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

The typical question customers ask when purchasing 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, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many company brands and models available, it can be confusing for consumers to choose between these technologies. It comes down to the fact that LCD projectors provide far better image quality and colour accuracy. The next paragraph will explain why DLP projectors struggle with projecting a comparable grade of image quality.

Visualise a set of blinds in your household covering your bedroom window. By twisting a rod you can turn the shutters open or closed, depending on if you want to let light in or not. That is exactly how an LCD projector behaves. Each pixel functions like an individual shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as professionals 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 ultimately significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which send the coloured light to 3 individual LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. A significant point to remember about LCD projectors is that all three colours are sent onto your projected surface all at once. The way a DLP projector functions is widely different and even the way an image appears is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image forms a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce 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 pull together each coloured element of the image into a single total image. From LCD projectors, all colours are available all the time to create the top level of brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, and so causing lower colour brightness and accuracy. Some DLP manufacturers have placed a white segment into the colour wheel to improve overall brightness, but this then degrades colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and as such must be better quality. For those who don’t 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 system is capable of. DLP projectors do provide high contrast specifications compared to a majority of LCD projectors. At first glance, this appears to be a plus, however, in reality, the true black level is determined by the ambient light in the room when the projector is in use. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to project requires moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images keep changing between the time red, blue and green colours are pulled up. LCD projectors do not have this downside because every colour is processed simultaneously. DLP developers have formed 3DLP solutions using 3 chips to solve the colour break up issue, but the price of these projectors make them not practical for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and remember when they taught you how the various colours of light refract various amounts when shone through the same lens. The downside with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in different ways. Often with a DLP projector, an extra yellow colour will come up above and some extra blue will show below an image containing something as simple as a straight black line. In manufacturing LCD projectors can be adapted to reduce these effects on the projected image, because each colour is projected on its own LCD panels.

The only veritable benefit (excluding price) with choosing a DLP projector is its smaller total size and weight. However, this is only relevant with regard to mobility and has to be traded off against the image advantages of LCD projectors. If overall picture quality is important to you, then the choice is simple. Choose an LCD projector! LCD projectors will always show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the early yacht was a leisure craft used initially by royalty and secondly by the burghers for the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private challenges. 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 gave him a 20-metre (66-foot) leisure 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, sovereign 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting was found to be popular among the wealthy and aristocracy, but after that point the trend did not last.

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

Yacht racing began in some ordered manner on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht club had been started 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 continued site of British yachting. The association at Cowes became the Royal Yachting Club, again at the rise of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for high bets were held, and the social life was wonderful. It came to be that the Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English took dominance. Sailing was mostly for leisure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a benchmark of luxury and elegance for the later yachts in that area from the late 19th century. The first enduring American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of sizeable yachts was originally largely put upon by the win of America, which was created by George Steers for a group led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. Earlier yachts were not designed and manufactured in today’s sense, with only a model used. Not until the later 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 study had already done for hulls.

Because most of all sailboats had been individually built, there arose a desire for handicapping boats before the one-design class boats were built. Therefore, a rating rule was decreed, which resulted in the International Rule, accepted in 1906 and amended in 1919. In the present day, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are built to the same requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be done on an even basis with no handicapping at all. A great example is the uniform International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

As long as yachting was an activity largely for the aristocracy and the affluent, money was no issue, and the size of boats grew, in both length and weight. The rise and desire of smaller craft happened in the second 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of smaller craft. Following this in the 20th century, notably after World War II, smaller racing and leisure boats became more common, down to the dinghy, a preferred 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
After the decade 1840–50, during which steam was set to emulate sail power in public vessels, the steam engine, and later the internal-combustion engine, were employed increasingly in personal vessels. Sizeable power yachts were developed to a high degree, and long-distance sailing turned into a preferred occupation of the well off. The earliest power yachts were paddle-wheel boats; those then made way to boats powered by the wholly submerged screw or propeller type of propulsion. As in the case of naval and merchant craft, auxiliaries possessing both sail and power were the yacht standard for several years. By the latter half of the 20th century, many yachts were still auxiliaries, but the large part were exclusively power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the construction of more sizeable steam yachts. Conspicuous of 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 at least 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 for World War II.

As larger and better quality internal-combustion engines were produced, many large boats were using them for power. The development of the diesel engine, employing heavy oil for fuel, advanced in World War I. From the decade that followed, bigger power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. In that period the best auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power yachts declined from 1932, and the trend thereafter was in preference of smaller, less costly yachts. From World War II, a lot of small naval craft were traded by private owners for conversion to yachts. At the late 20th century, yachting had become a internationally popular competition enjoyed by thousands of yachtsmen who are actually owning and maintaining their own small recreational craft. The number of boats and yachtsmen is increasing steadily, not only in the traditional places 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 the kind that applies the same relative onus on all the taxpayers—i.e., when tax liability and income increase in relative proportion. A progressive tax is characterized by a greater than proportional increase in the tax liability relative to the increase in income, and a regressive tax is recognisable by a less than proportional rise in the related onus. Thus, progressive taxes are thought of as taking away the lack of equality in income distribution, while regressive taxes are seen to have the result of increasing these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so within the upper-income class—particularly if a taxpayer is allowed to reduce his tax base by nominating deductions or by taking particular income aspects from his taxable income. Proportional tax rates if applied to lower-income classes would also be more progressive if exemptions of a personal nature are made.

Income measured over a given period may not absolutely offer the most suitable measure of taxpaying requirement. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may choose to pay for consumption by reducing savings. Therefore, if taxation is compared with “permanent income,” it should be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (with the exception of those on luxuries) tend to be regressive, because the spread of one’s income consumed or spent for a specific good declines as the level of personal income increases. Poll taxes (also termed head taxes), calculated as a flat amount per capita, patently are regressive.

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

In regarding the economic effects of taxation, it is relevant to differentiate between various points of tax rates. The statutory rates include those nominated in law; generally speaking these are marginal rates, but in some cases they are average rates. Marginal income tax rates note the fraction of incremental income demanded by taxation when income rises by one dollar. Thus, if tax burden grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislation generally contain graduated marginal rates—i.e., rates that increase as income rises. Structured analysis of marginal tax rates should regard provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than indicated 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 appropriate ones for assessing incentive effects of taxation. It is even more complicated to nominate the marginal effective tax rate applied to income from business and capital, since it may be dependant on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates display the fraction of total income that is required in taxation. The pattern of average rates is the one that is relevant for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally increase with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households can swamp these effects, allowing regressivity, as indicated by average tax rates that decrease as income increases.

The Development of Data Projectors

The LCDs put for projection systems are typically small reflective or transmissive panels illuminated by a strong arc lamp source. A number of lenses enlarges the reflected or transmitted image and then casts it on the screen. For front-projection systems the LCD is set on the same side of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of greater cost and capacity might be found with three separate LCD panels, reflecting separate red, green, and blue images that mesh to make a coloured picture on the screen.

The growth in demand for visual presentations has placed a particular emphasis on the switching speed of liquid crystals. This has led to the manufacture of items using smectic liquid crystals, particular types of which possess a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. Within it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and within the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible consequence 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. So, there is a permanent charge separation across 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 therefore reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been publicized for large passive-matrix displays, but their expense and detail has prevented them from creating any particular progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as elements in projection systems or as viewfinders in digital cameras. Their fast response allows them to be utilised in time-sequential colour systems, in which high cost colour filters are removed for a coloured backlight that flashes red, green, and blue in rapid pace (approx 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state during the red and green periods and to a nontransmissive state during the blue period, creating the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture objects, the chair might be of the most importance. While many other objects (save for the bed) are meant to support objects, the chair supports the human form. The term chair must be used here in the widest sense, from stool to throne to derivative items including a bench or sofa, which should be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinuishable.

The social history of the chair is as stimulating as its history as a creative art. The chair is not merely a physical support or an aesthetic artwork; it is also a signifier of social rank. From the historical royal courts there were important differences between being seated on a chair with arms, on a chair with a back but no arms, or worse having to use a stool. From the last century, a director’s and manager’s chair has developed a symbol of superior position, as well as in democratic parliaments the speaker sits on a high-set platform.

As a furniture form, the chair ranges from a variety of different makes. There are chairs manufactured to suit man’s age and physical condition (the high chair, the wheelchair) and to denote his standing in society (the executive chair, the throne). In the olden days there were chairs for births (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). There are chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has derived special chairs for automobiles and aircraft. All these chair types has been changed to conform to different human requirements. Because of its significant connection with man, the chair appears to its full purpose only when being utilised. Though it doesn’t make a difference to one’s appreciation of a cupboard or a dresser drawers whether there might be anything inside or not, a chair is understood best and regarded best with a person utilising it, for chair and sitter require each other. Thus the different limbs of the chair have been named according to the names of a human shape: arms, legs, feet, back, and seat.

Because the primary work of the chair is to support a body, its value is tested basically on how well it measures up to this practical role. In the design of the chair, the designer is restricted in particular static legislation and principal measurements. In these boundaries, however, the chair creator has marvellous freedom.

The history of the chair lasted over a period of several thousand years. There existed cultures that created significant chair shapes, expressions of the highest endeavour in the areas of skill and art. In those cultures, individual note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of expert scheme, are today a finding from tomb findings. The first of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs structured not unlike those of some animal, a curved seat, with a sloping back supported from vertical stretchers. From this design a durable triangular design was created. There seemed to be no significant variation in the structure of Egyptian thrones and chairs for common non-royals. The simple difference was in the intricacy of ornamentation, in the choice of more expensive inlays. The Egyptian folding stool most probably was crafted for an easily packed seat for army. As a camp stool the stool stayed until much later points. But the stool also played the character of a ceremonial seat, its original role as a folding stool being forgotten. This can already be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are made in the form of folding stools but cannot be folded because the seats were made out of wood. The plain build of the folding stool, being of two frames that turn on metal bolts and have a seat of leather or fabric fastened between them, appeared at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this type is the folding stool, crafted out of ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not with any ancient fossil still existing but from a trove of pictorial material. The better recognised is the klismos seen on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs are displayed. These curving legs were presumed to have been executed in bent wood and were as such bore huge pressure with the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very strong and were particularly denoted.

The Romans embued the Greek designs; existing statues of seated Romans are examples of a heavier and which appear to be a kind of less delicately constructed klismos. Both types, light or heavy, were revived during the Classicist period. The klismos influence is evidenced in French Empire design, in English Regency, and in some special forms of profound individuality within Denmark and Sweden circa 1800.

China
The progression of the chair in China cannot be followed as long as the ancestry of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an undamaged series of sketches and artworks has been preserved, showing the interiors and outside of Chinese households and their furniture. Also kept of the 16th century are some chairs made from wood or lacquered wood, that bear an amazing likeness to representations of ancient chairs.

Same as in Egypt, there were two iconic chair designs in China: a chair that had four legs and a folding stool. That chair was found both with and without arms but never without its square seat and straight stiles (vertical side supports) to hold up the back. In one type, it has been found, the stiles are slightly curved by the arms to sit correctly with the shape of the S-shaped back splat (the central upright of its back). Together, all three areas are mortised in the yoke-like top rail. While the innovation of the Chinese back splat later had an influence on English chairs during the Queen Anne period, wooden pieces that would only to a particular limit reinforce corner joints (and were loose into the bargain) signify a design signatory to Chinese chairs. The four legs sit through the seat frame, which stops upon the rounded staves. All the members are round in section or has rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is uncomfortable and may have had a plaited bottom. These chairs required of the sitter to stay stiff and upright; for when too much pressure is exerted on the back, the chair has a way of collapsing. In patriarchal Chinese households of this era armchairs most likely were allowed only for older members of the family, for they were held in great respect.

The Chinese folding stool is believed to have taken to China from the West. It is akin so very much from the Egyptian or Scandinavian folding stools, but it possesses a difference in that the top rail is delicately held to the two legs of the stool by use of a curved member, which is often designed with metal mounts. From a Western understanding the resulting effect of these two furniture forms is stylized. The structure and decoration elements are combined in a style that is all at once naïve and refined. The patched up appearance is a result of the manner that the individual parts do not appear to have been adjoined by means of either glue or screws, but have been mortised into one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its signature on the chair. Works of art project a type of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in between, stitched to show up a pattern of little pads. The front board and a related board in the back could be folded after loosening some little iron hooks. Therefore the chair was a portable piece of furniture while traveling which, during the same period, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is displayed in engravings of the inside of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not held that the form actually originated in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in considerable quantities, as surmisable from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up against a wall. The form asserts itself with 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 is, as developed in Paris around 1750—disseminated through most of Europe and has been imitated or copied during the mid-20th century. The design owes the popularity to a combination of relaxation and delicacy. The seat suits 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 little upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back cover all the joints, which are constructed solidly on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are constructed from wood of quite thick density; but each member is deeply molded, all extraneous wood has been taken away, and more expensive chairs can be further embellished with special delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all the upholstery on the seat, back, and armrests; cane is sometimes used in place of upholstery.

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

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

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

In cheaper styles 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, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping grants the numbers from which accounts are drafted but is a previous process, prerequisite to accounting.

Fundamentally, bookkeeping provides two areas of information: (1) the current value, or equity, of an entity and (2) any changes in value—profit or loss—taking place in the business from a given period.

Management officials, investors, and credit grantors all require this kind of information: management to interpret the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the upshots of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to assess the financial statements of an enterprise in judging whether to allow a loan.

Evidence of financial and numerical records have been seen for just about every state with a commercial backbone. Records of business contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates have been made in ancient Greece and Rome. The two-entry style of bookkeeping started with the furthering of the business republics of Italy, and tutorial manuals for bookkeeping were developed during the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial books a necessity. The history of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in part, helped forming it. The international revolution of industrial and commercial activity called for higher sophisticated decision-making processes, which in turn needed greater sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government regulation became more detailed and resulted in even greater requirement for information; entities had to provide information to bolster 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 operations became larger.

While bookkeeping procedures can be very detailed, all are based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger must have the details of individual accounts. The daily records in the journals are put in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted from the ledger. The duty of the income statement or profit-and-loss statement is to display an analysis of any changes that took place in the enterprise equity resulting due to the operations of the period. The balance sheet shows the financial condition of the company at any particular point with regard to assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.

Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.

Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.

But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).

During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.

North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields 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. Your jet fighter pilot experience is available in Melbourne, Cairns and Townsville. Visit flyingwarbirds.com.au for more details. For mini bus hire Brisbane, contact Group 1 Minibus.
