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

The most typical question asked when looking for a new projector for the home, office, or classroom is: would I take an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most popular projector imaging technologies. With so many brands and different models available, it can be overwhelming for consumers to choose between both technologies. The fact is that LCD projectors have superior image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with projecting a similar level of image quality.

Visualise a set of blinds in your home on your bedroom window. With the twist of a rod you can have the shutters open or closed, depending on whether you want to let light in or not. And that is exactly how an LCD projector works. Each pixel operates like a unique shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector turns on to when the image reaches your screen is vitally important in regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating it into red, blue and green components, by three mirrors which transfer the coloured light to 3 separate LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. An important point to remember about LCD projectors is that all three colours are directed onto your projected surface all at once. The way a DLP projector functions is vastly different and even the produced image shows up is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming an image casts a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to create the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into the total image. With LCD projectors, all colours are available all the time to offer top brightness and superb colour accuracy. In DLP, only one colour is available at any given time, resulting in lower colour brightness and accuracy. Some DLP developers have added a white segment in the colour wheel to improve brightness generally, but this also lessens colour accuracy.

I see in forums all the time that DLP offers a higher contrast ratio and thus must be superior quality. For those who don’t 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 capable of. DLP projectors do provide high contrast specifications when compared to most LCD projectors. At one glance, this must be a benefit, however, in reality, the true black level is determined by the ambient light in the room in which the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you plan to project needs moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most often seen artifact that a DLP projector forms with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are projected. LCD projectors do not have this problem because all the colours are sent at the same time. DLP developers have come up with 3DLP solutions using 3 chips to fix the colour break up error, but the cost of these projectors make them almost impossible for many businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and remember how the different colours of light refract varied amounts when projected through the same lens. The downside with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are different and refract light in different ways. Generally with a DLP projector, some yellow colour will appear above and some blue will appear below an image as simple as a straight black line. In manufacturing LCD projectors can be adjusted to remove these effects on the projected image, because each colour is processed on a separate LCD panels.

The one actual advantage (excluding price) with choosing a DLP projector is its smaller total size and weight. However, this is only relevant with regard to transporting the device and cannot be traded off against the image superiority of LCD projectors. If overall picture quality is vital to you, then the choice is a no-brainer. Go with an LCD projector! LCD projectors will always show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the initial yacht became a pleasure craft used mostly by royalty and secondly by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English monarchy in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), made additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting rose as classy among the wealthy and nobility, but after that time the habit did not last.

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

Yacht racing began in some ordered method on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been initiated at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British racing. The society at Cowes became the Royal Yachting Club, likewise at the rise of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing races for high stakes were held, and the society life was wonderful. Ultimately Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English had dominance. Sailing was mostly for fun and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised 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 enduring American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The style of large yachts was originally greatly put upon by the win of America, which was designed 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 success at Cowes in 1851. The first yachts were not designed and built in a contemporary sense, with only a model being used. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the structure of sails and rigging what such study had previously done for hulls.

Because most of all sailboats had been individually built, there came a requirement for handicapping boats previous to the one-design class boats were made. Hence, a rating rule was written, which ended up in the International Rule, taken on in 1906 and edited in 1919. In modern times, one of the most rapidly growing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing those boats can be done on an even basis with no handicapping at all. A perfect example is the uniform International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

As long as yachting was an activity largely for the aristocracy and the rich, money was no issue, and the size of boats grew, in both length and weight. The rise and desire of smaller craft occurred in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of smaller yachts. Later in the 20th century, for the larger part after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, when steam began to emulate sail power in market vessels, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure yachts. Bigger power yachts were developed to a high degree, and long-distance cruising became a preferred occupation of the wealthy. The early power yachts were paddle-wheel boats; these then gave way to those powered by the fully 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 fashion for a number of years. By the latter half of the 20th century, many yachts were still auxiliaries, but the majority were solely power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a push in the construction of bigger steam yachts. Notably among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service for World War II.

As more sizeable and more dependable internal-combustion engines were produced, many big craft began using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed from World War I. In the decade following, large power-yacht building flourished, hitting a climax in the Orion (1930) at 3,097 tons. In that period the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power craft fell away after 1932, and the trend from then was toward smaller, less costly craft. From World War II, a lot of small naval craft were bought by private owners for conversion to yachts. By the late 20th century, yachting is a widespread beloved sport enjoyed by thousands of yachtsmen personally sailing and maintaining their own small recreational yachts. The popularity of yachts and owners is increasing steadily, not only in the traditional places along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the distribution of income and wealth. A proportional tax is the kind that imposes the same relative onus on all taxpayers—i.e., where tax liability and income increase in the same scale. A progressive tax is characterized by a more than proportional rise in the tax burden in relation to the growth in income, and a regressive tax is characterizable by a less than proportional increase in the relative onus. Therefore, progressive taxes are thought of as reducing the lack of equality in income distribution, while regressive taxes are believed to cause an increase in these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so for the upper-income group—particularly if a taxpayer is allowed to lessen his tax base by declaring deductions or by removing some particular income components from his taxable income. Proportional tax rates when applied to lower-income groups will also be more progressive if personal exemptions are claimed.

Income measured over the period of a year may not absolutely provide the best measure of taxpaying status. For example, transitory growth in income could be saved, and within temporary declines in income a taxpayer could select to finance consumption by decreasing savings. Thus, if taxation is made comparable along with “permanent income,” it will be less regressive (or more progressive) than when held in comparison with annual income.

Sales taxes and excises (except luxuries) are generally regressive, because the dissemination of one’s income consumed or spent for specific goods declines as the amount of personal income increases. Poll taxes (aka head taxes), nominated as a flat amount per capita, clearly are regressive.

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

In analysing the economic purposes of taxation, it is essential to differentiate between differing points of tax rates. The statutory rates will include those specified in legislature; often these are marginal rates, but sometimes they are mean rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income grows by one dollar. Hence, if tax burden rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature usually contain graduated marginal rates—i.e., rates that increase as income increases. Structured analysis of marginal tax rates must regard provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than nominated within the statutory rates. Since marginal rates display how after-tax income is changed in response to changes in before-tax income, they are the necessary ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate applicable to income from business and capital, since it may be reliant on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates show the part 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 commonly increase with income, both because personal allowances are granted for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households can dwarf these effects, producing regressivity, as displayed by average tax rates that decline as income increases.

The Development of Data Projectors

The LCDs used for projection systems are most often small reflective or transmissive panels lit up by a forceful arc lamp source. A line of lenses expands the reflected or transmitted image then sends it on the screen. With front-projection systems the LCD is set on the same area of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of higher cost and capability may be found with three discrete LCD panels, reflecting separate red, green, and blue images that mesh to reflect a coloured display on the screen.

The growing need for film displays has granted a growing emphasis on the switching speed of liquid crystals. This has required the manufacture of devices employing smectic liquid crystals, some types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most sophisticated smectic device. In it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are on a slant, as displayed in the figure. The host liquid crystal contains optically active molecules, and a slight turn up of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Therefore, there must be a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly attracted 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 in so doing reverse the tilt direction of the molecules. The resultant 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 marketed for bigger passive-matrix displays, but their expensiveness and complexity has stopped them from making any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some possibility for use as aspects in projection systems or as viewfinders in digital cameras. Their speedy reaction allows them to be used in time-sequential colour systems, in which high cost colour filters are replaced with a coloured backlight that flashes red, green, and blue in quick pace (about 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state for the red and green periods then to a nontransmissive state in the blue period, having the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture forms, the chair might be the most important. While the majority of other forms (save for the bed) are created to support objects, the chair supports a human form. The term chair must be said here in the most open sense, from stool to throne to developed pieces including the bench or sofa, which can be regarded 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 stimulating as its history as an art and craft. The chair is not merely a physical support or aesthetic creation; it was historically a signifier of social placement. Within the historical royal courts there were plain connotations between having a chair with arms, on a chair with a back but no arms, or worse having to sit on a stool. In the 20th century, the director’s and/or manager’s chair has been seen as a signifier of superior dignity, as well as in democratic parliaments the speaker sits on an elevated floor.

As a furniture construction, the chair is utilised for a range of different forms. There are chairs structured 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). Since past times there were chairs for birthing (birth chairs); in the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has derived unique chairs for use in automobiles and aircraft. Each and every one of these chair types has been perfected to suit to growing human needs. From its significant connection with man, the chair lives to its full advantage only when in employ. Although it isn’t relevant to one’s appreciation of a cupboard or a dresser drawers if there are items inside or not, a chair is understood best and tested with a person sitting on it, because chair and sitter complement one another. Thus the various elements of a chair are given labels corresponding to the limbs of a human shape: arms, legs, feet, back, and seat.

Because the elementary role of the chair is to support your body, its worth is evaluated firstly for how completely it does fulfill this practical use. In the structure of the chair, the chair maker is restricted by some static legislation and principal measurements. In these limits, however, the chair designer has great freedom.

The history of the chair was dates of several thousand years. There existed cultures that had significant chair types, expressive of the premier work in the arenas of technique and design. Among those cultures, special 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 result of careful design, were a finding from discoveries made in tombs. First of these is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs structured not unlike those of some animal, a curved seat, and leading to a sloping back supported over vertical stretchers. From this design a durable triangular design was created. There was from our view no particular change between the construction of Egyptian thrones and chairs for typical people. The simple variation exists in the level of ornamentation, in the choice of more costly inlays. The Egyptian folding stool most probably was made to be an easily carried seat for soldiers. As a camp stool that kind stayed around for much later periods. But the stool also was designed as the role of a ceremonial seat, its original function as a folding stool ignored or forgotten. This can from evidence be noted, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were in the form of folding stools but aren’t able to be folded because the seats were made with wood. The plain structure of the folding stool, being of two frames that turn on metal bolts and have a seat of leather or fabric fastened between them, appeared again but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of those is the folding stool, from ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is known not with any ancient fossil still around but as seen from a wealth of pictorial objects. The best known is the klismos placed on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those could be shown. These creative legs were understood to have been executed in bent wood and were therefore had extreme pressure under the weight of the sitter. The joints holding the legs to the frame of the seat are therefore very stable and were clearly denoted.

The Romans borrowed from the Greek chair; existing models of seated Romans display chairs of a more heavyset and which appear to be a slightly less intricately crafted klismos. Both features, light or heavy, were revived during the Classicist time. The klismos style is known in French Empire furniture, in English Regency, and in particular forms of notable originality within Denmark and Sweden circa 1800.

China
The past of the chair in China cannot be charted as well as chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken folio of sketches and paintings was kept safe, showing the insides and exterior of Chinese houses and the designs of furniture. Preserved also from the 16th century are a number of chairs of wood or lacquered wood, that bear an intriguing similarity to styles of ancient chairs.

Just like in Egypt, two fundamental chair forms existed in China: a chair of four legs and a folding stool. That chair has been designed both with and without arms although never missing a square seat and straight stiles (straight side supports) to give support to the back. In one image, it has been seen, the stiles were delicately curved by the arms for the purpose of fit the structure of the S-shaped back splat (the central upright of a back). Together, the three areas are mortised onto the yoke-like top rail. While the innovation of the back splat had a foundation for English chairs within the Queen Anne period, wooden sections that could only to a restricted ability reinforce corner joints (as well as being loose additionally) represent a design solely to Chinese chairs. The four legs sit through the seat frame, which ends over the rounded staves. Each member is round in section or has rounded edges—acknowledging maybe to the bamboo tradition. The seat is unpleasant to sit in and had on occasion a plaited form. These chairs needed the sitter to remain stiff and upright; if too much pressure is exerted on the back, the chair has a tendency to fall. In patriarchal Chinese homes of this epoch armchairs likely were only for senior persons in the family, for they were held in great respect.

The Chinese folding stool is thought to have taken to China from the West. It does not vary much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is intricately held to the two legs of the stool in a curved member, which is often seen with metal mounts. From a Western viewpoint the resultant effect of both these furniture forms is stylized. The manufacture and decorative elements are combined in a way that is all at once naïve and refined. The piecemeal appearance is a result of the manner that the individual members do not appear to have been held together by means of either glue or screws, but had been mortised on one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its name on the chair. Artworks show a kind of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of little pads. The front board and a related board in the back could be folded after unscrewing some tiny iron hooks. In this way the chair was a readily portable piece of furniture when traveling which, at the same time, possessed the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is seen in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair might also be made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the design actually started in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was produced in impressive numbers, as can be seen from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up by a wall. The style asserts itself with its harmonious proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as developed in Paris around 1750—conquered most of Europe and was imitated or copied during the mid-20th century. The design owes such popularity to a combination of leisure and charm. The seat conforms to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions are found between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of rather thick density; but every member is deeply molded, all superfluous wood has been sanded away, and finer examples might be further embellished with intricately delicate and decorative carvings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

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

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

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

In cheaper 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 recording of the money values of the operation of a business. Bookkeeping gives the details from which accounts are written but is a separate process, preliminary to accounting.

Basically, bookkeeping records two types of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking position in the entity within a single period.

Management officials, investors, and credit grantors all require this kind of information: management in order to interpret the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to assess the upshot of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of a business in finding whether to give a loan.

Bits and pieces of financial and numerical recordkeeping are seen for almost every civilization with a commercial background. Records of business contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The double-entry way of bookkeeping came with the furthering of the business republics of Italy, and tutorial manuals for bookkeeping were created during the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial books a requirement. The past of bookkeeping, in fact, resembles the history of commerce, industry, and government and, partially, helped shaping it. The worldwide expansion of industrial and commercial activity called for greater cosmopolitan decision-making methodology, which in its turn required better sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more important and resulted in increased need for information; enterprises had to have information available to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the demand for bookkeeping for their own operations became higher.

While bookkeeping processes can be extremely complex, it is all based on two types of books employed in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so forth), and the ledger must have the information of individual accounts. The daily records in the journals are entered in the ledgers.

Every month, as a general rule, 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 those changes that happen in the entity equity due to the events of the period. The balance sheet shows the financial position of the entity at any particular date derived from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful 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.
