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, which stands for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most popular projector imaging technologies. With so many brands and different models available, it can be confusing for the buyer to choose between these technologies. It comes down to the fact that LCD projectors have superior image quality and colour accuracy. The next part of this article will explain why DLP projectors struggle with creating a comparable level of image quality.

Visualise a set of blinds in your house over your bedroom window. By pulling on a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. Such is exactly how an LCD projector operates. Each pixel operates like its own 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 the pros like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the picture reaches your screen is vitally significant to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by dividing it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to form the projector image. A point to understad about LCD projectors is that all three colours are sent onto your projected surface simultaneously. The way a DLP projector operates is totally different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of creating an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s vision 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 create the highest brightness and great colour accuracy. In DLP, just one colour is available at any given time, causing lower colour brightness and accuracy. Some developers have added a white segment for the colour wheel to improve overall brightness, but this also damages colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and therefore must be superior quality. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is capable of producing. DLP projectors do offer high contrast specifications when compared to the majority of LCD projectors. At first glance, this appears to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room where the projector is in use. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you are trying to bring to life requires moving images, DLP projection technology can also create image errors, or ‘artifacts’. The most typical artifact that a DLP projector forms with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change position between the time red, blue and green colours are projected. LCD projectors do not have this problem because all colours are processed with the others. DLP designers have developed 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them hardly practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Take yourself back to high school science, and remember how the different colours of light refract different amounts when passing through the same lens. The problem with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light at different levels. Often with a DLP projector, an extra yellow colour will come up above and a spill of blue will show below an image of something as simple as a straight black line. While being built LCD projectors can be adapted to remove these effects on the projected image, because each colour is directed on separate LCD panels.

The one true plus (excluding price) with deciding on a DLP projector is its smaller total size and weight. However, this is only relevant to transporting the device and has to be traded off against the image benefits of LCD projectors. If overall picture quality is vital to you, then the solution is a no-brainer. Go for an LCD projector! LCD projectors will consistently create bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the initial yacht was a leisure craft used initially by royalty and then by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private games. English yachting began with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting became fashionable with the affluent and nobility, but after that point the habit did not last.

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

Yacht racing was seen in some stipulated manner on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht society 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 perpetual setting of British racing. The club at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing matches for high stakes were held, and the social life was splendid. Eventually 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 had power. Sailing was largely for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a benchmark of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The style of large yachts was first largely affected by the win of America, which was created by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. Earlier yachts were not designed and built in a contemporary sense, with just a model being 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 use of the research of aerodynamics do for the design of sails and rigging what such study had already done for hulls.

Because almost all sailboats were individually manufactured, there was a desire for handicapping boats as this was before the one-design class boats were designed. Hence, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the most rapidly flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to single specifications in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even basis with no handicapping necessary. A prime example is the standard International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

As long as yachting belonged mostly for the nobility and the wealthy, cost was no object, and the size of boats increased, in both length and weight. The rise and preference of smaller boats came in the second 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 demonstrated the value of small boats. Later in the 20th century, notably after World War II, smaller racing and recreational craft became commonplace, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, at which point steam was set to replace sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly favoured in pleasure vessels. Bigger power yachts were progressed to a high degree, and long-distance cruising became a fond occupation of the affluent. The early 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 fashion for several years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were only power yachts with gasoline or diesel engines.

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

As larger and more dependable internal-combustion engines were created, many big yachts were using them for power. The development of the diesel engine, employing heavy oil for fuel, progressed during World War I. During the decade following that, bigger power-yacht building grew, hitting a climax in the Orion (1930) at 3,097 tons. During that period the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power yachts lessened from 1932, and the fashion from then was in preference of smaller, less pricey yachts. Following World War II, lots of small naval boats were traded by private owners for conversion to yachts. By the late 20th century, yachting had become a internationally loved competition enjoyed by thousands of yachtsmen who are actually manning and keeping their own small leisure yachts. The number of craft and sailors increased steadily, not only in the traditional places by the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the distribution of income and wealth. A proportional tax is one that impinges the same relative burden on every taxpayer—i.e., when tax liability and income move in equal scale. A progressive tax is recognisable by a higher than proportional rise in the tax onus in relation to the increase in income, and a regressive tax is recognisable by a less than proportional increase in the related liability. Therefore, progressive taxes are thought of as taking away a lack of equality in income distribution, whereas regressive taxes may have the effect of increasing these inequalities.

The taxes that are normally thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so for the upper-income demographic—especially if a taxpayer is allowed to lessen his tax base by declaring deductions or by removing certain income parts from his taxable income. Proportional tax rates that are applied to lower-income classes would also be more progressive if exemptions of a personal nature are made.

Income measured over the period of a given year may not necessarily provide the best measure of taxpaying requirements. For example, transitory increases in income can be saved, and within temporary declines in income a taxpayer could elect to finance consumption by decreasing savings. Therefore, if taxation is held in comparison with “permanent income,” it can be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (save those on luxuries) are mostly regressive, because the portion of individual income consumed or spent for a specific good decreases as the level of personal income rises. Poll taxes (aka head taxes), calculated as a flat amount per capita, patently are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being considered.

In analysing the economic effect of taxation, it is essential to differentiate between various ideas of tax rates. The statutory rates will be dictated in legislature; usually these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income increases by one dollar. Therefore, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation usually contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates are required to consider 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 greater than specified within the statutory rates. Since marginal rates display 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 understand the marginal effective tax rate to apply to income from business and capital, as it may depend on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is required in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly rise with income, both because personal allowances are provided for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received for the most part by high-income households might dwarf these effects, allowing regressivity, as displayed by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs built in projection systems are generally small reflective or transmissive panels illuminated by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image then displays it on a screen. With front-projection systems the LCD is situated on the same side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of more expense and capacity sometimes use three separated LCD panels, reflecting separate red, green, and blue images that come together to form a coloured display on the screen.

The growth in demand for pictographic presentations has granted a particular emphasis on the switching speed of liquid crystals. This has led to the creation of items employing smectic liquid crystals, particular types of which emit a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. Within it the liquid crystal molecules are set out in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are tilted, as displayed in the figure. The host liquid crystal holds optically active molecules, and a subtle outcome of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Thus, there exists a permanent charge separation through 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 corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark if one or more polarizers are used.

SSFLC devices have been commercialized for bigger passive-matrix presentations, but their high cost and complexity has stopped them from creating any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be used in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast pace (approx 100 cycles every second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods then to a nontransmissive state during the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture objects, the chair might be the imperative one. While most of the other pieces (apart from the bed) are created to support objects, the chair supports the human form. The term chair can be used here in the general sense, from stool to throne to derivative forms including a bench or sofa, which should be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently defined.

The social history of the chair is as exciting as its history as a creative craft. The chair is not merely a physical support and/or aesthetic object; it is also semiotic of social hierarchy. From the old royal courts there were significant distinctions between having a chair with arms, or a chair with a back but no arms, or having to make do with a stool. In the 20th century, the director’s or manager’s chair has risen iconic of superior rank, and in democratic government debate the speaker sits on a higher floor.

As its furniture construction, the chair is used for a number of different models. There are chairs designed to match man’s age and physical form (the high chair, the wheelchair) and to denote his standing in society (the executive chair, the throne). During historical days there were chairs for births (birth chairs); from the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, and/or 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 contemporary lifestyle has demanded particular chairs in automobiles and aircraft. Every one of these chair shapes has changed to suit to changing human uses. Due to its unique relationship with man, the chair lives to its full purpose only when used. While it doesn’t make any difference to one’s appreciation of a cupboard or a dresser drawers if there are items inside or not, a chair is seen best and fairly evaluated by a person utilising it, because chair and sitter require each other. Thus the various limbs of a chair have been given labels according to the names of the human parts: arms, legs, feet, back, and seat.

Because the primary work of the chair is to support a human body, its credit is tested basically by how fully it does measure up to this practical function. Within the structure of the chair, the carpenter is restricted in particular static regulations and principal measurements. Through these limits, however, the chair maker has large freedom.

The history of the chair extends over a period of several thousand years. There are societies that had made significant chair forms, expressions of the premier work in the industries of craft and creativity. Within such civilisations, individual mention must 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 masterful design, are today a finding from findings made in tombs. The first of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs formed as akin to those of some animal, a curved seat, and with a sloping back supported from vertical stretchers. From this a strong triangular construction was crafted. There appears to be no noteworthy differentiation in the structure of Egyptian thrones and chairs for typical peasantry. The main change exists in the intricacy of its ornamentation, in the selection of costly inlays. The Egyptian folding stool in all probability was crafted to be an easily packed seat for officers. As a camp stool this stool continued til much later periods. But the stool also took on the role of a ceremonial seat, its mechanical function as a folding stool fast forgotten. This can from today be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the form of folding stools but aren’t able to be folded as the seats are worked from wood. The easy build of the folding stool, composed of two frames that turn on metal bolts and have a seat of leather or fabric held between them, was seen again but somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of these is the folding stool, made from ashwood, found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is known not from any ancient specimen still around but seen in a wealth of pictorial objects. The most well known is the klismos drawn on the Hegeso Stele at the Dipylon burial area in outer Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were shown. These creative legs were thought to have been executed in bent wood and were as such had to bear a large amount of pressure from the weight of the sitter. The joints joining the legs to the frame of the seat had to be therefore extremely strong and were clearly drawn.

The Romans borrowed from the Greek design; designs of casts of seated Romans display evidence of a denser and in appearance kind of less delicately built klismos. Both kinds, the light and the heavy, were revived in the Classicist epoch. The klismos chair is known in French Empire styles, in English Regency, and in some brands of profound individuality in Denmark and Sweden around 1800.

China
The history of the chair in China cannot be charted as far back as the progression of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an undamaged serial of images and artworks had been kept safe, showing the interiors and outside of Chinese buildings and the kinds of furniture. Also preserved since the 16th century are a number of chairs made of wood or lacquered wood, that show an intriguing similarity to styles of ancient chairs.

Just like in Egypt, there existed two iconic chair designs in China: a chair that had four legs and a folding stool. That chair was constructed both with or without arms though always having the square seat and straight stiles (vertical side supports) to firm the back. In one image, though, the stiles were lightly curved by the arms to fit the structure of the S-shaped back splat (the main upright of a back). All three areas had been mortised in the yoke-like top rail. Despite that the innovation of a back splat then had an inspiration for English chairs of the Queen Anne period, wooden sections that merely to a particular capability reinforce corner joints (and were loose in the bargain) signify a design exclusive to Chinese chairs. The four legs are set through the seat frame, which ends upon the rounded staves. Every member is round in section or possesses rounded edges—acknowledging perchance to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited texture. These chairs required the sitter to stay stiff and upright; for when too much pressure is placed on the back, the chair has a tendency to fall. In patriarchal Chinese households of this period armchairs likely were allowed only for the senior individuals, for they were respected greatly.

The Chinese folding stool is believed to have taken to China from the West. It does not vary very much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is intricately held to the two legs of the stool by a curved member, which is more often than not seen with metal mounts. From a Western perspective the resultant effect of these two furniture items is stylized. The constructive and decorative elements are combined in a style that is all at once naïve and refined. The patched up appearance is a result of the way that the individual members do not look to have been held together by use of either glue or screws, but have been mortised on one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its mark on the chair. Artworks display a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to produce a pattern of little pads. The front board and a corresponding board in the back could be folded after loosening some small iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, at the same era, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be displayed in engravings of the inside of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not certain that the style actually was instigated in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was manufactured in large amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of such chairs lined up along a wall. The form asserts itself by its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, to say, as brought out in Paris around 1750—spread through most of Europe and was imitated or copied in the mid-20th century. The style owes its popularity to a combination of relaxation and delicacy. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of rather thick density; but each member is deeply molded, all superfluous wood has been cut away, and more upmarket chairs can be further embellished with very delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all upholstery on the seat, back, and armrests; canework is sometimes used as an alternative to upholstery.

English chairs in the 18th century were more differentiated in design than the French. The French touch for stylistic uniformity, which came from the highest circles in Paris and Versailles over most of France and was popular 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 commonly 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 charting of the money values of the operation of a business. Bookkeeping grants the information from which accounts are drafted but is a different process, prior to accounting.

Fundamentally, bookkeeping grants two parts of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking placement in the entity from a single period.

Management officials, investors, and credit grantors all demand this information: management in order to assess the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to analyse the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to regard the financial statements of an entity in finding whether to accept a loan.

Pieces of financial and numerical charts can be found for almost every state with a commercial backbone. Records of trading contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates were kept in ancient Greece and Rome. The dual-entry manner of bookkeeping began with the progression of the enterprising republics of Italy, and tutorials for bookkeeping were developed within the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial bookkeeping a necessity. The past of bookkeeping, in fact, reflects closely the ancestry of commerce, industry, and government and, in some part, assisted shaping it. The worldwide spread of industrial and commercial activity demanded higher cosmopolitan decision-making methodology, which in turn required greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislature became more detailed and resulted in greater need for information; enterprising firms had to provide information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the requirement for bookkeeping for their inner departmental operations went up.

Although bookkeeping procedures can be extremely detailed, all are based on two styles of books employed in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger has the record 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 created from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to give an analysis of the changes that have occurred in the entity equity resulting from the events of the period. The balance sheet displays the financial situation of the company at the particular point in time 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.
