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

The common question heard when acquiring a new projector for the home, office, or classroom is: will I take an LCD projector or a DLP projector? LCD, standing 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 different models available, it can be overwhelming for clients to decide between those technologies. The fact is that LCD projectors give better image quality and colour accuracy. The article below will tell you why DLP projectors struggle with bringing up an equal standard of image quality.

Think of 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 whether you want to let light in or not. And that is exactly how an LCD projector works. Each pixel operates like its own shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector turns on to when the picture reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels form 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 point to realise about LCD projectors is that all three colours are projected onto your screen at once. The way a DLP projector operates is vastly different and even the final product of how an image appears is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of making an image casts a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s vision will then draw each coloured element of the image into the single whole image. With LCD projectors, all colours are available all the time to offer the highest brightness and fantastic colour accuracy. In DLP, only one colour is available at once, causing lower colour brightness and accuracy. Some manufacturers have put a white segment into the colour wheel to improve overall brightness, but this goes and detracts from colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and thus must be better. For those who are unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is capable of producing. DLP projectors do have high contrast specifications as compared to most LCD projectors. At a glance, this can seem to be a benefit, however, in real life, the true black level is determined by the ambient light in the room where the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you want to bring to life requires moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most typical artifact that a DLP projector forms with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because the colours are projected with the others. DLP builders have created 3DLP solutions using 3 chips to fix the colour break up problem, but the expense of these projectors make them not practical for most businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and remember when they taught you how different colours of light refract various amounts when projected through the same lens. The downside with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in different ways. Usually with a DLP projector, some yellow colour will appear above and some blue will come through below an image as simple as a lone black line. During manufacturing LCD projectors can be fixed to take away these effects on the projected image, as each colour is refracted on isolated LCD panels.

The only real advantage (excluding price) with choosing a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to portability and needs to be traded off against the image superiority of LCD projectors. If the result of the picture quality is vital to you, then the solution is simple. Go with an LCD projector! LCD projectors will definitely create bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the early yacht had been a leisure craft used mostly by royalty and secondly by the burghers on the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation 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, sovereign 1685–88), ordered for 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 was found to be classy for the rich and royalty, but after that period 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 group, and had great naval panoply and formality. The closest thing to a race was the “chase,” in which the “fleet” pursued a fictional enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, after merging with other organisations, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized fashion on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started 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 continued site of British yacht racing. The organisation 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 tests for large stakes were held, and the social life was superlative. Eventually Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English had power. Sailing was mostly for leisure and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht association, 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
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The design of sizeable yachts was originally heavily put upon by the victory of America, which was drawn by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its victory at Cowes in 1851. The first yachts were not designed and manufactured in a contemporary sense, with just a model for an outline. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the use of the science of aerodynamics do for the craft of sails and rigging what such study had done earlier for hulls.

Because almost all sailboats had to be individually manufactured, there was a requirement for handicapping boats before the one-design class boats were built. Therefore, a rating rule was decreed, which ended up in the International Rule, adopted in 1906 and revised in 1919. In the present day, one of the fastest growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard specifications 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 basis with no handicapping at all. A prime example is the generic International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

As long as yachting was an activity mostly for the aristocracy and the wealthy, money was no issue, and the size of boats developed, in both length and weight. The ascendancy and popularity of smaller yachts occurred in the latter 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 demonstrated the value of small boats. Following this in the 20th century, particularly after World War II, smaller racing and leisure yachts 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
Following the decade 1840–50, in which steam was set to emulate sail power in commercial craft, the steam engine, and later the internal-combustion engine, were favoured increasingly in pleasure vessels. Sizeable power yachts were furthered to a high degree, and long-distance sailing was a preferred activity of the affluent. The first power yachts were paddle-wheel boats; those then gave way to those powered by the completely submerged screw or propeller type of propulsion. Like naval and merchant yachts, auxiliaries possessing both sail and power were the yacht fashion for several years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were only power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the design of more sizeable 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 sailed by a crew of over 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 in World War II.

As bigger and better quality internal-combustion engines were developed, many large yachts were using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced for World War I. In the decade that followed, bigger power-yacht creation blossomed, reaching a climax in the Orion (1930) at 3,097 tons. In that point the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of bigger power craft lessened after 1932, and the trend thereafter was in preference of smaller, less costly yachts. After World War II, a lot of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting had become a internationally popular sport enjoyed by thousands of yachtsmen who are actually manning and maintaining their own small recreational craft. The amount of boats and yachtsmen has increased steadily, not only in the traditional locations along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the effect they have on the placement of income and wealth. A proportional tax is the kind of tax that puts the same relative onus on all the taxpayers—i.e., when tax liability and income move in the same scale. A progressive tax is characterizable by a greater than proportional growth in the tax onus relative to the rise in income, and a regressive tax is recognisable by a less than proportional growth in the comparable burden. Thus, progressive taxes are viewed as taking away a lack of equality in income distribution, whereas regressive taxes are believed to result in an increase these inequalities.

The taxes that are normally believed to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, could become less so within the upper-income demographic—particularly if a taxpayer is allowed to lessen his tax base by declaring deductions or by excluding some particular income parts from his taxable income. Proportional tax rates that are applied to lower-income demographics would also be more progressive if such personal exemptions are claimed.

Income measured over the period of a year does not necessarily offer the most suitable measure of taxpaying ability. For example, transitory rises in income can be saved, and during temporary declines in income a taxpayer could choose to provide for consumption by reducing savings. Therefore, if taxation is regarded with “permanent income,” it can be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (save those on luxuries) are mostly regressive, because the dissemination of own income consumed or spent for specific goods declines as the amount of personal income increases. Poll taxes (also called head taxes), calculated as a fixed amount per capita, obviously are regressive.

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

In considering the economic purposes of taxation, it is important to distinguish between various points of tax rates. The statutory rates will include those specified in the legislation; usually these are marginal rates, but for some cases they are mean rates. Marginal income tax rates note the fraction of incremental income that is taken by taxation when income is increased by one dollar. Ergo, if tax onus rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that rise as income rises. Structured 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) falls by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points greater than nominated within 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 appropriate ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate applied to income from business and capital, as it may depend on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates show the portion of total income that is paid in taxation. The pattern of average rates is the one that is relevant for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are allowed for the taxpayer and dependents and also due to that marginal tax rates are graduated; conversely, preferential treatment of income received mostly by high-income households may dwarf these effects, allowing regressivity, as signified by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs utilised in projection systems are usually small reflective or transmissive panels lit up by a powerful arc lamp source. A number of lenses enlarges the reflected or transmitted image then sends it onto a screen. In front-projection systems the LCD is placed on the same area of the screen as the viewer, while in rear-projection systems the screen is lit up from behind. Projectors of higher expense and capability might be found with three separated LCD panels, reflecting separate red, green, and blue images that combine to create a coloured display on the screen.

The growing desire for video presentations has put a growing emphasis on the switching speed of liquid crystals. This has required the development of objects using smectic liquid crystals, certain ones of which emit a better 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 differentiated by one or two micrometres, and throughout the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a slight outcome of the optical activity and the shape of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. So, there is a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark if one or more polarizers are used.

SSFLC devices have been publicized for bigger passive-matrix presentations, but their expense and complex nature has impeded them from enjoying any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate responding allows them to be utilised in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in rapid pace (approximately 100 cycles a second). For example, the liquid crystal may be switched to a transmissive state between the red and green periods but to a nontransmissive state during the blue period, creating the result 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 paramount. While the majority of other items (except the bed) are intended to support objects, the chair supports our human form. The term chair can be used here in the wider sense, from stool to throne to further makes like the bench and sofa, which may be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently labeled.

The social history of the chair is as stimulating as its history as a creative art. The chair is not just a physical support and/or an aesthetic creation; it is historically a symbol of social standing. In the past royal courts there were important distinctions between possessing a chair with arms, sitting on a chair with a back but without arms, or having to sit on a stool. During the recent century, a director’s and manager’s chair has been regarded as a symbol of superior position, and in democratic governments the speaker sits on a raised level.

As its furniture form, the chair is utilised for a wealth of various purposes. There are chairs structured to suit man’s age and physical capabilities (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). During the past there were chairs for births (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). We make chairs with one, two, three, and/or 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.

Our contemporary lifestyle has derived unique chairs for use in automobiles and aircraft. Each and every one of these chair forms has been perfected to match to evolving human requirements. Because of its significant connection with man, the chair exists to its full meaning only when in employ. Though it is irrelevant to one’s appreciation of a cupboard or a bureau if there might be anything inside or not, a chair is seen best and fairly regarded by a person sitting in it, because chair and sitter suit each other. Thus the various limbs of a chair are given labels likened to the areas of a human parts: arms, legs, feet, back, and seat.

Because the clear work of a chair is to support our body, its value is tested principally on how fully it measures up to this practical use. In the creation of a chair, the carpenter is restricted within certain static regulation and principal measurements. In these boundaries, however, the chair designer has extensive freedom.

The history of the chair lasts over a period of several thousand years. There is evidence of cultures that made iconic chair forms, expressions of the leading object in the spheres of technique and creativity. In such peoples, a mention can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of expert craft, are seen from tomb findings. The first of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs designed like those of some animal, a curved seat, and leading to a sloping back supported by vertical stretchers. From this a durable triangular structure was made. There was in our understanding no significant variation from the construction of Egyptian thrones and chairs for common peasantry. The only difference lied in the intricacy of its ornamentation, in the evidence of more valuable inlays. The Egyptian folding stool in all likelihood was created to be an easily packed seat for soldiers. As a camp stool this stool persisted until much later points in time. But the stool also then existed in the character of a ceremonial seat, its mechanical function as a folding stool simply forgotten. This can today be seen, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were in the structure of folding stools but cannot be folded as the seats were created with wood. The simplistic make of the folding stool, composed of two frames that rotate on metal bolts and support a seat of leather or fabric secured between them, also appeared but some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this kind is the folding stool, crafted out of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not from any ancient specimen still in form but in a variety of pictorial material. The better known is the klismos drawn on the Hegeso Stele at the Dipylon burial area outside Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, only two of these legs would be visible. These strange legs were considered to have been crafted from bent wood and were therefore had to bear extreme pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat are therefore very strong and were plainly pointed out.

The Romans embued the Greek design; designs of models of seated Romans show designs of a denser and which appear to be a somewhat less intricately built klismos. Both features, the light and the heavy, were revived in the Classicist time. The klismos style can be evidenced in French Empire styles, in English Regency, and in some particular forms of profound individuality in Denmark and Sweden around 1800.

China
The history of the chair in China can not be followed as well as the ancestry of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed folio of images and works of art was protected, detailing the interiors and outside of Chinese homes and their furniture. Another preservation from the 16th century are some chairs crafted from wood or lacquered wood, that show an interesting likeness to pictures of older chairs.

Same as in Egypt, there existed two iconic chair designs in China: a chair that had four legs and a folding stool. This chair was seen both with and without arms though always with the square seat and straight stiles (vertical side supports) to hold up the back. In one image, it must be said, the stiles had been delicately curved on top of the arms to fit the structure of the S-shaped back splat (the basic upright of a chairback). Together, the three sections are mortised in the yoke-like top rail. While the idea of the Chinese back splat had an influence on English chairs of the Queen Anne period, wooden pieces that only to a particular capability embolden corner joints (and furthermore were loose into the bargain) indicate an element signatory to Chinese chairs. The four legs pass through the seat frame, which stops upon the rounded staves. Each member is round in section or have rounded edges—references perchance to the bamboo tradition. The seat is unpleasant to sit in and may have a plaited bottom. These chairs required of the sitter to be stiff and upright; for if too much weight is placed on the back, the chair has a way of collapsing. In patriarchal Chinese houses of this period armchairs most likely were reserved only for the senior family members, for they were respected greatly.

The Chinese folding stool is believed to have travelled to China from the West. It is akin so very much from the Egyptian and Scandinavian folding stools, but it has a dissimilarity in that the top rail is delicately fixed to the two legs of the stool by use of a curved member, which is more often than not possessing metal mounts. From a Western point of view the overall effect of these two furniture items is stylized. The manufacture and decorative issues are combined in a manner that is at the same time naïve and refined. The patchwork appearance is a result of the fact that the individual items do not appear to have been affixed by means of either glue or screws, but had been mortised into one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its signature on the chair. Artworks project a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between, stitched to bring out a pattern of small pads. The front board and a similar board at the back could be folded after unscrewing some little iron hooks. Therefore the chair was an easily portable piece of furniture when traveling which, during the same time, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is evidenced in engravings of the inside of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair can also be seen in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not decided that the design actually was born in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slender shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in vast numbers, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of such chairs lined up along a wall. The style asserts itself by its harmonious proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is, as created in Paris around 1750—spread over most of Europe and was imitated or copied into the mid-20th century. The design owes its popularity to a combination of leisure and elegance. The seat adheres to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are solidly constructed on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them use wood of quite thick dimensions; but every member is deeply molded, all extra wood has been taken away, and more expensive chairs can be further embellished with intricately delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all of the upholstery on the seat, back, and armrests; crosshatched cane is sometimes used as an alternative to upholstery.

English chairs of the 18th century were more variable in design than the French. The French taste for stylistic uniformity, which disseminated from the royal circles in Paris and Versailles over most of France and became the favourite 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 popular and was widely distributed throughout the world.

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

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

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

What is Bookkeeping?

Bookkeeping is the charting of the money values of the transactions of a business. Bookkeeping grants the numbers from which accounts are prepared but is a different process, prerequisite to accounting.

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

Management officials, investors, and credit grantors all require this information: management to interpret the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to analyze the financial statements of a business in finding whether to grant a loan.

Bits and pieces of financial and numerical record charts can be seen for nearly every nation with a commercial history. Records of business contracts have been uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been archived in ancient Greece and Rome. The double-entry way of bookkeeping came with the progression of the business republics of Italy, and instruction manuals for bookkeeping were produced during the 15th century in many Italian cities.

Within the late 18th and early 19th centuries, the Industrial Revolution gave a significant stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a paramount factor. The history of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, in part, assisted to form it. The international revolution of industrial and commercial activity needed greater professional decision-making procedures, which itself required greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislature became more significant and resulted in even greater requirement for information; firms had to show available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the requirement for bookkeeping for their inner departmental operations increased.

Although bookkeeping methods can be very detailed, 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 so forth), and the ledger has the details of individual accounts. The daily records kept in the journals are entered in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are made from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of the changes that happen in the ownership equity as a result of the transactions of the period. The balance sheet displays the financial position of the corporation at any particular day 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.
