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

The common question asked when looking for a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two top projector imaging technologies. With so many business brands and models available, it can be overwhelming for the buyer to make a choice between both technologies. Ultimately LCD projectors have far better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with bringing up a similar grade of image quality.

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

How the light source is processed from when the projector is switched on to when the content reaches your screen is ultimately important in regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by separating it into red, blue and green components, by three mirrors which send the coloured light to 3 different LCD panels. The 3 LCD panels create the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. A significant point to realise about LCD projectors is that all three colours are directed onto your projector screen at the same time. The way a DLP projector works is vastly different and even the way an image shows up 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 approach to creating an image forms a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to construct the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eyes will then pull together each coloured element of the image into the whole image. With LCD projectors, all colours are available all the time to create high brightness and fantastic colour accuracy. In DLP, just one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some DLP designers have included a white segment into the colour wheel to improve all over brightness, but this further degrades colour accuracy.

I hear in forums all the time that DLP offers a higher contrast ratio and ergo must be superior quality. For those uncertain, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is capable of producing. DLP projectors do possess high contrast specifications as compared to a majority of LCD projectors. At a glance, this appears to be a plus, however, in reality, the true black level is determined by the ambient light in the room where the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you plan to bring to life has moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images keep changing between the time red, blue and green colours are shone. LCD projectors do not have this downside because every colour is delivered at once. DLP developers have formed 3DLP solutions using 3 chips to solve the colour break up error, but the cost of these projectors make them not practical for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and they taught you how the various colours of light refract different amounts when shone 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 at different levels. Usually with a DLP projector, some yellow colour will appear above and a superfluous blue will be projected below an image as simple as a single black line. In manufacturing LCD projectors can be adjusted to minimize these effects on the projected image, because each colour is processed on its own LCD panels.

The only real benefit (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant to transporting the device and must be traded off against the image superiority of LCD projectors. If resulting picture quality is crucial to you, then the decision is no-brainer. Choose an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the initial yacht became a pleasure craft used initially by royalty and later by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting became fashionable with the wealthy and aristocracy, but after that time the habit did not last.

The first yacht group in the British Isles, the Water Club, was instigated in about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with great naval panoply and formality. The closest thing to racing was the “chase,” in which the “fleet” pursued an imaginary enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, by conglomerating with other groups, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered method 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 monarchy in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yacht racing. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bets were held, and the club life was splendid. Eventually Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English gained power. Sailing was mostly for leisure and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a benchmark of luxury and elegance for the later yachts in those waters from the late 19th century. The first persisting American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The craft of sizeable yachts was first greatly affected by the win of America, which was drawn by George Steers for a association headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. Earlier yachts were not designed and built in a contemporary sense, with merely a model being used. Not until the later half of the 19th century did what was known as naval architecture come into action. Not until the 1920s did the use of the research of aerodynamics do for the structure of sails and rigging what such science had previously done for hulls.

Because almost all sailboats had to be individually built, there was a requirement for handicapping boats as this was previous to the one-design class boats were designed. Thus, a rating rule came into being, which is found in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the fastest blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are created to standard requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be had on an even keel with no handicapping at all. A great example is the uniform International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

As long as yachting belonged largely for the aristocracy and the wealthy, money was no issue, and the size of boats increased, in both length and weight. The ascendancy and popularity of smaller yachts occurred in the second half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of less sizeable boats. Following this in the 20th century, particularly after World War II, smaller racing and pleasure craft became more common, 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, in which steam began to take the place of sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in pleasure vessels. Sizeable power yachts were progressed to a high degree, and long-distance travel was a favoured occupation of the affluent. The first power yachts were paddle-wheel boats; these then made way to yachts powered by the fully submerged screw or propeller sort of propulsion. As well as naval and merchant boats, auxiliaries carrying both sail and power were the yacht archetype for several years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were solely power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the design of bigger steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was operated 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 saw active service during World War II.

As larger and more dependable internal-combustion engines were developed, many bigger craft began using them for power. The development of the diesel engine, employing heavy oil for fuel, was furthered for World War I. From the decade after that, big power-yacht manufacture blossomed, hitting a climax in the Orion (1930) at 3,097 tons. In that point the largest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power yachts lessened in 1932, and the trend from then was toward smaller, less pricey craft. After World War II, a lot of small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a widespread popular activity enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small pleasure craft. The popularity of craft and yachtsmen is increasing steadily, not only in the traditional locations along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is one that applies the same relative liability on all the taxpayers—i.e., when tax liability and income grow in relative levels. A progressive tax is recognisable by a more than proportional increase in the tax onus in regard to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the related liability. Hence, progressive taxes are viewed as reducing a lack of equality in income distribution, but regressive taxes are believed to have the result of increasing these inequalities.

The taxes that are generally regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, could become less so in the upper-income class—especially if a taxpayer is permitted to lower his tax base by nominating deductions or by removing particular income parts from his taxable income. Proportional tax rates when applied to lower-income classes could also be more progressive if personal exemptions are made.

Income measured over a given year may not necessarily offer the most accurate measure of taxpaying requirement. For example, transitory growth in income might be saved, and during temporary declines in income a taxpayer may opt to pay for consumption by reducing savings. Ergo, if taxation is held in comparison alongside “permanent income,” it can be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (save on luxuries) tend to be regressive, because the spread of individual income consumed or spent for specific goods lowers as the rate of personal income is raised. Poll taxes (also termed head taxes), calculated as a standard amount per capita, clearly are regressive.

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

In considering the economic purposes of taxation, it is important to differentiate between differing points of tax rates. The statutory rates will include those nominated in the law; generally speaking these are marginal rates, but for some cases they are mean rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income rises by one dollar. So, if tax onus 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 increase as income rises. Structured analysis of marginal tax rates should consider provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than indicated 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 complicated to understand the marginal effective tax rate applied to income from business and capital, because it may be dependant on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates determine the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are provided for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households could dampen these effects, forcing regressivity, as displayed by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs built for projection systems are most often small reflective or transmissive panels lit by a forceful arc lamp source. A series of lenses magnifies the reflected or transmitted image and then casts it onto a screen. For front-projection systems the LCD is located on the same side of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of greater cost and capability sometimes have three discrete LCD panels, forming separate red, green, and blue images that mesh to create a coloured picture on the screen.

The increase in desire for video displays has had a particular emphasis on the switching speed of liquid crystals. This has led to the manufacture of devices build with smectic liquid crystals, some types of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. Inside it the liquid crystal molecules are cast in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a tilt, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a subtle result of the optical activity and the angle of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. Hence, there has to be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and therefore 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 produced for large passive-matrix displays, but their expense and intricacy has stopped them from having any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as elements in projection systems or as viewfinders in digital cameras. Their fast response allows them to be used in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid succession (approximately 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods and then to a nontransmissive state for the blue period, creating the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture objects, the chair could be the imperative one. While the majority of other forms (except the bed) are created to support objects, the chair supports your human form. The term chair is meant to be looked upon here in the most general sense, from stool to throne to complex chairs such as the bench and sofa, which can be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently defined.

The social history of the chair is as exciting as its history as art and craft. The chair is not just a physical support or an aesthetic object; it was historically semiotic of social standing. At the historical royal courts there were clear distinctions between having a chair with arms, sitting on a chair with a back but without arms, or having to sit on a stool. From the past century, a director’s and manager’s chair has developed an indicator of superior position, like in democratic parliaments the speaker sits on an elevated level.

In a furniture creation, the chair can be employed for a range of variations. There are chairs designed to suit man’s age and physical form (the high chair, the wheelchair) and to indicate his standing in society (the executive chair, the throne). From historical days there were chairs for birthing (birth chairs); since the 20th century, there have been chairs for ending life (the electric chair). There are chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded, chairs on wheels, and chairs on runners.

Modern day living has developed particular chairs in automobiles and aircraft. Each and every one of these chair forms has been evolved to conform to changing human requirements. Because of its close relationship with man, the chair exists to its full importance only when in use. Although it does not make any difference to one’s appreciation of a cupboard or a set of drawers whether there are things inside or not, a chair is understood and evaluated by a person sitting in it, because chair and sitter complement the other. Thus the individual areas of a chair have been named corresponding to the parts of a human form: arms, legs, feet, back, and seat.

Because the principal function of your chair is to support your body, its worth is valued principally on how suitably it does fulfill this practical job. In the design of a chair, the designer is restricted under some static laws and principal measurements. Through these regulations, however, the chair creator has awesome freedom.

The history of the chair is an era of several thousand years. There existed societies that had made distinctive chair shapes, expressive of the foremost craft in the industries of technique and creativity. From these cultures, a note needs to be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of careful design, were found from tombs. The first one of these two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs structured akin to those of an animal, a curved seat, and leading to a sloping back supported above vertical stretchers. From this a durable triangular form was made. There appears to be no significant variation from the structure of Egyptian thrones and chairs for regular non-royals. The general difference lies in the level of ornamentation, in the evidence of pricey inlays. The Egyptian folding stool in all likelihood was made to be an easily stored seat for army officers. As a camp stool this form existed during much later days. But the stool also was made as the use of a ceremonial seat, its mechanical role as a folding stool being forgotten. This can now be found, 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 are made in the structure of folding stools but aren’t able to be folded because the seats were worked of wood. The simplistic structure of the folding stool, composed of two frames that spin on metal bolts and support a seat of leather or fabric fastened between them, then came up but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of those is the folding stool, made of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is found not in any ancient object still existing but from a trove of pictorial objects. The better known is the klismos drawn on the Hegeso Stele at the Dipylon burial ground near Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of them are visible. These strange legs were presumed to be executed in bent wood and were as such put under a large amount of pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore very stable and were overtly indicated.

The Romans adopted the Greek designs; existing casts of seated Romans display designs of a heavier and which appear to be a rather less intricately crafted klismos. Both designs, light or heavy, were revived as part of the Classicist era. The klismos design is known in French Empire furniture, in English Regency, and in special kinds of notable originality of Denmark and Sweden around 1800.

China
The ancestry of the chair in China cannot be tracked as long as the history of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed series of sketches and works of art has been preserved, showing the interiors and outside of Chinese houses and the furniture. Kept also since the 16th century are a trove of chairs made of wood or lacquered wood, that display an intriguing familiarity to designs of past chairs.

Just as in Egypt, there were two major chair forms in China: a chair of four legs and a folding stool. This four-legged chair can be seen both with and without arms although never without the square seat and straight stiles (standing side supports) to give support to the back. In one style, though, the stiles were delicately curved over the arms for the purpose of fit the angle of the S-shaped back splat (the centre upright of its chairback). Together, all three sections had been mortised into the yoke-like top rail. While the style of a back splat had an introduction for English chairs during the Queen Anne period, wooden pieces that just to a restricted capability reinforce corner joints (and furthermore are loose to top that off) indicate a design particular to Chinese chairs. The four legs pass through the seat frame, which closes over the rounded staves. Members are round in section or have rounded edges—referable perchance to the bamboo tradition. The seat is uncomfortable and might have had a plaited texture. These chairs demanded of the sitter to stay stiff and upright; when too much pressure is pushed on the back, the chair has a way of toppling over. In patriarchal Chinese houses of this epoch armchairs probably were reserved only for the senior persons, for they were respected greatly.

The Chinese folding stool is believed to have come to China from the West. It does not vary much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is delicately joined to the two legs of the stool with a curved member, which is usually designed with metal mounts. From a Western viewpoint the ultimate effect of both furniture designs is stylized. The structure and decoration elements are combined in a way that is all at once both naïve and refined. The patched up appearance is an upshot of the fact that the individual members do not look to have been held together by either glue or screws, but are mortised into one another and fixed in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Paintings display a style of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to show up a pattern of little pads. The front board and a related board at the back could be folded after loosening some little iron hooks. Thus the chair was a readily portable piece of furniture while traveling which, in the same time, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be evidenced in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair is also found in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not determined that the style actually was born in The Netherlands. Usually, the legs of the chair will be smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was manufactured in large numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up against a wall. The form asserts itself with 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 of styles—that is, as brought out in Paris around 1750—disseminated through most of Europe and has been imitated or copied into the mid-20th century. The style owes the popularity to a combination of comfort and delicacy. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions are found between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of fairly thick dimensions; but all the members are deeply molded, all extraneous wood has been taken away, and finer items would be further embellished with very delicate and decorative engravings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for the upholstery on the seat, back, and armrests; cane is in some cases used rather than upholstery.

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

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

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

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

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

What is Bookkeeping?

Bookkeeping is the charting of the money values of the operation of a business. Bookkeeping grants the information from which accounts are prepared but is a different process, prior to accounting.

Essentially, bookkeeping records two parts of information: (1) the current value, or equity, of the entity and (2) the changes in value—profit or loss—taking place in the enterprise from a singular time.

Management officials, investors, and credit grantors all need to have such information: management to analyse the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshots of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an enterprise in judging whether to grant a loan.

Bits and pieces of financial and numerical recordkeeping are seen for just about every nation with a commercial backbone. Records of trading contracts were discovered in the ruins of Babylon, and accounts for both farms and estates have been archived in ancient Greece and Rome. The two-entry style of bookkeeping started with the development of the enterprising republics of Italy, and manuals for bookkeeping were developed in the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial books a must-have. The history of bookkeeping, in fact, closely resembles the past of commerce, industry, and government and, in some part, assisted forming it. The international revolution of industrial and commercial activity called for greater professional decision-making procedures, which in its turn demanded more sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more detailed and resulted in greater requirement for information; business firms had to show information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for departmental operations became larger.

Although bookkeeping methods can be rather complex, all are based on two styles of books used in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger contains the record of individual accounts. The daily records from the journals are written in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are created from the trial balance posted from the ledger. The job of the income statement or profit-and-loss statement is to give an analysis of the changes that have occurred in the enterprise equity because of the events of the period. The balance sheet shows the financial condition of the business at the particular day in terms of 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 resulted in 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.
