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

The common question asked when purchasing a new projector for the home, office, or classroom is: do I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many different brands and models available, it can be overwhelming for clients to make a choice between both technologies. The simple fact of the matter is that LCD projectors give superior image quality and colour accuracy. The following article will explain why DLP projectors struggle with bringing up an equal rate of image quality.

Think of a set of blinds in your home over your bedroom window. By twisting a rod you can make the shutters open or closed, according to if you want to let light in or not. This is exactly how an LCD projector operates. Each pixel functions like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is formed 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 point at which the projector is turned on to when the picture reaches your screen is absolutely important to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by cutting 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 make the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to create the projector image. Something to know about LCD projectors is that all three colours are delivered onto your screen simultaneously. The way a DLP projector functions is very different and even the produced image appears 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 making an image creates a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into a single whole image. With LCD projectors, all colours are available all the time to deliver high brightness and spectacular colour accuracy. In DLP, just one colour is available at any given time, resulting in lower colour brightness and accuracy. Some DLP developers have added a white segment for the colour wheel to improve overall brightness, but this also degrades colour accuracy.

I find in forums all the time that DLP provides a higher contrast ratio and as such must be superior. 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 able to produce. DLP projectors do have high contrast specifications compared to a majority of LCD projectors. At first glance, this appears to be a plus, however, in truth, the true black level is determined by the ambient light in the room when the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you are trying to bring to life includes moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector displays with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are projected. LCD projectors do not have this problem because all colours are sent at once. DLP builders have come up with 3DLP solutions using 3 chips to resolve the colour break up problem, but the price of these projectors make them almost impossible for the majority of businesses and consumers.

Another point of difference between LCD and DLP is how they match the balance for the refractive qualities of light. Think back to high school science, and remember when they taught you how various colours of light refract different amounts when directed through the same lens. The disadvantage with DLP projectors is that they utilise the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Most of the time with a DLP projector, a superfluous yellow colour will come up above and some extra blue will come through below an image containing something as simple as a lone black line. During manufacturing LCD projectors can be fixed to take away these effects on the projected image, as each colour is processed on separate LCD panels.

The only actual buy point (excluding price) with buying a DLP projector is its smaller size and weight. However, this is only relevant to mobility and needs to be traded off against the image plusses of LCD projectors. If the result of the picture quality is crucial to you, then the choice is a no-brainer. Go with an LCD projector! LCD projectors will constantly show bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the initial yacht became a leisure craft used initially by royalty and then by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting was found to be classy with the affluent and royalty, but after that period the trend did not last.

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

Yacht racing began in some organized manner on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British yachting. The club at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing races for great bets were held, and the social life was wonderful. It came to be that the Royal Yachting Club boats grew 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 went on when the English gained control. Sailing was mostly for fun and reached its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in that 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 began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of large yachts was first largely put upon by the victory of America, which was created by George Steers for a group headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. The first yachts were not designed and built in the modern sense, with merely a model used. Not until the later half of the 19th century did what was known as naval architecture come into being. Not until the 1920s did the application of the science of aerodynamics do for the craft of sails and rigging what it had already done for hulls.

Because most of all sailboats were individually custom-built, there came a need for handicapping boats previous to the one-design class boats were designed. Hence, a rating rule was decreed, which resulted in the International Rule, adopted in 1906 and amended in 1919. In modern times, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even keel with no handicapping at all. 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 belonged primarily for the royal and the affluent, cost was no object, and the size of boats increased, in both length and weight. The ascendancy and preference of smaller boats came 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 voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of small 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 favoured training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, during which steam was set to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were employed increasingly in leisure yachts. Bigger power yachts were progressed to a high element, and long-distance travel turned into a favourite pastime of the wealthy. The first power yachts were paddle-wheel boats; they then gave way to yachts powered by the wholly submerged screw or propeller kind of propulsion. Like naval and merchant yachts, auxiliaries carrying both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts with gasoline or diesel engines.

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

As bigger and more dependable internal-combustion engines were created, many big boats were using them for power. The establishment of the diesel engine, employing heavy oil for fuel, was furthered for World War I. During the decade after that, bigger power-yacht manufacture blossomed, reaching a climax in the Orion (1930) at 3,097 tons. From that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power craft declined from 1932, and the fashion after that was toward smaller, less expensive craft. After World War II, a lot of small naval boats were sold to private owners for conversion to yachts. By the late 20th century, yachting had become a globally popular activity enjoyed by thousands of yachtsmen who are actually manning and maintaining their own small recreational yachts. The amount of boats and yachtsmen is increasing 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 allocation of income and wealth. A proportional tax is one that puts the same relative requirement on each taxpayer—i.e., where tax liability and income move in equal proportion. A progressive tax is characterized by a larger than proportional increase in the tax onus in regard to the growth in income, and a regressive tax is recognised by a less than proportional growth in the comparable burden. Therefore, progressive taxes are regarded as taking away the lack of equality in income distribution, whereas regressive taxes may have the effect of an increase in these inequalities.

The taxes that are generally believed to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so in the upper-income categories—especially if a taxpayer is permitted to lessen his tax base by claiming deductions or by taking particular income elements from his taxable income. Proportional tax rates when applied to lower-income demographics would also be more progressive if such personal exemptions are declared.

Income measured over the course of a given period might not absolutely offer the most suitable measure of taxpaying requirements. For example, transitory rises in income can be saved, and during temporary declines in income a taxpayer could opt to finance consumption by reducing savings. Ergo, if taxation is regarded along with “permanent income,” it will be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (excepting luxuries) are mostly regressive, because the share of own income consumed or spent on a specific good declines as the rate of personal income grows. Poll taxes (also called head taxes), calculated as a set amount per capita, obviously are regressive.

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

In assessing the economic effects of taxation, it is necessary to differentiate between varied ideas of tax rates. The statutory rates include those dictated in legislation; usually these are marginal rates, but sometimes they are mean rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income rises by one dollar. Therefore, if tax liability rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates should consider provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated within the statutory rates. Since marginal rates signify how after-tax income changes in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applicable to income from business and capital, as it may be reliant on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the percentage of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally increase with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households can dwarf these effects, allowing regressivity, as shown by average tax rates that lessen as income grows.

The Development of Data Projectors

The LCDs utilised for projection systems are most often small reflective or transmissive panels illuminated by a bright arc lamp source. A number of lenses expands the reflected or transmitted image then casts it onto the screen. For front-projection systems the LCD is placed on the same side of the screen as the viewer, but in rear-projection systems the screen is illuminated from behind. Projectors of more expense and capability may have three separated LCD panels, casting separate red, green, and blue images that mesh to create a coloured image on the screen.

The growing desire for visual presentations has granted a special emphasis on the switching speed of liquid crystals. This has led to the invention of objects utilizing smectic liquid crystals, certain types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. With it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible turn up of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, similar to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. So, 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 therefore reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been commercialized for large passive-matrix presentations, but their cost and complexity has stopped them from enjoying any particular movement 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 quick reaction allows them to be utilised in time-sequential colour systems, in which expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast pulsing (about 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods and then to a nontransmissive state for the blue period, with the upshot 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 forms, the chair may be paramount. While most of the other pieces (save the bed) are created to support objects, the chair supports a human form. The term chair must be viewed here in the largest sense, from stool to throne to further pieces for example a bench and sofa, which might be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinguished.

The social history of the chair is as stimulating as its history as a creative art. The chair is not only a physical support and aesthetic creation; it was historically a symbol of social place. In the past royal courts there were social connotations between being led to a chair with arms, sitting on a chair with a back but no arms, or having to cope with a stool. During the last century, a director’s and manager’s chair has risen an identifier of superior dignity, as well as in democratic parliaments the speaker sits on an elevated platform.

As a furniture form, the chair is used for a variety of various purposes. There are chairs structured to suit man’s age and physical abilities (the high chair, the wheelchair) and to show his position in society (the executive chair, the throne). Since past days there were chairs used for birthing (birth chairs); from 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. We can make chairs that can be folded, chairs on wheels, and chairs on runners.

Contemporary lifestyle has demanded particular chairs for automobiles and aircraft. Every one of these chair forms have evolved to match to different human needs. From its significant association with man, the chair appears to its full purpose only when utilised. Although it doesn’t make any difference to one’s appreciation of a cupboard or a set of drawers whether there might be anything inside or not, a chair is really seen best and judged best with a person utilising it, for chair and sitter suit the other. Thus the different limbs of a chair are named corresponding to the elements of a human shape: arms, legs, feet, back, and seat.

Because the basic work of your chair is to support the human body, its value is evaluated primarily by how fully it does measure up to this practical purpose. Within the build of a chair, the chair maker is restricted under the static regulations and principal measurements. Through these limits, however, the chair creator has large freedom.

The history of the chair lasts over an era of several thousand years. There is evidence of cultures that have created unique chair shapes, expressive of the leading endeavour in the arenas of craft and aesthetics. In such civilisations, individual 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 objects of expert design, are today a finding from tomb findings. The first one of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs structured similar to those of a particular animal, a curved seat, and with a sloping back supported from vertical stretchers. In this way a solid triangular form was crafted. There seems to be no particular change from the construction of Egyptian thrones and chairs for regular non-royals. The main variation existed in the intricacy of its ornamentation, in the choice of more valuable inlays. The Egyptian folding stool probably was designed as an easily carried seat for army. As a camp stool this type stayed around during much later points. But the stool then was created for the use of a ceremonial seat, its mechanical role as a folding stool neglected or forgotten. This can from today be seen, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but aren’t able to be folded because the seats were formed out of wood. The simplistic build of the folding stool, being of two frames that rotate on metal bolts and support a seat of leather or fabric set between them, is seen but some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this kind is the folding stool, crafted out of ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is recognised not as any ancient object still around but seen in a trove of pictorial objects. The most well known is the klismos posited on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, only two of which would be seen. These unusual legs were understood to be executed of bent wood and were in that case needed to bear huge pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore extremely strong and were plainly pointed out.

The Romans embued the Greek designs; existing statues of seated Romans display examples of a thicker and are a kind of crudely constructed klismos. Both kinds, the light and the heavy, were popularised within the Classicist epoch. The klismos style can be evidenced in French Empire chairs, in English Regency, and in particular types of marked uniqueness within Denmark and Sweden during 1800.

China
The past of the chair in China isn’t able to be traced as far back as the history of the chair in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed serial of images and works of art was preserved, with images of the interiors and exterior of Chinese buildings and the furniture. Another preservation from the 16th century are a number of chairs made of wood or lacquered wood, that show an intriguing similarity to representations of ancient chairs.

As in Egypt, there were two fundamental chair forms in China: a chair having four legs and a folding stool. That chair can be found both with or without arms however never missing the square seat and straight stiles (vertical side supports) to firm the back. In one design, it has been seen, the stiles are delicately curved above the arms to sit right with the shape of the S-shaped back splat (the centre upright of a back). All three areas are mortised into the yoke-like top rail. Although the innovation of the Chinese back splat then had an inspiration for English chairs in the Queen Anne period, wooden pieces that just to a particular extent reinforce corner joints (and then were loose to top it off) are an element signatory to Chinese chairs. The four legs sit through the seat frame, which stops around the rounded staves. Each member is round in section or have rounded edges—references perchance to the bamboo tradition. The seat is not pleasant and may have a plaited texture. These chairs required the sitter to hold themselves stiff and upright; for when too much weight is forced on the back, the chair has a habit of falling over. In patriarchal Chinese houses of this epoch armchairs presumably were only for the senior members of the family, for they were respected greatly.

The Chinese folding stool is presumed to have travelled to China from the West. It is akin much from the Egyptian or Scandinavian folding stools, but it has a difference in that the top rail is intricately joined to the two legs of the stool by using a curved member, which is often possessing metal mounts. From a Western perspective the overall effect of both furniture items is stylized. The manufacture and decorative issues are combined in a manner that is both naïve and refined. The piecemeal appearance is an upshot of the fact that the individual members do not look to have been fixed by either glue or screws, but are mortised on one another and fixed in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its name on the chair. Works of art show a style of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to produce a pattern of little pads. The front board and a related board from the back could be folded after unscrewing some small iron hooks. Thus the chair was a portable piece of furniture when traveling which, in the same period, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is found in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair is also made in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not determined that the form actually was instigated in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in considerable amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is an entire row of these chairs lined up by a wall. The design asserts itself by its elegant proportions and expensive upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, as developed in Paris around 1750—disseminated over most of Europe and was imitated or copied into the mid-20th century. The design owes this popularity to a combination of comfort and charm. The seat adheres to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of relatively thick dimensions; but all members are deeply molded, all extraneous wood has been sanded away, and more expensive items can be further embellished with special delicate and decorative woodwork. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all the upholstery on the seat, back, and armrests; crosshatched cane is sometimes used in place of upholstery.

English chairs from the 18th century were more open in design than the French. The French preference for stylistic uniformity, which came from the premier circles in Paris and Versailles through 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 well-known 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, suggest that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping provides the information from which accounts are made but is a distinct process, prerequisite to accounting.

Essentially, bookkeeping finds two parts of information: (1) the current value, or equity, of a business and (2) changes in value—profit or loss—taking position in the entity over a singular period.

Management officials, investors, and credit grantors all need to have this information: management in order to interpret the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to understand the results of business operations and make decisions for buying, holding, and selling securities; and credit grantors to regard the financial statements of an enterprise in assessing whether to accept a loan.

Bits and pieces of financial and numerical charts have been seen for almost every state with a commercial background. Records of commercial contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The two-entry manner of bookkeeping came with the progression of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were created during the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a paramount factor. The past of bookkeeping, in fact, reflects closely the ancestry of commerce, industry, and government and, in some part, assisted in shaping it. The international revolution of industrial and commercial activity needed more cosmopolitan decision-making procedures, which in its turn needed more sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government regulation became more significant and resulted in even greater need for information; enterprises had to have available information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the demand for bookkeeping for their own inner operations became larger.

While bookkeeping methodology can be rather multifaceted, it is all based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger should have the information of individual accounts. The daily records from the journals are written in the ledgers.

Every month, generally, an income statement and a balance sheet are prepared from the trial balance posted out of the ledger. The duty of the income statement or profit-and-loss statement is to present an analysis of those changes that took place in the ownership equity resulting due to the events of the period. The balance sheet gives the financial condition of the business at a particular point in time 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.
