Solar System consists of the Sun and the other space objects gravitationally bound to it: the eight planets, their 162 known moonsthree currently recognized dwarf planets (including Pluto) and their four known moons, and billions of small bodies. This last group includes asteroids, Kuiper belt objects, comets, meteoroids and interplanetary dust.
In wide terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, collected of icy objects. Beyond the Kuiper belt lies the scattered disc, the heliopause, and eventually the hypothetical Oort cloud.
In sort of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Six of the eight planets are in turn orbited by natural satellites, usually termed "moons" after Earth's Moon, and each of the outer planets is encircled by planetary rings of dust and other particles. All the planets apart from Earth are named after gods and goddesses from Greco-Roman mythology. The three dwarf planets are Pluto, the largest known Kuiper belt object; Ceres, the largest object in the asteroid belt; and Eris, which lies in the scattered disc.

Society
A society is a grouping of individuals, which is characterized by common interests and may have distinctive culture and institutions. In a society, members can be from a different ethnic group. A "Society" may refer to a particular people, such as the Nuer, to a nation state, such as Switzerland, or to a broader cultural group, such as a Western society. Society can also refer to an organized group of people linked together for religious, benevolent, cultural, scientific, political, patriotic, or other purposes.

Fishing
Fishing is the activity of hunting for fish by hooking, trapping, or gathering. By extension, the term fishing is applied to pursuing other aquatic animals such as various types of shellfish, squid, octopus, turtles, frogs, and some edible marine invertebrates. The term fishing is not usually applied to pursuing aquatic mammals such as whales, where the term "whaling" is more appropriate. Fishing is an ancient and worldwide practice with various techniques and traditions and it has been transformed by modern technological developments. In addition to providing food through harvesting fish, modern fishing is both a recreational and professional sport.

Kolkata
Calcutta is the capital of the Indian state of West Bengal. It is located in eastern India on the east bank of the River Hooghly. The city has a population of almost 11 million, with an extended metropolitan population of over 14 million, making it the third-largest urban agglomeration and the third-largest city in India.
The city was very populated and served as the capital of India during the British Raj until 1911. Once the centre of modern education, science, culture and politics in India, Kolkata witnessed economic stagnation in the years following India's independence in 1947. However, since the year 2000, an economic rejuvenation has arrested the morbid decline, leading to a spurt in the city's growth. Like other large cities, Kolkata continues to struggle with urbanisation problems like poverty, pollution and traffic congestion.
A vibrant city with a distinct socio-political culture, Kolkata is noted for its revolutionary history, ranging from the Indian struggle for independence to the leftist and trade union movements.

Batteries
Electronic watches require electricity as a power source. Some mechanical movements and hybrid electronic-mechanical actions also require electricity. Usually the electricity is provided by a replaceable battery.
The first use of electrical power in watches was as replacement for the mainspring, in order to remove the need for winding. The first electrically-powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania. Batteries for watches are specially designed for their purpose. They are very small and provide tiny amounts of power incessantly for very long periods. In most cases, replacing the battery requires a trip to a watch-repair shop or watch dealer; this is especially true for watches that are designed to be water-resistant, as special tools and procedures are required to ensure that the watch remains water-resistant after battery replacement. Silver-oxide and lithium batteries are popular today; mercury batteries, formerly quite common, are no longer used, for ecological reasons. Cheap batteries may be alkaline, of the same size as silver-oxide but providing shorter life.

Nutrition
Nutrition is a science which studies the relationship between diet and states of health and disease. Dietitians are Health professionals who are particular in this area of expertise. They are also the only extremely trained health professionals able to provide safe, evidence-based and accurate dietary advice and interventions.
Between extremes of optimal health and death from starvation or malnutrition, there is an array of disease states that can be caused or alleviated by changes in diet. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as scurvy, obesity or osteoporosis, as well as mental and behavioral problems. Moreover, excessive ingestion of elements that have no apparent role in health, (e.g. lead, mercury, PCBs, dioxins), may incur toxic and potentially lethal belongings, depending on the dose. The science of nutrition attempts to understand how and why exact dietary aspects influence health.

Joystick
A joystick is a personal computer tangential or general control device consisting of a handheld stick that pivots about one end and transmits its angle in two or three dimensions to a computer. Joysticks are often used to control video games, and generally have one or more push-buttons whose state can also be read by the computer. The term joystick has become a synonym for game controllers that can be connected to the computer since the computer defines the input as a "joystick input”. Apart for controlling games; joysticks are also used for controlling machines such as elevators, cranes, trucks, powered wheelchairs and some zero turning radius lawn mowers. More lately miniture joysticks have been adopted as navigational devices for smaller electronic apparatus such as mobile phones.

Metal
In chemistry, a metal is a constituent that readily loses electrons to form positive ions and has metallic bonds between metal atoms. Metals form ionic bonds with non-metals. They are sometimes described as a web of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as eminent by their ionization and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron separates the metals from the nonmetals. Most elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals.
A modern definition of metals is that they have overlapping conveyance bands and valence bands in their electronic structure. This definition opens up the category for metallic polymers and other organic metals, which have been prepared by researchers and employed in high-tech devices. These synthetic materials often have the characteristic silvery-grey reflective ness of elemental metals.

Finance
Finance studies and addresses the ways in which individuals, businesses, and organizations raise, allocate, and use financial income over time, taking into account the risks entailed in their projects. The term finance means the study of money and other assets; the activity of finance is the relevance of a set of techniques that individuals and organizations (entities) use to control their financial affairs, particularly the differences between income and expenditure and the risks of their investments.
An entity whose income exceeds its expenditure can lend or invest the excess income. On the other hand, an entity whose income is less than its expenditure can raise assets by borrowing or selling impartiality claims, decreasing its expenses, or increasing its income. The lender can find a borrower, a financial intermediary, such as a bank or buy notes or bonds in the bond market. The lender receives interest, the borrower pays a higher interest than the lender receives, and the financial intermediary pockets the difference.
Finance is used by individuals (personal finance), by governments (public finance), by businesses (corporate finance), etc., as well as by a broad variety of organizations including schools and non-profit organizations. In general, the goals of each of the above activities are achieved through the use of suitable financial instruments, with consideration to their institutional setting.
Finance is one of the most important aspects of business management. Without proper financial planning a new enterprise is unlikely to be successful. Managing money is essential to guarantee a secure future, both for the individual and an organization.

Nanotechnology
Nanotechnology is a pasture of applied science and technology covering a wide range of topics. The main unifying premise is the control of matter on a scale smaller than 1 micrometer, normally between 1-100 nanometers, as well as the manufacture of devices on this same length scale. It is a highly multidisciplinary field, drawing from fields such as colloidal science, device physics, and supra molecular chemistry. Much hypothesis exists as to what new science and technology might result from these lines of research. Some view nanotechnology as a marketing term that describes pre-existing lines of research applied to the sub-micron size scale.
In spite of the apparent ease of this definition, nanotechnology actually encompasses diverse lines of inquiry. Nanotechnology cuts across many disciplines, together with colloidal science, chemistry, applied physics, materials science, and even mechanical and electrical engineering. It could variously be seen as an extension of existing sciences into the Nanoscale, or as a recasting of existing sciences using a newer, more recent term. Two major approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built from molecular components which gather themselves chemically using principles of molecular gratitude; the other being a "top-down" approach where nano-objects are constructed from larger entities without atomic-level control.

Dot matrix printer
Not like a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced. Because the printing involves mechanical pressure, these printers can create carbon copies and carbonless copies. A dot matrix printer or impact matrix printer refers to a type of computer printer with a print head that runs back and forth on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like a typewriter.
Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which uses the power of a tiny electromagnet or solenoid to drive it forward, either directly or through small levers. Facing the ribbon and the paper is a small guide plate pierced with holes to serve as guides for the pins. The moving portion of the printer is called the print head, and prints one line of text at a time. Most dot matrix printers have a single vertical line of dot-making equipment on their print heads; others have a few interleaved rows in order to improve dot density.
These machines can be highly hard-wearing, but eventually wear out. Ink invades the guide plate of the print head, causing grit to adhere to it; this grit slowly causes the channels in the guide plate to wear from circles into ovals or slots, given that less and less accurate guidance to the printing wires. After about a million characters, even with tungsten blocks and titanium pawls, the printing becomes too indistinct to read.

Croydon Airport
Croydon Airport is in south London on the borders of the London Boroughs of Croydon and Sutton. It was once the main airport for London, before it was replaced by Northolt Aerodrome, London Heathrow Airport and London Gatwick Airport.It originated as two adjacent World War I airfields. Beddington Aerodrome, one of a number of small airfields around London which had been formed for protection against the Zeppelin raids in about May 1915, and Waddon Aerodrome of 1918, a test-flight aerodrome adjoining National Aircraft Factory No1.At the end of that war, the two airfields were joint into London's official airport as the gateway for all international flights to and from the capital. Croydon Aerodrome opened on 29 March 1920.It stimulated a increase in regular scheduled flights carrying passengers, mail and freight, the first destinations being Paris, Amsterdam and Rotterdam. In 1923 Berlin flights were added. It was the operating base for Imperial Airways - remembered in the road name Imperial Way on the site today.In the mid 1920s, the airfield was extended, some adjacent roads being permanently closed to allow heavier airliners to land and depart safely. A new complex of buildings was constructed adjoining Purley Way, including the first purpose-designed air terminal in the world, the Aerodrome Hotel and extensive hangars, all opening on 2 May 1928.The terminal building, the booking hall inside it with its gallery balustraded in the geometrical design typical of the period, and the Aerodrome hotel were all built in the Art Deco style of the 1920s and 1930s. A further item that caught the eye of visitor and traveller alike was the time zone tower in the booking hall with its dials depicting the times in different parts of the world.The aerodrome was known the world over, its fame being spread by the many aviators and pioneers who touched down at Croydon.

Postage Stamp
A postage stamp is proof of pre-paying a fee for postal services. Usually a small paper rectangle which is attached to an envelope, signifying that the person sending the letter or package has paid for delivery; it is the most popular option to using a prepaid-postage envelope.
History
In it he argued that it would be well again for the sender to pay the cost of delivery, rather than the addressee who could refuse the letter if they could not or did not want to pay, as occasionally happened at the time. He also argued for a identical rate of one penny per letter, no matter where its end. Accounting costs for the government would thus be cut; postage would no longer be charged according to how far a letter had traveled, which necessary each letter to have an individual entry in the Royal Mail's accounts. Chalmers' ideas were finally adopted by Parliament in August, 1839 and the General Post Office launched the Penny Post service the next year in 1840 with two prepaid-postage symbolic envelopes or wrappers: one valued at a penny and one valued at two pence.

Clock face
100 A clock faces is the part of an analog clock that tells time from side to side the use of a fixed numbered dial or dials and moving hand or hands. Typically, the dial is numbered 1-12 representative the hours in a 12-hour cycle. The term face is also used for the time display on digital clocks and watches.
Certain clocks have 24-hour analog displays and are noticeable consequently. Some special purpose clocks, such darkroom timers and sporting occasion clocks are designed for measuring periods less than one hour. Clocks can indicate the hour with roman numerals or Arabic numerals. The two numbering systems have also been used in mixture with the prior representing the hour and the later the minute. Long case clocks typically use Roman numerals for the hours. Clocks using only Arabic numerals first began to appear in the mid-18th century. In some instances, mainly in the case of watches, the numbers are replaced with undifferentiated hour markings. Infrequently markings of any sort are dispensed with. The face of the Movado "Museum Watch" is known for a single dot at the 12 o'clock position.
Historical and Stylistic Development
Before the late 15th century, a fixed hand indicated the hour by pointing to rotating numbers. Minute hands only came into use in the late 17th century after the discovery of the pendulum allowed for increased accuracy in time telling. Until the last quarter of the 17th century hour markings were etched into metal faces and the recesses filled with black wax. Subsequently, higher contrast and improved readability was achieved with white enamel plaques painted with black numbers. Initially, the numbers were printed on small, individual plaques mounted on a brass substructure. This was not a stylistic decision; rather enamel production technology had not yet achieved the skill to create large pieces of enamel. The "13 piece face" was an early attempt to create an completely white enamel face. As the name suggests, it was composed of 13 enamel plaques: 12 numbered wedges en suite around a circle. The first single piece enamel faces, not unlike those in production today, began to appear c. 1735.

Sunglasses
Sunglasses are a kind of visual correction aid, variously termed spectacles or glasses, which feature lenses that are coloured or darkened to screen out strong light from the eyes.Many people find direct sunlight too bright to be comfortable, particularly when reading from paper on which the sun directly shines. In outdoor activities like skiing and flying, the eye can receive more light than usual. It has been recommended to wear these kind of glasses on sunny days to protect the eyes from ultraviolet radiation, which can lead to the development of a cataract. Sunglasses have also been linked with celebrities and film actors mainly due to the desire to mask identity, but in part due to the lighting involved in production being typically stronger than natural light and uncomfortable to the naked eye.Augusto Pinochet sits with sunglasses in the front of the Chilean JuntaContents

British coinage
Obverse and turn around of ordinary coins in current movement, £2, £1, 50p, 20p, 10p, 5p, 2p and 1pThe British currency was decimalized on February 15, 1971. The basic unit of currency – the Pound – was unchanged. Previous to decimalization there were 240 pennies in a pound, now there are 100 new pence. The new coins were noticeable with the wording "New Penny" or "New Pence" to discriminate them from the old. The word new was drop after ten years. The representation p was also adopted to tell apart the new pennies from the old, which used the sign d.
The initial pound coin was introduced in 1983 to replace the Bank of England £1 banknote which was discontinues in 1984. A circulating bimetallic £2 coin was also introduced in 1998– there had until that time been remembrance £2 coins which did not normally circulate. The total amount of coinage in exchange is approximately three and a quarter billion pounds, of which the £1 and £2 coins account for almost two billion pounds.
Every year, newly mint coins are checkered for size, weight, and work of art at a Trial of the Pyx. Fundamentally the same process has been used since the thirteenth century. Assay is now done by the Worshipful Company of Goldsmiths on behalf of HM Treasury.

The Honda History
In 1997 Honda begins produce a street-oriented GT motorcycle using an in history significant name: Super hawk. The earlier Super hawk was a similar twin motorcycle that Robert M. Pirsing rides in "Zen and the Art of Motorcycle Maintenance". The unique Super hawk was a profitable achievement, therefore the name being recycled. The new Super hawk was introduced after the Ducati 916 made V-twin sport bikes popular again. The fresh Super hawk uses an all new 90 degree V-twin. The bike bring in a number of fresh design concept such as the "pivot less frame", side radiators, single cast engine case, connecting rods with cap screw in its place of nuts, and the major carburetors Honda ever put on a motorcycle. "Pivot less frame" inevitable that engine was a harassed member with the swing arm bolted directly to the engine. The bike was released in 1997 as an early release 1998 model year. One motorcycle magazine recommended that this bike was the fastest 0-60 mph manufacture bike at the time. A racing version of the bike was predictable from Honda. Honda formed in 2000 the RVT1000R known outside the United States as the VTR1000SP, although the bike had only four engine parts in common with the modern Super hawk. The RC51 was an completely new V-twin racing platform that won the World Super bike championship its first year race through Colin Edwards and the Castrol team.

Longships
Longships, langskip or drakkar were boats used by the Scandinavians and Saxons for their raids on costal and inland settelments. They were the epitome of Scandinavian military power and ranked extremely as precious material possessions.
The longship was a long, narrow, light boat with shallow draft, with oars along approximately the entire length of the boat. Later versions sported a rectangular sail on a single mast to augment the rowers particularly during longer journeys. In combat the variabilily of wind power made rowers the chief means of propulsion. virtually all longships were clinker built and waterproofed by moss drenched in tar. The ship's low mass and shallow keel permitted navigation in waters just 1 meter deep, rapid beaching when landing on beaches, and portage over land.
Construction
Our best evidence for longship building comes from ship-burials. It was common in Viking society for kings to be buried under a long burial mound in a ship with rich possessions. The Oseberg ship burial in Norway and the Anglo Saxon longship of Sutton Hoo in England are both good examples.
Longships were extraordinarily narrow for their length compared to modern standards The main discovered longship (at Roskilde harbor) is 35m in length, and the longship from Hedeby harbour has the largest length/width proportion: 11.4 to 1. However, later longships, optimized for sailing, had lower ratios, often 1 to 7 or even 1 to 5.
In contrast, Scandinavian trade ships or knarrs were built deeper and broader to accommodate bulkier cargo, and were more reliant on sails. A similar relationship may be seen in Mediterranean galleys, which are now and then called longships as well, and their merchant vessels, which were roundships.
Rectangular sails made of wool strengthened by leather were introduced later. Under sail, longships were very fast, achieving speeds of 14 knots. They were also extremely seaworthy, but, being essentially open boats, not very habitable. However, this did not stop early Scandinavian explorers from discovering and settling in Iceland, Greenland, and Canada, all well before Christopher Columbus landed in the Bahamas in 1492.
