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

The most typical question asked when purchasing a new projector for the home, office, or classroom is: would I buy an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most popular projector imaging technologies. With so many business brands and different models available, it can be difficult for the buyer to pick between the two technologies. The simple fact of the matter is that LCD projectors offer far better image quality and colour accuracy. The article below will explain why DLP projectors struggle with creating the same standard of image quality.

Visualise a set of blinds in your house over your bedroom window. By twisting a rod you can have the shutters open or closed, according to whether you want to let light in or not. That is exactly how an LCD projector operates. Each pixel operates like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the picture reaches your screen is absolutely significant for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to send the projector image. A significant point to realise about LCD projectors is that all three colours are directed onto your screen at the same time. The way a DLP projector runs is widely different and even the produced image appears is not the same. With DLP, white light from the lamp is directed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of projecting an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to produce 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 draw each coloured element of the image into the complete image. From LCD projectors, all colours are available all the time to form top brightness and great colour accuracy. In DLP, only one colour is available at once, and so causing lower colour brightness and accuracy. Some developers have included a white segment for the colour wheel to improve brightness overall, but this also lessens colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and ergo must be better. For those who do not know, 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 projector is able to produce. DLP projectors do offer high contrast specifications compared to most LCD projectors. At a glance, this must be a plus, however, in truth, the true black level is determined by the ambient light in the room while the projector is in use. Do not be tricked by contrast specifications on websites and in brochures.

When the content you plan to project needs moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because all colours are delivered simultaneously. DLP builders have created 3DLP solutions using 3 chips to answer the colour break up error, but the price of these projectors make them almost impossible for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Think back to high school science, and they taught you how various colours of light refract differing amounts when projected through the same lens. The disadvantage 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 different and refract light differently. Often with a DLP projector, a spill of yellow colour will show above and an extra blue will show below an image of something as simple as a lone black line. In manufacturing LCD projectors can be fixed to take away these effects on the projected image, as each colour is directed on a separate LCD panels.

The only actual plus (excluding price) with picking a DLP projector is its smaller total size and weight. However, this is only relevant for transporting the device and must be traded off against the image superiority of LCD projectors. If overall picture quality is important to you, then the solution is easy. Go for an LCD projector! LCD projectors will always create bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the first yacht had been a leisure craft used first by royalty and secondly by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam sent him 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), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting became classy with the affluent and nobility, but after that point the trend did not last.

The first yacht club in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and had great naval panoply and rigour. The closest thing to racing was the “chase,” for which the “fleet” pursued a fictional enemy. The club went on, largely as a social club, until 1765, and in 1828, by merging with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing site of British yacht racing. The society at Cowes became the Royal Yachting Club, also at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for great stakes were held, and the club life was splendid. It came to be that the Royal Yachting Club boats grew in size to bigger than 350 tons.

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

Kinds of sailboats
The Early sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the latter half of the 19th century. The design of sizeable yachts was initially largely put upon by the success of America, which was created by George Steers for a syndicate headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. The first yachts were not designed and crafted in today’s sense, with merely a model being used. Not until the latter half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the use of the study of aerodynamics do for the structure of sails and rigging what science had previously done for hulls.

Because most of all sailboats had been individually manufactured, there arose a need for handicapping boats as this was previous to the one-design class boats were designed. Hence, a rating rule came into being, which ended up in the International Rule, adopted in 1906 and amended in 1919. Today, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are built to standard requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between such boats can be had on an even playing field with no handicapping necessary. A prime example is the uniform International America’s Cup Class adopted for participants in the 1992 America’s Cup race.

As long as yachting was done mostly for the nobility and the wealthy, cost was no problem, and the size of boats increased, in both length and weight. The rise and desire of smaller boats 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 trip around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of small yachts. Later in the 20th century, particularly after World War II, smaller racing and recreational boats became commonplace, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, at which point steam started to take the place of sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure vessels. Bigger power yachts were developed to a high element, and long-distance travel became a favoured pastime of the rich. The early power yachts were paddle-wheel boats; they then gave rise to those powered by the fully submerged screw or propeller kind of propulsion. As in the case of naval and merchant craft, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the construction of bigger steam yachts. Conspicuous within these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of at least 150. The Mayflower, bought 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 dependable internal-combustion engines were created, many large craft began using them for power. The establishment of the diesel engine, employing heavy oil for fuel, progressed during World War I. During the decade after that, big power-yacht manufacture grew, hitting a climax in the Orion (1930) at 3,097 tons. During that period the biggest auxiliary yacht manufactured 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 trend from then was in preference of smaller, less expensive 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 had become a internationally beloved sport enjoyed by thousands of yachtsmen individually manning and upkeeping their own small recreational boats. The popularity of craft and sailors increased steadily, not only in the traditional places along the seacoasts 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 the kind that imposes the same relative onus on all the taxpayers—i.e., where tax liability and income move in equal proportion. A progressive tax is recognised by a more than proportional increase in the tax onus relative to the growth in income, and a regressive tax is characterizable by a less than proportional rise in the relative burden. So, progressive taxes are regarded as removing inequity in income distribution, while regressive taxes are found to cause an increase in these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, can become less so within the upper-income demographic—particularly if a taxpayer is permitted to lessen his tax base by nominating deductions or by leaving out some particular income aspects from his taxable income. Proportional tax rates when applied to lower-income classes could also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the course of a given year does not definitely provide the most accurate measure of taxpaying requirements. For example, transitory rises in income may be saved, and within temporary declines in income a taxpayer might decide to finance consumption by reducing savings. Therefore, if taxation is compared along with “permanent income,” it should be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (except luxuries) are mostly regressive, because the share of own income consumed or spent on a specific good declines as the amount of personal income increases. Poll taxes (aka head taxes), levied as a set amount per capita, patently are regressive.

It is complicated to classify 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 dictating who bears the tax burden is dependant crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic purpose of taxation, it is essential to distinguish between differing ideas of tax rates. The statutory rates are those nominated in legislature; generally these are marginal rates, but in some cases they are average rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income rises by one dollar. Ergo, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax statutes generally contain graduated marginal rates—i.e., rates that increase as income increases. Careful analysis of marginal tax rates need to regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the relevant ones for assessing incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate to apply to income from business and capital, because it may rely on such factors 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 signify the percentage of total income that is required in taxation. The pattern of average rates is the one that is necessary for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are allowed for the taxpayer and dependents and also because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households could dwarf these effects, forcing regressivity, as displayed by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs put in projection systems are generally small reflective or transmissive panels lit up by a strong arc lamp source. A series of lenses enlarges the reflected or transmitted image then casts it on the screen. For front-projection systems the LCD is set on the same side of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of greater cost and capacity sometimes use three distinct LCD panels, casting separate red, green, and blue images that combine to reflect a coloured picture on the screen.

The growth in desire for video presentations has placed a growing emphasis on the switching speed of liquid crystals. This has led to the manufacture of objects using smectic liquid crystals, particular types of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed 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 in the layers the molecules are on a tilt, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a subtle turn up of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, similar to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Hence, there is a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly partnered 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 commercialized for large passive-matrix presentations, but their expensiveness and intricacy has stopped them from having any significant effect 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 employed in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick succession (approximately 100 cycles in a second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods but to a nontransmissive state during the blue period, displaying the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture forms, the chair may be the primary one. While the majority of other pieces (except the bed) are meant to support objects, the chair supports your human form. The term chair was said here in the wider sense, from stool to throne to complex items including a bench or sofa, which can be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously defined.

The social history of the chair is as exciting as its history as a creative craft. The chair is not merely a physical support and/or aesthetic piece; it was historically an indicator of social ranking. In the old royal courts there were plain distinctions between being seated on a chair with arms, or a chair with a back but no arms, or having to use a stool. From the last century, a director’s or manager’s chair has become an identifier of superior status, and even in democratic governments the speaker sits on a raised platform.

In its furniture construction, the chair is employed for a wealth of different forms. There are chairs structured to attend to man’s age and physical condition (the high chair, the wheelchair) and to indicate his position in society (the executive chair, the throne). From historical days there were chairs used for birth (birth chairs); from the 20th century, there have been chairs to die in (the electric chair). We have chairs with one, two, three, and 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.

Contemporary lifestyle has designated new chairs for automobiles and aircraft. Each and every one of these chair shapes have changed to conform to changing human needs. From its particular link with man, the chair lives to its full advantage only when in employ. Although it is not relevant to one’s appreciation of a cupboard or a bureau if there might be items inside or not, a chair is understood and fairly regarded by a person sitting in it, for chair and sitter need the other. Thus the various areas of the chair have been named according to the areas of the human form: arms, legs, feet, back, and seat.

Because the basic function of a chair is to support our human body, its worth is evaluated firstly on how well it measures up to this practical function. Within the creation of a chair, the chair maker is bound by particular static laws and principal measurements. In these rules, however, the chair designer has extensive freedom.

The history of the chair covered an era of several thousand years. There existed peoples that made distinctive chair shapes, as seen of the premier object in the arenas of skill and creativity. From these such societies, a mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of expert design, are today a finding from tomb discoveries. The first 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 not unlike those of a designated animal, a curved seat, and leading to a sloping back supported by vertical stretchers. From this design a solid triangular construction was created. There appears to be no marked variation in the construction of Egyptian thrones and chairs for common populace. The simple variation existed in the complexity of ornamentation, in the evidence of expensive inlays. The Egyptian folding stool probably was manufactured as an easily carried seat for soldiers. As a camp stool this type existed for much later points. But the stool then also played the character of a ceremonial seat, its mechanical function as a folding stool neglected or forgotten. This can from evidence be observed, 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 constructed in the structure of folding stools but are not able to be folded because the seats are worked out of wood. The simple construction of the folding stool, consisting of two frames that spin on metal bolts and support a seat of leather or fabric fastened between them, was seen again but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of those is the folding stool, of ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is found not as any ancient specimen still existing but found in a wealth of pictorial items. The archetype is the klismos placed on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of which were visible. These creative legs were understood to have been executed out of bent wood and were thus had to bear huge pressure under the weight of the sitter. The joints joining the legs to the frame of the seat would have been therefore super durable and were visibly pointed out.

The Romans embued the Greek style; a number of casts of seated Romans show examples of a more heavyset and are a somewhat more crudely crafted klismos. Both types, the light or the heavy, were revived during the Classicist period. The klismos design is known in French Empire styles, in English Regency, and in some special kinds of considerable originality around Denmark and Sweden around 1800.

China
The history of the chair in China isn’t able to be tracked as well as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an undamaged series of sketches and works of art was protected, showing the interiors and exteriors of Chinese houses and their furniture. Preserved also from the 16th century are a collection of chairs made from wood or lacquered wood, that possess an interesting resemblance to images of older chairs.

Just as in Egypt, there existed two fundamental chair designs in China: a chair that had four legs and a folding stool. This four-legged chair was found both with or without arms though never missing the square seat and straight stiles (upright side supports) to support the back. In one type, it must be said, the stiles could be lightly curved on top of the arms in order to sit correctly with the structure of the S-shaped back splat (the basic upright of its back). The three sections are mortised on the yoke-like top rail. Despite that the style of the back splat had an influence on English chairs during the Queen Anne period, wooden pieces that would only to a restricted capability reinforce corner joints (and then were loose to top it off) indicate a design exclusive to Chinese chairs. The four legs pass through the seat frame, which ends upon the rounded staves. All the members are round in section or has rounded edges—an acknowledgement maybe to the bamboo tradition. The seat is unpleasant to sit in and might have had a plaited seat. These chairs required the sitter to hold themselves stiff and upright; for if too much pressure is exerted on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this epoch armchairs probably were kept for elderly individuals, for they were greatly respected.

The Chinese folding stool is thought to have taken to China from the West. It is akin much from the Egyptian or Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is prettily joined to the two legs of the stool by use of a curved member, which is usually provided with metal mounts. From a Western understanding the resulting effect of these two furniture styles is stylized. The construction and decorative aspects are combined in a style that is all at once both naïve and refined. The patchwork appearance is an upshot of the fact that the individual items do not appear to have been constructed with either glue or screws, but have been mortised onto one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its signature on the chair. Works of art project 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, stitched to produce a pattern of tiny pads. The front board and a corresponding board in the back could be folded after unscrewing some little iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, during the same time, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be seen in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair might also be found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not held that the design actually originated in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was produced in large quantities, 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 by a wall. The style asserts itself by its elegant proportions and fine 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 to say, as brought out in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The chair owes this popularity to a combination of leisure and charm. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are constructed solidly on craftsmanlike principles despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of quite thick dimensions; but all the members are deeply molded, all extra wood has been cut away, and more upmarket designs might be further embellished with highly delicate and decorative engravings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for the upholstery on the seat, back, and armrests; cane is occasionally used instead of upholstery.

English chairs of the 18th century were more open in style than the French. The French preference for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles over most of France and was popular 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 commonly 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 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, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping grants the information from which accounts are prepared but is a different process, preliminary to accounting.

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

Management officials, investors, and credit grantors all need this kind of information: management to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to analyze the financial statements of a business in judging whether to give a loan.

Pieces of financial and numerical records have been seen for almost every civilization with a commercial background. Records of commercial contracts were discovered in the ruins of Babylon, and accounts for both farms and estates have been archived in ancient Greece and Rome. The double-entry method of bookkeeping came up with the progression of the entrepeneurial republics of Italy, and instruction books for bookkeeping were created in the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial bookkeeping a necessity. The ancestry of bookkeeping, in fact, closely resembles the past of commerce, industry, and government and, in some part, assisted in forming it. The international spread of industrial and commercial activity demanded greater sophisticate decision-making methodology, which in turn demanded more sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more significant and resulted in greater demand for information; enterprises had to provide 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 their inner departmental operations became higher.

Though bookkeeping methods can be very detailed, it is all based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger contains the details of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The purpose of the income statement or profit-and-loss statement is to display an analysis of the changes that happen in the business equity because of the transactions of the period. The balance sheet displays the financial situation of the corporation at the particular date 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 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 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.
