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

The most common question asked when buying a new projector for the home, office, or classroom is: do I take an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and models available, it can be confusing for consumers to choose between both technologies. The simple fact of the matter is that LCD projectors provide far superior image quality and colour accuracy. The next paragraph tells you why DLP projectors struggle with bringing up the same standard of image quality.

Imagine a set of blinds in your home on your bedroom window. By twisting a rod you can make the shutters open or closed, according to whether you want to let light in or not. And that is exactly how an LCD projector operates. Each pixel functions like an individual shutter on a set of blinds to either pass 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 operates to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the content reaches your screen is absolutely significant with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels form the elements of the image by shining each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. Something important to remember about LCD projectors is that all three colours are projected onto your wall at the same time. The way a DLP projector works is very different and even how an image appears is not the same. With DLP, white light from the lamp is projected through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of making 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 form the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into the complete image. With LCD projectors, all colours are available all the time to offer the best brightness and great colour accuracy. In DLP, just one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some designers have added a white segment into the colour wheel to improve all over brightness, but this further damages colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and thus must be better. 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 machine is capable of producing. DLP projectors do have high contrast specifications compared to most LCD projectors. At one glance, this seems to be an advantage, however, in real life, the true black level is determined by the ambient light in the room in which the projector is utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you want to bring to life includes moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector creates 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 displayed. LCD projectors do not have this problem because all colours are sent at the same time. DLP developers have come up with 3DLP solutions using 3 chips to solve the colour break up problem, but the price tag of these projectors make them hardly practical for the large part of businesses and consumers.

Another difference between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and remember how the different colours of light refract differing amounts when passing through the same lens. The problem with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in different ways. Generally with a DLP projector, an extra yellow colour will appear above and an extra blue will come up below something as simple as a lone black line. During manufacturing LCD projectors can be fixed to reduce these effects on the projected image, as each colour is projected on a separate LCD panels.

The only veritable advantage (excluding price) with buying a DLP projector is its smaller size and weight. However, this is only relevant for mobility and has to be traded off against the image superiority of LCD projectors. If resulting picture quality is crucial to you, then the choice is simple. Go for an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the early yacht was a pleasure craft used mostly by royalty and secondly by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration 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 then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting was found to be popular for the affluent and nobility, but after that point the habit did not last.

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

Yacht racing was first seen in some stipulated manner on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was then called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing fight, 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 sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British yachting. The association at Cowes became the Royal Yachting Club, also at the rise of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the social life was splendid. It came to be that the Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English held control. Sailing was largely for fun and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in the area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of sizeable yachts was first largely put upon by the victory 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. Earlier yachts were not designed and crafted in today’s sense, with only a model for an outline. Not until the second half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the use of the research of aerodynamics do for the craft of sails and rigging what it had already done for hulls.

Because most of all sailboats had been individually manufactured, there was a requirement for handicapping boats before the one-design class boats were designed. Therefore, a rating rule came into being, which is found in the International Rule, taken on in 1906 and revised in 1919. Today, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are created to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be had on an even keel with no handicapping required. A great example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting was an activity mostly for the aristocracy and the rich, money was no issue, and the size of boats increased, in both length and weight. The ascendancy and popularity of smaller boats happened in the later half of the 19th century from 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) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the seaworthiness of less sizeable yachts. Following this in the 20th century, notably after World War II, smaller racing and recreational craft became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, at which point steam was set to emulate sail power in public vessels, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal craft. Large power yachts were furthered to a high degree, and long-distance travel was a favoured pastime of the rich. The early power yachts were paddle-wheel boats; those then gave rise to boats powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries with both sail and power were the yacht fashion for many years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the large part were only power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a boom in the construction of large steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 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 was used in active service for World War II.

As larger and more reliable internal-combustion engines were produced, many bigger boats began using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced for World War I. In the decade after that, big power-yacht creation grew, hitting a climax in the Orion (1930) at 3,097 tons. In that period the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats declined in 1932, and the fashion after that was toward smaller, less costly craft. From World War II, a lot of small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a widespread beloved sport enjoyed by thousands of yachtsmen individually sailing and keeping their own small recreational craft. The popularity of yachts and sailors is increasing steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are categorized by the impact they have on the distribution of income and wealth. A proportional tax is a kind that applies the same relative liability on all taxpayers—i.e., when tax liability and income grow in relative proportion. A progressive tax is characterizable by a greater than proportional growth in the tax burden in regard to the rise in income, and a regressive tax is recognisable by a less than proportional increase in the comparative onus. So, progressive taxes are viewed as reducing the lack of equality in income distribution, whereas regressive taxes may have the effect of increasing these inequalities.

The taxes that are normally believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so within the upper-income class—particularly if a taxpayer is permitted to lower his tax base by nominating deductions or by taking particular income aspects from his taxable income. Proportional tax rates if applied to lower-income categories would also be more progressive if personal exemptions are claimed.

Income measured over the period of a year may not absolutely give the most accurate measure of taxpaying requirement. For example, transitory increases in income might be saved, and within temporary declines in income a taxpayer could opt to finance consumption by reducing savings. Ergo, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (with the exception of those on luxuries) are mostly regressive, because the portion of own income consumed or spent on specific goods decreases as the rate of personal income grows. Poll taxes (aka head taxes), nominated as a standard amount per capita, clearly 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 regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effects of taxation, it is important to differentiate between various concepts of tax rates. The statutory rates include those specified in law; often these are marginal rates, but in some cases they are average rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income rises by one dollar. Hence, if tax liability grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that rise as income grows. Careful analysis of marginal tax rates need to regard provisions apart from 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 greater than specified by the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the appropriate ones for assessing incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applicable to income from business and capital, since it may be reliant on factors such as 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 indicate the portion of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually rise with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households may swamp these effects, forcing regressivity, as indicated by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs built in projection systems are generally small reflective or transmissive panels illuminated by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image then casts it onto a screen. With front-projection systems the LCD is set on the same area of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of greater expense and capability might use three separated LCD panels, forming separate red, green, and blue images that combine to create a coloured image on the screen.

The growing need for visual displays has granted a special emphasis on the switching speed of liquid crystals. This has led to the creation of objects using smectic liquid crystals, some kinds of which give a faster 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 cast in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a subtle consequence of the optical activity and the slant of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Hence, there must be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark when one or more polarizers are employed.

SSFLC devices have been publicized for large passive-matrix presentations, but their high cost and complex nature has stopped them from making any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate response 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 speed (about 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods but then to a nontransmissive state during the blue period, with the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture needs, the chair might be the imperative one. While most of the other items (save the bed) are meant to support objects, the chair supports a human form. The term chair is used here in the widest sense, from stool to throne to developed chairs including the bench or sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly definitive.

The social history of the chair is as exciting as its history as an art and craft. The chair is not merely a physical support and/or an aesthetic creation; it can also be symbolic of social status. Within the historical royal courts there were important connotations between having a chair with arms, or a chair with a back but without arms, or having to squat on a stool. In the past century, a director’s or manager’s chair has become an identifier of superior rank, as well as in democratic government meeting the speaker sits on a high-set platform.

As a furniture form, the chair is used for a variety of different purposes. There are chairs created to attend to man’s age and physical abilities (the high chair, the wheelchair) and to connotate his status in society (the executive chair, the throne). From past days there were chairs for births (birth chairs); from the 20th century, there have been chairs to die in (the electric chair). There are chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed new chairs for automobiles and aircraft. All these chair shapes has been adapted to suit to evolving human desires. For its close link with man, the chair lives to its full advantage only when in employ. Whereas it doesn’t make any difference to one’s appreciation of a cupboard or a bureau if there are items inside or not, a chair is really seen best and judged with a person sitting in it, for chair and sitter suit one another. Thus the various parts of a chair were labeled like the parts of the human parts: arms, legs, feet, back, and seat.

Because the clear function of your chair is to support the body, its value is judged primarily on how completely it does measure up to this practical purpose. Within the structure of the chair, the designer is bound under the static rules and principal measurements. Inside these regulations, however, the chair maker has large freedom.

The history of the chair was an epoch of several thousand years. There is evidence of cultures that had made significant chair forms, seen of the topmost craft in the industries of technique and art. From 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of careful design, are found from tomb findings. First of them is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair has four legs structured similar to those of a chosen animal, a curved seat, leading to a sloping back supported by vertical stretchers. In this way a strong triangular design was crafted. There was to our understanding no notable difference from the structure of Egyptian thrones and chairs for regular populace. The general difference exists in the complexity of ornamentation, in the selection of pricey inlays. The Egyptian folding stool in all probability was crafted to be an easily stored seat for army. As a camp stool that kind persevered until much later points in time. But the stool then also took on the purpose of a ceremonial seat, its mechanical job as a folding stool ignored or forgotten. This can now be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but are not able to be folded as the seats were made with wood. The simple build of the folding stool, consisting of two frames that rotate on metal bolts and support a seat of leather or fabric held between them, also appeared but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this form is the folding stool, crafted from ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is seen not from any ancient object still extant but found in a large amount of pictorial items. The better known is the klismos seen on the Hegeso Stele at the Dipylon burial location outside Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those could be visible. These curving legs were thought to have been crafted of bent wood and were thus had a large amount of pressure from the weight of the sitter. The joints holding the legs to the frame of the seat would have been therefore very solid and were particularly drawn.

The Romans emulated the Greek chair; quite a few casts of seated Romans display evidence of a heavier and in appearance kind of crudely designed klismos. Both kinds, light and heavy, were seen again during the Classicist epoch. The klismos influence can be seen in French Empire design, in English Regency, and in some particular types of considerable uniqueness around Denmark and Sweden from 1800.

China
The past of the chair in China isn’t able to be followed as far back as the ancestry of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an undamaged collection of drawings and paintings has been protected, with images of the interior and outer parts of Chinese homes and the furniture. Preserved also from the 16th century are some chairs constructed from wood or lacquered wood, that hold an astonishing similarity to representations of ancient chairs.

As were the designs in Egypt, there existed two standard chair forms in China: a chair that had four legs and a folding stool. The four-legged chair is constructed both with or without arms however always having the square seat and straight stiles (upright side supports) to hold up the back. In one design, though, the stiles are marginally curved by the arms in order to conform to the form of the S-shaped back splat (the basic upright of its back). The three sections had been mortised onto the yoke-like top rail. Although the style of this back splat had an introduction for English chairs during the Queen Anne period, wooden members that only just to a restricted limit stabilise corner joints (and were loose as a result) represent a design exclusive to Chinese chairs. The four legs are set through the seat frame, which finishes upon the rounded staves. All the members are round in section or have rounded edges—a left over maybe to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited form. These chairs required of the sitter to be stiff and upright; for if too much pressure is exerted on the back, the chair has a tendency to collapse. In patriarchal Chinese houses of this period armchairs most likely were reserved only for older persons in the family, for they were respected greatly.

The Chinese folding stool is thought to have travelled to China from the West. It does not differ very much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is intricately affixed to the two legs of the stool with a curved member, which is usually designed with metal mounts. From a Western viewpoint the resultant effect of these furniture designs is stylized. The construction and aesthetic elements are combined in a manner that is both naïve and refined. The patchwork appearance is a result of the way that the individual items do not seem to have been fixed together with either glue or screws, but had been mortised into one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Works of art display a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between the layers, stitched to show up a pattern of small pads. The front board and a corresponding board from the back could be folded after unscrewing some small iron hooks. Thus the chair was a readily portable piece of furniture in traveling which, during the same period, granted the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced 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 kind of chair can also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not believed that the innovation actually was born in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slim shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in considerable numbers, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up by a wall. The form asserts itself by virtue of its shapely proportions and delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as developed in Paris around 1750—disseminated through most of Europe and was imitated or copied during the mid-20th century. The chair owes this popularity to a combination of relaxation and charm. The seat adheres to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are strongly constructed on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of fairly thick measurements; but all members are deeply molded, all extra wood has been taken away, and finer chairs can be further embellished with very delicate and decorative woodwork. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all upholstery on the seat, back, and armrests; crosshatched cane is sometimes used in place of upholstery.

English chairs from the 18th century were more differentiated in style than the French. The French manner for stylistic uniformity, which spread from the highest circles in Paris and Versailles within 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 well-known 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 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, indicate 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 transactions of a business. Bookkeeping provides the figures from which accounts are made but is a previous process, prior to accounting.

Fundamentally, bookkeeping finds two kinds of information: (1) the current value, or equity, of the entity and (2) the changes in value—profit or loss—taking position in the entity within a singular period.

Management officials, investors, and credit grantors all need to have such information: management in order to interpret the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to analyse the outcome of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to analyze the financial statements of an entity in judging whether to accept a loan.

Bits and pieces of financial and numerical record charts are uncovered for just about every nation with a commercial backbone. Records of business contracts have been found in the archaelogy of Babylon, and accounts for both farms and estates have been created in ancient Greece and Rome. The two-entry style of bookkeeping began with the progression of the business republics of Italy, and tutorials for bookkeeping were developed within the 15th century in several Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a paramount factor. The ancestry of bookkeeping, in fact, reflects closely the past of commerce, industry, and government and, in some part, assisted shaping it. The international revolution of industrial and commercial activity called for more cosmopolitan decision-making methodology, 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 important and resulted in higher demand for information; businesses had to show available information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the need for bookkeeping for their own operations became higher.

While bookkeeping methods can be very multifaceted, all are based on two types of books employed 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 record of individual accounts. The daily records kept in the journals are entered in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to display an analysis of any changes that occurred in the ownership equity because of the operations of the period. The balance sheet provides the financial condition of the business at a particular day 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 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.
