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

The most typical question heard when looking for a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many brands and different types available, it can be confusing for clients to make a choice between those technologies. It comes down to the fact that LCD projectors provide far better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with creating the same rate of image quality.

Imagine a set of blinds in your home covering your bedroom window. By pulling on a rod you can make the shutters open or closed, depending on if you want to let light in or not. That is exactly how an LCD projector functions. Each pixel operates like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the content reaches your screen is vitally important for image quality, brightness and colour accuracy. LCD projectors shine 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 create the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to form the projector image. A significant point to remember about LCD projectors is that all three colours are sent onto your screen at once. The way a DLP projector runs is totally different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is projected through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image casts a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to construct the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into the full image. With LCD projectors, all colours are available all the time to form the best brightness and spectacular colour accuracy. In DLP, only one colour is available at once, and so resulting in lower colour brightness and accuracy. Some manufacturers have put a white segment into the colour wheel to improve brightness generally, but this also detracts from colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and ergo must be better. 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 machine is able to produce. DLP projectors do possess high contrast specifications when compared to most LCD projectors. At first glance, this appears to be a benefit, however, in reality, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you plan to view requires moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change position between the time red, blue and green colours are shone. LCD projectors do not have this downside because the colours are processed at once. DLP manufacturers have created 3DLP solutions using 3 chips to answer the colour break up artifacts, but the price tag of these projectors make them almost impossible for the large part of 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 they taught you how the various colours of light refract various amounts when projected through the same lens. The downside with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are different and refract light in different ways. Usually with a DLP projector, some yellow colour will be projected above and some extra blue will come through below an image as simple as a single black line. In building LCD projectors can be adapted to minimize these effects on the projected image, because each colour is refracted on its own LCD panels.

The sole veritable benefit (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant to portability and has to be traded off against the image benefits of LCD projectors. If overall picture quality is vital to you, then the answer is easy. Go for an LCD projector! LCD projectors will constantly create bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the initial yacht had been a pleasure craft used initially 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 matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting was found to be classy for the affluent and nobility, but after that period the fashion did not last.

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

Yacht racing began in some organized 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 ascended to monarchy in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, 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 funding made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British yacht racing. The society at Cowes became the Royal Yachting Club, again at the ascension of George IV. Each member was required to possess boats of at least 20 tons (20,321 kg). Sailing tests for great stakes were held, and the social life was lovely. It came to be that the Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English took dominance. Sailing was for the most part for fun and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a benchmark of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The style of large yachts was first greatly impacted by the success of America, which was designed by George Steers for a syndicate started 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 built in a contemporary sense, with merely 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 use of the science of aerodynamics do for the craft of sails and rigging what it had done earlier for hulls.

Because most of all sailboats had to be individually manufactured, there came a requirement for handicapping boats previous to the one-design class boats were designed. Hence, a rating rule was created, which is found in the International Rule, adopted in 1906 and revised in 1919. Today, one of the most rapidly growing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between these boats can be done on an even par with no handicapping required. A great example is the standard International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

So long as yachting was done mostly 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 boats happened in the later 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of small craft. Following this in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, when steam began to emulate sail power in market vessels, the steam engine, and later the internal-combustion engine, were employed increasingly in personal craft. Sizeable power yachts were developed to a high standard, and long-distance travel turned into a favourite occupation of the affluent. The early power yachts were paddle-wheel boats; these then gave rise to those powered by the wholly submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries with both sail and power were the yacht fashion for many years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the construction of large steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 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 gave active service in World War II.

As larger and more reliable internal-combustion engines were created, many bigger yachts were using them for power. The establishment of the diesel engine, with heavy oil for fuel, was furthered during World War I. In the decade following that, big power-yacht creation blossomed, hitting a climax in the Orion (1930) at 3,097 tons. From that point the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats fell away after 1932, and the fashion thereafter was for smaller, less expensive boats. After World War II, lots of small naval craft were traded by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally popular activity enjoyed by thousands of yachtsmen individually owning and maintaining their own small leisure boats. The popularity of craft and yachtsmen has increased steadily, not only in the traditional areas on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are categorized by the effect they have on the placement of income and wealth. A proportional tax is a tax that imposes the same relative burden on all the taxpayers—i.e., in the case where tax liability and income grow in equal scale. A progressive tax is recognised by a more than proportional increase in the tax onus in relation to the rise in income, and a regressive tax is recognisable by a less than proportional rise in the comparative liability. Ergo, progressive taxes are viewed as removing the lack of equality in income distribution, but regressive taxes may have the effect of increasing these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, might become less so for the upper-income group—especially if a taxpayer is permitted to lower his tax base by nominating deductions or by removing certain income aspects from his taxable income. Proportional tax rates that are applied to lower-income demographics will also be more progressive if such exemptions of a personal nature are declared.

Income measured over the period of a year might not definitely give the most suitable measure of taxpaying status. For example, transitory rises in income might be saved, and in temporary declines in income a taxpayer may elect to provide for consumption by taking from savings. Ergo, if taxation is compared along with “permanent income,” it will be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (save luxuries) are generally regressive, because the dissemination of individual income consumed or spent on specific goods declines as the level of personal income is raised. Poll taxes (also termed head taxes), nominated as a standard amount per capita, clearly are regressive.

It is not simple to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden rests essentially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effects of taxation, it is important to distinguish between varied points of tax rates. The statutory rates are dictated in law; often these are marginal rates, but in some cases they are median rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income rises by one dollar. Ergo, if tax burden rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax regulations often contain graduated marginal rates—i.e., rates that increase as income grows. Careful analysis of marginal tax rates must consider provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points higher than indicated in the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, because it may rely on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates show the fraction of total income that is paid in taxation. The pattern of average rates is the one that is necessary for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates commonly rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households could dampen these effects, allowing regressivity, as displayed by average tax rates that lower as income grows.

The Development of Data Projectors

The LCDs used in projection systems are usually small reflective or transmissive panels lit up by a bright arc lamp source. A line of lenses enlarges the reflected or transmitted image and then sends it on a screen. For front-projection systems the LCD is situated on the same side of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of greater cost and capability sometimes use three separate LCD panels, reflecting separate red, green, and blue images that blend to form a coloured image on the screen.

The growing desire for film presentations has granted a special emphasis on the switching speed of liquid crystals. This has required the creation of items using smectic liquid crystals, some kinds of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most complex smectic device. Inside it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal possesses optically active molecules, and a subtle turn up of the optical activity and the tilt 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 in the plane of the layers. Hence, there has to 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 right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The respective change in optical properties can effect a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been publicized for larger passive-matrix presentations, but their expense and complex nature has impeded them from making any particular progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their speedy response allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in quick succession (about 100 cycles every second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods then to a nontransmissive state in the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture needs, the chair could be the paramount one. While the majority of other forms (save the bed) are meant to support objects, the chair supports a human form. The term chair is regarded here in the most common sense, from stool to throne to developed types like a bench or sofa, which should be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as stimulating as its history as an art and craft. The chair is not only a physical support or an aesthetic piece; it is historically a signifier of social ranking. In the historical royal courts there were important differences between possessing a chair with arms, or a chair with a back but no arms, or worse having to make do with a stool. Since the past century, the director’s and manager’s chair has developed a signifier of superior status, and in democratic government meeting the speaker sits on a high-set platform.

As a furniture form, the chair holds a range of different models. There are chairs created to match man’s age and physical abilities (the high chair, the wheelchair) and for his rank in society (the executive chair, the throne). Since historical times there were chairs for birthing (birth chairs); since the 20th century, there have been chairs used to die in (the electric chair). There are chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed unique chairs for use in automobiles and aircraft. All these chair types have been changed to match to changing human uses. Because of its particular association with man, the chair appears to its full meaning only when being used. Although it is irrelevant to one’s appreciation of a cupboard or a bureau whether there might be things inside or not, a chair is really seen best and tested by a person using it, for chair and sitter suit one another. Thus the different limbs of a chair are given names corresponding to the names of our human body: arms, legs, feet, back, and seat.

Because the elementary role of a chair is to support our human body, its credit is evaluated primarily from how completely it fulfills this practical role. Within the creation of a chair, the maker is restricted with the static legislation and principal measurements. Within these boundaries, however, the chair designer has great freedom.

The history of the chair lasted over an era of several thousand years. There were societies that made significant chair types, seen of the topmost task in the spheres of craft and art. From those peoples, individual mention must 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of masterful scheme, were found from findings made in tombs. The first of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs structured as akin to those of a particular animal, a curved seat, and leading to a sloping back supported with vertical stretchers. In this way a solid triangular construction was created. There was from our view no marked variation between the structure of Egyptian thrones and chairs for regular peasantry. The general difference existed in the complexity of ornamentation, in the selection of more expensive inlays. The Egyptian folding stool most likely was made for an easily stored seat for army. As a camp stool this stool stayed around during much later periods. But the stool also then was created for the purpose of a ceremonial seat, its original job as a folding stool neglected or forgotten. This can from today be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but cannot be folded because the seats were made of wood. The simplistic construction of the folding stool, made of two frames that rotate on metal bolts and have a seat of leather or fabric held between them, came up somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this kind is the folding stool, made from ashwood, found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not with any ancient specimen still existing but found in a variety of pictorial objects. The iconic kind is the klismos depicted on the Hegeso Stele at the Dipylon burial place near Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of these legs would be displayed. These creative legs were most likely manufactured out of bent wood and were probably needed to bear huge pressure from the weight of the sitter. The joints fastening the legs to the frame of the seat were therefore extremely stable and were plainly signified.

The Romans borrowed from the Greek style; quite a few casts of seated Romans display examples of a denser and which appear to be a somewhat less intricately designed klismos. Both styles, the light and the heavy, were popularised within the Classicist epoch. The klismos style is evidenced in French Empire styles, in English Regency, and in some special brands of considerable uniqueness around Denmark and Sweden during 1800.

China
The progression of the chair in China cannot be tracked as far back as that of Egypt and Greece. Since the Tang dynasty (AD 618–907) a full collection of sketches and paintings was kept safe, showing the inside and outside of Chinese homes and the furniture. Preserved also from the 16th century are a collection of chairs constructed of wood or lacquered wood, that show an astonishing likeness to pictures of ancient chairs.

Same as in Egypt, there existed two iconic chair forms in China: a chair having four legs and a folding stool. The four-legged chair has been designed both with or without arms though always having its square seat and straight stiles (vertical side supports) to hold up the back. In one form, though, the stiles are lightly curved by the arms so as to fit the form of the S-shaped back splat (the centre upright of a chairback). The three parts had been mortised onto the yoke-like top rail. Although the idea of this back splat later had a foundation for English chairs from the Queen Anne period, wooden members that merely to a particular capability support corner joints (and furthermore were loose in the bargain) represent a signature solely to Chinese chairs. The four legs are set through the seat frame, which finishes upon the rounded staves. All the members are round in section or is given rounded edges—referable maybe to the bamboo tradition. The seat is not pleasant and might have had a plaited texture. These chairs required of the sitter to hold themselves stiff and upright; for when too much pressure is exerted on the back, the chair has a habit of falling over. In patriarchal Chinese households of this era armchairs likely were kept only for older persons, for they were given great respect.

The Chinese folding stool is thought to have taken to China from the West. It does not differ so very much from the Egyptian and Scandinavian folding stools, but it possesses a difference in that the top rail is prettily affixed to the two legs of the stool by a curved member, which is more often than not designed with metal mounts. From a Western point of view the ultimate effect of both of these furniture styles is stylized. The constructive and aesthetic aspects are combined in a way that is both naïve and refined. The patchwork appearance is an outcome of the fact that the individual items do not look to have been put together by means of either glue or screws, but are mortised into one another and held in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its mark on the chair. Works of art show a type of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to bring out a pattern of small pads. The front board and a related board at the back could be folded after loosening some tiny iron hooks. In this way the chair was a readily portable piece of furniture when traveling which, in the same time, granted the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be found in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair is also made in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not believed that the form actually started in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in impressive numbers, as can be surmised from one of Abraham Bosse’s engravings, in which there is a whole row of those chairs lined up along a wall. The design asserts itself with its elegant proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, to say, as created in Paris around 1750—conquered most of Europe and was imitated or copied into the mid-20th century. The model owes its popularity to a combination of leisure and delicacy. The seat adheres to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions are achieved between seat frame, legs, and back disguise all the joints, which are constructed solidly on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof have wood of fairly thick measurements; but every member is deeply molded, all extraneous wood has been removed, and more upmarket items might be further embellished with intricately delicate and decorative woodwork. The wood could 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 occasionally used instead of upholstery.

English chairs in the 18th century were more differentiated in form than the French. The French touch for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles within most of France and won 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 popular and was widely distributed throughout the world.

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

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

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

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping gives the numbers from which accounts are drafted but is a different process, prerequisite to accounting.

Essentially, bookkeeping provides two kinds of information: (1) the current value, or equity, of a business and (2) the changes in value—profit or loss—taking placement in the entity during a single period.

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

Evidence of financial and numerical recordkeeping can be found for just about every state with a commercial background. Records of trading contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The two-entry manner of bookkeeping began with the development of the commercial republics of Italy, and tutorials for bookkeeping were created during the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a necessity. The ancestry of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, in some part, assisted to shape it. The worldwide expansion of industrial and commercial activity called for better sophisticate decision-making methodology, which then demanded greater sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government legislature became more significant and resulted in higher demand for information; entities had to show available information to list with 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 departmental operations went up.

Although bookkeeping processes can be rather complex, all are based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, etcetera), and the ledger contains the information of individual accounts. The daily records in the journals are entered in the ledgers.

Every month, generally speaking, an income statement and a balance sheet are made from the trial balance posted within the ledger. The point of the income statement or profit-and-loss statement is to display an analysis of those changes that happen in the ownership equity resulting from the events of the period. The balance sheet shows the financial condition of the corporation at any particular point 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 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 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.
