The typical question heard when looking for a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many business brands and types available, it can be confusing for clients to make a decision between these technologies. It comes down to the fact that LCD projectors have far better image quality and colour accuracy. The following article will explain why DLP projectors struggle with creating a similar level of image quality.

Think of a set of blinds in your home covering your bedroom window. By pulling on a rod you can make the shutters open or closed, according to whether you want to let light in or not. Such is exactly how an LCD projector works. Each pixel works like a single shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the picture reaches your screen is vitally significant for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 separate LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. Something to know about LCD projectors is that all three colours are directed onto your projector screen at the same time. The way a DLP projector runs is widely different and even the produced image looks is not the same. With DLP, white light from the lamp is projected through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image creates a sequence of red, blue and green light. The millions of micro mirrors as mentioned 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 eyes will then pull together each coloured element of the image into a whole image. Using LCD projectors, all colours are available all the time to form top brightness and superb colour accuracy. In DLP, just one colour is available at once, and so causing lower colour brightness and accuracy. Some DLP manufacturers have placed a white segment for the colour wheel to improve all over brightness, but this then damages colour accuracy.

I hear in forums all the time that DLP offers a higher contrast ratio and therefore must be better quality. For those 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 technology is capable of. DLP projectors do possess high contrast specifications as compared to the majority of LCD projectors. At a glance, this must be a benefit, however, in reality, the true black level is determined by the ambient light in the room when the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to see requires moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images keep changing between the time red, blue and green colours are displayed. LCD projectors do not have this problem because every colour is processed at the same time. DLP manufacturers have created 3DLP solutions using 3 chips to fix the colour break up issue, but the expense of these projectors make them impractical for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Remember back to high school science, and recall how various colours of light refract differing amounts when passing through the same lens. The downside with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in different ways. Generally with a DLP projector, some yellow colour will come through above and some extra blue will be projected below an image containing something as simple as a straight black line. In building LCD projectors can be adjusted to reduce these effects on the projected image, as each colour is directed on its own LCD panels.

The sole actual buy point (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to transport and cannot be traded off against the image advantages of LCD projectors. If the outcome of the picture quality is vital to you, then the decision is easy. Go for an LCD projector! LCD projectors will always produce bright, colourful images with fewer image blips.

As the Dutch rose to dominance in sea power during the 17th century, the early yacht had been a pleasure craft used first by royalty and later by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English throne 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 called Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting became popular with the rich and aristocracy, but after that time the trend did not last.

The first yacht club in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, with large naval panoply and rigour. The closest thing to racing boats was the “chase,” for which the “fleet” pursued an imaginary enemy. The club endured, mostly as a social club, until 1765, and in 1828, by joining with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized method on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed 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 setting of British yachting. The society at Cowes became the Royal Yachting Club, also at the rise of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for great bids were held, and the society life was lovely. It came to be that the Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English held power. Sailing was largely for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht group, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The craft of bigger yachts was first largely put upon by the success of America, which was designed by George Steers for a syndicate started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. Earlier yachts were not designed and manufactured in the modern sense, with merely a model used. Not until the second half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what science had previously done for hulls.

Because nearly all sailboats had to be individually built, there was a requirement for handicapping boats as this was previous to the one-design class boats were designed. Thus, a rating rule was written, which resulted in the International Rule, adopted in 1906 and amended 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 the same specifications 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 necessary. A great example is the uniform International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

As long as yachting was done largely for the royal and the rich, money was no problem, and the size of boats grew, in both length and weight. The rise and preference of smaller yachts occurred in the latter half of the 19th century out of 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small yachts. Later in the 20th century, for the larger part after World War II, smaller racing and recreational craft became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, at which point steam began to take the place of sail power in market vessels, the steam engine, and later the internal-combustion engine, were increasingly employed in leisure craft. Large power yachts were developed to a high degree, and long-distance travel was a preferred activity of the rich. The earliest power yachts were paddle-wheel boats; they then made way to those powered by the completely submerged screw or propeller kind of propulsion. As well as naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for many years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts with gasoline or diesel engines.

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

As more sizeable and more dependable internal-combustion engines were created, many big yachts started using them for power. The establishment of the diesel engine, employing heavy oil for fuel, advanced in World War I. From the decade that followed, bigger power-yacht building blossomed, hitting a climax in the Orion (1930) at 3,097 tons. In that time the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of large power yachts lessened in 1932, and the style after that was in preference of smaller, less pricey yachts. Following World War II, many small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a internationally loved competition enjoyed by thousands of yachtsmen who are actually manning and maintaining their own small recreational craft. The amount of yachts and yachtsmen is increasing steadily, not only in the traditional places along the seacoasts 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 a tax that puts the same relative liability on every taxpayer—i.e., in the case where tax liability and income move in the same scale. A progressive tax is recognised by a greater than proportional increase in the tax burden in regard to the growth in income, and a regressive tax is characterized by a less than proportional growth in the comparable burden. Thus, progressive taxes are viewed as removing inequity in income distribution, but regressive taxes might result in increasing these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so within the upper-income demographic—in particular if a taxpayer is allowed to reduce his tax base by nominating deductions or by removing certain income elements from his taxable income. Proportional tax rates which are applied to lower-income categories would also be more progressive if exemptions of a personal nature are made.

Income measured over a given year might not absolutely provide the most suitable measure of taxpaying requirements. For example, transitory growth in income might be saved, and during temporary declines in income a taxpayer might elect to provide for consumption by reducing savings. Thus, if taxation is held in comparison with “permanent income,” it can be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (save those on luxuries) are generally regressive, because the spread of personal income consumed or spent on a specific good declines as the rate of personal income grows. Poll taxes (also called head taxes), nominated as a fixed amount per capita, obviously are regressive.

It is not easy to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant for the most part on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effects of taxation, it is relevant to differentiate between varied concepts of tax rates. The statutory rates are those dictated in the law; generally these are marginal rates, but for some cases they are average rates. Marginal income tax rates denote the fraction of incremental income that is taken by taxation when income grows by one dollar. Thus, if tax liability increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislation generally contain graduated marginal rates—i.e., rates that rise as income grows. Careful analysis of marginal tax rates need to consider provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated within the statutory rates. Since marginal rates signify how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for assessing incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate to apply to income from business and capital, because it may be dependant on factors including 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 zero under a consumption-based tax.

Average income tax rates determine the portion of total income that is taken in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually increase with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households might dampen these effects, allowing regressivity, as indicated by average tax rates that decrease as income grows.

The LCDs put in projection systems are typically small reflective or transmissive panels lit up by a strong arc lamp source. A series of lenses magnifies the reflected or transmitted image and displays it onto a screen. With front-projection systems the LCD is situated on the same side of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of more expense and capacity may be found with three separate LCD panels, forming separate red, green, and blue images that blend to reflect a coloured display on the screen.

The increasing requirement for video 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 possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. In it the liquid crystal molecules are arranged in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are tilted, as shown in the figure. The host liquid crystal has optically active molecules, and a scarcely perceptible turn up of the optical activity and the slant 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 in the plane of the layers. Thus, there exists a permanent charge separation across 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 correct sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been marketed for big passive-matrix presentations, but their high cost and detail has hindered them from making any remarkable movement 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 fast response allows them to be used in time-sequential colour systems, in which dear colour filters are replaced with a coloured backlight that flashes red, green, and blue in fast pace (approximately 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state during the red and green periods and to a nontransmissive state in the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

From each of the furniture needs, the chair may be the paramount one. While many other objects (apart from the bed) are intended to support objects, the chair supports a human form. The term chair can be regarded here in the common sense, from stool to throne to further pieces for example a bench or sofa, which may be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinuishable.

The social history of the chair is as stimulating as its history as art and craft. The chair is not only a physical support and an aesthetic item; it historically was an indicator of social place. From the historical royal courts there were plain connotations between possessing a chair with arms, on a chair with a back but no arms, or worse having to use a stool. From the past century, a director’s and/or manager’s chair has been seen as an indicator of superior dignity, and even in democratic parliaments the speaker sits on a high-set floor.

As its furniture purpose, the chair holds a range of different makes. There are chairs manufactured to fit man’s age and physical capabilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). During past days there were chairs to be born in (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). We have chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has demanded special chairs in automobiles and aircraft. Each and every one of these chair forms have evolved to conform to evolving human needs. Because of its close link with man, the chair comes to its full importance only when in use. Although it makes no difference to one’s appreciation of a cupboard or a chest of drawers if there is anything inside or not, a chair is understood best and tested by a person sitting in it, because chair and sitter require the other. Thus the individual areas of a chair are given labels likened to the areas of the human body: arms, legs, feet, back, and seat.

Because the first role of the chair is to support our human body, its worth is valued generally from how well it fulfills this practical role. In the design of the chair, the carpenter is bound in some static laws and principal measurements. Under these limits, however, the chair creator has large freedom.

The history of the chair extended over an epoch of several thousand years. There is evidence of cultures that had distinctive chair forms, as seen of the highest work in the industries of craft and art. Out of those civilisations, a mention 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of masterful scheme, were known from tomb discoveries. The first one of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs shaped similar to those of some animal, a curved seat, and a sloping back supported with vertical stretchers. In this design a stable triangular form was crafted. There appeared to be no marked variation between the creation of Egyptian thrones and chairs for common citizens. The real change exists in the decorative ornamentation, in the particulars of expensive inlays. The Egyptian folding stool probably was developed to be an easily stored seat for army. As a camp stool this stool continued for much later points. But the stool then also was made as the use of a ceremonial seat, its mechanical role as a folding stool fast forgotten. This can from evidence be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but cannot be folded because the seats were created of wood. The simplistic construction of the folding stool, consisting of two frames that cycle on metal bolts and have a seat of leather or fabric held between them, came again somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this type is the folding stool, made from ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not with any ancient specimen still around but seen in a trove of pictorial items. The better recognised is the klismos depicted on the Hegeso Stele at the Dipylon burial place in outer Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of those legs are visible. These strange legs were presumed to be executed with bent wood and were probably had huge pressure from the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore super durable and were plainly signified.

The Romans borrowed from the Greek chair; designs of models of seated Romans are examples of a thicker and apparently slightly less delicately built klismos. Both features, light and heavy, were revived during the Classicist period. The klismos style is evidenced in French Empire furniture, in English Regency, and in special types of considerable uniqueness of Denmark and Sweden during 1800.

China
The progression of the chair in China can not be traced as well as the history of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed serial of drawings and paintings was protected, showing the interior and outside of Chinese houses and their furniture. Also kept of the 16th century are some chairs constructed from wood or lacquered wood, that display an astonishing resemblance to representations of ancient chairs.

As in Egypt, two fundamental chair forms existed in China: a chair of four legs and a folding stool. That four-legged chair can be designed both with and without arms but never without the square seat and straight stiles (standing side supports) to firm the back. In one design, it must be said, the stiles were lightly curved above the arms to sit correctly with the form of the S-shaped back splat (the main upright of its back). Together, the three parts were mortised on the yoke-like top rail. Despite that the style of a back splat later had an introduction for English chairs of the Queen Anne period, wooden members that could merely to a limited ability stabilise corner joints (and are loose into the bargain) indicate a signature particular to Chinese chairs. The four legs are set through the seat frame, which finishes around the rounded staves. Every member is round in section or is given rounded edges—a left over maybe to the bamboo tradition. The seat is not pleasant and might have had a plaited seat. These chairs needed the sitter to be stiff and upright; if too much weight is placed on the back, the chair has a way of toppling. In patriarchal Chinese homes of this epoch armchairs likely were reserved for elderly family members, for they were given great esteem.

The Chinese folding stool is believed to have travelled to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is delicately affixed to the two legs of the stool with a curved member, which is more often than not provided with metal mounts. From a Western understanding the resulting effect of these furniture forms is stylized. The constructive and decorative issues are combined in a way that is all at once naïve and refined. The piecemeal appearance is a result of the fact that the individual members do not seem to have been put together by either glue or screws, but have been mortised into one another and held 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 name on the chair. Paintings display a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of tiny pads. The front board and a related board from the back could be folded after loosening some tiny iron hooks. Thus the chair was an easily portable piece of furniture for traveling which, at the same time, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be found in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this style of chair is also made in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the innovation actually was instigated in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of slim measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in impressive numbers, as can be seen from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up against a wall. The style asserts itself by virtue of its harmonious proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is, as developed in Paris around 1750—disseminated through most of Europe and was imitated or copied into the mid-20th century. The model owes such popularity to a combination of leisure and charm. The seat suits 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 little upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are constructed from wood of fairly thick density; but all the members are deeply molded, all superfluous wood has been taken away, and more expensive chairs may be further embellished with very delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for the upholstery on the seat, back, and armrests; cane is in some cases used as an alternative to upholstery.

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

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

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

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, 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 creates the numbers from which accounts are made but is a different process, preliminary to accounting.

Fundamentally, bookkeeping grants two types of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking placement in the entity during a single time period.

Management officials, investors, and credit grantors all need this kind of 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 in order to assess the upshot of business operations and make decisions for buying, holding, and selling securities; and credit grantors to regard the financial statements of an enterprise in judging whether to accept a loan.

Pieces of financial and numerical recordkeeping are seen for almost every group of people with a commercial background. Records of trade contracts have been uncovered in the ruins of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The dual-entry method of bookkeeping began with the progression of the entrepeneurial republics of Italy, and tutorial books for bookkeeping were produced during the 15th century in various Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial recordkeeping a must-have. The past of bookkeeping, in fact, closely reflects the history of commerce, industry, and government and, partially, helped to form it. The worldwide market of industrial and commercial activity needed better sophisticate decision-making methodology, which in turn required greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more significant and resulted in higher requirement for information; enterprises 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 become larger, and the need for bookkeeping for their own departmental operations increased.

Though bookkeeping methodology can be extremely detailed, it is all based on two styles of books employed in the bookkeeping procedure—journals and ledgers. A journal has 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.

At the end of every month, generally, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The job of the income statement or profit-and-loss statement is to show an analysis of the changes that have occurred in the enterprise equity resulting from the transactions of the period. The balance sheet provides the financial situation of the entity at a particular point in time with regard to assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

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

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

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