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

The typical question asked when acquiring a new projector for the home, office, or classroom is: would 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 top projector imaging technologies. With so many brands and types available, it can be confusing for consumers to choose between the two technologies. Ultimately LCD projectors provide far superior image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with reproducing a similar rate of image quality.

Imagine a set of blinds in your house over your bedroom window. By a twist of a rod you can make the shutters open or closed, according to whether you want to let light in or not. This is exactly how an LCD projector functions. Each pixel works like a unique shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as experts 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 is turned on to when the image reaches your screen is ultimately important in regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which send the coloured light to 3 separate LCD panels. The 3 LCD panels make the elements of the image by shining each pixel on and off. The pixels are then meshed in a glass prism to deliver the projector image. An important point to know about LCD projectors is that all three colours are directed onto your wall all at once. The way a DLP projector works is vastly different and even the way an image comes out is not the same. With DLP, white light from the lamp is directed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to construct 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 combine each coloured element of the image into a complete image. Using LCD projectors, all colours are available all the time to create top brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP designers have placed a white segment for the colour wheel to improve brightness overall, but this goes and degrades colour accuracy.

I see in forums all the time that DLP offers a higher contrast ratio and as such 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 system is capable of producing. DLP projectors do provide high contrast specifications when compared to most LCD projectors. Initially, this appears to be a plus, however, in reality, the true black level is determined by the ambient light in the room in which the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to see includes moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change between the time red, blue and green colours are projected. LCD projectors do not have this problem because every colour is sent simultaneously. DLP developers have created 3DLP solutions using 3 chips to fix the colour break up problem, but the price tag of these projectors make them impractical for the large part of businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and remember when they taught you how different colours of light refract varied amounts when directed through the same lens. The downside with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are different and refract light at different levels. Often with a DLP projector, some yellow colour will be projected above and some blue will come up below something as simple as a single black line. During manufacturing LCD projectors can be fixed to reduce these effects on the projected image, as each colour is projected on its own LCD panels.

The one veritable benefit (excluding price) with buying a DLP projector is its smaller total size and weight. However, this is only relevant to mobility and needs to be traded off against the image superiority of LCD projectors. If overall picture quality is vital to you, then the solution is simple. Take an LCD projector! LCD projectors will always make bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the initial yacht became a leisure craft used mostly by royalty and then by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting became popular among the wealthy and royalty, but after that period the habit did not last.

The first yacht association 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 formality. The closest thing to racing was the “chase,” for which the “fleet” pursued an imagined enemy. The club went on, for the large part as a social club, until 1765, and in 1828, when joining with other organisations, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated method on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with 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 continuing setting of British yachting. The organisation at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for high stakes were held, and the social life was wonderful. It came to be that the Royal Yachting Club boats were raised in size to more than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English took 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 standard of luxury and sophistication for the later yachts in the area from the late 19th century. The first persisting American yacht organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The design of bigger yachts was originally largely impacted by the success of America, which was created by George Steers for a association 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. Early yachts were not designed and built in today’s sense, with only a model for an outline. Not until the later half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the design of sails and rigging what science had previously done for hulls.

Because almost all sailboats had been individually built, there came a requirement for handicapping boats previous to the one-design class boats were designed. Therefore, a rating rule came into being, which ended up in the International Rule, adopted in 1906 and edited in 1919. Today, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are manufactured to standard dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between such boats can be done on an even basis with no handicapping necessary. A great example is the standard International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

For the time that yachting belonged largely for the aristocracy and the rich, expense was no problem, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller boats came 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 voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the hardiness of small yachts. Later in the 20th century, notably after World War II, smaller racing and pleasure craft became commonplace, down to the dinghy, a favoured 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
After the decade 1840–50, in which steam started to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in personal craft. Bigger power yachts were furthered to a high degree, and long-distance sailing was a fond activity of the wealthy. The earliest power yachts were paddle-wheel boats; those then gave way to yachts powered by the completely submerged screw or propeller kind of propulsion. Like naval and merchant vessels, auxiliaries possessing both sail and power were the yacht archetype for several years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the large part were only power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push 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 operated by a crew of more than 150. The Mayflower, purchased 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 more sizeable and better quality internal-combustion engines were developed, many large yachts began using them for power. The creation of the diesel engine, employing heavy oil for fuel, was furthered during World War I. From the decade after, bigger power-yacht creation grew, 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 building of large power craft lessened from 1932, and the style from then was for smaller, less expensive craft. Following World War II, many small naval boats were bought by private owners for conversion to yachts. By the late 20th century, yachting has become a internationally beloved activity enjoyed by thousands of yachtsmen individually sailing and keeping their own small pleasure yachts. The amount of craft and sailors has increased steadily, not only in the traditional places along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the impact they have on the distribution of income and wealth. A proportional tax is a kind that applies the same relative requirement on every taxpayer—i.e., where tax liability and income increase in relative proportion. A progressive tax is recognisable by a greater than proportional increase in the tax onus in relation to the growth in income, and a regressive tax is recognised by a less than proportional rise in the comparative burden. So, progressive taxes are regarded as removing inequity in income distribution, while regressive taxes may have the effect of an increase in these inequalities.

The taxes that are often considered progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so in the upper-income demographic—especially if a taxpayer is permitted to lower his tax base by nominating deductions or by taking particular income parts from his taxable income. Proportional tax rates that are applied to lower-income groups will also be more progressive if such personal exemptions are made.

Income measured over the period of a year does not necessarily provide the most suitable measure of taxpaying requirements. For example, transitory growth in income can be saved, and in temporary declines in income a taxpayer could elect to finance consumption by decreasing savings. So, if taxation is made comparable with “permanent income,” it can be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (excepting those on luxuries) are mostly regressive, because the portion of own income consumed or spent for a specific good lessens as the level of personal income rises. Poll taxes (also called head taxes), calculated as a fixed amount per capita, clearly are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic purpose of taxation, it is important to differentiate between varied ideas of tax rates. The statutory rates will be specified in the legislation; usually these are marginal rates, but in some cases they are median rates. Marginal income tax rates signify the fraction of incremental income demanded by taxation when income grows by one dollar. Ergo, if tax liability increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislation usually contain graduated marginal rates—i.e., rates that rise as income rises. Heavy analysis of marginal tax rates must regard provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than nominated by the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more complicated to understand the marginal effective tax rate applied to income from business and capital, since it may be reliant on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates show the percentage of total income that is required in taxation. The pattern of average rates is the one that is in consideration for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally grow with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received for the most part by high-income households might swamp these effects, producing regressivity, as signified by average tax rates that decrease as income increases.

Tangalooma Island Resort Holiday: One of the Best Holiday Destination in Australia

Tangalooma Island Resort is an earthly paradise that can be found in Tangalooma, Queensland in Australia. It was formerly a whaling station and was changed into an island holiday destination because of its distinctive flora and fauna and its breathtaking views. Couples or families looking for a super vacation destination can expect to certainly treasure a Tangalooma Island Resort holiday.

This earthly paradise lies on the west side of Moreton Island, close to Moreton Bay. It is famous for its rare white beaches and has been a whale sanctuary since the year the whaling station was closed down, in 1962.

When having a Tangalooma Island Resort vacation, you can expect to be assisted by friendly and understanding staff while at the same time being taken aback by the beautiful white sand beaches. You could also enjoy a wide range of activities from wreck diving to feeding and playing with the dolphins. You will totally treasure every second of your holiday.

Tangalooma has a very tiny population of 300, but tourists has ensured this small township to grow and maintain the panoramic and majestic glory of the island. Over 3500 travelers visit the resort weekly, and even more during peak seasons. The local government has also created a Centre for Marine Education and Conservation, to instruct and train the local population along with tourists about the requirement of upkeeping the marine life in the area. The centre employs marine biologists to lead information awareness drives and programs, which is part of the nature tour package for holidaymakers.

Throughout a Tangalooma Island Resort getaway, everyone cannot help but treasure their stay as they have more than eighty activities to pick from – but perhaps the highlight of your holiday will be the opportunity to experience the beauty of nature. Tourists can go sight-seeing and see the glorious sunrise and sunset at the beach, or play with the dolphins that live around the resort.

The Development of Data Projectors

The LCDs used for projection systems are most often small reflective or transmissive panels illuminated by a strong arc lamp source. A series of lenses enlarges the reflected or transmitted image and sends it on the screen. With front-projection systems the LCD is situated on the side of the screen as the viewer, but in rear-projection systems the screen is illuminated from behind. Projectors of greater expense and capacity might use three separated LCD panels, reflecting separate red, green, and blue images that combine to reflect a coloured picture on the screen.

The growing demand for video presentations has had a growth in emphasis on the switching speed of liquid crystals. This has led to the creation of devices employing smectic liquid crystals, some of which have a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. In 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 on a slant, as shown in the figure. The host liquid crystal contains optically active molecules, and a subtle result of the optical activity and the angle 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. Thus, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark when one or more polarizers are employed.

SSFLC devices have been produced for large passive-matrix displays, but their high cost and detail has prevented them from creating any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their immediate responding allows them to be used 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 fast speed (approximately 100 cycles in a second). For example, the liquid crystal can be switched to a transmissive state in 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

Out of all furniture forms, the chair might be the most imperative. While the majority of other items (apart from the bed) are meant to support objects, the chair supports a human form. The term chair can be viewed here in the most general sense, from stool to throne to further items including the bench and sofa, which should be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently defined.

The social history of the chair is as interesting as its history as art and craft. The chair is not just a physical support and aesthetic artwork; it is also symbolic of social rank. Within the Medieval royal courts there were clear differences between possessing a chair with arms, sitting on a chair with a back but without arms, or having to utilise a stool. From the last century, a director’s and manager’s chair has become iconic of superior status, as well as in democratic government meeting the speaker sits on an elevated level.

As a furniture form, the chair encompasses a variety of different makes. There are chairs manufactured to match man’s age and physical condition (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). From historical days there were chairs to be born in (birth chairs); since 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 can have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated new chairs in automobiles and aircraft. Each of these chair forms has changed to match to changing human desires. From its unique link with man, the chair exists to its full purpose only when in use. Though it does not make any difference to one’s appreciation of a cupboard or a chest of drawers if there might be items inside or not, a chair is understood and judged best by a person sitting on it, because chair and sitter complement each other. Thus the various parts of the chair have been given names corresponding to the parts of a human parts: arms, legs, feet, back, and seat.

Because the basic function of a chair is to support a body, its value is tested primarily from how suitably it does measure up to this practical job. Within the build of a chair, the chair maker is restricted in some static rules and principal measurements. Inside these limitations, however, the chair builder has extensive freedom.

The history of the chair covers an era of several thousand years. There were cultures that have created distinctive chair forms, seen of the highest craft in the areas of craft and art. Out of those peoples, a note must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of careful craft, are now seen from tomb findings. First of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs shaped as akin to those of some animal, a curved seat, and with a sloping back supported from vertical stretchers. In this design a stable triangular construction was made. There was apparently no particular difference between the structure of Egyptian thrones and chairs for typical citizens. The only change exists in the level of ornamentation, in the selection of pricier inlays. The Egyptian folding stool probably was crafted to be an easily stored seat for soldiers. As a camp stool this form existed until much later points in time. But the stool then also was designed as the purpose of a ceremonial seat, its mechanical task as a folding stool ignored or forgotten. This can from today’s evidence be noted, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the form of folding stools but aren’t able to be folded because the seats are worked out of wood. The simplistic construction of the folding stool, made of two frames that cycle on metal bolts and have a seat of leather or fabric secured between them, then came again but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of those is the folding stool, from ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not with any ancient object still around but as found in a trove of pictorial material. The significant kind is the klismos depicted on the Hegeso Stele at the Dipylon burial place just out of Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, only two of which would be visible. These strange legs were considered to be created out of bent wood and were as such put under great pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat would have been therefore very strong and were visibly signified.

The Romans borrowed from the Greek design; a number of models of seated Romans offer examples of a more heavyset and which appear to be a slightly less intricately designed klismos. Both kinds, light and heavy, were seen again during the Classicist era. The klismos style can be found in French Empire furniture, in English Regency, and in some special kinds of profound individuality within Denmark and Sweden around 1800.

China
The progression of the chair in China cannot be tracked as well as in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) a full folio of images and artworks was preserved, showing the interior and exterior of Chinese households and the furniture. Another preservation of the 16th century are some chairs of wood or lacquered wood, that hold an astonishing similarity to representations of previous chairs.

Just as in Egypt, there existed two major chair designs in China: a chair with four legs and a folding stool. This chair can be constructed both with or without arms though always with the square seat and straight stiles (standing side supports) to support the back. In one design, it must be said, the stiles are lightly curved above the arms in order to suit the form of the S-shaped back splat (the main upright of a back). Together, all three sections are mortised into the yoke-like top rail. Though the innovation of a back splat exercised an introduction for English chairs of the Queen Anne period, wooden items that only to a restricted ability reinforce corner joints (and are loose in the bargain) signify a signature signatory 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 have rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is uncomfortable and had on occasion a plaited bottom. These chairs needed the sitter to hold themselves stiff and upright; if too much pressure is placed on the back, the chair has a tendency to topple. In patriarchal Chinese houses of this period armchairs likely were allowed only for elderly family members, for they were respected greatly.

The Chinese folding stool is believed to have been brought to China from the West. It is not dissimilar that much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is prettily joined to the two legs of the stool by means of a curved member, which is more often than not possessing metal mounts. From a Western viewpoint the ultimate effect of both these furniture items is stylized. The constructive and aesthetic elements are combined in a style that is simultaneously naïve and refined. The piecemeal appearance is an outcome of the fact that the individual members do not look to have been fixed by either glue or screws, but have been mortised with one another and locked into its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Paintings project a design of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between, stitched to show up a pattern of little pads. The front board and a related board at the back could be folded after unscrewing some little iron hooks. Therefore the chair was a portable piece of furniture when traveling which, during the same time, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is evidenced in engravings of interiors of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair might also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the design actually began in The Netherlands. Typically, the legs of the chair are smooth, round in section, and of slender dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in impressive amounts, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of those chairs lined up along a wall. The form asserts itself by its shapely proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, as developed in Paris around 1750—disseminated over most of Europe and was imitated or copied into the mid-20th century. The chair owes such popularity to a combination of leisure and delicacy. The seat suits to the human body and permits a relaxed sitting 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 are achieved between seat frame, legs, and back conceal all the joints, which are strongly constructed on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of fairly thick density; but each member is deeply molded, all extraneous wood has been taken away, and finer items might be further embellished with special delicate and decorative carvings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for the upholstery on the seat, back, and armrests; cane is in some cases used as an alternative to upholstery.

English chairs from the 18th century were more open in form than the French. The French taste for stylistic uniformity, which lead from the royal circles in Paris and Versailles over most of France and found favour 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
In 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 styles 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 operation of a business. Bookkeeping provides the numbers from which accounts are drafted but is a distinct process, prior to accounting.

Predominantly, bookkeeping records two areas of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking place in the entity from a given period of time.

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

Traces of financial and numerical records can be seen for just about every state with a commercial history. Records of trade contracts have been uncovered in the remains of Babylon, and accounts for both farms and estates have been created in ancient Greece and Rome. The two-entry process of bookkeeping started with the development of the commercial republics of Italy, and instruction manuals for bookkeeping were created within the 15th century in several Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a must-have. The past of bookkeeping, in fact, closely resembles the past of commerce, industry, and government and, in some part, assisted to form it. The global revolution of industrial and commercial activity needed higher cosmopolitan decision-making procedures, which in its turn called for more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislation became more detailed and resulted in increased requirement for information; business firms had to show available information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the demand for bookkeeping for their own inner operations increased.

Though bookkeeping procedures can be rather multifaceted, all of it is based on two styles of books used in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, etcetera), and the ledger must have the records of individual accounts. The daily records kept in the journals are put in the ledgers.

At the end of each month, generally, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to show an analysis of those changes that have taken place in the ownership equity as a result of the events of the period. The balance sheet gives the financial position of the entity at any particular date with regard to 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 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.
