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

The most typical question asked when looking for a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many business brands and different models available, it can be challenging for consumers to make a choice between those technologies. It comes down to the fact that LCD projectors provide far superior image quality and colour accuracy. The following article explains why DLP projectors struggle with projecting the same rate of image quality.

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

How the light source is processed from when the projector turns on to when the content reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by cutting it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. A significant point to remember about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector operates is totally different and even how an image appears is not the same. With DLP, white light from the lamp is processed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s vision will then pull together each coloured element of the image into a single total image. In LCD projectors, all colours are available all the time to deliver the top level of brightness and superb colour accuracy. In DLP, just one colour is available at a time, resulting in lower colour brightness and accuracy. Some designers have included a white segment for the colour wheel to improve brightness generally, but this further detracts from colour accuracy.

I find in forums all the time that DLP gives a higher contrast ratio and ergo 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 system is capable of producing. DLP projectors do provide high contrast specifications as compared to many LCD projectors. At first glance, this can seem to be an advantage, however, in real life, the true black level is determined by the ambient light in the room when the projector is being utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you are trying to see needs moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most common 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 up between the time red, blue and green colours are projected. LCD projectors do not have this problem because the colours are projected at once. DLP manufacturers have developed 3DLP solutions using 3 chips to answer the colour break up error, but the price tag of these projectors make them not practical for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Remember back to high school science, and recall how different colours of light refract different amounts when projected through the same lens. The disadvantage with DLP projectors is that they utilise the one same panel with the same lens to project Red, Blue and Green. All 3 colours are different and refract light at different levels. Generally with a DLP projector, some yellow colour will appear above and a superfluous blue will come up below something as simple as a lone black line. During manufacturing LCD projectors can be set to remove these effects on the projected image, as each colour is directed on a separate LCD panels.

The only veritable benefit (excluding price) with picking a DLP projector is its overall smaller size and weight. However, this is only relevant in regard to portability and cannot be traded off against the image plusses of LCD projectors. If overall picture quality is vital to you, then the choice is no-brainer. Go for an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht was a leisure craft used initially by royalty and secondly by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private challenges. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure 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, sovereign 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting was found to be classy with the rich and nobility, but after that period the trend did not last.

The first yacht association in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had great naval panoply and gravity. The closest thing to a race was the “chase,” when the “fleet” pursued a fictional enemy. The club went on, mostly as a social club, until 1765, and in 1828, by conglomerating with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some stipulated manner 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 sovereignty in 1820, it came to be named 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 organisation had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the perpetual location of British yachting. The society at Cowes became the Royal Yachting Club, again at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing matches for great stakes were held, and the society life was lovely. Ultimately Royal Yachting Club boats grew 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 power. Sailing was largely for leisure and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The style of bigger yachts was initially largely put upon by the win of America, which was designed by George Steers for a syndicate led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its victory at Cowes in 1851. Earlier yachts were not designed and crafted in today’s sense, with only a model being used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the research of aerodynamics do for the design of sails and rigging what such study had earlier done for hulls.

Because most of all sailboats had to be individually custom-built, there came a desire for handicapping boats as this was before the one-design class boats were made. Therefore, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and revised in 1919. In modern times, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are manufactured to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be had on an even keel with no handicapping necessary. A great example is the generic International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

So long as yachting belonged primarily for the royal and the affluent, cost was no issue, and the size of boats grew, in both length and weight. The rise and preference of smaller yachts happened in the later 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 trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of less sizeable yachts. Later in the 20th century, for the larger part after World War II, smaller racing and leisure boats became commonplace, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam was set to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were used increasingly in leisure yachts. Large power yachts were furthered to a high degree, and long-distance sailing turned into a favoured occupation of the rich. The early power yachts were paddle-wheel boats; these then gave rise to boats powered by the wholly submerged screw or propeller sort of propulsion. As in the case of naval and merchant vessels, auxiliaries with both sail and power were the yacht standard for many years. By the latter half of the 20th century, many yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a push in the manufacture of large steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was operated 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 saw active service in World War II.

As bigger and more reliable internal-combustion engines were developed, many large boats began using them for power. The development of the diesel engine, with heavy oil for fuel, was furthered in World War I. From the decade after, big power-yacht building grew, hitting a climax in the Orion (1930) at 3,097 tons. In that time the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power yachts fell away from 1932, and the style after that was toward smaller, less costly boats. From World War II, a lot of small naval craft were sold to private owners for conversion to yachts. In the late 20th century, yachting is a internationally loved sport enjoyed by thousands of yachtsmen individually manning and maintaining their own small recreational boats. The number of yachts and owners has increased steadily, not only in the traditional areas by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the impact they have on the distribution of income and wealth. A proportional tax is one that places the same relative burden on each taxpayer—i.e., where tax liability and income grow in relative proportion. A progressive tax is characterizable by a more than proportional increase in the tax burden in relation to the rise in income, and a regressive tax is recognised by a less than proportional increase in the relative liability. Ergo, progressive taxes are viewed as removing inequalities in income distribution, while regressive taxes can cause an increase in these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so within the upper-income demographic—in particular if a taxpayer is permitted to reduce his tax base by declaring deductions or by taking some income parts from his taxable income. Proportional tax rates when applied to lower-income groups could also be more progressive if exemptions of a personal nature are declared.

Income measured over the period of a year may not necessarily come up with the best measure of taxpaying status. For example, transitory increases in income can be saved, and within temporary declines in income a taxpayer may select to finance consumption by reducing 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 (save on luxuries) tend to be regressive, because the share of one’s income consumed or spent on specific goods declines as the amount of personal income grows. Poll taxes (also known as head taxes), levied as a fixed amount per capita, obviously are regressive.

It is hard to classify 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 dictating who bears the tax burden lays crucially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In assessing the economic purpose of taxation, it is essential to distinguish between varied ideas of tax rates. The statutory rates are those specified in legislation; generally speaking these are marginal rates, but in some cases they are median rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income is increased by one dollar. Therefore, if tax onus grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws usually contain graduated marginal rates—i.e., rates that rise as income grows. Careful analysis of marginal tax rates should consider provisions as well as 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 greater than specified in the statutory rates. Since marginal rates specify how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for assessing incentive effects of taxation. It is even more complicated to know the marginal effective tax rate to apply to income from business and capital, as it may rely 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 nothing under a consumption-based tax.

Average income tax rates determine the fraction of total income that is taken in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually increase with income, both because personal allowances are permitted for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received mostly by high-income households could dampen these effects, producing regressivity, as displayed by average tax rates that fall as income increases.

The Development of Data Projectors

The LCDs built in projection systems are most often small reflective or transmissive panels lit up by a powerful arc lamp source. A line of lenses magnifies the reflected or transmitted image and then casts it onto a screen. In front-projection systems the LCD is situated on the same area of the screen as the viewer, although in rear-projection systems the screen is illuminated from behind. Projectors of more expense and capacity sometimes be found with three separated LCD panels, forming separate red, green, and blue images that come together to make a coloured image on the screen.

The growing demand for pictographic presentations has granted a growth in emphasis on the switching speed of liquid crystals. This has necessitated the creation of devices using smectic liquid crystals, particular kinds of which possess 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 layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are tilted, as displayed in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible result of the optical activity and the tilt 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 throughout 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 paired up to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been commercialized for larger passive-matrix presentations, but their expense and complexity has hindered them from enjoying any remarkable effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their immediate reacting allows them to be made use of in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in rapid speed (approximately 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods but then to a nontransmissive state in the blue period, having the upshot 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 may be the most important. While the majority of other forms (except the bed) are meant to support objects, the chair supports our human form. The term chair is meant to be viewed here in the most open sense, from stool to throne to further makes like a bench and sofa, which may be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly definitive.

The social history of the chair is as exciting as its history as an art and craft. The chair is not just a physical support and/or aesthetic item; it was historically an indicator of social standing. In the old royal courts there were clear differences between having a chair with arms, or a chair with a back but without arms, or having to use a stool. During the last century, a director’s and manager’s chair has become an identifier of superior standing, as well as in democratic government debate the speaker sits on an elevated level.

As its furniture form, the chair is employed for a variety of various purposes. There are chairs created to suit man’s age and physical condition (the high chair, the wheelchair) and to connotate his rank in society (the executive chair, the throne). From historical times there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs for ending life (the electric chair). There are 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 for easy storage, chairs on wheels, and chairs on runners.

Modern day living has demanded unique chairs for use in automobiles and aircraft. All these chair types has been adapted to suit to growing human requirements. Due to its significant link with man, the chair comes to its full advantage only when used. Though it is not relevant to one’s appreciation of a cupboard or a bureau if there might be anything inside or not, a chair is seen best and judged with a person sitting on it, for chair and sitter complement one another. Thus the various limbs of the chair have been labeled corresponding to the limbs of our human shape: arms, legs, feet, back, and seat.

Because the basic purpose of a chair is to support a human body, its worth is tested principally for how well it measures up to this practical use. In the structure of a chair, the maker is restricted within particular static rules and principal measurements. Inside these limitations, however, the chair maker has extensive freedom.

The history of the chair extended over an era of several thousand years. There are peoples that created unique chair forms, as seen of the highest work in the industries of skill and art. From these such peoples, a 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of expert scheme, are now a finding from tomb findings. The first one of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs crafted akin to those of a chosen animal, a curved seat, leading to a sloping back supported with vertical stretchers. In this design a durable triangular structure was crafted. There was in our understanding no notable variation in the construction of Egyptian thrones and chairs for typical non-royals. The real variation was in the level of ornamentation, in the choice of expensive inlays. The Egyptian folding stool in all probability was manufactured to be an easily packed seat for army officers. As a camp stool this chair persisted during much later points in time. But the stool then also took on the character of a ceremonial seat, its mechanical task as a folding stool fast forgotten. This can from today’s evidence be noted, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the form of folding stools but can’t be folded as the seats were created of wood. The easy construction of the folding stool, consisting of two frames that turn on metal bolts and support a seat of leather or fabric held between them, came again somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of these is the folding stool, of ashwood, found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not in any ancient item still in form but seen in a variety of pictorial evidence. The best known is the klismos depicted on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs would be shown. These unusual legs were probably created of bent wood and were thus bore great pressure under the weight of the sitter. The joints securing the legs to the frame of the seat are therefore very stable and were visibly denoted.

The Romans embued the Greek designs; designs of casts of seated Romans display evidence of a denser and are a somewhat less delicately crafted klismos. Both features, the light and heavy, were seen again within the Classicist time. The klismos style is used in French Empire furniture, in English Regency, and in some particular kinds of considerable originality within Denmark and Sweden during 1800.

China
The past of the chair in China cannot be charted as far back as the progression of the chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged folio of images and works of art was protected, showing the insides and outer parts of Chinese homes and the furniture. Preserved also since the 16th century are some chairs crafted from wood or lacquered wood, that possess an intriguing familiarity to designs of older chairs.

As were the designs in Egypt, two chair forms dominated in China: a chair of four legs and a folding stool. This chair was constructed both with and without arms although always with a square seat and straight stiles (vertical side supports) to hold up the back. In one style, it must be said, the stiles could be delicately curved over the arms for the purpose of suit the structure of the S-shaped back splat (the centre upright of its chairback). The three parts are mortised on the yoke-like top rail. Though the style of the Chinese back splat later had an inspiration for English chairs from the Queen Anne period, wooden members that just to a limited capability support corner joints (as well as being loose in the bargain) indicate an element particular to Chinese chairs. The four legs pass through the seat frame, which finishes about the rounded staves. All the members are round in section or has rounded edges—acknowledging as may be to the bamboo tradition. The seat is not comfortable and had on occasion a plaited texture. These chairs required the sitter to stay stiff and upright; when too much weight is pushed on the back, the chair has a way of falling over. In patriarchal Chinese households of this epoch armchairs probably were only for older individuals in the family, for they were held in great respect.

The Chinese folding stool is thought to have come to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is delicately joined to the two legs of the stool by use of a curved member, which is generally provided with metal mounts. From a Western understanding the resultant effect of these two furniture items is stylized. The structure and decoration issues are combined in a style that is all at once both naïve and refined. The piecemeal appearance is a result of the fact that the individual members do not appear to have been adjoined by either glue or screws, but had been mortised onto one another and fixed in its place in the manner of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered style of chair is displayed in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair might also be found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not held that the design actually was born in The Netherlands. Usually, the legs of the chair will be smooth, round in section, and of slim dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was produced in considerable quantities, as surmisable from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up by a wall. The form asserts itself by virtue of its elegant proportions and expensive upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, as developed in Paris around 1750—disseminated through most of Europe and has been imitated or copied during the mid-20th century. The style owes this popularity to a combination of relaxation and elegance. The seat conforms to the human body and permits 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 found between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike principles in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those are made from wood of fairly thick dimensions; but each member is deeply molded, all extra wood has been removed, and more expensive examples might be further embellished with highly delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for the upholstery on the seat, back, and armrests; canework is sometimes used rather than upholstery.

English chairs from the 18th century were more differentiated in design than the French. The French manner for stylistic uniformity, which disseminated from the royal circles in Paris and Versailles within most of France and became the favourite in many parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became reknowned and was widely distributed throughout the world.

Late 18th to 20th century
During the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

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

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

Basically, bookkeeping provides two parts of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking place in the business over a given period of time.

Management officials, investors, and credit grantors all demand such information: management to analyse the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the upshot of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an entity in judging whether to grant a loan.

Pieces of financial and numerical recordkeeping are uncovered for just about every state with a commercial background. Records of commercial contracts have been uncovered in the remains of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The dual-entry way of bookkeeping came with the furthering of the enterprising republics of Italy, and tutorial books for bookkeeping were developed during the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial books a paramount factor. The history of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, in some part, assisted forming it. The worldwide movement of industrial and commercial activity demanded higher sophisticated decision-making processes, which then demanded more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more significant and resulted in even greater demand for information; business firms had to provide information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for their own operations increased.

Though bookkeeping methodology can be very detailed, it is all based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, etcetera), and the ledger must have the information of individual accounts. The daily records in the journals are put in the ledgers.

Every month, by general practice, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to display an analysis of the changes that took place in the entity equity from the events of the period. The balance sheet provides the financial position of the corporation at the particular point in time 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.
