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

The most common question asked when acquiring a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and models available, it can be overwhelming for the buyer to choose between these technologies. The simple fact of the matter is that LCD projectors offer far better image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with reproducing the same standard of image quality.

It’s like a set of blinds in your household over your bedroom window. With the twist of a rod you can make the shutters open or closed, according to whether you want to let light in or not. This is exactly how an LCD projector behaves. Each pixel functions like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from when the projector turns on to when the content reaches your screen is absolutely important with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which send the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then projected in a glass prism to create the projector image. A significant point to understad about LCD projectors is that all three colours are projected onto your wall simultaneously. The way a DLP projector operates is widely different and even how an image comes out 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 making an image requires 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 projected in sequence on the screen, one colour at a time. The viewer’s vision will then pull together each coloured element of the image into the complete image. From LCD projectors, all colours are available all the time to deliver top brightness and spectacular colour accuracy. In DLP, just one colour is available at a time, resulting in lower colour brightness and accuracy. Some manufacturers have placed a white segment in the colour wheel to improve all over brightness, but this then damages colour accuracy.

I find in forums all the time that DLP provides a higher contrast ratio and thus must be superior 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 technology is capable of producing. DLP projectors do offer high contrast specifications compared to the majority of LCD projectors. At one glance, this seems to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room while the projector is utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to bring to life needs moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most common artifact that a DLP projector forms with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because the colours are projected at once. DLP builders have formed 3DLP solutions using 3 chips to solve the colour break up issue, but the price tag of these projectors make them impractical for the large part of businesses and consumers.

Another differentiation 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 how different colours of light refract varied amounts when shone through the same lens. The disadvantage with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Most of the time with a DLP projector, an extra yellow colour will show above and a spill of blue will be projected below an image as simple as a straight black line. While being built LCD projectors can be adjusted to reduce these effects on the projected image, as each colour is processed on a separate LCD panels.

The only true advantage (excluding price) with buying a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to portability and must be traded off against the image benefits of LCD projectors. If the outcome of the picture quality is crucial to you, then the answer is no-brainer. Go for an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht had been a leisure craft used first by royalty and secondly by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from 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 presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting became classy among the wealthy and nobility, but after that period the fashion did not last.

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

Yacht racing was first seen in some organized manner on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was then named 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 club had been initiated 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 setting of British yachting. The association at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the club life was wonderful. Eventually Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English had dominance. Sailing was for the most part for leisure and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a minimum 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 started in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of bigger yachts was initially greatly impacted by the win of America, which was created by George Steers for a association headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. The first yachts were not designed and crafted in a contemporary sense, with merely a model being 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 employment of the study of aerodynamics do for the design of sails and rigging what such science had done earlier for hulls.

Because nearly all sailboats had to be individually custom-built, there was a need for handicapping boats before the one-design class boats were built. Thus, a rating rule was created, which ended up in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the fastest flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to standard requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even par with no handicapping required. A great 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 belonged mostly for the aristocracy and the rich, cost was no problem, and the size of boats increased, in both length and weight. The ascendancy and popularity of smaller craft occurred 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 voyage 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 smaller craft. Following this in the 20th century, particularly after World War II, smaller racing and recreational yachts became commonplace, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, in which steam started to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in personal yachts. Sizeable power yachts were furthered to a high degree, and long-distance cruising turned into a favourite activity of the rich. The first power yachts were paddle-wheel boats; these then gave way to yachts powered by the completely submerged screw or propeller sort of propulsion. Like naval and merchant boats, auxiliaries carrying both sail and power were the yacht standard for several years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts that had gasoline or diesel engines.

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

As bigger and more dependable internal-combustion engines were produced, many bigger boats began using them for power. The development of the diesel engine, employing heavy oil for fuel, was furthered from World War I. During the decade following that, big power-yacht building grew, climaxing in the Orion (1930) at 3,097 tons. In that time the best auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power boats lessened from 1932, and the trend thereafter was for smaller, less pricey boats. Following World War II, lots of small naval vessels were traded by private owners for conversion to yachts. By the late 20th century, yachting has become a widespread loved activity enjoyed by thousands of yachtsmen who are actually manning and keeping their own small recreational craft. The amount of boats and yachtsmen increased 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 effect they have on the placement of income and wealth. A proportional tax is one that impinges the same relative liability on all the taxpayers—i.e., when tax liability and income grow in relative proportion. A progressive tax is characterizable by a more than proportional increase in the tax liability relative to the growth in income, and a regressive tax is characterizable by a less than proportional increase in the comparable onus. Therefore, progressive taxes are seen as taking away inequalities in income distribution, while regressive taxes may have the effect of an increase in these inequalities.

The taxes that are often believed to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, may become less so in the upper-income demographic—particularly if a taxpayer is allowed to lower his tax base by nominating deductions or by removing some income parts from his taxable income. Proportional tax rates if applied to lower-income categories would also be more progressive if personal exemptions are made.

Income measured over a given year does not definitely offer the most accurate measure of taxpaying requirements. For example, transitory increases in income might be saved, and within temporary declines in income a taxpayer might decide to finance consumption by decreasing savings. So, if taxation is held in comparison with “permanent income,” it can be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (save luxuries) are mostly regressive, because the share of own income consumed or spent on specific goods declines as the amount of personal income is raised. Poll taxes (also called head taxes), levied as a fixed amount per capita, clearly are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to a lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden rests fundamentally on whether a national or a subnational (that is, provincial or state) tax is being decided.

In regarding the economic purpose of taxation, it is important to differentiate between differing concepts of tax rates. The statutory rates are those dictated in the legislation; usually these are marginal rates, but in some cases they are average rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income is increased by one dollar. Ergo, if tax burden rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations usually contain graduated marginal rates—i.e., rates that grow as income rises. Heavy analysis of marginal tax rates must review provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated by the statutory rates. Since marginal rates specify how after-tax income moves in response to changes in before-tax income, they are the necessary ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate applicable to income from business and capital, because it may be reliant 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 show the part of total income that is taken in taxation. The pattern of average rates is the one that is important for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received for the most part by high-income households could dwarf these effects, forcing regressivity, as signified by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs used in projection systems are generally small reflective or transmissive panels lit up by a forceful arc lamp source. A series of lenses magnifies the reflected or transmitted image and casts it on the screen. With front-projection systems the LCD is located on the side of the screen as the viewer, but in rear-projection systems the screen is illuminated from behind. Projectors of higher cost and capability sometimes use three separate LCD panels, forming separate red, green, and blue images that mesh to make a coloured image on the screen.

The increase in desire for film presentations has placed a special emphasis on the switching speed of liquid crystals. This has led to the development of items using smectic liquid crystals, some of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. In it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a tilt, as shown in the figure. The host liquid crystal possesses optically active molecules, and a minor outcome of the optical activity and the slant of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous 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 is a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix displays, but their expense and complex nature has prevented them from making any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as parts in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be made use of in time-sequential colour systems, in which highly expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in fast succession (approximately 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods and then to a nontransmissive state in the blue period, creating the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture items, the chair may be paramount. While most other items (save the bed) are designed to support objects, the chair supports your human form. The term chair was regarded here in the largest sense, from stool to throne to complex items including a bench or sofa, which might be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously labeled.

The social history of the chair is as stimulating as its history as an art and craft. The chair is not just a physical support or an aesthetic piece; it historically was a symbol of social ranking. Within the historical royal courts there were clear differences between sitting on a chair with arms, on a chair with a back but no arms, and having to sit on a stool. Since the past century, a director’s and/or manager’s chair has risen a signifier of superior position, and even in democratic government debate the speaker sits on a higher floor.

In a furniture creation, the chair can be employed for a number of variations. There are chairs structured to suit man’s age and physical capabilities (the high chair, the wheelchair) and for his position in society (the executive chair, the throne). Since the olden days there were chairs to be born in (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). We have chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated special chairs for automobiles and aircraft. All of these chair types has evolved to fit to growing human requirements. Because of its significant importance with man, the chair lives to its full meaning only when being used. Whereas it does not make a difference to one’s appreciation of a cupboard or a chest of drawers whether there might be items inside or not, a chair is really seen and regarded best with a person utilising it, for chair and sitter complement one another. Thus the different limbs of a chair are named corresponding to the limbs of our human form: arms, legs, feet, back, and seat.

Because the simple role of the chair is to support the human body, its credit is evaluated generally by how suitably it measures up to this practical function. Within the creation of the chair, the designer is bound in certain static legislation and principal measurements. Through these rules, however, the chair designer has extensive freedom.

The history of the chair extends over a period of several thousand years. There are peoples that made individual chair shapes, expressive of the topmost work in the areas of technique and design. In these such cultures, particular note 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of skilled design, are today found from discoveries made in tombs. One of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs formed akin to those of some animal, a curved seat, leading to a sloping back supported over vertical stretchers. In this design a solid triangular design was obtained. There appears to be no marked change from the creation of Egyptian thrones and chairs for regular populace. The real variation lies in the kind of ornamentation, in the particulars of more valuable inlays. The Egyptian folding stool in all likelihood was designed as an easily stored seat for officers. As a camp stool the form stayed around til much later times. But the stool also then existed in the purpose of a ceremonial seat, its technical history as a folding stool simply forgotten. This can today be seen, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the construction of folding stools but aren’t able to be folded as the seats are created of wood. The simple structure of the folding stool, composed of two frames that turn on metal bolts and support a seat of leather or fabric held between them, came again somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this form is the folding stool, made of ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not with any ancient specimen still around but found in a wealth of pictorial objects. The archetype is the klismos seen on the Hegeso Stele at the Dipylon burial place near Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of those can be seen. These curving legs were most likely created of bent wood and were likely to have been needed to bear a large amount of pressure with the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore extremely strong and were visibly pointed out.

The Romans adopted the Greek design; evidence of models of seated Romans are evidence of a denser and in appearance rather more crudely built klismos. Both features, the light or the heavy, were popularised as part of the Classicist period. The klismos style can be evidenced in French Empire chairs, in English Regency, and in some special brands of notable originality around Denmark and Sweden during 1800.

China
The progression of the chair in China is not able to be followed as well as that of Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed series of sketches and paintings has been kept safe, displaying the insides and outer parts of Chinese houses and the designs of furniture. Also kept from the 16th century are some chairs made of wood or lacquered wood, that bear an intriguing similarity to representations of older chairs.

As were the designs in Egypt, there were two fundamental chair forms in China: a chair of four legs and a folding stool. This four-legged chair has been found both with and without arms but always with a square seat and straight stiles (straight side supports) to firm the back. In one style, it has been seen, the stiles are slightly curved by the arms for the purpose of fit the shape of the S-shaped back splat (the main upright of a back). All three areas were mortised onto the yoke-like top rail. Although the style of the back splat exercised an introduction for English chairs during the Queen Anne period, wooden items that would merely to a limited limit stabilise corner joints (and then are loose additionally) signify an element solely to Chinese chairs. The four legs pass through the seat frame, which closes upon the rounded staves. Each member is round in section or have rounded edges—a left over perchance to the bamboo tradition. The seat is not pleasant and had on occasion a plaited texture. These chairs required the sitter to stay stiff and upright; when too much weight is pushed on the back, the chair has a way of toppling. In patriarchal Chinese homes of this period armchairs probably were kept only for elderly persons, for they were given great respect.

The Chinese folding stool is understood to have come to China from the West. It is not dissimilar so very much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is intricately fixed to the two legs of the stool by a curved member, which is more often than not provided with metal mounts. From a Western point of view the overall effect of these two furniture items is stylized. The structure and decorative issues are combined in a way that is both naïve and refined. The patched up appearance is an upshot of the manner that the individual members do not look to have been constructed by means of either glue or screws, but had been mortised on one another and locked into its place in the manner of a Chinese puzzle.

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

The Netherlands: 17th century
A low, square, upholstered design of chair is found in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair might also be found in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not held that the form actually began in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was made in considerable numbers, as evidenced from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up against a wall. The style asserts itself by its harmonious proportions and delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, to say, as progressed in Paris around 1750—conquered most of Europe and has been imitated or copied during the mid-20th century. The design owes the popularity to a combination of comfort and charm. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike methods in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are constructed from wood of relatively thick density; but each member is deeply molded, all extra wood has been taken away, and finer designs may be further embellished with intricately delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used rather than upholstery.

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

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

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

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

Basically, bookkeeping records two types of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking placement in the business within a particular time period.

Management officials, investors, and credit grantors all have to have such information: management so as to interpret the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to understand the results 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 deciding whether to allow a loan.

Pieces of financial and numerical record charts can be found for just about every civilization with a commercial background. Records of business contracts have been discovered in the archaelogical digs of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The two-entry process of bookkeeping started with the progression of the business republics of Italy, and tutorial manuals for bookkeeping were developed during the 15th century in various Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a paramount factor. The ancestry of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in some part, assisted to form it. The worldwide revolution of industrial and commercial activity required higher professional decision-making processes, which itself called for more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislation became more important and resulted in greater demand for information; business firms had to show available information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the requirement for bookkeeping for their inner operations went up.

While bookkeeping methods can be extremely multifaceted, all are based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, etcetera), and the ledger contains the records of individual accounts. The daily records in the journals are written in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The duty of the income statement or profit-and-loss statement is to present an analysis of any changes that occurred in the enterprise equity as a result of the events of the period. The balance sheet displays the financial condition of the enterprise at any particular day derived 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 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 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.
