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

The common question customers ask when buying a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most popular projector imaging technologies. With so many business brands and types available, it can be confusing for the buyer to make a decision between both technologies. The simple fact of the matter is that LCD projectors give superior image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up an equal rate of image quality.

Think of a set of blinds in your household over your bedroom window. By a twist of a rod you can make the shutters open or closed, depending on if you want to let light in or not. This is exactly how an LCD projector operates. Each pixel operates like its own shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point at which the projector is turned on to when the content reaches your screen is extremely significant with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting 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 create the elements of the image by shining each pixel on and off. The pixels are then combined in a glass prism to create the projector image. Something important to know about LCD projectors is that all three colours are projected onto your screen at once. The way a DLP projector operates is totally different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is processed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming an image casts a sequence of red, blue and green light. The millions of micro mirrors as described 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 eye will then put together each coloured element of the image into the whole image. With LCD projectors, all colours are available all the time to form the best brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, causing lower colour brightness and accuracy. Some manufacturers have put a white segment for the colour wheel to improve brightness generally, but this goes and detracts from colour accuracy.

I see in forums all the time that DLP has a higher contrast ratio and therefore must be better quality. For those who are uncertain, 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 provide high contrast specifications when compared to many LCD projectors. Initially, this can seem to be a plus, however, in reality, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to view requires moving images, DLP projection technology also has image imperfections, or ‘artifacts’. The most commonplace artifact that a DLP projector displays with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images keep changing between the time red, blue and green colours are projected. LCD projectors do not have this characteristic because every colour is delivered at the same time. DLP manufacturers have created 3DLP solutions using 3 chips to resolve the colour break up error, but the expense of these projectors make them not practical for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how various colours of light refract differing amounts when directed through the same lens. The disadvantage with DLP projectors is that they use the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Usually with a DLP projector, some extra yellow colour will show above and some extra blue will be projected below an image of something as simple as a single black line. During manufacturing LCD projectors can be fixed to take away these effects on the projected image, because each colour is projected on isolated LCD panels.

The one true advantage (excluding price) with going with a DLP projector is its overall smaller size and weight. However, this is only relevant for mobility and cannot be traded off against the image advantages of LCD projectors. If the outcome of the picture quality is vital to you, then the solution is a no-brainer. Take an LCD projector! LCD projectors will definitely make bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the first yacht was a pleasure craft used mostly by royalty and secondly by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty 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 named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting became fashionable for the rich and aristocracy, but after that period the fashion did not last.

The first yacht group in the British Isles, the Water Club, was formed at about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and held large naval panoply and rigour. The closest thing to racing was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, after conglomerating with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized method on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to monarchy in 1820, it was then called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, 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 patronage made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British racing. The club at Cowes became the Royal Yachting Club, also at the accession of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing races for high bids were held, and the club life was lovely. Ultimately Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English gained control. Sailing was for the most part for fun and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a benchmark of luxury and sophistication for the later yachts in those waters 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 aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The style of large yachts was first greatly affected by the win of America, which was drawn by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its victory at Cowes in 1851. Early yachts were not designed and built in a contemporary sense, with just a model used. Not until the second half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the application of the science of aerodynamics do for the craft of sails and rigging what such science had earlier done for hulls.

Because most of all sailboats had to be individually manufactured, there came a need for handicapping boats previous to the one-design class boats were built. Thus, a rating rule was decreed, which ended up in the International Rule, adopted in 1906 and edited in 1919. Today, one of the rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between those boats can be had on an even par with no handicapping required. A prime example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting was done largely for the aristocracy and the rich, cost was no object, and the size of boats increased, in both length and weight. The promotion and preference of smaller boats happened in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Thereafter in the 20th century, particularly after World War II, smaller racing and recreational craft became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, at which point steam was set to take the place of sail power in market craft, the steam engine, and later the internal-combustion engine, were employed increasingly in personal boats. Sizeable power yachts were progressed to a high element, and long-distance sailing was a favoured occupation of the affluent. The earliest power yachts were paddle-wheel boats; they then gave rise to those powered by the fully submerged screw or propeller type of propulsion. Like naval and merchant boats, auxiliaries possessing both sail and power were the yacht standard for a number of years. By the later half of the 20th century, several yachts were still auxiliaries, but the larger part were solely power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the manufacture of bigger steam yachts. Conspicuous within 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, bought 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 dependable internal-combustion engines were produced, many large yachts were using them for power. The development of the diesel engine, using heavy oil for fuel, was furthered during World War I. During the decade that followed, bigger power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. From that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power yachts lessened in 1932, and the fashion after that was for smaller, less costly craft. Following World War II, many small naval craft were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a internationally beloved activity enjoyed by thousands of yachtsmen individually sailing and keeping their own small pleasure boats. The number of yachts and owners is increasing steadily, not only in the traditional places along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the impact they have on the placement of income and wealth. A proportional tax is a kind that imposes the same relative burden on each taxpayer—i.e., where tax liability and income move in the same scale. A progressive tax is characterized by a more than proportional rise in the tax onus in regard to the growth in income, and a regressive tax is characterizable by a less than proportional rise in the comparative burden. So, progressive taxes are seen as reducing inequity in income distribution, but regressive taxes can increase these inequalities.

The taxes that are generally believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so for the upper-income group—especially if a taxpayer is permitted to lower his tax base by nominating deductions or by leaving out some certain income aspects from his taxable income. Proportional tax rates if applied to lower-income demographics will also be more progressive if such personal exemptions are made.

Income measured over the period of a year does not definitely give the best measure of taxpaying requirement. For example, transitory growth in income can be saved, and in temporary declines in income a taxpayer may select to pay for consumption by taking from savings. Thus, if taxation is made comparable along with “permanent income,” it will be less regressive (or more progressive) than if it is made comparable with annual income.

Sales taxes and excises (excepting luxuries) are usually regressive, because the share of personal income consumed or spent on specific goods decreases as the level of personal income increases. Poll taxes (aka head taxes), levied as a set amount per capita, patently are regressive.

It is complicated to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden depends for the most part on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effects of taxation, it is important to differentiate between varied ideas of tax rates. The statutory rates are nominated in legislature; commonly these are marginal rates, but for some cases they are median rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income increases by one dollar. Ergo, if tax onus rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that grow as income grows. Careful analysis of marginal tax rates must regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points higher than specified in the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for assessing incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate to apply to income from business and capital, because it may be reliant on considerations 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 display the part of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates generally increase with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households can dampen these effects, forcing regressivity, as shown by average tax rates that lower as income grows.

The Development of Data Projectors

The LCDs built for projection systems are usually small reflective or transmissive panels set off by a powerful arc lamp source. A number of lenses magnifies the reflected or transmitted image and then sends it onto a screen. For front-projection systems the LCD is situated on the same area of the screen as the viewer, but in rear-projection systems the screen is illuminated from behind. Projectors of more expense and performance sometimes have three discrete LCD panels, creating separate red, green, and blue images that mesh to reflect a coloured display on the screen.

The growth in demand for pictographic presentations has had a growth in emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items utilizing smectic liquid crystals, some types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most complex smectic device. Inside it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are slanted, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a minor consequence of the optical activity and the shape 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 must be a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the 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 create a change from light to dark if one or more polarizers are employed.

SSFLC devices have been commercialized for larger passive-matrix displays, but their expense and detail has hindered them from making any great 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 reaction allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast succession (about 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods but to a nontransmissive state during the blue period, creating the upshot 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 could be paramount. While most other items (apart from the bed) are intended to support objects, the chair supports the human form. The term chair must be viewed here in the general sense, from stool to throne to developed pieces for example a bench and sofa, which might be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously definitive.

The social history of the chair is as stimulating as its history as a creative craft. The chair is not just a physical support or aesthetic item; it historically is an indicator of social hierarchy. At the Medieval royal courts there were important differences between possessing a chair with arms, sitting on a chair with a back but without arms, or worse having to make do with a stool. During the recent century, the director’s and manager’s chair has been regarded as an indicator of superior dignity, as well as in democratic governments the speaker sits on an elevated level.

In its furniture form, the chair is utilised for a range of various models. There are chairs manufactured to fit man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). From the olden days there were chairs for births (birth chairs); from the 20th century, there have been chairs used 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 have chairs that can be folded, chairs on wheels, and chairs on runners.

Our lifestyle has demanded special chairs for automobiles and aircraft. Every one of these chair types has perfected to conform to evolving human desires. Because of its unique connection with man, the chair comes to its full advantage only when being used. While it doesn’t make any difference to one’s appreciation of a cupboard or a bureau if there is anything inside or not, a chair is best seen and fairly evaluated with a person sitting in it, because chair and sitter complement each other. Thus the various parts of the chair are given labels according to the elements of our human parts: arms, legs, feet, back, and seat.

Because the original function of the chair is to support the human body, its value is judged principally by how well it does fulfill this practical job. Within the structure of a chair, the carpenter is restricted under the static law and principal measurements. Within these boundaries, however, the chair creator has marvellous freedom.

The history of the chair was an era of several thousand years. There is evidence of cultures that created iconic chair types, as expressions of the topmost task in the spheres of technique and art. Within such civilisations, special mention 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of masterful make, were known from findings made in tombs. One 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 a chosen animal, a curved seat, with a sloping back supported above vertical stretchers. From this a strong triangular form was created. There was to all appearances no noteworthy change between the design of Egyptian thrones and chairs for common citizens. The simple variation lied in the intricacy of ornamentation, in the choice of pricier inlays. The Egyptian folding stool most likely was manufactured for an easily carried seat for army. As a camp stool the chair persevered for much later points in time. But the stool then existed in the use of a ceremonial seat, its original history as a folding stool simply forgotten. This can from 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 were in the form of folding stools but cannot be folded as the seats were made of wood. The simple manufacture of the folding stool, composed of two frames that cycle on metal bolts and hold a seat of leather or fabric fastened between them, then came again some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of those is the folding stool, from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not with any ancient item still existing but as in a variety of pictorial evidence. The most well known is the klismos seen on the Hegeso Stele at the Dipylon burial ground just out of Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs would be displayed. These curved legs were most likely to have been executed out of bent wood and were as such bore great pressure under the weight of the sitter. The joints joining the legs to the frame of the seat would have had to be therefore extremely strong and were particularly pointed out.

The Romans adopted the Greek designs; existing casts of seated Romans are examples of a denser and in appearance somewhat less intricately built klismos. Both designs, the light and the heavy, were revived during the Classicist epoch. The klismos style can be seen in French Empire chairs, in English Regency, and in some special forms of considerable individuality of Denmark and Sweden circa 1800.

China
The progression of the chair in China is not able to be charted as far back as that of Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged series of images and paintings was kept safe, displaying the interior and outside of Chinese houses and the furniture. Also kept from the 16th century are some chairs crafted from wood or lacquered wood, that hold an astonishing resemblance to pictures of ancient chairs.

As was the case in Egypt, two particular chair forms existed in China: a chair of four legs and a folding stool. This chair is found both with and without arms however never missing the square seat and straight stiles (standing side supports) to give support to the back. In one kind, it has been found, the stiles were delicately curved on top of the arms for the purpose of sit correctly with the form of the S-shaped back splat (the centre upright of the back). Each of the three parts were mortised on the yoke-like top rail. Despite that the design of a back splat exercised an influence on English chairs during the Queen Anne period, wooden items that could merely to a limited capability embolden corner joints (and are loose in the result) indicate an element solely to Chinese chairs. The four legs sit through the seat frame, which closes over the rounded staves. All the members are round in section or possesses rounded edges—acknowledging maybe to the bamboo tradition. The seat is not pleasant and occasionally had a plaited texture. These chairs required the sitter to remain stiff and upright; when too much pressure is pushed on the back, the chair has a tendency to fall. In patriarchal Chinese households of this era armchairs most likely were only for older members of the family, for they were respected greatly.

The Chinese folding stool is thought to have come to China from the West. It does not differ much from the Egyptian or Scandinavian folding stools, but it possesses a difference in that the top rail is prettily fixed to the two legs of the stool with a curved member, which is usually seen with metal mounts. From a Western perspective the resultant effect of both of these furniture styles is stylized. The constructive and decoration parts are combined in a manner that is both naïve and refined. The patched up appearance is a result of the fact that the individual items do not look to have been joined together by either glue or screws, but have been 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 mark on the chair. Artworks display 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, stitched to produce a pattern of small pads. The front board and a corresponding board in the back could be folded after loosening some small iron hooks. Thus the chair was a readily portable piece of furniture while traveling which, at the same time, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be seen in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair is also found in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not certain that the innovation actually originated in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slender shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in considerable numbers, as indicated from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up by a wall. The form asserts itself by virtue of its elegant proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, to say, as created in Paris around 1750—spread through most of Europe and has been imitated or copied in the mid-20th century. The design owes this popularity to a combination of comfort and delicacy. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are achieved between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of fairly thick measurements; but all the members are deeply molded, all extraneous wood has been taken away, and finer examples would be further embellished with very delicate and decorative woodwork. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for the upholstery on the seat, back, and armrests; canework is in some cases used in place of upholstery.

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, suggest that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the charting of the money values of the operation of a business. Bookkeeping creates the figures from which accounts are made but is a different process, required prior to accounting.

Essentially, bookkeeping grants two types of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking placement in the enterprise within a given period of time.

Management officials, investors, and credit grantors all have to have this information: management to interpret 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 so as to judge the financial statements of an enterprise in judging whether to accept a loan.

Evidence of financial and numerical recordkeeping have been uncovered for just about every group of people with a commercial backbone. Records of business contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The two-entry way of bookkeeping came up with the development of the commercial republics of Italy, and instruction manuals for bookkeeping were created within the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial bookkeeping a necessity. The past of bookkeeping, in fact, closely reflects the past of commerce, industry, and government and, in part, assisted shaping it. The worldwide revolution of industrial and commercial activity demanded better sophisticated decision-making methods, which itself demanded more sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government regulation became more significant and resulted in even greater demand for information; firms had to have information available to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the requirement for bookkeeping for their own inner operations increased.

While bookkeeping methods can be very multifaceted, it is all based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger must have the information of individual accounts. The daily records kept in the journals are put in the ledgers.

Each month, generally, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to provide an analysis of those changes that occurred in the ownership equity as a result of the operations of the period. The balance sheet gives the financial situation of the enterprise at the particular point taken from 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. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
