The common question heard when looking for a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many different brands and models available, it can be difficult for the buyer to choose between those technologies. The simple fact of the matter is that LCD projectors offer far superior image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with bringing up the same grade of image quality.

Think of a set of blinds in your household covering your bedroom window. By a twist of a rod you can turn 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 operates like an individual shutter on a set of blinds to either send light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the picture reaches your screen is absolutely important with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 different LCD panels. The 3 LCD panels create the elements of the image by shining each pixel on and off. The pixels are then combined in a glass prism to send the projector image. Something to understad about LCD projectors is that all three colours are projected onto your wall at the same time. The way a DLP projector runs is vastly different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of making an image forms a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into the single whole image. With LCD projectors, all colours are available all the time to form top brightness and great colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment into the colour wheel to improve brightness generally, but this further lessens colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and thus must be better quality. For those 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 technology is capable of producing. DLP projectors do provide high contrast specifications when compared to many LCD projectors. At a glance, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room while the projector is being utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to bring to life needs moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this downside because all the colours are delivered simultaneously. DLP designers have formed 3DLP solutions using 3 chips to solve the colour break up issue, but the expense of these projectors make them almost impossible 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. Take yourself back to high school science, and remember how various colours of light refract differing amounts when passing through the same lens. The disadvantage with DLP projectors is that they take the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light differently. Often with a DLP projector, some yellow colour will be projected above and a superfluous blue will come through below an image containing something as simple as a lone black line. In manufacturing LCD projectors can be set to minimize these effects on the projected image, as each colour is processed on isolated LCD panels.

The one true plus (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant to transport and cannot be traded off against the image benefits of LCD projectors. If overall picture quality is crucial to you, then the solution is easy. Choose an LCD projector! LCD projectors will consistently produce bright, colourful images with fewer image imperfections.

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht was a leisure craft used first by royalty and secondly by the burghers on the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private challenges. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure 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, reigned 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting rose as popular with the wealthy and royalty, but after that time the habit did not last.

The first yacht club in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and had large naval panoply and formality. The closest thing to racing boats was the “chase,” in which the “fleet” pursued an imaginary enemy. The club endured, largely as a social club, until 1765, and in 1828, when conglomerating with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized manner on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht association 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 setting of British yacht racing. The association at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing matches for great bets were held, and the social life was wonderful. It came to be that the 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 persisted when the English held dominance. Sailing was largely for leisure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The style of sizeable yachts was first greatly put upon by the victory of America, which was created by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. Earlier yachts were not designed and crafted in the modern sense, with only a model used. Not until the second half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the employment of the study of aerodynamics do for the craft of sails and rigging what it had done earlier for hulls.

Because most of all sailboats were individually built, there arose a requirement for handicapping boats before the one-design class boats were made. Hence, a rating rule was written, which resulted in the International Rule, taken on in 1906 and edited in 1919. In modern times, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are created to single requirements in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing such boats can be held on an even keel with no handicapping necessary. A perfect example is the generic International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting belonged primarily for the nobility and the wealthy, cost was no problem, and the size of boats increased, in both length and weight. The promotion and desire of smaller boats happened 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Following this in the 20th century, particularly after World War II, smaller racing and pleasure boats became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam began to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were employed increasingly in leisure yachts. Bigger power yachts were progressed to a high degree, and long-distance travel was a preferred occupation of the wealthy. The earliest power yachts were paddle-wheel boats; these then gave way to boats powered by the wholly submerged screw or propeller type of propulsion. As well as naval and merchant vessels, auxiliaries with both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, several yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of bigger steam yachts. In particular 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 saw active service in World War II.

As larger and more dependable internal-combustion engines were developed, many bigger yachts were using them for power. The establishment of the diesel engine, using heavy oil for fuel, was furthered for World War I. In the decade that followed, big power-yacht manufacture blossomed, hitting a climax in the Orion (1930) at 3,097 tons. From that period the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power craft fell away in 1932, and the style thereafter was in preference of smaller, less costly craft. After World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. By the late 20th century, yachting is a widespread popular sport enjoyed by thousands of yachtsmen personally manning and keeping their own small leisure boats. The number of boats and owners is increasing steadily, not only in the traditional areas on the beach but also on inland waterways and lakes.

Taxes are categorized by the effect they have on the placement of income and wealth. A proportional tax is one that impinges the same relative onus on all the taxpayers—i.e., when tax liability and income grow in the same levels. A progressive tax is recognisable by a greater than proportional increase in the tax liability in relation to the rise in income, and a regressive tax is recognisable by a less than proportional growth in the comparative burden. Thus, progressive taxes are regarded as reducing inequalities in income distribution, while regressive taxes might cause an increase in these inequalities.

The taxes that are generally considered progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so in the upper-income class—in particular if a taxpayer is permitted to lessen his tax base by declaring deductions or by leaving out some certain income elements from his taxable income. Proportional tax rates if applied to lower-income demographics can also be more progressive if personal exemptions are declared.

Income measured over the course of a given period might not absolutely offer the most suitable measure of taxpaying ability. For example, transitory growth in income might be saved, and in temporary declines in income a taxpayer might elect to finance consumption by taking from savings. Thus, if taxation is regarded along with “permanent income,” it will be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (save luxuries) tend to be regressive, because the dissemination of personal income consumed or spent for a specific good lowers as the rate of personal income grows. Poll taxes (aka head taxes), levied as a set amount per capita, obviously are regressive.

It is hard to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to 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 depends for the most part on whether a national or a subnational (that is, provincial or state) tax is being debated.

In considering the economic effects of taxation, it is necessary to distinguish between various ideas of tax rates. The statutory rates are specified in legislation; generally these are marginal rates, but in some cases they are median rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income is increased by one dollar. So, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax statutes often contain graduated marginal rates—i.e., rates that grow as income grows. Heavy analysis of marginal tax rates should review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points greater than indicated in the statutory rates. Since marginal rates indicate how after-tax income increases or decreases in response to changes in before-tax income, they are the necessary 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, as it may depend on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates determine the fraction of total income that is paid 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 grows with income. Average income tax rates commonly rise with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households can dampen these effects, producing regressivity, as shown by average tax rates that decrease as income increases.

The LCDs utilised for projection systems are most often small reflective or transmissive panels lit up by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image and then displays it onto the screen. In front-projection systems the LCD is located on the same area of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of more expense and capability can have three distinct LCD panels, reflecting separate red, green, and blue images that combine to form a coloured display on the screen.

The increase in requirement for visual displays has put a particular emphasis on the switching speed of liquid crystals. This has necessitated the creation of devices build with smectic liquid crystals, some types of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. Within it the liquid crystal molecules are cast in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are slanted, as illustrated in the figure. The host liquid crystal has optically active molecules, and a slight result of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. So, there must be 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 resultant change in optical properties can make a change from light to dark when one or more polarizers are used.

SSFLC devices have been commercialized for large passive-matrix presentations, but their cost and complex nature has stopped them from having any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as elements in projection systems or as viewfinders in digital cameras. Their immediate reacting allows them to be utilised in time-sequential colour systems, in which dear colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast speed (approx 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state in the red and green periods and to a nontransmissive state during the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

Out of each of the furniture needs, the chair could be the primary one. While many other pieces (save for the bed) are meant to support objects, the chair supports the human form. The term chair is looked upon here in the most general sense, from stool to throne to further forms like a bench and sofa, which can be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as interesting as its history as a creative art. The chair is not only a physical support and/or aesthetic object; it is historically a symbol of social rank. Within the historical royal courts there were clear distinctions between having a chair with arms, or a chair with a back but no arms, or having to cope with a stool. Since the 20th century, the director’s or manager’s chair has been seen as iconic of superior standing, like in democratic government debate the speaker sits on a high-set platform.

As a furniture construction, the chair can be used for a wealth of different models. There are chairs structured to suit man’s age and physical condition (the high chair, the wheelchair) and for his rank in society (the executive chair, the throne). During past times there were chairs used for birth (birth chairs); in the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, and 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.

Modern living has developed unique chairs for use in automobiles and aircraft. Each of these chair kinds has been changed to suit to evolving human requirements. Because of its unique connection with man, the chair lives to its full importance only when utilised. Whereas it does not make a difference to one’s appreciation of a cupboard or a dresser drawers if there is anything inside or not, a chair is understood and fairly regarded by a person using it, because chair and sitter suit one another. Thus the individual parts of the chair were labeled as the areas of a human body: arms, legs, feet, back, and seat.

Because the elemental purpose of your chair is to support our body, its value is tested primarily by how fully it fulfills this practical function. In the construction of the chair, the carpenter is restricted under certain static regulations and principal measurements. Through these rules, however, the chair maker has awesome freedom.

The history of the chair lasts over an era of several thousand years. There existed peoples that made unique chair shapes, expressions of the principal craft in the arenas of skill and aesthetics. Within these civilisations, particular 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of careful scheme, are today found from findings made in tombs. First of the two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have had four legs shaped akin to those of a chosen animal, a curved seat, and a sloping back supported by vertical stretchers. From this a solid triangular design was created. There was from our understanding no marked variation in the construction of Egyptian thrones and chairs for ordinary citizens. The general change lies in the intricacy of its ornamentation, in the particulars of more valuable inlays. The Egyptian folding stool probably was made to be an easily packed seat for army officers. As a camp stool this kind persevered until much later periods of time. But the stool then also was made for the role of a ceremonial seat, its technical task as a folding stool being forgotten. This can from today be found, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are constructed in the structure of folding stools but can’t be folded as the seats are created of wood. The plain make of the folding stool, consisting of two frames that cycle on metal bolts and support a seat of leather or fabric set between them, is seen at some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of this form is the folding stool, crafted out of ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not with any ancient fossil still in form but as in a trove of pictorial items. The best known is the klismos depicted on the Hegeso Stele at the Dipylon burial ground near Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of which are displayed. These curving legs were considered to be crafted of bent wood and were likely to have been put under huge pressure with the weight of the sitter. The joints holding the legs to the frame of the seat would have had to be therefore extremely strong and were overtly pointed out.

The Romans borrowed from the Greek design; quite a few casts of seated Romans offer examples of a denser and in appearance slightly crudely constructed klismos. Both types, the light and the heavy, were brought back within the Classicist period. The klismos influence is seen in French Empire chairs, in English Regency, and in some forms of notable individuality within Denmark and Sweden from 1800.

China
The past of the chair in China cannot be tracked as long as chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken collection of images and paintings was kept, detailing the inside and exterior of Chinese houses and their furniture. Kept also from the 16th century are some chairs constructed from wood or lacquered wood, that display an amazing familiarity to designs of ancient chairs.

Just the same as in Egypt, there existed two iconic chair forms in China: a chair of four legs and a folding stool. That chair was found both with or without arms although never missing its square seat and straight stiles (vertical side supports) to give support to the back. In one design, it has been seen, the stiles had been lightly curved on top of the arms to fit the structure of the S-shaped back splat (the central upright of a chairback). Together, all three areas were mortised on the yoke-like top rail. Though the innovation of this back splat had an inspiration for English chairs of the Queen Anne period, wooden sections that merely to a restricted ability reinforce corner joints (and were loose to top it off) signify a design particular to Chinese chairs. The four legs are set through the seat frame, which closes upon the rounded staves. All the members are round in section or possesses rounded edges—acknowledging maybe to the bamboo tradition. The seat is not comfortable and occasionally had a plaited bottom. These chairs required of the sitter to stay stiff and upright; when too much pressure is forced on the back, the chair has a tendency to fall. In patriarchal Chinese households of this period armchairs likely were reserved only for the senior people, for they were given great esteem.

The Chinese folding stool is believed to have come to China from the West. It does not vary so very much from the Egyptian and Scandinavian folding stools, but it possesses a change in that the top rail is prettily affixed to the two legs of the stool in a curved member, which is often provided with metal mounts. From a Western understanding the overall effect of both furniture forms is stylized. The manufacture and decorative aspects are combined in a style that is at the same time naïve and refined. The patchwork appearance is an upshot of the manner that the individual items do not appear to have been affixed by use of either glue or screws, but are mortised onto one another and fixed in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its signature on the chair. Paintings project a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to produce a pattern of little pads. The front board and a similar board from the back could be folded after unscrewing some tiny iron hooks. Thus the chair was a readily portable piece of furniture in traveling which, in the same time, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be evidenced in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair is also made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not decided that the innovation actually originated in The Netherlands. Usually, the legs of the chair will be smooth, round in section, and of thin shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in considerable numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is a row of such chairs lined up along a wall. The style 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 form—that was, as brought out in Paris around 1750—disseminated through most of Europe and was imitated or copied in the mid-20th century. The chair owes this popularity to a combination of leisure and charm. The seat adheres 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 tiny upholstered pads over the armrests. Smooth transitions are found between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of relatively thick dimensions; but every member is deeply molded, all extraneous wood has been sanded away, and more expensive chairs can be further embellished with special delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all of the upholstery on the seat, back, and armrests; cane is sometimes used as an alternative to upholstery.

English chairs from the 18th century were more varied in design than the French. The French manner for stylistic uniformity, which spread from the royal circles in Paris and Versailles through most of France and found favour 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 well-known and was widely distributed throughout the world.

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

In cheaper 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, purport that completely new chair forms will probably be evolved in the future.

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping grants the figures from which accounts are written but is a different process, preliminary to accounting.

Essentially, bookkeeping provides two kinds of information: (1) the current value, or equity, of an enterprise and (2) any changes in value—profit or loss—taking place in the entity during a single time period.

Management officials, investors, and credit grantors all demand this information: management so as to analyse the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshot of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an entity in finding whether to accept a loan.

Traces of financial and numerical charts have been found for just about every state with a commercial backbone. Records of commercial contracts have been found in the archaelogy of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The two-entry style of bookkeeping began with the development of the business republics of Italy, and manuals for bookkeeping were produced during the 15th century in several Italian cities.

In the late 18th and early 19th centuries, the Industrial Revolution gave an important stimulus to accounting and bookkeeping.

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial records a paramount factor. The ancestry of bookkeeping, in fact, closely reflects the past of commerce, industry, and government and, partially, helped to form it. The international market of industrial and commercial activity needed better cosmopolitan decision-making methods, which in its turn required greater sophistication in the selection, classification, and presentation of information, even more so with the assistance of computers. Taxation and government regulation became more significant and resulted in higher requirement for information; firms had to have available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the demand for bookkeeping for their inner departmental operations went up.

Although bookkeeping processes can be very detailed, all are based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger must have the records of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are prepared from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to display an analysis of any changes that have occurred in the enterprise equity resulting from the transactions of the period. The balance sheet gives the financial position of the company 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 produced 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.
