting the speaker sits on a raised platform.

In its furniture purpose, the chair is used for a wealth of various purposes. There are chairs created to attend to man’s age and physical form (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). From past times there were chairs used for birthing (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). We design chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded, chairs on wheels, and chairs on runners.

Contemporary lifestyle has demanded new chairs for use in automobiles and aircraft. All these chair kinds has adapted to suit to differing human desires. For its unique connection with man, the chair lives to its full purpose only when in employ. While it doesn’t make any difference to one’s appreciation of a cupboard or a chest of drawers whether there are things inside or not, a chair is seen best and evaluated with a person sitting on it, for chair and sitter require one another. Thus the individual limbs of a chair were given labels according to the areas of a human form: arms, legs, feet, back, and seat.

Because the simple role of the chair is to support the human body, its credit is judged generally by how completely it does fulfill this practical use. In the construction of a chair, the chair maker is restricted in certain static regulations and principal measurements. In these regulations, however, the chair creator has extensive freedom.

The history of the chair lasts over an epoch of several thousand years. There existed societies that had made iconic chair shapes, as seen of the leading endeavour in the industries of handling and creativity. In these such cultures, individual mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of masterful make, are today known from findings made in tombs. First of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs shaped not unlike those of a chosen animal, a curved seat, and with a sloping back supported from vertical stretchers. From this a stable triangular construction was obtained. There was from our view no particular differentiation from the creation of Egyptian thrones and chairs for typical non-royals. The simple change was in the intricacy of its ornamentation, in the particulars of expensive inlays. The Egyptian folding stool probably was developed as an easily packed seat for army officers. As a camp stool that type stayed around for much later periods of time. But the stool also was made for the use of a ceremonial seat, its mechanical task as a folding stool fast forgotten. This can today be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the form of folding stools but are not able to be folded as the seats are made out of wood. The simple construction of the folding stool, being of two frames that turn on metal bolts and hold a seat of leather or fabric fastened between them, then appeared but somewhat later as the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of these is the folding stool, from ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is found not from any ancient item still in form but as found in a wealth of pictorial objects. The significant kind is the klismos seen on the Hegeso Stele at the Dipylon burial ground by Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of them are seen. These curving legs were possibly executed with bent wood and were probably had to bear huge pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat would have had to be therefore extremely strong and were visibly indicated.

The Romans borrowed from the Greek design; some models of seated Romans show examples of a more heavyset and are a kind of more crudely constructed klismos. Both types, the light or heavy, were brought back in the Classicist time. The klismos influence is known in French Empire furniture, in English Regency, and in some special forms of marked originality in Denmark and Sweden circa 1800.

China
The progression of the chair in China cannot be followed as far back as in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged collection of images and artworks had been preserved, with images of the interiors and exterior of Chinese households and the furniture. Kept also from the 16th century are a collection of chairs made of wood or lacquered wood, that show an amazing similarity to pictures of ancient chairs.

Just the same as in Egypt, there existed two major chair designs in China: a chair with four legs and a folding stool. That four-legged chair is designed both with or without arms although always with a square seat and straight stiles (vertical side supports) to hold up the back. In one image, though, the stiles could be delicately curved above the arms in order to suit the structure of the S-shaped back splat (the basic upright of its back). Together, the three limbs are mortised on the yoke-like top rail. Though the idea of this back splat had an introduction for English chairs within the Queen Anne period, wooden items that would only to a restricted limit stabilise corner joints (as well as being loose additionally) are an element solely to Chinese chairs. The four legs are set through the seat frame, which stops around the rounded staves. Every member is round in section or possesses rounded edges—referable maybe to the bamboo tradition. The seat is not comfortable and might have had a plaited form. These chairs needed the sitter to remain stiff and upright; for if too much weight is exerted on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this era armchairs likely were allowed only for the senior persons, for they were esteemed greatly.

The Chinese folding stool is believed to have been brought to China from the West. It is akin much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is elegantly affixed to the two legs of the stool by means of a curved member, which is usually provided with metal mounts. From a Western viewpoint the resulting effect of both these furniture styles is stylized. The construction and aesthetic parts 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 parts do not appear to have been held together by either glue or screws, but were mortised with one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its signature on the chair. Works of art project a design 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 bring out a pattern of little pads. The front board and a similar board in the back could be folded after loosening some small iron hooks. In this way the chair was an easily portable piece of furniture when traveling which, at the same time, held the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be seen in engravings of the interiors 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 is also made in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the style actually was born in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of slender shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in impressive quantities, as evidenced from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up along a wall. The form asserts itself by its elegant proportions and delicate 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 styles—that is, as progressed in Paris around 1750—conquered most of Europe and was imitated or copied into the mid-20th century. The style owes this popularity to a combination of comfort and elegance. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are stable, constructed on craftsmanlike methods even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those employ wood of quite thick density; but every member is deeply molded, all extra wood has been cut away, and more expensive examples would be further embellished with highly delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for the upholstery on the seat, back, and armrests; canework is in some cases used rather than upholstery.

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

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping grants the information from which accounts are written but is a different process, required prior to accounting.

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

Management officials, investors, and credit grantors all have to have such information: management in order to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to analyse the results of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to assess the financial statements of an entity in finding whether to allow a loan.

Bits and pieces of financial and numerical records are uncovered for almost every country with a commercial history. Records of trade contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The two-entry manner of bookkeeping began with the progression of the business republics of Italy, and tutorials for bookkeeping were developed during the 15th century in various Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial books a requirement. The past of bookkeeping, in fact, reflects the past of commerce, industry, and government and, in some part, assisted in forming it. The worldwide movement of industrial and commercial activity needed more sophisticate decision-making procedures, which itself needed greater sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government legislation became more significant and resulted in higher need 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 in size, and the demand for bookkeeping for their own departmental operations went up.

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

At the end of each month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The duty of the income statement or profit-and-loss statement is to present an analysis of those changes that occurred in the business equity because of the transactions of the period. The balance sheet shows the financial condition of the entity at the particular day 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 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 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.
