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

The most common question asked when purchasing a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many company brands and different types available, it can be difficult for customers to pick between both technologies. It comes down to the fact that LCD projectors provide far superior image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up a similar standard of image quality.

Visualise a set of blinds in your household covering your bedroom window. By pulling a rod you can make the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector works. Each pixel functions like a single shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point at which the projector turns on to when the image reaches your screen is ultimately significant in regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which send the coloured light to 3 individual LCD panels. The 3 LCD panels form the elements of the image by shining each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. A 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 functions is vastly different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming an image requires a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into the complete image. With LCD projectors, all colours are available all the time to offer high brightness and spectacular colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some designers have placed a white segment into the colour wheel to improve brightness overall, but this also lessens colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and thus must be better quality. For those unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is able to produce. DLP projectors do have high contrast specifications in comparison to the majority of LCD projectors. At one glance, this must be an advantage, however, in the real world, the true black level is determined by the ambient light in the room where the projector is used. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you plan to see requires moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change position between the time red, blue and green colours are shone. LCD projectors do not have this problem because the colours are delivered simultaneously. DLP builders have come up with 3DLP solutions using 3 chips to answer the colour break up issue, but the price tag of these projectors make them not practical for the majority of businesses and consumers.

Another point of difference between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and recall when they taught you how the various colours of light refract various amounts when passing through the same lens. The problem with DLP projectors is that they use 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 in different ways. Usually with a DLP projector, a superfluous yellow colour will come through above and a spill of blue will be projected below something as simple as a straight black line. In building LCD projectors can be set to take away these effects on the projected image, because each colour is refracted on a separate LCD panels.

The isolated true buy point (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to mobility and has to be traded off against the image plusses of LCD projectors. If overall picture quality is vital to you, then the choice is a no-brainer. Go for an LCD projector! LCD projectors will constantly produce 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 pleasure craft used initially by royalty and later by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private challenges. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, 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 for the rich and aristocracy, but after that time the trend did not last.

The first yacht club in the British Isles, the Water Club, was started around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with much naval panoply and gravity. The closest thing to a race was the “chase,” when the “fleet” pursued an imagined enemy. The club endured, largely 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 stipulated method on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it was called 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 group had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing setting of British racing. The society at Cowes became the Royal Yachting Club, also at the ascension of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing races for high bets 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 started with the Dutch in New York in the 17th century and went on when the English held control. Sailing was largely for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a minimum of luxury and elegance for the later yachts in those waters from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The craft of bigger yachts was originally greatly impacted by the victory of America, which was created by George Steers for a club led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. The first yachts were not designed and built in the modern sense, with just a model used. Not until the second half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the use of the research of aerodynamics do for the craft of sails and rigging what such science had already done for hulls.

Because nearly all sailboats were individually built, there came a need for handicapping boats as this was previous to the one-design class boats were made. Thus, a rating rule came into being, which is found in the International Rule, accepted in 1906 and amended in 1919. Today, one of the rapidly flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to single dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing those boats can be done on an even keel with no handicapping at all. A prime example is the generic International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the aristocracy and the rich, money was no issue, and the size of boats developed, in both length and weight. The promotion and popularity of smaller boats happened 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 journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of smaller craft. Thereafter in the 20th century, for the larger part after World War II, smaller racing and recreational craft became more common, down to the dinghy, a favoured 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, during which steam began to replace sail power in market vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in personal yachts. Bigger power yachts were developed to a high degree, and long-distance sailing was a favoured activity of the affluent. The early power yachts were paddle-wheel boats; these then gave rise to those powered by the fully submerged screw or propeller type of propulsion. Like naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for a number of years. By the later half of the 20th century, several yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the manufacture of large steam yachts. Conspicuous of 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 more than 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 during World War II.

As larger and more dependable internal-combustion engines were created, many big boats started using them for power. The establishment of the diesel engine, using heavy oil for fuel, advanced for World War I. From the decade following, big power-yacht creation flourished, reaching a climax 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 large power boats fell away in 1932, and the fashion thereafter was toward smaller, less pricey yachts. From World War II, a lot of small naval craft were bought by private owners for conversion to yachts. In the late 20th century, yachting has become a globally beloved competition enjoyed by thousands of yachtsmen personally owning and keeping their own small leisure craft. The number of yachts and owners is increasing steadily, not only in the traditional areas by the beach 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 one that imposes the same relative liability on every taxpayer—i.e., when tax liability and income grow in relative levels. A progressive tax is characterizable by a higher than proportional rise in the tax burden relative to the rise in income, and a regressive tax is recognisable by a less than proportional increase in the comparable burden. Therefore, progressive taxes are viewed as removing inequity in income distribution, whereas regressive taxes are seen to result in an increase these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so for the upper-income class—in particular if a taxpayer is able to lessen his tax base by nominating deductions or by removing some income elements from his taxable income. Proportional tax rates when applied to lower-income classes will also be more progressive if such personal exemptions are claimed.

Income measured over a given year might not definitely offer the best measure of taxpaying requirements. For example, transitory increases in income might be saved, and during temporary declines in income a taxpayer might elect to provide for consumption by decreasing savings. Therefore, if taxation is made comparable with “permanent income,” it can be less regressive (or more progressive) than when compared with annual income.

Sales taxes and excises (except those on luxuries) are mostly regressive, because the spread of personal income consumed or spent on a specific good lessens as the rate of personal income is raised. Poll taxes (aka head taxes), nominated as a standard amount per capita, patently are regressive.

It is difficult to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends crucially on whether a national or a subnational (that is, provincial or state) tax is being debated.

In considering the economic purposes of taxation, it is necessary to distinguish between several points of tax rates. The statutory rates will be nominated in the law; generally speaking 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 rises by one dollar. Therefore, if tax onus rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation commonly contain graduated marginal rates—i.e., rates that increase as income increases. Careful analysis of marginal tax rates need to review 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 rise in income, the marginal rate is 20 percentage points greater than indicated by the statutory rates. Since marginal rates display how after-tax income changes in response to changes in before-tax income, they are the relevant ones for assessing incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applicable to income from business and capital, since it may be reliant on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates signify the fraction of total income that is required 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 rises with income. Average income tax rates commonly rise with income, both because personal allowances are permitted for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received for the most part by high-income households could dampen these effects, forcing regressivity, as displayed by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs utilised for projection systems are generally small reflective or transmissive panels illuminated by a bright arc lamp source. A series of lenses expands the reflected or transmitted image and then displays it onto a screen. With front-projection systems the LCD is located on the side of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of greater expense and performance can use three separate LCD panels, creating separate red, green, and blue images that come together to create a coloured image on the screen.

The increase in need for visual displays has granted a growing emphasis on the switching speed of liquid crystals. This has led to the creation of items using 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 sophisticated smectic device. Inside it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and within the layers the molecules are slanted, as displayed in the figure. The host liquid crystal has optically active molecules, and a subtle turn up of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. Therefore, there must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been produced for bigger passive-matrix presentations, but their expensiveness and intricacy has impeded them from making any remarkable movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be used in time-sequential colour systems, in which costly colour filters are taken out for a coloured backlight that flashes red, green, and blue in rapid succession (around 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and to a nontransmissive state in the blue period, creating the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture objects, the chair might be the paramount one. While most of the other forms (apart from the bed) are created to support objects, the chair supports our human form. The term chair can be regarded here in the widest sense, from stool to throne to further chairs like a bench or sofa, which can be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly labeled.

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 object; it was also semiotic of social standing. In the historical royal courts there were clear differences between being seated on a chair with arms, on a chair with a back but without arms, or having to utilise a stool. In the last century, the director’s and/or manager’s chair has developed iconic of superior position, as well as in democratic governments the speaker sits on an elevated level.

In its furniture creation, the chair can be used for a variety of different models. There are chairs structured to attend to man’s age and physical form (the high chair, the wheelchair) and to connotate his standing in society (the executive chair, the throne). Since the olden days there were chairs to be born in (birth chairs); from the 20th century, there have been chairs used for ending life (the electric chair). We have chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has derived unique chairs for use in automobiles and aircraft. All of these chair forms has adapted to suit to changing human desires. Due to its significant relationship with man, the chair appears to its full importance only when in use. Though it is not relevant to one’s appreciation of a cupboard or a dresser drawers whether there might be things inside or not, a chair is really understood and regarded best by a person using it, for chair and sitter suit the other. Thus the different parts of the chair were labeled like the names of our human form: arms, legs, feet, back, and seat.

Because the elemental job of a chair is to support our human body, its credit is judged basically from how fully it does measure up to this practical role. In the creation of the chair, the chair maker is restricted under some static law and principal measurements. In these rules, however, the chair creator has extensive freedom.

The history of the chair lasted dates of several thousand years. There is evidence of peoples that had individual chair forms, expressive of the foremost work in the areas of handling and art. Among such societies, a mention should 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of expert scheme, are now a finding from tomb findings. The first one of the two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have had four legs structured as akin to those of a chosen animal, a curved seat, with a sloping back supported from vertical stretchers. In this design a solid triangular design was obtained. There was to our knowledge no particular difference in the structure of Egyptian thrones and chairs for common non-royals. The general change exists in the intricacy of its ornamentation, in the particulars of expensive inlays. The Egyptian folding stool likely was made to be an easily portable seat for officers. As a camp stool that kind continued for much later times. But the stool then also took on the purpose of a ceremonial seat, its technical function as a folding stool being forgotten. This can now be seen, 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 construction of folding stools but can’t be folded as the seats are made of wood. The easy manufacture of the folding stool, made of two frames that cycle on metal bolts and hold a seat of leather or fabric set between them, was seen again some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this form is the folding stool, of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is known not with any ancient fossil still around but as found in a variety of pictorial objects. The significant kind is the klismos posited on the Hegeso Stele at the Dipylon burial area in outer Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs would be seen. These unique legs were thought to have been executed of bent wood and were in that case subjected to extreme pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore extremely durable and were visibly drawn.

The Romans emulated the Greek chair; some statues of seated Romans display designs of a denser and in appearance rather less delicately constructed klismos. Both designs, the light or the heavy, were seen again within the Classicist period. The klismos influence is evidenced in French Empire styles, in English Regency, and in some special forms of notable individuality within Denmark and Sweden during 1800.

China
The progression of the chair in China is not able to be traced as far as chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged series of sketches and artworks has been protected, showing the inside and exterior of Chinese houses and the designs of furniture. Kept also from the 16th century are a collection of chairs constructed from wood or lacquered wood, that possess an astonishing similarity to representations of past chairs.

As in Egypt, there were two particular chair forms in China: a chair with four legs and a folding stool. The four-legged chair has been seen both with or without arms though always with a square seat and straight stiles (upright side supports) to support the back. In one style, however, the stiles were delicately curved above the arms in order to conform correctly to the form of the S-shaped back splat (the main upright of a back). Together, the three areas are mortised into the yoke-like top rail. Despite that the style of this back splat exercised a foundation for English chairs from the Queen Anne period, wooden items that would only to a restricted ability embolden corner joints (and are loose as a result) signify a signature exclusive to Chinese chairs. The four legs pass through the seat frame, which stops around the rounded staves. All the members are round in section or has rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is not comfortable and may have a plaited seat. These chairs required the sitter to stay stiff and upright; when too much pressure is placed on the back, the chair has a tendency to collapse. In patriarchal Chinese houses of this era armchairs probably were reserved for older persons, for they were given great esteem.

The Chinese folding stool is thought to have been brought to China from the West. It does not vary that much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is prettily affixed to the two legs of the stool by means of a curved member, which is often provided with metal mounts. From a Western viewpoint the ultimate effect of both of these furniture designs is stylized. The constructive and decorative elements are combined in a manner that is simultaneously naïve and refined. The piecemeal appearance is an upshot of the fact that the individual items do not appear to have been held together by means of either glue or screws, but were mortised on one another and held in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its name on the chair. Paintings project a design of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to bring up a pattern of tiny pads. The front board and a corresponding board in the back could be folded after loosening some small iron hooks. Thus the chair was an easily portable piece of furniture when traveling which, at the same era, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is found in engravings of the 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 kind of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not decided that the innovation actually was instigated in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in considerable quantities, as can be surmised from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up against a wall. The design 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 forms—that was, as brought out in Paris around 1750—disseminated through most of Europe and was imitated or copied in the mid-20th century. The design owes this popularity to a combination of comfort and delicacy. The seat suits to the human body and permits 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 over the armrests. Smooth transitions achieved between seat frame, legs, and back disguise 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 employ wood of rather thick density; but each member is deeply molded, all superfluous wood has been taken away, and finer chairs may be further embellished with intricately delicate and decorative woodwork. 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 in some cases used in place of upholstery.

English chairs from the 18th century were more open in style than the French. The French taste for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles within most of France and became the preference 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 reknowned 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 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, purport 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 function of a business. Bookkeeping creates the details from which accounts are written but is a separate process, prerequisite to accounting.

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

Management officials, investors, and credit grantors all demand this information: management so as to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to interpret the outcome of business operations and make decisions about buying, holding, and selling securities; and credit grantors to analyze the financial statements of an enterprise in deciding whether to allow a loan.

Traces of financial and numerical charts can be uncovered for just about every group of people with a commercial backbone. Records of trading contracts have been discovered in the archaelogical digs of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The dual-entry style of bookkeeping came up with the development of the business republics of Italy, and tutorial manuals for bookkeeping were developed within the 15th century in various Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial books a paramount factor. The ancestry of bookkeeping, in fact, reflects the past of commerce, industry, and government and, in part, helped to shape it. The global revolution of industrial and commercial activity demanded higher sophisticate decision-making methodology, which itself 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 detailed and resulted in greater demand for information; businesses had to provide information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the need for bookkeeping for their inner departmental operations became higher.

Although bookkeeping methodology can be very detailed, it is all based on two kinds of books employed in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so forth), and the ledger must have the records of individual accounts. The daily records kept in the journals are put in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are created 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 those changes that happen in the business equity resulting from the operations of the period. The balance sheet provides the financial situation of the company at any particular date taken from 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 produced 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.
