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

The typical question heard when purchasing a new projector for the home, office, or classroom is: would 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 different brands and models available, it can be confusing for clients to choose between these technologies. The simple fact of the matter is that LCD projectors provide far superior image quality and colour accuracy. The next paragraph tells you why DLP projectors struggle with bringing up an equal level of image quality.

Think of a set of blinds in your home on your bedroom window. By pulling a rod you can make the shutters open or closed, depending on if you want to let light in or not. And that is exactly how an LCD projector behaves. Each pixel works like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element functions 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 absolutely important for image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by cutting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by processing each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. An important point to realise about LCD projectors is that all three colours are projected onto your screen all at the same time. The way a DLP projector operates is widely different and even the way an image comes out is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to creating an image creates a sequence of red, blue and green light. The millions of micro mirrors as 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 eyes will then combine each coloured element of the image into the single full image. With LCD projectors, all colours are available all the time to create the highest brightness and spectacular colour accuracy. In DLP, just one colour is available at once, causing lower colour brightness and accuracy. Some DLP developers have included a white segment into the colour wheel to improve brightness overall, but this further lessens colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and ergo must be better quality. For those uncertain, 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 able to produce. DLP projectors do provide high contrast specifications compared to the majority of LCD projectors. At one glance, this can seem to be a plus, however, in reality, the true black level is determined by the ambient light in the room while the projector is used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you plan to see includes moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most common artifact that a DLP projector creates with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are projected. LCD projectors do not have this downside because all the colours are sent with the others. DLP builders have developed 3DLP solutions using 3 chips to resolve the colour break up problem, but the price tag of these projectors make them hardly practical for the majority of businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Remember back to high school science, and recall how various colours of light refract varied amounts when projected through the same lens. The downfall with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Usually with a DLP projector, some extra yellow colour will come through above and a spill of blue will come up below an image containing something as simple as a lone black line. In building LCD projectors can be adjusted to remove these effects on the projected image, as each colour is directed on its own LCD panels.

The one actual buy point (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant with regard to portability and must be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is crucial to you, then the choice is simple. Choose an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the first yacht was a leisure craft used initially by royalty and later by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private games. English yachting began with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy 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 named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), ordered for 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 rose as popular among the wealthy and nobility, but after that period the trend did not last.

The first yacht group in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, with large naval panoply and formality. The closest thing to racing boats was the “chase,” in which the “fleet” pursued a fictional enemy. The club went on, largely as a social club, until 1765, and in 1828, after joining with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered manner on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yachting. The society at Cowes became the Royal Yachting Club, also at the rise of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing matches for large bets were held, and the society life was splendid. Ultimately Royal Yachting Club boats were raised in size to more than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English held power. Sailing was largely for pleasure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a minimum of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard 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 to the latter half of the 19th century. The style of bigger yachts was initially heavily impacted by the win 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.) was named after its success at Cowes in 1851. The first yachts were not designed and manufactured in a contemporary sense, with only a model for an outline. Not until the later half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the application of the research of aerodynamics do for the craft of sails and rigging what science had already done for hulls.

Because almost all sailboats were individually manufactured, there was a desire for handicapping boats before the one-design class boats were made. Thus, a rating rule was decreed, which ended up in the International Rule, taken on in 1906 and amended in 1919. Today, 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 manufactured to the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for these boats can be done on an even playing field with no handicapping necessary. A great example is the generic International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

So long as yachting was done largely for the aristocracy and the wealthy, expense was no issue, and the size of boats developed, in both length and weight. The promotion and popularity of smaller craft happened in the second 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 trip around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of small yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and recreational yachts became more common, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, during which steam started to emulate sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly employed in leisure craft. Large power yachts were progressed to a high element, and long-distance travel was a fond occupation of the wealthy. The first power yachts were paddle-wheel boats; they then made way to yachts powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant boats, auxiliaries with both sail and power were the yacht standard for several years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the large part were exclusively power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of bigger 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, commissioned 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 more sizeable and more dependable internal-combustion engines were developed, many big craft were using them for power. The establishment of the diesel engine, with heavy oil for fuel, progressed for World War I. During the decade after, large power-yacht creation blossomed, 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 manufacture of large power boats declined from 1932, and the style after that was in preference of smaller, less costly craft. From World War II, lots of small naval boats were traded by private owners for conversion to yachts. At the late 20th century, yachting is a widespread popular competition enjoyed by thousands of yachtsmen personally sailing and keeping their own small pleasure craft. The popularity of boats and sailors has increased steadily, not only in the traditional places on the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that imposes the same relative onus on all taxpayers—i.e., in the case where tax liability and income increase in equal scale. A progressive tax is recognised by a more than proportional increase in the tax burden in regard to the increase in income, and a regressive tax is recognisable by a less than proportional rise in the related onus. So, progressive taxes are thought of as fighting inequalities in income distribution, whereas regressive taxes can cause an increase in these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, might become less so within the upper-income demographic—especially if a taxpayer is permitted to reduce his tax base by claiming deductions or by taking some particular income parts from his taxable income. Proportional tax rates which are applied to lower-income groups can also be more progressive if exemptions of a personal nature are claimed.

Income measured over a given year might not definitely give the best measure of taxpaying status. For example, transitory rises in income might be saved, and in temporary declines in income a taxpayer might elect to provide for consumption by reducing savings. So, if taxation is compared alongside “permanent income,” it will be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are mostly regressive, because the spread of individual income consumed or spent on specific goods declines as the level of personal income grows. Poll taxes (also called head taxes), calculated as a fixed amount per capita, patently are regressive.

It is hard to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden lays fundamentally on whether a national or a subnational (that is, provincial or state) tax is being determined.

In assessing the economic effect of taxation, it is essential to differentiate between differing concepts of tax rates. The statutory rates are those dictated in the law; commonly these are marginal rates, but in some cases they are average rates. Marginal income tax rates signify the fraction of incremental income that is taken by taxation when income increases by one dollar. So, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that rise as income increases. Heavy 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) falls by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified 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 necessary ones for assessing incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, as it may rely on considerations including 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 display the percentage of total income that is required in taxation. The pattern of average rates is the one that is in consideration for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually rise with income, both because personal allowances are granted for the taxpayer and dependents and also because marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households might swamp these effects, forcing regressivity, as signified by average tax rates that decline as income grows.

The Development of Data Projectors

The LCDs used for projection systems are generally small reflective or transmissive panels lit by a strong arc lamp source. A line of lenses magnifies the reflected or transmitted image then sends it on the screen. With front-projection systems the LCD is placed on the side of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of greater expense and capacity sometimes use three separate LCD panels, creating separate red, green, and blue images that blend to form a coloured display on the screen.

The increasing desire for pictographic presentations has placed a special emphasis on the switching speed of liquid crystals. This has required the invention of devices employing smectic liquid crystals, particular kinds of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most progressive smectic device. Inside it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are slanted, as shown in the figure. The host liquid crystal holds optically active molecules, and a minor result 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 in the plane of the layers. Therefore, there exists a permanent charge separation over 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 therefore reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been marketed for larger passive-matrix displays, but their cost and complexity has prevented them from having any remarkable impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate response allows them to be used in time-sequential colour systems, in which highly expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick succession (around 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods but then to a nontransmissive state in the blue period, creating the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture needs, the chair may be the paramount one. While most of the other pieces (apart from the bed) are meant to support objects, the chair supports the human form. The term chair is meant to be used here in the wider sense, from stool to throne to further chairs including a bench or sofa, which should be considered 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 interesting as its history as art and craft. The chair is not just a physical support and aesthetic piece of art; it can also be symbolic of social ranking. From the historical royal courts there were significant differences between being led to a chair with arms, or a chair with a back but no arms, or having to squat on a stool. During the recent century, the director’s or manager’s chair has risen an identifier of superior dignity, and even in democratic government meeting the speaker sits on a high-set level.

As its furniture purpose, the chair can be utilised for a range of different purposes. There are chairs manufactured to match man’s age and physical form (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). Since past times there were chairs for births (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 up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has demanded special chairs in automobiles and aircraft. All these chair kinds have changed to fit to growing human uses. Because of its particular link with man, the chair appears to its full advantage only when being utilised. Though it is irrelevant to one’s appreciation of a cupboard or a chest of drawers if there is anything inside or not, a chair is best seen and evaluated with a person using it, because chair and sitter need one another. Thus the different areas of the chair have been given labels according to the areas of a human body: arms, legs, feet, back, and seat.

Because the basic role of the chair is to support our human body, its value is judged firstly from how fully it does measure up to this practical use. Within the construction of a chair, the builder is limited for some static regulations and principal measurements. In these boundaries, however, the chair builder has great freedom.

The history of the chair lasted over an epoch of several thousand years. There were societies that had made individual chair types, as expressions of the leading object in the arenas of handling and aesthetics. Among such societies, special mention should 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 craft, are now a finding from findings made in tombs. The first of these two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have four legs designed like those of some animal, a curved seat, and with a sloping back supported by vertical stretchers. From this a solid triangular form was created. There was from our understanding no notable difference from the construction of Egyptian thrones and chairs for regular populace. The only difference was in the type of ornamentation, in the selection of more costly inlays. The Egyptian folding stool probably was designed for an easily portable seat for army soldiers. As a camp stool the form persevered til much later periods of time. But the stool also then was designed as the role of a ceremonial seat, its technical function as a folding stool being forgotten. This can now be found, 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 in the structure of folding stools but can’t be folded as the seats are created with wood. The simplistic make of the folding stool, made of two frames that spin on metal bolts and bear a seat of leather or fabric held between them, came up but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this type is the folding stool, made of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not from any ancient fossil still around but as seen from a large amount of pictorial objects. The best known is the klismos displayed on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs can be visible. These creative legs were presumed to have been crafted with bent wood and were thus bore great pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat would have had to be therefore super solid and were clearly pointed out.

The Romans borrowed from the Greek designs; quite a few casts of seated Romans are designs of a thicker and which appear to be a slightly crudely crafted klismos. Both styles, the light or the heavy, were popularised in the Classicist epoch. The klismos influence can be evidenced in French Empire furniture, in English Regency, and in particular kinds of profound originality within Denmark and Sweden around 1800.

China
The history of the chair in China isn’t able to be tracked as long as the progression of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) a full serial of drawings and artworks has been kept safe, showing the insides and exterior of Chinese homes and their furniture. Another preservation of the 16th century are a number of chairs made of wood or lacquered wood, that bear an amazing familiarity to designs of older chairs.

Just as in Egypt, two fundamental chair forms existed in China: a chair that had four legs and a folding stool. This chair has been constructed both with or without arms although never missing a square seat and straight stiles (standing side supports) to firm the back. In one design, it must be said, the stiles were delicately curved above the arms to fit the form of the S-shaped back splat (the basic upright of a chairback). Together, the three areas had been mortised onto the yoke-like top rail. Though the design of the Chinese back splat had an introduction for English chairs during the Queen Anne period, wooden members that could merely to a limited capability embolden corner joints (and furthermore are loose additionally) are an element signatory to Chinese chairs. The four legs sit through the seat frame, which ends around the rounded staves. All members are round in section or possesses rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is not comfortable and had on occasion a plaited bottom. These chairs needed the sitter to stay stiff and upright; if too much weight is exerted on the back, the chair has a way of falling over. In patriarchal Chinese houses of this era armchairs likely were kept for elderly people in the family, for they were greatly respected.

The Chinese folding stool is believed to have been brought to China from the West. It is akin that much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is prettily fixed to the two legs of the stool by a curved member, which is generally provided with metal mounts. From a Western viewpoint the ultimate effect of both of these furniture designs is stylized. The construction and decorative aspects are combined in a manner that is at the same time naïve and refined. The piecemeal appearance is an outcome of the manner that the individual members do not look to have been held together with either glue or screws, but are mortised with 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 signature on the chair. Artworks project a design of chair with a relatively crude wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of tiny pads. The front board and a similar board from the back could be folded after unscrewing some small iron hooks. In this way the chair was a readily portable piece of furniture in 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 is found in engravings of the inside of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair is also made in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not determined that the form actually was instigated in The Netherlands. Usually, the legs of the chair will be smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was made in large amounts, as can be surmised from one of Abraham Bosse’s engravings, in which an entire row of such chairs lined up along a wall. The form asserts itself by virtue of its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is, as created in Paris around 1750—disseminated over most of Europe and has been imitated or copied in the mid-20th century. The design owes its popularity to a combination of leisure and charm. The seat conforms to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are made between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of relatively thick measurements; but all the members are deeply molded, all superfluous wood has been cut away, and finer chairs would be further embellished with special delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; crosshatched cane is in some cases used as an alternative to upholstery.

English chairs in the 18th century were more differentiated in form than the French. The French touch for stylistic uniformity, which disseminated from the highest circles in Paris and Versailles throughout most of France and became the favourite 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 well-known and was widely distributed throughout the world.

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

In cheaper 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, 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 provides the details from which accounts are made but is a different process, preliminary to accounting.

Predominantly, bookkeeping grants two areas of information: (1) the current value, or equity, of an enterprise and (2) any changes in value—profit or loss—taking place in the entity from a single period.

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

Evidence of financial and numerical charts can be seen for nearly every society with a commercial history. Records of trading contracts have been discovered in the archaelogical digs of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The two-entry way of bookkeeping came with the development of the business republics of Italy, and tutorial manuals for bookkeeping were produced in the 15th century in many Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial books a requirement. The history of bookkeeping, in fact, closely reflects the ancestry of commerce, industry, and government and, in some part, assisted shaping it. The international spread of industrial and commercial activity needed more sophisticated decision-making processes, which then demanded higher sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government legislature became more detailed and resulted in increased demand for information; business firms had to show available information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the need for bookkeeping for their own inner operations increased.

Though bookkeeping methodology can be rather complex, all of it is based on two kinds of books employed in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and such), and the ledger should have the record of individual accounts. The daily records kept in the journals are written in the ledgers.

Every month, generally, an income statement and a balance sheet are created from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to display an analysis of any changes that happen in the business equity from the events of the period. The balance sheet gives the financial condition of the company at the particular date with regard to 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.
