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

The typical question asked when looking for a new projector for the home, office, or classroom is: do I take an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two top projector imaging technologies. With so many company brands and models available, it can be confusing for consumers to pick between both technologies. The simple fact of the matter is that LCD projectors give far better image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with reproducing a similar rate of image quality.

Think of a set of blinds in your household on your bedroom window. By a twist of a rod you can make the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector operates. Each pixel operates like a single shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from when the projector is turned on to when the content reaches your screen is absolutely significant to 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 different LCD panels. The 3 LCD panels create the elements of the image by processing each pixel on and off. The pixels are then meshed in a glass prism to form the projector image. Something to understad about LCD projectors is that all three colours are sent onto your screen all at the same time. The way a DLP projector works is widely different and even the produced image appears is not the same. With DLP, white light from the lamp is projected through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to making an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to construct 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 combine each coloured element of the image into a full image. From LCD projectors, all colours are available all the time to offer the highest brightness and great colour accuracy. In DLP, only one colour is available at once, resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment for the colour wheel to improve overall brightness, but this goes and lessens colour accuracy.

I hear in forums all the time that DLP gives a higher contrast ratio and therefore must be better. For those who do not know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is able to produce. DLP projectors do have high contrast specifications in comparison to most LCD projectors. Initially, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room in which the projector is used. Do not be duped by contrast specifications on websites and in brochures.

When the content you are trying to project needs moving images, DLP projection technology also has image marks, or ‘artifacts’. The most common 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 between the time red, blue and green colours are shone. LCD projectors do not have this characteristic because the colours are projected simultaneously. DLP builders have formed 3DLP solutions using 3 chips to solve the colour break up problem, but the expense of these projectors make them hardly practical for the large part of businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and remember how the various colours of light refract differing amounts when directed through the same lens. The downside with DLP projectors is that they have the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in different ways. Most of the time with a DLP projector, an extra yellow colour will be projected above and a superfluous blue will appear below an image of something as simple as a single black line. In manufacturing LCD projectors can be adapted to remove these effects on the projected image, because each colour is processed on its own LCD panels.

The isolated actual advantage (excluding price) with taking a DLP projector is its smaller total size and weight. However, this is only relevant with regard to transporting the device and must be traded off against the image superiority of LCD projectors. If resulting picture quality is crucial to you, then the choice is a no-brainer. Choose an LCD projector! LCD projectors will constantly create bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch came to dominance in sea power during the 17th century, the initial yacht had been a pleasure craft used first by royalty and then by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his reaffirmation 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, ruled 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting became popular with the rich and royalty, but after that time the trend did not last.

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

Yacht racing was seen in some ordered method on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it came to be named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been formed at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the perpetual location of British yacht racing. The association at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing races for great stakes were held, and the social life was wonderful. Ultimately Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English held control. Sailing was largely for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in the 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 aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The craft of large yachts was first greatly put upon by the victory of America, which was created by George Steers for a group led 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 built in the modern sense, with only a model for an outline. Not until the later 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 craft of sails and rigging what such study had previously done for hulls.

Because almost all sailboats had to be individually custom-built, there came a need for handicapping boats before the one-design class boats were made. Therefore, a rating rule was decreed, which ended up in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are created to single requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between such boats can be held on an even basis with no handicapping necessary. A great example is the standard International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting was done mostly for the royal and the rich, money was no issue, and the size of boats grew, in both length and weight. The rise and desire of smaller yachts occurred in the later 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 trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the hardiness of smaller boats. Thereafter in the 20th century, notably after World War II, smaller racing and recreational boats became more common, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, in which steam was set to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were used increasingly in personal boats. Bigger power yachts were furthered to a high element, and long-distance cruising became a favourite activity of the well off. The first power yachts were paddle-wheel boats; these then gave way to those powered by the completely submerged screw or propeller kind of propulsion. As in the case of naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for a number of years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were exclusively power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a rise in the design of more sizeable 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 manned by a crew of over 150. The Mayflower, purchased 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 larger and more reliable internal-combustion engines were developed, many big craft were using them for power. The establishment of the diesel engine, with heavy oil for fuel, progressed for World War I. During the decade after, large power-yacht building blossomed, climaxing in the Orion (1930) at 3,097 tons. During that period the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power craft lessened after 1932, and the style from then was for smaller, less expensive craft. After World War II, a lot of small naval boats were sold to private owners for conversion to yachts. At the late 20th century, yachting is a globally popular sport enjoyed by thousands of yachtsmen who are actually sailing and upkeeping their own small recreational yachts. The number of craft and yachtsmen is increasing steadily, not only in the traditional areas by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the impact they have on the placement of income and wealth. A proportional tax is one that places the same relative liability on all taxpayers—i.e., where tax liability and income increase in the same scale. A progressive tax is recognised by a larger than proportional increase in the tax burden in regard to the rise in income, and a regressive tax is characterizable by a less than proportional rise in the comparable liability. Ergo, progressive taxes are thought of as reducing a lack of equality in income distribution, while regressive taxes may have the effect of increasing these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, might become less so in the upper-income group—especially if a taxpayer is allowed to reduce his tax base by claiming deductions or by leaving out particular income parts from his taxable income. Proportional tax rates which are applied to lower-income categories would also be more progressive if exemptions of a personal nature are made.

Income measured over the course of a given year may not absolutely give the most accurate measure of taxpaying requirement. For example, transitory rises in income might be saved, and within temporary declines in income a taxpayer may opt to pay for consumption by reducing savings. Therefore, if taxation is held in comparison along with “permanent income,” it would be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (with the exception of those on luxuries) are mostly regressive, because the portion of one’s income consumed or spent on specific goods decreases as the rate of personal income is raised. Poll taxes (also called head taxes), levied as a flat amount per capita, patently are regressive.

It is complicated 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 determining who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being considered.

In regarding the economic purposes of taxation, it is important to differentiate between several concepts of tax rates. The statutory rates will be specified in the legislation; often these are marginal rates, but in some cases they are median rates. Marginal income tax rates denote the fraction of incremental income taken by taxation when income grows by one dollar. Ergo, if tax burden increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax statutes commonly contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates need to take into account provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than nominated within the statutory rates. Since marginal rates display how after-tax income changes in response to changes in before-tax income, they are the necessary 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, since 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 holds that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates display the percentage 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 commonly increase with income, both because personal allowances are allowed for the taxpayer and dependents and also due to that marginal tax rates are graduated; conversely, preferential treatment of income received fundamentally by high-income households could dampen these effects, forcing regressivity, as displayed by average tax rates that decline as income increases.

The Development of Data Projectors

The LCDs used in projection systems are most often small reflective or transmissive panels illuminated by a powerful arc lamp source. A number of lenses expands the reflected or transmitted image and sends it onto the screen. With front-projection systems the LCD is located on the same side of the screen as the viewer, however in rear-projection systems the screen is illuminated from behind. Projectors of greater cost and capability can be found with three separate LCD panels, creating separate red, green, and blue images that come together to create a coloured picture on the screen.

The growing requirement for visual presentations has granted a special emphasis on the switching speed of liquid crystals. This has required the manufacture of devices using smectic liquid crystals, certain ones of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed smectic device. Inside it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as shown in the figure. The host liquid crystal possesses optically active molecules, and a minor consequence of the optical activity and the tilt 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 in the plane of the layers. Therefore, there must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The respective change in optical properties can make a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been commercialized for bigger passive-matrix displays, but their expensiveness and intricacy has hindered them from enjoying any great movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be made use of in time-sequential colour systems, in which high cost colour filters are removed for a coloured backlight that flashes red, green, and blue in fast succession (approx 100 cycles per second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods but then to a nontransmissive state during the blue period, having the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture needs, the chair might be of the most importance. While the majority of other items (save for the bed) are designed to support objects, the chair supports your human form. The term chair is intended to be viewed here in the most general sense, from stool to throne to developed kinds including the bench and sofa, which can be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously definitive.

The social history of the chair is as curious as its history as a creative art. The chair is not just a physical support or aesthetic creation; it is historically an indicator of social rank. In the old royal courts there were plain connotations between being seated on a chair with arms, sitting on a chair with a back but without arms, and having to sit on a stool. In the 20th century, a director’s and manager’s chair has become a symbol of superior dignity, as well as in democratic governments the speaker sits on a higher level.

As a furniture construction, the chair ranges from a range of different models. There are chairs manufactured to attend to man’s age and physical capabilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). In historical times there were chairs for birthing (birth chairs); since the 20th century, there have been chairs for ending life (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern day living has designated particular chairs for use in automobiles and aircraft. Each of these chair shapes has been evolved to suit to growing human uses. Due to its particular association with man, the chair appears to its full importance only when utilised. While it doesn’t make any difference to one’s appreciation of a cupboard or a bureau if there might be things inside or not, a chair is seen best and judged with a person sitting on it, because chair and sitter need one another. Thus the different areas of the chair are named according to the names of our human parts: arms, legs, feet, back, and seat.

Because the simple function of your chair is to support a body, its worth is evaluated primarily for how suitably it measures up to this practical purpose. Within the manufacture of the chair, the carpenter is limited for the static legislation and principal measurements. Inside these boundaries, however, the chair maker has extensive freedom.

The history of the chair extended over an era of several thousand years. There are cultures that made unique chair forms, expressions of the foremost endeavour in the areas of skill and creativity. Among these such peoples, a mention should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of expert make, are now found from findings made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair had four legs crafted similar to those of some animal, a curved seat, and with a sloping back supported above vertical stretchers. In this way a strong triangular construction was obtained. There was in our knowledge no particular differentiation from the structure of Egyptian thrones and chairs for regular peasantry. The only difference lies in the complexity of ornamentation, in the choice of pricier inlays. The Egyptian folding stool most probably was manufactured as an easily stored seat for soldiers. As a camp stool this chair stayed around during much later times. But the stool also then was created as the role of a ceremonial seat, its technical task as a folding stool ignored or forgotten. This can now 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 were constructed in the construction of folding stools but can not be folded because the seats were worked out of wood. The simplistic make of the folding stool, made of two frames that cycle on metal bolts and hold a seat of leather or fabric fastened between them, appeared at some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this type is the folding stool, crafted from ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not from any ancient object still extant but in a variety of pictorial objects. The best recognised is the klismos depicted on the Hegeso Stele at the Dipylon burial location just out of Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, only two of those legs were displayed. These curving legs were considered to be manufactured in bent wood and were thus put under a large amount of pressure from the weight of the sitter. The joints fastening the legs to the frame of the seat would have had to be therefore super solid and were plainly signified.

The Romans borrowed from the Greek chair; quite a few casts of seated Romans offer evidence of a more heavyset and in appearance rather less intricately crafted klismos. Both types, light and heavy, were seen again within the Classicist epoch. The klismos style can be evidenced in French Empire styles, in English Regency, and in some special types of notable uniqueness of Denmark and Sweden around 1800.

China
The progression of the chair in China cannot be tracked as well as the progression of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged collection of images and works of art was kept, showing the interiors and exteriors of Chinese homes and their furniture. Another preservation of the 16th century are some chairs crafted from wood or lacquered wood, that hold an astonishing resemblance to images of past chairs.

Just as in Egypt, two particular chair forms existed in China: a chair having four legs and a folding stool. That four-legged chair was designed both with and without arms but always with a square seat and straight stiles (upright side supports) to hold up the back. In one image, it has been found, the stiles had been marginally curved by the arms to sit right with the angle of the S-shaped back splat (the centre upright of a chairback). Together, all three areas were mortised onto the yoke-like top rail. Despite that the idea of this back splat then had a foundation for English chairs during the Queen Anne period, wooden items that merely to a particular extent embolden corner joints (and were loose to top that off) represent a signature solely to Chinese chairs. The four legs pass through the seat frame, which finishes upon the rounded staves. Each member is round in section or is given rounded edges—references perchance to the bamboo tradition. The seat is uncomfortable and might have had a plaited bottom. These chairs required of the sitter to hold themselves stiff and upright; for if too much weight is placed on the back, the chair has a way of toppling over. In patriarchal Chinese houses of this era armchairs likely were reserved only for elderly persons, for they were respected greatly.

The Chinese folding stool is presumed to have been brought to China from the West. It does not differ much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is prettily held to the two legs of the stool by use of a curved member, which is more often than not seen with metal mounts. From a Western point of view the resultant effect of these two furniture styles is stylized. The construction and decorative aspects are combined in a style that is both naïve and refined. The pieced-together appearance is an upshot of the way that the individual members do not appear to have been fixed together by use of either glue or screws, but were mortised into one another and held in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also put its name on the chair. Artworks display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between, stitched to produce a pattern of tiny pads. The front board and a related board in the back could be folded after loosening some small iron hooks. Thus the chair was a portable piece of furniture while traveling which, at the same period, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair can be evidenced in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair is also seen in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the style actually started in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of slender measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was produced in large quantities, as can be surmised from one of Abraham Bosse’s engravings, in which an entire row of those chairs lined up along a wall. The style asserts itself by virtue of its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as created in Paris around 1750—spread over most of Europe and was imitated or copied during the mid-20th century. The chair owes the popularity to a combination of leisure and delicacy. The seat suits to the human body and allows a relaxed sitting 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 made between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of rather thick measurements; but all the members are deeply molded, all extraneous wood has been sanded away, and more upmarket chairs may be further embellished with special delicate and decorative carving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all upholstery on the seat, back, and armrests; crosshatched cane is in some cases used as an alternative to upholstery.

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

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

Late 18th to 20th century
Within 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 products 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, suggest 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 operation of a business. Bookkeeping gives the information from which accounts are made but is a previous process, prior to accounting.

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

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

Bits and pieces of financial and numerical record charts have been seen for just about every society with a commercial history. Records of trade contracts have been found in the remains of Babylon, and accounts for both farms and estates were kept in ancient Greece and Rome. The dual-entry process of bookkeeping started with the progression of the business republics of Italy, and manuals for bookkeeping were produced within the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial records a must-have. The ancestry of bookkeeping, in fact, reflects the past of commerce, industry, and government and, partially, assisted to form it. The worldwide spread of industrial and commercial activity required better cosmopolitan decision-making processes, which then required more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more significant and resulted in increased demand for information; business firms had to provide information to list 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 their inner operations increased.

Although bookkeeping methods can be very detailed, all of it is based on two kinds of books used in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger should have the details of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are prepared from the trial balance posted within the ledger. The job of the income statement or profit-and-loss statement is to show an analysis of those changes that have taken place in the enterprise equity as a result of the events of the period. The balance sheet displays the financial condition of the corporation at a particular date regarding 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.
