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

The most common question heard when purchasing a new projector for the home, office, or classroom is: should I get an LCD projector or a DLP projector? LCD, standing 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 types available, it can be overwhelming for consumers to pick between both technologies. Ultimately LCD projectors give far superior image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with projecting a comparable rate of image quality.

Think of a set of blinds in your home covering your bedroom window. With the twist of a rod you can have the shutters open or closed, depending on if you want to let light in or not. Such is exactly how an LCD projector functions. Each pixel works like a unique shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element works 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 content reaches your screen is absolutely significant with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting it into red, blue and green components, by three mirrors which send 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 form the projector image. Something important to know about LCD projectors is that all three colours are sent onto your projector screen simultaneously. The way a DLP projector operates is very different and even the way an image looks is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of forming an image casts a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to form the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then draw each coloured element of the image into the complete image. Using LCD projectors, all colours are available all the time to form the highest brightness and fantastic colour accuracy. In DLP, just one colour is available at any given time, and so causing lower colour brightness and accuracy. Some DLP manufacturers have added a white segment for the colour wheel to improve brightness generally, but this also lessens colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and therefore 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 technology is capable of. DLP projectors do possess high contrast specifications in comparison to many LCD projectors. At a glance, this must be an advantage, however, in the real world, the true black level is determined by the ambient light in the room while the projector is being utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to see includes moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because all colours are projected simultaneously. DLP builders have created 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price tag of these projectors make them not practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how various colours of light refract differing amounts when shone through the same lens. The downfall 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 obviously not the same and refract light in different ways. Often with a DLP projector, a superfluous yellow colour will come up above and some extra blue will be projected below an image as simple as a single black line. In manufacturing LCD projectors can be adjusted to reduce these effects on the projected image, as each colour is projected on its own LCD panels.

The isolated actual advantage (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant in regard to portability and needs to be traded off against the image superiority of LCD projectors. If the outcome of the picture quality is important to you, then the choice is no-brainer. Take an LCD projector! LCD projectors will constantly create bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the initial yacht was a pleasure craft used mostly by royalty and later by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting rose as popular with the rich and nobility, but after that period the fashion did not last.

The first yacht club in the British Isles, the Water Club, was formed at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, with much naval panoply and gravity. The closest thing to a race was the “chase,” for which 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 became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized fashion 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 the throne in 1820, it came to be called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been formed at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British racing. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing tests for large bids were held, and the club life was lovely. Ultimately Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English held control. Sailing was mostly for leisure and rose to its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first continuing American yacht organisation, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the latter half of the 19th century. The craft of large yachts was first largely put upon by the victory of America, which was created by George Steers for a syndicate led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. Early yachts were not designed and manufactured in today’s sense, with only a model used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the structure of sails and rigging what such study had already done for hulls.

Because almost all sailboats had to be individually custom-built, there was a need for handicapping boats previous to the one-design class boats were built. Hence, a rating rule was created, which is found in the International Rule, adopted in 1906 and edited in 1919. In modern times, one of the rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing those boats can be held on an even basis with no handicapping at all. A perfect example is the uniform International America’s Cup Class adopted for yachts in the 1992 America’s Cup race.

So long as yachting was done mostly for the aristocracy and the rich, money was no object, and the size of boats developed, in both length and weight. The promotion and preference of smaller boats came in the second half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of less sizeable craft. Following this in the 20th century, particularly after World War II, smaller racing and recreational yachts became more common, down to the dinghy, a favourite 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
Following the decade 1840–50, at which point steam began to emulate sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly used in pleasure vessels. Sizeable power yachts were developed to a high standard, and long-distance travel turned into a favoured pastime of the affluent. The early power yachts were paddle-wheel boats; those then made way to yachts powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant yachts, auxiliaries possessing both sail and power were the yacht archetype for many years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were only power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a push in the manufacture of more sizeable steam yachts. Conspicuous of these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of at least 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 saw active service for World War II.

As larger and more reliable internal-combustion engines were produced, many bigger yachts were using them for power. The establishment of the diesel engine, with heavy oil for fuel, was furthered from World War I. In the decade following, large power-yacht creation flourished, climaxing in the Orion (1930) at 3,097 tons. In that time the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power craft lessened in 1932, and the style from then was for smaller, less costly craft. Following World War II, lots of small naval craft were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a widespread popular competition enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small recreational yachts. The number of yachts and yachtsmen 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 are categorized by the impact they have on the placement of income and wealth. A proportional tax is a kind that puts the same relative liability on all taxpayers—i.e., in the case where tax liability and income increase in the same scale. A progressive tax is characterizable by a larger than proportional growth in the tax burden in regard to the increase in income, and a regressive tax is characterized by a less than proportional increase in the comparative onus. Therefore, progressive taxes are viewed as taking away the lack of equality in income distribution, while regressive taxes might increase these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, can become less so in the upper-income class—especially if a taxpayer is permitted to lower his tax base by claiming deductions or by taking some particular income parts from his taxable income. Proportional tax rates that are applied to lower-income groups could also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the course of a given period may not absolutely come up with the best measure of taxpaying status. For example, transitory increases in income might be saved, and during temporary declines in income a taxpayer may decide to provide for consumption by decreasing savings. So, if taxation is made comparable with “permanent income,” it should be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (with the exception of luxuries) are mostly regressive, because the dissemination of one’s income consumed or spent for specific goods declines as the amount of personal income is raised. Poll taxes (also called head taxes), levied as a set amount per capita, clearly are regressive.

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

In assessing the economic purpose of taxation, it is relevant to differentiate between varied ideas of tax rates. The statutory rates will include those specified in the law; generally these are marginal rates, but in some cases they are median rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income increases by one dollar. Therefore, if tax burden rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that increase as income grows. Heavy analysis of marginal tax rates are required to review 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 growth in income, the marginal rate is 20 percentage points higher than nominated by the statutory rates. Since marginal rates signify how after-tax income moves in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate to apply to income from business and capital, as it may rely on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the fraction of total income that is paid in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates usually rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received mostly by high-income households might dwarf these effects, producing regressivity, as indicated by average tax rates that lower as income increases.

The Development of Data Projectors

The LCDs built for projection systems are generally small reflective or transmissive panels lit by a powerful arc lamp source. A number of lenses magnifies the reflected or transmitted image and casts it onto a screen. For front-projection systems the LCD is set on the same side of the screen as the viewer, although in rear-projection systems the screen is lit from behind. Projectors of greater expense and performance may be found with three distinct LCD panels, forming separate red, green, and blue images that combine to reflect a coloured display on the screen.

The increase in requirement for video displays has put a particular emphasis on the switching speed of liquid crystals. This has required the creation of devices employing smectic liquid crystals, certain types of which give a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. With it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a subtle result of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. So, there must be a permanent charge separation through 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 right sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The respective change in optical properties can effect a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been produced for large passive-matrix displays, but their expense and complex nature has stopped them from creating any particular effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be used in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid succession (approx 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and then to a nontransmissive state in the blue period, with the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture pieces, the chair might be of the most importance. While the majority of other objects (apart from the bed) are intended to support objects, the chair supports our human form. The term chair must be said here in the most general sense, from stool to throne to complex chairs like a bench and sofa, which should be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly definitive.

The social history of the chair is as intriguing as its history as a creative craft. The chair is not just a physical support or an aesthetic piece; it historically is semiotic of social standing. At the historical royal courts there were plain connotations between being seated on a chair with arms, sitting on a chair with a back but without arms, or having to sit on a stool. During the recent century, the director’s or manager’s chair has been regarded as a signifier of superior rank, like in democratic parliaments the speaker sits on an elevated floor.

In a furniture form, the chair can be employed for a range of various models. There are chairs manufactured to suit man’s age and physical abilities (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). During historical times there were chairs for births (birth chairs); from the 20th century, there have been chairs used for ending life (the electric chair). We have 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.

Our contemporary lifestyle has designated new chairs in automobiles and aircraft. Each of these chair shapes has been changed to conform to changing human requirements. For its particular importance with man, the chair lives to its full purpose only when used. Though it does not make a difference to one’s appreciation of a cupboard or a dresser drawers whether there is anything inside or not, a chair is understood best and fairly regarded by a person utilising it, for chair and sitter require one another. Thus the individual areas of the chair were labeled corresponding to the parts of a human form: arms, legs, feet, back, and seat.

Because the obvious function of the chair is to support our human body, its credit is valued principally on how well it fulfills this practical use. In the manufacture of the chair, the builder is restricted under some static regulations and principal measurements. Under these limitations, however, the chair designer has awesome freedom.

The history of the chair lasted a period of several thousand years. There is evidence of cultures that had made iconic chair forms, seen of the highest work in the industries of craft and design. Within such societies, special 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 lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of masterful craft, are today known from tomb discoveries. First of these two is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs formed as akin to those of a chosen animal, a curved seat, with a sloping back supported above vertical stretchers. From this a durable triangular construction was made. There was to our understanding no noteworthy variation from the structure of Egyptian thrones and chairs for ordinary non-royals. The general variation lies in the kind of ornamentation, in the evidence of pricey inlays. The Egyptian folding stool in all likelihood was created for an easily carried seat for army soldiers. As a camp stool the type existed until much later periods. But the stool then was designed as the role of a ceremonial seat, its mechanical role as a folding stool ignored or forgotten. This can from evidence be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but are not able to be folded because the seats are created from wood. The simple build of the folding stool, made of two frames that cycle on metal bolts and have a seat of leather or fabric fastened between them, came up somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this form is the folding stool, made from ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is seen not from any ancient item still extant but found in a variety of pictorial material. The archetype is the klismos placed on the Hegeso Stele at the Dipylon burial place outside Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of which would be visible. These curving legs were likely to be crafted out of bent wood and were as such subjected to extreme pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat are therefore extremely strong and were plainly pointed out.

The Romans adopted the Greek designs; quite a few statues of seated Romans offer evidence of a more heavyset and apparently somewhat crudely designed klismos. Both types, light and heavy, were popularised in the Classicist epoch. The klismos design is seen in French Empire design, in English Regency, and in particular types of considerable individuality of Denmark and Sweden during 1800.

China
The history of the chair in China cannot be tracked as far back as the ancestry of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken series of sketches and artworks was kept safe, displaying the interiors and exteriors of Chinese buildings and their furniture. Preserved also since the 16th century are a number of chairs of wood or lacquered wood, that bear an amazing familiarity to designs of ancient chairs.

Just as in Egypt, there were two fundamental chair forms in China: a chair of four legs and a folding stool. This chair was designed both with or without arms although always with a square seat and straight stiles (vertical side supports) to give support to the back. In one kind, it must be said, the stiles had been delicately curved above the arms for the purpose of sit correctly with the form of the S-shaped back splat (the main upright of its back). The three areas are mortised into the yoke-like top rail. Though the design of the Chinese back splat had an influence on English chairs in the Queen Anne period, wooden pieces that merely to a restricted capability support corner joints (as well as being loose as a result) indicate an element solely to Chinese chairs. The four legs are set through the seat frame, which finishes about the rounded staves. All members are round in section or has rounded edges—an acknowledgement perhaps to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited bottom. These chairs required the sitter to hold themselves stiff and upright; for if too much pressure is placed on the back, the chair has a way of falling over. In patriarchal Chinese homes of this period armchairs presumably were only for elderly people in the family, for they were held in great respect.

The Chinese folding stool is understood to have travelled to China from the West. It does not differ much from the Egyptian and Scandinavian folding stools, but it has a variation in that the top rail is intricately held to the two legs of the stool by means of a curved member, which is more often than not provided with metal mounts. From a Western point of view the resultant effect of these two furniture designs is stylized. The construction and decoration parts are combined in a manner that is at the same time naïve and refined. The patchwork appearance is a result of the way that the individual items do not look to have been held together by either glue or screws, but have been mortised on one another and fixed in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its mark on the chair. Artworks display a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in the layers, stitched to produce a pattern of small pads. The front board and a corresponding board from the back could be folded after loosening some tiny iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, in the same era, gave the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is found in engravings of interiors of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this kind of chair might also be found in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not determined that the form actually was instigated in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in considerable quantities, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up by a wall. The design asserts itself with 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 style—that was, to say, as created in Paris around 1750—conquered most of Europe and has been imitated or copied in the mid-20th century. The style owes such popularity to a combination of relaxation and delicacy. The seat suits to the human body and grants 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 over the armrests. Smooth transitions are achieved between seat frame, legs, and back cover all the joints, which are constructed strongly on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of rather thick dimensions; but all the members are deeply molded, all extraneous wood has been sanded away, and more upmarket designs can be further embellished with highly delicate and decorative engraving. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all upholstery on the seat, back, and armrests; crosshatched cane is sometimes used as an alternative to upholstery.

English chairs from the 18th century were more differentiated in style than the French. The French manner for stylistic uniformity, which came from the aristocratic circles in Paris and Versailles over most of France and won favour 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 popularised and was widely distributed throughout the world.

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

In cheaper products of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

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

Essentially, bookkeeping provides two kinds of information: (1) the current value, or equity, of a business and (2) any changes in value—profit or loss—taking position in the entity during a particular period.

Management officials, investors, and credit grantors all require such information: management in order to assess the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to analyze the financial statements of an entity in finding whether to grant a loan.

Bits and pieces of financial and numerical record charts are uncovered for almost every group of people with a commercial history. Records of trade contracts were uncovered in the ruins of Babylon, and accounts for both farms and estates were created in ancient Greece and Rome. The dual-entry way of bookkeeping started with the progression of the business republics of Italy, and tutorials for bookkeeping were created within the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made correct financial books a paramount factor. The past of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, in some part, assisted forming it. The worldwide market of industrial and commercial activity demanded more professional decision-making processes, which then required higher sophistication in the selection, classification, and presentation of information, more so with the assistance of computers. Taxation and government legislation became more detailed and resulted in greater demand for information; business firms had to have information available to bolster 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 requirement for bookkeeping for their own departmental operations increased.

Though bookkeeping processes can be very complex, it is all based on two kinds of books used in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger has the details of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are prepared from the trial balance posted within the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of the changes that happen in the business equity resulting from the transactions of the period. The balance sheet provides the financial condition of the enterprise at the 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.
