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

The most common question customers ask when buying a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two top projector imaging technologies. With so many brands and models available, it can be challenging for the buyer to choose between these technologies. Ultimately LCD projectors have far superior image quality and colour accuracy. The next part of this article will tell you why DLP projectors struggle with reproducing a comparable grade of image quality.

Imagine a set of blinds in your household on your bedroom window. By pulling on a rod you can turn the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector functions. Each pixel functions like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the time the projector turns on to when the picture reaches your screen is extremely significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 individual LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to create the projector image. An important point to know about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector runs is very different and even the way an image comes out is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of 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 construct the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into a whole image. From LCD projectors, all colours are available all the time to deliver the best brightness and great colour accuracy. In DLP, only one colour is available at once, and so resulting in lower colour brightness and accuracy. Some designers have included a white segment in the colour wheel to improve brightness generally, but this further detracts from colour accuracy.

I find in forums all the time that DLP has a higher contrast ratio and thus must be better quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the technology is capable of. DLP projectors do possess high contrast specifications as compared to the majority of LCD projectors. At first glance, this can seem to be a benefit, however, in real life, the true black level is determined by the ambient light in the room in which the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you wish to see includes moving images, DLP projection technology also has image marks, or ‘artifacts’. The most typical 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 up between the time red, blue and green colours are shone. LCD projectors do not have this downside because all colours are projected with the others. DLP manufacturers have come up with 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them impractical for most businesses and consumers.

Another difference between LCD and DLP is how they compensate for the refractive qualities of light. Take yourself back to high school science, and recall how the different colours of light refract various amounts when passing through the same lens. The downside with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light at different levels. Usually with a DLP projector, a spill of yellow colour will come through above and some blue will be projected below an image containing something as simple as a single black line. In manufacturing LCD projectors can be adjusted to take away these effects on the projected image, because each colour is processed on separate LCD panels.

The sole veritable buy point (excluding price) with buying a DLP projector is its smaller overall size and weight. However, this is only relevant with regard to portability and needs to be traded off against the image superiority of LCD projectors. If overall picture quality is crucial to you, then the choice is a no-brainer. Go for an LCD projector! LCD projectors will definitely produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht was a pleasure craft used mostly by royalty and later by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), made additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting rose as classy for the affluent and aristocracy, but after that point the fashion did not last.

The first yacht association in the British Isles, the Water Club, was started around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and held great naval panoply and gravity. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imaginary enemy. The club went on, mostly as a social club, until 1765, and in 1828, after conglomerating with other groups, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered fashion on the Thames about the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been initiated 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 continuing site of British yachting. The society at Cowes became the Royal Yachting Club, likewise at the rise of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the club life was superlative. It came to be that the Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English gained control. Sailing was mostly for fun and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in the 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 began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The craft of bigger yachts was initially largely put upon by the win 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 success at Cowes in 1851. Early 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 called naval architecture come about. Not until the 1920s did the application of the science of aerodynamics do for the structure of sails and rigging what such study had earlier done for hulls.

Because almost all sailboats were individually custom-built, there arose a need for handicapping boats before the one-design class boats were designed. Hence, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and amended in 1919. In modern times, one of the rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to single specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing such boats can be done on an even basis with no handicapping at all. A perfect example is the uniform International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

As long as yachting belonged mostly for the aristocracy and the affluent, cost was no object, and the size of boats increased, in both length and weight. The rise and popularity of smaller craft 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of less sizeable boats. Following this in the 20th century, for the larger part after World War II, smaller racing and recreational boats became commonplace, down to the dinghy, a favourite 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
After the decade 1840–50, at which point steam was set to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure boats. Sizeable power yachts were progressed to a high element, and long-distance travel turned into a favoured occupation of the affluent. The earliest power yachts were paddle-wheel boats; these then gave rise to boats powered by the fully submerged screw or propeller kind of propulsion. As in the case of naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for many years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were only power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the construction of more sizeable steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 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 gave active service for World War II.

As larger and more dependable internal-combustion engines were developed, many big craft began using them for power. The establishment of the diesel engine, using heavy oil for fuel, advanced during World War I. From the decade after, big power-yacht building grew, hitting a climax 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 construction of large power craft fell away from 1932, and the trend after that was for smaller, less costly craft. After World War II, many small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a widespread loved sport enjoyed by thousands of yachtsmen personally sailing and keeping their own small leisure craft. The number of craft and sailors has increased steadily, not only in the traditional areas on the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are categorized by the impact they have on the allocation of income and wealth. A proportional tax is a kind that impinges the same relative burden on each taxpayer—i.e., in the case where tax liability and income grow in the same scale. A progressive tax is characterized by a larger than proportional rise in the tax liability in regard to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the related liability. Therefore, progressive taxes are thought of as removing inequity in income distribution, but regressive taxes are believed to have the result of increasing these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so within the upper-income group—particularly if a taxpayer is able to lessen his tax base by nominating deductions or by leaving out some certain income aspects from his taxable income. Proportional tax rates when applied to lower-income groups would also be more progressive if exemptions of a personal nature are claimed.

Income measured over a given year may not definitely give the most appropriate measure of taxpaying requirements. For example, transitory rises in income can be saved, and during temporary declines in income a taxpayer might choose to finance consumption by decreasing savings. Thus, if taxation is compared along with “permanent income,” it should be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (with the exception of those on luxuries) are usually regressive, because the share of individual income consumed or spent on a specific good decreases as the level of personal income increases. Poll taxes (also called head taxes), levied as a fixed amount per capita, clearly are regressive.

It is complicated to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of a lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden is dependant crucially 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 relevant to distinguish between various concepts of tax rates. The statutory rates will include those nominated in legislature; generally these are marginal rates, but for some cases they are mean rates. Marginal income tax rates signify the fraction of incremental income that is taken by taxation when income increases by one dollar. Thus, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates need to consider provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates display how after-tax income increases or decreases 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 know the marginal effective tax rate applied to income from business and capital, since it may be dependant on such considerations 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 nothing under a consumption-based tax.

Average income tax rates indicate the portion of total income that is paid in taxation. The pattern of average rates is the one that is necessary 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 grow with income, both because personal allowances are granted for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households might dampen these effects, forcing regressivity, as signified by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs utilised in projection systems are typically small reflective or transmissive panels set off by a forceful arc lamp source. A line of lenses expands the reflected or transmitted image and sends it onto a screen. For front-projection systems the LCD is situated on the same side of the screen as the viewer, however in rear-projection systems the screen is lit from behind. Projectors of greater expense and performance sometimes use three discrete LCD panels, reflecting separate red, green, and blue images that combine to form a coloured image on the screen.

The growing need for film displays has granted a growth in emphasis on the switching speed of liquid crystals. This has necessitated the creation of items using smectic liquid crystals, certain ones of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. Within it the liquid crystal molecules are cast in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a subtle consequence of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, similar to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Thus, there is a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The corresponding change in optical properties can create a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been marketed for larger passive-matrix presentations, but their expense and detail has hindered them from enjoying any significant progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their quick response allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast succession (about 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state during the red and green periods then to a nontransmissive state in the blue period, creating the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture items, the chair could be the primary one. While the majority of other pieces (apart from the bed) are created to support objects, the chair supports the human form. The term chair should be used here in the most common sense, from stool to throne to developed kinds for example the bench and sofa, which should be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously defined.

The social history of the chair is as stimulating as its history as a creative craft. The chair is not simply a physical support or an aesthetic object; it was historically a symbol of social place. In the past royal courts there were important signifiers between being led to a chair with arms, or a chair with a back but without arms, or worse having to cope with a stool. From the 20th century, a director’s and/or manager’s chair has risen a symbol of superior position, as well as in democratic government meeting the speaker sits on a raised floor.

In its furniture construction, the chair is employed for a variety of various forms. There are chairs created to attend to man’s age and physical form (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). During the past there were chairs to be born in (birth chairs); since 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. We make chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed new chairs for automobiles and aircraft. All of these chair shapes has changed to fit to changing human requirements. Because of its significant importance with man, the chair comes to its full meaning only when used. Though it does not make a difference to one’s appreciation of a cupboard or a bureau if there are items inside or not, a chair is really seen best and fairly tested by a person sitting on it, for chair and sitter suit each other. Thus the different limbs of a chair are given names corresponding to the elements of our human form: arms, legs, feet, back, and seat.

Because the simple job of a chair is to support our body, its value is judged principally for how fully it fulfills this practical job. Within the construction of a chair, the carpenter is limited under some static regulations and principal measurements. Through these limitations, however, the chair creator has extensive freedom.

The history of the chair lasted over an era of several thousand years. There is evidence of civilizations that made significant chair types, as seen of the foremost craft in the arenas of technique and design. In these peoples, particular note 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of expert scheme, are now known from tomb findings. First of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs crafted not unlike those of a chosen animal, a curved seat, and with a sloping back supported by vertical stretchers. In this way a durable triangular structure was obtained. There was to our knowledge no marked difference in the design of Egyptian thrones and chairs for regular peasantry. The simple change existed in the kind of ornamentation, in the particulars of costly inlays. The Egyptian folding stool probably was developed as an easily portable seat for officers. As a camp stool the form persisted during much later periods of time. But the stool also was created for the use of a ceremonial seat, its technical role as a folding stool ignored or forgotten. This can from today’s evidence be found, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but cannot be folded as the seats were worked with wood. The simplistic build of the folding stool, consisting of two frames that rotate on metal bolts and hold a seat of leather or fabric fastened between them, then appeared at some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of these is the folding stool, from ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is seen not with any ancient item still existing but from a variety of pictorial objects. The most recognisable is the klismos depicted on the Hegeso Stele at the Dipylon burial location 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 those could be shown. These curved legs were likely to have been crafted of bent wood and were likely to have been put under a large amount of pressure with the weight of the sitter. The joints securing the legs to the frame of the seat were therefore super stable and were clearly pointed out.

The Romans embued the Greek chair; some models of seated Romans offer designs of a heavier and are a somewhat less delicately crafted klismos. Both styles, light or heavy, were popularised in the Classicist epoch. The klismos chair is found in French Empire design, in English Regency, and in some special kinds of considerable iconicism within Denmark and Sweden during 1800.

China
The history of the chair in China can not be traced as well as the history of chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unbroken collection of drawings and artworks has been kept, with images of the inside and exteriors of Chinese households and the designs of furniture. Also kept since the 16th century are a number of chairs made of wood or lacquered wood, that show an amazing resemblance to designs of ancient chairs.

As in Egypt, there existed two particular chair designs in China: a chair that had four legs and a folding stool. That chair is seen both with and without arms but always having its square seat and straight stiles (standing side supports) to give support to the back. In one kind, it has been seen, the stiles had been lightly curved over the arms in order to suit the form of the S-shaped back splat (the central upright of its back). Each of the three parts had been mortised into the yoke-like top rail. While the design of the back splat then had a foundation for English chairs of the Queen Anne period, wooden items that could only to a particular capability embolden corner joints (as well as being loose in the bargain) represent a design solely to Chinese chairs. The four legs sit through the seat frame, which closes around the rounded staves. Each member is round in section or have rounded edges—referable maybe to the bamboo tradition. The seat is unpleasant to sit in and had on occasion a plaited seat. These chairs required of the sitter to remain stiff and upright; for if too much weight is placed on the back, the chair has a way of falling over. In patriarchal Chinese households of this era armchairs likely were kept only for senior people in the family, for they were given great respect.

The Chinese folding stool is understood to have come to China from the West. It does not vary so very much from the Egyptian and Scandinavian folding stools, but it possesses a change in that the top rail is elegantly held to the two legs of the stool by means of a curved member, which is usually provided with metal mounts. From a Western viewpoint the overall effect of both these furniture styles is stylized. The structure and decorative issues are combined in a manner that is simultaneously naïve and refined. The piecemeal appearance is an outcome of the fact that the individual items do not seem to have been put together by means of either glue or screws, but have been mortised onto one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its name on the chair. Artworks project a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of little pads. The front board and a corresponding board at the back could be folded after loosening some little iron hooks. Therefore the chair was a readily portable piece of furniture when traveling which, in the same period, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be evidenced in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair might also be made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the style actually was instigated in The Netherlands. Generally, the legs of the chair are 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 produced in large quantities, as can be seen from one of Abraham Bosse’s engravings, in which there is a 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 bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is, as brought out in Paris around 1750—spread through most of Europe and was imitated or copied in the mid-20th century. The style owes the popularity to a combination of comfort and elegance. The seat conforms to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back conceal all the joints, which are constructed strongly on craftsmanlike principles in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those are constructed from wood of relatively thick density; but every member is deeply molded, all extraneous wood has been removed, and finer designs can be further embellished with very delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for all of the upholstery on the seat, back, and armrests; cane is sometimes used instead of upholstery.

English chairs in the 18th century were more variable in style than the French. The French manner for stylistic uniformity, which lead from the aristocratic 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 popularised 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 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, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping provides the figures from which accounts are written but is a separate process, prior to accounting.

Basically, bookkeeping records two kinds of information: (1) the current value, or equity, of an entity and (2) changes in value—profit or loss—taking place in the entity within a given period of time.

Management officials, investors, and credit grantors all demand this information: management so as to assess the results 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 in order to regard the financial statements of an enterprise in deciding whether to allow a loan.

Traces of financial and numerical records can be found for almost every state with a commercial backbone. Records of trade contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The double-entry style of bookkeeping began with the furthering of the enterprising republics of Italy, and instruction books for bookkeeping were created during the 15th century in various Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a necessity. The ancestry of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, in part, assisted forming it. The global revolution of industrial and commercial activity needed greater sophisticated decision-making processes, which then needed better sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government regulation became more detailed and resulted in greater need for information; enterprising firms 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 become larger, and the need for bookkeeping for their own inner departmental operations became higher.

Although bookkeeping procedures can be very multifaceted, all of it is based on two types of books used in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger contains the records of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are made from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to provide an analysis of any changes that have occurred in the enterprise equity from the operations of the period. The balance sheet provides the financial position of the corporation at the particular point 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 yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
