The most typical question customers ask when buying 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, which stands for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many different brands and models available, it can be challenging for the buyer to make a decision between these technologies. It comes down to the fact that LCD projectors provide far better image quality and colour accuracy. The article below will tell you why DLP projectors struggle with bringing up a comparable grade of image quality.

It’s like a set of blinds in your home on your bedroom window. By pulling on a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. This is exactly how an LCD projector behaves. Each pixel operates like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the image reaches your screen is absolutely important with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then meshed in a glass prism to create the projector image. An important point to understad about LCD projectors is that all three colours are sent onto your projected surface simultaneously. The way a DLP projector runs is vastly different and even how an image looks is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image creates a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to construct 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 combine each coloured element of the image into a single whole image. In LCD projectors, all colours are available all the time to form the best brightness and great colour accuracy. In DLP, just one colour is available at once, and so causing lower colour brightness and accuracy. Some developers have added a white segment in the colour wheel to improve general brightness, but this also damages colour accuracy.

I read in forums all the time that DLP offers a higher contrast ratio and ergo must be better. For those who are unaware, 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 system is capable of producing. DLP projectors do possess high contrast specifications as compared to the majority of LCD projectors. At first glance, this must be a benefit, however, in real life, the true black level is determined by the ambient light in the room while the projector is used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you want to view includes moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most common artifact that a DLP projector creates with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are shone. LCD projectors do not have this disadvantage because the colours are projected at once. DLP developers have formed 3DLP solutions using 3 chips to answer the colour break up problem, but the cost of these projectors make them almost impossible for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how the different colours of light refract different amounts when shone through the same lens. The problem with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Most of the time with a DLP projector, an extra yellow colour will come through above and an extra blue will be projected below an image containing something as simple as a lone black line. While being built LCD projectors can be adjusted to take away these effects on the projected image, as each colour is directed on a separate LCD panels.

The only real buy point (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transport and cannot be traded off against the image benefits of LCD projectors. If the result of the picture quality is important to you, then the choice is a no-brainer. Take an LCD projector! LCD projectors will consistently produce bright, colourful images with fewer image errors.

As the Dutch came to preeminence in sea power during the 17th century, the first yacht was a leisure craft used mostly by royalty and later by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private challenges. English yachting began with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting rose as classy with the affluent and nobility, but after that period the fashion did not last.

The first yacht group in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had much naval panoply and gravity. The closest thing to racing was the “chase,” when the “fleet” pursued an imagined enemy. The club endured, largely as a social club, until 1765, and in 1828, when merging with other clubs, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to the throne in 1820, it was called 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 organisation had been initiated at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British yacht racing. The organisation at Cowes became the Royal Yachting Club, again at the rise of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the social life was lovely. It came to be that the Royal Yachting Club boats were raised in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English took dominance. Sailing was for the most part for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a standard of luxury and sophistication for the later yachts in the area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of bigger yachts was initially largely put upon by the win 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 crafted in today’s 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 use of the study of aerodynamics do for the craft of sails and rigging what it had earlier done for hulls.

Because most of all sailboats had been individually built, there came a desire for handicapping boats as this was before the one-design class boats were built. Therefore, a rating rule was decreed, which ended up in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the fastest flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to standard requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between such boats can be held on an even par with no handicapping required. A great example is the uniform International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

As long as yachting was an activity largely for the nobility and the rich, expense was no object, and the size of boats increased, in both length and weight. The ascendancy and preference of smaller yachts came in the later half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of small boats. Later in the 20th century, notably after World War II, smaller racing and recreational yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, during which steam started to emulate sail power in public vessels, the steam engine, and later the internal-combustion engine, were employed increasingly in personal yachts. Sizeable power yachts were developed to a high degree, and long-distance sailing became a favoured pastime of the rich. The first power yachts were paddle-wheel boats; those then made way to boats powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant craft, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the construction of bigger steam yachts. Notably within these was the Mayflower (1897) of 2,690 tons, containing 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 gave active service during World War II.

As larger and better quality internal-combustion engines were created, many large craft started using them for power. The creation of the diesel engine, employing heavy oil for fuel, was furthered from World War I. During the decade after, large power-yacht building grew, hitting a climax in the Orion (1930) at 3,097 tons. During that point the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power yachts lessened from 1932, and the trend from then was toward smaller, less expensive boats. From World War II, a lot of small naval boats were sold to private owners for conversion to yachts. At the late 20th century, yachting has become a internationally popular activity enjoyed by thousands of yachtsmen personally owning and keeping their own small leisure yachts. The number of yachts and yachtsmen increased steadily, not only in the traditional places along the beach but also on inland waterways and lakes.

Taxes can be categorized by the effect they have on the allocation of income and wealth. A proportional tax is the kind that puts the same relative liability on each taxpayer—i.e., in the case where tax liability and income grow in relative levels. A progressive tax is recognised by a larger than proportional growth in the tax burden in regard to the growth in income, and a regressive tax is recognisable by a less than proportional growth in the comparative burden. So, progressive taxes are regarded as fighting inequalities in income distribution, but regressive taxes are believed to have the result of an increase in these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so within the upper-income categories—especially if a taxpayer is permitted to lessen his tax base by nominating deductions or by leaving out certain income aspects from his taxable income. Proportional tax rates if applied to lower-income demographics will also be more progressive if personal exemptions are declared.

Income measured over the period of a given year does not necessarily give the most accurate measure of taxpaying ability. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer might elect to finance consumption by decreasing savings. Thus, if taxation is made comparable along with “permanent income,” it will be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are usually regressive, because the dissemination of individual income consumed or spent for specific goods declines as the rate of personal income increases. Poll taxes (aka head taxes), nominated as a set amount per capita, clearly are regressive.

It is difficult to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, 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 crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effect of taxation, it is necessary to differentiate between various ideas of tax rates. The statutory rates will be specified in the legislation; generally these are marginal rates, but sometimes they are average rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income rises by one dollar. So, if tax burden increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislation usually contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates are required to consider provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than indicated within the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for assessing incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applied to income from business and capital, because it may be dependant on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates display the fraction of total income that is required in taxation. The pattern of average rates is the one that is necessary for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households may swamp these effects, producing regressivity, as displayed by average tax rates that lower as income increases.

The LCDs utilised for projection systems are usually small reflective or transmissive panels illuminated by a forceful arc lamp source. A line of lenses expands the reflected or transmitted image and then sends it onto a screen. With front-projection systems the LCD is placed on the same side of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of higher expense and capability sometimes have three separated LCD panels, reflecting separate red, green, and blue images that combine to reflect a coloured picture on the screen.

The growing need for film displays has had a special emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items utilizing smectic liquid crystals, particular types of which give a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most sophisticated smectic device. With it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a slight outcome of the optical activity and the shape of the molecules is the presence 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 in the plane of the layers. Hence, there is a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark if one or more polarizers are used.

SSFLC devices have been commercialized for larger passive-matrix displays, but their expense and complexity has prevented them from creating any great progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as elements in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be utilised in time-sequential colour systems, in which expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick succession (approx 100 cycles in a second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and to a nontransmissive state for the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

From all the furniture forms, the chair might be the imperative one. While the majority of other items (except the bed) are devised to support objects, the chair supports our human form. The term chair should be used here in the widest sense, from stool to throne to complex items for example a bench and sofa, which should be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently defined.

The social history of the chair is as exciting as its history as art and craft. The chair is not simply a physical support and aesthetic craft; it can also be an indicator of social standing. Within the Medieval royal courts there were clear connotations between being led to a chair with arms, sitting on a chair with a back but without arms, and having to sit on a stool. From the 20th century, a director’s or manager’s chair has developed an identifier of superior position, and in democratic government meeting the speaker sits on an elevated platform.

As its furniture creation, the chair can be utilised for a range of different purposes. There are chairs created to match man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his status in society (the executive chair, the throne). During the olden days there were chairs used for birth (birth chairs); in the 20th century, there have been chairs used 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 have chairs that can be folded, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated particular chairs for use in automobiles and aircraft. Each of these chair shapes have been evolved to suit to evolving human desires. For its significant importance with man, the chair appears to its full purpose only when being utilised. Though it isn’t relevant to one’s appreciation of a cupboard or a bureau whether there might be anything inside or not, a chair is really seen and evaluated with a person sitting on it, because chair and sitter require the other. Thus the various elements of the chair were named like the elements of a human shape: arms, legs, feet, back, and seat.

Because the principal role of a chair is to support the body, its worth is valued basically by how completely it does fulfill this practical function. In the manufacture of a chair, the maker is bound under particular static regulations and principal measurements. Within these regulations, however, the chair builder has extensive freedom.

The history of the chair covers a period of several thousand years. There were societies that had iconic chair shapes, as seen of the premier endeavour in the industries of skill and art. Within such peoples, individual note 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 construct of careful design, were found from tomb findings. One of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs shaped as akin to those of a particular animal, a curved seat, leading to a sloping back supported over vertical stretchers. In this design a strong triangular structure was created. There was in our view no noteworthy variation in the structure of Egyptian thrones and chairs for regular people. The only change lied in the intricacy of its ornamentation, in the selection of expensive inlays. The Egyptian folding stool most likely was developed to be an easily portable seat for army soldiers. As a camp stool this chair existed for much later points. But the stool then also was designed for the purpose of a ceremonial seat, its original function as a folding stool neglected or forgotten. This can now be observed, 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 are in the construction of folding stools but are not able to be folded as the seats were made with wood. The simplistic construction of the folding stool, consisting of two frames that rotate on metal bolts and have a seat of leather or fabric set between them, appeared again at some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this type is the folding stool, of ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not as any ancient object still extant but as in a large amount of pictorial evidence. The best recognised is the klismos drawn on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of these legs could be seen. These unique legs were most likely created in bent wood and were therefore subjected to a large amount of pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat would have had to be therefore super durable and were overtly drawn.

The Romans adopted the Greek designs; evidence of statues of seated Romans are evidence of a more heavyset and are a slightly less intricately constructed klismos. Both styles, the light or heavy, were brought back as part of the Classicist epoch. The klismos style is used in French Empire furniture, in English Regency, and in special types of marked iconicism of Denmark and Sweden during 1800.

China
The ancestry of the chair in China is not able to be tracked as well as chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken collection of drawings and works of art was kept safe, displaying the interiors and outer parts of Chinese households and the kinds of furniture. Kept also since the 16th century are a trove of chairs made from wood or lacquered wood, that display an astonishing familiarity to pictures of previous chairs.

Just like in Egypt, there were two particular chair forms in China: a chair having four legs and a folding stool. That four-legged chair was seen both with and without arms though never without the square seat and straight stiles (standing side supports) to give support to the back. In one image, it has been seen, the stiles could be lightly curved over the arms in order to fit the structure of the S-shaped back splat (the basic upright of its back). The three sections had been mortised onto the yoke-like top rail. Despite that the style of a back splat exercised an inspiration for English chairs of the Queen Anne period, wooden items that would merely to a limited ability reinforce corner joints (and furthermore were loose additionally) indicate an element particular to Chinese chairs. The four legs are set through the seat frame, which ends upon the rounded staves. Each member is round in section or is given rounded edges—referable as may be to the bamboo tradition. The seat is not comfortable and had on occasion a plaited seat. These chairs required of the sitter to stay stiff and upright; for when too much weight is exerted on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this epoch armchairs presumably were reserved only for older family members, for they were held in great esteem.

The Chinese folding stool is understood to have come to China from the West. It does not vary much from the Egyptian or Scandinavian folding stools, but it possesses a difference in that the top rail is intricately affixed to the two legs of the stool by using a curved member, which is often possessing metal mounts. From a Western point of view the resulting effect of both these furniture styles is stylized. The manufacture and decoration elements are combined in a manner that is all at once both naïve and refined. The pieced-together appearance is an outcome of the manner that the individual members do not appear to have been fixed together with either glue or screws, but were mortised on one another and locked into place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its name on the chair. Works of art show a type of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in between the layers, stitched to bring out a pattern of tiny pads. The front board and a corresponding board in the back could be folded after unscrewing some little iron hooks. In this way the chair was an easily portable piece of furniture for traveling which, during the same time, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be evidenced 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. While this type of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not certain that the innovation actually was instigated in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slender measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was manufactured in impressive amounts, as can be seen from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up against a wall. The design asserts itself with its harmonious 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 is to say, as created in Paris around 1750—disseminated over most of Europe and was imitated or copied during the mid-20th century. The chair owes this popularity to a combination of leisure and delicacy. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are tiny upholstered pads on the armrests. Smooth transitions are found between seat frame, legs, and back disguise all the joints, which are constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of fairly thick measurements; but all the members are deeply molded, all extra wood has been taken away, and finer chairs may be further embellished with highly delicate and decorative engraving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all the upholstery on the seat, back, and armrests; cane is sometimes used instead of upholstery.

English chairs from the 18th century were more open in design than the French. The French taste for stylistic uniformity, which spread from the aristocratic circles in Paris and Versailles through most of France and won 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 popular and was widely distributed throughout the world.

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

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

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

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping gives the details from which accounts are written but is a different process, required prior to accounting.

Basically, bookkeeping provides two areas 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 within a particular period.

Management officials, investors, and credit grantors all need this information: management in order to analyse the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to analyse the upshots of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to regard the financial statements of an enterprise in judging whether to give a loan.

Bits and pieces of financial and numerical charts are found for nearly every state with a commercial history. Records of commercial contracts were uncovered in the archaelogy of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The dual-entry method of bookkeeping started with the furthering of the commercial republics of Italy, and tutorial books for bookkeeping were produced in the 15th century in many Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial records a must-have. The ancestry of bookkeeping, in fact, closely reflects the history of commerce, industry, and government and, in part, assisted to form it. The global expansion of industrial and commercial activity required higher cosmopolitan decision-making procedures, which then required higher sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government legislation became more detailed and resulted in higher requirement for information; entities had to show available information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for their inner departmental operations went up.

While bookkeeping procedures can be extremely multifaceted, it is all based on two styles of books utilised in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger contains the details of individual accounts. The daily records kept in the journals are written in the ledgers.

Every month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted out of the ledger. The duty of the income statement or profit-and-loss statement is to display an analysis of any changes that have occurred in the ownership equity because of the events of the period. The balance sheet displays the financial condition of the corporation at any particular day taken from assets, liabilities, and the ownership equity.

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields resulted in an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.
