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

The common question that is asked when looking for a new projector for the home, office, or classroom is: should I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and different models available, it can be overwhelming for customers to make a decision between the two technologies. The simple fact of the matter is that LCD projectors have far superior image quality and colour accuracy. The next paragraph explains why DLP projectors struggle with bringing up an equal grade of image quality.

Think of a set of blinds in your home on your bedroom window. By a twist of a rod you can have the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector works. Each pixel operates like its own shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the content reaches your screen is extremely significant to 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 different LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then combined in a glass prism to send the projector image. Something important to remember about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector works is vastly different and even the produced image comes out is not the same. With DLP, white light from the lamp is sent through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to 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 displayed in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into a complete image. Using LCD projectors, all colours are available all the time to create the top level of brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some designers have put a white segment for the colour wheel to improve brightness overall, but this further detracts from colour accuracy.

I hear in forums all the time that DLP gives a higher contrast ratio and as such 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 machine is capable of. DLP projectors do provide high contrast specifications compared to many LCD projectors. At a glance, this appears to be a plus, however, in the real world, the true black level is determined by the ambient light in the room while the projector is being used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to bring to life includes moving images, DLP projection technology also creates image imperfections, 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 between the time red, blue and green colours are projected. LCD projectors do not have this problem because the colours are processed simultaneously. DLP developers have formed 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the cost of these projectors make them not practical for many businesses and consumers.

Another point of difference between LCD and DLP is how they match the balance for the refractive qualities of light. Remember back to high school science, and recall how the different colours of light refract different amounts when passing through the same lens. The downside with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are different and refract light differently. Generally with a DLP projector, a spill of yellow colour will appear above and some extra blue will show below something as simple as a straight black line. In manufacturing LCD projectors can be adjusted to minimize these effects on the projected image, because each colour is refracted on separate LCD panels.

The sole true plus (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant to portability and cannot be traded off against the image advantages of LCD projectors. If resulting picture quality is important to you, then the answer is no-brainer. Take an LCD projector! LCD projectors will always show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the first yacht was a pleasure craft used mostly by royalty and secondly by the burghers in the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private games. English yachting began with King Charles II of England during his exile in the Low Countries. On his return 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, reigned 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting became popular among the wealthy and nobility, but after that point the fashion 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 boats was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, by joining with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered manner on the Thames around 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 following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been started 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 yachting. The club at Cowes became the Royal Yachting Club, also at the ascension of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing races for great bets were held, and the social life was splendid. Ultimately Royal Yachting Club boats grew in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English held power. Sailing was mostly for fun and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a minimum of luxury and elegance for the later yachts in those waters from the late 19th century. The first persisting American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The craft of large yachts was initially largely put upon by the success of America, which was drawn by George Steers for a syndicate headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its victory at Cowes in 1851. Early yachts were not designed and built in a contemporary sense, with just a model used. Not until the later half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the application of the research of aerodynamics do for the design of sails and rigging what such science had previously done for hulls.

Because nearly all sailboats had to be individually manufactured, there arose a desire for handicapping boats previous to the one-design class boats were made. Therefore, a rating rule was decreed, which is found in the International Rule, adopted in 1906 and edited in 1919. In the present day, one of the most rapidly blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to standard specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even par with no handicapping required. A perfect example is the generic International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

So long as yachting was an activity largely for the aristocracy and the wealthy, expense was no object, and the size of boats developed, in both length and weight. The ascendancy and popularity of smaller craft came in the second 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 journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of small craft. Thereafter in the 20th century, particularly after World War II, smaller racing and leisure yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, in which steam was set to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were increasingly used in personal craft. Large power yachts were progressed to a high degree, and long-distance travel turned into a preferred occupation of the rich. The first power yachts were paddle-wheel boats; those then made way to yachts powered by the fully submerged screw or propeller type of propulsion. As well as naval and merchant vessels, auxiliaries possessing both sail and power were the yacht fashion for a number of years. By the second half of the 20th century, several yachts were still auxiliaries, but the large part were exclusively power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the manufacture of bigger steam yachts. Conspicuous within these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was manned 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 saw active service in World War II.

As bigger and more reliable internal-combustion engines were developed, many large yachts began using them for power. The creation of the diesel engine, with heavy oil for fuel, advanced from World War I. During the decade after that, big power-yacht manufacture grew, climaxing in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of bigger power yachts declined from 1932, and the trend thereafter was in preference of smaller, less expensive boats. From World War II, a lot of small naval craft were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally popular competition enjoyed by thousands of yachtsmen personally owning and keeping their own small leisure craft. The popularity of craft and yachtsmen is increasing steadily, not only in the traditional locations along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the distribution of income and wealth. A proportional tax is the kind of tax that impinges the same relative liability on every taxpayer—i.e., in the case where tax liability and income move in the same scale. A progressive tax is characterized by a greater than proportional rise in the tax burden relative to the rise in income, and a regressive tax is characterizable by a less than proportional increase in the relative liability. Hence, progressive taxes are regarded as fighting inequity in income distribution, while regressive taxes are seen to 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 nominally progressive, however, can become less so for the upper-income class—particularly if a taxpayer is allowed to reduce his tax base by nominating deductions or by excluding certain income elements from his taxable income. Proportional tax rates when applied to lower-income demographics will also be more progressive if personal exemptions are declared.

Income measured over the course of a given period might not definitely give the most suitable measure of taxpaying status. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may opt to pay for consumption by decreasing savings. Ergo, if taxation is compared along with “permanent income,” it would be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are mostly regressive, because the portion of own income consumed or spent for specific goods declines as the amount of personal income rises. Poll taxes (also called head taxes), calculated as a standard amount per capita, obviously are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends essentially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In analysing the economic effect of taxation, it is necessary to differentiate between various points of tax rates. The statutory rates will include those nominated in the law; usually these are marginal rates, but for some cases they are mean rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income rises by one dollar. Hence, if tax liability grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations often contain graduated marginal rates—i.e., rates that rise as income increases. Heavy analysis of marginal tax rates need to take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than specified in the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for considering incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applied to income from business and capital, because it may rely on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates determine the portion of total income that is taken in taxation. The pattern of average rates is the one that is in consideration for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally rise with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households may dampen these effects, forcing regressivity, as signified by average tax rates that fall as income grows.

The Development of Data Projectors

The LCDs utilised for projection systems are typically small reflective or transmissive panels lit by a powerful arc lamp source. A line of lenses expands the reflected or transmitted image and then displays it on the screen. In front-projection systems the LCD is placed on the side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of more expense and capability may have three separate LCD panels, reflecting separate red, green, and blue images that blend to form a coloured picture on the screen.

The increase in desire for film presentations has had a growth in emphasis on the switching speed of liquid crystals. This has demanded the creation of devices employing smectic liquid crystals, certain kinds of which possess a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most complex smectic device. In it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are slanted, as shown in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible result of the optical activity and the angle of the molecules is the appearance 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 in 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 consequential change in optical properties can effect a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been produced for large passive-matrix displays, but their expensiveness and complexity has stopped them from making any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as parts in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be employed in time-sequential colour systems, in which dear colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid pace (about 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and to a nontransmissive state for the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture items, the chair may be of the most importance. While most of the other forms (save the bed) are devised to support objects, the chair supports your human form. The term chair is regarded here in the general sense, from stool to throne to developed types for example a bench or sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinuishable.

The social history of the chair is as exciting as its history as a creative art. The chair is not just a physical support and/or aesthetic piece of art; it was also a symbol of social place. At the old royal courts there were important differences between having a chair with arms, on a chair with a back but without arms, and having to use a stool. In the last century, the director’s or manager’s chair has developed an indicator of superior standing, like in democratic government debate the speaker sits on a raised level.

As its furniture construction, the chair is employed for a range of different makes. There are chairs manufactured to match man’s age and physical form (the high chair, the wheelchair) and to connotate his rank in society (the executive chair, the throne). In historical days there were chairs to be born in (birth chairs); in the 20th century, there have been chairs used for ending life (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 make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated special chairs for automobiles and aircraft. All of these chair types have changed to conform to changing human needs. Because of its unique link with man, the chair comes to its full significance only when in employ. While it doesn’t make a difference to one’s appreciation of a cupboard or a chest of drawers whether there are things inside or not, a chair is really seen and regarded best with a person sitting on it, because chair and sitter require one another. Thus the individual elements of the chair are given labels as the limbs of a human parts: arms, legs, feet, back, and seat.

Because the primary work of a chair is to support the human body, its credit is tested firstly for how completely it does fulfill this practical use. In the construction of a chair, the carpenter is limited for certain static regulations and principal measurements. Under these limitations, however, the chair creator has extensive freedom.

The history of the chair lasts over an epoch of several thousand years. There were peoples that had made unique chair forms, as expressive of the foremost endeavour in the industries of craft and aesthetics. Within these such peoples, a note 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of expert craft, were a finding from tomb findings. First of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair had four legs formed as akin to those of a designated animal, a curved seat, and a sloping back supported above vertical stretchers. From this design a durable triangular form was obtained. There was to all appearances no significant variation from the construction of Egyptian thrones and chairs for ordinary non-royals. The simple variation existed in the complex ornamentation, in the particulars of more costly inlays. The Egyptian folding stool likely was designed to be an easily portable seat for officers. As a camp stool this chair existed during much later days. But the stool also then was created as the task of a ceremonial seat, its mechanical history as a folding stool neglected or forgotten. This can from evidence be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the construction of folding stools but are not able to be folded because the seats were made out of wood. The plain build of the folding stool, made of two frames that cycle on metal bolts and support a seat of leather or fabric secured between them, appeared at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this type is the folding stool, crafted out of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not from any ancient item still extant but as found in a trove of pictorial evidence. The most recognisable is the klismos placed on the Hegeso Stele at the Dipylon burial ground just out of Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those were seen. These strange legs were considered to be executed from bent wood and were as such bore a large amount of pressure from the weight of the sitter. The joints joining the legs to the frame of the seat are therefore extremely strong and were overtly pointed out.

The Romans adopted the Greek design; evidence of casts of seated Romans display evidence of a thicker and apparently rather less delicately built klismos. Both styles, light or heavy, were revived within the Classicist time. The klismos chair is seen in French Empire furniture, in English Regency, and in some special kinds of notable originality in Denmark and Sweden during 1800.

China
The history of the chair in China cannot be tracked as long as the ancestry of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an undamaged collection of images and paintings has been preserved, showing the inside and outer parts of Chinese households and the furniture. Also preserved since the 16th century are some chairs made of wood or lacquered wood, that display an astonishing resemblance to styles of past chairs.

As was the case in Egypt, there existed two major chair designs in China: a chair having four legs and a folding stool. This four-legged chair has been found both with or without arms although never missing a square seat and straight stiles (standing side supports) to give support to the back. In one form, though, the stiles could be slightly curved by the arms for the purpose of suit the angle of the S-shaped back splat (the main upright of a chairback). The three areas were mortised in the yoke-like top rail. While the style of the back splat exercised an inspiration for English chairs of the Queen Anne period, wooden sections that would only to a restricted extent support corner joints (and then were loose as a result) represent a design solely to Chinese chairs. The four legs pass through the seat frame, which closes about the rounded staves. All the members are round in section or is given rounded edges—acknowledging maybe to the bamboo tradition. The seat is unpleasant to sit in and occasionally had a plaited texture. These chairs demanded of the sitter to be stiff and upright; when too much pressure is forced on the back, the chair has a habit of collapsing. In patriarchal Chinese households of this period armchairs probably were reserved only for older individuals, for they were greatly respected.

The Chinese folding stool is thought to have travelled to China from the West. It does not differ 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 in a curved member, which is usually provided with metal mounts. From a Western understanding the resultant effect of these furniture items is stylized. The structure and aesthetic elements are combined in a manner that is both naïve and refined. The patchwork appearance is an outcome of the way that the individual parts do not appear to have been put together with either glue or screws, but were mortised onto one another and fixed in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its name on the chair. Works of art show a design 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 small pads. The front board and a similar board at the back could be folded after loosening some tiny iron hooks. Thus the chair was a portable piece of furniture in traveling which, at the same era, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair can be found in engravings of interiors of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair may also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not believed that the innovation actually was born in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of thin dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was crafted in impressive numbers, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of such chairs lined up along a wall. The design asserts itself by its harmonious proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that was, to say, as progressed in Paris around 1750—spread through most of Europe and has been imitated or copied in the mid-20th century. The style owes this popularity to a combination of comfort and delicacy. The seat suits to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back cover all the joints, which are solidly constructed on craftsmanlike practices even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof employ wood of relatively thick density; but all members are deeply molded, all extraneous wood has been removed, and more upmarket items might be further embellished with intricately delicate and decorative woodwork. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all the upholstery on the seat, back, and armrests; cane is in some cases used rather than upholstery.

English chairs from the 18th century were more variable in form than the French. The French preference for stylistic uniformity, which lead from the premier circles in Paris and Versailles throughout most of France and found favour 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 reknowned 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 operation of a business. Bookkeeping gives the numbers from which accounts are written but is a different process, prerequisite to accounting.

Fundamentally, bookkeeping finds two kinds of information: (1) the current value, or equity, of a business and (2) any changes in value—profit or loss—taking placement in the enterprise during a particular period of time.

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

Evidence of financial and numerical record charts are found for just about every nation with a commercial backbone. Records of business contracts were uncovered in the ruins of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The two-entry process of bookkeeping came with the furthering of the business republics of Italy, and tutorial manuals for bookkeeping were produced in the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial bookkeeping a paramount factor. The past of bookkeeping, in fact, closely reflects the past of commerce, industry, and government and, in part, helped to form it. The global market of industrial and commercial activity called for more professional decision-making methodology, which in its turn called for higher sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government regulation became more detailed and resulted in greater need for information; businesses had to provide information to support 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 own inner operations became larger.

Although bookkeeping procedures can be rather detailed, all are based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, etcetera), and the ledger must have the record of individual accounts. The daily records from the journals are written in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are prepared from the trial balance posted from the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of the changes that have taken place in the business equity due to the operations of the period. The balance sheet provides the financial situation of the company at any particular point in time in terms of 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 yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

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

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

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

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

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