The common question customers ask when looking for a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many brands and different types available, it can be confusing for the buyer to make a decision between those technologies. The fact is that LCD projectors provide far better image quality and colour accuracy. The next paragraph will explain why DLP projectors struggle with projecting an equal grade of image quality.

It’s like a set of blinds in your household on your bedroom window. With the twist of a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. And this is exactly how an LCD projector functions. Each pixel works like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector is turned on to when the picture reaches your screen is vitally important for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by dividing it into red, blue and green components, by three mirrors which project the coloured light to 3 individual LCD panels. The 3 LCD panels form the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. A significant point to realise about LCD projectors is that all three colours are delivered onto your screen all at the same time. The way a DLP projector functions is widely different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is sent through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming 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 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 put together each coloured element of the image into the single whole image. From LCD projectors, all colours are available all the time to offer high brightness and great colour accuracy. In DLP, just one colour is available at a time, and so causing lower colour brightness and accuracy. Some developers have included a white segment for the colour wheel to improve brightness generally, but this then detracts from colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and as such must be better. For those 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 machine is capable of. DLP projectors do offer high contrast specifications in comparison to the majority of LCD projectors. At a glance, this must be a benefit, however, in the real world, the true black level is determined by the ambient light in the room when the projector is used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to project requires moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most typical artifact that a DLP projector displays with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are projected. LCD projectors do not have this disadvantage because all colours are delivered simultaneously. DLP designers have developed 3DLP solutions using 3 chips to solve the colour break up problem, but the cost of these projectors make them not practical for most businesses and consumers.

Another difference between LCD and DLP is how they balance for the refractive qualities of light. Remember back to high school science, and remember how various colours of light refract different amounts when directed through the same lens. The downfall with DLP projectors is that they take the one same panel for 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, an extra yellow colour will show above and some blue will come up below an image of something as simple as a straight black line. In building LCD projectors can be fixed to minimize these effects on the projected image, as each colour is processed on separate LCD panels.

The one real plus (excluding price) with picking a DLP projector is its smaller size and weight. However, this is only relevant to transporting the device and needs to be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is crucial to you, then the choice is easy. Choose an LCD projector! LCD projectors will always produce bright, colourful images with fewer image mistakes.

As the Dutch rose to dominance in sea power during the 17th century, the initial yacht had been a pleasure craft used first by royalty and later by the burghers in the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private matches. 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 presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting became fashionable for the wealthy and royalty, but after that point the fashion did not last.

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

Yacht racing began in some organized manner on the Thames in the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy 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 association had been started 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 yacht racing. The society at Cowes became the Royal Yachting Club, also at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the social life was splendid. Eventually Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was mostly for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a benchmark of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of large yachts was originally largely put upon by the success of America, which was drawn by George Steers for a group headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its win at Cowes in 1851. The first yachts were not designed and manufactured in the modern sense, with only a model for an outline. Not until the second half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the use of the science of aerodynamics do for the design of sails and rigging what it had done earlier for hulls.

Because nearly all sailboats were individually manufactured, there was a need for handicapping boats before the one-design class boats were designed. Thus, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and amended in 1919. In the present day, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to the same requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing those boats can be done on an even par with no handicapping necessary. A great example is the generic International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting was done largely for the aristocracy and the wealthy, money was no object, and the size of boats developed, in both length and weight. The rise and preference of smaller craft came in the second half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of small yachts. Later in the 20th century, particularly after World War II, smaller racing and recreational yachts became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats 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 was set to emulate sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure vessels. Sizeable power yachts were furthered to a high degree, and long-distance travel became a fond pastime of the well off. The earliest power yachts were paddle-wheel boats; these then gave way to boats powered by the completely submerged screw or propeller sort of propulsion. Like naval and merchant vessels, auxiliaries with both sail and power were the yacht fashion for a number of years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a boom in the manufacture of more sizeable steam yachts. In particular within these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of more than 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 saw active service during World War II.

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

The building of larger power yachts lessened after 1932, and the style thereafter was toward smaller, less costly boats. From World War II, many small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally popular sport enjoyed by thousands of yachtsmen individually sailing and upkeeping their own small recreational boats. The popularity of yachts and sailors increased steadily, not only in the traditional locations along the seacoasts 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 the kind of tax that applies the same relative liability on each taxpayer—i.e., where tax liability and income move in the same proportion. A progressive tax is characterizable by a greater than proportional growth in the tax liability relative to the growth in income, and a regressive tax is recognised by a less than proportional growth in the related liability. So, progressive taxes are seen as fighting the lack of equality in income distribution, while regressive taxes are believed to have the result of increasing these inequalities.

The taxes that are generally regarded as progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, could become less so for the upper-income class—especially if a taxpayer is able to lessen his tax base by nominating deductions or by taking some income components from his taxable income. Proportional tax rates when applied to lower-income categories can also be more progressive if personal exemptions are made.

Income measured over the course of a given year does not necessarily give the best measure of taxpaying status. For example, transitory rises in income might be saved, and in temporary declines in income a taxpayer might choose to finance consumption by decreasing savings. Therefore, if taxation is made comparable with “permanent income,” it would be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (with the exception of those on luxuries) are generally regressive, because the spread of own income consumed or spent for specific goods declines as the level of personal income grows. Poll taxes (aka head taxes), calculated as a flat amount per capita, clearly are regressive.

It is complicated to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic purposes of taxation, it is necessary to differentiate between several concepts of tax rates. The statutory rates will include those nominated in law; generally speaking these are marginal rates, but in some cases they are median rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income rises by one dollar. Hence, if tax burden increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes often contain graduated marginal rates—i.e., rates that grow as income rises. Structured 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) falls by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than indicated in the statutory rates. Since marginal rates signify how after-tax income moves in response to changes in before-tax income, they are the important ones for regarding incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate applicable to income from business and capital, as it may be dependant on considerations 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 nil under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is in consideration for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally rise with income, both because personal allowances are permitted 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 could swamp these effects, forcing regressivity, as shown by average tax rates that decline as income grows.

The LCDs used in projection systems are typically small reflective or transmissive panels illuminated by a forceful arc lamp source. A number of lenses magnifies the reflected or transmitted image and sends it on the screen. For front-projection systems the LCD is placed on the same side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of more expense and performance might use three separated LCD panels, creating separate red, green, and blue images that mesh to form a coloured image on the screen.

The growth in demand for pictographic presentations has placed a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of objects using smectic liquid crystals, particular types of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most sophisticated smectic device. In it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are tilted, as displayed in the figure. The host liquid crystal holds optically active molecules, and a slight consequence 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 in the plane of the layers. So, there must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly coupled 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 by doing so reverse the tilt direction of the molecules. The respective 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 displays, but their high cost and detail has hindered them from enjoying any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate response allows them to be employed in time-sequential colour systems, in which costly colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pace (around 100 cycles a second). For example, the liquid crystal might be switched to a transmissive state in the red and green periods but to a nontransmissive state during the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

Out of each of the furniture pieces, the chair might be the imperative one. While most of the other pieces (apart from the bed) are meant to support objects, the chair supports your human form. The term chair is used here in the most common sense, from stool to throne to further forms including the bench or sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinguished.

The social history of the chair is as curious as its history as an art and craft. The chair is not just a physical support and aesthetic craft; it historically was an indicator of social hierarchy. At the Medieval royal courts there were social signifiers between possessing a chair with arms, sitting on a chair with a back but without arms, and having to use a stool. In the recent century, the director’s and/or manager’s chair has been regarded as an indicator of superior position, as well as in democratic governments the speaker sits on a higher platform.

In its furniture creation, the chair can be utilised for a number of various models. There are chairs structured to match man’s age and physical abilities (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). From historical times there were chairs to be born in (birth chairs); since the 20th century, there have been chairs for ending life (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. We can have chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has demanded special chairs for automobiles and aircraft. Each and every one of these chair kinds has changed to conform to differing human desires. From its particular connection with man, the chair exists to its full purpose only when utilised. Though it does not make any difference to one’s appreciation of a cupboard or a bureau if there might be items inside or not, a chair is understood best and evaluated with a person sitting in it, because chair and sitter complement the other. Thus the individual elements of the chair have been named according to the limbs of the human body: arms, legs, feet, back, and seat.

Because the elemental role of the chair is to support our human body, its credit is tested basically by how well it does fulfill this practical role. Within the construction of the chair, the maker is restricted in certain static regulation and principal measurements. Within these limitations, however, the chair maker has awesome freedom.

The history of the chair was an era of several thousand years. There are societies that had unique chair shapes, expressive of the foremost work in the areas of craft and aesthetics. Within these such societies, particular note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of expert craft, are a finding from tomb findings. The first of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs shaped as akin to those of a particular animal, a curved seat, and with a sloping back supported above vertical stretchers. From this design a strong triangular structure was made. There was to our understanding no notable difference in the structure of Egyptian thrones and chairs for regular non-royals. The main difference exists in the complexity of ornamentation, in the choice of more valuable inlays. The Egyptian folding stool in all probability was crafted for an easily stored seat for soldiers. As a camp stool this type stayed around for much later times. But the stool also then was created as the task of a ceremonial seat, its original job as a folding stool ignored or forgotten. This can now be observed, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but cannot be folded because the seats are made from wood. The simple manufacture of the folding stool, composed of two frames that cycle on metal bolts and hold a seat of leather or fabric secured between them, was then seen at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of those is the folding stool, made out of ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not from any ancient specimen still existing but from a variety of pictorial evidence. The significant kind is the klismos posited on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those can be seen. These unique legs were presumed to be manufactured of bent wood and were probably subjected to extreme pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat were therefore super durable and were plainly denoted.

The Romans borrowed from the Greek style; some models of seated Romans display evidence of a more heavyset and are a rather crudely constructed klismos. Both designs, the light and heavy, were seen again as part of the Classicist era. The klismos influence is seen in French Empire chairs, in English Regency, and in some kinds of considerable iconicism of Denmark and Sweden from 1800.

China
The past of the chair in China is not able to be tracked as far as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) a full series of drawings and paintings was kept safe, detailing the insides and exteriors of Chinese homes and their furniture. Also kept since the 16th century are some chairs of wood or lacquered wood, that show an astonishing similarity to images of past chairs.

As was the case in Egypt, two fundamental chair forms existed in China: a chair of four legs and a folding stool. This four-legged chair can be designed both with and without arms however always with its square seat and straight stiles (straight side supports) to firm the back. In one style, it has been found, the stiles are lightly curved over the arms so as to sit right with the angle of the S-shaped back splat (the central upright of its back). All three areas had been mortised in the yoke-like top rail. Though the idea of a back splat had an influence on English chairs during the Queen Anne period, wooden pieces that just to a limited capability embolden corner joints (and furthermore were loose additionally) signify an element solely to Chinese chairs. The four legs are set through the seat frame, which stops over the rounded staves. All the members are round in section or is given rounded edges—references as may be to the bamboo tradition. The seat is uncomfortable and might have had a plaited seat. These chairs needed the sitter to remain stiff and upright; for if too much weight is pushed on the back, the chair has a way of toppling. In patriarchal Chinese houses of this period armchairs likely were kept only for the senior people in the family, for they were given great esteem.

The Chinese folding stool is understood to have taken to China from the West. It does not vary that much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is intricately fixed to the two legs of the stool by means of a curved member, which is more often than not seen with metal mounts. From a Western viewpoint the resultant effect of these two furniture designs is stylized. The constructive and decorative issues are combined in a way that is at the same time naïve and refined. The pieced-together appearance is an upshot of the fact that the individual items do not look to have been put together with either glue or screws, but had been mortised onto one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had 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, possessing two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of tiny pads. The front board and a related board from the back could be folded after unscrewing some tiny iron hooks. In this way the chair was a portable piece of furniture in traveling which, at the same era, held the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is found 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 may also be made in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not held that the form actually originated in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was manufactured in considerable numbers, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up along a wall. The style asserts itself by its shapely proportions and delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, as brought out in Paris around 1750—disseminated over most of Europe and has been imitated or copied during the mid-20th century. The style owes this popularity to a combination of relaxation and elegance. The seat adheres to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back cover all the joints, which are solidly constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of relatively thick density; but all the members are deeply molded, all extraneous wood has been sanded away, and more upmarket designs might be further embellished with very delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used instead of upholstery.

English chairs from the 18th century were more differentiated in design than the French. The French touch for stylistic uniformity, which lead from the most distinguished circles in Paris and Versailles throughout 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 reknowned 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 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, purport that completely new chair forms will probably be evolved in the future.

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

Basically, bookkeeping records two types of information: (1) the current value, or equity, of an enterprise and (2) the change in value—profit or loss—taking position in the entity from a singular time period.

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

Traces of financial and numerical records have been uncovered for just about every group of people with a commercial history. Records of commercial contracts have been found in the ruins of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The double-entry manner of bookkeeping started with the furthering of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were developed in the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial bookkeeping a must-have. The history of bookkeeping, in fact, closely resembles the ancestry of commerce, industry, and government and, partially, assisted forming it. The international movement of industrial and commercial activity needed better professional decision-making methods, which then required higher sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislature became more detailed and resulted in higher requirement for information; business firms had to provide information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for their inner operations became larger.

Though bookkeeping methods can be very multifaceted, all are based on two styles of books utilised in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger contains the records of individual accounts. The daily records in the journals are put in the ledgers.

Each month, by general practice, an income statement and a balance sheet are made from the trial balance posted in the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of any changes that have occurred in the business equity as a result of the events of the period. The balance sheet provides the financial condition of the entity at any particular date taken from assets, liabilities, and the ownership equity.

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

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

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

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

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

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

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

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

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

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

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