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

How the light source is processed from the point when the projector turns on to when the content reaches your screen is ultimately important with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels cast the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. Something to know about LCD projectors is that all three colours are directed onto your screen at the same time. The way a DLP projector operates is totally different and even the way an image looks 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 projecting an image forms 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 sent in sequence on the screen, one colour at a time. The viewer’s eyes will then pull together each coloured element of the image into a whole image. From LCD projectors, all colours are available all the time to offer the highest brightness and great colour accuracy. In DLP, only one colour is available at once, causing lower colour brightness and accuracy. Some DLP developers have included a white segment for the colour wheel to improve general brightness, but this goes and lessens colour accuracy.

I hear in forums all the time that DLP has a higher contrast ratio and thus must be superior quality. For those 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 capable of producing. DLP projectors do possess high contrast specifications as compared to many LCD projectors. Initially, this can seem to be a plus, however, in real life, the true black level is determined by the ambient light in the room while the projector is being used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to bring to life needs moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because the colours are delivered at once. DLP builders have created 3DLP solutions using 3 chips to resolve the colour break up issue, but the expense of these projectors make them impractical for many businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Remember back to high school science, and recall when they taught you how various colours of light refract varied amounts when projected through the same lens. The downside with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. 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 of something as simple as a straight black line. In manufacturing LCD projectors can be adapted to minimize these effects on the projected image, because each colour is projected on its own LCD panels.

The only real advantage (excluding price) with taking a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to mobility and has to be traded off against the image superiority of LCD projectors. If the result of the picture quality is crucial to you, then the choice is easy. Take an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image errors.

The first yacht club in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with much naval panoply and formality. The closest thing to a race was the “chase,” when the “fleet” pursued an imaginary enemy. The club endured, mostly as a social club, until 1765, and in 1828, by joining with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated fashion on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to monarchy in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed 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 continued setting of British yachting. The society at Cowes became the Royal Yachting Club, likewise at the accession of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for large bids were held, and the social life was splendid. Ultimately Royal Yachting Club boats were raised in size to more than 350 tons.

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

Kinds of sailboats
The first sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The craft of sizeable yachts was first greatly put upon by the win of America, which was created by George Steers for a syndicate started 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. The first yachts were not designed and crafted in the modern sense, with just a model for an outline. Not until the later half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the use of the science of aerodynamics do for the craft of sails and rigging what it had done earlier for hulls.

Because most of all sailboats had been individually manufactured, there was a need for handicapping boats before the one-design class boats were made. Hence, a rating rule was written, which ended up in the International Rule, adopted in 1906 and edited in 1919. Today, one of the rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are created to standard specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be held on an even playing field with no handicapping at all. A prime 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 belonged largely for the royal and the rich, money was no problem, and the size of boats developed, in both length and weight. The rise and preference 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) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of smaller yachts. Following this in the 20th century, for the larger part after World War II, smaller racing and recreational yachts became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, at which point steam started to emulate sail power in commercial boats, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Sizeable power yachts were developed to a high degree, and long-distance sailing turned into a fond activity of the wealthy. The first power yachts were paddle-wheel boats; those then gave way to boats powered by the completely submerged screw or propeller sort of propulsion. Like naval and merchant boats, auxiliaries with both sail and power were the yacht archetype for many years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the majority were only power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the construction of more sizeable steam yachts. Conspicuous among 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 more than 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service during World War II.

As more sizeable and more reliable internal-combustion engines were developed, many large boats started using them for power. The creation of the diesel engine, with heavy oil for fuel, advanced from World War I. From the decade following that, large power-yacht manufacture blossomed, reaching a climax in the Orion (1930) at 3,097 tons. From that period the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power craft fell away after 1932, and the trend after that was for smaller, less costly craft. After World War II, a lot of small naval boats were sold to private owners for conversion to yachts. In the late 20th century, yachting is a globally beloved competition enjoyed by thousands of yachtsmen who are actually manning and upkeeping their own small pleasure boats. The number of craft and sailors increased steadily, not only in the traditional areas on the beach but also on inland waterways and lakes.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, might become less so within the upper-income categories—in particular if a taxpayer is able to lessen his tax base by claiming deductions or by leaving out certain income elements from his taxable income. Proportional tax rates when applied to lower-income demographics would also be more progressive if such personal exemptions are declared.

Income measured over a given year may not absolutely give the most suitable measure of taxpaying ability. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer could decide to provide for consumption by decreasing savings. Thus, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (excepting luxuries) are usually regressive, because the spread of one’s income consumed or spent on specific goods lessens as the level of personal income grows. Poll taxes (also called head taxes), calculated as a standard amount per capita, obviously are regressive.

It is difficult to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to a lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden rests for the most part on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effects of taxation, it is necessary to differentiate between various concepts of tax rates. The statutory rates are nominated in legislature; commonly these are marginal rates, but sometimes they are average rates. Marginal income tax rates note the fraction of incremental income demanded by taxation when income rises by one dollar. So, if tax burden rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates should take into account provisions apart from 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 more than indicated within the statutory rates. Since marginal rates signify how after-tax income moves 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 understand the marginal effective tax rate applied to income from business and capital, as it may depend 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 nothing under a consumption-based tax.

Average income tax rates display the percentage of total income that is required in taxation. The pattern of average rates is the one that is in consideration for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually grow with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households can swamp these effects, allowing regressivity, as indicated by average tax rates that decrease as income grows.

The growth in demand for film displays has put a growth in emphasis on the switching speed of liquid crystals. This has led to the invention of devices employing smectic liquid crystals, particular types of which emit a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most complex smectic device. Within it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a minor turn up of the optical activity and the angle 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 in the plane of the layers. So, there is 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 correct 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 in the case that one or more polarizers are employed.

SSFLC devices have been publicized for large passive-matrix presentations, but their cost and intricacy has stopped them from making any remarkable impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their fast reaction allows them to be employed in time-sequential colour systems, in which costly colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick speed (around 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods and to a nontransmissive state in the blue period, creating the upshot that the eye sees an average of red and green light, or the colour yellow.

The social history of the chair is as stimulating as its history as a creative art. The chair is not just a physical support and an aesthetic object; it is also a symbol of social placement. Within the historical royal courts there were significant connotations between being seated on a chair with arms, sitting on a chair with a back but no arms, or having to utilise a stool. During the last century, the director’s and manager’s chair has been an identifier of superior status, and in democratic government debate the speaker sits on a raised level.

In its furniture form, the chair can be used for a variety of different makes. There are chairs created to attend to man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his rank in society (the executive chair, the throne). From historical days there were chairs for birthing (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs in automobiles and aircraft. All these chair kinds has changed to fit to growing human needs. For its close link with man, the chair lives to its full meaning only when being utilised. While it is not relevant to one’s appreciation of a cupboard or a chest of drawers if there might be anything inside or not, a chair is understood best and fairly evaluated by a person sitting on it, because chair and sitter complement the other. Thus the various areas of the chair have been named like the areas of the human shape: arms, legs, feet, back, and seat.

Because the simple purpose of your chair is to support a body, its credit is tested generally for how well it does fulfill this practical role. In the build of a chair, the builder is limited with certain static regulations and principal measurements. Inside these restrictions, however, the chair designer has marvellous freedom.

The history of the chair extends over an era of several thousand years. There is evidence of civilizations that created iconic chair shapes, as expressions of the topmost craft in the industries of craft and design. From such peoples, a mention can 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 result of masterful scheme, are now seen from tomb findings. First of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair has four legs crafted like those of a chosen animal, a curved seat, with a sloping back supported with vertical stretchers. In this design a strong triangular structure was made. There was from our view no significant change between the creation of Egyptian thrones and chairs for common people. The general difference was in the brand of ornamentation, in the choice of expensive inlays. The Egyptian folding stool in all likelihood was designed for an easily carried seat for army officers. As a camp stool the stool stayed around til much later days. But the stool also then was designed for the use of a ceremonial seat, its original job as a folding stool ignored or forgotten. This can now be observed, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were made in the shape of folding stools but aren’t able to be folded because the seats are made with wood. The simplistic build of the folding stool, being of two frames that rotate on metal bolts and hold a seat of leather or fabric held between them, also appeared some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this kind is the folding stool, made of ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not in any ancient object still in form but as in a large amount of pictorial material. The most well known is the klismos placed on the Hegeso Stele at the Dipylon burial location outside Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those were shown. These strange legs were most likely to have been crafted with bent wood and were thus had a large amount of pressure under the weight of the sitter. The joints holding the legs to the frame of the seat would have been therefore very durable and were particularly drawn.

The Romans adopted the Greek design; some statues of seated Romans offer evidence of a denser and apparently rather crudely built klismos. Both styles, the light or heavy, were popularised within the Classicist period. The klismos style is found in French Empire chairs, in English Regency, and in particular brands of notable individuality in Denmark and Sweden around 1800.

China
The history of the chair in China is not able to be traced as far back as the history of chairs in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged series of images and works of art had been protected, showing the insides and outside of Chinese homes and the kinds of furniture. Also preserved from the 16th century are some chairs made of wood or lacquered wood, that bear an amazing familiarity to images of past chairs.

Like in Egypt, there were two particular chair designs in China: a chair with four legs and a folding stool. That four-legged chair was constructed both with or without arms however never missing its square seat and straight stiles (vertical side supports) to give support to the back. In one type, it has been found, the stiles were slightly curved over the arms for the purpose of conform to the form of the S-shaped back splat (the basic upright of the back). The three sections are mortised in the yoke-like top rail. While the design of the back splat exercised a foundation for English chairs within the Queen Anne period, wooden members that only just to a restricted extent support corner joints (and furthermore are loose to top that off) indicate an element solely to Chinese chairs. The four legs are set through the seat frame, which stops over the rounded staves. Each member is round in section or have rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is uncomfortable and may have a plaited texture. These chairs required the sitter to be stiff and upright; when too much weight is pushed on the back, the chair has a tendency to collapse. In patriarchal Chinese homes of this epoch armchairs presumably were allowed only for elderly individuals, for they were held in great respect.

The Chinese folding stool is presumed to have come to China from the West. It is akin very much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is elegantly fixed to the two legs of the stool by a curved member, which is often provided with metal mounts. From a Western perspective the resulting effect of both furniture items is stylized. The construction and decorative elements are combined in a manner that is all at once both naïve and refined. The patchwork appearance is an upshot of the manner that the individual members do not appear to have been adjoined by either glue or screws, but had been mortised into one another and held in position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also put its name on the chair. Artworks project a design of chair with a relatively crude wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing between, stitched to show up a pattern of tiny pads. The front board and a similar board in the back could be folded after unscrewing some little iron hooks. Therefore the chair was a portable piece of furniture when traveling which, during the same era, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be evidenced in engravings of the interior of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair is also seen in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not decided that the form actually was born in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of slim measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was manufactured in impressive amounts, as can be seen from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up against a wall. The form asserts itself by virtue of 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 of forms—that was, as created in Paris around 1750—conquered most of Europe and was imitated or copied into the mid-20th century. The style owes such popularity to a combination of relaxation and elegance. The seat suits to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are strongly constructed on craftsmanlike methodology in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of quite thick dimensions; but each member is deeply molded, all extra wood has been sanded away, and more upmarket chairs can be further embellished with highly delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all upholstery on the seat, back, and armrests; cane is sometimes used instead of upholstery.

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

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

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

In cheaper styles 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.

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, suggest that completely new chair forms will probably be evolved in the future.

Essentially, bookkeeping grants 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 enterprise from a given period.

Management officials, investors, and credit grantors all require this information: management in order to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to analyse the results of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to analyze the financial statements of a business in assessing whether to accept a loan.

Bits and pieces of financial and numerical recordkeeping have been uncovered for just about every society with a commercial history. Records of trade contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The double-entry manner of bookkeeping started with the development of the commercial republics of Italy, and tutorial manuals for bookkeeping were created in the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial books a necessity. The past of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, partially, assisted in forming it. The international spread of industrial and commercial activity required more professional decision-making processes, which in turn demanded more sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government regulation became more important and resulted in greater requirement for information; firms 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 became sizeable, and the demand for bookkeeping for their own departmental operations went up.

While bookkeeping procedures can be rather detailed, all of it is based on two kinds of books employed in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so on), and the ledger must have the records of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The point of the income statement or profit-and-loss statement is to provide an analysis of the changes that have occurred in the entity equity from the events of the period. The balance sheet gives the financial situation of the entity at a particular day in terms of assets, liabilities, and the ownership equity.

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.
