Projectors: LCD Verses DLP (The downfall of DLP technology)

The most typical question heard when purchasing a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two top projector imaging technologies. With so many company brands and models available, it can be difficult for clients to make a decision between those technologies. The simple fact of the matter is that LCD projectors have far better image quality and colour accuracy. The article below tells you why DLP projectors struggle with projecting a similar rate of image quality.

Think of a set of blinds in your home over your bedroom window. By a twist of a rod you can make the shutters open or closed, according to if you want to let light in or not. Such is exactly how an LCD projector operates. Each pixel operates like a unique shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point at which the projector turns on to when the image reaches your screen is absolutely significant to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 different 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 create the projector image. Something important to understad about LCD projectors is that all three colours are delivered onto your screen all at once. The way a DLP projector functions is very different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is processed through a rotating 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 displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then draw each coloured element of the image into a complete image. In LCD projectors, all colours are available all the time to create the highest brightness and spectacular colour accuracy. In DLP, just one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some DLP manufacturers have added a white segment for the colour wheel to improve all over brightness, but this also lessens colour accuracy.

I hear in forums all the time that DLP offers a higher contrast ratio and as such must be superior quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the technology is capable of producing. DLP projectors do provide high contrast specifications in comparison to a majority of LCD projectors. At one glance, this must be a benefit, however, in truth, the true black level is determined by the ambient light in the room while the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to bring to life requires moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this characteristic because all the colours are projected simultaneously. DLP builders have formed 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the expense of these projectors make them hardly practical for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Think back to high school science, and they taught you how various colours of light refract various amounts when projected through the same lens. The disadvantage with DLP projectors is that they utilise the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light at different levels. Most of the time with a DLP projector, a superfluous yellow colour will come up above and some extra blue will appear below an image containing something as simple as a single black line. During manufacturing LCD projectors can be set to remove these effects on the projected image, because each colour is processed on isolated LCD panels.

The sole veritable benefit (excluding price) with deciding on a DLP projector is its smaller total size and weight. However, this is only relevant in regard to transport and cannot be traded off against the image advantages of LCD projectors. If resulting picture quality is important to you, then the choice is easy. Go for an LCD projector! LCD projectors will always show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the initial yacht was a leisure craft used initially by royalty and secondly by the burghers in the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting became classy among the rich and royalty, but after that period the trend 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 association, and held great naval panoply and rigour. The closest thing to racing was the “chase,” when the “fleet” pursued an imaginary enemy. The club endured, largely as a social club, until 1765, and in 1828, when merging with other clubs, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated fashion on the Thames around the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group 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 continuing location of British yacht racing. The organisation at Cowes became the Royal Yachting Club, also at the accession of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for high stakes were held, and the club life was superlative. Ultimately Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English took power. 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 established a benchmark of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The craft of large yachts was initially largely put upon by the win of America, which was created by George Steers for a group headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. The first yachts were not designed and manufactured in a contemporary sense, with merely a model being used. Not until the second half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the employment of the science of aerodynamics do for the structure of sails and rigging what such study had done earlier for hulls.

Because nearly all sailboats were individually custom-built, there was a need for handicapping boats as this was before the one-design class boats were made. Therefore, a rating rule came into being, which resulted in the International Rule, adopted in 1906 and amended in 1919. In modern times, one of the fastest growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for those boats can be held on an even playing field with no handicapping necessary. A great example is the standard International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the aristocracy and the affluent, cost was no object, and the size of boats increased, in both length and weight. The rise and popularity of smaller boats occurred in the later half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small craft. Later in the 20th century, particularly after World War II, smaller racing and leisure boats became more popular, down to the dinghy, a favourite 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
Following the decade 1840–50, during which steam began to emulate sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly favoured in pleasure boats. Large power yachts were developed to a high standard, and long-distance travel was a fond pastime of the rich. The first power yachts were paddle-wheel boats; these then made way to boats powered by the fully submerged screw or propeller type of propulsion. Like naval and merchant craft, auxiliaries with both sail and power were the yacht standard for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of large steam yachts. In particular of 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, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As larger and more dependable internal-combustion engines were produced, many large yachts were using them for power. The creation of the diesel engine, with heavy oil for fuel, advanced from World War I. In the decade following that, bigger power-yacht building flourished, hitting a climax in the Orion (1930) at 3,097 tons. From that point the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power boats declined after 1932, and the fashion from then was toward smaller, less expensive craft. After World War II, a lot of small naval boats were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a globally loved activity enjoyed by thousands of yachtsmen individually sailing and maintaining their own small leisure boats. The number of yachts and owners has increased steadily, not only in the traditional places on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the impact they have on the placement of income and wealth. A proportional tax is one that places the same relative onus on every taxpayer—i.e., in the case where tax liability and income move in the same levels. A progressive tax is characterizable by a more than proportional increase in the tax burden in relation to the growth in income, and a regressive tax is characterizable by a less than proportional rise in the comparable burden. Thus, progressive taxes are regarded as removing a lack of equality in income distribution, but regressive taxes are found to increase these inequalities.

The taxes that are often considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, might become less so within the upper-income group—particularly if a taxpayer is allowed to lower his tax base by nominating deductions or by taking particular income aspects from his taxable income. Proportional tax rates that are applied to lower-income groups could also be more progressive if exemptions of a personal nature are made.

Income measured over the period of a year may not definitely provide the most appropriate measure of taxpaying status. For example, transitory growth in income can be saved, and during temporary declines in income a taxpayer could decide to finance consumption by reducing savings. So, if taxation is regarded along with “permanent income,” it will be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (excepting luxuries) are generally regressive, because the spread of one’s income consumed or spent on a specific good declines as the amount of personal income rises. Poll taxes (also called head taxes), calculated as a standard amount per capita, obviously are regressive.

It is complicated to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In analysing the economic purposes of taxation, it is essential to differentiate between differing ideas of tax rates. The statutory rates are specified in the law; usually these are marginal rates, but sometimes they are mean rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income rises by one dollar. Therefore, if tax liability grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislation usually contain graduated marginal rates—i.e., rates that increase as income increases. Structured analysis of marginal tax rates must regard 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 higher than specified within the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the important 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 be reliant 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 nothing under a consumption-based tax.

Average income tax rates show the part of total income that is paid in taxation. The pattern of average rates is the one that is necessary for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly grow with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received mostly by high-income households can dwarf these effects, forcing regressivity, as displayed by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs put in projection systems are most often small reflective or transmissive panels illuminated by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image and sends it onto a screen. For front-projection systems the LCD is located on the same area of the screen as the viewer, however in rear-projection systems the screen is illuminated from behind. Projectors of more expense and capacity can utilise three discrete LCD panels, forming separate red, green, and blue images that mesh to make a coloured image on the screen.

The growing requirement for visual presentations has granted a particular emphasis on the switching speed of liquid crystals. This has led to the development of objects using smectic liquid crystals, some kinds of which give a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most sophisticated smectic device. In it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and in the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal has optically active molecules, and a slight outcome of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, similar to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. Thus, there must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark when one or more polarizers are employed.

SSFLC devices have been marketed for large passive-matrix displays, but their expense and intricacy has stopped them from having any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as parts in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be used in time-sequential colour systems, in which highly expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in quick pulsing (about 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods but then to a nontransmissive state in the blue period, with the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture items, the chair may be the most important. While most of the other objects (except the bed) are intended to support objects, the chair supports a human form. The term chair must be used here in the larger sense, from stool to throne to developed chairs including the bench or sofa, which can be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly defined.

The social history of the chair is as interesting as its history as a creative craft. The chair is not merely a physical support and/or aesthetic item; it historically is semiotic of social rank. Within the Medieval royal courts there were social distinctions between being seated on a chair with arms, on a chair with a back but without arms, and having to use a stool. During the 20th century, the director’s and manager’s chair has been regarded as iconic of superior dignity, and in democratic parliaments the speaker sits on a higher floor.

In its furniture creation, the chair is utilised for a range of various forms. There are chairs designed to suit man’s age and physical abilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). Since past days there were chairs used for birth (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our modern lifestyle has designated special chairs for automobiles and aircraft. All of these chair forms have been changed to suit to differing human uses. From its unique association with man, the chair appears to its full significance only when used. Though it makes no difference to one’s appreciation of a cupboard or a dresser drawers if there are items inside or not, a chair is best seen and tested by a person sitting in it, because chair and sitter suit each other. Thus the different areas of a chair were named according to the elements of our human form: arms, legs, feet, back, and seat.

Because the original purpose of the chair is to support a body, its credit is valued basically from how suitably it does measure up to this practical function. Within the creation of the chair, the builder is limited by some static legislation and principal measurements. Within these limitations, however, the chair designer has large freedom.

The history of the chair lasts over an era of several thousand years. There is evidence of cultures that have created distinctive chair types, seen of the premier endeavour in the spheres of craft and art. Among these peoples, special mention must 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 masterful design, are a finding from tomb findings. One of these is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs crafted similar to those of some animal, a curved seat, with a sloping back supported above vertical stretchers. In this design a strong triangular structure was obtained. There seems to be no particular difference in the design of Egyptian thrones and chairs for typical citizens. The simple variation existed in the complexity of ornamentation, in the evidence of costly inlays. The Egyptian folding stool most probably was created for an easily portable seat for soldiers. As a camp stool this chair stayed around until much later days. But the stool then also was designed as the role of a ceremonial seat, its technical job as a folding stool simply forgotten. This can from today’s evidence be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were made in the form of folding stools but aren’t able to be folded as the seats were made out of wood. The plain make of the folding stool, made of two frames that rotate on metal bolts and bear a seat of leather or fabric fastened between them, was seen again somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this form is the folding stool, crafted from ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is known not with any ancient specimen still in form but as seen from a trove of pictorial evidence. The most well known is the klismos displayed on the Hegeso Stele at the Dipylon burial place 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 them can be displayed. These strange legs were considered to have been manufactured from bent wood and were likely to have been bore huge pressure from the weight of the sitter. The joints attaching the legs to the frame of the seat are therefore very stable and were clearly pointed out.

The Romans borrowed from the Greek style; some casts of seated Romans display chairs of a denser and which appear to be a slightly less delicately crafted klismos. Both features, the light and heavy, were seen again as part of the Classicist time. The klismos chair is evidenced in French Empire design, in English Regency, and in some special kinds of considerable iconicism around Denmark and Sweden from 1800.

China
The ancestry of the chair in China cannot be followed as long as chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed serial of drawings and paintings was preserved, with images of the insides and outside of Chinese buildings and the designs of furniture. Another preservation from the 16th century are a collection of chairs crafted from wood or lacquered wood, that bear an interesting resemblance to styles of ancient chairs.

As was the case in Egypt, there were two major chair forms in China: a chair of four legs and a folding stool. That chair is seen both with and without arms but always with the square seat and straight stiles (standing side supports) to give support to the back. In one kind, however, the stiles had been slightly curved by the arms so as to suit the form of the S-shaped back splat (the basic upright of the chairback). All three parts were mortised into the yoke-like top rail. While the design of the Chinese back splat later had a foundation for English chairs of the Queen Anne period, wooden pieces that only just to a particular extent embolden corner joints (and then are loose to top it off) are a signature solely to Chinese chairs. The four legs sit through the seat frame, which closes upon the rounded staves. Members are round in section or have rounded edges—acknowledging maybe to the bamboo tradition. The seat is unpleasant to sit in and might have had a plaited seat. These chairs demanded of the sitter to stay stiff and upright; for when too much pressure is forced on the back, the chair has a habit of collapsing. In patriarchal Chinese households of this epoch armchairs presumably were reserved only for the senior persons, for they were greatly respected.

The Chinese folding stool is presumed to have taken to China from the West. It is not dissimilar very much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is elegantly held to the two legs of the stool by a curved member, which is often designed with metal mounts. From a Western viewpoint the ultimate effect of these two furniture designs is stylized. The construction and decorative elements are combined in a way that is simultaneously naïve and refined. The pieced-together appearance is an upshot of the fact that the individual members do not seem to have been held together by either glue or screws, but were mortised into one another and fixed in place 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. Paintings show a design of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between, stitched to show up a pattern of small pads. The front board and a similar board in the back could be folded after unscrewing some small iron hooks. In this way the chair was an easily portable piece of furniture when traveling which, at the same period, possessed the status 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 rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair might also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not decided that the style actually originated in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was produced in impressive amounts, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of those chairs lined up against a wall. The design asserts itself by its shapely proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is, as developed in Paris around 1750—spread through most of Europe and has been imitated or copied in the mid-20th century. The design owes the popularity to a combination of leisure and elegance. The seat conforms to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions are found between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of rather thick dimensions; but each member is deeply molded, all extraneous wood has been taken away, and more expensive items would be further embellished with special delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for any upholstery on the seat, back, and armrests; canework is sometimes used instead of upholstery.

English chairs of the 18th century were more open in style than the French. The French manner for stylistic uniformity, which lead from the aristocratic 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
In the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, hint that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping grants the details from which accounts are made but is a different process, prior to accounting.

Basically, bookkeeping records two parts of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking position in the entity over a singular time period.

Management officials, investors, and credit grantors all require this kind of information: management in order to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the results of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to regard the financial statements of an entity in judging whether to give a loan.

Evidence of financial and numerical records have been seen for almost every group of people with a commercial background. Records of commercial contracts have been discovered in the remains of Babylon, and accounts for both farms and estates were kept in ancient Greece and Rome. The double-entry style of bookkeeping started with the furthering of the business republics of Italy, and tutorials for bookkeeping were developed within the 15th century in various Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a requirement. The past of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, partially, helped forming it. The worldwide market of industrial and commercial activity needed better sophisticate decision-making methods, which itself needed higher sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government regulation became more significant and resulted in even greater demand for information; business entities had to have information available to go with 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 their own inner departmental operations increased.

While bookkeeping methodology can be extremely 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 contains the records of individual accounts. The daily records from the journals are written in the ledgers.

Every month, generally, an income statement and a balance sheet are created from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of any changes that have taken place in the ownership equity from the transactions of the period. The balance sheet provides the financial condition of the enterprise at any particular point with regard to assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
