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

The common question customers ask when looking for a new projector for the home, office, or classroom is: would I purchase an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many different brands and types available, it can be challenging for customers to decide between those technologies. The simple fact of the matter is that LCD projectors offer far superior image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with creating the same rate of image quality.

Think of a set of blinds in your house over your bedroom window. By pulling a rod you can make the shutters open or closed, according to if you want to let light in or not. And such is exactly how an LCD projector operates. Each pixel functions like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element functions 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 absolutely 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 transfer the coloured light to 3 separate LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then combined in a glass prism to form the projector image. An important point to know about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector runs is very different and even the way an image shows up is not the same. With DLP, white light from the lamp is projected through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting 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 form the image elements. The elements of the image are projected 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 the total image. In LCD projectors, all colours are available all the time to create the best brightness and great colour accuracy. In DLP, just one colour is available at a time, and so resulting in lower colour brightness and accuracy. Some DLP developers have placed a white segment for the colour wheel to improve all over brightness, but this also damages colour accuracy.

I read in forums all the time that DLP offers a higher contrast ratio and ergo must be better quality. For those who do not know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is capable of. DLP projectors do provide high contrast specifications compared to most LCD projectors. Initially, this can seem to be a plus, however, in real life, the true black level is determined by the ambient light in the room in which the projector is used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to bring to life includes moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most typical artifact that a DLP projector displays with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change between the time red, blue and green colours are projected. LCD projectors do not have this disadvantage because all colours are processed at the same time. DLP developers have created 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them almost impossible for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and recall when they taught you how different colours of light refract different amounts when directed through the same lens. The downfall 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 obviously not the same and refract light at different levels. Often with a DLP projector, an extra yellow colour will show above and a spill of blue will appear below an image as simple as a lone black line. In building LCD projectors can be fixed to minimize these effects on the projected image, because each colour is projected on a separate LCD panels.

The isolated real advantage (excluding price) with buying a DLP projector is its smaller size and weight. However, this is only relevant to transport and has to be traded off against the image benefits of LCD projectors. If resulting picture quality is vital to you, then the decision is easy. Go for an LCD projector! LCD projectors will constantly make bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht was a pleasure craft used first by royalty and secondly by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure 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), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting rose as classy among the affluent and royalty, but after that point the habit did not last.

The first yacht club in the British Isles, the Water Club, was instigated at 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 an imagined enemy. The club went on, for the large part as a social club, until 1765, and in 1828, after joining with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some stipulated fashion on the Thames about the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to monarchy in 1820, it was then called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British racing. The association at Cowes became the Royal Yachting Club, likewise at the rise of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the club life was wonderful. Ultimately 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 went on when the English held control. Sailing was mostly for leisure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first continuing American yacht club, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The design of sizeable yachts was first heavily impacted by the victory of America, which was designed by George Steers for a club headed 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 crafted in today’s sense, with just a model for an outline. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the design of sails and rigging what science had done earlier for hulls.

Because most of all sailboats were individually built, there arose a desire for handicapping boats previous to the one-design class boats were built. Hence, a rating rule was decreed, which is found in the International Rule, accepted in 1906 and amended in 1919. Today, one of the rapidly growing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are created to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for those boats can be had on an even basis with no handicapping necessary. A great example is the uniform International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

So long as yachting belonged primarily for the nobility and the wealthy, cost was no problem, and the size of boats developed, in both length and weight. The promotion and desire of smaller craft occurred 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 voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of smaller boats. Following this in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, when steam started to take the place of sail power in commercial craft, the steam engine, and later the internal-combustion engine, were used increasingly in personal vessels. Bigger power yachts were furthered to a high standard, and long-distance sailing turned into a fond activity of the well off. The first power yachts were paddle-wheel boats; they then made way to boats powered by the completely submerged screw or propeller type of propulsion. As in the case of naval and merchant craft, auxiliaries with both sail and power were the yacht archetype for several years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were only power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a push in the manufacture of bigger steam yachts. Conspicuous among 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, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As larger and more reliable internal-combustion engines were produced, many big craft began using them for power. The creation of the diesel engine, with heavy oil for fuel, advanced in World War I. From the decade after, large power-yacht building grew, reaching a climax in the Orion (1930) at 3,097 tons. During that point the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of big power craft declined in 1932, and the fashion from then was for smaller, less costly craft. Following World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting is a globally popular activity enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small pleasure yachts. The popularity of yachts and owners increased steadily, not only in the traditional locations on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the placement of income and wealth. A proportional tax is the kind that places the same relative liability on all taxpayers—i.e., where tax liability and income increase in equal levels. A progressive tax is recognised by a more than proportional rise in the tax onus relative to the increase in income, and a regressive tax is characterized by a less than proportional rise in the comparative burden. Therefore, progressive taxes are regarded as reducing inequity in income distribution, while regressive taxes can have the result of an increase in these inequalities.

The taxes that are generally regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so in the upper-income class—particularly if a taxpayer is permitted to lessen his tax base by claiming deductions or by leaving out some certain income aspects from his taxable income. Proportional tax rates when applied to lower-income categories will also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the period of a given year does not definitely give the most appropriate measure of taxpaying requirements. For example, transitory increases in income could be saved, and within temporary declines in income a taxpayer may opt to finance consumption by decreasing savings. So, if taxation is regarded along with “permanent income,” it should be less regressive (or more progressive) than when compared with annual income.

Sales taxes and excises (save on luxuries) are generally regressive, because the spread of one’s income consumed or spent for a specific good decreases as the level of personal income rises. Poll taxes (also known as head taxes), levied as a fixed amount per capita, obviously are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden depends for the most part on whether a national or a subnational (that is, provincial or state) tax is being determined.

In analysing the economic purpose of taxation, it is important to differentiate between various points of tax rates. The statutory rates are dictated in law; commonly these are marginal rates, but sometimes they are median rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income is increased by one dollar. Ergo, if tax onus increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates must review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than indicated in 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 nominate 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 holds that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates display the part of total income that is taken in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually increase with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households might swamp these effects, allowing regressivity, as signified by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs utilised for projection systems are generally small reflective or transmissive panels set off by a powerful arc lamp source. A line of lenses magnifies the reflected or transmitted image and then displays it on the screen. With front-projection systems the LCD is situated on the same area of the screen as the viewer, however in rear-projection systems the screen is set off from behind. Projectors of greater cost and performance can utilise three discrete LCD panels, forming separate red, green, and blue images that combine to create a coloured picture on the screen.

The growth in requirement for pictographic displays has put a special emphasis on the switching speed of liquid crystals. This has demanded the development of objects using smectic liquid crystals, particular kinds of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. Within it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and within the layers the molecules are slanted, as shown in the figure. The host liquid crystal has optically active molecules, and a subtle turn up 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 through the plane of the layers. Hence, there has to be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark when one or more polarizers are utilised.

SSFLC devices have been marketed for bigger passive-matrix displays, but their expense and complex detail has hindered them from making any great impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some possibility for use as aspects in projection systems or as viewfinders in digital cameras. Their quick response allows them to be used in time-sequential colour systems, in which expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid speed (approximately 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods and then to a nontransmissive state for 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 forms, the chair could be the most imperative. While most of the other objects (save for the bed) are designed to support objects, the chair supports your human form. The term chair can be viewed here in the wider sense, from stool to throne to complex pieces for example a bench or sofa, which can be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly definitive.

The social history of the chair is as curious as its history as a creative craft. The chair is not simply a physical support and an aesthetic piece of art; it historically is a signifier of social hierarchy. Within the Medieval royal courts there were significant connotations between being led to a chair with arms, on a chair with a back but without arms, and having to utilise a stool. From the past century, the director’s and manager’s chair has risen an identifier of superior dignity, and in democratic government debate the speaker sits on an elevated level.

In its furniture purpose, the chair can be used for a range of different models. There are chairs manufactured to fit man’s age and physical abilities (the high chair, the wheelchair) and for his position in society (the executive chair, the throne). In past times there were chairs to be born in (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated new chairs for automobiles and aircraft. All of these chair forms has been adapted to suit to changing human uses. For its significant association with man, the chair exists to its full advantage only when being used. Although it doesn’t make any difference to one’s appreciation of a cupboard or a bureau whether there might be items inside or not, a chair is understood and fairly tested with a person sitting in it, for chair and sitter need each other. Thus the several parts of the chair are labeled likened to the elements of a human shape: arms, legs, feet, back, and seat.

Because the elemental role of your chair is to support the human body, its credit is judged generally on how suitably it measures up to this practical purpose. In the construction of a chair, the designer is limited with particular static regulations and principal measurements. Through these regulations, however, the chair maker has large freedom.

The history of the chair extended over an era of several thousand years. There existed cultures that had significant chair shapes, as seen of the principal craft in the industries of skill and art. From those peoples, a 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of skilled craft, were known from tomb discoveries. The first of the two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have had four legs shaped akin to those of an animal, a curved seat, leading to a sloping back supported above vertical stretchers. In this design a durable triangular design was created. There was to all appearances no notable differentiation in the creation of Egyptian thrones and chairs for ordinary non-royals. The simple variation was in the intricacy of its ornamentation, in the choice of more expensive inlays. The Egyptian folding stool in all likelihood was manufactured to be an easily carried seat for army officers. As a camp stool this type stayed for much later periods. But the stool also then was designed for the task of a ceremonial seat, its original role as a folding stool being forgotten. This can now be noted, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are constructed in the structure of folding stools but cannot be folded because the seats were worked out of wood. The simplistic build of the folding stool, consisting of two frames that cycle on metal bolts and have a seat of leather or fabric set between them, then came up but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this form is the folding stool, made out of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not with any ancient item still existing but as found in a large amount of pictorial objects. The archetype is the klismos drawn on the Hegeso Stele at the Dipylon burial location by 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 displayed. These unique legs were probably created from bent wood and were likely to have been bore great pressure under the weight of the sitter. The joints joining the legs to the frame of the seat are therefore extremely solid and were clearly drawn.

The Romans adopted the Greek design; quite a few models of seated Romans are chairs of a denser and are a kind of less delicately built klismos. Both designs, light or heavy, were brought back within the Classicist time. The klismos style is known in French Empire styles, in English Regency, and in special forms of profound individuality of Denmark and Sweden from 1800.

China
The progression of the chair in China cannot be traced as long as the history of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed folio of images and artworks had been kept, showing the inside and outer parts of Chinese houses and the kinds of furniture. Another preservation of the 16th century are a number of chairs made from wood or lacquered wood, that bear an astonishing likeness to designs of ancient chairs.

As was the case in Egypt, there existed two iconic chair forms in China: a chair having four legs and a folding stool. This chair is seen both with and without arms though always having its square seat and straight stiles (upright side supports) to firm the back. In one form, though, the stiles could be slightly curved over the arms for the purpose of sit right with the shape of the S-shaped back splat (the main upright of a back). Together, all three sections had been mortised in the yoke-like top rail. While the design of this back splat exercised a foundation for English chairs during the Queen Anne period, wooden pieces that would only to a restricted extent embolden corner joints (as well as being loose additionally) are a design signatory to Chinese chairs. The four legs sit through the seat frame, which closes over the rounded staves. All the members are round in section or has rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is uncomfortable and might have had a plaited seat. These chairs required the sitter to stay stiff and upright; for if too much pressure is exerted on the back, the chair has a habit of collapsing. In patriarchal Chinese houses of this era armchairs probably were reserved for senior individuals, for they were held in great esteem.

The Chinese folding stool is presumed to have come to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is delicately held to the two legs of the stool by using a curved member, which is usually provided with metal mounts. From a Western understanding the resultant effect of both furniture items is stylized. The structure and decoration aspects are combined in a style that is both naïve and refined. The piecemeal appearance is an outcome of the way that the individual members do not seem to have been affixed by use of either glue or screws, but are mortised on one another and fixed in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Works of art show a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in the layers, stitched to bring up a pattern of small pads. The front board and a corresponding board at the back could be folded after unscrewing some tiny iron hooks. Therefore the chair was a portable piece of furniture when traveling which, at the same time, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is evidenced 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 design of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the design actually started in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in considerable amounts, as indicated from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up by a wall. The design asserts itself by virtue of its harmonious 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 developed in Paris around 1750—disseminated over most of Europe and was imitated or copied in the mid-20th century. The style owes its popularity to a combination of comfort and delicacy. The seat conforms to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike principles despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those are constructed from wood of quite thick density; but all the members are deeply molded, all extraneous wood has been removed, and more expensive items might be further embellished with special delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all the upholstery on the seat, back, and armrests; cane is sometimes used instead of upholstery.

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

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

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

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

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping provides the numbers from which accounts are prepared but is a previous process, prior to accounting.

Fundamentally, bookkeeping records two kinds of information: (1) the current value, or equity, of an entity and (2) any changes in value—profit or loss—taking position in the enterprise from a singular time.

Management officials, investors, and credit grantors all need to have this kind of information: management so as to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to assess the financial statements of an entity in assessing whether to grant a loan.

Traces of financial and numerical records are found for nearly every country with a commercial backbone. Records of commercial contracts were uncovered in the ruins of Babylon, and accounts for both farms and estates have been made in ancient Greece and Rome. The double-entry style of bookkeeping came up with the progression of the business republics of Italy, and instruction manuals for bookkeeping were produced during the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a necessity. The past of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, partially, assisted shaping it. The global expansion of industrial and commercial activity demanded greater professional decision-making procedures, which in its turn required more sophistication in the selection, classification, and presentation of information, even more so with the assistance of computers. Taxation and government regulation became more significant and resulted in increased requirement for information; entities 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 became sizeable, and the demand for bookkeeping for their inner operations became higher.

Though bookkeeping methodology can be extremely detailed, it is all based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and so on), and the ledger contains the details of individual accounts. The daily records from the journals are written in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are created from the trial balance posted out of the ledger. The job of the income statement or profit-and-loss statement is to display an analysis of any changes that happen in the entity equity due to the transactions of the period. The balance sheet provides the financial situation of the business at any particular date taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields produced 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.
