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

The most typical question customers ask when buying a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and models available, it can be challenging for consumers to pick between those technologies. The simple fact of the matter is that LCD projectors provide far better image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up a comparable level of image quality.

Imagine a set of blinds in your house over your bedroom window. By a 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 operates. Each pixel functions like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point at which the projector switches on to when the image reaches your screen is vitally important for 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 direct the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by turning each pixel on and off. The pixels are then projected in a glass prism to create the projector image. A point to know about LCD projectors is that all three colours are delivered onto your projected surface all at once. The way a DLP projector functions is widely different and even the way an image comes out is not the same. With DLP, white light from the lamp is projected through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image casts a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eyes will then draw each coloured element of the image into the complete image. With LCD projectors, all colours are available all the time to form high brightness and spectacular colour accuracy. In DLP, only one colour is available at once, causing lower colour brightness and accuracy. Some designers have added a white segment into the colour wheel to improve all over brightness, but this also detracts from colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and ergo 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 machine is capable of. DLP projectors do provide high contrast specifications compared to most LCD projectors. At first glance, this must be a benefit, however, in reality, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you wish to see requires moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change between the time red, blue and green colours are shone. LCD projectors do not have this problem because the colours are projected at the same time. DLP designers have developed 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price tag of these projectors make them almost impossible for many businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and remember how the various colours of light refract various amounts when passing through the same lens. The disadvantage with DLP projectors is that they use 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 in different ways. Often with a DLP projector, an extra yellow colour will come through above and some blue will come up below an image containing something as simple as a single black line. While being built LCD projectors can be adjusted to minimize these effects on the projected image, as each colour is processed on a separate LCD panels.

The sole veritable advantage (excluding price) with going with a DLP projector is its smaller size and weight. However, this is only relevant with regard to mobility and must be traded off against the image advantages of LCD projectors. If resulting picture quality is important to you, then the answer is simple. Choose an LCD projector! LCD projectors will always make 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 became a leisure craft used mostly by royalty and secondly by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting began 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 gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, 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 punt. Yachting rose as classy among the wealthy and aristocracy, but after that time the fashion did not last.

The first yacht club in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held much naval panoply and gravity. The closest thing to a race was the “chase,” in which the “fleet” pursued a fictional enemy. The club persisted, mostly as a social club, until 1765, and in 1828, by merging with other societies, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered manner on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came 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 formed 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 continuing setting of British yacht racing. The club at Cowes became the Royal Yachting Club, also at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing matches for high bids were held, and the society life was superlative. Eventually Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English took dominance. Sailing was for the most part for leisure and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and created a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The style of bigger yachts was originally largely put upon by the success of America, which was created by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. The first yachts were not designed and manufactured 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 study of aerodynamics do for the craft of sails and rigging what such study had already done for hulls.

Because almost all sailboats were individually custom-built, there arose a need for handicapping boats previous to the one-design class boats were made. Hence, a rating rule was created, which is found in the International Rule, accepted in 1906 and amended in 1919. Today, one of the most rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to the same dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be had on an even playing field with no handicapping at all. A perfect example is the standard International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

As long as yachting was an activity primarily for the nobility and the affluent, cost was no problem, and the size of boats developed, in both length and weight. The promotion and popularity of smaller craft occurred in the latter 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 journey around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of smaller craft. Later in the 20th century, particularly after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a favourite 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, in which steam was set to take the place of sail power in market vessels, the steam engine, and later the internal-combustion engine, were employed more and more in personal yachts. Bigger power yachts were developed to a high standard, and long-distance cruising was a preferred pastime of the wealthy. The earliest power yachts were paddle-wheel boats; these then gave rise to those powered by the fully submerged screw or propeller type of propulsion. As in the case of naval and merchant vessels, auxiliaries possessing both sail and power were the yacht standard for many years. By the later half of the 20th century, several yachts were still auxiliaries, but the larger part were solely power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the construction of bigger steam yachts. Notably of these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of more than 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service for World War II.

As larger and more dependable internal-combustion engines were created, many bigger craft began using them for power. The development of the diesel engine, using heavy oil for fuel, progressed for World War I. From the decade after that, bigger power-yacht manufacture flourished, climaxing in the Orion (1930) at 3,097 tons. During that time the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power craft lessened after 1932, and the style after that was toward smaller, less costly craft. From World War II, lots of small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting is a globally beloved activity enjoyed by thousands of yachtsmen individually owning and maintaining their own small recreational yachts. The popularity of yachts and owners increased steadily, not only in the traditional places on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the impact they have on the allocation of income and wealth. A proportional tax is a kind that applies the same relative burden on every taxpayer—i.e., in the case where tax liability and income increase in equal scale. A progressive tax is recognisable by a more than proportional growth in the tax onus relative to the rise in income, and a regressive tax is characterized by a less than proportional increase in the relative burden. Ergo, progressive taxes are regarded as removing the lack of equality in income distribution, but regressive taxes might have the result of increasing these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so in the upper-income demographic—particularly if a taxpayer is allowed to lower his tax base by declaring deductions or by taking some particular income elements from his taxable income. Proportional tax rates if applied to lower-income categories would also be more progressive if such personal exemptions are made.

Income measured over the course of a given year may not absolutely come up with the most suitable measure of taxpaying ability. For example, transitory increases in income may be saved, and in temporary declines in income a taxpayer might select to pay for consumption by reducing savings. Therefore, if taxation is held in comparison alongside “permanent income,” it can be less regressive (or more progressive) than when it is made comparable with annual income.

Sales taxes and excises (save on luxuries) are generally regressive, because the share of one’s income consumed or spent for specific goods lessens as the level of personal income grows. Poll taxes (also called head taxes), calculated as a standard amount per capita, patently are regressive.

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

In regarding the economic purpose of taxation, it is important to differentiate between various points of tax rates. The statutory rates include those dictated in the legislation; generally these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income grows by one dollar. Hence, if tax burden rises by 45 cents when income grows 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 increases. Heavy 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) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than indicated in the statutory rates. Since marginal rates specify how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for assessing incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applicable to income from business and capital, since 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 holds that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the portion of total income that is demanded in taxation. The pattern of average rates is the one that is important for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate rises 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 fundamentally by high-income households can dwarf these effects, allowing regressivity, as indicated by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs put for projection systems are typically small reflective or transmissive panels lit by a powerful arc lamp source. A series of lenses expands the reflected or transmitted image and displays it onto the screen. In front-projection systems the LCD is situated on the side of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of more expense and performance may use three separated LCD panels, reflecting separate red, green, and blue images that blend to form a coloured display on the screen.

The growing requirement for visual displays has had a growth in emphasis on the switching speed of liquid crystals. This has demanded the invention of objects using smectic liquid crystals, certain kinds of which give a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most sophisticated smectic device. Within it the liquid crystal molecules are set out 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 slant, as shown in the figure. The host liquid crystal contains optically active molecules, and a slight 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. So, there is a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly partnered 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 hence reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been marketed for larger passive-matrix presentations, but their expensiveness and complex detail has prevented them from enjoying any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick response allows them to be made use of in time-sequential colour systems, in which high cost colour filters are replaced by a coloured backlight that flashes red, green, and blue in fast pulsing (around 100 cycles a second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods but to a nontransmissive state in the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture objects, the chair may be of most importance. While many other items (save the bed) are meant to support objects, the chair supports a human form. The term chair is intended to be said here in the most common sense, from stool to throne to derivative forms including the 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 curious as its history as a creative art. The chair is not merely a physical support and/or an aesthetic artwork; it was historically semiotic of social status. From the past royal courts there were plain signifiers between being led to a chair with arms, sitting on a chair with a back but without arms, or worse having to use a stool. In the 20th century, the director’s or manager’s chair has risen a signifier of superior position, and in democratic parliaments the speaker sits on a higher floor.

As a furniture purpose, the chair encompasses a wealth of various purposes. There are chairs structured to fit man’s age and physical abilities (the high chair, the wheelchair) and to denote his status in society (the executive chair, the throne). From historical days there were chairs used for birth (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We design chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated special chairs for use in automobiles and aircraft. All of these chair shapes have been adapted to fit to differing human needs. From its significant relationship with man, the chair lives to its full importance only when in employ. While it makes no difference to one’s appreciation of a cupboard or a dresser drawers whether there might be items inside or not, a chair is seen best and fairly regarded by a person using it, because chair and sitter need each other. Thus the individual areas of a chair have been given names as the parts of our human shape: arms, legs, feet, back, and seat.

Because the original job of a chair is to support our body, its credit is tested basically for how suitably it does measure up to this practical function. Within the construction of a chair, the builder is limited under particular static rules and principal measurements. Under these limitations, however, the chair designer has extensive freedom.

The history of the chair lasts over a period of several thousand years. There were societies that had made unique chair forms, expressions of the leading task in the spheres of craft and aesthetics. From these such cultures, particular mention can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of careful design, are now seen from tomb findings. First of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs structured like those of a particular animal, a curved seat, leading to a sloping back supported over vertical stretchers. In this way a stable triangular construction was created. There was to our knowledge no significant change in the structure of Egyptian thrones and chairs for typical peasantry. The simple difference was in the level of ornamentation, in the evidence of more valuable inlays. The Egyptian folding stool most likely was created to be an easily carried seat for soldiers. As a camp stool that chair persevered during much later times. But the stool also took on the use of a ceremonial seat, its technical history as a folding stool being forgotten. This can from today be observed, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are constructed in the shape of folding stools but aren’t able to be folded as the seats were worked from wood. The simplistic construction of the folding stool, being of two frames that rotate on metal bolts and bear a seat of leather or fabric fastened between them, was seen again but somewhat later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of these is the folding stool, crafted out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not from any ancient object still extant but as seen in a wealth of pictorial items. The most well known is the klismos drawn on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those would be seen. These curving legs were considered to be manufactured with bent wood and were as such had to bear great pressure under the weight of the sitter. The joints joining the legs to the frame of the seat were therefore super solid and were plainly pointed out.

The Romans adopted the Greek style; designs of statues of seated Romans are examples of a denser and apparently slightly less delicately constructed klismos. Both designs, the light or heavy, were seen again during the Classicist time. The klismos chair can be seen in French Empire design, in English Regency, and in some special kinds of considerable individuality of Denmark and Sweden during 1800.

China
The ancestry of the chair in China cannot be tracked as far as in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed serial of drawings and artworks had been preserved, detailing the inside and exterior of Chinese houses and the designs of furniture. Another preservation of the 16th century are some chairs of wood or lacquered wood, that bear an amazing likeness to styles of past chairs.

Same as in Egypt, two particular chair forms existed in China: a chair of four legs and a folding stool. That four-legged chair can be seen both with and without arms though never without a square seat and straight stiles (standing side supports) to give support to the back. In one image, it has been found, the stiles are slightly curved above the arms in order to fit the form of the S-shaped back splat (the main upright of a back). The three areas had been mortised into the yoke-like top rail. While the innovation of this back splat later had an inspiration for English chairs in the Queen Anne period, wooden items that only to a particular extent stabilise corner joints (and then were loose as well) signify a design particular to Chinese chairs. The four legs pass through the seat frame, which closes about the rounded staves. All members are round in section or possesses rounded edges—referable perchance to the bamboo tradition. The seat is not pleasant and may have had a plaited seat. These chairs required of the sitter to stay stiff and upright; if too much weight is exerted on the back, the chair has a tendency to fall. In patriarchal Chinese houses of this era armchairs likely were kept for the senior persons in the family, for they were given great respect.

The Chinese folding stool is believed to have taken to China from the West. It does not differ that much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is intricately joined to the two legs of the stool with a curved member, which is usually seen with metal mounts. From a Western point of view the overall effect of both these furniture styles is stylized. The structure and aesthetic issues are combined in a manner that is all at once naïve and refined. The piecemeal appearance is an outcome of the way that the individual items do not seem to have been affixed by use of either glue or screws, but are mortised on one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its signature on the chair. Paintings project a design of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between, stitched to bring out a pattern of tiny pads. The front board and a related board in the back could be folded after loosening some tiny iron hooks. Therefore the chair was a readily portable piece of furniture in traveling which, during the same time, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be found in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair can also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the form actually started in The Netherlands. Generally, the legs of the chair will be smooth, round in section, and of slim dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in large quantities, as surmisable from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up against a wall. The style asserts itself by its shapely proportions and delicate upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, as created in Paris around 1750—disseminated through most of Europe and was imitated or copied during the mid-20th century. The model owes such popularity to a combination of comfort and charm. The seat adheres to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of fairly thick dimensions; but each member is deeply molded, all superfluous wood has been taken away, and more expensive examples may be further embellished with intricately delicate and decorative engraving. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all the upholstery on the seat, back, and armrests; cane is occasionally used in place of upholstery.

English chairs from the 18th century were more open in form than the French. The French preference for stylistic uniformity, which disseminated from the highest circles in Paris and Versailles through most of France and was popular 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 commonly known and was widely distributed throughout the world.

Late 18th to 20th century
In 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, suggest that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping grants the details from which accounts are drafted but is a separate process, preliminary to accounting.

Predominantly, bookkeeping provides two areas of information: (1) the current value, or equity, of an entity and (2) changes in value—profit or loss—taking place in the enterprise during a single time period.

Management officials, investors, and credit grantors all need this kind of information: management so as to understand the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to assess the outcomes of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to analyze the financial statements of a business in assessing whether to accept a loan.

Traces of financial and numerical recordkeeping have been found for nearly every state with a commercial history. Records of trading contracts were found in the archaelogical digs of Babylon, and accounts for both farms and estates were made in ancient Greece and Rome. The dual-entry style of bookkeeping came up with the progression of the entrepeneurial republics of Italy, and tutorial manuals for bookkeeping were created within the 15th century in various Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a paramount factor. The history of bookkeeping, in fact, resembles closely the history of commerce, industry, and government and, partially, assisted to shape it. The worldwide expansion of industrial and commercial activity required better sophisticated decision-making procedures, which in turn required greater sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government legislation became more detailed and resulted in even greater demand for information; entities had to show available information to bolster 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 demand for bookkeeping for their own inner departmental operations went up.

Although bookkeeping procedures can be very complex, all of it is based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger should have the information of individual accounts. The daily records from the journals are put in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to show an analysis of those changes that happen in the entity equity due to the transactions of the period. The balance sheet provides the financial position of the company at the 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 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.
