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

The most common question that is asked when buying a new projector for the home, office, or classroom is: should I purchase an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different models available, it can be overwhelming for customers to pick between both technologies. The fact is that LCD projectors have far superior image quality and colour accuracy. The article below will explain why DLP projectors struggle with bringing up a comparable standard of image quality.

Imagine a set of blinds in your household on your bedroom window. By pulling a rod you can make the shutters open or closed, according to whether you want to let light in or not. This is exactly how an LCD projector functions. Each pixel functions like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is constructed 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 is switched on to when the content reaches your screen is ultimately important with regard to image quality, brightness and colour accuracy. LCD projectors shine 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 cast the elements of the image by shining each pixel on and off. The pixels are then combined in a glass prism to send the projector image. An important point to remember about LCD projectors is that all three colours are projected onto your projector screen all at the same time. The way a DLP projector operates is totally different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is processed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image requires a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s vision will then pull together each coloured element of the image into the total image. From LCD projectors, all colours are available all the time to offer the highest brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some DLP developers have added a white segment into the colour wheel to improve overall brightness, but this also lessens colour accuracy.

I see in forums all the time that DLP provides a higher contrast ratio and thus must be superior. For those who are uncertain, 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 producing. DLP projectors do have high contrast specifications as compared to many LCD projectors. Initially, this seems to be a benefit, however, in real life, the true black level is determined by the ambient light in the room in which the projector is used. Do not be duped by contrast specifications on websites and in brochures.

When the content you wish to view requires moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most often seen 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 position between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because all the colours are processed at the same time. DLP manufacturers have created 3DLP solutions using 3 chips to solve the colour break up error, but the cost of these projectors make them almost impossible for the large part of businesses and consumers.

Another differentiation 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 various colours of light refract different amounts when projected through the same lens. The disadvantage 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 obviously different and refract light in different ways. Generally with a DLP projector, a spill of yellow colour will be projected above and a superfluous blue will appear below an image containing something as simple as a lone black line. In building LCD projectors can be fixed to take away these effects on the projected image, because each colour is directed on its own LCD panels.

The sole veritable plus (excluding price) with picking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transport and cannot be traded off against the image benefits of LCD projectors. If the result of the picture quality is crucial to you, then the choice is simple. Go for an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht had been a pleasure craft used initially by royalty and later by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private challenges. English yachting began 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, reigned 1685–88), built other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting rose as popular for the affluent and nobility, but after that period the habit did not last.

The first yacht association in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and held large naval panoply and rigour. The closest thing to racing boats was the “chase,” for which the “fleet” pursued a fictional enemy. The club endured, mostly as a social club, until 1765, and in 1828, after joining with other societies, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated manner on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was then known as 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 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 location of British yachting. The society at Cowes became the Royal Yachting Club, again at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing tests for great stakes were held, and the club life was superlative. It came to be that the Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English gained power. Sailing was for the most part for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a minimum of luxury and elegance for the later yachts in the area from the late 19th century. The first enduring American yacht society, the Detroit Boat Club, was formed 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 took the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the latter half of the 19th century. The design of large yachts was first greatly affected by the success of America, which was drawn by George Steers for a association started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its victory at Cowes in 1851. The first yachts were not designed and manufactured in the modern sense, with just a model being used. Not until the later half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the use of the research of aerodynamics do for the design of sails and rigging what such study had previously done for hulls.

Because nearly all sailboats had been individually built, there came a need for handicapping boats as this was previous to the one-design class boats were designed. Therefore, a rating rule was created, which ended up in the International Rule, adopted in 1906 and amended in 1919. Today, one of the most rapidly flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for those boats can be held on an even playing field with no handicapping necessary. A great example is the generic International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

For the time that yachting was an activity mostly for the nobility and the affluent, cost was no object, and the size of boats increased, in both length and weight. The rise and popularity of smaller boats happened 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of less sizeable craft. Following this in the 20th century, notably after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a preferred 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
After the decade 1840–50, when steam began to replace sail power in public boats, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure boats. Large power yachts were furthered to a high element, and long-distance sailing turned into a favourite activity of the rich. The earliest power yachts were paddle-wheel boats; these then made way to yachts powered by the completely submerged screw or propeller sort of propulsion. As in the case of naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for many years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were exclusively power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a push in the manufacture of large steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of at least 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service in World War II.

As more sizeable and more dependable internal-combustion engines were created, many bigger yachts began using them for power. The creation of the diesel engine, employing heavy oil for fuel, progressed for World War I. In the decade after that, bigger power-yacht creation flourished, reaching a climax in the Orion (1930) at 3,097 tons. In that point the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of large power yachts fell away after 1932, and the fashion thereafter was for smaller, less expensive craft. After World War II, many small naval craft were bought by private owners for conversion to yachts. By the late 20th century, yachting had become a globally beloved activity enjoyed by thousands of yachtsmen individually owning and maintaining their own small leisure boats. The number of boats and yachtsmen is increasing steadily, not only in the traditional areas along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the impact they have on the placement of income and wealth. A proportional tax is the kind of tax that impinges the same relative burden on every taxpayer—i.e., in the case where tax liability and income grow in relative proportion. A progressive tax is characterized by a more than proportional rise in the tax onus relative to the growth in income, and a regressive tax is recognised by a less than proportional rise in the related liability. Therefore, progressive taxes are viewed as removing inequity in income distribution, while regressive taxes may result in increasing these inequalities.

The taxes that are usually thought to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, could become less so in the upper-income categories—particularly if a taxpayer is permitted to lower his tax base by nominating deductions or by excluding certain income components from his taxable income. Proportional tax rates if applied to lower-income demographics could also be more progressive if exemptions of a personal nature are made.

Income measured over the course of a given year may not definitely come up with the most appropriate measure of taxpaying requirement. For example, transitory growth in income can be saved, and in temporary declines in income a taxpayer may decide to provide for consumption by reducing savings. So, if taxation is made comparable alongside “permanent income,” it should be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (excepting those on luxuries) tend to be regressive, because the spread of individual income consumed or spent on a specific good lessens as the rate of personal income increases. Poll taxes (also known as head taxes), calculated as a fixed amount per capita, obviously are regressive.

It is hard to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty surrounding 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 decided.

In analysing the economic purpose of taxation, it is essential to distinguish between several concepts of tax rates. The statutory rates will include those nominated in the law; often these are marginal rates, but occasionally they are mean rates. Marginal income tax rates indicate the fraction of incremental income taken by taxation when income grows by one dollar. Thus, if tax onus increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that grow as income increases. Heavy analysis of marginal tax rates should take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than indicated by the statutory rates. Since marginal rates indicate how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for assessing 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 depend on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the fraction of total income that is taken in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates commonly grow with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received predominantly by high-income households could dampen these effects, forcing regressivity, as displayed by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs utilised for projection systems are generally small reflective or transmissive panels set off by a forceful arc lamp source. A series of lenses enlarges the reflected or transmitted image and then casts it on a screen. For front-projection systems the LCD is placed on the side of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of higher expense and performance might have three separate LCD panels, forming separate red, green, and blue images that come together to reflect a coloured image on the screen.

The growing need for visual displays has put a special emphasis on the switching speed of liquid crystals. This has required the invention of devices employing smectic liquid crystals, particular kinds of which possess a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. In 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 displayed in the figure. The host liquid crystal possesses optically active molecules, and a subtle outcome of the optical activity and the slant of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through 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 coupled to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark if one or more polarizers are used.

SSFLC devices have been marketed for larger passive-matrix presentations, but their high cost and detail has hindered them from creating any significant effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be used in time-sequential colour systems, in which costly colour filters are emulated by a coloured backlight that flashes red, green, and blue in quick speed (approximately 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state in the red and green periods then to a nontransmissive state during the blue period, creating the upshot 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 forms, the chair could be of most importance. While many other forms (except the bed) are designed to support objects, the chair supports our human form. The term chair was regarded here in the general sense, from stool to throne to developed makes such as a bench or sofa, which can be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously labeled.

The social history of the chair is as exciting as its history as a creative craft. The chair is not simply a physical support and/or an aesthetic item; it historically is a symbol of social place. From the past royal courts there were plain distinctions between being led to a chair with arms, or a chair with a back but without arms, or having to sit on a stool. Since the past century, the director’s and manager’s chair has been an identifier of superior position, as well as in democratic government meeting the speaker sits on a high-set floor.

As its furniture construction, the chair can be employed for a range of different makes. There are chairs designed to attend to man’s age and physical abilities (the high chair, the wheelchair) and to show his rank in society (the executive chair, the throne). During past times there were chairs to be born in (birth chairs); since the 20th century, there have been chairs for ending life (the electric chair). There are chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded up, chairs on wheels, and chairs on runners.

Modern day living has designated unique chairs for automobiles and aircraft. All these chair kinds has been evolved to suit to changing human requirements. For its significant connection with man, the chair lives to its full importance only when being used. Although it is not relevant to one’s appreciation of a cupboard or a chest of drawers if there might be things inside or not, a chair is best seen and clearly evaluated by a person using it, because chair and sitter need one another. Thus the individual elements of the chair are named as the names of our human parts: arms, legs, feet, back, and seat.

Because the fundamental role of a chair is to support a body, its value is judged basically on how well it does measure up to this practical purpose. Within the creation of the chair, the designer is restricted in the static laws and principal measurements. In these limits, however, the chair builder has extensive freedom.

The history of the chair was a period of several thousand years. There existed cultures that had iconic chair types, as expressions of the premier object in the industries of handling and design. Out of 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 items of skilled scheme, are today seen from discoveries made in tombs. The first one of them is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs crafted like those of a particular animal, a curved seat, and leading to a sloping back supported over vertical stretchers. In this design a durable triangular form was obtained. There was to our knowledge no significant differentiation between the design of Egyptian thrones and chairs for ordinary populace. The real difference lies in the intricacy of ornamentation, in the evidence of more valuable inlays. The Egyptian folding stool likely was created to be an easily packed seat for army soldiers. As a camp stool the kind stayed around until much later points. But the stool also then played the task of a ceremonial seat, its mechanical history as a folding stool fast forgotten. This can already be noted, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are constructed in the form of folding stools but cannot be folded because the seats are made out of wood. The plain structure of the folding stool, being of two frames that cycle on metal bolts and bear a seat of leather or fabric held between them, reappeared but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of these is the folding stool, of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is recognised not from any ancient item still around but as seen in a wealth of pictorial items. The better recognised is the klismos drawn on the Hegeso Stele at the Dipylon burial area just out of Athens (c. 410 BC). The klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of these legs could be shown. These curved legs were considered to have been executed of bent wood and were as such subjected to huge pressure from the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore super solid and were overtly indicated.

The Romans borrowed from the Greek design; some statues of seated Romans are chairs of a more heavyset and which appear to be a rather crudely constructed klismos. Both types, light and heavy, were revived as part of the Classicist epoch. The klismos style is seen in French Empire styles, in English Regency, and in some brands of marked iconicism around Denmark and Sweden during 1800.

China
The history of the chair in China isn’t able to be traced as well as that of Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed series of images and works of art had been kept, displaying the insides and outer parts of Chinese households and the designs of furniture. Also kept from the 16th century are some chairs crafted from wood or lacquered wood, that bear an astonishing similarity to designs of ancient chairs.

Just like in Egypt, there was two major chair designs in China: a chair of four legs and a folding stool. That four-legged chair has been designed both with or without arms but always having the square seat and straight stiles (vertical side supports) to firm the back. In one image, though, the stiles had been delicately curved above the arms so as to fit the shape of the S-shaped back splat (the centre upright of its chairback). All three areas had been mortised on the yoke-like top rail. While the design of the back splat later had an influence on English chairs in the Queen Anne period, wooden sections that only to a particular limit embolden corner joints (and were loose to top that off) represent a design particular to Chinese chairs. The four legs pass through the seat frame, which stops upon the rounded staves. Members are round in section or has rounded edges—references maybe to the bamboo tradition. The seat is not pleasant and occasionally had a plaited seat. These chairs needed the sitter to remain stiff and upright; if too much weight is pushed on the back, the chair has a habit of toppling over. In patriarchal Chinese houses of this era armchairs probably were only for the senior people, for they were given great esteem.

The Chinese folding stool is believed to have come to China from the West. It does not vary very much from the Egyptian and Scandinavian folding stools, but it has a dissimilarity in that the top rail is elegantly fixed to the two legs of the stool by a curved member, which is usually seen with metal mounts. From a Western point of view the ultimate effect of these furniture designs is stylized. The structure and aesthetic parts are combined in a style that is both naïve and refined. The patched up appearance is an upshot of the way that the individual items do not seem to have been fixed by use of either glue or screws, but have been mortised onto one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its mark on the chair. Paintings project a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of tiny pads. The front board and a related board from the back could be folded after unscrewing some small iron hooks. Therefore the chair was an easily portable piece of furniture while traveling which, in the same time, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is found in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this style of chair is also found in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not decided that the design actually originated in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slim shape; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in vast amounts, as can be surmised from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up along a wall. The form 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 form—that was, to say, as progressed in Paris around 1750—conquered most of Europe and was imitated or copied during the mid-20th century. The model owes this popularity to a combination of leisure and delicacy. The seat adheres to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of fairly thick measurements; but all members are deeply molded, all extra wood has been taken away, and more expensive items might be further embellished with highly delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for any upholstery on the seat, back, and armrests; cane is occasionally used as an alternative to upholstery.

English chairs from the 18th century were more differentiated in design than the French. The French preference for stylistic uniformity, which disseminated from the highest circles in Paris and Versailles through most of France and became the preference 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 reknowned 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 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, 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 transactions of a business. Bookkeeping provides the numbers from which accounts are made but is a previous process, required prior to accounting.

Fundamentally, bookkeeping finds two types of information: (1) the current value, or equity, of an enterprise and (2) the change in value—profit or loss—taking place in the entity within a given time period.

Management officials, investors, and credit grantors all need to have this information: management in order to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to assess the upshot of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an entity in finding whether to give a loan.

Bits and pieces of financial and numerical charts are uncovered for almost every civilization with a commercial history. Records of commercial contracts were found in the remains of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The double-entry process of bookkeeping came up with the furthering of the enterprising republics of Italy, and instruction manuals for bookkeeping were produced in the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial books a must-have. The history of bookkeeping, in fact, reflects closely the past of commerce, industry, and government and, in some part, assisted in forming it. The worldwide spread of industrial and commercial activity called for higher professional decision-making processes, which in turn demanded greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislation became more significant and resulted in higher demand for information; enterprising firms had to have available information to go with 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 need for bookkeeping for their own inner departmental operations increased.

While bookkeeping processes can be very multifaceted, it is all based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so forth), and the ledger must have the record of individual accounts. The daily records in the journals are written in the ledgers.

Every month, generally, an income statement and a balance sheet are made from the trial balance posted in the ledger. The purpose of the income statement or profit-and-loss statement is to provide an analysis of those changes that took place in the enterprise equity resulting due to the events of the period. The balance sheet shows the financial position of the enterprise at the particular point in time with regard to 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 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.
