The typical question heard when looking for a new projector for the home, office, or classroom is: will I purchase an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many brands and models available, it can be difficult for customers to make a choice between these technologies. Ultimately LCD projectors provide far superior image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with projecting a similar standard of image quality.
Visualise a set of blinds in your home covering your bedroom window. By pulling a rod you can have the shutters open or closed, according to if you want to let light in or not. And that is exactly how an LCD projector functions. Each pixel functions like a unique shutter on a set of blinds to either send 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 the point at which the projector switches on to when the image reaches your screen is vitally important with regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by separating it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels form the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to deliver the projector image. A significant point to know about LCD projectors is that all three colours are delivered onto your screen at once. The way a DLP projector operates is widely different and even the produced image appears is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image forms a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to create the image elements. The elements of the image are displayed 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 complete image. From LCD projectors, all colours are available all the time to deliver top brightness and superb colour accuracy. In DLP, just one colour is available at once, and so resulting in lower colour brightness and accuracy. Some designers have placed a white segment for the colour wheel to improve brightness overall, but this further detracts from colour accuracy.
I hear in forums all the time that DLP gives a higher contrast ratio and ergo must be superior quality. For those uncertain, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of. DLP projectors do offer high contrast specifications when compared to many LCD projectors. Initially, this seems to be a plus, however, in real life, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.
When the content you wish to bring to life includes moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector forms with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this disadvantage because all colours are projected simultaneously. DLP builders have formed 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price of these projectors make them almost impossible for most businesses and consumers.
Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and recall how the various colours of light refract various amounts when directed through the same lens. The problem with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Generally with a DLP projector, a spill of yellow colour will come up above and a superfluous blue will appear below something as simple as a straight black line. In building LCD projectors can be set to reduce these effects on the projected image, as each colour is projected on isolated LCD panels.
The only real buy point (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant for transport and has to be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is crucial to you, then the decision is no-brainer. Go for an LCD projector! LCD projectors will constantly show bright, colourful images with fewer image imperfections.

As the Dutch rose to dominance in sea power during the 17th century, the first yacht had been a pleasure craft used mostly by royalty and later by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting was found to be classy among the rich and nobility, but after that point the habit did not last.
The first yacht group in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and held great naval panoply and formality. The closest thing to racing was the “chase,” when the “fleet” pursued an imaginary enemy. The club went on, largely as a social club, until 1765, and in 1828, when conglomerating with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).
Yacht racing was first seen in some ordered method on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation 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 perpetual setting of British racing. The society at Cowes became the Royal Yachting Club, also at the ascension 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 club life was lovely. It came to be that the Royal Yachting Club boats grew in size to bigger than 350 tons.
In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English held dominance. Sailing was for the most part for leisure 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 club, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.
Kinds of sailboats
The first sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The style of sizeable yachts was initially greatly affected by the victory of America, which was drawn by George Steers for a association headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. Early yachts were not designed and manufactured in the modern sense, with only a model used. Not until the later half of the 19th century did what was known as naval architecture come into action. Not until the 1920s did the application of the study of aerodynamics do for the craft of sails and rigging what science had previously done for hulls.
Because nearly all sailboats had to be individually manufactured, there came a need for handicapping boats as this was before the one-design class boats were built. Thus, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and revised in 1919. Today, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to standard dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between such boats can be held on an even par with no handicapping at all. A great example is the standard International America’s Cup Class adopted for racers in the 1992 America’s Cup race.
For the time that yachting belonged mostly for the royal and the rich, money was no issue, and the size of boats grew, in both length and weight. The rise and preference of smaller boats came in the later 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of small craft. Following this in the 20th century, for the larger part after World War II, smaller racing and recreational yachts became commonplace, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.
Kinds of power yachts
Post the decade 1840–50, when steam began to take the place of sail power in public craft, the steam engine, and later the internal-combustion engine, were used increasingly in personal vessels. Bigger power yachts were progressed to a high element, and long-distance travel was a favourite activity of the well off. The early power yachts were paddle-wheel boats; those then gave rise to yachts powered by the completely submerged screw or propeller sort of propulsion. As well as naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts that had gasoline or diesel engines.
From the last decade of the 19th century there was a rise in the manufacture of large steam yachts. In particular within these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of at least 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service in World War II.
As more sizeable and more reliable internal-combustion engines were developed, many large boats were using them for power. The development of the diesel engine, with heavy oil for fuel, advanced in World War I. From the decade after, big power-yacht creation flourished, reaching a climax in the Orion (1930) at 3,097 tons. During that period the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.
The building of bigger power craft declined from 1932, and the trend thereafter was for smaller, less pricey yachts. From World War II, lots of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting is a globally loved activity enjoyed by thousands of yachtsmen who are actually sailing and maintaining their own small leisure boats. The number of yachts and yachtsmen has increased steadily, not only in the traditional areas on the seacoasts but also on inland waterways and lakes.

Taxes are distinguished by the impact they have on the distribution of income and wealth. A proportional tax is the kind that puts the same relative burden on each taxpayer—i.e., in the case where tax liability and income grow in the same scale. A progressive tax is characterized by a more than proportional increase in the tax onus in relation to the increase in income, and a regressive tax is recognisable by a less than proportional rise in the comparative liability. Hence, progressive taxes are thought of as taking away a lack of equality in income distribution, whereas regressive taxes might have the result of an increase in these inequalities.
The taxes that are often believed to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, might become less so for the upper-income group—in particular if a taxpayer is able to reduce his tax base by nominating deductions or by excluding particular income aspects from his taxable income. Proportional tax rates when applied to lower-income categories could also be more progressive if such personal exemptions are claimed.
Income measured over the course of a given year does not absolutely offer the most appropriate measure of taxpaying requirements. For example, transitory rises in income might be saved, and within temporary declines in income a taxpayer could choose to finance consumption by decreasing savings. So, if taxation is held in comparison with “permanent income,” it should be less regressive (or more progressive) than if compared with annual income.
Sales taxes and excises (except those on luxuries) are generally regressive, because the share of own income consumed or spent for specific goods declines as the amount of personal income is raised. Poll taxes (aka head taxes), nominated as a set amount per capita, clearly are regressive.
It is not simple to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of a lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden rests essentially on whether a national or a subnational (that is, provincial or state) tax is being considered.
In analysing the economic purpose of taxation, it is important to distinguish between several ideas of tax rates. The statutory rates will be specified in legislature; usually these are marginal rates, but for some cases they are mean rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income grows by one dollar. So, if tax liability grows by 45 cents when income rises 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 must review provisions other than 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 more than indicated in the statutory rates. Since marginal rates display how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for considering 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 reliant on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nil under a consumption-based tax.
Average income tax rates display the part of total income that is taken in taxation. The pattern of average rates is the one that is in consideration for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly 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 flip side, preferential treatment of income received fundamentally by high-income households might swamp these effects, allowing regressivity, as signified by average tax rates that fall as income increases.

The LCDs built in projection systems are generally small reflective or transmissive panels lit by a powerful arc lamp source. A number of lenses enlarges the reflected or transmitted image and then casts it on the screen. For front-projection systems the LCD is situated on the side of the screen as the viewer, while in rear-projection systems the screen is lit up from behind. Projectors of greater expense and performance can utilise three separated LCD panels, creating separate red, green, and blue images that come together to create a coloured picture on the screen.
The growing need for pictographic presentations has put a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices build with smectic liquid crystals, certain kinds of which emit a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most sophisticated smectic device. Within it the liquid crystal molecules are set out in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible outcome of the optical activity and the angle of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. So, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up 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 produced for large passive-matrix displays, but their high cost and intricacy has impeded them from making any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as elements in projection systems or as viewfinders in digital cameras. Their speedy reacting allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick speed (around 100 cycles a second). For example, the liquid crystal may be switched to a transmissive state in the red and green periods but to a nontransmissive state for the blue period, with the end result that the eye sees an average of red and green light, or the colour yellow.

Out of each of the furniture objects, the chair may be primary. While most other pieces (except the bed) are designed to support objects, the chair supports the human form. The term chair is intended to be used here in the wider sense, from stool to throne to derivative chairs for example the bench and sofa, which should be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly labeled.
The social history of the chair is as exciting as its history as a creative craft. The chair is not just a physical support or aesthetic craft; it can also be symbolic of social standing. From the Medieval royal courts there were important distinctions between sitting on a chair with arms, on a chair with a back but without arms, and having to sit on a stool. Since the 20th century, a director’s and/or manager’s chair has become an indicator of superior standing, like in democratic government debate the speaker sits on a high-set platform.
As a furniture creation, the chair ranges from a range of variations. There are chairs created to match man’s age and physical form (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). From historical days there were chairs for births (birth chairs); since the 20th century, there have been chairs used for ending life (the electric chair). There are 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 up, chairs on wheels, and chairs on runners.
Contemporary lifestyle has designated particular chairs in automobiles and aircraft. Each of these chair shapes have been perfected to fit to evolving human requirements. Due to its significant association with man, the chair comes to its full importance only when being used. Although it doesn’t make any difference to one’s appreciation of a cupboard or a dresser drawers if there might be things inside or not, a chair is understood best and evaluated by a person sitting in it, because chair and sitter require each other. Thus the various elements of the chair were named likened to the elements of the human form: arms, legs, feet, back, and seat.
Because the first work of your chair is to support our body, its credit is valued principally by how fully it does measure up to this practical job. Within the build of a chair, the carpenter is restricted by some static regulation and principal measurements. Under these boundaries, however, the chair builder has marvellous freedom.
The history of the chair extended over an epoch of several thousand years. There are societies that had made unique chair shapes, expressive of the principal object in the areas of craft and aesthetics. Out of these such civilisations, special 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 lives of Louis XV and Louis XVI.
Egypt
Two ancient Egyptian chair forms, both the upshot of skilled craft, are today seen from discoveries made in tombs. One of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs shaped not unlike those of some animal, a curved seat, and a sloping back supported from vertical stretchers. In this design a strong triangular construction was created. There seems to be no noteworthy change between the structure of Egyptian thrones and chairs for ordinary peasantry. The general variation lied in the brand of ornamentation, in the choice of pricier inlays. The Egyptian folding stool most likely was created as an easily stored seat for army. As a camp stool this kind existed til much later points. But the stool also then existed in the use of a ceremonial seat, its mechanical task as a folding stool fast forgotten. This can now be seen, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the form of folding stools but can’t be folded as the seats were worked from wood. The easy manufacture of the folding stool, composed of two frames that spin on metal bolts and support a seat of leather or fabric fastened between them, can be seen but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this kind is the folding stool, made of ashwood, found at Guldhøj (National Museum in Copenhagen).
Greece and Rome
The unique Greek chair, the klismos, is recognised not from any ancient specimen still extant but as found in a large amount of pictorial items. The most recognisable is the klismos placed on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of those legs are displayed. These strange legs were probably manufactured from bent wood and were in that case needed to bear a large amount of pressure from the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore very durable and were visibly indicated.
The Romans adopted the Greek designs; existing statues of seated Romans display evidence of a heavier and are a kind of crudely designed klismos. Both designs, light and heavy, were popularised within the Classicist epoch. The klismos style can be evidenced in French Empire design, in English Regency, and in special forms of considerable originality around Denmark and Sweden around 1800.
China
The progression of the chair in China isn’t able to be tracked as long as the history of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full folio of images and paintings had been preserved, showing the insides and exterior of Chinese households and the furniture. Another preservation from the 16th century are some chairs of wood or lacquered wood, that hold an interesting familiarity to styles of older chairs.
As in Egypt, there existed two major chair designs in China: a chair with four legs and a folding stool. That chair can be seen both with or without arms however always having the square seat and straight stiles (standing side supports) to support the back. In one design, however, the stiles had been slightly curved by the arms in order to fit the shape of the S-shaped back splat (the basic upright of a chairback). Together, all three areas had been mortised in the yoke-like top rail. Despite that the design of the Chinese back splat then had an inspiration for English chairs of the Queen Anne period, wooden sections that could merely to a limited limit embolden corner joints (and furthermore were loose in the result) indicate an element signatory to Chinese chairs. The four legs pass through the seat frame, which ends over the rounded staves. Members are round in section or have rounded edges—referable as may be to the bamboo tradition. The seat is uncomfortable and may have a plaited seat. These chairs required the sitter to stay stiff and upright; for when too much weight is exerted on the back, the chair has a habit of toppling over. In patriarchal Chinese households of this era armchairs probably were kept only for the senior people, for they were greatly respected.
The Chinese folding stool is thought to have been brought to China from the West. It does not differ that much from the Egyptian and Scandinavian folding stools, but it has a variation in that the top rail is intricately affixed to the two legs of the stool by using a curved member, which is usually designed with metal mounts. From a Western viewpoint the resulting effect of both furniture forms is stylized. The construction and decoration aspects are combined in a way that is all at once both naïve and refined. The pieced-together appearance is an outcome of the way that the individual items do not seem to have been put together by use of either glue or screws, but were mortised onto one another and fixed in position in the manner of a Chinese puzzle.
Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Works of art show a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between the layers, stitched to bring up a pattern of small pads. The front board and a related board at the back could be folded after loosening some tiny iron hooks. Therefore the chair was a readily portable piece of furniture in traveling which, at the same period, held the dignity of a four-legged, high-backed armchair.
The Netherlands: 17th century
A low, square, upholstered design of chair can be displayed in engravings of the inside of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair is also found in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the form actually originated in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slim measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was produced in vast quantities, as evidenced from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up against a wall. The style asserts itself by its elegant proportions and delicate upholstery in gilt leather or fabric bordered with fringes.
France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is to say, as developed in Paris around 1750—conquered most of Europe and was imitated or copied in the mid-20th century. The model owes this popularity to a combination of leisure and elegance. The seat adheres to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions are found between seat frame, legs, and back cover all the joints, which are constructed on craftsmanlike principles even with the absence of stretchers between the legs.
French Rococo chairs and imitations of them have wood of quite thick dimensions; but all members are deeply molded, all extraneous wood has been sanded away, and finer items would be further embellished with highly delicate and decorative engravings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for the upholstery on the seat, back, and armrests; cane is in some cases used instead of upholstery.
English chairs in the 18th century were more varied in design than the French. The French touch for stylistic uniformity, which came from the royal circles in Paris and Versailles through most of France and found favour in several 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
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 styles 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 transactions of a business. Bookkeeping grants the details from which accounts are prepared but is a different process, preliminary to accounting.
Essentially, bookkeeping finds two kinds of information: (1) the current value, or equity, of the business and (2) changes in value—profit or loss—taking place in the entity during a given time period.
Management officials, investors, and credit grantors all require this kind of information: management so as to analyse the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to interpret the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an enterprise in finding whether to grant a loan.
Traces of financial and numerical records can be uncovered for almost every country with a commercial backbone. Records of trading contracts were uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates have been made in ancient Greece and Rome. The double-entry manner of bookkeeping began with the furthering of the enterprising republics of Italy, and manuals for bookkeeping were created during the 15th century in some Italian cities.
Within the late 18th and early 19th centuries, the Industrial Revolution provided an important stimulus to accounting and bookkeeping.
The rise of manufacturing, trading, shipping, and subsidiary services made perfect financial records a paramount factor. The past of bookkeeping, in fact, reflects the past of commerce, industry, and government and, in some part, assisted in shaping it. The global expansion of industrial and commercial activity required more professional decision-making methods, which in turn called for higher sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government regulation became more detailed and resulted in increased demand for information; entities 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 become larger, and the need for bookkeeping for their own departmental operations became higher.
Though bookkeeping procedures can be rather multifaceted, it is all based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger must have the details of individual accounts. The daily records from the journals are put in the ledgers.
At the end of every month, generally, an income statement and a balance sheet are prepared from the trial balance posted within the ledger. The point of the income statement or profit-and-loss statement is to provide an analysis of those changes that happen in the entity equity resulting due to the events of the period. The balance sheet gives the financial position of the business at a particular day 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 wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.
New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.
Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.
There is no better feeling than being in the cockpit during your jet fighter flight.
