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

The most common question customers ask when looking for a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, an acronym 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 different types available, it can be difficult for clients to choose between the two technologies. Ultimately LCD projectors provide far better image quality and colour accuracy. The following article will tell you why DLP projectors struggle with reproducing an equal grade of image quality.

Imagine a set of blinds in your room covering your bedroom window. By twisting a rod you can have the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector behaves. Each pixel operates like a unique 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 when the projector is turned on to when the image reaches your screen is ultimately important with regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by switching each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. A significant point to understad about LCD projectors is that all three colours are delivered onto your screen all at once. The way a DLP projector works is totally different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of making 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 construct the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into a complete image. In LCD projectors, all colours are available all the time to form the best brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some manufacturers have put a white segment for the colour wheel to improve overall brightness, but this further lessens colour accuracy.

I read in forums all the time that DLP offers a higher contrast ratio and as such must be superior 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 system is able to produce. DLP projectors do possess high contrast specifications compared to most LCD projectors. Initially, this can seem to be a plus, however, in truth, the true black level is determined by the ambient light in the room while the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you wish to project includes moving images, DLP projection technology also has image errors, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this downside because all colours are sent at once. DLP developers have come up with 3DLP solutions using 3 chips to solve the colour break up problem, but the expense of these projectors make them impractical for most businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and remember when they taught you how different colours of light refract differing amounts when shone through the same lens. The downside 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 different and refract light at different levels. Most of the time with a DLP projector, some extra yellow colour will come through above and an extra blue will come through below an image containing something as simple as a straight black line. In manufacturing LCD projectors can be set to minimize these effects on the projected image, because each colour is projected on its own LCD panels.

The sole true benefit (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant to portability and cannot be traded off against the image superiority of LCD projectors. If overall picture quality is important to you, then the answer is a no-brainer. Go with an LCD projector! LCD projectors will constantly make bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the early yacht had been a leisure craft used first by royalty and then by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private matches. English yachting originated 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 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), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting became popular for the affluent and royalty, but after that time the fashion did not last.

The first yacht group in the British Isles, the Water Club, was started at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held large naval panoply and rigour. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, largely as a social club, until 1765, and in 1828, when merging with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered fashion on the Thames around the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British racing. The club at Cowes became the Royal Yachting Club, again at the rise of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing races for great stakes were held, and the social life was lovely. Eventually 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 continued when the English had dominance. Sailing was mostly for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised 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 organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The design of large yachts was initially heavily impacted by the success of America, which was designed by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its victory at Cowes in 1851. The first yachts were not designed and manufactured in a contemporary sense, with only a model used. Not until the later half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the application of the study of aerodynamics do for the structure of sails and rigging what such study had earlier done for hulls.

Because almost all sailboats had been individually built, there came a requirement for handicapping boats before the one-design class boats were made. Hence, a rating rule was created, which resulted in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the fastest flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are manufactured to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even basis with no handicapping at all. A prime example is the uniform International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

For the time that yachting was done largely for the royal and the wealthy, money was no issue, and the size of boats developed, in both length and weight. The promotion and preference of smaller boats came in the later 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 voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of small craft. Later in the 20th century, notably after World War II, smaller racing and leisure yachts became commonplace, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, when steam started to take the place of sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were increasingly employed in personal boats. Bigger power yachts were developed to a high standard, and long-distance travel turned into a preferred activity of the wealthy. The first power yachts were paddle-wheel boats; these then gave way to boats powered by the fully submerged screw or propeller sort of propulsion. As in the case of naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for a number of years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of more sizeable steam yachts. Notably within these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 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 gave active service in World War II.

As bigger and more dependable internal-combustion engines were developed, many large yachts started using them for power. The establishment of the diesel engine, employing heavy oil for fuel, progressed from World War I. From the decade that followed, big power-yacht manufacture blossomed, climaxing in the Orion (1930) at 3,097 tons. In that period the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of big power yachts fell away after 1932, and the fashion thereafter was in preference of smaller, less expensive craft. From World War II, lots of small naval craft were sold to private owners for conversion to yachts. By the late 20th century, yachting has become a internationally beloved competition enjoyed by thousands of yachtsmen individually sailing and maintaining their own small leisure craft. The number of yachts and sailors is increasing steadily, not only in the traditional locations by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is the kind that imposes the same relative onus on all taxpayers—i.e., where tax liability and income move in equal proportion. A progressive tax is recognisable by a greater than proportional increase in the tax onus relative to the increase in income, and a regressive tax is characterized by a less than proportional growth in the comparable liability. Therefore, progressive taxes are regarded as fighting the lack of equality in income distribution, but regressive taxes might result in an increase these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so for the upper-income class—particularly if a taxpayer is able to lessen his tax base by nominating deductions or by leaving out some particular income elements from his taxable income. Proportional tax rates which are applied to lower-income groups would also be more progressive if such exemptions of a personal nature are made.

Income measured over the course of a given period does not necessarily come up with the most suitable measure of taxpaying status. For example, transitory growth in income can be saved, and during temporary declines in income a taxpayer may decide to provide for consumption by decreasing savings. Ergo, if taxation is held in comparison with “permanent income,” it would be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (excepting luxuries) are usually regressive, because the dissemination of one’s income consumed or spent for specific goods decreases as the rate of personal income increases. Poll taxes (also known as head taxes), levied as a flat amount per capita, clearly are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of a lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden rests crucially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In regarding the economic effect of taxation, it is relevant to distinguish between differing ideas of tax rates. The statutory rates will include those specified in legislation; often these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income increases by one dollar. Hence, if tax onus grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax statutes commonly contain graduated marginal rates—i.e., rates that rise as income increases. Careful analysis of marginal tax rates need to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than specified by the statutory rates. Since marginal rates signify how after-tax income changes in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, since 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 determines 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 considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally rise with income, both because personal allowances are allowed for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households might dampen these effects, allowing regressivity, as displayed by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs built in projection systems are typically small reflective or transmissive panels lit by a bright arc lamp source. A number of lenses enlarges the reflected or transmitted image and casts it on the screen. For front-projection systems the LCD is situated on the same side of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of more expense and capability might use three separate LCD panels, creating separate red, green, and blue images that blend to make a coloured image 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 development of objects build with smectic liquid crystals, some kinds of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. Within it the liquid crystal molecules are set out in perpendicular layers to the substrate planes, which are separated by one or two micrometres, and within the layers the molecules are slanted, as shown in the figure. The host liquid crystal contains optically active molecules, and a subtle consequence of the optical activity and the slant 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 through the plane of the layers. Thus, there exists 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 corresponding sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been produced for big passive-matrix presentations, but their expense and intricacy has hindered them from enjoying any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their quick reacting allows them to be made use of in time-sequential colour systems, in which highly expensive colour filters are emulated by a coloured backlight that flashes red, green, and blue in quick succession (approximately 100 cycles a second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods then to a nontransmissive state during the blue period, displaying the upshot 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 could be the most important. While most of the other items (save for the bed) are meant to support objects, the chair supports your human form. The term chair can be used here in the larger sense, from stool to throne to developed types such as a bench or sofa, which should be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinuishable.

The social history of the chair is as intriguing as its history as a creative art. The chair is not merely a physical support and aesthetic artwork; it can also be semiotic of social placement. From the old royal courts there were significant connotations between being seated on a chair with arms, or a chair with a back but no arms, and having to utilise a stool. In the past century, the director’s or manager’s chair has been regarded as an indicator of superior status, like in democratic governments the speaker sits on a higher floor.

In its furniture purpose, the chair ranges from a wealth of various purposes. There are chairs manufactured to match man’s age and physical condition (the high chair, the wheelchair) and to denote his standing in society (the executive chair, the throne). From historical days there were chairs for births (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs for use in automobiles and aircraft. Each and every one of these chair shapes has perfected to suit to different human uses. Due to its significant importance with man, the chair lives to its full significance only when utilised. Although it does not make any difference to one’s appreciation of a cupboard or a set of drawers if there is anything inside or not, a chair is really seen best and judged best by a person utilising it, because chair and sitter complement the other. Thus the individual parts of a chair have been given labels according to the limbs of our human shape: arms, legs, feet, back, and seat.

Because the clear role of the chair is to support your body, its value is evaluated principally by how well it fulfills this practical role. In the structure of the chair, the maker is limited under some static regulations and principal measurements. Within these rules, however, the chair creator has marvellous freedom.

The history of the chair covers dates of several thousand years. There were cultures that had individual chair shapes, seen of the leading task in the spheres of handling and design. In these civilisations, special 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of masterful scheme, are now known from findings made in tombs. First of them is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair has four legs shaped like those of some animal, a curved seat, leading to a sloping back supported with vertical stretchers. In this design a strong triangular form was made. There seems to be no significant difference in the creation of Egyptian thrones and chairs for typical citizens. The general change existed in the type of ornamentation, in the particulars of costly inlays. The Egyptian folding stool likely was manufactured to be an easily portable seat for army soldiers. As a camp stool that stool stayed around during much later points. But the stool then was created as the purpose of a ceremonial seat, its mechanical function as a folding stool simply forgotten. This can now be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but can’t be folded as the seats are worked of wood. The plain manufacture of the folding stool, consisting of two frames that spin on metal bolts and bear a seat of leather or fabric secured between them, reappeared some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this type is the folding stool, of ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is seen not as any ancient fossil still around but as in a trove of pictorial material. The archetype is the klismos displayed on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of which can be visible. These curved legs were thought to be crafted with bent wood and were probably needed to bear extreme pressure with the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very strong and were plainly drawn.

The Romans borrowed from the Greek designs; quite a few statues of seated Romans show chairs of a denser and apparently rather less intricately built klismos. Both designs, the light and heavy, were brought back in the Classicist era. The klismos style can be seen in French Empire styles, in English Regency, and in some particular types of marked originality of Denmark and Sweden circa 1800.

China
The ancestry of the chair in China can not be tracked as long as the ancestry of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unbroken serial of images and artworks was kept safe, with images of the interiors and outer parts of Chinese buildings and the kinds of furniture. Kept also of the 16th century are a trove of chairs constructed from wood or lacquered wood, that display an intriguing resemblance to designs of ancient chairs.

Like in Egypt, there were two major chair forms in China: a chair having four legs and a folding stool. The four-legged chair is designed both with or without arms but always with a square seat and straight stiles (standing side supports) to give support to the back. In one design, however, the stiles had been lightly curved over the arms in order to fit the shape of the S-shaped back splat (the centre upright of the chairback). The three parts are mortised onto the yoke-like top rail. Although the idea of the back splat exercised an introduction for English chairs during the Queen Anne period, wooden members that could merely to a restricted limit reinforce corner joints (and then are loose to top that off) are a design signatory to Chinese chairs. The four legs sit through the seat frame, which ends around the rounded staves. Members are round in section or have rounded edges—references maybe to the bamboo tradition. The seat is not pleasant and occasionally had a plaited form. These chairs required of the sitter to stay stiff and upright; if too much weight is pushed on the back, the chair has a way of toppling over. In patriarchal Chinese homes of this epoch armchairs probably were reserved only for the senior people in the family, for they were esteemed greatly.

The Chinese folding stool is thought to have been brought to China from the West. It is not dissimilar that much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is delicately held to the two legs of the stool by a curved member, which is more often than not seen with metal mounts. From a Western point of view the resulting effect of these two furniture designs is stylized. The constructive and decorative aspects are combined in a way that is at the same time naïve and refined. The pieced-together appearance is an outcome of the fact that the individual items do not look to have been constructed by means of either glue or screws, but had been mortised on one another and held in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its signature on the chair. Artworks project a style of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in the layers, stitched to bring up a pattern of little pads. The front board and a related board in the back could be folded after unscrewing some tiny iron hooks. Thus the chair was an easily portable piece of furniture for traveling which, at the same time, gave 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 the interior of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair can also be found in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not certain that the innovation actually started in The Netherlands. Typically, the legs of the chair were smooth, round in section, and of slim dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in impressive numbers, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of such chairs lined up by a wall. The style asserts itself by virtue of its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is, as created in Paris around 1750—disseminated over most of Europe and was imitated or copied in the mid-20th century. The model owes such popularity to a combination of relaxation and elegance. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions are made between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them use wood of quite thick measurements; but each member is deeply molded, all extra wood has been removed, and more expensive designs might be further embellished with special delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all of the upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

English chairs of the 18th century were more varied in form than the French. The French manner for stylistic uniformity, which lead from the aristocratic circles in Paris and Versailles through 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 well-known and was widely distributed throughout the world.

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

In cheaper products 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 recordkeeping of the money values of the function of a business. Bookkeeping creates the numbers from which accounts are prepared but is a different process, required prior to accounting.

Basically, bookkeeping records two areas of information: (1) the current value, or equity, of an entity and (2) any changes in value—profit or loss—taking placement in the enterprise from a single time.

Management officials, investors, and credit grantors all need to have such information: management to understand the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to analyse the upshots of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an enterprise in finding whether to give a loan.

Pieces of financial and numerical charts have been seen for almost every society with a commercial backbone. Records of commercial contracts were found in the remains of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The two-entry manner of bookkeeping came up with the furthering of the business republics of Italy, and tutorial books for bookkeeping were created during the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial bookkeeping a requirement. The ancestry of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, partially, helped to form it. The international spread of industrial and commercial activity called for higher professional decision-making methodology, which in its turn required more sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government legislature became more significant and resulted in greater demand for information; businesses had to have information available to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the need for bookkeeping for their own inner operations became higher.

Though bookkeeping procedures can be very complex, it is all based on two styles of books used in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger should have the records of individual accounts. The daily records from the journals are entered in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted from the ledger. The point of the income statement or profit-and-loss statement is to show an analysis of the changes that have occurred in the business equity resulting from the transactions of the period. The balance sheet shows the financial position of the business at the particular day in terms of 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.
