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

The most common question that is asked when looking for a new projector for the home, office, or classroom is: would I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and different types available, it can be confusing for consumers to make a choice between these technologies. The fact is that LCD projectors offer superior image quality and colour accuracy. The following article tells you why DLP projectors struggle with creating the same level of image quality.

Imagine a set of blinds in your home for your bedroom window. By a twist of a rod you can turn the shutters open or closed, depending on if you want to let light in or not. And such is exactly how an LCD projector works. Each pixel functions like its own shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point at which the projector is switched on to when the image reaches your screen is ultimately significant to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 stand alone LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then combined in a glass prism to deliver the projector image. Something important to know about LCD projectors is that all three colours are delivered onto your screen simultaneously. The way a DLP projector functions is vastly different and even the final product of how an image comes out is not the same. With DLP, white light from the lamp is directed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image requires a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into a whole image. In LCD projectors, all colours are available all the time to form top brightness and great colour accuracy. In DLP, only one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some DLP developers have placed a white segment in the colour wheel to improve brightness generally, but this goes and lessens colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and as such must be better quality. For those who are unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is capable of. DLP projectors do have high contrast specifications compared to many LCD projectors. At one glance, this appears to be an advantage, however, in truth, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you wish to view requires moving images, DLP projection technology also has image errors, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change position between the time red, blue and green colours are shone. LCD projectors do not have this downside because all the colours are projected with the others. DLP builders have created 3DLP solutions using 3 chips to fix the colour break up error, but the price of these projectors make them impractical for many businesses and consumers.

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

The only true advantage (excluding price) with taking a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to portability and must be traded off against the image advantages of LCD projectors. If the result of the picture quality is crucial to you, then the decision is easy. Go with an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the first yacht became a pleasure craft used initially by royalty and later by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting started 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 sent 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), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting was found to be classy among the rich and royalty, but after that point the trend 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 association, and had great naval panoply and gravity. The closest thing to racing boats was the “chase,” in which the “fleet” pursued a fictional enemy. The club endured, for the large part as a social club, until 1765, and in 1828, when merging with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated manner on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it was named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht club 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 continued setting of British yachting. The association at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing races for great bids were held, and the society life was superlative. It came to be that the Royal Yachting Club boats grew 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 persisted when the English had control. Sailing was mostly for leisure and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a minimum of luxury and elegance for the later yachts in that 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 on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within 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 sizeable yachts was first greatly affected by the win of America, which was designed by George Steers for a group led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with merely a model used. Not until the second half of the 19th century did what was known as 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 earlier done for hulls.

Because most of all sailboats had been individually manufactured, there was a need for handicapping boats as this was previous to the one-design class boats were built. Hence, a rating rule was decreed, which ended up in the International Rule, taken on in 1906 and amended in 1919. Today, one of the most rapidly flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to the same requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between those boats can be done on an even basis with no handicapping required. A great example is the generic International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

For the time that yachting belonged primarily for the aristocracy and the rich, expense was no object, and the size of boats developed, in both length and weight. The promotion and desire of smaller yachts happened in the latter half of the 19th century out of 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 value of less sizeable craft. Later in the 20th century, notably after World War II, smaller racing and recreational 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
Following the decade 1840–50, during which steam began to emulate sail power in public vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure boats. Sizeable power yachts were progressed to a high degree, and long-distance cruising turned into a fond occupation of the affluent. The first power yachts were paddle-wheel boats; they then made way to those powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant craft, auxiliaries with both sail and power were the yacht archetype for several years. By the later half of the 20th century, many yachts were still auxiliaries, but the large part were exclusively power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of more sizeable steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of 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 was used in active service in World War II.

As larger and better quality internal-combustion engines were developed, many large boats were using them for power. The establishment of the diesel engine, with heavy oil for fuel, advanced from World War I. In the decade after, bigger power-yacht building flourished, reaching a climax in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of bigger power yachts fell away from 1932, and the style thereafter was toward smaller, less expensive yachts. From World War II, lots of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a widespread popular activity enjoyed by thousands of yachtsmen individually sailing and upkeeping their own small recreational boats. The number of craft and owners increased steadily, not only in the traditional locations by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that imposes the same relative burden on all taxpayers—i.e., in the case where tax liability and income grow in equal scale. A progressive tax is recognisable by a more than proportional increase in the tax liability in relation to the growth in income, and a regressive tax is characterizable by a less than proportional growth in the relative liability. So, progressive taxes are seen as reducing inequalities in income distribution, while regressive taxes may have the effect of increasing these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so in the upper-income categories—in particular if a taxpayer is allowed to lessen his tax base by nominating deductions or by excluding certain income elements from his taxable income. Proportional tax rates when applied to lower-income classes will also be more progressive if such personal exemptions are declared.

Income measured over a given period may not necessarily come up with the most appropriate measure of taxpaying ability. For example, transitory rises in income might be saved, and in temporary declines in income a taxpayer might elect to finance consumption by taking from savings. Thus, if taxation is made comparable with “permanent income,” it can be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (with the exception of those on luxuries) are usually regressive, because the spread of individual income consumed or spent on a specific good lowers as the rate of personal income is raised. Poll taxes (also known as head taxes), nominated as a fixed amount per capita, patently are regressive.

It is hard to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden depends essentially on whether a national or a subnational (that is, provincial or state) tax is being debated.

In analysing the economic effects of taxation, it is important to differentiate between differing ideas of tax rates. The statutory rates will be specified in the law; usually these are marginal rates, but in some cases they are average rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income grows by one dollar. Hence, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature commonly contain graduated marginal rates—i.e., rates that rise as income increases. Heavy analysis of marginal tax rates must take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points more than nominated within the statutory rates. Since marginal rates signify how after-tax income increases or decreases in response to changes in before-tax income, they are the important ones for assessing incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applied to income from business and capital, as it may depend on such factors as 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 zero under a consumption-based tax.

Average income tax rates signify the fraction of total income that is required in taxation. The pattern of average rates is the one that is necessary for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises 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 other side of things, preferential treatment of income received fundamentally by high-income households may dwarf these effects, producing regressivity, as signified by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs put for projection systems are typically small reflective or transmissive panels set off by a bright arc lamp source. A series of lenses enlarges the reflected or transmitted image then casts it onto a screen. In front-projection systems the LCD is located on the side of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of greater cost and capability can use three separate LCD panels, forming separate red, green, and blue images that combine to form a coloured picture on the screen.

The growth in requirement for film presentations has granted a particular emphasis on the switching speed of liquid crystals. This has led to the creation of items using 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. Inside it the liquid crystal molecules are arranged in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and within the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a slight consequence of the optical activity and the angle of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. So, there must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The resultant 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 produced for larger passive-matrix presentations, but their cost and detail has hindered them from having any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as parts in projection systems or as viewfinders in digital cameras. Their fast reacting allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in fast succession (about 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state during the red and green periods and to a nontransmissive state in the blue period, having the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture pieces, the chair could be primary. While most of the other items (save for the bed) are created to support objects, the chair supports a human form. The term chair should be used here in the common sense, from stool to throne to further types like the bench or sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly defined.

The social history of the chair is as exciting as its history as an art and craft. The chair is not simply a physical support and an aesthetic artwork; it historically is a signifier of social ranking. In the old royal courts there were clear connotations between having a chair with arms, on a chair with a back but without arms, or worse having to make do with a stool. In the last century, the director’s or manager’s chair has risen iconic of superior standing, like in democratic governments the speaker sits on an elevated floor.

As its furniture purpose, the chair is employed for a variety of different purposes. There are chairs manufactured to suit man’s age and physical condition (the high chair, the wheelchair) and to denote his position in society (the executive chair, the throne). In historical times there were chairs used for birth (birth chairs); from the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our lifestyle has designated particular chairs for use in automobiles and aircraft. All of these chair forms has been perfected to conform to different human needs. For its significant relationship with man, the chair comes to its full significance only when utilised. Although it is not relevant to one’s appreciation of a cupboard or a dresser drawers whether there is anything inside or not, a chair is really seen and fairly tested with a person sitting on it, for chair and sitter complement the other. Thus the individual elements of a chair have been given labels likened to the limbs of a human form: arms, legs, feet, back, and seat.

Because the principal function of a chair is to support the human body, its worth is valued principally by how well it does fulfill this practical function. Within the manufacture of a chair, the chair maker is limited within certain static regulations and principal measurements. Within these regulations, however, the chair designer has great freedom.

The history of the chair extends over dates of several thousand years. There were peoples that had made individual chair types, seen of the premier task in the arenas of handling and creativity. Within these such civilisations, particular note should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of expert make, are now a finding from tomb findings. The first of the two 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 a designated animal, a curved seat, and leading to a sloping back supported above vertical stretchers. In this design a stable triangular design was crafted. There was apparently no noteworthy differentiation in the structure of Egyptian thrones and chairs for ordinary peasantry. The real change was in the level of ornamentation, in the particulars of pricier inlays. The Egyptian folding stool in all likelihood was created as an easily packed seat for officers. As a camp stool this chair continued til much later periods of time. But the stool also played the task of a ceremonial seat, its technical task as a folding stool neglected or forgotten. This can today be observed, 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 cannot be folded because the seats were created out of wood. The plain structure of the folding stool, consisting of two frames that spin on metal bolts and support a seat of leather or fabric set between them, then came again but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this form is the folding stool, made of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not from any ancient item still extant but as in a wealth of pictorial material. The iconic kind is the klismos displayed on the Hegeso Stele at the Dipylon burial area by Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs are visible. These strange legs were understood to be executed of bent wood and were in that case subjected to a large amount of pressure from the weight of the sitter. The joints attaching the legs to the frame of the seat were therefore very durable and were clearly denoted.

The Romans embued the Greek style; existing casts of seated Romans display examples of a heavier and apparently somewhat more crudely constructed klismos. Both styles, the light or heavy, were revived as part of the Classicist period. The klismos chair is used in French Empire chairs, in English Regency, and in particular kinds of considerable individuality in Denmark and Sweden circa 1800.

China
The ancestry of the chair in China cannot be traced as long as the progression of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed serial of sketches and paintings has been kept safe, with images of the interior and exterior of Chinese buildings and their furniture. Kept also from the 16th century are a trove of chairs made of wood or lacquered wood, that hold an astonishing resemblance to pictures of ancient chairs.

As was the case in Egypt, there existed two particular chair forms in China: a chair having four legs and a folding stool. This chair has been seen both with or without arms however never without the square seat and straight stiles (upright side supports) to support the back. In one kind, however, the stiles could be slightly curved above the arms in order to conform correctly to the structure of the S-shaped back splat (the main upright of the back). Each of the three limbs were mortised in the yoke-like top rail. Despite that the design of this back splat had an introduction for English chairs in the Queen Anne period, wooden members that would only to a restricted ability stabilise corner joints (as well as being loose into the bargain) represent a design exclusive to Chinese chairs. The four legs pass through the seat frame, which closes around the rounded staves. Every member is round in section or have rounded edges—acknowledging perhaps to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited form. These chairs demanded of the sitter to stay stiff and upright; for when too much weight is pushed on the back, the chair has a way of toppling over. In patriarchal Chinese homes of this period armchairs likely were reserved for elderly individuals, for they were greatly respected.

The Chinese folding stool is thought to have been brought to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is delicately held to the two legs of the stool by a curved member, which is more often than not designed with metal mounts. From a Western point of view the overall effect of both of these furniture styles is stylized. The manufacture and decoration parts are combined in a style that is all at once both naïve and refined. The patched up appearance is a result of the way that the individual items do not appear to have been fixed together by use of either glue or screws, but were mortised with one another and held in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its name on the chair. Paintings show a design of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to bring out a pattern of little pads. The front board and a corresponding board in the back could be folded after unscrewing some small iron hooks. Therefore the chair was an easily portable piece of furniture while traveling which, at the same time, held 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 the inside of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the design actually was instigated in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of thin shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in large amounts, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up along a wall. The style asserts itself with its harmonious 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 style—that was, to say, as progressed in Paris around 1750—conquered most of Europe and has been imitated or copied into the mid-20th century. The model owes this popularity to a combination of comfort and elegance. The seat adheres to the human body and allows 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 cover all the joints, which are constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them use wood of fairly thick density; but every member is deeply molded, all extraneous wood has been removed, and more expensive chairs might be further embellished with special delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all of the upholstery on the seat, back, and armrests; cane is in some cases used in place of upholstery.

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, 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 transactions of a business. Bookkeeping grants the figures from which accounts are written but is a different process, preliminary to accounting.

Basically, bookkeeping grants two kinds of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking placement in the entity within a particular time period.

Management officials, investors, and credit grantors all need to have this kind of information: management in order 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 about buying, holding, and selling securities; and credit grantors to assess the financial statements of an entity in deciding whether to accept a loan.

Pieces of financial and numerical records have been found for almost every country with a commercial backbone. Records of business contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The dual-entry style of bookkeeping came up with the progression of the commercial republics of Italy, and tutorial books for bookkeeping were developed within the 15th century in many Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial bookkeeping a requirement. The past of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in part, helped in shaping it. The international expansion of industrial and commercial activity needed more professional decision-making methods, which in turn needed higher sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government legislature became more important and resulted in higher demand for information; enterprising firms had to have available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the demand for bookkeeping for their own operations became higher.

Although bookkeeping procedures can be very multifaceted, all of it is based on two styles of books used in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and such), and the ledger has the information of individual accounts. The daily records in the journals are put in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are made from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to give an analysis of any changes that occurred in the entity equity due to the transactions of the period. The balance sheet shows the financial position of the enterprise at the particular point 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 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 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.
