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

The common question customers ask when acquiring 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, which stands for ‘digital light processing’ are the two top projector imaging technologies. With so many business brands and models available, it can be challenging for the buyer to pick between these technologies. The simple fact of the matter is that LCD projectors offer superior image quality and colour accuracy. The following article tells you why DLP projectors struggle with bringing up an equal grade of image quality.

It’s like a set of blinds in your household covering your bedroom window. By pulling on a rod you can make the shutters open or closed, according to if you want to let light in or not. And this is exactly how an LCD projector works. Each pixel functions like its own shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the professionals like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the picture reaches your screen is absolutely significant to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by shining 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 delivered onto your wall all at once. The way a DLP projector operates is widely different and even the produced image shows up is not the same. With DLP, white light from the lamp is projected through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to making an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then combine each coloured element of the image into a complete image. From 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, causing lower colour brightness and accuracy. Some DLP developers have included a white segment for the colour wheel to improve brightness overall, but this then detracts from colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and ergo 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 system is able to produce. DLP projectors do offer high contrast specifications when compared to a majority of LCD projectors. At one glance, this appears to be a plus, however, in reality, the true black level is determined by the ambient light in the room while the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to project includes moving images, DLP projection technology also has image marks, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is unavoidable 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 at the same time. DLP designers have come up with 3DLP solutions using 3 chips to resolve the colour break up problem, but the price of these projectors make them impractical for most businesses and consumers.

Another variance between LCD and DLP is how they balance for the refractive qualities of light. Jump back to high school science, and remember how different colours of light refract various amounts when directed through the same lens. The downside with DLP projectors is that they have the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in different ways. Most of the time with a DLP projector, some extra yellow colour will come through above and a spill of blue will come through below an image as simple as a single black line. While being built LCD projectors can be adjusted to take away these effects on the projected image, because each colour is processed on separate LCD panels.

The only actual benefit (excluding price) with taking a DLP projector is its smaller size and weight. However, this is only relevant with regard to mobility and must be traded off against the image advantages of LCD projectors. If overall picture quality is crucial to you, then the choice is easy. Choose an LCD projector! LCD projectors will always create bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the early yacht had been a pleasure craft used initially by royalty and then by the burghers for the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting became popular for the affluent and nobility, but after that time the fashion did not last.

The first yacht association in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held great naval panoply and rigour. The closest thing to racing was the “chase,” for which the “fleet” pursued an imagined enemy. The club went on, mostly as a social club, until 1765, and in 1828, by merging with other groups, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered manner on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht club had been initiated at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing location of British yachting. The organisation at Cowes became the Royal Yachting Club, likewise at the accession of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the club life was lovely. It came to be that the Royal Yachting Club boats were raised in size to over 350 tons.

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

Kinds of sailboats
The first sailing yachts 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 style of sizeable yachts was first largely impacted by the victory 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.) was named after its victory at Cowes in 1851. Earlier yachts were not designed and crafted in today’s sense, with merely a model used. Not until the latter half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the employment of the study of aerodynamics do for the design of sails and rigging what it had already done for hulls.

Because nearly all sailboats had to be individually manufactured, there was a requirement for handicapping boats as this was before the one-design class boats were designed. Therefore, a rating rule was decreed, which is found in the International Rule, accepted in 1906 and revised in 1919. Today, one of the most rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are built to standard specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between these boats can be had on an even basis with no handicapping required. A great example is the uniform International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

For the time that yachting was an activity largely for the nobility and the rich, cost was no object, and the size of boats grew, in both length and weight. The rise and preference of smaller boats occurred in the second half of the 19th century out of 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 demonstrated the hardiness of small yachts. Following this in the 20th century, particularly after World War II, smaller racing and leisure yachts became commonplace, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, at which point steam began to replace sail power in market boats, the steam engine, and later the internal-combustion engine, were increasingly used in leisure boats. Bigger power yachts were furthered to a high standard, and long-distance cruising was a preferred occupation of the wealthy. The earliest power yachts were paddle-wheel boats; those then gave rise to boats powered by the wholly submerged screw or propeller type of propulsion. Like naval and merchant yachts, auxiliaries with both sail and power were the yacht fashion for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were exclusively power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of more sizeable 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, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service for World War II.

As larger and more dependable internal-combustion engines were created, many large yachts started using them for power. The creation of the diesel engine, with heavy oil for fuel, progressed during World War I. During the decade that followed, large power-yacht building blossomed, reaching a climax in the Orion (1930) at 3,097 tons. In that period the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power yachts declined from 1932, and the fashion from then was toward smaller, less pricey yachts. From World War II, lots of small naval vessels were traded by private owners for conversion to yachts. By the late 20th century, yachting had become a globally popular sport enjoyed by thousands of yachtsmen personally manning and upkeeping their own small pleasure boats. The amount of craft and sailors has increased steadily, not only in the traditional locations on the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the impact they have on the placement of income and wealth. A proportional tax is the kind of tax that imposes the same relative burden on all taxpayers—i.e., when tax liability and income increase in relative proportion. A progressive tax is recognisable by a higher than proportional growth in the tax onus in relation to the growth in income, and a regressive tax is recognised by a less than proportional increase in the comparable burden. Ergo, progressive taxes are viewed as taking away a lack of equality in income distribution, but regressive taxes are seen to result in increasing these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, could become less so within the upper-income categories—especially if a taxpayer is allowed to lessen his tax base by nominating deductions or by excluding particular income parts from his taxable income. Proportional tax rates which are applied to lower-income demographics will also be more progressive if such personal exemptions are claimed.

Income measured over a given year may not absolutely offer the most appropriate measure of taxpaying requirements. For example, transitory growth in income may be saved, and during temporary declines in income a taxpayer might choose to finance consumption by reducing savings. Ergo, if taxation is regarded along with “permanent income,” it would be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (with the exception of luxuries) tend to be regressive, because the spread of one’s income consumed or spent for specific goods decreases as the level of personal income is raised. Poll taxes (also called head taxes), levied as a standard amount per capita, patently are regressive.

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

In regarding the economic purposes of taxation, it is important to differentiate between varied concepts of tax rates. The statutory rates are those dictated in the law; commonly these are marginal rates, but for some cases they are mean rates. Marginal income tax rates signify the fraction of incremental income demanded by taxation when income grows by one dollar. Hence, if tax onus rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that increase as income increases. Structured analysis of marginal tax rates must consider provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for appraising incentive effects of taxation. It is even more complicated to nominate the marginal effective tax rate applied to income from business and capital, because it may be reliant on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds 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 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 grows with income. Average income tax rates usually grow with income, both because personal allowances are permitted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households might dampen these effects, producing regressivity, as displayed by average tax rates that lessen as income grows.

The Development of Data Projectors

The LCDs used in projection systems are usually small reflective or transmissive panels set off by a bright arc lamp source. A number of lenses enlarges the reflected or transmitted image and casts it onto a screen. For front-projection systems the LCD is located on the same area of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of more expense and performance might use three separate LCD panels, reflecting separate red, green, and blue images that mesh to create a coloured image on the screen.

The increase in demand for video presentations has placed a growth in emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items employing smectic liquid crystals, certain ones of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most developed smectic device. Inside it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and within the layers the molecules are slanted, as displayed in the figure. The host liquid crystal possesses optically active molecules, and a slight result 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 within the plane of the layers. So, there must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly partnered 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 by doing so reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark when one or more polarizers are used.

SSFLC devices have been commercialized for large passive-matrix presentations, but their cost and detail has prevented them from having any remarkable movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as parts in projection systems or as viewfinders in digital cameras. Their speedy reacting allows them to be employed in time-sequential colour systems, in which high cost colour filters are taken out for a coloured backlight that flashes red, green, and blue in rapid speed (approximately 100 cycles in a second). For example, the liquid crystal might be switched to a transmissive state for the red and green periods and to a nontransmissive state during the blue period, with the upshot that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture needs, the chair could be of most importance. While most of the other items (except the bed) are designed to support objects, the chair supports your human form. The term chair is looked upon here in the most open sense, from stool to throne to developed makes for example a bench and sofa, which may 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 art and craft. The chair is not merely a physical support and an aesthetic piece; it is historically semiotic of social place. In the old royal courts there were important signifiers between having a chair with arms, sitting on a chair with a back but no arms, or having to make do with a stool. Since the recent century, a director’s or manager’s chair has risen iconic of superior status, and even in democratic government debate the speaker sits on a raised platform.

As a furniture purpose, the chair is employed for a range of various purposes. There are chairs created to suit man’s age and physical abilities (the high chair, the wheelchair) and for his rank in society (the executive chair, the throne). From the past there were chairs used for birthing (birth chairs); from the 20th century, there have been chairs used to die in (the electric chair). We design chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded, chairs on wheels, and chairs on runners.

Modern living has demanded special chairs for use in automobiles and aircraft. Every one of these chair kinds have changed to conform to growing human needs. Due to its unique link with man, the chair exists to its full meaning only when in employ. Whereas it does not make any difference to one’s appreciation of a cupboard or a set of drawers whether there might be anything inside or not, a chair is best seen and fairly tested by a person utilising it, because chair and sitter need each other. Thus the different parts of the chair have been labeled according to the elements of our human form: arms, legs, feet, back, and seat.

Because the original work of the chair is to support our human body, its worth is evaluated primarily from how completely it fulfills this practical job. Within the construction of the chair, the builder is bound under certain static regulations and principal measurements. Within these boundaries, however, the chair designer has great freedom.

The history of the chair lasts over an era of several thousand years. There are cultures that made significant chair shapes, as expressions of the premier object in the areas of technique and aesthetics. Out of those peoples, a note needs to 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of masterful design, are today found from tombs. One of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs shaped not unlike those of a designated animal, a curved seat, and leading to a sloping back supported above vertical stretchers. From this a durable triangular design was made. There was from our view no particular change between the construction of Egyptian thrones and chairs for typical peasantry. The only difference lies in the level of ornamentation, in the evidence of more valuable inlays. The Egyptian folding stool most likely was developed to be an easily portable seat for officers. As a camp stool this form stayed during much later periods. But the stool also then was made for the task of a ceremonial seat, its technical history as a folding stool being forgotten. This can already be seen, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were made in the shape of folding stools but can not be folded as the seats are created out of wood. The simple make of the folding stool, composed of two frames that turn on metal bolts and have a seat of leather or fabric fastened between them, then appeared but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this form is the folding stool, crafted out of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not with any ancient fossil still in form but in a large amount of pictorial evidence. The iconic kind is the klismos seen on the Hegeso Stele at the Dipylon burial area near Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs would be visible. These creative legs were presumed to be executed of bent wood and were in that case put under a large amount of pressure with the weight of the sitter. The joints fastening the legs to the frame of the seat had to be therefore very stable and were particularly signified.

The Romans adopted the Greek design; a number of casts of seated Romans display chairs of a denser and are a kind of less intricately crafted klismos. Both designs, light and heavy, were popularised as part of the Classicist time. The klismos influence can be seen in French Empire furniture, in English Regency, and in some special kinds of notable individuality within Denmark and Sweden around 1800.

China
The progression of the chair in China is not able to be charted as long as the ancestry of chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed series of drawings and works of art was kept, displaying the interior and outside of Chinese households and the designs of furniture. Another preservation from the 16th century are some chairs constructed of wood or lacquered wood, that show an amazing similarity to styles of previous chairs.

Just as in Egypt, there were two particular chair designs in China: a chair that had four legs and a folding stool. That chair has been constructed both with or without arms however always with a square seat and straight stiles (standing side supports) to support the back. In one design, though, the stiles are marginally curved on top of the arms to sit correctly with the angle of the S-shaped back splat (the centre upright of its chairback). The three parts are mortised onto the yoke-like top rail. Though the idea of the Chinese back splat later had an inspiration for English chairs within the Queen Anne period, wooden members that only to a limited limit support corner joints (and are loose additionally) indicate a feature particular to Chinese chairs. The four legs sit through the seat frame, which stops upon the rounded staves. Members are round in section or is given rounded edges—acknowledging as may be to the bamboo tradition. The seat is not comfortable and may have had a plaited form. These chairs required the sitter to be stiff and upright; if too much pressure is forced on the back, the chair has a habit of falling over. In patriarchal Chinese homes of this era armchairs presumably were allowed only for older members of the family, for they were esteemed greatly.

The Chinese folding stool is thought to have taken to China from the West. It does not vary so very much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is prettily joined to the two legs of the stool by using a curved member, which is more often than not provided with metal mounts. From a Western point of view the ultimate effect of both of these furniture designs is stylized. The constructive and aesthetic issues are combined in a manner that is both naïve and refined. The pieced-together appearance is a result of the way that the individual members do not seem to have been joined together by means of either glue or screws, but have been mortised into one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its mark on the chair. Artworks show a design of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between the layers, stitched to show up a pattern of little pads. The front board and a related board in the back could be folded after loosening some little iron hooks. Thus the chair was an easily 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 kind of chair can be found in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair might also be made in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not determined that the form actually started in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in considerable quantities, as surmisable from one of Abraham Bosse’s engravings, in which there is an entire row of such chairs lined up along a wall. The design asserts itself with its shapely 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, as progressed in Paris around 1750—spread through most of Europe and was imitated or copied into the mid-20th century. The style owes such popularity to a combination of comfort and delicacy. 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 achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of rather thick measurements; but all the members are deeply molded, all extra wood has been cut away, and finer items can be further embellished with special delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; canework is sometimes used instead of upholstery.

English chairs in the 18th century were more variable in design than the French. The French manner for stylistic uniformity, which spread from the premier 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 popularised and was widely distributed throughout the world.

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

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the charting of the money values of the function of a business. Bookkeeping provides the information from which accounts are made but is a different process, prior to accounting.

Fundamentally, bookkeeping provides two parts of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking place in the entity within a single period of time.

Management officials, investors, and credit grantors all demand such information: management so as 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 regarding buying, holding, and selling securities; and credit grantors to judge the financial statements of an enterprise in deciding whether to give a loan.

Traces of financial and numerical recordkeeping are uncovered for almost every country with a commercial history. Records of business contracts have been uncovered in the ruins of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The two-entry method of bookkeeping came up with the progression of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were produced in the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial bookkeeping a requirement. The past of bookkeeping, in fact, reflects the past of commerce, industry, and government and, in some part, assisted in forming it. The global movement of industrial and commercial activity demanded better sophisticated decision-making processes, which then needed higher sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government regulation became more significant and resulted in increased requirement for information; businesses 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 grew, and the demand for bookkeeping for their inner departmental operations became larger.

Although bookkeeping methods can be extremely multifaceted, all of it is based on two kinds of books used in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so on), and the ledger must have the record of individual accounts. The daily records from the journals are entered in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are created from the trial balance posted in the ledger. The purpose of the income statement or profit-and-loss statement is to display an analysis of those changes that happen in the ownership equity resulting due to the transactions of the period. The balance sheet gives the financial condition of the business at any particular point taken 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 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.
