The most common question that is asked when acquiring 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, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and different models available, it can be overwhelming for clients to make a choice between these technologies. It comes down to the fact that LCD projectors give far better image quality and colour accuracy. The article below will explain why DLP projectors struggle with projecting the same rate of image quality.
Imagine a set of blinds in your room over your bedroom window. By a twist of a rod you can have the shutters open or closed, depending on whether you want to let light in or not. This is exactly how an LCD projector works. Each pixel works like a unique shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is formed 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 time the projector turns on to when the content reaches your screen is extremely significant to image quality, brightness and colour accuracy. LCD projectors project 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 create the elements of the image by processing each pixel on and off. The pixels are then meshed in a glass prism to create the projector image. A point to know about LCD projectors is that all three colours are sent onto your screen all at the same time. The way a DLP projector works is widely different and even the produced image comes out is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image creates a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then pull together each coloured element of the image into the full image. From LCD projectors, all colours are available all the time to form the best brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, causing lower colour brightness and accuracy. Some DLP manufacturers have put a white segment in the colour wheel to improve brightness overall, but this goes and degrades colour accuracy.
I hear in forums all the time that DLP provides a higher contrast ratio and ergo must be superior. For those who are unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is able to produce. DLP projectors do have high contrast specifications as compared to the majority of LCD projectors. At first glance, this seems to be a plus, however, in real life, the true black level is determined by the ambient light in the room when the projector is being utilised. Do not be duped by contrast specifications on websites and in brochures.
When the content you wish to view requires moving images, DLP projection technology can also have image marks, 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 shone. LCD projectors do not have this problem because every colour is delivered simultaneously. DLP manufacturers have developed 3DLP solutions using 3 chips to solve the colour break up problem, but the price tag of these projectors make them not practical for the majority of businesses and consumers.
Another differentiation between LCD and DLP is how they compensate for the refractive qualities of light. Think back to high school science, and remember how different colours of light refract varied amounts when projected through the same lens. The disadvantage with DLP projectors is that they utilise the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light in a different way. Usually with a DLP projector, an extra yellow colour will show above and a superfluous blue will be projected below an image containing something as simple as a lone black line. In building LCD projectors can be set to reduce these effects on the projected image, as each colour is directed on isolated LCD panels.
The sole true plus (excluding price) with choosing a DLP projector is its smaller size and weight. However, this is only relevant in regard to transporting the device and needs to be traded off against the image superiority of LCD projectors. If the result of the picture quality is crucial to you, then the solution is easy. Go for an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image blips.

As the Dutch found dominance in sea power during the 17th century, the early yacht had been a leisure craft used mostly by royalty and secondly by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as 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 gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 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 became popular among the wealthy and royalty, but after that point the habit did not last.
The first yacht group in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had great naval panoply and gravity. The closest thing to racing was the “chase,” for which the “fleet” pursued a fictional enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, after joining with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).
Yacht racing began in some organized manner on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been started at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent - the strait between the mainland and the Isle of Wight - the continued site of British yacht racing. The association at Cowes became the Royal Yachting Club, also at the rise of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing matches for great bids were held, and the social life was wonderful. Eventually Royal Yachting Club boats grew in size to over 350 tons.
In North America, yachting began with the Dutch in New York in the 17th century and went on when the English took dominance. Sailing was for the most part for leisure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht society, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while aboard his schooner Gimcrack.
Kinds of sailboats
Early sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The style of large yachts was initially largely impacted by the victory of America, which was drawn by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its victory at Cowes in 1851. The first yachts were not designed and crafted in a contemporary sense, with just a model being used. Not until the second half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the application of the study of aerodynamics do for the craft of sails and rigging what it had already done for hulls.
Because almost all sailboats were individually built, there arose a requirement for handicapping boats before the one-design class boats were made. Hence, a rating rule was written, which ended up in the International Rule, taken on in 1906 and amended in 1919. In modern times, one of the most rapidly flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to standard specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for these boats can be done on an even keel with no handicapping required. A prime example is the standard International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.
For the time that yachting was done primarily for the aristocracy and the wealthy, cost was no problem, and the size of boats developed, in both length and weight. The ascendancy and desire of smaller craft happened 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 journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of small boats. Following this in the 20th century, particularly after World War II, smaller racing and leisure yachts became more common, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.
Kinds of power yachts
Following the decade 1840–50, at which point steam was set to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were employed increasingly in personal vessels. Bigger power yachts were furthered to a high element, and long-distance sailing turned into a fond activity of the wealthy. The early power yachts were paddle-wheel boats; these then made way to those powered by the fully submerged screw or propeller kind of propulsion. As well as naval and merchant craft, auxiliaries carrying both sail and power were the yacht standard for a number of years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were only power yachts that had gasoline or diesel engines.
In the last decade of the 19th century there was a push in the construction of more sizeable steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of 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 was used in active service in World War II.
As larger and more dependable internal-combustion engines were created, many big craft were using them for power. The creation of the diesel engine, using heavy oil for fuel, was furthered from World War I. From the decade following that, bigger power-yacht manufacture blossomed, climaxing in the Orion (1930) at 3,097 tons. During that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.
The manufacture of large power craft lessened after 1932, and the fashion from then was for smaller, less costly boats. After World War II, a lot of small naval craft were sold to private owners for conversion to yachts. In the late 20th century, yachting is a globally popular activity enjoyed by thousands of yachtsmen personally manning and maintaining their own small recreational craft. The number of craft and sailors is increasing steadily, not only in the traditional areas along the beach but also on inland waterways and lakes.

Taxes can be categorized by the impact they have on the allocation of income and wealth. A proportional tax is a tax that puts the same relative burden on each taxpayer—i.e., in the case where tax liability and income increase in relative proportion. A progressive tax is recognisable by a more than proportional growth in the tax onus in regard to the increase in income, and a regressive tax is characterized by a less than proportional rise in the related burden. Therefore, progressive taxes are regarded as fighting a lack of equality in income distribution, whereas regressive taxes are believed to have the result of increasing these inequalities.
The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so for the upper-income demographic—in particular if a taxpayer is allowed to reduce his tax base by claiming deductions or by leaving out some particular income elements from his taxable income. Proportional tax rates when applied to lower-income demographics would also be more progressive if such personal exemptions are made.
Income measured over a given year does not absolutely provide the most appropriate measure of taxpaying requirements. For example, transitory rises in income may be saved, and in temporary declines in income a taxpayer could select to provide for consumption by decreasing savings. Thus, if taxation is regarded with “permanent income,” it would be less regressive (or more progressive) than when it is made comparable with annual income.
Sales taxes and excises (except luxuries) are mostly regressive, because the portion of personal income consumed or spent for a specific good lowers as the rate of personal income grows. Poll taxes (also called head taxes), nominated as a set amount per capita, clearly are regressive.
It is difficult to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of a lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being considered.
In regarding the economic purpose of taxation, it is necessary to differentiate between several concepts of tax rates. The statutory rates are dictated in the law; commonly these are marginal rates, but sometimes they are mean rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income is increased by one dollar. Ergo, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations usually contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates must regard provisions in addition to 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 specified within the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, because it may rely 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 fraction of total income that is demanded in taxation. The pattern of average rates is the one that is in consideration for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally grow with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households could dwarf these effects, producing regressivity, as shown by average tax rates that lessen as income rises.

The LCDs utilised for projection systems are most often small reflective or transmissive panels lit by a bright arc lamp source. A number of lenses magnifies the reflected or transmitted image then displays it on the screen. With front-projection systems the LCD is placed on the same area of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of higher expense and capacity sometimes have three discrete LCD panels, forming separate red, green, and blue images that come together to make a coloured picture on the screen.
The growth in need for film displays has granted a growing emphasis on the switching speed of liquid crystals. This has demanded the manufacture of devices build with smectic liquid crystals, certain ones of which emit a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed smectic device. Within it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as demonstrated in the figure. The host liquid crystal possesses optically active molecules, and a scarcely perceptible result of the optical activity and the tilt 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 throughout the plane of the layers. Thus, there must be a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding 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 create a change from light to dark in the case that one or more polarizers are used.
SSFLC devices have been commercialized for large passive-matrix presentations, but their cost and detail has prevented them from enjoying any great impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some promise for use as elements in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be employed in time-sequential colour systems, in which high cost colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick pulsing (approx 100 cycles every 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, with 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 might be the imperative one. While many other pieces (save the bed) are devised to support objects, the chair supports a human form. The term chair is looked upon here in the widest sense, from stool to throne to further items including the bench or sofa, which should be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly labeled.
The social history of the chair is as interesting as its history as art and craft. The chair is not merely a physical support or aesthetic piece; it was also semiotic of social status. In the Medieval royal courts there were significant differences between having a chair with arms, on a chair with a back but no arms, or worse having to sit on a stool. In the 20th century, the director’s and/or manager’s chair has risen an indicator of superior status, and in democratic government meeting the speaker sits on a higher floor.
In a furniture construction, the chair can be utilised for a number of different forms. There are chairs manufactured to suit man’s age and physical abilities (the high chair, the wheelchair) and to connotate his status in society (the executive chair, the throne). During historical times there were chairs for birthing (birth chairs); during the 20th century, there have been chairs used 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 lifestyle has designated unique chairs for automobiles and aircraft. Every one of these chair kinds have perfected to suit to evolving human needs. From its unique importance with man, the chair appears to its full meaning only when in employ. Whereas it does not make any difference to one’s appreciation of a cupboard or a chest of drawers if there are items inside or not, a chair is seen best and regarded best with a person using it, because chair and sitter suit one another. Thus the several elements of a chair have been given labels likened to the elements of the human shape: arms, legs, feet, back, and seat.
Because the first work of your chair is to support the human body, its credit is evaluated principally by how suitably it does fulfill this practical use. In the construction of the chair, the carpenter is limited in some static rules and principal measurements. Inside these regulations, however, the chair creator has large freedom.
The history of the chair covered dates of several thousand years. There were cultures that held iconic chair shapes, expressive of the foremost task in the arenas of technique and design. In these such peoples, 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 lifetimes of Louis XV and Louis XVI.
Egypt
Two ancient Egyptian chair forms, both the construct of careful make, were seen from tombs. One of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs formed akin to those of some animal, a curved seat, and leading to a sloping back supported by vertical stretchers. In this design a stable triangular form was created. There was to our knowledge no marked difference in the structure of Egyptian thrones and chairs for regular citizens. The simple change lies in the intricacy of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool in all probability was manufactured to be an easily stored seat for army. As a camp stool this form stayed for much later days. But the stool then also played the role of a ceremonial seat, its technical role as a folding stool neglected or forgotten. This can today be found, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were in the form of folding stools but are not able to be folded as the seats were formed of wood. The easy construction of the folding stool, made of two frames that cycle on metal bolts and have a seat of leather or fabric held between them, is seen again but some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this kind is the folding stool, crafted out of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).
Greece and Rome
The typical Greek chair, the klismos, is found not from any ancient object still around but as found in a trove of pictorial items. The significant kind is the klismos placed on the Hegeso Stele at the Dipylon burial ground just out of Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of these legs would be displayed. These unique legs were most likely to have been executed from bent wood and were therefore bore great pressure with the weight of the sitter. The joints holding the legs to the frame of the seat were therefore very solid and were overtly signified.
The Romans embued the Greek style; designs of statues of seated Romans are examples of a denser and which appear to be a slightly more crudely designed klismos. Both designs, light or heavy, were brought back as part of the Classicist epoch. The klismos style can be seen in French Empire styles, in English Regency, and in special forms of marked individuality in Denmark and Sweden from 1800.
China
The progression of the chair in China can not be tracked as long as in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken folio of sketches and paintings was preserved, showing the interior and outer parts of Chinese households and their furniture. Preserved also of the 16th century are a collection of chairs constructed of wood or lacquered wood, that hold an intriguing familiarity to pictures of ancient chairs.
As in Egypt, two chair designs dominated in China: a chair with four legs and a folding stool. This four-legged chair was designed both with and without arms however always having the square seat and straight stiles (upright side supports) to support the back. In one design, it has been seen, the stiles could be delicately curved above the arms so as to fit the structure of the S-shaped back splat (the main upright of a chairback). All three parts were mortised into the yoke-like top rail. Though the idea of this back splat later had an inspiration for English chairs of the Queen Anne period, wooden sections that merely to a particular extent embolden corner joints (and are loose as well) indicate a feature solely to Chinese chairs. The four legs pass through the seat frame, which ends over the rounded staves. All the members are round in section or possesses rounded edges—a left over perchance to the bamboo tradition. The seat is not comfortable and may have had a plaited form. These chairs required the sitter to stay stiff and upright; for if too much weight is placed on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this period armchairs presumably were reserved only for older people in the family, for they were held in great respect.
The Chinese folding stool is presumed to have travelled to China from the West. It is akin that much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is elegantly fixed to the two legs of the stool with a curved member, which is often possessing metal mounts. From a Western understanding the overall effect of these furniture items is stylized. The manufacture and decorative aspects are combined in a style that is all at once naïve and refined. The pieced-together appearance is a result of the manner that the individual items do not appear to have been adjoined by means of either glue or screws, but are mortised into one another and locked into position in the style of a Chinese puzzle.
Spain: 17th century
The Golden Age of Spain during the 17th century also had its name on the chair. Works of art display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to produce a pattern of tiny pads. The front board and a similar board in the back could be folded after unscrewing some small iron hooks. Therefore the chair was a readily portable piece of furniture in traveling which, in the same period, had the status of a four-legged, high-backed armchair.
The Netherlands: 17th century
A low, square, upholstered kind of chair is evidenced in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not held that the style actually was born in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in vast numbers, as surmisable from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up by a wall. The form asserts itself by its elegant proportions and expensive upholstery in gilt leather or fabric framed with fringes.
France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is to say, as progressed in Paris around 1750—spread over most of Europe and was imitated or copied in the mid-20th century. The design owes its popularity to a combination of comfort and elegance. The seat adheres 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 are achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike practices even with the absence of stretchers between the legs.
French Rococo chairs and imitations of those use wood of relatively thick density; but every member is deeply molded, all extraneous wood has been cut away, and more expensive examples would be further embellished with highly delicate and decorative woodwork. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for the upholstery on the seat, back, and armrests; canework is sometimes used instead of upholstery.
English chairs in the 18th century were more open in style than the French. The French taste for stylistic uniformity, which spread from the royal circles in Paris and Versailles through most of France and was popularised 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
During the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.
In cheaper versions of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.
Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, purport that completely new chair forms will probably be evolved in the future.

Bookkeeping is the charting of the money values of the operation of a business. Bookkeeping creates the details from which accounts are made but is a different process, prior to accounting.
Fundamentally, bookkeeping provides two types of information: (1) the current value, or equity, of a business and (2) any changes in value—profit or loss—taking position in the business during a given time.
Management officials, investors, and credit grantors all have to have such information: management in order to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to interpret the outcomes of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of a business in finding whether to give a loan.
Traces of financial and numerical recordkeeping are found for nearly every civilization with a commercial background. Records of trade contracts were uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The double-entry method of bookkeeping began with the progression of the commercial republics of Italy, and tutorial books for bookkeeping were created during the 15th century in various Italian cities.
Within the late 18th and early 19th centuries, the Industrial Revolution granted a notable stimulus to accounting and bookkeeping.
The development of manufacturing, trading, shipping, and subsidiary services made accurate financial books a paramount factor. The ancestry of bookkeeping, in fact, closely reflects the history of commerce, industry, and government and, in some part, assisted forming it. The international movement of industrial and commercial activity demanded greater professional decision-making methodology, which in turn demanded greater sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government regulation became more detailed and resulted in higher demand for information; business entities had to provide information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the demand for bookkeeping for their own inner operations went up.
Though bookkeeping methodology can be very multifaceted, it is all based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so forth), and the ledger must have the details of individual accounts. The daily records kept in the journals are entered in the ledgers.
Every month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted in the ledger. The duty of the income statement or profit-and-loss statement is to give an analysis of the changes that have taken place in the ownership equity resulting due to the operations of the period. The balance sheet shows the financial position of the company at a particular day derived 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.
