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

The most typical question customers ask when buying a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and types available, it can be difficult for clients to make a choice between these technologies. It comes down to the fact that LCD projectors have superior image quality and colour accuracy. The following article will tell you why DLP projectors struggle with reproducing a similar level of image quality.

It’s like a set of blinds in your room for your bedroom window. By a twist of a rod you can have the shutters open or closed, depending on if you want to let light in or not. Such is exactly how an LCD projector behaves. Each pixel functions like an individual shutter on a set of blinds to either send 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 turned on to when the picture reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by dividing it into red, blue and green components, by three mirrors which send the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by shining each pixel on and off. The pixels are then combined in a glass prism to send the projector image. A point to understad about LCD projectors is that all three colours are delivered onto your wall simultaneously. The way a DLP projector operates is totally different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eye will then draw each coloured element of the image into the single complete image. Using LCD projectors, all colours are available all the time to offer the best brightness and superb colour accuracy. In DLP, only one colour is available at any given time, causing lower colour brightness and accuracy. Some DLP developers have included a white segment into the colour wheel to improve general brightness, but this then lessens colour accuracy.

I find in forums all the time that DLP has a higher contrast ratio and thus must be superior quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the technology is able to produce. DLP projectors do have high contrast specifications compared to the majority of LCD projectors. At a glance, this can seem to be an advantage, however, in truth, 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 wish to project includes moving images, DLP projection technology also has image marks, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because the colours are sent at the same time. DLP builders have come up with 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them almost impossible for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and remember when they taught you how various colours of light refract different amounts when directed through the same lens. The downside with DLP projectors is that they take the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Most of the time with a DLP projector, some yellow colour will come up above and an extra blue will show below an image of something as simple as a straight black line. In manufacturing LCD projectors can be adapted to minimize these effects on the projected image, because each colour is processed on isolated LCD panels.

The isolated veritable plus (excluding price) with choosing a DLP projector is its smaller size and weight. However, this is only relevant to mobility and needs to be traded off against the image advantages of LCD projectors. If the result of the picture quality is vital to you, then the decision is easy. Go with an LCD projector! LCD projectors will always create bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the first yacht was a pleasure craft used initially by royalty and later by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing 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 return to the English throne 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 then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting became popular among the rich and royalty, but after that period the trend did not last.

The first yacht association in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had much naval panoply and rigour. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imaginary enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, after joining with other societies, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered fashion on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yacht racing. The club at Cowes became the Royal Yachting Club, also at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for large stakes were held, and the society life was lovely. It came to be that the Royal Yachting Club boats increased 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 had power. Sailing was mostly for fun and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a benchmark of luxury and elegance for the later yachts in those waters from the late 19th century. The first continuing American yacht group, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The craft of sizeable yachts was originally largely affected by the success of America, which was designed by George Steers for a group led 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. Early yachts were not designed and crafted in the modern sense, with just a model used. Not until the latter half of the 19th century did what was known as naval architecture come into action. Not until the 1920s did the employment of the study of aerodynamics do for the craft of sails and rigging what such study had already done for hulls.

Because most of all sailboats were individually built, there was a need for handicapping boats as this was previous to the one-design class boats were built. Therefore, a rating rule came into being, which ended up in the International Rule, adopted in 1906 and amended in 1919. Today, one of the fastest flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to the same dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for such boats can be done on an even basis with no handicapping required. A perfect example is the standard International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

So long as yachting was done mostly for the royal and the rich, cost was no object, and the size of boats grew, in both length and weight. The promotion and popularity of smaller craft happened 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 journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of less sizeable craft. Following this in the 20th century, particularly after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, during which steam began to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in leisure yachts. Sizeable power yachts were furthered to a high standard, and long-distance cruising became a preferred activity of the well off. The first power yachts were paddle-wheel boats; those then gave way to yachts powered by the wholly submerged screw or propeller kind of propulsion. Like naval and merchant boats, auxiliaries possessing both sail and power were the yacht archetype for many years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were only power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the construction of large steam yachts. Notably within 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 at least 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service in World War II.

As bigger and more dependable internal-combustion engines were produced, many bigger craft were using them for power. The creation of the diesel engine, with heavy oil for fuel, progressed during World War I. During the decade after, big power-yacht creation flourished, climaxing in the Orion (1930) at 3,097 tons. From that period the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power yachts fell away in 1932, and the style after that was toward smaller, less expensive boats. Following World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting had become a widespread popular sport enjoyed by thousands of yachtsmen individually owning and upkeeping their own small recreational yachts. The number of yachts and yachtsmen increased steadily, not only in the traditional areas along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that places the same relative requirement on all taxpayers—i.e., where tax liability and income move in relative levels. A progressive tax is recognisable by a higher than proportional rise in the tax liability relative to the increase in income, and a regressive tax is characterized by a less than proportional rise in the relative burden. Thus, progressive taxes are thought of as removing inequalities in income distribution, but regressive taxes are believed to have the result of increasing these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, could become less so in the upper-income demographic—in particular if a taxpayer is allowed to lessen his tax base by claiming deductions or by taking some certain income aspects from his taxable income. Proportional tax rates which are applied to lower-income categories can also be more progressive if personal exemptions are claimed.

Income measured over the course of a given year might not necessarily offer the most accurate measure of taxpaying ability. For example, transitory increases in income can be saved, and during temporary declines in income a taxpayer could decide to provide for consumption by taking from savings. So, if taxation is regarded alongside “permanent income,” it should be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (save those on luxuries) tend to be regressive, because the spread of own income consumed or spent for specific goods lowers as the level of personal income is raised. Poll taxes (also known as head taxes), levied as a set amount per capita, clearly are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden lays for the most part on whether a national or a subnational (that is, provincial or state) tax is being determined.

In regarding the economic purposes of taxation, it is relevant to differentiate between various concepts of tax rates. The statutory rates include those specified in the legislation; often these are marginal rates, but sometimes they are median rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income is increased by one dollar. Hence, if tax burden increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax regulations often contain graduated marginal rates—i.e., rates that rise as income grows. Structured analysis of marginal tax rates are required to take into account provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than specified in the statutory rates. Since marginal rates display how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, as it may be reliant on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds 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 paid in taxation. The pattern of average rates is the one that is relevant 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 increase with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households can dampen these effects, allowing regressivity, as shown by average tax rates that decrease as income increases.

The Development of Data Projectors

The LCDs utilised for projection systems are typically small reflective or transmissive panels illuminated by a strong arc lamp source. A series of lenses expands the reflected or transmitted image then casts it on a screen. In front-projection systems the LCD is placed on the side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of more expense and capability can utilise three separated LCD panels, casting separate red, green, and blue images that combine to make a coloured image on the screen.

The increase in demand for film presentations has granted a growth in emphasis on the switching speed of liquid crystals. This has necessitated the development of items build with smectic liquid crystals, some of which possess a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most complex smectic device. In it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal contains optically active molecules, and a subtle consequence of the optical activity and the tilt of the molecules is the appearance 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 within the plane of the layers. Hence, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been produced for big passive-matrix presentations, but their expense and complex detail has impeded them from making any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some promise for use as elements in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be utilised 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 succession (around 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and then to a nontransmissive state for the blue period, having the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture items, the chair might be the most imperative. While most of the other items (apart from the bed) are designed to support objects, the chair supports the human form. The term chair must be looked upon here in the largest sense, from stool to throne to developed forms for example the bench and sofa, which might be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinuishable.

The social history of the chair is as stimulating as its history as art and craft. The chair is not simply a physical support and aesthetic piece; it historically was a signifier of social status. At the Medieval royal courts there were important distinctions between being led to a chair with arms, sitting on a chair with a back but without arms, and having to utilise a stool. From the last century, a director’s and/or manager’s chair has been regarded as an indicator of superior rank, like in democratic governments the speaker sits on a high-set platform.

In a furniture construction, the chair encompasses a range of various purposes. There are chairs structured to attend to man’s age and physical condition (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). During past times there were chairs for births (birth chairs); in the 20th century, there have been chairs to die in (the electric chair). We design chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated unique chairs for use in automobiles and aircraft. All of these chair kinds has been perfected to fit to different human uses. Because of its particular association with man, the chair exists to its full purpose only when utilised. Though it doesn’t make any difference to one’s appreciation of a cupboard or a chest of drawers whether there is anything inside or not, a chair is best seen and fairly tested with a person sitting in it, for chair and sitter complement the other. Thus the various limbs of a chair are given names likened to the names of a human shape: arms, legs, feet, back, and seat.

Because the obvious job of your chair is to support the body, its worth is tested basically by how completely it fulfills this practical use. Within the build of the chair, the builder is restricted within particular static legislation and principal measurements. Through these regulations, however, the chair designer has large freedom.

The history of the chair was an era of several thousand years. There are societies that made distinctive chair types, seen of the foremost endeavour in the arenas of skill and art. From such peoples, particular 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of expert design, are found from tombs. One of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs formed not unlike those of a particular animal, a curved seat, with a sloping back supported from vertical stretchers. From this a strong triangular construction was obtained. There was from our knowledge no significant differentiation in the structure of Egyptian thrones and chairs for typical peasantry. The general variation lies in the intricacy of ornamentation, in the evidence of pricier inlays. The Egyptian folding stool likely was manufactured for an easily stored seat for army soldiers. As a camp stool this chair stayed around til much later points. But the stool also then was created as the task of a ceremonial seat, its technical history as a folding stool neglected or forgotten. This can from today’s evidence be observed, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were in the form of folding stools but can not be folded as the seats were formed with wood. The plain structure of the folding stool, being of two frames that turn on metal bolts and bear a seat of leather or fabric set between them, can be seen but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of these is the folding stool, of ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not as any ancient specimen still in form but as found in a variety of pictorial objects. The archetype is the klismos placed on the Hegeso Stele at the Dipylon burial location by Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs are displayed. These creative legs were presumed to have been manufactured out of bent wood and were as such put under great pressure with the weight of the sitter. The joints joining the legs to the frame of the seat had to be therefore super stable and were plainly indicated.

The Romans emulated the Greek chair; designs of casts of seated Romans show evidence of a more heavyset and apparently kind of more crudely constructed klismos. Both features, the light and the heavy, were brought back in the Classicist time. The klismos style is known in French Empire styles, in English Regency, and in special kinds of marked individuality of Denmark and Sweden circa 1800.

China
The past of the chair in China isn’t able to be tracked as long as the history of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an undamaged folio of sketches and artworks has been preserved, with images of the interiors and outer parts of Chinese households and their furniture. Also preserved from the 16th century are a collection of chairs constructed of wood or lacquered wood, that possess an interesting resemblance to representations of previous chairs.

Just the same as in Egypt, there existed two particular chair designs in China: a chair with four legs and a folding stool. This four-legged chair is constructed both with and without arms although never missing a square seat and straight stiles (upright side supports) to support the back. In one type, however, the stiles were delicately curved over the arms in order to suit the form of the S-shaped back splat (the main upright of a chairback). The three areas are mortised on the yoke-like top rail. Despite that the style of this back splat exercised a foundation for English chairs of the Queen Anne period, wooden members that only to a particular ability stabilise corner joints (and then were loose as well) signify an element solely to Chinese chairs. The four legs are set through the seat frame, which finishes over the rounded staves. All the members are round in section or have rounded edges—acknowledging perhaps to the bamboo tradition. The seat is not comfortable and had on occasion a plaited bottom. These chairs required the sitter to stay stiff and upright; for if too much weight is forced on the back, the chair has a way of collapsing. In patriarchal Chinese homes of this epoch armchairs most likely were reserved for senior members of the family, for they were esteemed greatly.

The Chinese folding stool is understood to have travelled to China from the West. It does not vary much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is intricately held to the two legs of the stool by using a curved member, which is generally possessing metal mounts. From a Western point of view the overall effect of both these furniture forms is stylized. The construction and aesthetic elements are combined in a style that is all at once both naïve and refined. The patchwork appearance is an outcome of the fact that the individual members do not appear to have been fixed together with either glue or screws, but were mortised onto one another and fixed in position in the manner of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered style of chair is displayed in engravings of the interior of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair may also be found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not decided that the form actually was born in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of thin measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was produced in vast numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up along a wall. The style asserts itself by virtue of its harmonious proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, to say, as developed in Paris around 1750—disseminated over most of Europe and has been imitated or copied in the mid-20th century. The style owes the popularity to a combination of comfort and delicacy. The seat suits to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions are achieved between seat frame, legs, and back cover all the joints, which are constructed solidly on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of fairly thick density; but every member is deeply molded, all superfluous wood has been cut away, and more upmarket designs might be further embellished with very delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all upholstery on the seat, back, and armrests; crosshatched cane is sometimes used rather than upholstery.

English chairs in the 18th century were more variable in design than the French. The French touch for stylistic uniformity, which disseminated from the aristocratic circles in Paris and Versailles through most of France and became the favourite 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 reknowned 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 transactions of a business. Bookkeeping creates the numbers from which accounts are written but is a separate process, prior to accounting.

Fundamentally, bookkeeping finds two parts of information: (1) the current value, or equity, of an enterprise and (2) changes in value—profit or loss—taking place in the business over a given period.

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

Bits and pieces of financial and numerical recordkeeping can be uncovered for nearly every society with a commercial background. Records of trade contracts were discovered 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 progression of the enterprising republics of Italy, and manuals for bookkeeping were developed in the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial records a must-have. The past of bookkeeping, in fact, closely resembles the ancestry of commerce, industry, and government and, partially, helped shaping it. The international market of industrial and commercial activity needed higher sophisticate decision-making processes, which then needed more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislation became more significant and resulted in greater demand for information; business entities had to have information available 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 demand for bookkeeping for their own inner operations went up.

Although bookkeeping procedures can be extremely complex, it is all based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger contains the information of individual accounts. The daily records kept in the journals are written in the ledgers.

Every month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted in the ledger. The job of the income statement or profit-and-loss statement is to show an analysis of those changes that took place in the enterprise equity because of the operations of the period. The balance sheet provides the financial condition of the company at the particular point in time regarding 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 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.
