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

The typical question asked when looking for a new projector for the home, office, or classroom is: would I purchase an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different models available, it can be confusing for clients to decide between the two technologies. It comes down to the fact that LCD projectors give far better image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up a comparable rate of image quality.

Visualise a set of blinds in your home over your bedroom window. By pulling a rod you can turn the shutters open or closed, according to if you want to let light in or not. And that is exactly how an LCD projector works. Each pixel operates like an individual shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as 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 when the projector is turned on to when the image reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by cutting it into red, blue and green components, by three mirrors which direct the coloured light to 3 different LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. A point to realise about LCD projectors is that all three colours are sent onto your wall at the same time. The way a DLP projector operates is vastly different and even the produced image looks is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image requires a sequence of red, blue and green light. The millions of micro mirrors described 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 vision will then draw each coloured element of the image into a single whole image. Using LCD projectors, all colours are available all the time to deliver the top level of brightness and great colour accuracy. In DLP, just one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some manufacturers have included a white segment in the colour wheel to improve all over brightness, but this then detracts from colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and thus must be better quality. 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 technology is capable of producing. DLP projectors do offer high contrast specifications as compared to most LCD projectors. Initially, this can seem to be an advantage, however, in real life, the true black level is determined by the ambient light in the room while the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you want to view includes moving images, DLP projection technology also has image marks, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because every colour is sent simultaneously. DLP designers have come up with 3DLP solutions using 3 chips to resolve the colour break up issue, but the cost of these projectors make them hardly practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and recall how the various colours of light refract differing amounts when projected 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 not the same and refract light at different levels. Usually with a DLP projector, a spill of yellow colour will show above and a superfluous blue will come up below something as simple as a single black line. During manufacturing LCD projectors can be set to remove these effects on the projected image, as each colour is directed on its own LCD panels.

The isolated veritable plus (excluding price) with buying a DLP projector is its smaller total size and weight. However, this is only relevant for mobility and cannot be traded off against the image superiority of LCD projectors. If resulting picture quality is important to you, then the solution is easy. Go for an LCD projector! LCD projectors will always produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the first yacht had been a leisure craft used mostly by royalty and secondly by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting was found to be popular with the rich and nobility, but after that point the habit did not last.

The first yacht group in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, with great naval panoply and formality. The closest thing to racing boats was the “chase,” in which the “fleet” pursued an imaginary enemy. The club persisted, mostly as a social club, until 1765, and in 1828, by conglomerating with other societies, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered manner 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 sovereignty in 1820, it came to be named 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 formed 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 yacht racing. The association at Cowes became the Royal Yachting Club, again at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing races for great bids were held, and the club life was splendid. Ultimately Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English took power. Sailing was largely for fun and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a benchmark of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early 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 bigger yachts was first greatly impacted by the victory of America, which was drawn by George Steers for a syndicate led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. Earlier yachts were not designed and crafted 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 into being. Not until the 1920s did the employment of the study of aerodynamics do for the structure of sails and rigging what science had earlier done for hulls.

Because almost all sailboats were individually custom-built, there arose a requirement for handicapping boats before the one-design class boats were built. Hence, a rating rule was decreed, which is found in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the rapidly growing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to single 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 had on an even par with no handicapping at all. A great example is the standard International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

For the time that yachting belonged largely for the royal and the wealthy, expense was no problem, and the size of boats increased, in both length and weight. The promotion and popularity of smaller craft happened in the latter half of the 19th century in 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 hardiness of small craft. Thereafter in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts 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 setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam began to replace sail power in public vessels, the steam engine, and later the internal-combustion engine, were employed more and more in pleasure craft. Sizeable power yachts were developed to a high degree, and long-distance cruising turned into a preferred activity of the rich. The early power yachts were paddle-wheel boats; those then made way to those powered by the fully submerged screw or propeller sort of propulsion. Like naval and merchant vessels, auxiliaries carrying both sail and power were the yacht standard for many years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were solely power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of more sizeable steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of at least 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 saw active service in World War II.

As bigger and more dependable internal-combustion engines were created, many big craft were using them for power. The creation of the diesel engine, employing heavy oil for fuel, advanced from World War I. During the decade following that, bigger power-yacht manufacture grew, hitting a climax in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power craft fell away after 1932, and the style from then was for smaller, less expensive craft. After World War II, many small naval vessels were traded by private owners for conversion to yachts. By the late 20th century, yachting has become a internationally beloved competition enjoyed by thousands of yachtsmen who are actually owning and upkeeping their own small pleasure yachts. The amount of boats and owners has increased steadily, not only in the traditional locations on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the distribution of income and wealth. A proportional tax is one that places the same relative burden on all the taxpayers—i.e., in the case where tax liability and income grow in equal levels. A progressive tax is recognised by a more than proportional rise in the tax onus relative to the growth in income, and a regressive tax is recognised by a less than proportional growth in the related onus. So, progressive taxes are thought of as fighting a lack of equality in income distribution, whereas regressive taxes are believed to cause an increase in these inequalities.

The taxes that are normally believed to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, could become less so for the upper-income categories—especially if a taxpayer is allowed to reduce his tax base by declaring deductions or by leaving out some particular income elements from his taxable income. Proportional tax rates which are applied to lower-income demographics would also be more progressive if such personal exemptions are declared.

Income measured over the course of a given year does not absolutely offer the most appropriate measure of taxpaying status. For example, transitory rises in income can be saved, and in temporary declines in income a taxpayer may decide to provide for consumption by decreasing savings. Thus, if taxation is regarded along with “permanent income,” it would be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (save luxuries) tend to be regressive, because the dissemination of one’s income consumed or spent on a specific good declines as the amount of personal income grows. Poll taxes (aka head taxes), calculated as a flat amount per capita, clearly are regressive.

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

In assessing the economic effect of taxation, it is essential to differentiate between varied points of tax rates. The statutory rates are nominated in legislature; generally these are marginal rates, but for some cases 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. Ergo, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws generally contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates should regard provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated within 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 appropriate ones for appraising incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applicable to income from business and capital, because it may depend on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the part of total income that is taken in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly grow with income, both because personal allowances are provided 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 can dampen these effects, allowing regressivity, as displayed by average tax rates that decline as income rises.

The Development of Data Projectors

The LCDs put in projection systems are usually small reflective or transmissive panels illuminated by a strong arc lamp source. A series of lenses expands the reflected or transmitted image and casts it on the screen. For front-projection systems the LCD is placed on the same area of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of higher expense and capability might be found with three distinct LCD panels, creating separate red, green, and blue images that combine to make a coloured image on the screen.

The increasing desire for film presentations has placed a particular emphasis on the switching speed of liquid crystals. This has led to the invention of items employing smectic liquid crystals, particular types of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. In it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and throughout the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible consequence of the optical activity and the shape of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. Thus, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up 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 by doing so reverse the tilt direction of the molecules. The resultant change in optical properties can make a change from light to dark when one or more polarizers are used.

SSFLC devices have been commercialized for big passive-matrix displays, but their high cost and detail has hindered them from having any particular progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show 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 expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid pulsing (approximately 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods but then to a nontransmissive state for the blue period, creating the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture objects, the chair might be primary. While most other items (apart from the bed) are intended to support objects, the chair supports a human form. The term chair can be viewed here in the common sense, from stool to throne to further makes including the bench or sofa, which can be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinuishable.

The social history of the chair is as stimulating as its history as art and craft. The chair is not only a physical support or an aesthetic item; it historically is symbolic of social placement. Within the old royal courts there were significant signifiers between sitting on a chair with arms, or a chair with a back but without arms, or worse having to utilise a stool. In the past century, a director’s and manager’s chair has been seen as an identifier of superior status, as well as in democratic government debate the speaker sits on a higher level.

As a furniture form, the chair can be utilised for a range of various purposes. There are chairs structured to match man’s age and physical condition (the high chair, the wheelchair) and for his position in society (the executive chair, the throne). In past days there were chairs used for birth (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). We design chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has derived new chairs in automobiles and aircraft. Each of these chair kinds has changed to fit to evolving human desires. Because of its unique connection with man, the chair exists to its full advantage only when utilised. Although it is not relevant to one’s appreciation of a cupboard or a chest of drawers whether there is anything inside or not, a chair is understood best and fairly regarded by a person sitting on it, because chair and sitter complement each other. Thus the individual areas of a chair were labeled corresponding to the elements of a human shape: arms, legs, feet, back, and seat.

Because the obvious role of a chair is to support your body, its credit is tested principally by how suitably it fulfills this practical purpose. In the build of the chair, the maker is limited within certain static regulations and principal measurements. In these regulations, however, the chair builder has extensive freedom.

The history of the chair extended over an epoch of several thousand years. There are societies that had distinctive chair forms, expressive of the principal endeavour in the spheres of handling and art. In these such peoples, a 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 objects of skilled scheme, are now known from tomb discoveries. The first of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have had four legs designed not unlike those of a chosen animal, a curved seat, with a sloping back supported over vertical stretchers. From this design a durable triangular structure was obtained. There was from our view no marked variation between the creation of Egyptian thrones and chairs for typical people. The only difference lies in the intricacy of ornamentation, in the selection of pricier inlays. The Egyptian folding stool most likely was developed as an easily carried seat for army soldiers. As a camp stool the form existed until much later periods. But the stool also existed in the purpose of a ceremonial seat, its technical task as a folding stool neglected or forgotten. This can from evidence be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but aren’t able to be folded as the seats are made out of wood. The easy construction of the folding stool, consisting of two frames that turn on metal bolts and support a seat of leather or fabric secured between them, then came again somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of those is the folding stool, of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not in any ancient object still around but in a large amount of pictorial objects. The archetype is the klismos placed on the Hegeso Stele at the Dipylon burial place outside Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those are displayed. These creative legs were presumed to have been crafted of bent wood and were probably subjected to huge pressure from the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very solid and were plainly indicated.

The Romans borrowed from the Greek designs; some statues of seated Romans are chairs of a denser and apparently slightly more crudely constructed klismos. Both kinds, light and heavy, were popularised in the Classicist era. The klismos design can be evidenced in French Empire design, in English Regency, and in particular forms of notable individuality of Denmark and Sweden during 1800.

China
The progression of the chair in China cannot be traced as long as the progression of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unbroken serial of sketches and paintings has been preserved, detailing the insides and outside of Chinese homes and the designs of furniture. Another preservation of the 16th century are a trove of chairs made from wood or lacquered wood, that possess an amazing similarity to representations of older chairs.

As was the case in Egypt, there existed two standard chair forms in China: a chair having four legs and a folding stool. This chair is designed both with or without arms however always with its square seat and straight stiles (vertical side supports) to give support to the back. In one image, it must be said, the stiles had been lightly curved on top of the arms so as to suit the angle of the S-shaped back splat (the main upright of its back). Together, the three limbs were mortised onto the yoke-like top rail. Despite that the style of this back splat exercised an introduction for English chairs during the Queen Anne period, wooden items that would only to a restricted ability support corner joints (as well as being loose to top that off) indicate a design signatory to Chinese chairs. The four legs are set through the seat frame, which finishes about the rounded staves. Members are round in section or have rounded edges—acknowledging maybe to the bamboo tradition. The seat is uncomfortable and may have had a plaited texture. These chairs demanded of the sitter to stay stiff and upright; when too much weight is pushed on the back, the chair has a habit of collapsing. In patriarchal Chinese homes of this era armchairs presumably were allowed only for senior people in the family, for they were held in great esteem.

The Chinese folding stool is believed to have taken to China from the West. It does not vary that much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is delicately fixed to the two legs of the stool in a curved member, which is usually designed with metal mounts. From a Western point of view the ultimate effect of both of these furniture styles is stylized. The constructive and decorative issues are combined in a style that is at the same time naïve and refined. The patchwork appearance is an outcome of the manner that the individual parts do not look to have been fixed together by means of either glue or screws, but were mortised on one another and held in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its mark on the chair. Paintings show a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to bring out a pattern of little pads. The front board and a similar board from the back could be folded after loosening some small iron hooks. In this way the chair was an easily portable piece of furniture when traveling which, in the same period, gave the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is found in engravings of the interior of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not held that the design actually originated in The Netherlands. Typically, the legs of the chair are smooth, round in section, and of slender measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in impressive amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up along a wall. The form asserts itself by virtue of its harmonious proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that is to say, as brought out in Paris around 1750—conquered most of Europe and was imitated or copied into the mid-20th century. The design owes this popularity to a combination of relaxation and elegance. The seat adheres to the human body and permits a relaxed seated 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 are made between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of rather thick density; but all the members are deeply molded, all superfluous wood has been removed, and more expensive designs can be further embellished with highly delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all the upholstery on the seat, back, and armrests; cane is in some cases used rather than upholstery.

English chairs in the 18th century were more differentiated in design than the French. The French taste for stylistic uniformity, which disseminated from the most distinguished circles in Paris and Versailles through 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 reknowned and was widely distributed throughout the world.

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

In cheaper brands 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, hint that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping creates the figures from which accounts are written but is a previous process, required prior to accounting.

Essentially, bookkeeping provides two areas of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking position in the business within a particular time.

Management officials, investors, and credit grantors all need such information: management to interpret the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to assess the results of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to analyze the financial statements of an enterprise in finding whether to allow a loan.

Evidence of financial and numerical charts are seen for just about every state with a commercial history. Records of business contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been archived in ancient Greece and Rome. The dual-entry style of bookkeeping came with the furthering of the business republics of Italy, and tutorial books for bookkeeping were created in the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a must-have. The ancestry of bookkeeping, in fact, closely reflects the ancestry of commerce, industry, and government and, in part, helped shaping it. The worldwide expansion of industrial and commercial activity required greater sophisticate decision-making procedures, which then needed greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislature became more significant and resulted in greater requirement for information; business entities 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 become larger, and the need for bookkeeping for their inner departmental operations went up.

Although bookkeeping methodology can be extremely detailed, it is all based on two kinds of books employed in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so forth), and the ledger contains the record of individual accounts. The daily records kept in the journals are entered in the ledgers.

Every month, generally speaking, an income statement and a balance sheet are constructed from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to provide an analysis of those changes that have taken place in the enterprise equity as a result of the operations of the period. The balance sheet shows the financial situation of the entity at any particular day regarding assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields resulted in an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

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

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

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

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

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