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

The most typical question heard when purchasing a new projector for the home, office, or classroom is: would I buy an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two top projector imaging technologies. With so many company brands and different types available, it can be difficult for clients to pick between these technologies. It comes down to the fact that LCD projectors offer far better image quality and colour accuracy. The article below tells you why DLP projectors struggle with creating an equal standard of image quality.

Imagine a set of blinds in your home over your bedroom window. By twisting a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. Such is exactly how an LCD projector functions. Each pixel works like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed 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 turns on to when the content reaches your screen is ultimately important to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 separate LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then projected in a glass prism to create the projector image. Something important to know about LCD projectors is that all three colours are directed onto your screen simultaneously. The way a DLP projector functions is vastly different and even how an image comes out is not the same. With DLP, white light from the lamp is projected through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to projecting an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into a single whole image. Using LCD projectors, all colours are available all the time to deliver the best brightness and superb colour accuracy. In DLP, only one colour is available at a time, causing lower colour brightness and accuracy. Some DLP designers have placed a white segment for the colour wheel to improve overall brightness, but this goes and lessens colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and therefore must be superior quality. For those who are uncertain, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the technology is able to produce. DLP projectors do have high contrast specifications compared to a majority of LCD projectors. At a glance, this appears to be a benefit, however, in truth, the true black level is determined by the ambient light in the room where the projector is used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you want to project requires moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most commonplace artifact that a DLP projector forms with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are projected. LCD projectors do not have this characteristic because the colours are processed simultaneously. DLP builders have created 3DLP solutions using 3 chips to fix the colour break up issue, but the cost of these projectors make them hardly practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how different colours of light refract different amounts when directed through the same lens. The problem with DLP projectors is that they utilise the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light differently. Generally with a DLP projector, a spill of yellow colour will show above and a spill of blue will show below an image as simple as a straight black line. In manufacturing LCD projectors can be adjusted to reduce these effects on the projected image, because each colour is processed on isolated LCD panels.

The isolated real advantage (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant to mobility and must be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is vital to you, then the choice is simple. Take an LCD projector! LCD projectors will constantly make bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the initial yacht was a pleasure craft used first by royalty and then by the burghers for the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting rose as fashionable for the affluent and royalty, but after that time the trend did not last.

The first yacht group in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had much naval panoply and rigour. The closest thing to racing was the “chase,” in which the “fleet” pursued an imagined enemy. The club endured, largely as a social club, until 1765, and in 1828, when joining with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated manner 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 known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been initiated 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 perpetual location of British yachting. The organisation at Cowes became the Royal Yachting Club, again at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the society life was wonderful. Ultimately Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English took power. Sailing was for the most part for leisure and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in the area from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of bigger yachts was first heavily put upon by the success of America, which was designed by George Steers for a club led 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. Earlier yachts were not designed and built in today’s sense, with just a model for an outline. Not until the later half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the application of the research of aerodynamics do for the craft of sails and rigging what such study had already done for hulls.

Because most of all sailboats had to be individually built, there came a desire for handicapping boats previous to the one-design class boats were designed. Hence, a rating rule was decreed, which is found in the International Rule, adopted in 1906 and revised in 1919. In the present day, one of the fastest flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to the same specifications in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing between these boats can be held on an even playing field with no handicapping necessary. A perfect example is the standard International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

For the time that yachting belonged largely for the royal and the affluent, money was no issue, and the size of boats developed, in both length and weight. The promotion and desire of smaller yachts came in the latter half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage 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 less sizeable craft. Later in the 20th century, particularly after World War II, smaller racing and recreational craft became more common, 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
Following the decade 1840–50, during which steam was set to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were employed more and more in personal craft. Bigger power yachts were developed to a high degree, and long-distance cruising became a favoured pastime of the wealthy. The early power yachts were paddle-wheel boats; these then made way to those powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries with both sail and power were the yacht standard for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the large part were only power yachts that had gasoline or diesel engines.

In the last decade of the 19th century there was a push in the design of bigger steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated 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 gave active service for World War II.

As more sizeable and more reliable internal-combustion engines were produced, many big boats started using them for power. The development of the diesel engine, with heavy oil for fuel, progressed for World War I. During the decade that followed, big power-yacht creation grew, hitting a climax in the Orion (1930) at 3,097 tons. During that point the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power yachts declined in 1932, and the style after that was in preference of smaller, less pricey craft. Following World War II, many small naval boats were sold to private owners for conversion to yachts. In the late 20th century, yachting is a internationally loved activity enjoyed by thousands of yachtsmen individually owning and keeping their own small pleasure boats. The amount of yachts and owners increased steadily, not only in the traditional locations on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the impact they have on the placement of income and wealth. A proportional tax is a kind that imposes the same relative liability on all the taxpayers—i.e., when tax liability and income grow in the same proportion. A progressive tax is recognised by a more than proportional growth in the tax burden relative to the growth in income, and a regressive tax is recognisable by a less than proportional increase in the comparative burden. Ergo, progressive taxes are seen as taking away the lack of equality in income distribution, but regressive taxes are believed to have the result of an increase in these inequalities.

The taxes that are generally thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so within the upper-income demographic—particularly if a taxpayer is able to reduce his tax base by claiming deductions or by excluding some certain income elements from his taxable income. Proportional tax rates when applied to lower-income demographics would also be more progressive if such personal exemptions are declared.

Income measured over the period of a year may not definitely offer the most accurate measure of taxpaying requirements. For example, transitory growth in income could be saved, and during temporary declines in income a taxpayer may choose to provide for consumption by decreasing savings. Therefore, if taxation is made comparable along with “permanent income,” it would be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (with the exception of those on luxuries) are usually regressive, because the share of individual income consumed or spent on a specific good declines as the level of personal income grows. Poll taxes (also termed head taxes), levied as a flat amount per capita, clearly are regressive.

It is not simple to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant for the most part on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effect of taxation, it is relevant to differentiate between varied concepts of tax rates. The statutory rates are specified in law; commonly these are marginal rates, but in some cases they are median rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income increases by one dollar. Therefore, if tax liability rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that increase as income grows. Heavy analysis of marginal tax rates should regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than specified in the statutory rates. Since marginal rates display how after-tax income increases or decreases in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applied 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 display the part of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually grow with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households could dwarf these effects, producing regressivity, as signified by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs used for projection systems are generally small reflective or transmissive panels illuminated by a powerful arc lamp source. A line of lenses expands the reflected or transmitted image and sends it onto the screen. In front-projection systems the LCD is set on the same area of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of higher expense and capability can utilise three distinct LCD panels, reflecting separate red, green, and blue images that come together to reflect a coloured picture on the screen.

The growing demand for video presentations has had a particular emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices utilizing smectic liquid crystals, certain kinds of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. With it the liquid crystal molecules are set out in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are on a tilt, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the shape 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 through the plane of the layers. So, there exists 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 or when one or more polarizers are utilised.

SSFLC devices have been commercialized for large passive-matrix presentations, but their cost and complex detail has impeded them from having any remarkable effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as elements in projection systems or as viewfinders in digital cameras. Their fast reacting allows them to be made use of in time-sequential colour systems, in which highly expensive colour filters are removed for a coloured backlight that flashes red, green, and blue in quick pulsing (approx 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state during the red and green periods and then to a nontransmissive state in the blue period, with the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture objects, the chair may be the most imperative. While the majority of other objects (except the bed) are meant to support objects, the chair supports your human form. The term chair is meant to be said here in the larger sense, from stool to throne to derivative items including a bench or sofa, which should be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as curious as its history as a creative craft. The chair is not just a physical support or an aesthetic piece of art; it can also be an indicator of social standing. From the old royal courts there were social differences between sitting on a chair with arms, or a chair with a back but no arms, or worse having to squat on a stool. In the last century, a director’s and/or manager’s chair has risen iconic of superior position, as well as in democratic parliaments the speaker sits on an elevated level.

In a furniture creation, the chair encompasses a variety of different forms. There are chairs structured to fit man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). Since historical days there were chairs used for birth (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). We design 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.

Modern day living has designated special chairs for use in automobiles and aircraft. Every one of these chair forms has evolved to suit to growing human requirements. Due to its particular connection with man, the chair lives to its full importance only when being utilised. Though it does not make a difference to one’s appreciation of a cupboard or a bureau whether there might be things inside or not, a chair is understood and judged by a person utilising it, for chair and sitter suit one another. Thus the different parts of a chair are labeled likened to the areas of our human body: arms, legs, feet, back, and seat.

Because the primary work of your chair is to support a human body, its credit is tested basically for how well it measures up to this practical purpose. Within the design of the chair, the maker is limited in some static regulation and principal measurements. Through these rules, however, the chair builder has great freedom.

The history of the chair was an epoch of several thousand years. There are societies that had made iconic chair types, expressive of the foremost task in the spheres of craft and creativity. Within these such cultures, particular 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 careful make, are today known from tomb discoveries. One of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair has four legs crafted similar to those of some animal, a curved seat, and a sloping back supported from vertical stretchers. In this way a stable triangular structure was made. There was from our knowledge no significant variation between the creation of Egyptian thrones and chairs for typical citizens. The real variation lies in the complex ornamentation, in the selection of more costly inlays. The Egyptian folding stool in all likelihood was made for an easily carried seat for army officers. As a camp stool this type continued til much later periods of time. But the stool also was made for the character of a ceremonial seat, its mechanical task as a folding stool being forgotten. This can now be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are made in the construction of folding stools but can’t be folded as the seats were formed with wood. The easy structure of the folding stool, consisting of two frames that cycle on metal bolts and bear a seat of leather or fabric secured between them, then came up somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this kind is the folding stool, of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not from any ancient specimen still existing but as found in a trove of pictorial evidence. The most recognisable is the klismos placed on the Hegeso Stele at the Dipylon burial location near Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of them were shown. These strange legs were likely to have been executed from bent wood and were probably put under extreme pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat would have had to be therefore extremely stable and were visibly drawn.

The Romans adopted the Greek style; a number of models of seated Romans offer examples of a denser and in appearance kind of more crudely designed klismos. Both styles, the light and heavy, were brought back as part of the Classicist era. The klismos style can be evidenced in French Empire chairs, in English Regency, and in special brands of considerable originality of Denmark and Sweden from 1800.

China
The past of the chair in China is not able to be tracked as far back as the progression of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an undamaged collection of images and works of art has been kept, displaying the inside and exteriors of Chinese houses and their furniture. Preserved also since the 16th century are a trove of chairs made from wood or lacquered wood, that bear an interesting similarity to images of past chairs.

Like in Egypt, there existed two iconic chair forms in China: a chair that had four legs and a folding stool. That four-legged chair is designed both with and without arms but always having its square seat and straight stiles (standing side supports) to give support to the back. In one form, it has been seen, the stiles could be delicately curved above the arms in order to fit the form of the S-shaped back splat (the central upright of the chairback). Together, the three parts are mortised onto the yoke-like top rail. While the style of the Chinese back splat exercised an introduction for English chairs in the Queen Anne period, wooden members that merely to a particular extent embolden corner joints (and furthermore were loose into the bargain) are an element particular to Chinese chairs. The four legs are set through the seat frame, which ends over the rounded staves. All members are round in section or is given rounded edges—referable maybe to the bamboo tradition. The seat is not pleasant and occasionally had a plaited seat. These chairs required of the sitter to remain stiff and upright; when too much weight is exerted on the back, the chair has a tendency to topple over. In patriarchal Chinese homes of this period armchairs probably were only for the senior people, for they were held in great esteem.

The Chinese folding stool is understood to have come to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is elegantly fixed to the two legs of the stool with a curved member, which is usually provided with metal mounts. From a Western perspective the resulting effect of these two furniture forms is stylized. The structure and decorative elements are combined in a manner that is both naïve and refined. The patchwork appearance is an outcome of the way that the individual items do not look to have been put together with either glue or screws, but have been mortised on one another and fixed in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its mark on the chair. Artworks display a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to produce a pattern of small pads. The front board and a similar board from the back could be folded after loosening some little iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, during the same era, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is displayed in engravings of the inside of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair may also be made in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not held that the form actually started in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was crafted in considerable amounts, as can be surmised 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 delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is, as developed in Paris around 1750—disseminated through most of Europe and was imitated or copied during the mid-20th century. The chair owes its popularity to a combination of relaxation and charm. The seat adheres to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are tiny upholstered pads on the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those employ wood of quite thick density; but every member is deeply molded, all extra wood has been removed, and more expensive designs may be further embellished with intricately delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used as an alternative to upholstery.

English chairs of the 18th century were more differentiated in form than the French. The French touch for stylistic uniformity, which lead from the royal circles in Paris and Versailles within 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 popular 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, indicate 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 provides the figures from which accounts are written but is a separate process, prior to accounting.

Basically, bookkeeping provides two kinds of information: (1) the current value, or equity, of an entity and (2) changes in value—profit or loss—taking position in the business over a particular time.

Management officials, investors, and credit grantors all require such information: management to assess the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the outcomes of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors so as to judge the financial statements of a business in judging whether to allow a loan.

Traces of financial and numerical recordkeeping can be seen for nearly every state with a commercial history. Records of business contracts have been discovered in the remains of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The two-entry manner of bookkeeping came up with the progression of the commercial republics of Italy, and instruction manuals for bookkeeping were produced within the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial bookkeeping a paramount factor. The past of bookkeeping, in fact, reflects the history of commerce, industry, and government and, in part, helped shaping it. The international revolution of industrial and commercial activity demanded higher sophisticate decision-making methods, which in turn called for greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislature became more detailed and resulted in greater need for information; entities had to have information available to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the need for bookkeeping for their inner operations became higher.

While bookkeeping methodology can be extremely detailed, it is all based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and such), and the ledger has the record of individual accounts. The daily records in the journals are put in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The duty of the income statement or profit-and-loss statement is to show an analysis of those changes that occurred in the business equity from the transactions of the period. The balance sheet gives the financial position of the corporation at a particular day derived 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 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 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.
