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

The most typical question asked when purchasing a new projector for the home, office, or classroom is: should I take an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many brands and different models available, it can be overwhelming for customers to make a choice between those technologies. It comes down to the fact that LCD projectors give superior image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with reproducing a comparable grade of image quality.

Imagine a set of blinds in your room on your bedroom window. With the twist of a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. And this is exactly how an LCD projector behaves. Each pixel functions like its own shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the picture reaches your screen is ultimately important to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which send the coloured light to 3 individual LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to deliver the projector image. Something to understad about LCD projectors is that all three colours are sent onto your projected surface all at once. The way a DLP projector works 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 directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are sent 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 a single full image. In LCD projectors, all colours are available all the time to form high brightness and superb colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment in the colour wheel to improve overall brightness, but this further detracts from colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and therefore must be better quality. For those who don’t know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of producing. DLP projectors do offer high contrast specifications compared to the majority of LCD projectors. Initially, this must be a benefit, however, in reality, the true black level is determined by the ambient light in the room in which the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to project needs moving images, DLP projection technology also creates image imperfections, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change position between the time red, blue and green colours are displayed. LCD projectors do not have this downside because all the colours are delivered simultaneously. DLP builders have come up with 3DLP solutions using 3 chips to answer the colour break up artifacts, but the expense of these projectors make them hardly practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and recall when they taught you how the various colours of light refract different amounts when directed through the same lens. The downfall 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 different and refract light in a different way. Usually with a DLP projector, a spill of yellow colour will show above and some extra blue will come through below an image of something as simple as a single black line. While being built LCD projectors can be adapted to reduce these effects on the projected image, as each colour is refracted on isolated LCD panels.

The only veritable benefit (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant for portability and has to be traded off against the image benefits of LCD projectors. If resulting picture quality is crucial to you, then the decision is easy. Go for an LCD projector! LCD projectors will always produce bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the initial yacht had been a pleasure 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 was incidental, arising as private challenges. English yachting began with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy 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, reigned 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting became classy among the affluent and aristocracy, but after that point the fashion did not last.

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

Yacht racing was first seen in some ordered 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 came to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, 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 sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing location of British yachting. The association at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for large bids were held, and the society life was lovely. Ultimately Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English had power. Sailing was largely for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens instigated the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first 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 craft of bigger yachts was originally heavily put upon by the victory of America, which was designed by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with just a model being used. Not until the second half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what such science had earlier done for hulls.

Because almost all sailboats had to be individually manufactured, there was a desire for handicapping boats as this was before the one-design class boats were designed. Therefore, a rating rule was written, which ended up in the International Rule, adopted in 1906 and revised in 1919. In modern times, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same specifications 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 required. A perfect example is the generic International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the royal and the wealthy, expense was no issue, and the size of boats increased, in both length and weight. The ascendancy and preference of smaller craft came in the second half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of less sizeable boats. Thereafter in the 20th century, for the larger part after World War II, smaller racing and recreational boats became more popular, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam started to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure vessels. Large power yachts were furthered to a high degree, and long-distance sailing became a preferred activity of the rich. The earliest power yachts were paddle-wheel boats; these then made way to those powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant craft, auxiliaries with both sail and power were the yacht standard for several years. By the later half of the 20th century, many yachts were still auxiliaries, but the majority were exclusively power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a push in the construction of bigger steam yachts. In particular within 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, purchased 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 developed, many big craft were using them for power. The establishment of the diesel engine, using heavy oil for fuel, progressed from World War I. From the decade after, bigger power-yacht building grew, climaxing in the Orion (1930) at 3,097 tons. In that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of large power craft fell away from 1932, and the trend from then was for smaller, less pricey yachts. Following World War II, lots of small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a globally loved activity enjoyed by thousands of yachtsmen personally owning and upkeeping their own small recreational craft. The number of yachts and yachtsmen increased steadily, not only in the traditional places by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the placement of income and wealth. A proportional tax is a kind that applies the same relative onus on every taxpayer—i.e., when tax liability and income grow in equal scale. A progressive tax is recognisable by a greater than proportional growth in the tax onus in relation to the increase in income, and a regressive tax is characterized by a less than proportional rise in the related onus. Thus, progressive taxes are thought of as fighting inequalities in income distribution, but regressive taxes might result in increasing these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so for the upper-income group—in particular if a taxpayer is permitted to lower his tax base by declaring deductions or by excluding some income components from his taxable income. Proportional tax rates that are applied to lower-income demographics would also be more progressive if such exemptions of a personal nature are claimed.

Income measured over a given period may not definitely provide the most accurate measure of taxpaying requirement. For example, transitory growth in income could be saved, and in temporary declines in income a taxpayer might select to provide for consumption by taking from savings. Thus, if taxation is regarded along with “permanent income,” it should be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (with the exception of luxuries) tend to be regressive, because the portion of personal income consumed or spent on specific goods lessens as the amount of personal income is raised. Poll taxes (aka head taxes), levied as a set amount per capita, patently are regressive.

It is not simple to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In analysing the economic effect of taxation, it is necessary to differentiate between various concepts of tax rates. The statutory rates will be dictated in legislature; generally these are marginal rates, but in some cases they are median rates. Marginal income tax rates denote the fraction of incremental income that is taken by taxation when income rises by one dollar. So, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature commonly contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates are required to take into account provisions in addition to 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 specified in the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the appropriate ones for considering incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate applied to income from business and capital, because it may be dependant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates determine the part of total income that is demanded in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received predominantly by high-income households could dampen these effects, producing regressivity, as indicated by average tax rates that fall as income increases.

The Development of Data Projectors

The LCDs utilised for projection systems are typically small reflective or transmissive panels set off by a bright arc lamp source. A number of lenses magnifies the reflected or transmitted image then casts it onto the screen. For front-projection systems the LCD is located on the same area of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of higher expense and performance may utilise three separate LCD panels, casting separate red, green, and blue images that combine to make a coloured display on the screen.

The growing requirement for pictographic presentations has placed a growth in emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices utilizing smectic liquid crystals, certain kinds of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most complex smectic device. In it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and throughout the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal has optically active molecules, and a minor consequence of the optical activity and the tilt of the molecules is the appearance 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 in the plane of the layers. So, there has to be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark if one or more polarizers are used.

SSFLC devices have been publicized for big passive-matrix displays, but their cost and complexity has prevented them from making any particular effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as parts in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be used in time-sequential colour systems, in which costly colour filters are removed for a coloured backlight that flashes red, green, and blue in quick succession (approximately 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods but then to a nontransmissive state for the blue period, having the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture objects, the chair may be the most important. While most of the other pieces (save for the bed) are meant to support objects, the chair supports a human form. The term chair must be used here in the wider sense, from stool to throne to further forms like a bench or sofa, which may be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinguished.

The social history of the chair is as stimulating as its history as a creative art. The chair is not merely a physical support or aesthetic craft; it historically is a symbol of social standing. From the old royal courts there were social connotations between being led to a chair with arms, on a chair with a back but no arms, or having to squat on a stool. During the recent century, a director’s and manager’s chair has become iconic of superior dignity, and in democratic government meeting the speaker sits on a higher platform.

In its furniture purpose, the chair can be used for a wealth of different makes. There are chairs manufactured to suit man’s age and physical form (the high chair, the wheelchair) and for his position in society (the executive chair, the throne). During past 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 make chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated particular chairs for automobiles and aircraft. Each and every one of these chair types have been adapted to match to changing human desires. Because of its unique connection with man, the chair comes to its full advantage only when utilised. Though it doesn’t make any difference to one’s appreciation of a cupboard or a dresser drawers if there might be anything inside or not, a chair is seen best and clearly evaluated with a person utilising it, for chair and sitter suit each other. Thus the several elements of the chair are labeled as the areas of our human body: arms, legs, feet, back, and seat.

Because the clear job of your chair is to support your body, its value is valued firstly from how fully it measures up to this practical function. Within the creation of a chair, the carpenter is bound in the static law and principal measurements. Under these regulations, however, the chair creator has marvellous freedom.

The history of the chair was an era of several thousand years. There are societies that held individual chair shapes, as expressions of the highest object in the industries of handling and design. Within these such civilisations, a 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of masterful scheme, are now seen from findings made in tombs. First of the two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair has four legs shaped like those of a particular animal, a curved seat, and leading to a sloping back supported with vertical stretchers. In this design a durable triangular structure was obtained. There appears to be no noteworthy differentiation from the construction of Egyptian thrones and chairs for regular citizens. The simple difference was in the intricacy of its ornamentation, in the choice of costly inlays. The Egyptian folding stool most likely was crafted as an easily stored seat for army soldiers. As a camp stool this form existed until much later times. But the stool then also was made as the task of a ceremonial seat, its technical task as a folding stool ignored or forgotten. This can from today be observed, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the structure of folding stools but cannot be folded as the seats were created of wood. The simplistic construction of the folding stool, composed of two frames that rotate on metal bolts and have a seat of leather or fabric secured between them, was then seen but some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of this form is the folding stool, made out of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not in any ancient fossil still in form but as seen in a trove of pictorial items. The iconic kind is the klismos displayed on the Hegeso Stele at the Dipylon burial ground by Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of which were shown. These strange legs were likely to have been crafted out of bent wood and were likely to have been had great pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat are therefore super stable and were clearly drawn.

The Romans adopted the Greek style; a number of casts of seated Romans display chairs of a heavier and apparently kind of less intricately constructed klismos. Both styles, light and heavy, were revived within the Classicist time. The klismos influence is known in French Empire furniture, in English Regency, and in some forms of notable originality in Denmark and Sweden circa 1800.

China
The ancestry of the chair in China can not be traced as far as in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed series of sketches and artworks was kept, detailing the interiors and exterior of Chinese buildings and the furniture. Also preserved of the 16th century are some chairs constructed from wood or lacquered wood, that display an intriguing likeness to designs of previous chairs.

As in Egypt, there was two major chair designs in China: a chair having four legs and a folding stool. This four-legged chair was designed both with and without arms however always having its square seat and straight stiles (vertical side supports) to firm the back. In one image, however, the stiles are lightly curved above the arms to suit the form of the S-shaped back splat (the central upright of the back). All three areas are mortised on the yoke-like top rail. Although the design of a back splat had an introduction for English chairs of the Queen Anne period, wooden sections that only just to a limited extent embolden corner joints (and then are loose as well) are a design signatory to Chinese chairs. The four legs sit through the seat frame, which stops about the rounded staves. Each member is round in section or is given rounded edges—a left over perhaps to the bamboo tradition. The seat is unpleasant to sit in and may have a plaited form. These chairs required of the sitter to stay stiff and upright; for when too much pressure is pushed on the back, the chair has a habit of falling over. In patriarchal Chinese houses of this epoch armchairs probably were only for senior individuals, for they were held in great respect.

The Chinese folding stool is understood to have travelled to China from the West. It is not dissimilar so very much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is prettily affixed to the two legs of the stool with a curved member, which is more often than not designed with metal mounts. From a Western understanding the resulting effect of both of these furniture styles is stylized. The structure and decoration issues are combined in a way that is simultaneously naïve and refined. The patched up appearance is a result of the manner that the individual members do not look to have been fixed with either glue or screws, but are mortised into one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its signature on the chair. Paintings display a style of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between, stitched to show up a pattern of little pads. The front board and a related board from the back could be folded after loosening some tiny iron hooks. In this way the chair was a portable piece of furniture while traveling which, at the same era, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is displayed in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the style actually was instigated in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of slim shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in considerable quantities, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of such chairs lined up against a wall. The design 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 created in Paris around 1750—disseminated over most of Europe and has been imitated or copied into the mid-20th century. The design owes such popularity to a combination of relaxation and charm. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are constructed strongly on craftsmanlike methods even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those employ wood of relatively thick density; but every member is deeply molded, all superfluous wood has been cut away, and more upmarket chairs would be further embellished with special delicate and decorative woodwork. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; cane is occasionally used instead of upholstery.

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

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

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

In cheaper 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, hint 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 transactions of a business. Bookkeeping provides the information from which accounts are written but is a separate process, prior to accounting.

Basically, bookkeeping provides two areas of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking position in the entity over a particular period.

Management officials, investors, and credit grantors all demand this kind of information: management in order to interpret the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors to analyze the financial statements of an entity in assessing whether to allow a loan.

Pieces of financial and numerical charts are seen for nearly every state with a commercial history. Records of trading contracts have been uncovered in the remains of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The double-entry way of bookkeeping began with the progression of the business republics of Italy, and instruction manuals for bookkeeping were developed during 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 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, in part, helped in forming it. The worldwide revolution of industrial and commercial activity needed more sophisticate decision-making procedures, which then needed greater sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government legislature became more important and resulted in higher requirement for information; business entities had to show available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the requirement for bookkeeping for their own inner operations became higher.

Although bookkeeping processes can be rather multifaceted, all are based on two styles of books used in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger contains the information of individual accounts. The daily records in the journals are put in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The duty of the income statement or profit-and-loss statement is to provide an analysis of any changes that occurred in the entity equity resulting due to the operations of the period. The balance sheet gives the financial situation of the entity 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 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.
