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

The most common question heard when purchasing a new projector for the home, office, or classroom is: do I take an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two top projector imaging technologies. With so many brands and different types available, it can be difficult for clients to make a choice between those technologies. Ultimately LCD projectors give better image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with creating an equal standard of image quality.

It’s like a set of blinds in your house over your bedroom window. By twisting a rod you can have the shutters open or closed, depending on whether you want to let light in or not. And such is exactly how an LCD projector operates. Each pixel functions like an individual shutter on a set of blinds to either send light through or to block it. DLP on the other hand is created 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 the time the projector switches on to when the picture reaches your screen is absolutely important 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 direct the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by switching each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. An important point to know about LCD projectors is that all three colours are directed onto your projector screen all at the same time. The way a DLP projector operates is totally different and even how an image comes out 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 way of projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into the total image. With LCD projectors, all colours are available all the time to offer the top level of brightness and superb colour accuracy. In DLP, only one colour is available at any given time, resulting in lower colour brightness and accuracy. Some manufacturers have added a white segment into the colour wheel to improve overall brightness, but this then detracts from colour accuracy.

I see in forums all the time that DLP offers a higher contrast ratio and ergo must be superior quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is capable of. DLP projectors do provide high contrast specifications when compared to most LCD projectors. Initially, this appears to be an advantage, however, in reality, the true black level is determined by the ambient light in the room while the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you are trying to bring to life requires moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most commonplace artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change position between the time red, blue and green colours are projected. LCD projectors do not have this disadvantage because the colours are processed at once. DLP developers have developed 3DLP solutions using 3 chips to solve the colour break up problem, but the price tag of these projectors make them hardly practical for many businesses and consumers.

Another difference between LCD and DLP is how they balance for the refractive qualities of light. Take yourself back to high school science, and recall when they taught you how different colours of light refract varied amounts when projected through the same lens. The downside with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light differently. Often with a DLP projector, a spill of yellow colour will show above and some blue will come through below an image as simple as a lone black line. While being built LCD projectors can be set to minimize these effects on the projected image, as each colour is refracted on its own LCD panels.

The sole real advantage (excluding price) with picking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transporting the device and needs to be traded off against the image advantages of LCD projectors. If overall picture quality is vital to you, then the choice is no-brainer. Go with an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the first yacht had been a leisure craft used initially by royalty and secondly by the burghers in the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private challenges. English yachting began 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, sovereign 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting was found to be classy among the affluent and nobility, but after that time the fashion did not last.

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

Yacht racing began in some stipulated fashion on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to the throne in 1820, it came to be called 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 club had been started 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 continued setting of British yacht racing. The association at Cowes became the Royal Yachting Club, again at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the society life was lovely. It came to be that the Royal Yachting Club boats were raised in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English held dominance. Sailing was largely for pleasure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and created a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens instigated the New York Yacht Club 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 latter half of the 19th century. The style of bigger yachts was first heavily put upon by the win of America, which was designed by George Steers for a association 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 crafted in today’s sense, with merely a model for an outline. Not until the second half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what it had previously done for hulls.

Because most of all sailboats had to be individually built, there came a desire for handicapping boats as this was before the one-design class boats were made. Therefore, a rating rule was written, which resulted in the International Rule, taken on in 1906 and edited in 1919. Today, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for those boats can be done on an even par with no handicapping required. A prime example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

For the time that yachting was done largely for the aristocracy and the wealthy, cost was no problem, and the size of boats increased, in both length and weight. The rise and popularity of smaller craft occurred in the second half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of less sizeable yachts. Following this in the 20th century, for the larger part after World War II, smaller racing and leisure craft became commonplace, down to the dinghy, a preferred 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
Following the decade 1840–50, in which steam was set to take the place of sail power in market boats, the steam engine, and later the internal-combustion engine, were increasingly employed in personal boats. Large power yachts were developed to a high degree, and long-distance travel was a favoured occupation of the well off. The early power yachts were paddle-wheel boats; they then gave rise to yachts powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, several yachts were still auxiliaries, but the large part were only power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of bigger steam yachts. In particular within these was the Mayflower (1897) of 2,690 tons, with 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 in World War II.

As more sizeable and more dependable internal-combustion engines were developed, many big yachts started using them for power. The establishment of the diesel engine, using heavy oil for fuel, progressed for World War I. From the decade that followed, bigger power-yacht building grew, hitting a climax in the Orion (1930) at 3,097 tons. From that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power boats lessened in 1932, and the style from then was for smaller, less costly yachts. From World War II, a lot of small naval boats were traded by private owners for conversion to yachts. At the late 20th century, yachting is a internationally loved activity enjoyed by thousands of yachtsmen personally sailing and maintaining their own small recreational craft. The popularity of yachts and yachtsmen increased steadily, not only in the traditional places on the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the impact they have on the distribution of income and wealth. A proportional tax is a tax that imposes the same relative requirement on every taxpayer—i.e., when tax liability and income move in equal proportion. A progressive tax is recognisable by a larger than proportional increase in the tax liability in relation to the rise in income, and a regressive tax is characterizable by a less than proportional growth in the comparative onus. Ergo, progressive taxes are thought of as taking away inequalities in income distribution, while regressive taxes might cause an increase in these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so for the upper-income demographic—especially if a taxpayer is permitted to reduce his tax base by claiming deductions or by leaving out 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 may not definitely offer the best measure of taxpaying status. For example, transitory increases in income may be saved, and within temporary declines in income a taxpayer could decide to pay for consumption by reducing savings. Thus, if taxation is held in comparison with “permanent income,” it will be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (except luxuries) are generally regressive, because the portion of own income consumed or spent for a specific good lowers as the amount of personal income grows. Poll taxes (also called head taxes), levied as a standard amount per capita, patently are regressive.

It is hard to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden lays essentially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic effect of taxation, it is important to distinguish between varied ideas of tax rates. The statutory rates will be nominated in legislature; commonly these are marginal rates, but sometimes they are mean rates. Marginal income tax rates note the fraction of incremental income that is taken by taxation when income grows by one dollar. So, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that rise as income grows. Structured analysis of marginal tax rates must regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the necessary ones for regarding incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applicable to income from business and capital, as it may be dependant on such considerations 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 display the fraction of total income that is taken in taxation. The pattern of average rates is the one that is necessary for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates usually rise with income, both because personal allowances are granted for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the flip side, preferential treatment of income received mostly by high-income households may dwarf these effects, forcing regressivity, as indicated by average tax rates that decline as income grows.

The Development of Data Projectors

The LCDs built in projection systems are usually small reflective or transmissive panels set off by a powerful arc lamp source. A line of lenses expands the reflected or transmitted image and then casts it on the screen. In front-projection systems the LCD is located on the same area of the screen as the viewer, although in rear-projection systems the screen is lit up from behind. Projectors of higher cost and capability might be found with three discrete LCD panels, creating separate red, green, and blue images that combine to reflect a coloured image on the screen.

The increasing desire for video displays has placed a special emphasis on the switching speed of liquid crystals. This has required the manufacture of devices utilizing smectic liquid crystals, certain ones of which have a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most sophisticated smectic device. Within it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are tilted, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible outcome of the optical activity and the slant of the molecules is the presence 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 throughout the plane of the layers. So, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired up to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark if one or more polarizers are employed.

SSFLC devices have been marketed for larger passive-matrix displays, but their expensiveness and detail has impeded them from having any particular effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be made use of in time-sequential colour systems, in which costly colour filters are removed for a coloured backlight that flashes red, green, and blue in fast pace (around 100 cycles every second). For example, the liquid crystal could be switched to a transmissive state during the red and green periods then to a nontransmissive state in the blue period, with 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 could be primary. While most of the other pieces (except the bed) are meant to support objects, the chair supports the human form. The term chair is intended to be viewed here in the most open sense, from stool to throne to complex items for example the bench and sofa, which might be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently labeled.

The social history of the chair is as stimulating as its history as a creative art. The chair is not merely a physical support and aesthetic piece of art; it can also be a signifier of social ranking. At the old royal courts there were plain differences between having a chair with arms, on a chair with a back but no arms, or worse having to cope with a stool. In the past century, a director’s and/or manager’s chair has become a signifier of superior dignity, and in democratic government meeting the speaker sits on a higher platform.

In a furniture construction, the chair can be utilised for a wealth of different makes. There are chairs designed to attend to man’s age and physical capabilities (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). Since historical times there were chairs to be born in (birth chairs); since the 20th century, there have been chairs used to die in (the electric chair). We design chairs with one, two, three, and 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 modern lifestyle has derived particular chairs in automobiles and aircraft. All of these chair forms has evolved to conform to different human uses. For its particular importance with man, the chair comes to its full purpose only when in use. While it is irrelevant to one’s appreciation of a cupboard or a set of drawers if there are items inside or not, a chair is best seen and judged with a person utilising it, because chair and sitter suit each other. Thus the different elements of a chair were given labels like the elements of the human parts: arms, legs, feet, back, and seat.

Because the elementary purpose of the chair is to support the human body, its credit is valued generally for how well it fulfills this practical use. In the design of a chair, the designer is restricted under some static rules and principal measurements. Through these rules, however, the chair maker has marvellous freedom.

The history of the chair extends over dates of several thousand years. There is evidence of cultures that have created iconic chair shapes, expressions of the highest craft in the areas of craft and design. Out of such civilisations, particular 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 items of skilled design, were a finding from tomb discoveries. The first one of these two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have had four legs crafted akin to those of a designated animal, a curved seat, and leading to a sloping back supported from vertical stretchers. From this design a stable triangular design was made. There seems to be no significant change from the design of Egyptian thrones and chairs for common people. The main difference was in the intricacy of its ornamentation, in the particulars of more costly inlays. The Egyptian folding stool most likely was developed as an easily carried seat for army soldiers. As a camp stool the chair persevered during much later times. But the stool then also was created as the use of a ceremonial seat, its original function as a folding stool being forgotten. This can from today be observed, 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 are made in the shape of folding stools but aren’t able to be folded as the seats are formed with wood. The easy structure of the folding stool, composed of two frames that cycle on metal bolts and hold a seat of leather or fabric set between them, also appeared but some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this type is the folding stool, made of ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is seen not as any ancient object still around but as seen from a wealth of pictorial evidence. The most recognisable is the klismos seen on the Hegeso Stele at the Dipylon burial ground by 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 could be displayed. These curving legs were understood to have been created from bent wood and were likely to have been had a large amount of pressure with the weight of the sitter. The joints joining the legs to the frame of the seat were therefore super stable and were clearly pointed out.

The Romans embued the Greek designs; existing statues of seated Romans show designs of a more heavyset and which appear to be a rather crudely designed klismos. Both types, the light or the heavy, were brought back within the Classicist period. The klismos design is evidenced in French Empire chairs, in English Regency, and in some special kinds of considerable individuality around Denmark and Sweden around 1800.

China
The history of the chair in China isn’t able to be tracked as far back as the progression of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken folio of images and artworks had been protected, with images of the interiors and outside of Chinese households and the designs of furniture. Preserved also from the 16th century are some chairs of wood or lacquered wood, that show an amazing resemblance to pictures of ancient chairs.

Same as in Egypt, two iconic chair forms existed in China: a chair having four legs and a folding stool. The four-legged chair was seen both with or without arms but always with the square seat and straight stiles (upright side supports) to give support to the back. In one style, it has been found, the stiles were marginally curved above the arms for the purpose of fit the angle of the S-shaped back splat (the main upright of a chairback). All three areas were mortised into the yoke-like top rail. Although the style of the Chinese back splat later had an inspiration for English chairs during the Queen Anne period, wooden pieces that merely to a particular extent stabilise corner joints (and then are loose in the result) are an element particular to Chinese chairs. The four legs sit through the seat frame, which finishes over the rounded staves. Each member is round in section or has rounded edges—referable perhaps to the bamboo tradition. The seat is unpleasant to sit in and may have a plaited texture. These chairs required of the sitter to stay stiff and upright; when too much pressure is pushed on the back, the chair has a tendency to fall. In patriarchal Chinese homes of this era armchairs probably were kept for older family members, for they were esteemed greatly.

The Chinese folding stool is believed to have been brought to China from the West. It does not differ so very much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is intricately affixed to the two legs of the stool by using a curved member, which is usually possessing metal mounts. From a Western viewpoint the resultant effect of these two furniture forms is stylized. The structure and decoration parts are combined in a way that is all at once both naïve and refined. The pieced-together appearance is an outcome of the way that the individual members do not seem to have been held together with either glue or screws, but had been mortised with one another and locked into position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its mark on the chair. Artworks display 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 show up a pattern of tiny pads. The front board and a related board at the back could be folded after loosening some small iron hooks. Therefore the chair was a portable piece of furniture while traveling which, at the same era, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair is found in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not certain that the style actually started in The Netherlands. Typically, the legs of the chair were smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was manufactured in vast amounts, as indicated from one of Abraham Bosse’s engravings, in which a whole row of such chairs lined up by a wall. The style asserts itself by its elegant proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that is to say, as developed in Paris around 1750—disseminated through most of Europe and has been imitated or copied into the mid-20th century. The style owes such popularity to a combination of comfort and charm. The seat adheres to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Generally 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 conceal all the joints, which are solidly constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof have wood of fairly thick density; but all members are deeply molded, all extraneous wood has been removed, and more expensive chairs may be further embellished with special delicate and decorative engraving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

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

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became 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 versions of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, hint 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 transactions of a business. Bookkeeping gives the figures from which accounts are drafted but is a separate process, preliminary to accounting.

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

Management officials, investors, and credit grantors all demand this information: management in order to analyse the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the upshots of business operations and make decisions for buying, holding, and selling securities; and credit grantors so as to judge the financial statements of an entity in judging whether to allow a loan.

Evidence of financial and numerical recordkeeping are found for nearly every group of people with a commercial background. Records of trading contracts were found in the archaelogy of Babylon, and accounts for both farms and estates have been archived in ancient Greece and Rome. The double-entry way of bookkeeping came up with the furthering of the commercial republics of Italy, and tutorial books for bookkeeping were produced within the 15th century in some Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a paramount factor. The history of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in some part, helped in shaping it. The worldwide movement of industrial and commercial activity needed greater cosmopolitan decision-making processes, which in turn required better sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more important and resulted in greater need 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 demand for bookkeeping for their own departmental operations became larger.

While bookkeeping procedures can be extremely multifaceted, all of it is based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger has the records of individual accounts. The daily records kept in the journals are entered in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to show an analysis of any changes that took place in the business equity resulting due to the operations of the period. The balance sheet shows the financial situation of the entity at any particular point in time taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

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

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

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

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