The typical question heard when looking for a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many different brands and models available, it can be challenging for customers to decide between these technologies. It comes down to the fact that LCD projectors offer far better image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with bringing up a comparable standard of image quality.

It’s like a set of blinds in your room on your bedroom window. By a twist of a rod you can make the shutters open or closed, according to if you want to let light in or not. And that is exactly how an LCD projector behaves. Each pixel functions like its own 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 professionals 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 turns on to when the content reaches your screen is ultimately important in 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 transfer the coloured light to 3 separate LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to send the projector image. Something to understad about LCD projectors is that all three colours are sent onto your projector screen at the same time. The way a DLP projector functions is vastly different and even the produced image looks 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 way of making an image requires a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eye will then draw each coloured element of the image into the single whole image. In LCD projectors, all colours are available all the time to offer top brightness and spectacular colour accuracy. In DLP, just one colour is available at any given time, and so causing lower colour brightness and accuracy. Some designers have added a white segment for the colour wheel to improve brightness generally, but this further lessens colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and ergo must be superior. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of. DLP projectors do possess high contrast specifications in comparison to most LCD projectors. At one glance, this must be an advantage, however, in real life, the true black level is determined by the ambient light in the room in which the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to project needs moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible 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 characteristic because every colour is projected at once. DLP developers have formed 3DLP solutions using 3 chips to fix the colour break up artifacts, but the expense of these projectors make them not practical for many businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Remember back to high school science, and recall when they taught you how the different colours of light refract varied amounts when passing through the same lens. The downside with DLP projectors is that they utilise the one same panel with the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Often with a DLP projector, a superfluous yellow colour will come up above and a spill of blue will show below an image of something as simple as a lone black line. In manufacturing LCD projectors can be adapted to remove these effects on the projected image, as each colour is processed on isolated LCD panels.

The one true benefit (excluding price) with picking a DLP projector is its smaller total size and weight. However, this is only relevant in regard to transport and needs to be traded off against the image advantages of LCD projectors. If overall picture quality is crucial to you, then the answer is easy. Take an LCD projector! LCD projectors will consistently create bright, colourful images with fewer image blips.

As the Dutch rose to preeminence in sea power during the 17th century, the initial yacht had been a pleasure craft used initially by royalty and secondly by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, borne from private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting became classy for the affluent and aristocracy, but after that period the habit did not last.

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

Yacht racing began in some stipulated 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 came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, 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 funding made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British yachting. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing races for great bets were held, and the society life was superlative. 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 went on when the English took dominance. Sailing was for the most part for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a benchmark of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through to the latter half of the 19th century. The design of bigger yachts was originally greatly affected 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.) had its namesake after its victory at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with merely a model for an outline. Not until the latter half of the 19th century did what was labeled naval architecture come about. 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 almost all sailboats had to be individually built, there was a requirement for handicapping boats before the one-design class boats were designed. Thus, a rating rule came into being, which resulted in the International Rule, accepted in 1906 and edited in 1919. In modern times, one of the rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even par with no handicapping required. A great example is the generic International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

For the time that yachting belonged primarily for the nobility and the affluent, cost was no issue, and the size of boats grew, in both length and weight. The rise and popularity of smaller craft came in the second 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 voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of less sizeable boats. Later in the 20th century, notably after World War II, smaller racing and leisure boats became more common, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam was set to take the place of sail power in public vessels, the steam engine, and later the internal-combustion engine, were employed more and more in pleasure vessels. Large power yachts were developed to a high standard, and long-distance cruising was a fond activity of the affluent. The earliest power yachts were paddle-wheel boats; they then gave way to boats powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a push in the manufacture of bigger steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service in World War II.

As bigger and more dependable internal-combustion engines were developed, many big yachts began using them for power. The establishment of the diesel engine, employing heavy oil for fuel, was furthered for World War I. During the decade after that, big power-yacht building flourished, reaching 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 large power boats declined from 1932, and the style from then was toward smaller, less pricey boats. Following World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally loved sport enjoyed by thousands of yachtsmen individually owning and keeping their own small pleasure yachts. The number of craft and owners is increasing steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is a tax that impinges the same relative onus on each taxpayer—i.e., when tax liability and income grow in the same proportion. A progressive tax is recognisable by a higher than proportional growth in the tax liability relative to the growth in income, and a regressive tax is characterized by a less than proportional increase in the comparable burden. Thus, progressive taxes are regarded as removing a lack of equality in income distribution, while regressive taxes are found to cause an increase in these inequalities.

The taxes that are generally believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so for the upper-income group—especially if a taxpayer is allowed to reduce his tax base by nominating deductions or by taking some income components from his taxable income. Proportional tax rates when applied to lower-income demographics can also be more progressive if exemptions of a personal nature are declared.

Income measured over the course of a given year may not necessarily offer the most suitable measure of taxpaying requirement. For example, transitory growth in income might be saved, and in temporary declines in income a taxpayer may opt to provide for consumption by decreasing savings. Thus, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (save on luxuries) are generally regressive, because the spread of individual income consumed or spent for a specific good lowers as the rate of personal income grows. Poll taxes (also known as head taxes), nominated as a standard amount per capita, patently are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to uncertainty 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 for the most part on whether a national or a subnational (that is, provincial or state) tax is being debated.

In regarding the economic effects of taxation, it is necessary to distinguish between several points of tax rates. The statutory rates will include those dictated in the legislation; often these are marginal rates, but sometimes they are median rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income grows by one dollar. Thus, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that increase as income grows. Heavy analysis of marginal tax rates should review 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 growth in income, the marginal rate is 20 percentage points greater than nominated by the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, because it may be dependant on such factors 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 nil under a consumption-based tax.

Average income tax rates signify the portion of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates usually increase with income, both because personal allowances are allowed 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 might dampen these effects, forcing regressivity, as displayed by average tax rates that fall as income increases.

The LCDs utilised in projection systems are generally small reflective or transmissive panels lit up by a bright arc lamp source. A line of lenses enlarges the reflected or transmitted image and displays it on the screen. With front-projection systems the LCD is located on the side of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of higher cost and capability sometimes be found with three distinct LCD panels, creating separate red, green, and blue images that come together to make a coloured display on the screen.

The increasing need for pictographic displays has granted a particular emphasis on the switching speed of liquid crystals. This has demanded the manufacture of devices utilizing smectic liquid crystals, some kinds of which emit a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. In it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are on a slant, as displayed in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible turn up of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous 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 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 or when one or more polarizers are used.

SSFLC devices have been commercialized for bigger passive-matrix presentations, but their high cost and complex detail has impeded them from enjoying any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be made use of in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast pulsing (approx 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state in the red and green periods then to a nontransmissive state during the blue period, with the result that the eye sees an average of red and green light, or the colour yellow.

Of all furniture forms, the chair could be the most imperative. While the majority of other objects (save the bed) are intended to support objects, the chair supports the human form. The term chair can be regarded here in the larger sense, from stool to throne to complex chairs including the bench or sofa, which might be looked upon 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 exciting as its history as an art and craft. The chair is not only a physical support or an aesthetic piece of art; it historically was an indicator of social place. In the historical royal courts there were clear differences between being seated on a chair with arms, on a chair with a back but without arms, or having to squat on a stool. In the past century, a director’s and manager’s chair has been an indicator of superior status, as well as in democratic governments the speaker sits on a high-set level.

In its furniture creation, the chair can be employed for a number of various models. There are chairs designed to suit man’s age and physical abilities (the high chair, the wheelchair) and to show his standing in society (the executive chair, the throne). From the past there were chairs used for birthing (birth chairs); from the 20th century, there have been chairs used to die in (the electric chair). We design chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern living has derived particular chairs for automobiles and aircraft. All these chair types has been changed to match to growing human requirements. From its significant association with man, the chair exists to its full purpose only when utilised. Whereas it isn’t relevant to one’s appreciation of a cupboard or a set of drawers if there are items inside or not, a chair is really seen best and fairly regarded by a person using it, because chair and sitter complement each other. Thus the individual areas of the chair have been labeled corresponding to the parts of the human parts: arms, legs, feet, back, and seat.

Because the primary work of the chair is to support a human body, its credit is valued firstly from how fully it does fulfill this practical purpose. In the structure of the chair, the builder is bound by the static legislation and principal measurements. Inside these rules, however, the chair builder has marvellous freedom.

The history of the chair extends over an epoch of several thousand years. There are societies that had significant chair forms, seen of the highest endeavour in the spheres of handling and design. In such cultures, individual note should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of skilled make, are now known from tomb discoveries. One of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs formed not unlike those of a particular animal, a curved seat, with a sloping back supported above vertical stretchers. In this design a durable triangular design was created. There appeared to be no particular variation in the structure of Egyptian thrones and chairs for ordinary non-royals. The real change existed in the kind of ornamentation, in the selection of more costly inlays. The Egyptian folding stool likely was crafted for an easily packed seat for officers. As a camp stool the type persevered until much later periods. But the stool also then was made as the task of a ceremonial seat, its original task as a folding stool neglected or forgotten. This can now be seen, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but are not able to be folded because the seats were formed with wood. The easy structure of the folding stool, composed of two frames that cycle on metal bolts and have a seat of leather or fabric held between them, reappears but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this kind is the folding stool, made out of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is recognised not with any ancient fossil still extant but found in a variety of pictorial items. The iconic kind is the klismos displayed on the Hegeso Stele at the Dipylon burial ground by Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of which can be displayed. These curving legs were understood to be created with bent wood and were as such bore a large amount of pressure with the weight of the sitter. The joints joining the legs to the frame of the seat had to be therefore very durable and were clearly denoted.

The Romans borrowed from the Greek chair; existing statues of seated Romans display examples of a denser and are a rather more crudely constructed klismos. Both styles, the light and the heavy, were brought back as part of the Classicist time. The klismos style can be seen in French Empire design, in English Regency, and in some particular kinds of notable uniqueness in Denmark and Sweden circa 1800.

China
The progression of the chair in China cannot be tracked as long as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed series of drawings and paintings had been protected, showing the interiors and exteriors of Chinese households and the designs of furniture. Another preservation since the 16th century are a trove of chairs of wood or lacquered wood, that display an astonishing likeness to designs of previous chairs.

Just the same as in Egypt, there were two iconic chair forms in China: a chair with four legs and a folding stool. The four-legged chair has been designed both with and without arms but always having the square seat and straight stiles (upright side supports) to give support to the back. In one type, it has been seen, the stiles had been marginally curved on top of the arms to sit right with the form of the S-shaped back splat (the central upright of a back). Together, all three sections were mortised into the yoke-like top rail. Though the innovation of the Chinese back splat later had an influence on English chairs of the Queen Anne period, wooden items that merely to a restricted limit stabilise corner joints (and furthermore are loose to top it off) indicate an element solely to Chinese chairs. The four legs pass through the seat frame, which ends about the rounded staves. All members are round in section or has rounded edges—a left over as may be to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited form. These chairs required the sitter to remain stiff and upright; for when too much weight is placed on the back, the chair has a way of falling over. In patriarchal Chinese homes of this period armchairs most likely were allowed only for senior members of the family, for they were held in great respect.

The Chinese folding stool is believed to have travelled to China from the West. It does not differ so very much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is prettily held to the two legs of the stool by means of a curved member, which is usually seen with metal mounts. From a Western point of view the ultimate effect of both furniture designs is stylized. The construction and aesthetic aspects are combined in a way that is simultaneously naïve and refined. The piecemeal appearance is a result of the way that the individual parts do not appear to have been adjoined by means of either glue or screws, but have been mortised on one another and held in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Works of art display a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in between the layers, stitched to show up a pattern of small pads. The front board and a corresponding board from the back could be folded after unscrewing some tiny iron hooks. Therefore the chair was an easily portable piece of furniture for traveling which, during the same time, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is seen in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair might also be found in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not determined that the style actually started in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was crafted in considerable quantities, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up by a wall. The style asserts itself by virtue of its elegant proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that is, as developed in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The chair owes the popularity to a combination of relaxation and delicacy. The seat adheres 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 small upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are strongly constructed on craftsmanlike principles in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of fairly thick measurements; but each member is deeply molded, all extraneous wood has been removed, and finer items would be further embellished with intricately delicate and decorative carvings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all of the upholstery on the seat, back, and armrests; cane is sometimes used rather than upholstery.

English chairs of the 18th century were more open in style than the French. The French touch for stylistic uniformity, which spread from the premier circles in Paris and Versailles within most of France and was popularised 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
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, 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 figures from which accounts are made but is a separate process, prerequisite to accounting.

Basically, bookkeeping finds two parts of information: (1) the current value, or equity, of the business and (2) changes in value—profit or loss—taking place in the entity from a given period.

Management officials, investors, and credit grantors all have to have this information: management in order to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to assess the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an entity in judging whether to grant a loan.

Bits and pieces of financial and numerical charts are seen for just about every society with a commercial history. Records of business contracts have been discovered in the archaelogical digs of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The double-entry way of bookkeeping started with the furthering of the business republics of Italy, and manuals for bookkeeping were created in the 15th century in several Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a requirement. The ancestry of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, in part, assisted to shape it. The worldwide movement of industrial and commercial activity required more sophisticate decision-making methodology, which then demanded more sophistication in the selection, classification, and presentation of information, even more so with the assistance of computers. Taxation and government legislation became more important and resulted in increased requirement for information; business entities 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 become larger, and the demand for bookkeeping for their inner departmental operations became higher.

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

At the end of every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to provide an analysis of those changes that have occurred in the enterprise equity because of the events of the period. The balance sheet displays the financial situation of the enterprise at any particular point regarding 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.
