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

The typical question heard when looking for a new projector for the home, office, or classroom is: will I purchase an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and types available, it can be challenging for consumers to make a choice between those technologies. Ultimately LCD projectors offer far better image quality and colour accuracy. The following article tells you why DLP projectors struggle with reproducing an equal grade of image quality.

Visualise a set of blinds in your home covering your bedroom window. By pulling on a rod you can turn the shutters open or closed, depending on whether you want to let light in or not. 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 made up of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from when the projector is turned on to when the content reaches your screen is vitally significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by shining each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. An important point to understad about LCD projectors is that all three colours are sent onto your projector screen simultaneously. The way a DLP projector runs is vastly different and even how an image appears 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 projecting 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 sent in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into the single complete image. Using LCD projectors, all colours are available all the time to form the highest brightness and great colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some DLP designers have put a white segment into the colour wheel to improve overall brightness, but this goes and degrades colour accuracy.

I find in forums all the time that DLP gives a higher contrast ratio and therefore must be better quality. For those unaware, 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 capable of producing. DLP projectors do offer high contrast specifications as compared to many LCD projectors. At a glance, this appears to be an advantage, however, in the real world, the true black level is determined by the ambient light in the room in which the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to view requires moving images, DLP projection technology can also create image imperfections, 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 projected. LCD projectors do not have this disadvantage because every colour is processed with the others. DLP builders have developed 3DLP solutions using 3 chips to fix the colour break up error, but the expense of these projectors make them hardly practical for many businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and recall how the various colours of light refract various amounts when directed through the same lens. The disadvantage 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 obviously not the same and refract light in a different way. Most of the time with a DLP projector, some yellow colour will come up above and some blue will come up below an image of something as simple as a single black line. While being built LCD projectors can be set to reduce these effects on the projected image, because each colour is projected on isolated LCD panels.

The isolated actual benefit (excluding price) with going with a DLP projector is its smaller total size and weight. However, this is only relevant to mobility and needs to be traded off against the image benefits of LCD projectors. If the outcome of the picture quality is crucial to you, then the solution is no-brainer. Go with an LCD projector! LCD projectors will constantly create bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the initial yacht became a leisure craft used mostly by royalty and then by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure 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), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting rose as classy among the affluent and royalty, but after that point the habit did not last.

The first yacht association in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, with much naval panoply and gravity. The closest thing to racing was the “chase,” in which the “fleet” pursued an imagined enemy. The club went on, largely as a social club, until 1765, and in 1828, when conglomerating with other groups, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered fashion on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it was called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been formed 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 perpetual location of British yacht racing. The organisation at Cowes became the Royal Yachting Club, again at the ascension of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing matches for high bids were held, and the club life was splendid. It came to be that the Royal Yachting Club boats were raised in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English gained 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 set a minimum of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was instigated 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 were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The design of bigger yachts was first heavily impacted by the victory of America, which was created by George Steers for a club headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. Earlier yachts were not designed and manufactured in today’s sense, with only a model being used. Not until the later half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the use of the study of aerodynamics do for the design of sails and rigging what science had previously done for hulls.

Because most of all sailboats had to be individually built, there came a need for handicapping boats as this was before the one-design class boats were designed. Thus, a rating rule was written, which resulted in the International Rule, accepted in 1906 and edited in 1919. In the present day, one of the rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are created to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even playing field with no handicapping required. A prime example is the standard International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

So long as yachting belonged largely for the aristocracy and the wealthy, cost was no object, and the size of boats developed, in both length and weight. The ascendancy and desire of smaller craft occurred in the later half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip 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 craft. Following this in the 20th century, particularly after World War II, smaller racing and pleasure yachts became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam started to take the place of sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure craft. Bigger power yachts were progressed to a high degree, and long-distance cruising was a preferred occupation of the well off. The early power yachts were paddle-wheel boats; those then made way to boats powered by the fully submerged screw or propeller kind of propulsion. As well as naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were solely power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of more sizeable steam yachts. Conspicuous among these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was operated 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 better quality internal-combustion engines were developed, many bigger yachts started using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed for World War I. From the decade after that, big power-yacht manufacture flourished, hitting a climax in the Orion (1930) at 3,097 tons. In that time the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power yachts fell away from 1932, and the trend after that was for smaller, less pricey yachts. After World War II, many small naval craft were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a widespread popular activity enjoyed by thousands of yachtsmen individually sailing and keeping their own small pleasure boats. The popularity of boats and sailors is increasing steadily, not only in the traditional places by the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the allocation of income and wealth. A proportional tax is the kind of tax that puts the same relative requirement on every taxpayer—i.e., where tax liability and income move in equal levels. A progressive tax is characterized by a larger than proportional growth in the tax liability in regard to the rise in income, and a regressive tax is characterized by a less than proportional increase in the comparable burden. So, progressive taxes are thought of as taking away the lack of equality in income distribution, while regressive taxes might cause an increase in these inequalities.

The taxes that are usually believed to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so within the upper-income class—particularly if a taxpayer is permitted to reduce his tax base by claiming deductions or by taking some certain income elements from his taxable income. Proportional tax rates when applied to lower-income groups can also be more progressive if exemptions of a personal nature are claimed.

Income measured over a given period does not necessarily give the most appropriate measure of taxpaying requirement. For example, transitory increases in income can be saved, and in temporary declines in income a taxpayer might choose to pay for consumption by reducing savings. Therefore, if taxation is made comparable alongside “permanent income,” it will be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are usually regressive, because the spread of personal income consumed or spent for a specific good lessens as the rate of personal income grows. Poll taxes (also known as head taxes), nominated as a flat amount per capita, patently are regressive.

It is hard to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the lack of certainty surrounding 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 debated.

In considering the economic effect of taxation, it is important to differentiate between several ideas of tax rates. The statutory rates will be nominated in the law; often these are marginal rates, but for some cases they are median rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income is increased by one dollar. Ergo, if tax onus increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes often contain graduated marginal rates—i.e., rates that grow as income grows. Heavy analysis of marginal tax rates must review provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points more than specified within the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applicable to income from business and capital, as 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 shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the portion of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates commonly rise with income, both because personal allowances are permitted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received predominantly by high-income households could dampen these effects, forcing regressivity, as shown by average tax rates that decline as income grows.

The Development of Data Projectors

The LCDs utilised in projection systems are most often small reflective or transmissive panels lit up by a strong arc lamp source. A series of lenses magnifies the reflected or transmitted image and then displays it onto a screen. With front-projection systems the LCD is placed on the side of the screen as the viewer, however in rear-projection systems the screen is lit from behind. Projectors of greater cost and capability sometimes have three separated LCD panels, reflecting separate red, green, and blue images that combine to create a coloured image on the screen.

The increasing need for video displays has placed a growth in emphasis on the switching speed of liquid crystals. This has required the development of objects employing smectic liquid crystals, some kinds of which possess a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most complex smectic device. Within it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are tilted, as displayed in the figure. The host liquid crystal possesses optically active molecules, and a minor consequence of the optical activity and the angle 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 must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The consequential change in optical properties can cause a change from light to dark when one or more polarizers are employed.

SSFLC devices have been commercialized for big passive-matrix displays, but their expense and complex nature has stopped them from enjoying any particular progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as parts in projection systems or as viewfinders in digital cameras. Their immediate reaction allows them to be employed 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 pulsing (around 100 cycles a second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods then to a nontransmissive state for the blue period, displaying the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture objects, the chair may be the most important. While most of the other objects (save the bed) are meant to support objects, the chair supports our human form. The term chair is looked upon here in the larger sense, from stool to throne to derivative pieces including a 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 defined.

The social history of the chair is as interesting as its history as an art and craft. The chair is not only a physical support or aesthetic creation; it historically was a symbol of social placement. From the past royal courts there were plain signifiers between possessing a chair with arms, sitting on a chair with a back but no arms, or worse having to make do with a stool. In the 20th century, a director’s and/or manager’s chair has been seen as an indicator of superior status, as well as in democratic government meeting the speaker sits on a raised floor.

In a furniture creation, the chair ranges from a wealth of different purposes. There are chairs created to match man’s age and physical form (the high chair, the wheelchair) and to denote his status in society (the executive chair, the throne). In past times there were chairs used for birth (birth chairs); since the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our modern lifestyle has designated particular chairs in automobiles and aircraft. All these chair shapes have adapted to match to growing human uses. For its unique importance with man, the chair lives to its full meaning only when utilised. Although it doesn’t make any difference to one’s appreciation of a cupboard or a set of drawers whether there is anything inside or not, a chair is seen best and fairly evaluated by a person using it, for chair and sitter need each other. Thus the different parts of the chair have been named likened to the names of our human body: arms, legs, feet, back, and seat.

Because the elemental purpose of a chair is to support a body, its credit is tested principally from how well it measures up to this practical job. In the structure of a chair, the maker is restricted in certain static laws and principal measurements. Inside these boundaries, however, the chair designer has awesome freedom.

The history of the chair extended over an era of several thousand years. There existed cultures that held unique chair types, seen of the foremost work in the areas of skill and aesthetics. Among these such peoples, particular mention 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 lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the objects of masterful make, were seen from tomb findings. The first one of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs shaped as akin to those of some animal, a curved seat, and leading to a sloping back supported with vertical stretchers. In this way a solid triangular form was created. There seemed to be no notable change in the design of Egyptian thrones and chairs for common populace. The simple change lied in the level of ornamentation, in the particulars of costly inlays. The Egyptian folding stool likely was designed for an easily packed seat for soldiers. As a camp stool the chair existed til much later points in time. But the stool also played the character of a ceremonial seat, its original history as a folding stool fast forgotten. This can now be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the shape of folding stools but aren’t able to be folded as the seats are worked out of wood. The easy structure of the folding stool, composed of two frames that turn on metal bolts and hold a seat of leather or fabric fastened between them, came up somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this kind is the folding stool, made from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not from any ancient item still in form but as seen in a large amount of pictorial evidence. The significant kind is the klismos placed on the Hegeso Stele at the Dipylon burial place just out of Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs would be visible. These unusual legs were most likely created out of bent wood and were thus subjected to huge pressure from the weight of the sitter. The joints securing the legs to the frame of the seat were therefore super strong and were plainly denoted.

The Romans emulated the Greek chair; quite a few casts of seated Romans display evidence of a more heavyset and are a kind of crudely designed klismos. Both kinds, the light and heavy, were revived during the Classicist period. The klismos style can be seen in French Empire chairs, in English Regency, and in some special forms of marked iconicism around Denmark and Sweden circa 1800.

China
The progression of the chair in China cannot be followed as long as the progression of the chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed series of drawings and works of art has been kept, detailing the interior and exteriors of Chinese houses and their furniture. Also kept from the 16th century are a collection of chairs crafted from wood or lacquered wood, that display an intriguing likeness to representations of older chairs.

As in Egypt, there existed two standard chair forms in China: a chair that had four legs and a folding stool. The four-legged chair was seen both with and without arms though never missing the square seat and straight stiles (vertical side supports) to give support to the back. In one form, it has been seen, the stiles could be slightly curved by the arms so as to fit the form of the S-shaped back splat (the main upright of a chairback). Each of the three sections were mortised on the yoke-like top rail. Despite that the innovation of the back splat had an influence on English chairs in the Queen Anne period, wooden members that only to a limited ability stabilise corner joints (and furthermore were loose as a result) represent an element signatory to Chinese chairs. The four legs sit through the seat frame, which ends around the rounded staves. Members are round in section or has rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited seat. These chairs demanded of the sitter to stay stiff and upright; for when too much pressure is exerted on the back, the chair has a tendency to fall. In patriarchal Chinese households of this epoch armchairs most likely were reserved for senior family members, for they were respected greatly.

The Chinese folding stool is understood to have travelled to China from the West. It does not vary so very much from the Egyptian and Scandinavian folding stools, but it possesses a change in that the top rail is prettily joined to the two legs of the stool by using a curved member, which is usually provided with metal mounts. From a Western point of view the resultant effect of both these furniture designs is stylized. The structure and decoration parts are combined in a style that is all at once both naïve and refined. The piecemeal appearance is an upshot of the manner that the individual parts do not seem to have been joined together by either glue or screws, but were mortised with one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its name on the chair. Works of art project a design of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to produce a pattern of little pads. The front board and a similar board at the back could be folded after unscrewing some tiny iron hooks. Therefore the chair was an easily portable piece of furniture while traveling which, at the same time, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be 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 type of chair might also be made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not decided that the innovation actually was instigated in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was produced in impressive numbers, as surmisable from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up by a wall. The design asserts itself by its shapely 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, as developed in Paris around 1750—disseminated through most of Europe and was imitated or copied into the mid-20th century. The chair owes this popularity to a combination of relaxation and charm. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are tiny upholstered pads on the armrests. Smooth transitions are made between seat frame, legs, and back conceal all the joints, which are strongly constructed on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of relatively thick dimensions; but all members are deeply molded, all superfluous wood has been removed, and more upmarket designs would be further embellished with highly delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all the upholstery on the seat, back, and armrests; cane is in some cases used in place of upholstery.

English chairs of the 18th century were more varied in style than the French. The French taste for stylistic uniformity, which came from the highest circles in Paris and Versailles within most of France and found favour in several 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 styles 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 charting of the money values of the function of a business. Bookkeeping creates the numbers from which accounts are made but is a distinct process, preliminary to accounting.

Essentially, bookkeeping records two parts of information: (1) the current value, or equity, of the enterprise and (2) the changes in value—profit or loss—taking place in the business within a singular time period.

Management officials, investors, and credit grantors all demand this information: management so as to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to interpret the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to judge the financial statements of a business in deciding whether to grant a loan.

Traces of financial and numerical records can be seen for almost every society with a commercial history. Records of trading contracts have been discovered in the remains of Babylon, and accounts for both farms and estates had been made in ancient Greece and Rome. The two-entry manner of bookkeeping came up with the development of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were produced in the 15th century in many Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial books a paramount factor. The ancestry of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, in part, assisted to form it. The global movement of industrial and commercial activity needed better sophisticate decision-making methods, which in turn called for better 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 need for information; business entities had to provide information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the requirement for bookkeeping for departmental operations became higher.

While bookkeeping methodology can be rather detailed, it is all based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and such), and the ledger has the record of individual accounts. The daily records in the journals are written in the ledgers.

Each month, generally, an income statement and a balance sheet are made from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to show an analysis of those changes that happen in the business equity from the operations of the period. The balance sheet gives the financial situation of the business at any particular point derived 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 produced 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.
