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

The common question heard when purchasing 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, an acronym for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many different brands and different types available, it can be confusing for consumers to decide between the two technologies. The fact is that LCD projectors provide better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with bringing up the same grade of image quality.

Think of a set of blinds in your household for your bedroom window. By a twist of a rod you can turn the shutters open or closed, according to if you want to let light in or not. Such is exactly how an LCD projector works. Each pixel works like its own shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as 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 is turned on to when the picture reaches your screen is ultimately significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by shining each pixel on and off. The pixels are then combined in a glass prism to deliver the projector image. A point to realise about LCD projectors is that all three colours are projected onto your projector screen simultaneously. The way a DLP projector operates is vastly different and even the way an image shows up is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image creates a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into a single total image. From LCD projectors, all colours are available all the time to offer high brightness and great colour accuracy. In DLP, just one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP designers have added a white segment for the colour wheel to improve brightness generally, but this then lessens colour accuracy.

I read in forums all the time that DLP offers a higher contrast ratio and thus must be superior quality. For those who are unaware, 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. DLP projectors do possess high contrast specifications as compared to many LCD projectors. At one glance, this can seem to be an advantage, however, in real life, the true black level is determined by the ambient light in the room in which the projector is in use. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to project has moving images, DLP projection technology can also create image errors, or ‘artifacts’. The most commonplace artifact that a DLP projector forms 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 displayed. LCD projectors do not have this downside because every colour is processed simultaneously. DLP builders have formed 3DLP solutions using 3 chips to answer the colour break up issue, but the expense of these projectors make them impractical for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they balance for the refractive qualities of light. Jump back to high school science, and they taught you how various colours of light refract various amounts when projected through the same lens. The disadvantage with DLP projectors is that they have the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in different ways. Often with a DLP projector, some extra yellow colour will show above and some blue will appear below an image containing something as simple as a single black line. In building LCD projectors can be adjusted to remove these effects on the projected image, as each colour is directed on its own LCD panels.

The sole actual advantage (excluding price) with going with a DLP projector is its smaller size and weight. However, this is only relevant in regard to mobility and cannot be traded off against the image plusses of LCD projectors. If overall picture quality is vital to you, then the solution is no-brainer. Choose an LCD projector! LCD projectors will consistently 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 first yacht became a pleasure 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 challenges. English yachting began with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting became fashionable for the rich and aristocracy, but after that period 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 organization, and held much naval panoply and gravity. The closest thing to racing was the “chase,” for which the “fleet” pursued an imagined enemy. The club went on, mostly as a social club, until 1765, and in 1828, after merging with other organisations, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized manner on the Thames in the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it came to be 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 organisation had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British yacht racing. The club at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the social life was splendid. Ultimately Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English took power. Sailing was largely for leisure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and created a minimum of luxury and elegance for the later yachts in those waters from the late 19th century. The first persisting American yacht association, 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
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of bigger yachts was originally largely impacted by the success of America, which was designed by George Steers for a club led 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 built in a contemporary sense, with merely a model being used. Not until the second half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the employment of the study of aerodynamics do for the design of sails and rigging what such study had previously done for hulls.

Because almost all sailboats had to be individually manufactured, there was a need for handicapping boats as this was previous to the one-design class boats were built. Thus, a rating rule was written, which is found in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the fastest flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to single dimensions in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing for those boats can be done on an even basis with no handicapping necessary. A great example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

As long as yachting was done mostly for the nobility and the wealthy, money was no issue, and the size of boats increased, in both length and weight. The promotion and popularity of smaller yachts occurred in the latter half of the 19th century from 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 demonstrated the hardiness of less sizeable yachts. 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 favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, during which steam began to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were employed increasingly in leisure yachts. Sizeable power yachts were furthered to a high element, and long-distance sailing was a favoured activity of the rich. The earliest power yachts were paddle-wheel boats; these then made way to yachts powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant craft, auxiliaries possessing both sail and power were the yacht fashion for a number of years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were only power yachts containing gasoline or diesel engines.

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

As larger and better quality internal-combustion engines were developed, many bigger boats started using them for power. The establishment of the diesel engine, with heavy oil for fuel, advanced from World War I. During the decade that followed, large power-yacht manufacture blossomed, climaxing in the Orion (1930) at 3,097 tons. During that period the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power boats fell away from 1932, and the fashion thereafter was in preference of smaller, less pricey boats. Following World War II, lots of small naval craft were traded by private owners for conversion to yachts. By the late 20th century, yachting had become a widespread popular competition enjoyed by thousands of yachtsmen individually owning and upkeeping their own small pleasure boats. The popularity of boats and owners increased steadily, not only in the traditional locations along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the distribution of income and wealth. A proportional tax is one that impinges the same relative requirement on all the taxpayers—i.e., in the case where tax liability and income move in equal levels. A progressive tax is recognisable by a more than proportional rise in the tax onus in regard to the growth in income, and a regressive tax is recognised by a less than proportional rise in the relative onus. So, progressive taxes are seen as removing inequity in income distribution, whereas regressive taxes are found to increase these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, may become less so for the upper-income demographic—especially if a taxpayer is permitted to reduce his tax base by claiming deductions or by removing some particular income components from his taxable income. Proportional tax rates which are applied to lower-income groups could also be more progressive if exemptions of a personal nature are claimed.

Income measured over the period of a given year might not necessarily offer the best measure of taxpaying requirement. For example, transitory increases in income might be saved, and during temporary declines in income a taxpayer might select to provide for consumption by taking from savings. So, if taxation is compared with “permanent income,” it will be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are generally regressive, because the portion of individual income consumed or spent for a specific good declines as the rate of personal income is raised. Poll taxes (also known as head taxes), nominated as a fixed amount per capita, patently are regressive.

It is complicated to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden lays crucially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In considering the economic purpose of taxation, it is relevant to distinguish between varied points of tax rates. The statutory rates are those nominated in law; generally these are marginal rates, but for some cases they are mean rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income increases by one dollar. Thus, if tax liability rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature often contain graduated marginal rates—i.e., rates that rise as income grows. Structured analysis of marginal tax rates should review provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than indicated by the statutory rates. Since marginal rates signify how after-tax income is changed 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 understand the marginal effective tax rate to apply to income from business and capital, because it may be dependant on factors such 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 nothing under a consumption-based tax.

Average income tax rates show the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is necessary for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly increase with income, both because personal allowances are permitted for the taxpayer and dependents and also because marginal tax rates are graduated; on the other side of things, preferential treatment of income received for the most part by high-income households could dampen these effects, forcing regressivity, as signified by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs utilised in projection systems are most often small reflective or transmissive panels set off by a strong arc lamp source. A number of lenses magnifies the reflected or transmitted image then casts it onto the screen. In front-projection systems the LCD is set on the same area of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of more expense and performance might utilise three separated LCD panels, forming separate red, green, and blue images that blend to reflect a coloured picture on the screen.

The increasing need for film displays has granted a special emphasis on the switching speed of liquid crystals. This has demanded the manufacture of devices employing smectic liquid crystals, particular types of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. Inside it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal possesses optically active molecules, and a minor turn up of the optical activity and the slant 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 within the plane of the layers. Thus, there must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been produced for larger passive-matrix displays, but their expense and complexity has hindered them from having any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as aspects in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be employed in time-sequential colour systems, in which expensive colour filters are emulated by a coloured backlight that flashes red, green, and blue in quick speed (around 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods then to a nontransmissive state during the blue period, creating 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 pieces, the chair might be primary. While many other items (save for the bed) are devised to support objects, the chair supports your human form. The term chair is said here in the larger sense, from stool to throne to derivative forms such as a bench or sofa, which should be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as interesting as its history as an art and craft. The chair is not merely a physical support and/or aesthetic piece of art; it was also semiotic of social placement. From the past royal courts there were social differences between being led to a chair with arms, or a chair with a back but without arms, and having to sit on a stool. In the past century, a director’s and/or manager’s chair has risen iconic of superior status, and even in democratic governments the speaker sits on a higher floor.

As a furniture purpose, the chair is used for a number of various makes. There are chairs manufactured to fit man’s age and physical abilities (the high chair, the wheelchair) and to denote his standing in society (the executive chair, the throne). In past times there were chairs used for birth (birth chairs); in the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded up, chairs on wheels, and chairs on runners.

Contemporary lifestyle has demanded special chairs for use in automobiles and aircraft. Each and every one of these chair shapes have perfected to suit to evolving human needs. Because of its particular link with man, the chair comes to its full advantage only when in employ. While it does not make any difference to one’s appreciation of a cupboard or a bureau if there might be things inside or not, a chair is really understood and clearly evaluated with a person sitting on it, for chair and sitter suit the other. Thus the several areas of the chair are given labels like the names of a human shape: arms, legs, feet, back, and seat.

Because the primary role of the chair is to support our human body, its value is evaluated generally on how fully it does fulfill this practical function. Within the design of the chair, the builder is restricted with the static rules and principal measurements. Inside these restrictions, however, the chair creator has extensive freedom.

The history of the chair lasted over an era of several thousand years. There were peoples that had made significant chair shapes, as expressions of the leading work in the industries of skill and design. From those societies, particular note should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of masterful scheme, are known from tomb discoveries. One of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs shaped as akin to those of some animal, a curved seat, with a sloping back supported with vertical stretchers. In this way a strong triangular form was crafted. There was apparently no significant differentiation from the structure of Egyptian thrones and chairs for typical non-royals. The real variation was in the complexity of ornamentation, in the selection of more expensive inlays. The Egyptian folding stool likely was designed as an easily packed seat for army soldiers. As a camp stool this type stayed around for much later times. But the stool also was designed for the purpose of a ceremonial seat, its technical function as a folding stool neglected or forgotten. This can from evidence be observed, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the form of folding stools but aren’t able to be folded as the seats are formed out of wood. The easy structure of the folding stool, composed of two frames that rotate on metal bolts and bear a seat of leather or fabric set between them, can be seen but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this kind is the folding stool, crafted out of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is known not with any ancient object still existing but in a variety of pictorial objects. The archetype is the klismos posited on the Hegeso Stele at the Dipylon burial place just out of Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were seen. These unique legs were considered to be executed from bent wood and were probably had extreme pressure under the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore extremely solid and were overtly denoted.

The Romans adopted the Greek designs; some models of seated Romans are chairs of a heavier and apparently somewhat more crudely constructed klismos. Both types, light and heavy, were popularised during the Classicist period. The klismos chair is seen in French Empire furniture, in English Regency, and in some brands of marked uniqueness around Denmark and Sweden during 1800.

China
The history of the chair in China cannot be traced as far as that of Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged folio of sketches and paintings has been kept, displaying the interiors and exterior of Chinese buildings and the furniture. Also kept of the 16th century are some chairs made of wood or lacquered wood, that bear an astonishing resemblance to designs of past chairs.

Just the same as in Egypt, there were two iconic chair designs in China: a chair with four legs and a folding stool. This chair is seen both with and without arms though never missing its square seat and straight stiles (vertical side supports) to firm the back. In one design, it has been seen, the stiles could be slightly curved over the arms for the purpose of fit the shape of the S-shaped back splat (the basic upright of a back). All three limbs are mortised onto the yoke-like top rail. While the innovation of the Chinese back splat later had an inspiration for English chairs during the Queen Anne period, wooden sections that only just to a particular capability support corner joints (and were loose in the bargain) indicate an element solely to Chinese chairs. The four legs are set through the seat frame, which ends around the rounded staves. All members are round in section or is given rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is uncomfortable and may have a plaited bottom. These chairs demanded of the sitter to hold themselves stiff and upright; for when too much weight is forced on the back, the chair has a tendency to fall over. In patriarchal Chinese houses of this epoch armchairs presumably were reserved only for senior people in the family, for they were given great esteem.

The Chinese folding stool is presumed to have travelled to China from the West. It is not dissimilar very much from the Egyptian and Scandinavian folding stools, but it possesses a change in that the top rail is intricately affixed to the two legs of the stool by a curved member, which is often possessing metal mounts. From a Western understanding the ultimate effect of both furniture styles is stylized. The construction and decoration issues are combined in a way that is at the same time naïve and refined. The piecemeal appearance is an upshot of the fact that the individual members do not look to have been constructed by means of either glue or screws, but are mortised with one another and fixed in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its signature on the chair. Artworks show a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of little pads. The front board and a similar board at the back could be folded after loosening some tiny iron hooks. Thus the chair was a portable piece of furniture while traveling which, during the same period, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be displayed in engravings of the inside of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the form actually was instigated in The Netherlands. Typically, the legs of the chair were smooth, round in section, and of slim measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was produced in vast amounts, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up against a wall. The style asserts itself with its harmonious proportions and fine 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 forms—that is, as brought out in Paris around 1750—conquered most of Europe and was imitated or copied during the mid-20th century. The design owes this popularity to a combination of relaxation and charm. The seat suits to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back disguise 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 relatively thick dimensions; but all the members are deeply molded, all extraneous wood has been taken away, and more expensive items may be further embellished with highly delicate and decorative carving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is generally used for all of the upholstery on the seat, back, and armrests; canework is sometimes used in place of upholstery.

English chairs in the 18th century were more variable in design than the French. The French taste for stylistic uniformity, which spread from the most distinguished circles in Paris and Versailles throughout most of France and became the favourite 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 popularised 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 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, purport 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 operation of a business. Bookkeeping grants the information from which accounts are made but is a different process, required prior to accounting.

Essentially, bookkeeping provides two kinds of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking placement in the entity within a single period.

Management officials, investors, and credit grantors all need such information: management in order to assess 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 for buying, holding, and selling securities; and credit grantors to judge the financial statements of an enterprise in finding whether to accept a loan.

Bits and pieces of financial and numerical records have been seen for almost every civilization with a commercial background. Records of business contracts were found in the archaelogical digs of Babylon, and accounts for both farms and estates had been made in ancient Greece and Rome. The double-entry process of bookkeeping came up with the development of the enterprising republics of Italy, and manuals for bookkeeping were developed within the 15th century in many Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a necessity. The ancestry of bookkeeping, in fact, closely reflects the ancestry of commerce, industry, and government and, partially, assisted to form it. The international spread of industrial and commercial activity needed more sophisticated decision-making processes, which itself demanded more sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government legislation became more important and resulted in even greater demand for information; enterprising firms had to show information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the demand for bookkeeping for their inner operations went up.

While bookkeeping methods can be extremely detailed, it is all based on two types of books used in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger should have the information of individual accounts. The daily records from the journals are written in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are created from the trial balance posted within the ledger. The point of the income statement or profit-and-loss statement is to show an analysis of those changes that occurred in the business equity as a result of the transactions of the period. The balance sheet gives the financial condition of the company at any 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 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. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
