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

The most common question asked when looking for a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, standing 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 models available, it can be overwhelming for consumers to choose between those technologies. The fact is that LCD projectors give far better image quality and colour accuracy. The article below tells you why DLP projectors struggle with bringing up the same rate of image quality.

It’s like a set of blinds in your household on 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 such is exactly how an LCD projector operates. Each pixel operates like a unique shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element works 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 extremely significant in 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 transfer the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by turning each pixel on and off. The pixels are then simultaneously processed in a glass prism to deliver the projector image. Something to understad about LCD projectors is that all three colours are sent onto your screen all at the same time. The way a DLP projector runs is very different and even the final product of how an image appears is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then pull together each coloured element of the image into a full image. From LCD projectors, all colours are available all the time to offer the top level of brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some DLP manufacturers have included a white segment in the colour wheel to improve brightness generally, but this also detracts from colour accuracy.

I hear in forums all the time that DLP has a higher contrast ratio and as such must be better. For those who do not know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of. DLP projectors do offer high contrast specifications as compared to many LCD projectors. At one glance, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to view has moving images, DLP projection technology can also create image imperfections, 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 keep changing between the time red, blue and green colours are pulled up. LCD projectors do not have this disadvantage because the colours are projected at once. DLP developers have developed 3DLP solutions using 3 chips to resolve the colour break up problem, but the cost of these projectors make them not practical for the majority of businesses and consumers.

Another variance between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and recall when they taught you how different colours of light refract varied amounts when shone through the same lens. The disadvantage with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in different ways. Generally with a DLP projector, a spill of yellow colour will come through above and a spill of blue will come through below an image as simple as a lone black line. During manufacturing LCD projectors can be set to minimize these effects on the projected image, because each colour is refracted on its own LCD panels.

The isolated actual buy point (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant to mobility and must be traded off against the image benefits of LCD projectors. If resulting picture quality is crucial to you, then the decision is easy. Go with an LCD projector! LCD projectors will always produce bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the first yacht became 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. Racing yachts was incidental, arising as private games. English yachting started 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 sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), 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 wager. Yachting became popular among the rich and aristocracy, but after that point the habit did not last.

The first yacht club in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and had large naval panoply and rigour. The closest thing to a race was the “chase,” for which the “fleet” pursued an imaginary enemy. The club went on, largely as a social club, until 1765, and in 1828, after joining with other organisations, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated fashion on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been initiated at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British racing. The club at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing races for great bets 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 was first accomplished with the Dutch in New York in the 17th century and went on when the English held control. Sailing was for the most part for leisure and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a benchmark of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of sizeable yachts was originally heavily impacted by the win 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 built in today’s sense, with only a model for an outline. Not until the latter half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the use of the research of aerodynamics do for the design of sails and rigging what science had done earlier for hulls.

Because almost all sailboats had to be individually built, there was a need for handicapping boats as this was previous to the one-design class boats were built. Hence, a rating rule came into being, which is found in the International Rule, accepted in 1906 and amended in 1919. In the present day, one of the most rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to standard requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even par with no handicapping required. A prime example is the uniform International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

For the time that yachting belonged largely for the nobility and the wealthy, money was no object, and the size of boats increased, in both length and weight. The promotion and preference of smaller yachts happened in the second half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of small yachts. Thereafter in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, in which steam was set to emulate sail power in public boats, the steam engine, and later the internal-combustion engine, were employed increasingly in personal craft. Large power yachts were progressed to a high degree, and long-distance cruising turned into a favourite occupation of the wealthy. The earliest power yachts were paddle-wheel boats; these then made way to those powered by the fully submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries carrying both sail and power were the yacht standard for many years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were only power yachts containing gasoline or diesel engines.

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

As bigger and more dependable internal-combustion engines were created, many big boats were using them for power. The development of the diesel engine, employing heavy oil for fuel, advanced from World War I. In the decade after that, bigger power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of large power craft lessened in 1932, and the style after that was in preference of smaller, less pricey yachts. Following World War II, a lot of small naval craft were sold to private owners for conversion to yachts. By the late 20th century, yachting is a globally popular activity enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small pleasure craft. The amount of craft and owners is increasing steadily, not only in the traditional areas along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are categorized by the impact they have on the distribution of income and wealth. A proportional tax is a tax that applies the same relative onus on all taxpayers—i.e., where tax liability and income grow in the same levels. A progressive tax is characterizable by a higher than proportional increase in the tax onus in regard to the growth in income, and a regressive tax is characterized by a less than proportional rise in the relative liability. Hence, progressive taxes are regarded as fighting the lack of equality in income distribution, whereas regressive taxes are found to result in an increase these inequalities.

The taxes that are normally regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so for the upper-income demographic—in particular if a taxpayer is able to reduce his tax base by declaring deductions or by leaving out certain income aspects from his taxable income. Proportional tax rates if applied to lower-income demographics would also be more progressive if such personal exemptions are made.

Income measured over the period of a year does not definitely offer the best measure of taxpaying requirement. For example, transitory growth in income can be saved, and during temporary declines in income a taxpayer could choose to pay for consumption by decreasing savings. Ergo, if taxation is made comparable alongside “permanent income,” it would be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (save those on luxuries) are mostly regressive, because the spread of individual income consumed or spent for a specific good lessens as the level of personal income increases. Poll taxes (also known as head taxes), levied as a flat amount per capita, clearly are regressive.

It is not simple to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant 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 important to differentiate between several concepts of tax rates. The statutory rates will be specified in the legislation; commonly these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income grows by one dollar. Thus, if tax burden increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislation commonly contain graduated marginal rates—i.e., rates that grow as income rises. Careful analysis of marginal tax rates are required to regard provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers 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 signify how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for regarding incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, because it may be reliant on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates determine the part of total income that is demanded in taxation. The pattern of average rates is the one that is important for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually rise with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; on the flip side, preferential treatment of income received predominantly by high-income households can dampen these effects, allowing regressivity, as indicated by average tax rates that lessen as income grows.

The Development of Data Projectors

The LCDs used for projection systems are generally small reflective or transmissive panels lit by a bright arc lamp source. A line of lenses expands the reflected or transmitted image then displays it on the screen. For front-projection systems the LCD is located on the same side of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of greater expense and capacity might utilise three distinct LCD panels, casting separate red, green, and blue images that blend to create a coloured image on the screen.

The growth in desire for pictographic presentations has granted a growing emphasis on the switching speed of liquid crystals. This has necessitated the development of devices using smectic liquid crystals, some kinds of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. Within it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are on a slant, as displayed in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible outcome of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, comparable 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. Therefore, there has to be 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 right sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been marketed for large passive-matrix presentations, but their cost and detail has impeded them from creating any great impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as parts in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be made use of in time-sequential colour systems, in which high cost colour filters are replaced by a coloured backlight that flashes red, green, and blue in fast succession (approx 100 cycles a second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods and then to a nontransmissive state during the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture needs, the chair might be the imperative one. While many other forms (apart from the bed) are devised to support objects, the chair supports our human form. The term chair is meant to be looked upon here in the larger sense, from stool to throne to complex types for example the bench and sofa, which can be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly definitive.

The social history of the chair is as stimulating as its history as a creative craft. The chair is not simply a physical support and/or aesthetic artwork; it historically is a symbol of social standing. In the historical royal courts there were significant signifiers between being seated on a chair with arms, on a chair with a back but without arms, and having to squat on a stool. Since the recent century, the director’s or manager’s chair has risen an identifier of superior position, like in democratic government debate the speaker sits on a higher floor.

As a furniture form, the chair can be employed for a number of various forms. 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). During historical days there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). We design chairs with one, two, three, and 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.

Contemporary lifestyle has demanded unique chairs for use in automobiles and aircraft. Each and every one of these chair forms have been perfected to conform to differing human uses. From its close association with man, the chair exists to its full importance only when utilised. Although it doesn’t make a difference to one’s appreciation of a cupboard or a dresser drawers whether there are items inside or not, a chair is understood best and fairly judged by a person sitting in it, for chair and sitter require the other. Thus the different elements of the chair are named as the limbs of our human body: arms, legs, feet, back, and seat.

Because the fundamental work of a chair is to support the human body, its credit is judged generally for how well it fulfills this practical function. In the structure of a chair, the carpenter is restricted with the static legislation and principal measurements. Under these limits, however, the chair builder has large freedom.

The history of the chair was a period of several thousand years. There were societies that have created unique chair forms, expressive of the leading work in the spheres of handling and art. Among those peoples, special note needs to 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 upshot of expert craft, are today known from tomb discoveries. The first of the two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair has four legs crafted akin to those of a particular animal, a curved seat, and with a sloping back supported with vertical stretchers. From this design a stable triangular design was obtained. There was to our understanding no noteworthy variation between the design of Egyptian thrones and chairs for ordinary citizens. The general change was in the level of ornamentation, in the particulars of pricier inlays. The Egyptian folding stool in all probability was created to be an easily portable seat for army officers. As a camp stool this form stayed around during much later points in time. But the stool also played the use of a ceremonial seat, its mechanical job as a folding stool neglected or forgotten. This can today be found, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the form of folding stools but can’t be folded because the seats were worked with wood. The simple build of the folding stool, consisting of two frames that rotate on metal bolts and support a seat of leather or fabric set between them, came up but some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this type is the folding stool, made from ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is known not in any ancient specimen still extant but as found in a variety of pictorial items. The best recognised is the klismos seen on the Hegeso Stele at the Dipylon burial ground outside Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs were displayed. These curving legs were possibly executed out of bent wood and were probably subjected to extreme pressure from the weight of the sitter. The joints securing the legs to the frame of the seat would have been therefore super stable and were overtly drawn.

The Romans borrowed from the Greek chair; designs of casts of seated Romans are evidence of a heavier and are a somewhat less delicately designed klismos. Both features, the light or the heavy, were revived within the Classicist epoch. The klismos design is found in French Empire furniture, in English Regency, and in some particular kinds of marked individuality in Denmark and Sweden during 1800.

China
The ancestry of the chair in China cannot be traced as long as the history of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) a full series of images and artworks has been preserved, showing the inside and outside of Chinese houses and the kinds of furniture. Also kept since the 16th century are a collection of chairs of wood or lacquered wood, that show an interesting likeness to designs of previous chairs.

As was the case in Egypt, there existed two fundamental chair forms in China: a chair having four legs and a folding stool. That chair was found both with and without arms but never without the square seat and straight stiles (vertical side supports) to give support to the back. In one image, it has been found, the stiles had been slightly curved above the arms to suit the structure of the S-shaped back splat (the centre upright of the chairback). The three sections are mortised into the yoke-like top rail. Despite that the innovation of this back splat exercised an influence on English chairs during the Queen Anne period, wooden items that just to a limited capability embolden corner joints (and furthermore were loose in the result) signify a feature signatory to Chinese chairs. The four legs sit through the seat frame, which stops upon the rounded staves. All members are round in section or has rounded edges—referable maybe to the bamboo tradition. The seat is not comfortable and had on occasion a plaited bottom. These chairs required of the sitter to hold themselves stiff and upright; if too much weight is pushed on the back, the chair has a habit of collapsing. In patriarchal Chinese homes of this period armchairs likely were reserved for older family members, for they were given great esteem.

The Chinese folding stool is believed to have been brought to China from the West. It is not dissimilar very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is prettily joined to the two legs of the stool by a curved member, which is usually seen with metal mounts. From a Western viewpoint the overall effect of these furniture styles is stylized. The constructive and aesthetic aspects are combined in a way that is at the same time naïve and refined. The patched up 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 with one another and fixed in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its signature on the chair. Paintings show a design of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between, stitched to bring up a pattern of little pads. The front board and a related board in the back could be folded after loosening some small iron hooks. Therefore the chair was an easily portable piece of furniture while traveling which, in the same period, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be found in engravings of interiors of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the design actually was instigated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was produced in impressive amounts, as can be seen from one of Abraham Bosse’s engravings, in which an entire row of these chairs lined up by a wall. The style asserts itself by its elegant 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 form—that is to say, as progressed in Paris around 1750—spread over most of Europe and was imitated or copied during the mid-20th century. The style owes such popularity to a combination of leisure and elegance. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions made between seat frame, legs, and back cover all the joints, which are strongly constructed on craftsmanlike methods even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of relatively thick dimensions; but all the members are deeply molded, all extra wood has been cut away, and more upmarket designs would be further embellished with very delicate and decorative carving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is generally used for all upholstery on the seat, back, and armrests; canework is sometimes used rather than upholstery.

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

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

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

What is Bookkeeping?

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping creates the information from which accounts are prepared but is a different process, prerequisite to accounting.

Essentially, bookkeeping records two types of information: (1) the current value, or equity, of the entity and (2) the change in value—profit or loss—taking place in the enterprise over a single period.

Management officials, investors, and credit grantors all need this kind of information: management so as to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to interpret the results of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an entity in deciding whether to give a loan.

Traces of financial and numerical record charts have been uncovered for nearly every nation with a commercial backbone. Records of business contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The double-entry way of bookkeeping came up with the progression of the entrepeneurial republics of Italy, and manuals for bookkeeping were created during the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial records a paramount factor. The past of bookkeeping, in fact, reflects the ancestry of commerce, industry, and government and, partially, helped to form it. The international spread of industrial and commercial activity demanded better sophisticate decision-making processes, which itself required better sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government regulation became more detailed and resulted in increased need for information; enterprising firms had to have information available to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the demand for bookkeeping for their inner departmental operations became larger.

Though bookkeeping procedures can be very multifaceted, all of it is based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and such), 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 prepared from the trial balance posted out of the ledger. The purpose of the income statement or profit-and-loss statement is to show an analysis of any changes that have taken place in the business equity due to the operations of the period. The balance sheet shows the financial position of the company at the particular date taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.

Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.

Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.

But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).

During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.

North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields 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.
