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

The common question customers ask when looking for a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and different types available, it can be challenging for customers to choose between these technologies. The fact is that LCD projectors give far superior image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with reproducing a similar rate of image quality.

It’s like a set of blinds in your household for your bedroom window. By pulling on a rod you can turn the shutters open or closed, according to whether you want to let light in or not. And such is exactly how an LCD projector behaves. Each pixel operates like an individual shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the image reaches your screen is absolutely significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels form the elements of the image by shining each pixel on and off. The pixels are then meshed in a glass prism to create the projector image. A point to realise about LCD projectors is that all three colours are delivered onto your screen at once. The way a DLP projector functions is totally different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is sent through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of projecting an image casts 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 sent in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into a total image. In LCD projectors, all colours are available all the time to deliver high brightness and fantastic colour accuracy. In DLP, only one colour is available at once, resulting in lower colour brightness and accuracy. Some DLP manufacturers have added a white segment for the colour wheel to improve brightness generally, but this goes and lessens colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and therefore must be superior. For those who do not know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is able to produce. DLP projectors do have high contrast specifications as compared to the majority of LCD projectors. At a glance, this appears to be a benefit, however, in reality, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you plan to view requires moving images, DLP projection technology also has image marks, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because all the colours are projected with the others. DLP designers have developed 3DLP solutions using 3 chips to answer the colour break up error, but the cost of these projectors make them not practical for many businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Remember back to high school science, and recall when they taught you how various colours of light refract various amounts when shone through the same lens. The problem with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Often with a DLP projector, an extra yellow colour will show above and a superfluous blue will come through below an image of something as simple as a straight black line. In building LCD projectors can be adjusted to take away these effects on the projected image, because each colour is projected on its own LCD panels.

The isolated real benefit (excluding price) with choosing a DLP projector is its smaller overall size and weight. However, this is only relevant for mobility and must be traded off against the image superiority of LCD projectors. If the result of the picture quality is important to you, then the choice is no-brainer. Choose an LCD projector! LCD projectors will always make bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the early yacht was a leisure craft used initially by royalty and later by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy 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, reigned 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting became classy for the rich and royalty, but after that time the fashion did not last.

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

Yacht racing was seen in some ordered fashion on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been formed at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British racing. The society at Cowes became the Royal Yachting Club, again at the ascension of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for great bids were held, and the club life was splendid. Eventually Royal Yachting Club boats increased in size to bigger 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 held power. Sailing was for the most part for fun and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a standard of luxury and sophistication for the later yachts in the area from the late 19th century. The first persisting American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The style of bigger yachts was originally greatly put upon by the win of America, which was created by George Steers for a syndicate started 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. Earlier yachts were not designed and built in a contemporary sense, with merely a model used. Not until the latter half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the application of the science of aerodynamics do for the structure of sails and rigging what such study had done earlier for hulls.

Because almost all sailboats were individually built, there was a need for handicapping boats previous to the one-design class boats were designed. Thus, a rating rule was written, which resulted in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are built to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing those boats can be held on an even basis with no handicapping required. A great example is the uniform International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

So long as yachting was done largely for the royal and the wealthy, money was no problem, and the size of boats grew, in both length and weight. The rise and desire of smaller craft occurred in the later half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of small yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and pleasure boats became commonplace, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, in which steam began to take the place of sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly used in leisure yachts. Large power yachts were progressed to a high element, and long-distance travel turned into a preferred occupation of the affluent. The first power yachts were paddle-wheel boats; these then gave rise to yachts powered by the completely submerged screw or propeller sort of propulsion. As in the case of naval and merchant craft, auxiliaries possessing both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, several yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of bigger steam yachts. Conspicuous among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 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 during World War II.

As bigger and more dependable internal-combustion engines were produced, many large boats were using them for power. The development of the diesel engine, using heavy oil for fuel, was furthered during World War I. From the decade following that, big power-yacht creation blossomed, climaxing 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 building of large power craft declined in 1932, and the fashion after that was toward smaller, less expensive craft. Following World War II, a lot of small naval boats were sold to private owners for conversion to yachts. At the late 20th century, yachting has become a widespread loved sport enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small pleasure yachts. The number of yachts and owners increased steadily, not only in the traditional areas along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the placement of income and wealth. A proportional tax is the kind of tax that puts the same relative burden on all taxpayers—i.e., when tax liability and income increase in relative levels. A progressive tax is recognised by a larger than proportional growth in the tax liability relative to the growth in income, and a regressive tax is recognisable by a less than proportional increase in the related onus. Hence, progressive taxes are viewed as removing the lack of equality in income distribution, while regressive taxes are found to result in increasing these inequalities.

The taxes that are generally considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so for the upper-income categories—especially if a taxpayer is permitted to lessen his tax base by claiming deductions or by leaving out some particular income parts from his taxable income. Proportional tax rates that are applied to lower-income categories can also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the period of a year does not necessarily offer the most appropriate measure of taxpaying requirement. For example, transitory rises in income could be saved, and within temporary declines in income a taxpayer might choose to provide for consumption by decreasing savings. Ergo, if taxation is made comparable alongside “permanent income,” it should be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (except those on luxuries) are usually regressive, because the dissemination of own income consumed or spent on specific goods decreases as the rate of personal income rises. Poll taxes (also known as head taxes), calculated as a flat amount per capita, patently are regressive.

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

In considering the economic effect of taxation, it is necessary to differentiate between differing concepts of tax rates. The statutory rates include those specified in legislature; usually these are marginal rates, but for some cases they are average rates. Marginal income tax rates signify the fraction of incremental income that is taken by taxation when income is increased by one dollar. So, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations often contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates are required to review 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 rise in income, the marginal rate is 20 percentage points higher than indicated by the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the important ones for regarding incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate to apply to income from business and capital, as it may be dependant on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates display the percentage of total income that is required in taxation. The pattern of average rates is the one that is important for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are provided for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the flip side, preferential treatment of income received mostly by high-income households could dampen these effects, producing regressivity, as displayed by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs built for projection systems are most often small reflective or transmissive panels lit up by a bright arc lamp source. A line of lenses magnifies the reflected or transmitted image and then casts it on the screen. For front-projection systems the LCD is located on the same side of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of higher expense and capability may be found with three distinct LCD panels, forming separate red, green, and blue images that mesh to make a coloured picture on the screen.

The growth in requirement for pictographic displays has put a special emphasis on the switching speed of liquid crystals. This has required the invention of devices employing smectic liquid crystals, some types of which have a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. Within it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are on a slant, as shown in the figure. The host liquid crystal contains optically active molecules, and a minor outcome 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 within the plane of the layers. Hence, there is 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 corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been produced for big passive-matrix displays, but their expensiveness and detail has impeded them from having any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate reaction allows them to be made use of in time-sequential colour systems, in which dear colour filters are replaced with a coloured backlight that flashes red, green, and blue in fast pulsing (about 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods and to a nontransmissive state during the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture items, the chair might be the most imperative. While most other pieces (save for the bed) are intended to support objects, the chair supports the human form. The term chair must be said here in the widest sense, from stool to throne to complex items like the bench and sofa, which might be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinguished.

The social history of the chair is as exciting as its history as a creative art. The chair is not only a physical support and/or aesthetic craft; it is also an indicator of social status. At the old royal courts there were social differences between possessing a chair with arms, sitting on a chair with a back but without arms, and having to cope with a stool. Since the 20th century, a director’s and/or manager’s chair has risen an indicator of superior position, like in democratic governments the speaker sits on an elevated level.

As a furniture construction, the chair ranges from a variety of different models. There are chairs structured to fit man’s age and physical form (the high chair, the wheelchair) and to indicate his status in society (the executive chair, the throne). From historical days there were chairs used for birth (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). We design chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has demanded unique chairs in automobiles and aircraft. All of these chair types have evolved to match to different human needs. From its particular link with man, the chair exists to its full advantage only when in employ. Whereas it does not make a difference to one’s appreciation of a cupboard or a dresser drawers whether there are items inside or not, a chair is best seen and fairly tested with a person sitting in it, because chair and sitter suit one another. Thus the different elements of a chair are named like the areas of the human shape: arms, legs, feet, back, and seat.

Because the original job of a chair is to support a human body, its credit is evaluated principally on how well it measures up to this practical purpose. Within the structure of the chair, the carpenter is bound by the static regulations and principal measurements. Through these limitations, however, the chair builder has large freedom.

The history of the chair lasted over dates of several thousand years. There existed cultures that made distinctive chair forms, as expressions of the foremost work in the spheres of technique and art. From these such civilisations, special 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 items of skilled design, are now seen from tombs. One of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs designed similar to those of a designated animal, a curved seat, leading to a sloping back supported from vertical stretchers. In this design a stable triangular structure was created. There appeared to be no notable change from the design of Egyptian thrones and chairs for ordinary people. The main change exists in the complexity of ornamentation, in the selection of more costly inlays. The Egyptian folding stool most probably was created as an easily portable seat for army officers. As a camp stool the kind stayed around until much later points in time. But the stool also then was designed for the role of a ceremonial seat, its mechanical role as a folding stool fast forgotten. This can today be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the construction of folding stools but are not able to be folded because the seats are worked of wood. The simple manufacture of the folding stool, consisting of two frames that rotate on metal bolts and have a seat of leather or fabric secured between them, is seen somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of these is the folding stool, from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not in any ancient specimen still in form but as in a variety of pictorial evidence. The better known is the klismos drawn on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were displayed. These unusual legs were understood to be manufactured of bent wood and were thus had to bear huge pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat are therefore very solid and were overtly pointed out.

The Romans embued the Greek style; a number of statues of seated Romans offer chairs of a thicker and are a somewhat less intricately designed klismos. Both features, light or heavy, were revived within the Classicist era. The klismos style can be found in French Empire styles, in English Regency, and in some special brands of notable iconicism within Denmark and Sweden during 1800.

China
The past of the chair in China is not able to be tracked as far as the progression of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unbroken folio of drawings and artworks has been preserved, displaying the inside and outside of Chinese homes and the kinds of furniture. Kept also from the 16th century are a trove of chairs made of wood or lacquered wood, that bear an interesting likeness to representations of older chairs.

Just as in Egypt, there existed two standard chair designs in China: a chair that had four legs and a folding stool. This chair can be seen both with or without arms but always with its square seat and straight stiles (vertical side supports) to firm the back. In one design, though, the stiles are slightly curved over the arms in order to suit the structure of the S-shaped back splat (the basic upright of a chairback). The three limbs are mortised in the yoke-like top rail. Although the style of this back splat had an introduction for English chairs in the Queen Anne period, wooden members that could merely to a limited limit embolden corner joints (and then were loose as a result) are a signature exclusive to Chinese chairs. The four legs pass through the seat frame, which ends upon the rounded staves. All the members are round in section or has rounded edges—referable as may be to the bamboo tradition. The seat is not comfortable and may have had a plaited texture. These chairs required the sitter to stay stiff and upright; when too much weight is forced on the back, the chair has a habit of toppling over. In patriarchal Chinese homes of this period armchairs likely were kept for senior persons in the family, for they were respected greatly.

The Chinese folding stool is understood to have come to China from the West. It is not dissimilar very much from the Egyptian and Scandinavian folding stools, but it has a variation in that the top rail is delicately held to the two legs of the stool by use of a curved member, which is usually designed with metal mounts. From a Western point of view the ultimate effect of both of these furniture items is stylized. The constructive and decoration issues are combined in a manner that is simultaneously naïve and refined. The patched up appearance is an upshot of the way that the individual parts do not seem to have been fixed by use of either glue or screws, but have been mortised on one another and fixed in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Paintings display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between the layers, stitched to bring up a pattern of small pads. The front board and a similar board from the back could be folded after unscrewing some tiny iron hooks. Therefore the chair was a readily portable piece of furniture while traveling which, in the same era, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is evidenced in engravings of interiors of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair is also made in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not decided that the form actually started in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slim shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was crafted in large amounts, as can be seen from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up along a wall. The style asserts itself by virtue of its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, to say, as brought out in Paris around 1750—spread through most of Europe and was imitated or copied in the mid-20th century. The model owes the popularity to a combination of relaxation and delicacy. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of fairly thick measurements; but all the members are deeply molded, all extra wood has been sanded away, and more expensive designs can be further embellished with highly delicate and decorative carving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all upholstery on the seat, back, and armrests; crosshatched cane is in some cases used in place of upholstery.

English chairs of the 18th century were more open in form than the French. The French touch for stylistic uniformity, which disseminated from the aristocratic circles in Paris and Versailles over most of France and was popular 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 popularised 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 brands 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, suggest that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the function of a business. Bookkeeping creates the figures from which accounts are made but is a distinct process, prior to accounting.

Predominantly, bookkeeping grants two types of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking position in the business over a given period.

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

Pieces of financial and numerical records have been found for just about every nation with a commercial history. Records of trading contracts were uncovered in the remains of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The two-entry way of bookkeeping came with the progression of the business republics of Italy, and manuals for bookkeeping were created during the 15th century in many Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial bookkeeping a must-have. The past of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, partially, assisted forming it. The global spread of industrial and commercial activity needed greater professional decision-making methods, which itself needed more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government legislation became more important and resulted in greater requirement 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 developed in size, and the requirement for bookkeeping for their own operations increased.

While bookkeeping processes can be extremely multifaceted, all are based on two styles of books employed in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger should have the records of individual accounts. The daily records kept in the journals are written in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The duty of the income statement or profit-and-loss statement is to display an analysis of those changes that happen in the enterprise equity from the operations of the period. The balance sheet shows the financial situation of the entity at any particular day in terms of 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.
