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

The most common question customers ask when buying a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many brands and types available, it can be confusing for customers to pick between these technologies. It comes down to the fact that LCD projectors give better image quality and colour accuracy. The next part of this article will tell you why DLP projectors struggle with reproducing an equal grade of image quality.

Think of a set of blinds in your room for your bedroom window. By pulling 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 functions 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 operates to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the content reaches your screen is extremely significant in regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 separate 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 form the projector image. Something important to remember about LCD projectors is that all three colours are projected onto your projected surface simultaneously. The way a DLP projector functions is very 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 approach to forming 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 create 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 draw each coloured element of the image into a single whole image. In LCD projectors, all colours are available all the time to form the top level of brightness and fantastic colour accuracy. In DLP, only one colour is available at any given time, causing lower colour brightness and accuracy. Some DLP manufacturers have put a white segment in the colour wheel to improve overall brightness, but this further damages colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and thus must be better. 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 technology is capable of producing. DLP projectors do possess high contrast specifications as compared to a majority of LCD projectors. At a glance, this appears to be a benefit, however, in truth, the true black level is determined by the ambient light in the room when the projector is being utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you want to view requires moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most often seen artifact that a DLP projector forms 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 shone. LCD projectors do not have this problem because the colours are processed at the same time. DLP manufacturers have formed 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them impractical for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and they taught you how different colours of light refract different amounts when projected through the same lens. The downside with DLP projectors is that they have the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in different ways. Usually with a DLP projector, some yellow colour will come through above and a superfluous blue will be projected below an image as simple as a single black line. In building LCD projectors can be adjusted to minimize these effects on the projected image, because each colour is processed on separate LCD panels.

The sole real buy point (excluding price) with taking a DLP projector is its smaller total size and weight. However, this is only relevant with regard to mobility and must be traded off against the image benefits of LCD projectors. If overall picture quality is crucial to you, then the answer is no-brainer. Go for an LCD projector! LCD projectors will always show bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the initial yacht became a pleasure craft used mostly by royalty and then by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, coming out of private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty 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 then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), built more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting rose as popular with the wealthy and aristocracy, but after that point the fashion did not last.

The first yacht club in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with large naval panoply and gravity. The closest thing to racing boats was the “chase,” in which the “fleet” pursued an imagined enemy. The club went on, largely as a social club, until 1765, and in 1828, when merging with other clubs, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered manner on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been initiated at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continuing location of British yacht racing. The association at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for great bets were held, and the social life was lovely. Eventually Royal Yachting Club boats increased in size to over 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 power. Sailing was mostly for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first continuing American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The craft of bigger yachts was initially largely affected by the victory of America, which was designed by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its win at Cowes in 1851. The first yachts were not designed and built in the modern sense, with merely a model used. Not until the latter half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the design of sails and rigging what such science had already done for hulls.

Because most of all sailboats were individually built, there came a requirement for handicapping boats as this was previous to the one-design class boats were made. Thus, a rating rule was created, which is found in the International Rule, adopted in 1906 and revised in 1919. In the present day, one of the most rapidly blossoming areas in the sailing industry 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 elements (for an example of a two-person sailboat, see illustration). Racing for such boats can be had on an even par with no handicapping required. A great example is the uniform International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

So long as yachting was an activity mostly for the aristocracy and the wealthy, money was no object, and the size of boats grew, in both length and weight. The promotion and preference of smaller craft came in the second half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip 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 small boats. Following this in the 20th century, for the larger part after World War II, smaller racing and leisure craft became commonplace, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, at which point steam was set to replace sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly used in personal craft. Large power yachts were progressed to a high standard, and long-distance travel was a preferred occupation of the well off. The earliest power yachts were paddle-wheel boats; those then gave rise to yachts powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant craft, auxiliaries with both sail and power were the yacht standard for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were only power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of large steam yachts. Notably within these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of at least 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service during World War II.

As larger and more dependable internal-combustion engines were created, many big craft started using them for power. The creation of the diesel engine, with heavy oil for fuel, was furthered during World War I. During the decade following that, bigger power-yacht creation flourished, hitting a climax in the Orion (1930) at 3,097 tons. During that time the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power craft declined from 1932, and the style thereafter was for smaller, less costly yachts. From World War II, many small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a internationally beloved competition enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small recreational boats. The number of yachts and yachtsmen is increasing steadily, not only in the traditional places by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the placement of income and wealth. A proportional tax is the kind of tax that imposes the same relative requirement on each taxpayer—i.e., when tax liability and income grow in relative proportion. A progressive tax is characterized by a more than proportional increase in the tax liability in relation to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the comparative onus. Therefore, progressive taxes are seen as removing a lack of equality in income distribution, whereas regressive taxes might increase these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so for the upper-income group—particularly if a taxpayer is allowed to lower his tax base by nominating deductions or by excluding some particular income aspects from his taxable income. Proportional tax rates that are applied to lower-income groups can also be more progressive if such personal exemptions are claimed.

Income measured over a given year might not definitely offer the best measure of taxpaying status. For example, transitory rises in income could be saved, and within temporary declines in income a taxpayer may choose to provide for consumption by reducing savings. Ergo, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than when it is made comparable with annual income.

Sales taxes and excises (except those on luxuries) are mostly regressive, because the spread of own income consumed or spent for specific goods lowers as the level of personal income grows. Poll taxes (also called head taxes), levied as a fixed amount per capita, obviously are regressive.

It is difficult to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the 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 lays essentially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In considering the economic effects of taxation, it is relevant to differentiate between varied points of tax rates. The statutory rates will be dictated in legislation; usually these are marginal rates, but occasionally they are mean rates. Marginal income tax rates signify the fraction of incremental income demanded by taxation when income increases by one dollar. So, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature often contain graduated marginal rates—i.e., rates that grow as income rises. Heavy analysis of marginal tax rates are required to regard provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than specified within the statutory rates. Since marginal rates display how after-tax income changes 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 applicable to income from business and capital, because it may depend on factors such 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 nothing under a consumption-based tax.

Average income tax rates show the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is important 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 allowed for the taxpayer and dependents and also due to that marginal tax rates are graduated; conversely, preferential treatment of income received mostly by high-income households can dwarf these effects, allowing regressivity, as indicated by average tax rates that decrease as income grows.

The Development of Data Projectors

The LCDs used for projection systems are generally small reflective or transmissive panels illuminated by a strong arc lamp source. A number of lenses magnifies the reflected or transmitted image and casts it onto a screen. For front-projection systems the LCD is situated on the side of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of higher expense and performance may be found with three distinct LCD panels, casting separate red, green, and blue images that blend to create a coloured picture on the screen.

The growing requirement for pictographic displays has placed a growing emphasis on the switching speed of liquid crystals. This has required the creation of items using smectic liquid crystals, certain ones of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed smectic device. In it the liquid crystal molecules are managed in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as shown in the figure. The host liquid crystal holds optically active molecules, and a slight result of the optical activity and the tilt of the molecules is the presence 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. Therefore, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The corresponding change in optical properties can cause a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been produced for larger passive-matrix presentations, but their expense and intricacy has prevented them from making any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their quick reacting allows them to be employed 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 succession (around 100 cycles in a second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods but then to a nontransmissive state for the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture objects, the chair might be of most importance. While the majority of other items (save for the bed) are meant to support objects, the chair supports a human form. The term chair can be regarded here in the most general sense, from stool to throne to further items for example the bench and sofa, which can be considered 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 curious as its history as an art and craft. The chair is not just a physical support and/or an aesthetic object; it was also an indicator of social rank. At the old royal courts there were social signifiers between possessing a chair with arms, on a chair with a back but without arms, or having to utilise a stool. In the last century, a director’s and/or manager’s chair has been seen as a signifier of superior position, and even in democratic parliaments the speaker sits on a raised level.

As its furniture creation, the chair can be employed for a number of various forms. There are chairs manufactured to match man’s age and physical condition (the high chair, the wheelchair) and to connotate his rank in society (the executive chair, the throne). During past days there were chairs used for birthing (birth chairs); in 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. There are chairs that can be folded, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed new chairs for use in automobiles and aircraft. Each of these chair forms have been adapted to match to different human desires. Because of its unique importance with man, the chair exists to its full advantage only when utilised. Though it makes no difference to one’s appreciation of a cupboard or a chest of drawers if there might be things inside or not, a chair is understood and fairly evaluated with a person sitting in it, for chair and sitter suit the other. Thus the several areas of a chair have been named corresponding to the parts of our human parts: arms, legs, feet, back, and seat.

Because the obvious role of your chair is to support the body, its value is judged principally for how well it does fulfill this practical function. In the creation of a chair, the designer is bound by certain static rules and principal measurements. Under these rules, however, the chair designer has large freedom.

The history of the chair is an era of several thousand years. There is evidence of peoples that had made unique chair types, expressions of the foremost craft in the areas of technique and creativity. In such peoples, special note needs to 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 construct of skilled craft, are today seen from tomb discoveries. The first of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs shaped not unlike those of some animal, a curved seat, and a sloping back supported over vertical stretchers. From this design a durable triangular form was made. There seems to be no marked differentiation between the design of Egyptian thrones and chairs for common peasantry. The real change was in the complex ornamentation, in the selection of expensive inlays. The Egyptian folding stool probably was developed for an easily portable seat for army soldiers. As a camp stool the stool stayed around during much later periods. But the stool also then took on the character of a ceremonial seat, its mechanical function as a folding stool ignored or forgotten. This can from evidence be found, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but are not able to be folded because the seats were worked with wood. The simplistic structure of the folding stool, consisting of two frames that cycle on metal bolts and bear a seat of leather or fabric secured between them, can be seen at some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of those is the folding stool, made from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is known not as any ancient item still existing but as in a variety of pictorial objects. The best recognised is the klismos displayed on the Hegeso Stele at the Dipylon burial place near Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs could be visible. These unusual legs were likely to be executed of bent wood and were in that case had great pressure under the weight of the sitter. The joints holding the legs to the frame of the seat had to be therefore extremely durable and were particularly pointed out.

The Romans emulated the Greek chair; evidence of models of seated Romans offer designs of a heavier and which appear to be a kind of more crudely designed klismos. Both types, the light and heavy, were revived as part of the Classicist era. The klismos chair can be found in French Empire chairs, in English Regency, and in particular brands of marked iconicism within Denmark and Sweden around 1800.

China
The past of the chair in China is not able to be charted as well as the history of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) a full serial of drawings and artworks was preserved, showing the interior and exterior of Chinese buildings and the kinds of furniture. Preserved also of the 16th century are a collection of chairs of wood or lacquered wood, that hold an amazing similarity to representations of past chairs.

Same as in Egypt, there existed two iconic chair designs in China: a chair that had four legs and a folding stool. This four-legged chair has been seen both with and without arms but never without a square seat and straight stiles (upright side supports) to hold up the back. In one style, it has been found, the stiles could be marginally curved by the arms so as to conform correctly to the structure of the S-shaped back splat (the centre upright of the chairback). Together, all three areas were mortised onto the yoke-like top rail. Though the innovation of the back splat later had an influence on English chairs from the Queen Anne period, wooden sections that could merely to a limited extent support corner joints (and furthermore were loose as a result) represent a signature particular to Chinese chairs. The four legs are set through the seat frame, which finishes about the rounded staves. Every member is round in section or possesses rounded edges—acknowledging maybe to the bamboo tradition. The seat is not pleasant and had on occasion a plaited seat. These chairs demanded of the sitter to be stiff and upright; if too much pressure is exerted on the back, the chair has a way of toppling over. In patriarchal Chinese homes of this period armchairs likely were reserved only for the senior individuals in the family, for they were held in great esteem.

The Chinese folding stool is presumed to have taken to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is intricately held to the two legs of the stool in a curved member, which is generally seen with metal mounts. From a Western point of view the resultant effect of both of these furniture forms is stylized. The constructive and decorative elements are combined in a way that is both naïve and refined. The patched up appearance is an outcome of the manner that the individual items do not look to have been put together by means of either glue or screws, but had been mortised on one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its name on the chair. Paintings project a style of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of small pads. The front board and a corresponding board from the back could be folded after loosening some little iron hooks. Therefore the chair was an easily portable piece of furniture in traveling which, in the same time, gave the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be evidenced in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair can also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not held that the style actually started in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in considerable amounts, as can be seen from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up by a wall. The design asserts itself by its elegant proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, to say, as developed in Paris around 1750—spread over most of Europe and has been imitated or copied into the mid-20th century. The style owes its popularity to a combination of relaxation 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 tiny upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those employ wood of quite thick density; but each member is deeply molded, all extraneous wood has been removed, and more expensive chairs may be further embellished with very delicate and decorative carving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; canework is occasionally used in place of upholstery.

English chairs in the 18th century were more varied in style than the French. The French touch for stylistic uniformity, which spread from the highest circles in Paris and Versailles over most of France and was popularised 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 popular and was widely distributed throughout the world.

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

In cheaper 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, 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 function of a business. Bookkeeping gives the information from which accounts are drafted but is a previous process, required prior to accounting.

Essentially, bookkeeping finds two types of information: (1) the current value, or equity, of the entity and (2) the change in value—profit or loss—taking position in the business over a particular time.

Management officials, investors, and credit grantors all have to have this kind of 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 interpret the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors so as to assess the financial statements of an entity in finding whether to accept a loan.

Bits and pieces of financial and numerical recordkeeping are found for nearly every state with a commercial backbone. Records of commercial contracts have been discovered in the remains of Babylon, and accounts for both farms and estates had been held in ancient Greece and Rome. The two-entry manner of bookkeeping began with the furthering of the business republics of Italy, and tutorial manuals for bookkeeping were produced during the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a must-have. The ancestry of bookkeeping, in fact, closely reflects the history of commerce, industry, and government and, in some part, assisted shaping it. The global movement of industrial and commercial activity called for greater cosmopolitan decision-making procedures, which itself demanded higher sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government legislation became more detailed and resulted in increased need for information; business entities had to have information available to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the need for bookkeeping for their inner departmental operations went up.

Although bookkeeping procedures can be rather detailed, it is all based on two types of books used in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so on), and the ledger has the information of individual accounts. The daily records in the journals are entered in the ledgers.

Every month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to provide an analysis of the changes that took place in the enterprise equity resulting due to the events of the period. The balance sheet gives the financial condition of the entity at a particular point regarding 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 resulted in an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
