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

The most typical question customers ask when looking for a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and different models available, it can be challenging for consumers to choose between those technologies. The simple fact of the matter is that LCD projectors offer far better image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with creating a comparable grade of image quality.

It’s like a set of blinds in your home on your bedroom window. By twisting a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. This is exactly how an LCD projector functions. Each pixel functions like a unique shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector is switched on to when the picture reaches your screen is extremely significant with regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by splitting it into red, blue and green components, by three mirrors which send the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by turning each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. A significant point to remember about LCD projectors is that all three colours are directed onto your projector screen simultaneously. The way a DLP projector operates is totally different and even how an image shows up 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 method of projecting an image requires 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 cast 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 complete image. In LCD projectors, all colours are available all the time to offer the best brightness and great colour accuracy. In DLP, only one colour is available at a time, causing lower colour brightness and accuracy. Some designers have added a white segment for the colour wheel to improve overall brightness, but this further damages colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and as such must be superior quality. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is able to produce. DLP projectors do offer high contrast specifications compared to a majority of LCD projectors. At a glance, this can seem to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room in which the projector is in use. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to project requires moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are displayed. LCD projectors do not have this problem because every colour is projected with the others. DLP builders have developed 3DLP solutions using 3 chips to answer the colour break up artifacts, but the expense of these projectors make them hardly practical for most businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how the different colours of light refract differing amounts when directed through the same lens. The downside with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light at different levels. Generally with a DLP projector, some extra yellow colour will appear above and a spill of blue will be projected below an image containing something as simple as a single black line. While being built LCD projectors can be fixed to reduce these effects on the projected image, as each colour is projected on its own LCD panels.

The sole veritable advantage (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 superiority of LCD projectors. If the result of the picture quality is vital to you, then the solution is no-brainer. Go with an LCD projector! LCD projectors will consistently 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 initial yacht had been a leisure craft used initially by royalty and later by the burghers in the canals as well as 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 return to the English monarchy 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, reigned 1685–88), made more 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 was found to be fashionable with the affluent and royalty, but after that period the habit did not last.

The first yacht association in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had great naval panoply and rigour. The closest thing to a race was the “chase,” in which the “fleet” pursued an imagined enemy. The club endured, largely as a social club, until 1765, and in 1828, after joining with other clubs, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered fashion on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British yacht racing. The organisation at Cowes became the Royal Yachting Club, again at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing races for large bids were held, and the club life was splendid. Eventually Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was for the most part for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a benchmark of luxury and sophistication for the later yachts in those waters from the late 19th century. The first continuing American yacht society, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The craft of bigger yachts was initially heavily put upon by the victory of America, which was designed by George Steers for a group headed 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. The first yachts were not designed and manufactured in today’s sense, with only a model 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 science of aerodynamics do for the structure of sails and rigging what such study had done earlier for hulls.

Because almost all sailboats were individually manufactured, there was a need for handicapping boats as this was before the one-design class boats were made. Therefore, a rating rule was created, which ended up in the International Rule, adopted in 1906 and revised in 1919. In modern times, one of the most rapidly growing areas in 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 elements (for an example of a two-person sailboat, see illustration). Racing for those boats can be done on an even par with no handicapping at all. A perfect example is the standard International America’s Cup Class adopted for participants in the 1992 America’s Cup race.

So long as yachting belonged largely for the nobility and the wealthy, cost was no issue, and the size of boats increased, in both length and weight. The promotion and desire of smaller craft came in the latter half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of smaller boats. Following this in the 20th century, notably after World War II, smaller racing and recreational boats became more popular, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, at which point steam was set to replace sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure yachts. Large power yachts were furthered to a high degree, and long-distance cruising became a preferred occupation of the affluent. The first power yachts were paddle-wheel boats; those then made way to those powered by the fully submerged screw or propeller kind of propulsion. As in the case of naval and merchant craft, auxiliaries carrying both sail and power were the yacht standard for many years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of bigger steam yachts. Conspicuous of these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 150. The Mayflower, 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 during World War II.

As bigger and more dependable internal-combustion engines were created, many bigger yachts were using them for power. The development of the diesel engine, with heavy oil for fuel, was furthered for World War I. From the decade after, large power-yacht manufacture flourished, hitting a climax in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power craft lessened from 1932, and the trend after that was for smaller, less costly craft. After World War II, a lot of small naval vessels were bought by private owners for conversion to yachts. In the late 20th century, yachting is a internationally loved sport enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small recreational craft. The number of yachts and sailors increased steadily, not only in the traditional areas on the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the effect they have on the distribution of income and wealth. A proportional tax is a tax that applies the same relative liability on each taxpayer—i.e., when tax liability and income move in equal levels. A progressive tax is characterized by a greater than proportional rise in the tax onus relative to the increase in income, and a regressive tax is characterizable by a less than proportional rise in the comparative liability. So, progressive taxes are viewed as fighting inequalities in income distribution, but regressive taxes can result in increasing these inequalities.

The taxes that are normally thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so in the upper-income demographic—especially if a taxpayer is allowed to lessen his tax base by declaring deductions or by removing particular income parts from his taxable income. Proportional tax rates that are applied to lower-income groups will also be more progressive if exemptions of a personal nature are claimed.

Income measured over the course of a given period may not absolutely offer the best measure of taxpaying requirements. For example, transitory growth in income may be saved, and during temporary declines in income a taxpayer might decide to pay for consumption by decreasing savings. Ergo, if taxation is held in comparison along with “permanent income,” it will be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (with the exception of those on luxuries) tend to be regressive, because the spread of own income consumed or spent on specific goods declines as the rate of personal income rises. Poll taxes (aka head taxes), levied as a flat amount per capita, obviously are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden depends essentially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In analysing the economic purpose of taxation, it is relevant to differentiate between varied ideas of tax rates. The statutory rates will be specified in the law; usually these are marginal rates, but in some cases they are average rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income grows by one dollar. So, if tax liability increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that grow as income increases. Structured analysis of marginal tax rates are required to regard provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more 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 appropriate ones for assessing incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, because it may be reliant on considerations 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 nil under a consumption-based tax.

Average income tax rates determine the percentage of total income that is demanded 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 rises with income. Average income tax rates generally rise with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households might dwarf these effects, allowing regressivity, as displayed by average tax rates that fall as income rises.

The Development of Data Projectors

The LCDs put in projection systems are typically small reflective or transmissive panels lit up by a strong arc lamp source. A series of lenses expands the reflected or transmitted image then casts it on a screen. For front-projection systems the LCD is set on the side of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of more expense and performance sometimes be found with three separate LCD panels, casting separate red, green, and blue images that come together to reflect a coloured display on the screen.

The increase in requirement for visual displays has granted a special emphasis on the switching speed of liquid crystals. This has demanded the manufacture of items employing smectic liquid crystals, some types of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. Within it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are tilted, as demonstrated in the figure. The host liquid crystal has optically active molecules, and a scarcely perceptible consequence of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. Thus, there exists a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been marketed for bigger passive-matrix presentations, but their expense and complexity has hindered them from enjoying any significant effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are removed for a coloured backlight that flashes red, green, and blue in quick speed (approximately 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods but to a nontransmissive state in 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 items, the chair might be the paramount one. While most of the other pieces (apart from the bed) are created to support objects, the chair supports the human form. The term chair must be looked upon here in the most open sense, from stool to throne to further forms such as a bench and sofa, which might be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously definitive.

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/or aesthetic object; it is historically symbolic of social standing. Within the Medieval royal courts there were plain distinctions between possessing a chair with arms, on a chair with a back but no arms, and having to squat on a stool. From the recent century, the director’s and/or manager’s chair has developed a signifier of superior dignity, as well as in democratic government meeting the speaker sits on a higher level.

In a furniture creation, the chair is utilised for a range of various makes. There are chairs manufactured to fit man’s age and physical abilities (the high chair, the wheelchair) and to show his position in society (the executive chair, the throne). From the past there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs used for ending life (the electric chair). There are chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our modern lifestyle has derived particular chairs for use in automobiles and aircraft. Every one of these chair forms has been evolved to match to changing human desires. Due to its close importance with man, the chair comes to its full meaning only when being utilised. Although it does not make a difference to one’s appreciation of a cupboard or a bureau whether there might be items inside or not, a chair is really seen best and judged with a person sitting on it, because chair and sitter need the other. Thus the individual areas of the chair were given names like the limbs of a human parts: arms, legs, feet, back, and seat.

Because the first purpose of the chair is to support a body, its worth is judged firstly from how fully it fulfills this practical role. In the creation of a chair, the designer is limited with the static rules and principal measurements. Through these restrictions, however, the chair creator has large freedom.

The history of the chair extended over dates of several thousand years. There existed civilizations that made significant chair types, expressive of the principal endeavour in the arenas of technique and aesthetics. Within those civilisations, individual 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of skilled craft, were a finding from discoveries made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs crafted as akin to those of some animal, a curved seat, and leading to a sloping back supported by vertical stretchers. In this way a durable triangular construction was made. There seems to be no particular differentiation in the construction of Egyptian thrones and chairs for common populace. The real difference existed in the complex ornamentation, in the choice of more costly inlays. The Egyptian folding stool in all probability was made as an easily portable seat for officers. As a camp stool this stool stayed around for much later periods of time. But the stool then was made as the use of a ceremonial seat, its original job as a folding stool simply forgotten. This can from today be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are made in the form of folding stools but can’t be folded because the seats were made from wood. The simple structure of the folding stool, composed of two frames that rotate on metal bolts and support a seat of leather or fabric set between them, then appeared but somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this type is the folding stool, from ashwood, found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not with any ancient specimen still existing but as found in a wealth of pictorial items. The significant kind is the klismos depicted on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of them would be displayed. These curving legs were understood to be executed in bent wood and were in that case had to bear extreme pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat were therefore super solid and were visibly denoted.

The Romans adopted the Greek chair; some models of seated Romans show designs of a thicker and in appearance rather more crudely designed klismos. Both features, the light and the heavy, were popularised within the Classicist era. The klismos chair is evidenced in French Empire styles, in English Regency, and in some particular types of marked iconicism in Denmark and Sweden during 1800.

China
The history of the chair in China can not be charted as long as the history of chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken collection of drawings and paintings had been protected, displaying the insides and outside of Chinese buildings and the designs of furniture. Another preservation from the 16th century are a collection of chairs constructed of wood or lacquered wood, that show an amazing familiarity to styles of previous chairs.

Just the same as in Egypt, there were two iconic chair designs in China: a chair that had four legs and a folding stool. That four-legged chair is designed both with or without arms but never without its square seat and straight stiles (vertical side supports) to support the back. In one style, it must be said, the stiles were lightly curved on top of the arms to sit right with the form of the S-shaped back splat (the centre upright of its chairback). Together, all three limbs had been mortised on the yoke-like top rail. Although the innovation of a back splat later had a foundation for English chairs during the Queen Anne period, wooden members that could merely to a restricted ability stabilise corner joints (and then were loose as a result) signify an element particular to Chinese chairs. The four legs pass through the seat frame, which closes about the rounded staves. Members are round in section or has rounded edges—acknowledging maybe to the bamboo tradition. The seat is unpleasant to sit in and might have had a plaited bottom. These chairs needed the sitter to be stiff and upright; for if too much pressure is pushed on the back, the chair has a tendency to fall. In patriarchal Chinese houses of this era armchairs probably were kept for elderly family members, for they were given great esteem.

The Chinese folding stool is presumed to have been brought to China from the West. It is not dissimilar much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is elegantly held to the two legs of the stool by a curved member, which is often possessing metal mounts. From a Western point of view the resultant effect of both furniture styles is stylized. The construction and decoration aspects are combined in a way that is all at once naïve and refined. The piecemeal appearance is a result of the manner that the individual parts do not seem to have been fixed together by use of either glue or screws, but have been mortised with one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its mark on the chair. Works of art show a kind of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to bring out a pattern of little pads. The front board and a related board at the back could be folded after loosening some little iron hooks. Therefore the chair was a portable piece of furniture for traveling which, during the same time, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be found in engravings of the interior of affluent Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair can also be found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not determined that the design actually originated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of thin dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was manufactured in considerable numbers, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up by a wall. The design asserts itself by virtue of its shapely proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that is to say, as created in Paris around 1750—disseminated through most of Europe and has been imitated or copied during the mid-20th century. The style owes this popularity to a combination of comfort and delicacy. The seat conforms to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are strongly constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those use wood of quite thick density; but all the members are deeply molded, all extra wood has been cut away, and finer designs would be further embellished with very delicate and decorative woodwork. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all the upholstery on the seat, back, and armrests; cane is occasionally used instead of upholstery.

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

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

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

In cheaper versions of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the transactions of a business. Bookkeeping grants the numbers from which accounts are prepared but is a different process, prior to accounting.

Predominantly, bookkeeping records two types of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking place in the entity during a single time period.

Management officials, investors, and credit grantors all need to have this kind of information: management so as to understand the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to interpret the outcomes of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to analyze the financial statements of an entity in judging whether to grant a loan.

Traces of financial and numerical charts have been uncovered for nearly every state with a commercial backbone. Records of business contracts were uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The dual-entry way of bookkeeping came up with the progression of the business republics of Italy, and tutorials for bookkeeping were produced during the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial bookkeeping a necessity. The past of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, in some part, helped in shaping it. The global revolution of industrial and commercial activity demanded greater sophisticate decision-making procedures, which in its turn needed more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government regulation became more important and resulted in higher requirement for information; firms had to show information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for their own inner operations became larger.

Though bookkeeping methods can be extremely complex, all of it is based on two kinds of books used in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger contains the records of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, as a general rule, 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 present an analysis of those changes that took place in the business equity because of the events of the period. The balance sheet displays the financial situation of the enterprise at a particular point taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

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

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

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

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