The most common question customers ask when acquiring a new projector for the home, office, or classroom is: should I get an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different models available, it can be challenging for consumers to decide between these technologies. It comes down to the fact that LCD projectors give better image quality and colour accuracy. The following article will explain why DLP projectors struggle with creating a similar grade of image quality.

Imagine a set of blinds in your home for your bedroom window. By twisting a rod you can turn the shutters open or closed, according to whether you want to let light in or not. And such is exactly how an LCD projector functions. Each pixel functions like a unique shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as professionals like to call them. Each pixel element operates 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 picture reaches your screen is ultimately important to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 stand alone LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then combined in a glass prism to deliver the projector image. Something important to understad about LCD projectors is that all three colours are sent onto your projector screen all at once. The way a DLP projector runs is widely different and even the produced image appears is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming 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 form the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eye will then pull together each coloured element of the image into the complete image. Using LCD projectors, all colours are available all the time to deliver the best brightness and superb colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some designers have added a white segment for the colour wheel to improve overall brightness, but this further degrades colour accuracy.

I see in forums all the time that DLP gives a higher contrast ratio and thus must be superior quality. For those who do not know, 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 able to produce. DLP projectors do have high contrast specifications compared to most LCD projectors. Initially, this appears to be a benefit, however, in truth, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you want to bring to life requires moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images keep changing between the time red, blue and green colours are shone. LCD projectors do not have this disadvantage because all the colours are sent with the others. DLP designers have come up with 3DLP solutions using 3 chips to resolve the colour break up error, but the price of these projectors make them almost impossible for most businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and recall how the different colours of light refract various amounts when shone through the same lens. The disadvantage 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 a different way. Generally with a DLP projector, some extra yellow colour will come up above and a spill of blue will appear below an image of something as simple as a lone black line. During manufacturing LCD projectors can be fixed to take away these effects on the projected image, as each colour is processed on its own LCD panels.

The sole true buy point (excluding price) with going with a DLP projector is its smaller size and weight. However, this is only relevant for transporting the device and cannot be traded off against the image superiority of LCD projectors. If resulting picture quality is crucial to you, then the solution is simple. Go for an LCD projector! LCD projectors will definitely produce bright, colourful images with fewer image imperfections.

As the Dutch found preeminence in sea power during the 17th century, the first yacht became a pleasure craft used initially by royalty and secondly by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 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 was found to be fashionable for the wealthy and nobility, but after that point the trend did not last.

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

Yacht racing was first seen in some ordered manner on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to monarchy in 1820, it was then called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, 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 continued setting of British yachting. The club 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 tests for great stakes were held, and the social life was splendid. Ultimately Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English had dominance. Sailing was for the most part for leisure and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a standard of luxury and elegance for the later yachts in that area from the late 19th century. The first enduring American yacht organisation, 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 followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of large yachts was initially greatly put upon by the victory of America, which was drawn by George Steers for a group started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. Earlier yachts were not designed and crafted in the modern sense, with merely 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 employment of the study of aerodynamics do for the design of sails and rigging what science had already done for hulls.

Because most of all sailboats had been individually custom-built, there arose a requirement for handicapping boats before the one-design class boats were designed. Hence, a rating rule was decreed, which resulted in the International Rule, adopted in 1906 and revised in 1919. Today, one of the fastest flourishing areas in sailing 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 areas (for an example of a two-person sailboat, see illustration). Racing these boats can be had on an even keel with no handicapping required. A prime example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting belonged primarily for the royal and the wealthy, expense was no issue, and the size of boats developed, in both length and weight. The promotion and popularity of smaller craft occurred 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) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the hardiness of less sizeable yachts. Thereafter in the 20th century, for the larger part after World War II, smaller racing and leisure craft became commonplace, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam was set to replace sail power in market boats, the steam engine, and later the internal-combustion engine, were increasingly used in personal boats. Bigger power yachts were developed to a high degree, and long-distance cruising turned into a preferred pastime of the well off. The first power yachts were paddle-wheel boats; those then gave rise to yachts powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant boats, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

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

As more sizeable and better quality internal-combustion engines were produced, many bigger boats were using them for power. The creation of the diesel engine, using heavy oil for fuel, progressed from World War I. From the decade that followed, bigger power-yacht building grew, reaching a climax in the Orion (1930) at 3,097 tons. During that point the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power craft lessened from 1932, and the style after that was for smaller, less expensive yachts. From World War II, lots of small naval boats were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally beloved sport enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small pleasure craft. The popularity of boats and owners has increased steadily, not only in the traditional areas 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 puts the same relative requirement on every taxpayer—i.e., in the case where tax liability and income move in equal levels. A progressive tax is recognisable by a larger than proportional rise in the tax liability relative to the growth in income, and a regressive tax is recognised by a less than proportional increase in the comparative onus. Therefore, progressive taxes are regarded as taking away a lack of equality in income distribution, but regressive taxes are found to cause an increase in these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, could become less so within the upper-income categories—especially if a taxpayer is able to lower his tax base by claiming deductions or by excluding some income parts from his taxable income. Proportional tax rates that are applied to lower-income classes can also be more progressive if such personal exemptions are claimed.

Income measured over a given year may not definitely offer the best measure of taxpaying requirements. For example, transitory increases in income could be saved, and during temporary declines in income a taxpayer may opt to pay for consumption by decreasing savings. Thus, if taxation is made comparable with “permanent income,” it would be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (with the exception of those on luxuries) are usually regressive, because the spread of personal income consumed or spent on specific goods declines as the level of personal income is raised. Poll taxes (also called head taxes), nominated as a set amount per capita, obviously are regressive.

It is not easy to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden lays essentially 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 several points of tax rates. The statutory rates will be nominated in law; often these are marginal rates, but sometimes they are median rates. Marginal income tax rates note the fraction of incremental income that is demanded by taxation when income grows by one dollar. Hence, if tax liability increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax laws generally contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates must take into account provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than indicated by the statutory rates. Since marginal rates display how after-tax income increases or decreases in response to changes in before-tax income, they are the important ones for considering incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applicable to income from business and capital, because it may depend on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines 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 required in taxation. The pattern of average rates is the one that is important for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally increase with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households may dwarf these effects, producing regressivity, as indicated by average tax rates that lower as income grows.

The LCDs put in projection systems are typically small reflective or transmissive panels set off by a bright arc lamp source. A line of lenses enlarges the reflected or transmitted image and then displays it onto the screen. In front-projection systems the LCD is set on the same side of the screen as the viewer, however in rear-projection systems the screen is illuminated from behind. Projectors of higher expense and performance might be found with three distinct LCD panels, reflecting separate red, green, and blue images that come together to create a coloured picture on the screen.

The growth in need for visual presentations has granted a growth in emphasis on the switching speed of liquid crystals. This has demanded the manufacture of devices utilizing smectic liquid crystals, particular types of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. Within it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and throughout the layers the molecules are slanted, as shown in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible turn up of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. So, there must be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The consequential change in optical properties can cause a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been produced for larger passive-matrix presentations, but their high cost and complex detail has stopped them from enjoying any remarkable movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be used in time-sequential colour systems, in which high cost colour filters are removed for a coloured backlight that flashes red, green, and blue in fast succession (around 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods and then to a nontransmissive state for the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

From all the furniture objects, the chair may be the primary one. While the majority of other forms (save the bed) are meant to support objects, the chair supports a human form. The term chair should be viewed here in the larger sense, from stool to throne to complex types for example the bench or 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 obviously labeled.

The social history of the chair is as stimulating as its history as a creative art. The chair is not merely a physical support or an aesthetic piece of art; it historically was an indicator of social hierarchy. Within the old royal courts there were important connotations between having a chair with arms, on a chair with a back but without arms, and having to utilise a stool. Since the recent century, a director’s or manager’s chair has developed an indicator of superior standing, as well as in democratic parliaments the speaker sits on a raised platform.

As its furniture construction, the chair can be employed for a variety of different purposes. There are chairs designed to suit man’s age and physical form (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). In the olden days there were chairs for births (birth chairs); in the 20th century, there have been chairs used to die in (the electric chair). We design 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.

Modern day living has developed particular chairs in automobiles and aircraft. Each of these chair shapes has perfected to match to differing human desires. From its significant connection with man, the chair appears to its full purpose only when utilised. Though it does not make a difference to one’s appreciation of a cupboard or a chest of drawers if there are items inside or not, a chair is really seen best and regarded best by a person sitting in it, for chair and sitter need each other. Thus the several areas of the chair are given names likened to the limbs of the human body: arms, legs, feet, back, and seat.

Because the simple role of a chair is to support the body, its credit is judged primarily for how completely it fulfills this practical job. Within the creation of the chair, the chair maker is limited for the static regulation and principal measurements. Within these rules, however, the chair builder has great freedom.

The history of the chair is an era of several thousand years. There were societies that had distinctive chair shapes, as seen of the leading endeavour in the spheres of skill and art. From such civilisations, particular mention needs to 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of expert make, were found from tombs. The first of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs shaped similar to those of a chosen animal, a curved seat, and with a sloping back supported over vertical stretchers. In this way a strong triangular construction was crafted. There was apparently no noteworthy difference in the creation of Egyptian thrones and chairs for typical citizens. The general difference existed in the level of ornamentation, in the choice of more costly inlays. The Egyptian folding stool probably was manufactured as an easily stored seat for officers. As a camp stool the form existed for much later periods. But the stool then also took on the use of a ceremonial seat, its technical task as a folding stool being forgotten. This can already 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 made in the form of folding stools but aren’t able to be folded as the seats were made out of wood. The plain build of the folding stool, consisting of two frames that cycle on metal bolts and hold a seat of leather or fabric held between them, then appeared but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this kind is the folding stool, made from ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not as any ancient fossil still in form but in a trove of pictorial evidence. The better recognised is the klismos placed on the Hegeso Stele at the Dipylon burial area in outer Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of them were shown. These odd legs were considered to have been manufactured with bent wood and were in that case put under extreme pressure from the weight of the sitter. The joints holding the legs to the frame of the seat were therefore very solid and were overtly pointed out.

The Romans adopted the Greek design; quite a few models of seated Romans show chairs of a heavier and which appear to be a slightly less intricately crafted klismos. Both designs, light and heavy, were brought back as part of the Classicist period. The klismos style can be seen in French Empire design, in English Regency, and in particular forms of marked iconicism in Denmark and Sweden during 1800.

China
The ancestry of the chair in China cannot be tracked as long as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) a full series of images and paintings has been kept, detailing the insides and exteriors of Chinese houses and the kinds of furniture. Also kept of the 16th century are a trove of chairs constructed from wood or lacquered wood, that bear an interesting similarity to images of ancient chairs.

Just as in Egypt, there was two major chair designs in China: a chair of four legs and a folding stool. The four-legged chair was seen both with and without arms though always with a square seat and straight stiles (vertical side supports) to give support to the back. In one type, it has been found, the stiles could be slightly curved above the arms for the purpose of conform to the form of the S-shaped back splat (the central upright of a back). All three limbs were mortised into the yoke-like top rail. While the style of the back splat then had a foundation for English chairs within the Queen Anne period, wooden pieces that just to a limited capability stabilise corner joints (as well as being loose in the bargain) signify a design exclusive to Chinese chairs. The four legs sit through the seat frame, which closes around the rounded staves. All members are round in section or possesses rounded edges—acknowledging perhaps to the bamboo tradition. The seat is not pleasant and may have had a plaited bottom. These chairs required the sitter to hold themselves stiff and upright; for when too much weight is forced on the back, the chair has a tendency to topple over. In patriarchal Chinese households of this epoch armchairs most likely were only for the senior persons in the family, for they were esteemed greatly.

The Chinese folding stool is presumed to have been brought to China from the West. It is akin very much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is delicately affixed to the two legs of the stool in a curved member, which is generally provided with metal mounts. From a Western understanding the resulting effect of these furniture styles is stylized. The manufacture and decoration parts are combined in a style that is all at once naïve and refined. The pieced-together appearance is a result of the fact that the individual parts do not seem to have been put together by use of either glue or screws, but have been mortised into one another and fixed in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its mark on the chair. Works of art project a design of chair with a relatively brusque wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in the layers, stitched to bring up a pattern of tiny pads. The front board and a similar board from the back could be folded after loosening some small iron hooks. Thus the chair was a readily portable piece of furniture when traveling which, at the same time, granted the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is displayed in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair may also be seen in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the form actually was born in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of thin shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in impressive amounts, as indicated from one of Abraham Bosse’s engravings, in which there is an entire row of such chairs lined up along a wall. The style asserts itself by virtue of its shapely proportions and expensive 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 developed in Paris around 1750—conquered most of Europe and has been imitated or copied into the mid-20th century. The design owes the popularity to a combination of relaxation and delicacy. The seat conforms to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of relatively thick measurements; but each member is deeply molded, all superfluous wood has been taken away, and finer chairs would be further embellished with intricately delicate and decorative engraving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all the upholstery on the seat, back, and armrests; canework is in some cases used rather than upholstery.

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

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

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

In cheaper products 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 function of a business. Bookkeeping gives the information from which accounts are drafted but is a distinct process, required prior to accounting.

Fundamentally, bookkeeping grants two types of information: (1) the current value, or equity, of an entity and (2) the change in value—profit or loss—taking position in the business during a particular period of time.

Management officials, investors, and credit grantors all demand this information: management so as to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to understand the outcome of business operations and make decisions for buying, holding, and selling securities; and credit grantors to assess the financial statements of a business in assessing whether to allow a loan.

Traces of financial and numerical record charts can be uncovered for nearly every group of people with a commercial backbone. Records of commercial contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates were kept in ancient Greece and Rome. The two-entry process of bookkeeping started with the progression of the enterprising republics of Italy, and tutorials for bookkeeping were created within the 15th century in several Italian cities.

During the late 18th and early 19th centuries, the Industrial Revolution granted an important stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a must-have. The ancestry of bookkeeping, in fact, resembles the history of commerce, industry, and government and, in some part, helped to form it. The global revolution of industrial and commercial activity needed better professional decision-making procedures, which in turn called for higher sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government legislation became more detailed and resulted in even greater demand for information; business firms had to have information available to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the requirement for bookkeeping for departmental operations became higher.

Though bookkeeping methodology can be very multifaceted, all of it is based on two types of books used in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so on), and the ledger must have the records of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are made from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to present an analysis of those changes that occurred in the ownership equity resulting from the events of the period. The balance sheet gives the financial situation of the business at a particular date in terms of 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.
