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

The common question heard when acquiring a new projector for the home, office, or classroom is: should I purchase an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many brands and different models available, it can be overwhelming for consumers to decide between these technologies. The fact is that LCD projectors provide far better image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up a comparable rate of image quality.

It’s like a set of blinds in your household covering your bedroom window. By pulling a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. Such is exactly how an LCD projector operates. Each pixel functions 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 professionals like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the picture reaches your screen is absolutely significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. A point to understad about LCD projectors is that all three colours are sent onto your wall at the same time. The way a DLP projector operates is very different and even the way an image looks 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 approach to forming an image creates 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 sent in sequence on the screen, one colour at a time. The viewer’s vision will then draw each coloured element of the image into the single complete image. From LCD projectors, all colours are available all the time to offer the highest brightness and superb colour accuracy. In DLP, only one colour is available at once, resulting in lower colour brightness and accuracy. Some developers have put a white segment for the colour wheel to improve all over brightness, but this further degrades colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and therefore must be superior quality. For those 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 technology is able to produce. DLP projectors do offer high contrast specifications compared to a majority of LCD projectors. At one glance, this can seem to be an advantage, however, in truth, the true black level is determined by the ambient light in the room while the projector is in use. Do not be tricked by contrast specifications on websites and in brochures.

When the content you are trying to bring to life includes moving images, DLP projection technology also has image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change between the time red, blue and green colours are pulled up. LCD projectors do not have this downside because all the colours are processed simultaneously. DLP manufacturers have developed 3DLP solutions using 3 chips to solve the colour break up problem, but the cost of these projectors make them hardly practical for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and recall when they taught you how different colours of light refract different amounts when passing 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 different and refract light in a different way. Usually with a DLP projector, a superfluous yellow colour will be projected above and some extra blue will be projected below an image containing something as simple as a lone black line. While being built LCD projectors can be set to minimize these effects on the projected image, as each colour is directed on a separate LCD panels.

The one veritable plus (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant with regard to mobility and must be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is crucial to you, then the decision is a no-brainer. Choose an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht became a pleasure craft used initially by royalty and then by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private challenges. 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) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, 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 wager. Yachting was found to be popular for the wealthy and nobility, but after that point the fashion did not last.

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

Yacht racing was first seen in some stipulated method on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to the throne in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht society 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 continued location of British yacht racing. The club at Cowes became the Royal Yachting Club, again at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing matches for high bets were held, and the society life was wonderful. Eventually Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English gained dominance. Sailing was for the most part for leisure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first enduring American yacht club, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The craft of bigger yachts was first largely affected by the success of America, which was created by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. Early yachts were not designed and built in today’s sense, with just a model being used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what such study had previously done for hulls.

Because nearly all sailboats were individually built, there came a need for handicapping boats previous to the one-design class boats were designed. Thus, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and amended in 1919. In the present day, one of the fastest growing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to single dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for those boats can be had on an even playing field with no handicapping required. A great example is the standard International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

For the time that yachting belonged primarily for the nobility and the affluent, money was no object, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller yachts 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 trip around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of less sizeable boats. Later in the 20th century, notably after World War II, smaller racing and recreational yachts became more popular, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam was set to replace sail power in public vessels, the steam engine, and later the internal-combustion engine, were used increasingly in leisure craft. Sizeable power yachts were furthered to a high standard, and long-distance travel turned into a preferred occupation of the affluent. The first power yachts were paddle-wheel boats; those then gave rise to yachts powered by the completely submerged screw or propeller sort of propulsion. As well as naval and merchant boats, auxiliaries carrying both sail and power were the yacht standard for several years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the large part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the construction of bigger 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 over 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 during World War II.

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

The manufacture of larger power craft fell away after 1932, and the trend thereafter was in preference of smaller, less costly yachts. Following World War II, many small naval boats were traded by private owners for conversion to yachts. By the late 20th century, yachting has become a internationally popular sport enjoyed by thousands of yachtsmen personally sailing and maintaining their own small leisure craft. The number of boats and yachtsmen increased steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the placement of income and wealth. A proportional tax is one that places the same relative burden on all taxpayers—i.e., where tax liability and income increase in the same proportion. A progressive tax is characterizable by a more than proportional rise in the tax onus in relation to the increase in income, and a regressive tax is recognisable by a less than proportional increase in the related liability. Ergo, progressive taxes are regarded as removing inequalities in income distribution, while regressive taxes might increase these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, may become less so in the upper-income group—especially if a taxpayer is allowed to reduce his tax base by declaring deductions or by taking particular income components from his taxable income. Proportional tax rates that are applied to lower-income classes would also be more progressive if personal exemptions are made.

Income measured over the course of a given year does not definitely come up with the best measure of taxpaying ability. For example, transitory rises in income could be saved, and within temporary declines in income a taxpayer could decide to provide for consumption by decreasing savings. So, if taxation is made comparable along with “permanent income,” it can be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (save luxuries) are generally regressive, because the share of one’s income consumed or spent for specific goods lessens as the rate of personal income is raised. Poll taxes (also known as head taxes), nominated as a fixed amount per capita, obviously are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic purpose of taxation, it is necessary to differentiate between various ideas of tax rates. The statutory rates will be dictated in the legislation; 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 increases by one dollar. Therefore, if tax onus rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that grow as income increases. Heavy analysis of marginal tax rates need to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate to apply to income from business and capital, since it may depend on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates determine the part of total income that is paid 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 grows with income. Average income tax rates commonly rise with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households might swamp these effects, producing regressivity, as shown by average tax rates that decline as income increases.

The Development of Data Projectors

The LCDs put in projection systems are usually small reflective or transmissive panels illuminated by a powerful arc lamp source. A series 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 side of the screen as the viewer, but in rear-projection systems the screen is illuminated from behind. Projectors of higher cost and capacity can utilise three separated LCD panels, casting separate red, green, and blue images that come together to reflect a coloured image on the screen.

The increasing requirement for visual displays has granted a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items build with smectic liquid crystals, some types of which give a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most sophisticated smectic device. In it the liquid crystal molecules are managed in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and in the layers the molecules are on a slant, as displayed in the figure. The host liquid crystal holds optically active molecules, and a minor result of the optical activity and the angle of the molecules is the appearance 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 within the plane of the layers. Therefore, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The resultant change in optical properties can effect a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been publicized for bigger passive-matrix displays, but their high cost and complex nature has hindered them from creating any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as parts in projection systems or as viewfinders in digital cameras. Their immediate response allows them to be utilised in time-sequential colour systems, in which dear colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid pulsing (approx 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state in the red and green periods but then to a nontransmissive state during the blue period, displaying the upshot that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture objects, the chair may be the primary one. While most other forms (save for the bed) are devised to support objects, the chair supports the human form. The term chair is meant to be looked upon here in the largest sense, from stool to throne to complex chairs including a bench or sofa, which may be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinguished.

The social history of the chair is as curious as its history as an art and craft. The chair is not just a physical support and an aesthetic piece of art; it was also a signifier of social standing. At the historical royal courts there were clear signifiers between sitting on a chair with arms, on a chair with a back but no arms, or worse having to cope with a stool. During the last century, the director’s and/or manager’s chair has been a symbol of superior standing, and even in democratic government debate the speaker sits on an elevated level.

In a furniture form, the chair ranges from a variety of various models. There are chairs structured to attend to man’s age and physical capabilities (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). From historical times there were chairs to be born in (birth chairs); during the 20th century, there have been chairs used for ending life (the electric chair). We make chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has derived new chairs for automobiles and aircraft. All of these chair forms has been evolved to conform to growing human uses. From its significant link with man, the chair appears to its full importance only when in use. Though it is not relevant to one’s appreciation of a cupboard or a chest of drawers if there might be things inside or not, a chair is really seen and regarded best with a person using it, for chair and sitter complement each other. Thus the individual elements of a chair have been given labels according to the limbs of the human parts: arms, legs, feet, back, and seat.

Because the original role of a chair is to support a human body, its worth is judged basically for how fully it does fulfill this practical purpose. Within the manufacture of a chair, the chair maker is restricted in particular static law and principal measurements. Through these boundaries, however, the chair maker has marvellous freedom.

The history of the chair covers dates of several thousand years. There are peoples that had individual chair forms, seen of the principal task in the areas of handling and creativity. Among these civilisations, special note 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of skilled design, were found from discoveries made in tombs. The first one of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have four legs designed as akin to those of some animal, a curved seat, and a sloping back supported above vertical stretchers. In this design a stable triangular design was obtained. There was apparently no noteworthy change in the creation of Egyptian thrones and chairs for typical citizens. The simple difference exists in the level of ornamentation, in the evidence of costly inlays. The Egyptian folding stool in all likelihood was created as an easily packed seat for army soldiers. As a camp stool that type persisted til much later periods. But the stool then also played the purpose of a ceremonial seat, its original function as a folding stool simply forgotten. This can from evidence be observed, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the form of folding stools but can’t be folded as the seats were formed out of wood. The easy build of the folding stool, being of two frames that cycle on metal bolts and have a seat of leather or fabric held between them, reappears but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of those is the folding stool, crafted out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not as any ancient object still existing but in a variety of pictorial items. The best known is the klismos seen on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs are shown. These unique legs were presumably manufactured of bent wood and were likely to have been needed to bear a large amount of pressure under the weight of the sitter. The joints holding the legs to the frame of the seat are therefore super solid and were particularly drawn.

The Romans borrowed from the Greek design; evidence of models of seated Romans show evidence of a heavier and apparently kind of crudely built klismos. Both features, light or heavy, were brought back within the Classicist period. The klismos influence can be evidenced in French Empire styles, in English Regency, and in some types of marked originality in Denmark and Sweden circa 1800.

China
The history of the chair in China isn’t able to be traced as far back as the ancestry of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed serial of sketches and paintings has been kept, with images of the inside and exterior of Chinese buildings and the designs of furniture. Another preservation of the 16th century are some chairs constructed from wood or lacquered wood, that bear an amazing resemblance to images of ancient chairs.

Same as in Egypt, there existed two fundamental chair designs in China: a chair that had four legs and a folding stool. That chair is seen both with and without arms though never without its square seat and straight stiles (straight side supports) to give support to the back. In one type, however, the stiles were lightly curved on top of the arms in order to conform correctly to the shape of the S-shaped back splat (the centre upright of the back). The three areas had been mortised on the yoke-like top rail. Though the style of the Chinese back splat later had a foundation for English chairs in the Queen Anne period, wooden members that merely to a particular capability stabilise corner joints (and furthermore are loose in the result) signify a feature signatory to Chinese chairs. The four legs pass through the seat frame, which stops over the rounded staves. All the members are round in section or is given rounded edges—referable maybe to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited form. These chairs needed the sitter to stay stiff and upright; for if too much pressure is placed on the back, the chair has a tendency to collapse. In patriarchal Chinese houses of this era armchairs most likely were kept for the senior individuals in the family, for they were given great esteem.

The Chinese folding stool is understood to have been brought to China from the West. It is not dissimilar much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is intricately joined to the two legs of the stool with a curved member, which is more often than not provided with metal mounts. From a Western understanding the ultimate effect of both of these furniture items is stylized. The manufacture and aesthetic aspects are combined in a style that is at the same time naïve and refined. The pieced-together appearance is a result of the way that the individual items do not appear to have been held together by means of either glue or screws, but are mortised with one another and locked into place in the manner 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 design of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to bring out a pattern of small pads. The front board and a related board in the back could be folded after unscrewing some tiny iron hooks. Thus the chair was a readily portable piece of furniture in traveling which, at the same era, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is displayed in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this design of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the innovation actually started in The Netherlands. Typically, the legs of the chair are smooth, round in section, and of slim shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in vast numbers, as surmisable from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up against a wall. The style asserts itself by its shapely proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, as created in Paris around 1750—disseminated over most of Europe and was imitated or copied during the mid-20th century. The chair owes such popularity to a combination of leisure and delicacy. The seat conforms to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back conceal all the joints, which are stable, constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those are made from wood of relatively thick measurements; but all members are deeply molded, all superfluous wood has been taken away, and more expensive designs might be further embellished with special delicate and decorative woodwork. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used rather than upholstery.

English chairs of the 18th century were more differentiated in form than the French. The French taste for stylistic uniformity, which came from the royal circles in Paris and Versailles within most of France and became the favourite in large 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, purport 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 provides the details from which accounts are made but is a distinct process, prerequisite to accounting.

Essentially, bookkeeping finds two types of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking position in the enterprise during a singular time.

Management officials, investors, and credit grantors all need this kind of information: management so as to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an enterprise in assessing whether to accept a loan.

Evidence of financial and numerical charts are seen for nearly every nation with a commercial history. Records of commercial contracts have been found in the archaelogy of Babylon, and accounts for both farms and estates were kept in ancient Greece and Rome. The double-entry method of bookkeeping started with the development of the business republics of Italy, and instruction books for bookkeeping were produced within the 15th century in many 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 perfect financial records a must-have. The ancestry of bookkeeping, in fact, reflects the past of commerce, industry, and government and, partially, assisted to form it. The global expansion of industrial and commercial activity demanded more cosmopolitan decision-making processes, which then called for greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more detailed and resulted in even greater need for information; businesses 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 become larger, and the requirement for bookkeeping for their inner operations became higher.

Although bookkeeping methodology can be rather multifaceted, all are based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and such), and the ledger should have the information of individual accounts. The daily records kept in the journals are entered in the ledgers.

At the end of each month, generally, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The purpose of the income statement or profit-and-loss statement is to display an analysis of any changes that have occurred in the ownership equity from the transactions of the period. The balance sheet gives the financial condition of the entity at a particular point in time derived from 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 yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

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

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

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

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

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