• WHAT IS THE ‘COOL BIZ' CAMPAIGN?

This is a campaign introduced by Japan. In order, to save energy, it asks office goers and politicians to remove their ties and jackets to minimise the use of air conditioners and thereby reduce consumption of electricity and also the emission of greenhouse gases. German Chancellor, Angela Merkel who is currently visiting Japan to discuss, among other things, ways to tackle global warming, had a taste of the 'cool biz' campaign when the Japanese Prime Minister Shinzo Abe informed her that his entourage wouldn't be wearing their ties to adhere to the 'cool biz' campaign.

• WHAT IS A CIRCUIT FILTER?

A circuit filter is used in trading of shares in stock exchange. It's applied to all the shares, to supposedly safeguard the interest of general investors from the extreme volatilities in markets by preventing any unexpected fall or rise of share price in a single day beyond a limit. If the limit is crossed by any of the shares in a single trading day it is frozen for trade.

• WHAT IS THE GINI COEFFICIENT?

The Gini Coefficient is a measure of inequality of income distribution or inequality of wealth distribution. It is defined as a ratio with values between 0 and 1: the numerator is the area between the Lorenz curve of the distribution and the uniform distribution line; the denominator is the area under the uniform distribution line. Thus, a low Gini Coefficient indicates more equal income or wealth distribution, while a high Gini Coefficient indicates more unequal distribution.

• WHAT IS THE TRIPLE FINGER SALUTE?

The three-finger salute is used by members of Scouts and Guides organisations around the world when greeting other Scouts and Guides and at some ceremonies. The salute is made with the palm face out, the thumb holding down the little finger, and the fingertips on the brow. In computer parlance, the triplefmger salute refers to describe the three-key sequence — Alt + Ctrl + Del — developed by David Bradley This term became popular after IBM PC compatible users continually hold down these keys each time their computers froze or had other problems.

• WHAT IS REFERRED TO AS THE WELL-COME COLLECTION?

• WHAT IS KNOWN AS THE BAUDHAYAN THEOREM?

Baushayan Sulv Sutra (1000 BC) is today known as the Pythogorus theorem, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In Baudhayan theorem, this has been expressed as follows: in a Deerghchatursh (triangle), the chetra (square) of rajju (hypotenuse) is equal to the sum of squares of the parshvamani (base) and triyangmani (perpendicular line). It is amazing to note that the pythagorus theorem was known in our country as far back as 1000 BC.

• WHY IS THE NUMBER 1 NOT CONSIDERED A PRIME NUMBER THOUGH IT FITS THE DEFINITION?

The number 1, in fact, does not fit the definition of a prime number. A positive integer is called a prime number only if there are exactly two divisors of that number. Since 1 has exactly one divisor (which is 1 itself), it does not fit this definition. Another equivalent definition of a prime number is this prime number's only positive divisor should be less than 1 and itself. Again, 1 does not fit this definition either— there are no positive divisors of 1 which are less that 1.

• WHICH NATION HAS THE SMALLEST ARMY IN THE WORLD?

Vatican City, the world's smallest country, has the smallest army. This army of 110 men, is also known as the Swiss Guard. Last year, the Vatican celebrated the 500th anniversary of the Swiss Guard. The celebration commemorated the 150 Swiss Helvetian mercenaries who came to Rome to serve Pope Julius II, on January 22,1506. The mercenaries covered a distance of 723 km in 27 days to enter Rome from Bellinzona, Switzerland. Swiss Helvetian mercenaries, famous for their courage, die-hard attitude and loyalty to their employers, were part of the regular armies of various countries at that time. As allies of the Pope, they helped to shape Italy's destiny and thus they were granted the title ^Defenders of the Church's freedom' by the Pope. During the Sack of Rome on May 6, 1527, the Swiss Guard, comprising 189 personnel at that time, resisted a Spanish attack on Rome and the Vatican. But they had to retreat after suffering heavy casualties. Only 42 men survived the attack. However, the Guard was able to ensure Pope Clement VII's escape to safety.

• WHERE WAS WINE FIRST MADE?

Wine is the fermented juice of grapes. Probably, the first people to make wine were Persian farmers living near the Caspian Sea. The Egyptians learned how to make wine from them as long back as 3000 BC. In the fourth century BC., the Greek conqueror Alexander the Great carried grapevines and the knowledge of wine-making to Central Asia. Roman invaders probably took vines to northern France and Germany in later centuries. Wine was common in the everyday lives of the early Greeks and Romans. It was important to their religious ceremonies. The God of wine was called Bacchus by the Romans and Dionysus by the Greeks.

• WHAT IS THE DIFFERENCE BETWEEN MARXISM AND SOCIALISM?

Socialism is a modern doctrine and is Western in origin, emerging with the development of industrial capitalism at the start of the nineteenth century. Socialism denotes a broad system of ideas. Marxism is a materialistic conception of history which seeks to explain the development of all societies and furthermore, make predictions about future social change. Marxists consider the material world, nature and society as constantly moving. Whereas, the socialists emphasise the organic unity of society. Marxists consider the material world as an integrated whole in which all things and phenomena are interconnected and interdependent. Whereas, socialists believe in equality and abolition of private enterprise. Marxism provides a scientific explanation of nature and society and hence, was a powerful instrument for revolutionary transformation. The society envisaged by socialists rests on certain values: redistribution of wealth to get rid of inequality, cooperative production to get rid of selfish competitors and new patterns of work and education to promote the growth of well-rounded individuals.

• WHAT IS A HYPERCUBE?

Hypercube is the generalization in n-dimensions of a square in two dimensions and a cube in three dimensions. A square has four vertices (22), a cube, 8 vertices (23). Similarly, an n-dimensional hypercube has 2n vertices. In the famous painting 'Christus Hypercubus', Salvador Dali depicted Christ crucified on an unfolded four-dimensional hypercube. Examining the shadow of a cube reveals a square within a square. Similarly, the shadow of a four-dimensional hypercube will be a cube within a cube.

• WHY IS THE ALPHABET WRITTEN IN A SPECIFIC ORDER?

The alphabet has often been described as an arbitrary collection of symbols representing an arbitrary collection of sounds. Its order is equally random. The word alphabet comes from alpha and beta, the first two words in the Greek alphabet.

• WHAT IS STEAMING DISTANCE?

Steaming distance is the shortest distance between two ports, which a ship traverses while sailing from one port to another. It need not be along a straight line as, due to various physical and political constraints, it may not be always be desirable to sail along a straight route.

• WHICH IS THE OLDEST CIVILIZATION IN THE WORLD?

This has long been a subject of much debate and to this day no one is absolutely sure which is the oldest civilisation. This is mostly because people cannot agree on the definition of the word civilisation. The most common definition of the word is 'an advanced state of development in human society, marked by progress in the arts and sciences, the extensive use of writing, and complex political and social institutions'. Mesopotamia is considered as the most likely answer to the question, based on archaeological evidence and the above definition. It is believed that Mesopotamian history starts from the emergence of urban societies in Southern Iraq in the 4th millennium.

• HOW IS A COUNTRY'S GDP MEASURED?

GDP or Gross Domestic Product is the monetary value of all the finished goods and services produced within a country's borders in a specific time period. GDP is customarily reported on an annual basis. It is the nation's broadest gauge of economic health. It includes all of private and public consumption, government outlays, investments and exports and imports that occur within a defined territory The most common approach to measuring GDP is the expenditure method: GDP = consumption + investment (govern- ment spending) + (exports - imports). Another way of measuring GDP is to measure the total income payable in the GDP income accounts. This should provide the same figure as the expenditure method. Another formula is: GDP = rent + interests + profits + statistical adjustments (like corporate income taxes, dividends, undistributed corpo-1 rate profits) + wages.

• WHAT IS SPECIAL ABOUT UNIVERSITY OF TOULOUSE?

University of Toulouse is one of the oldest universities of France and is located in Toulouse, a city in Southern France on the banks of the Garonne river. It was founded in 1229 AD as a result of the Paris Treaty marking the end of the battle between the Roman Catholic Church and its opponents. Foulques de Toulouse, the then bishop of Toulouse, played a major role in the setting up of the university. Now, the university has an enrolment exceeding 1,00,000, and is the second largest university in France. The sixteenth century philosopher and astronomer Bruno and the Chemistry Nobel Laureate Sabatier, and the artist Dulac were some of its most illustrious faculty members.

• IN ANCIENT TIMES, WHY WERE PIGEONS USED FOR SENDING MESSAGES?

Pigeons were used for sending messages not only in ancient times, but as recently as early the 1900s, during World War I. A particular breed of pigeons called homing pigeons are specially suited for carrying messages, because they possess the uncanny ability of flying back to their home over long distances at high speeds. According to some reports, a homing pigeon flew back to its home after flying over 1600 miles at the peak speed of 60 miles per hour. Exactly how such birds navigate themselves is still not clear. Scientists hypothesise that the pigeon uses a variety of sources like the direction of the Sun, Earth's magnetism, and odours associated with different places for finding its direction. Before the advent of telegraph, telephone and radio, using pigeons for sending messages was quite popular among the military, newspapers, and stock brokers. Such a messaging system was known as pigeon post.

• WHAT IS AN ATLAS CALLED SO?

Atlas is the term used to refer to a collection of maps, printed in a set order: world map, maps of the continents, each followed by maps of the several regions within that continent, and with an alphabetical gazetteer or list of place names, giving coordinates for various places, rivers, regions etc. The first use of the term atlas dates back to 1595 with the publication in Duisburg of the Atlas Sive Cosmographicae Meditationes de Fabrica Mundi Et Fabricati Figura by Gerard Mercator (1512-94). It was named after King Atlas, a mythical King of Mauretania in Libya, who was, according to legend, a wise philosopher, mathematician and astronomer and who supposedly made the first celestial globe. However, the more widely known Atlas is a figure from Greek mythology He is the son of the Titan lapetus and Clymene^or Asia), and brother of Prometheus. Atlas was punished by Zeus and made to bear the weight of the heavens and Earth on his back.

• WHAT IS THE ORIGIN OF THE TERM 'RULE OF THUMB' ?

One theory about the phrase's origin lies in the misplaced public belief that the English law allowed a man to beat his wife with a stick measuring no longer than his thumb. There was actually no such English law enacted at any time. This phrase has been in circulation since the 17th century This phrase commonly refers to any means of estimation based on a practical and ready method but not on scientific measurement. Another theory concerning the phrase's origin involves the numerous ways in which thumbs have been used for estimation. Some examples are — measurement of distance based on an estimated inch which is about the length of a thumb; judging the alignment or distance of an object by holding the thumb at eye level etc.

• WHAT IS RED CORNER NOTICE?

It is a landlocked sovereign city state whose territory consists of a walled enclave within the city of Rome. It is officially called State of the Vatican City.

• WILL CREATING TWO TIME ZONES FOR INDIA SAVE ENERGY?

There is no statistical evidence of two time zones being economically beneficial other than restoring a sense of normalcy to the area that follows its local meridian time zone. India geographically extends from 68 degrees East to 97 degrees East (29 degrees) from Gujarat to the Andaman & Nicobar Islands, thereby encompassing two time zones. However, it has adopted the Allahabad meridian of 72 degrees, which makes it convenient for the railways, airlines and media. This leads to weird experiences for travelers from Central India who visit the North-Eastern states which receive daylight before 5 am. This entails an extra cost to the economy in terms of industrial arid office lighting spent in these regions, since daybreak here doesn't coincide with the rest of the country. Also, there tends to be more traffic when it is dark.

• IS IT TRUE THAT CREATING TWO TIME ZONES FOR INDIA WILL SAVE ENERGY?

The Indian Standard Time is based on the meridian at 82 1/2 degrees East, which is 5 1/2 hours ahead of the Greenwich meridian. India's geographical middle lies at 82 1/2 degrees East, which was incorrectly mentioned as 72 degrees East.

• WHAT IS SECURITISATION?

Securitisation is the process through which existing assets or future cash flows are converted into marketable securities. Those assets or cash flows are, inherently, not marketable. There are two types of securitisation — assetbacked securitisation and futureflows securitisation. Some of the assets that can be securitised are loans and future cash flows like credit card payments, car rentals or any other form of future receivables. Securitisation is common in the US and Europe, but in India it is in a nascent stage.

• WHEN AND WHERE WAS THE NEWSPAPER PUBLISHED?

Acta Diurna' was the first news paper published in Rome, around 59 BC. In 1605, the first printed weekly newspaper to be published in Antwerp was called Relation. Johann Carolus (1575-1634) was the publisher of the Relation aller Furnemmen und gedenckwurdigen Historien (Collection of all Distinguished and Commemorable News). The ^Relation' is recognized by the World Association of Newspapers, as well as many authors, as the world's first newspaper. The German Relation was published in Strasbourg, which had the status of an imperial free city in the holy Roman empire of the German nation.

• WHEN WAS THE BATTLE OF LOS ANGELES?

The Battle of Los Angeles took place during the night of February 24/25, 1942 in Los Angeles, California. The battle involved heavy firing of anti-aircraft shells by the US forces aimed at several mysterious flying objects reportedly sighted in the sky over Los Angeles. These objects were thought to be Japanese military aircraft. However, even till today, their identity has not convincingly established. Even though six civilians lost their lives in the bombardment, there was no evidence that the firing destroyed any flying object. The firing was preceded by a blackout and Sounding of air raid sirens. Now, many believe that the battle was the result of a false alarm, triggered by weather balloons, or Japanese blimps. Some even think the source of the alarm could be a flying object of extraterrestrial origin.

• WHO IS LADY JUSTICE?

The origin may be Themis, a Greek mythological goddess, who advised Zeus after his purge of the old pantheon. A daughter of Themis and Zeus, Dike, known as a goddess of justice but not divine justice, presided over the apportionment of things among mortals, the protection of individuals and the social and political order. At times, Dike is said to be the same as (or is confused with) Astraea. Astraea is also a daughter of Themis and Zeus and is known as a goddess of justice. In western tradition, Lady Justice sometimes wears a blindfold and carries a sword and scales. She symbolises the fair and equal administration of the law, without corruption, avarice, prejudice, or favour.

• WHO ARE HOBOS?

Hobos is an American word which refers to homeless people wandering about in search of work. In earlier days, hobos were supposed to move around by hopping from one freight train to another, just to save the cost of transportation. Hobos and hobo culture began in mid-19fh century, when the ending of the Civil War caused severe unemployment in the US and several people left their homes and started moving about the whole country in search of jobs. A similar phenomenon happened during the Great Depression of the 1930s. Although the term owes its origin to the above phenomena, it is used today to refer to a tramp in general, an aimless traveller not necessarily looking for work. There are several theories related to how the word hobo got coined: some say the word has been derived from the phrase hopping box cars, and some others that it is a shortened version of the rail-road greeting 'Ho Beau,' popular in the 19th century

According to the museum, this post office has functioned continuously since 1712 AD. Sanquhar is a quiet, insignificant town, but in its heyday, its residents included many influential aristocrats, who must have played a significant role in having the first post office located there. Those days, horses and stage coaches would carry mail.

• WHAT IS A CALLIOPE?

It is a musical instrument with a loud, shrill sound that's audible miles away It is used to attract attention at circuses and fairs. It was invented in the United States around 1850 by A S Denny and patented in 1855 by Joshua C Stoddard. It consists of a boiler which forces steam through a set of whistle pipes.

Chopsticks were made over 5,000 years ago in China. The earliest version of chopsticks were plain sticks or branches from trees which were used to retrieve food from fire. The teachings of Confucius forbade followers to use knives at the dining table, which further increased the popularity of chopsticks in Eastern Asia. Today, chopsticks are no longer confined to culinary purposes. Japan has even launched a bra called 'My Chopsticks Bra' which is made from recycled chopsticks. This would reduce the decimation of entire forests to manufacture chopsticks.

• WHAT IS A ‘BREATHING FABRIC'?

A 'breathing fabric' is designed to prevent the wearer from getting too hot or cold by adjusting itself to both the internal and external temperatures. The textile is made up of a layer of thin spikes of wool, or another water-absorbent material that opens up when it's made wet by the wearer's sweat.

• WHAT CAUSES THE HEILIGENSCHEIN EFFECT? WHO DISCOVERED IT?

If an observer stands on dew-covered grass with his or her back turned towards the early morning sun, the observer is likely to observe a faint glow around the shadow of his or her head on the grass. Such a faint glow is called Heiligenschein, and the above optical phenomenon, the Heiligenschein effect. It occurs because the dew droplets act as tiny lenses focusing both the sunlight falling on the surface on which the shadow is cast, and the light that is back-scattered by the surface. In general, when a long shadow is cast on certain irregular surfaces with specific optical characteristics, the above effect occurs. Although Heiligenschein must have been known for a long time, it was first described in writing by the Italian sculptor and painter Benevenuto Cellini (1500-1571). Sometimes it's called the Cellinis halo. In German, Heiligenschein means holy glow.

• WHAT ARE THE OLEFINS?

An alkene, olefin or olefine is a class of highly reactive unsaturated hydrocarbons, recovered from petroleum, with at least one carbon-carbon double bond. The simplest alkenes, with only one double bond and no other functional groups, form a homologous series of hydrocarbons with the general formula CnH2n, eg. Ethylene (ethane), propylene (propene), butylenes (butene) and so on. The olefins are widely used for making synthetic fibres.

• WHO BROKE THE SOUND BARRIER?

Chuck Yeager broke the sound barrier on October 14,1947. He flew a plane faster than the velocity of the sun and broke the sound barrier which caused explosive vibrations over the atmosphere.

• WHAT IS THE MONTY HALL PROBLEM?

The Monty Hall problem talks about a situation where there are three closed doors —a goat lies behind two and a car behind the third. A person is asked to select a door (which is not opened immediately). Instead, one of the two unchosen doors are opened and the content is revealed, which incidentally turns out to be a goat. The person is now asked whether he would like to switch his choice to the other unopened door. This gets him thinking. Will changing his choice increase the possibility of winning the car? Common knowledge lets us assume that since now there are two closed doors (one with a goat and the other with a car), chances of winning a car if either of the doors are chosen is 1/2. Hence, it really isn't a winning situation to motivate a person to change the choice. However, what one needs to remember is the fact that when the person initially made the choice, all three doors were closed and the probability of having a goat behind a closed -toor was 2/3. Now that we already know of ie door that has a goat behind it, chances f winning the door with the car if the peron decides to change his initial choice is /3, which is higher than what he would am if he refuses to change his decision.

• WHO INVENTED THE HELICOPTER?

French inventor Launoy and Bienvenue created a toy with rotary wings which could take off vertically and fly The term helicopter was later coined by French writer Ponton D'Amecot: helico for spiral and pter for wing.

The earliest way of telling the time was by looking at the progress of the shadow cast by a twig stuck up-right in the ground. Round about 1300 BC, this was developed by the inhabitants of ancient Egypt and Mesopotamia into the sundial. The sundial served for a thousand years until the invention of the clepsydra, or water clock. This was the first clock with moving parts. The mechanical clock was not invented until the 13th century and it was driven by weights. The spring-driven clock was invented sometime around 1450 AD.

It's also seen as a fallout of the strict population policy of China which restricts couples from having more than one child, because of which parents and relatives tend to spoil their children with fatty foods.

• WHAT WERE GULAG CAMPS?

The Gulag, a system of forced labour camps in the former USSR, was first established in 1919 under the Cheka, its secret police. Prisoners included murderers, thieves, and other common criminals along with political and religious dissenters. The Gulag, whose camps were located mainly in remote regions of Siberia and the far North of USSR made significant contributions to the Soviet economy in the period of Joseph Stalin. Conditions in the camps were extremely harsh. After Stalin died in 1953, the Gulag population was reduced significantly, and condition of inmates somewhat improved.

• WHO IS CHE GUEVARA?

Ernesto Che Guevara was a Cuban revolutionary leader. Though communism may have lost its fire, he remains the symbol of rebellion and the alluring zeal of revolution. By the time Ernesto Guevara, known to us as Che, was murdered in the jungles of Bolivia in October 1967, he was already a legend, not only in Latin America but also around the world. His fearless last words, reportedly, were "Shoot, coward, you're only going to kill a man".

• WHO IS CHE GUEVARA?

Though a comrade of Fidel Castro in the Cuban revolution, Ernesto Che Guevara was actually from Argentina, not Cuba. His nickname 'Che' (loosely translates as 'yaar' in India) is an Argentinian slang.

• WHAT IS THE ORIGIN OF JAZZ MUSIC?

Jazz originated among the Black people in New Orleans in the late 19th century and is characterized by syncopated rhythms and improvisation. It has since developed various styles. Jazz originally drew on Ragtime, Gospel, Black spiritual songs, West African rhythms, and European harmonies. The term jazz originated in southern United States (it is first recorded in 1909, applied to a type of ragtime dance), and it is tempting to speculate that its ancestor crossed the Atlantic on the slave ships from Africa. In the absence of any certain origin, various colourful alternative theories have been put forward, for instance, the name jazz came from the nickname of a certain Jasbo Brown, an itinerant musician along the banks of the Mississippi.

• WHAT IS AGENT ORANGE?

Agent Orange is a defoliant herbicide mixture used during the Vietnam War to destroy forests in Vietnam. The United States sprayed 20 million gallons of Agent Orange over forests in Vietnam, and as a result, members of the armed forces were exposed to it. Agent Orange, named as such due to the orange colour of its storage drums, is a 50:50 mixture of the butyl esters of 2, 4-D and 2,4,5-T. It is probable that damage to humans would be due to the highly toxic impurity dioxin present in Agent Orange.

• HOW OLD IS THE JERUSALEM OLD CITY?

Jerusalem is one of the oldest cities of the world, having a history that begins in the fourth millennium BC. There was a mention of the city even in the Egyptian texts that belonged to 20th century BC. David was the first Jewish king to conquer the city of Jerusalem in 1007 BC and adopt it as his capital. Over the next several centuries, the city has been conquered and ruled by several different groups of people and countries, and has become a holy city for Jews, Muslims and Christians. Today, it is under the control of Israel and happens to be Israel's largest city. What has been the city of Jerusalem until 1860s, is the 0.9 square kilometre walled portion inside the modern city of Jerusalem. The walled portion is called the old city today. The old city is divided into four quarters, Armenian, Muslim, Christian, and Jewish, and houses many important shrines.

• WHO IS KNOWN AS A MATHLETE?

Just as athletes participate in athletic events, matheletes are those who compete in mathematics competitions. The word is a trademark of MathCount Foundation. Recently, a French mathlete named Alexis Lemaire calculated the 13th root of a 200-digit number in just over 70 seconds. By doing so, he beat his own previous record of 72.4 seconds at an event in London's Science Museum.

• WHAT IS A MOM-AND-POP SHOP?

A mom-and-pop shop is a colloquial expression for a single-family operated business with few or no employees other than the owners. Sometimes, fewer than ten employees work in these small or micro businesses. People who speak of mom-and-pop businesses often refer to the unique perspective offered by patronizing a family business. Some encourage the unknown experience of entering a mom-and-pop establishment over franchise businesses, which typically offer comparable stores and similar consumer experiences, regardless of location. For example, mom-and-pop businesses are often highlighted in travel guides, because going to a business owned and operated by a family allows a traveller to fully experience and understand the people of another culture.

• WHO INVENTED CHEWING GUM?

Thomas Adams, a rubber scientist, invented chewing gum. He was working with a substance called chicle, a gum prepared from the latex of the saphodila tree, a tropical evergreen plant. By chance, he popped a small piece of chicle into his mouth and chewed it casually to while away time. Suddenly, it occurred to him that others may derive pleasure from chewing chicle, which is, even today, a chief ingredient in chewing gum.

• WHICH IS THE LONGEST ACRONYM IN USE?

Adcomsubordcomphibspac is the longest English acronym. It's a navy term which stands for Administrative Command, Amphibious Forces, Pacific Fleet Subordinate Command.

• WHAT IS THE DIFFERENCE BETWEEN A FRESCO AND A MURAL?

A mural is any large painting on a wall, ceiling or any other large structure. There are many techniques used to make them. A fresco, executed using water-soluble paints on wet or dry limestone, is one of the techniques and probably the most popular. A primary characteristic of a fresco is that the paintings, though often done in parts, are generally related by a common thread. For example, the frescoes on the walls and ceilings of Ajanta caves in India (6th century) depict the Jataka tales — stories from Buddha's life.

• WHAT DOES THE WORD ‘WOOT' MEAN?

If lay persons say 'yay', then hardcore gamers would say 'wOOt'. This phrase, an expression of joy by on-line gamers, has been selected as the word of the year by the US dictionary publisher Merriam Webster.

• WHAT IS THE NYQUIST RATE?

In data communication, the sampling theorem states that a continuous signal can be completely represented in its sampled form and recovered from the sampled form if the sampling frequency f is equal to 2W, where W is the maximum frequency of that continuous signal. This minimum sampling rate of 2W samples per second for a signal having maximum frequency of W is called the Nyquist Rate.

• WHAT IS THE PHOBIA OF ALIENS CALLED?

Fear or dislike of foreigners or aliens is called xenophobia. The word xenophobia is a combination of two Greek words — xenos (foreigners) and phobos (fear). When a majority of people in a country suffer from xenophobia, the phobia can lead to mass expulsion of people of foreign origin, or banning of certain foreign cultural elements. Xenophobia is different from racism, although often both words are used interchangeably Racism implies a hatred of people of other races, irrespective of whether they belong to one's own country, whereas xenophobia implies hatred of people of other countries or regions. In science fiction, xenophobia refers to fear of extraterrestrial beings. Scientists explain xenophobia as a defence mechanism evolved in humans in response to the need to win in inter-group competition in society and Nature.

• WHAT IS THE GUDERMANNIAN FUNCTION?

The Gudermannian function, named after Christoph Gudermann (1798 -1852), relates to the circular and hyperbolic trigonometric functions without using complex numbers.

• HOW IS A BARGE DIFFERENT FROM A REGULAR BOAT?

The word originally referred to any small boat; the modern meaning arose around 1480. A barge is a flatbottomed boat, built mainly for river and canal transport of heavy goods. Most barges are not self-propelled and need to be moved by tugboats or towboats. Barges on canals contended with the railways in the early industrial revolution but were outclassed when it came to carrying high-value items due to the higher speed, falling costs, and route flexibility of rail transport. A boat is a watercraft designed to float on, and provide transport over water.

• WHAT'S THE GREEN GOLD PROJECT?

The Green Gold or Oro Verde project seeks to ensure the safety of miners and also protect them from exploitation. A jewellery shop in Chichester, England along with miners in a cooperative in Choco in North-East Colombia and the Fair Trade Foundation embarked on this project which promotes the purchase of green gold or jewellery which isn't created by putting labourers through hardships.

• WHAT IS THE ANTARCTICA TREATY?

The Antarctica Treaty, signed in 1959, was a path-breaking agreement among countries of the world. There are certain regions located beyond the sovereign jurisdiction of any country of the world. Therefore, they require common governance by the international community These are known as 'res communis humanitatis' or Global Commons. It includes not only Antarctica but also the ocean floor and outer space. According to the treaty, Antarctica's environment and ecosystem will be protected. Since 1959, activities in the area have been limited to scientific research and development, fishing and tourism. Even these limited activities have not prevented this region from being degraded by waste, for example, oil spills. The expansion of the treaty was Antarctic Environmental Protocol of 1991.

• WHAT IS A PAGODA?

A pagoda, in South-east Asia, is a cone-shaped monumental structure built in memory of the Buddha. But in the Far East, a pagoda is a tower-like, multi-storeyed structure of stone, brick, or wood, usually associated with a Buddhist temple complex. The pagoda is derived from the stupa of ancient India, which was a dome-shaped commemorative monument, usually erected over the remains or relics of a holy man or king.

• WHY DOES FEBRUARY HAVE 28 DAYS, AND JULY AND AUGUST, 31 DAYS?

According to a popular legend, July was named after Julius Caesar and hence it had 31 days. Later, when Augustus Caesar took over the Roman Empire, he wanted August, the month named after him, to have 31 days as well. Hence, the two extra days were taken from February, which was then left with 28 days. However, some historians d.on't agree with this reasoning. They believe February always had 28 days ever since the time of King Numa Pompilius. He decided that a year would have 355 days, the length of 12 lunar cycles. Back then, even numbers were considered unlucky So, he created seven months with 29 days, and four with 31. Since he now needed one short even-numbered month, he chose February, as it was considered the least favourite month for it arrived during the middle of winter. And hence, it was given only 28 days.

• WHAT IS RICE WINE?

Rice wine is made from fermenting freshly steamed glutinous rice. Most rice wines are low in alcohol content, light in colour, noncarbonated and have a sweet flavour. Rice wine is categorized according to the degree to which rice is polished. It does not usually improve with age and should be preferably consumed within one year of bottling.

• WHY WAS THE NEW AMSTERDAM COLONY ESTABLISHED?

New Amsterdam was established by Dutch colonisers in 1624 in what is known today as New York city The town of New Amsterdam became a city in 1653 when it received municipal rights and was reincorporated as New York city in June 1665. The town was founded on the southern tip of Manhattan island as the most optimal place for permanent settlement by the Dutch West India Company and was strategically located on the south of the Hudson river. The location was best suited to defend the integrity of the New Netherlands province and was entrusted to safeguard the West India Company's exclusive access to New Netherlands' other two estuaries — the Delaware river and Connecticut river.

• WHICH WAS THE FIRST WAR FOUGHT IN THE HISTORY OF MANKIND?

If we define war as a large-scale violent conflict between two states employing the military, the earliest recorded wars might have taken place between various city states in the Mesopotamian region during the period 3,000-2,300 BC in the Bronze Age. The first recorded evidence of such a war was the one between the two city states Lagash and Umma, estimated to have taken place in 2525 BC. From the stone slabs bearing inscriptions related to the war, it could be inferred that the war employed professional soldiers wearing helmets who moved on chariots. The weapons employed were maces and swords.

• WHERE DOES SANTA CLAUS LIVE?

The original Santa Claus lived nowhere near the North Pole. If the 4th century bishop known as Saint Nicholas of Myra — the inspiration for Santa Claus — existed at all, he lived in Lycia, a province of the Byzantine Anatolia, now in Turkey Santa Claus is a corruption of the Dutch name Sinte Klaas for St Nicholas, the patron saint of children and unmarried girls. Tradition says he gave bags of gold to three daughters from a noble, but poor family as their dowries, thus saving them from a life of prostitution. As the legends developed in the Netherlands, the three bags of gold were replaced by a bulging sack of presents which Santa Claus distributed to children on December 6, St Nicholas' feast day Later, this custom caught on to other parts of the world, to give gifts to good people and punish the bad.

• WHAT IS THE SEEHECK EFFECT?

The principle of the thermocouple was first described by Seebeck in 1821. Seebeck discovered that when wires of two dissimilar metals were joined together to form a circuit of at least two junctions, a current would flow when the junctions were at different temperatures. This phenomenon, called the Seebeck Effect, is the basis upon which thermocouples are designed.

• WHAT IS FOUR-DIMENSIONAL CINEMA?

What we normally see today in theatres are two-dimensional movies with multi-channel sound. In three-dimensional movies, viewers are required to wear special glasses which create 3-D images of objects in the movie. Chhota Chetan and Shiva Ka Insaaf were such movies released two decades ago. Fourth dimension in a movie creates an overall different experience. In addition to the effects of 3-D features, viewers can experience the movies through other senses like sight, sound, odour, touch and also have personal remote control. Viewers are seated in special seats which have bass shockers and other special fittings which make them a part of the complete 4-D experience.

• WHAT IS BOW SHOCK?

In aerodynamics, bow shock is a normal shock that occurs in front of an object within a supersonic flow. Unlike an oblique shock, the bow shock is not attached to the tip, off the object in the flow. Oblique shock angles are limited in formation based on the corner angle and upstream Mach number. When these limitations are exceeded, a bow shock occurs instead of an oblique shock. Therefore, bow shocks are often seen forming around blunt objects. In astrophysics, bow shock is a boundary between a magnetosphere and an ambient medium. For stars, this is typically the boundary between their stellar wind and the interstellar medium. In a planetary magnetosphere, the bow shock is the boundary at which the solar wind abruptly drops because of its approach to the magnetopause.

• WHAT IS ASSUMPTION DAY?

Assumption Day is, according to the Roman Catholic church, the day on which the Blessed Virgin Mary was, along with her body and soul, accepted (or 'assumed') in heaven. It is usually celebrated on August 15 by Roman Catholics. In some parts of the world, Assumption Day is a public holiday; in some parts it is a day of solemnity and prayers, whereas in some other parts, it is a day of feasting and festivities. Although in the early days of Christianity some held that it was not certain how the Virgin Mary's life ended, from the 5th century AD onwards, Christians believed that the Virgin Mary did not actually suffer a physical death and that she passed into heaven with her physical body and soul on Assumption Day The above day was officially recognised through a Dogma by the Church only in 1950. The Assumption has also been a subject of Christian art for several centuries.

• WHAT IS HEIRLOOM GARDENING?

An heirloom plant, heirloom variety, or (especially in the UK) heirloom vegetable is an open-pollinated cultivar that was commonly grown during earlier periods in human history, but not used in modern large-scale agriculture. Since most popular heirloom plants are vegetables, the term heirloom vegetable is often used instead. The trend of growing heirloom plants in gardens has been growing in popularity in the United States and Europe over the last decade. This is called heirloom gardening. Some examples are heirloom tomato, forbidden rice and Bhutanese red rice.

• WHAT IS DIES IRAE?

Dies Irae literally means day of wrath. The mediaeval Christians were preoccupied with the end of the world; they anticipated the Last Judgement, followed by the millennium. After the fall of the Roman Empire in the West there was a revival of the belief in the end of time. The year 1000 likewise excited mythological speculation, as did famines, plagues, and earthquakes. Most influential were the views of the visionary Joachim of Fiore. He divided history into several ages and said that 1260 would be the fulfilment of the Age of the Spirit, which had begun with St Benedict. At that time, mankind could expect a new revelation, the coming of the anti-Christ, and the last days of wrath. This myth, written down at the behest of the Papacy, exerted a potent influence on mediaeval thought, and in its vision of a future world where the Holy Roman Empire and the Church of Rome would give place to a free community of perfected beings who have no need of clergy or sacraments or scripture, it anticipated modern millennial theories.

• HOW MANY COUNTRIES DOES THE DNIEPER FLOW THROUGH?

Russia, Belarus and Ukraine are the three countries through which Europe's third-longest river flows. It originates in the south-west of Moscow and flows through Smolensk (Russia), Mogilev (Belarus), Kiev (capital of Ukraine), Dnepropetrovsk and Kherson (Ukraine) and empties into the Black Sea.

• WHAT IS ANTHROPOCENE EPOCH?

The current geological epoch we live in is called Holocene, which began around 9600 BC. However, considering the way humans have altered the course of the Earth scientists suggest that the epoch be renamed anthropocene. Nobel-prize winning chemist Paul Crutzen coined this term in a casual remark in 2002, while talking about how the Earth was entering a new epoch due to increasing human population and economic activity However, other scientists want this word to refer to the human impact upon the planet.

• WHAT IS ANTI-DUMPING DUTY?

If any company exports a product at a price lower than what it normally charges in its home market, then it is dumping the product. Opinions differ as to whether or not this is unfair competition, but many countries take action against dumping by imposing anti-dumping duty Thus, anti-dumping duty is an extra import duty on a particular product from a particular country in order to bring its prices closer to the normal value of that product in the country it is imported to. It is done to protect its own industry from predatory pricing. The World Trade Organisation does not prohibit antidumping policies and allows any country to take anti-dumping action against the countries which violate the principles of General Agreement on Trade and Tariff.

• WHAT ARE POLAR COORDINATES?

It is a system of coordinates in Geometry whereby the position of a point, say P, in a plane can be determined with reference to a fixed point called origin, denoted by 0, and a predetermined direction represented by a ray OA. The measure of length OP, denoted by r, and the measure of the angle that OP makes with OA, generally denoted by a Greek letter theta, are called polar coordinates of P and, P is called the graph of r and theta. One pair of values of r and theta corresponds to only one point in the plane and one point in the plane corresponds to only one pair of the values of r and theta.

• WHAT'S THE ORIGIN OF THE TERM 'TOP DOG'?

'Top dog' means one who is dominant or victorious. When wooden planks were sawn by hand, two men did the job using a two-handed saw. The senior man took the top handle, standing on the wood, and the junior took the bottom, in the saw-pit below. The irons that were used to hold the wood were called dogs and that the bottom position was much more uncomfortable. The term 'top dog' originated from this practice.

• WHICH IS THE FIRST ART GALLERY?

The term art gallery refers to two different kinds of places: 1. A place which exhibits items of art (an art museum), and 2. A place which sells art items. The oldest art museum is supposed to be housed in the Cosquer Caves, the under-water caves, near Marseilles. The caves consist of finger tracings, impressions of painted hands, and painted and engraved figures of animals. The oldest works in these caves were estimated to have been created 29,000 years ago. Art galleries that exhibit and sell works of art on a large scale have been in existence since the 17th century AD. Most of the oldest art auction houses that exist today in Europe have been founded in the first half of the 18th century Viennabased auction house Dorothium, which claims to be the oldest art auction house of the world, was founded in 1707, and Sothebys, the oldest and largest art auction house of England, was founded in 1744.

Stearman Aircraft Aviation Interview

Boeing Aircraft Company

Boeing Beats, but Stock Falls

The Boeing Company (BA) overcame market pessimism, showing hardiness in its core businesses with second quarter fiscal 2010 earnings of $1.06 per share, outpacing the Zacks Consensus Estimate of $1.01. The company's results exhibit solid performance across its core businesses amid lower volumes.

However, the company, like its defense peer Lockheed Martin Corporation (LMT) fell short of year-ago earnings. Last year, Boeing reported earnings of $1.41 for the corresponding period.

The street was anxious of Boeing's ability to recover since its commercial airplane deliveries were badly affected by cancellation and deferment from customers absorbing the after-shocks of the worldwide recession. As a result, Boeing's quarterly revenue declined 9.2% year-over-year to $15.6 billion, lower than the Zacks Consensus Estimate of $16.4 billion.

Segmental Results

Commercial Airplane

Boeing's Commercial Airplane segment in the reported quarter saw a stark 9% drop in deliveries to 114 units. A lower number of 737 and 777 airplanes flew out of Boeing without a single 747 during the quarter.

As a result, Boeing's quarter revenue has dropped 12% to $7.4 billion. The segmental operating margin contracted to 9.2% from 9.7% in the year-ago quarter due to lower new airplane deliveries.

Boeing Defense, Space & Security

Boeing Defense, Space & Security segment witnessed an 8% drop in its quarterly revenue to $8 billion. This was due to lower volume in Network & Space Systems, in part offset by a favorable aircraft delivery mix. Boeing Military Aircraft (BMA) quarterly revenue rose 4% to $3.6 billion driven by higher Chinook deliveries and volume.

Network & Space Systems' revenue declined 24% to $2.4 billion, impacted by lower volume on the Brigade Combat Team Modernization and Ground-based Midcourse Defense (GMD) programs. Global Services & Support (GS&S) revenue fell 3% to $2 billion on lower maintenance modifications and upgrades volume.

Overall segmental operating margin contracted to 8.9% from 10.1% in the year-ago quarter due to lower margins in military aircraft and services.

Boeing Capital Corporation

Boeing Capital Corporation (BCC) reported quarterly revenues of $162 million compared to $167 million in the year-ago quarter. The segment generated earnings of $55 million compared to $36 million in the year-ago period. During the quarter, BCC's portfolio balance declined to $5.3 billion, down from $5.7 billion at year end, on normal run-off, asset pre-payments and depreciation.

Financial Condition

Boeing ended the quarter with cash and cash equivalents of $4.5 billion and short term investments of $5.6 billion. At year-end fiscal 2009, the company had $9.2 billion in cash and cash equivalents and $2 billion of short term investments. The company used $19 million of cash in operating activities in the first half of 2010, compared to $1.2 billion generated in the year-ago period. Long-term debt droppedd to $11.4 billion at the end of the quarter from $12.2 billion at the end of fiscal 2009.

Outlook

Boeing reaffirmed its fiscal 2010 revenue in the guidance range of $64 billion – $66 billion and EPS in the range of $3.50 – $3.80. The guidance range is based upon secure operating performance accompanied by lower volumes, higher pension expense and investment in development programs.

Commercial Airplane segment's 2010 delivery guidance range remains unchanged at 460 – 465 airplanes. Segmental 2010 revenue guidance range is reaffirmed at $31 billion – $32 billion. However, operating margin guidance range has been raised to 7.5% – 8.5%, up from 6.5% – 7.5% on expected effective operating performance.

Defense, Space & Security segment's revenue guidance range for 2010 is reaffirmed at $32 billion – $33 billion. However, the operating margin guidance was reduced to approximately 9.5%, from approximately 10%, reflecting soft performance to date and the current contracting environment.

We are currently Neutral on the Zacks #3 Rank stock.

Navy Vought

The Navy F4U Corsair saw service in both World War II and the Korean War as a carrier-flown fighter plane, most notably in the Marianas and at Okinawa. It was one of the most famous planes to be developed during the war, and production lasted until 1952.

Prototypes of the plane were built in 1938 and 1939, and the production contract was awarded to Vought in June of 1941. The first carrier trials began on the USS Sangamon in late 1942. The design of the plane presented many challenges due to its high speed and the availability of new technology. Because of these problems, and because the simpler F6F Hellcat had already begun production, Corsairs did not find their way aboard U.S. aircraft carriers until 1944.

The F4U Corsair was designed to be the fastest fighter plane ever built. Using the largest engine available, the 2,000 horsepower 18-cylnder Pratt & Whitney engine helped the Navy F4U Corsair become the first U.S. fighter plane to fly faster than 400 miles per hour.

The F4U was a single-engine fighter plane with a range of 1,000 miles. It featured a relatively large three-blade propeller measuring over 13 feet in diameter, and was the first U.S. Navy plane to feature fully retractable landing gear. Measuring 33 feet 4 inches long and with a wingspan of 41 feet, the Navy F4U Corsair weighed 14,000 pounds when loaded. The Corsair's most unique feature was its "bent" wing, the result of a powerful engine and large propeller. The wing design lowered the overall height of the plane, gave the pilot improved visibility, and reduced drag.

The production F4U Corsair featured 6 wing-mounted.50 cal Browning heavy machine guns. Despite its new technology, the Corsair was also the last American fighter plane to use fabric skin on the top and bottom of each wing as well as for the ailerons, elevators, and rudder.

Despite its impressive performance, early Navy pilots to use the Corsair often termed it the "hog," "hosenose", or "bent wing widow-maker" due to the poor visibility over its long nose. However, opinions turned favorable after kamikaze attacks prompted more Corsairs to be moved to aircraft carriers. Known as one of the most formidable American fighter planes of its era, the U.S. Navy racked up an 11:1 kill ratio with the F4U Corsair. The F4U compared especially favorably to most Japanese aircraft, with a 12:1 kill ratio against Japanese planes. The Corsair dropped over 15,000 tons of bombs during the war, or 70 percent of the total bombs dropped by fighters. Although designated as a carrier fighter, more Corsairs were flown from land-based runways. By the end of the war, Corsairs could be found on Okinawa, in the Philippines, and elsewhere.

During the Korean War, the Navy F4U Corsair began to be replaced by the AU-1 Corsair and other models. Over 12,500 F4U Corsairs were manufactured by Vought overall, in 16 different variants. Over two dozen U.S. Navy F4U Corsairs are believed to be still airworthy, and restored planes can be found in museums and other locations, mainly in the United States.

Classic Pedal Cars specializes in premium quality pedal planes. The Authentic Navy F4U Corsair Pedal Plane is one of our favorites!

I have asked what is the top 10 best aircraft, give me the top(bottom) 10 aircraft, be inventive!?

This may be subjective, as the Airforce, Navy and Marines may have some very "different" ideas as to the WORST aircraft; tested, flown, in service,
Here is my number one aircraft
1.Vought F7U Cutlas, the "Gutless Cutlas". go from there..

Breda 88, Italian attacker-heavy fighter, when the prototype took off, it performed very good speed, agility....but when they armed(machine guns, ammunitions, and some bombs) it was hardly able to take off...

Baulton Paul Defiant, British fighter, was probably the most useless fighter of the WW2 because of the armament in turret. After few succesful missions because german pilot confused it for spitfires or hurricane and attacked it from behind, but then they started attacking it from the bottom. This fighters were soon retired from the first line.

these are the only that came into my mind at the moment...

In my experience, one of the most tedious aspects of travel is finding ways to pass the time on long flights. My solution? Simple, sleep your way through the boredom! Here are some of my favorite tricks to catch some zzz's at cruising altitude.

1) Bring your own pillow! This is probably the most important thing in my opinion. Your own pillow will not only be much more comfortable than the tiny airline pillows (that usually feel like they're stuffed with straw) but it can also give you that familiar feeling (and scent) of sleep that you are used to. This calming effect can help to offset some of the stress and anxiety you may feel when traveling and help you relax a little more.

The main thing to remember when bringing your own pillow is to make sure it's not too big to carry on-board with you.

2) Bring a portable music device with you. It can help a lot if you bring your Zune, iPod, or other personal music device along on your trip. Be sure to have some soothing tunes loaded up before you go and use them to drown out the oft-annoying ambient sounds associated with modern travel. While this won't block out the roar of twin-turbine jet engines firing up at takeoff, it can help you ignore that screaming three-year-old 12 rows back. A huge upgrade to this technique is to use noise-canceling headphones if you can. They're pricey, but if you travel a lot you will be glad you splurged on them.

3) Avoid the airport Starbucks before your flight! This is kinda obvious but still overlooked by lots of us. That Triple Grande Choco-Mocca with Vanilla Shot might sound really tempting but the resulting caffeine overdose (coupled with the frequent visits to the airplane restroom) will make it difficult to get your in-flight beauty rest. Fight the coffee urge until you reach your destination.

Hopefully these simple tips will help you in your quest for quiet solitude at 35,000 feet. Relying on familiar comforts and avoiding slumber-impeding substances can accomplish more than you might think. Here's to you sleeping through many flights to come!

Where's the quietest place on an air plane in Economy class?

My family and I were choosing seats on the airplane and we were thinking of sitting in row 30 and 31, which is right beside the left wing on the Airbus 343.
My mom said it would be noisy, and she suggests sitting at the very back of the plane...

So, other than sitting in First and Business classes, where would be the quietest location on an air plane in Economy class?

I'm not sure where the quietest place is, there probably isn't one. But, it's safest to sit near the wings. Also, seats near the emergency exit are more comfortable because there is a lot more leg room.

Bleriot Airplane

First Flight Across the English Channel with the Bleriot XI Monoplane

              Great Britain, always disconnected from the European continent because of its insularity, had only been reachable by sea until 1785, at which time the first balloon had successfully crossed the English Channel by air.  By 1908, 35 other aerial balloon crossings had been completed, but none had been made with heavier-than-air craft.  That had been about to change, and the feat would fully equal the many epic, record-breaking flights now firmly impressed in the annals of aviation history, such as the transcontinental flight made by Calbraith Rogers in 1911 with the Vin Fiz Flyer and the solo transatlantic crossing by Charles Lindbergh in 1927 with the Ryan Monoplane nicknamed Spirit of St. Louis.

               Sparked by the London Daily Mail’s 500 British pound challenge issued on October 5, 1908, an amount later doubled, the event had sought “the person who shall succeed in flying across the English Channel from a point on English soil to a point on French soil, or vice-versa” in a heavier-than-air craft without stopping.

               Although Wilbur and Orville Wright had been perceived as the only two capable of the feat, their involvement with aircraft sales-pursuing demonstrations had precluded their participation, despite a significantly increased prize offer, and Hubert Latham, who had spent two years in the French Army and had already successfully crossed the Channel in an aerial balloon, had been the first to accept the challenge.  Having already earned a French duration record and a world record for monoplanes for the one-hour, seven-minute, 37-second flight in his Antoinette IV on June 5, 1909, he had intended to make the crossing with this aircraft, taking off from cliffs at Sangatte, a village six miles from Calais, where he had set up a rudimentary camp.  French destroyers and crane-equipped tugboats would follow his course.

                Count Charles de Lambert, a second contender and Wilbur Wright’s first student pilot in France, intended to make the journey with Wright aircraft, but of his two machines, one had been damaged during a test flight and the other had not been readied in time for the event.

                Latham had suffered a similar fate.  Fighting strong winds during a July 13 crossing attempt, he had been forced to land in a corn patch, severing the right strut and wheel of his aircraft, while a second attempt, six days later, had resulted in an engine failure-caused water landing near the French destroyer following him.  The airplane, now too damaged for anything but a lengthy rebuild, had to be substituted by the Antoinette VII, although at least a week had been needed to prepare it for flight.

                It had been at this time that a third contender, Louis Bleriot, had entered the race with his own design, the Bleriot XI, a smaller, though not dissimilar aircraft to the Antoinette.  Incorporating several features already introduced by his earlier aircraft and therefore representing the latest in a series of evolutions, it had sported a primarily open, box-frame fuselage; a small engine; fabric-covered, pylon-supported wings; wing-warping mechanisms; an open cockpit; the cloche method of actuating both the wing-warping and the elevators; and a tri-wheel undercarriage.

                The rounded-tip wings, with an 8.53-meter span, a 1.83-meter chord, a 4.65 aspect ratio, and a 13.95-square-meter area, had been attached to the poplar fuselage, their trailing edges differentially warped to induce in-flight banking.  The 25-hp, three-cylinder, V-shaped, air-cooled Anzani engine, replacing the original seven-cylinder REP semi-radial, sported a 2.08-meter wooden propeller which produced 105 kilos of thrust at 1,450 revolutions-per-minute.

                The horizontal tail, comprised of a fixed, center section with elevating tips, had been built round a steel tube bolted to the fuselage underside by cast aluminum fittings, while the rudder, positioned 13 inches behind it, extended above the fuselage.

                The undercarriage had been comprised of two main, fixed wheels which swung on links to cater to cross-wind ground conditions and absorbed landing impacts by means of elastic springs, and a single, castering tail wheel.

                First flying on January 23, 1909 at Issy, France, and covering a 200-meter distance, the Bleriot XI, with its characteristic forward bedstead frame built up of two ash horizontal beams, two vertical beams, and two vertical tubes to provide engine and landing gear mounts, took to the air for a second time the following month on February 18, with a two-square-meter larger wing.

                Louis Bleriot himself had set up his camp on a farm at Les Barraques so that he could use its flat pasture as a runway.

                On July 23, de Lambert became the third pilot to officially enter the race, but of the three, he had been impeded by his still-unprepared aircraft while the other two had been hindered by the weather.

                Diminishing winds and clearing skies on July 25, however, indicated cross-Channel flight potential, and Bleriot, having already awakened early, warmed his engine by 0400, before making a 15-minute practice circuit and relanding.

                As the sun triumphed over night 35 minutes later, Bleriot prepared himself to triumph over flight, climbing into the fabric-covered monoplane and throwing to the ground the crutches he had used to help him walk after a prior flight fuel tank explosion had burned his left foot.  “If I cannot walk, I will show the world I can fly!” he had proclaimed.

                The sun inched above Calais Castle.

                After oil had been added to the aircraft’s 25-hp engine and its 17-liter fuel tank had been topped off, Anzani, maker of the powerplant which bore his name, turned the wooden propeller and the five men holding the tail down released it when Bleriot had commanded, “Let’s go!”

                Throttling into 1,200 revolutions-per-minute of power, Bleriot accelerated his airplane over the grass toward the sand and the open Channel, gateway to England and aeronautical history, pulling back on the cloche and separating its two still-spinning, bicycle-like wheels from French soil, as if they continued to ride some invisible, aerial track.

                Surmounting the telegraph wires, the aircraft climbed to 180 feet, inching out over the water body which had generated the challenge.  Reducing power, it leveled off at 260 feet and maintained a 43-mph airspeed.

                The French destroyer, Escopette, intended to provide flight following and carrying journalists and Bleriot’s wife, moved into view.  Seeing the propeller-pulled object in the sky amid the cylindrical sun’s ascent above the horizon, she yelled, “Mon Dieu!  There he is!”  as her husband gracefully passed overhead on fabric wings which had created a 260-foot-high aerial bridge between landmasses, creating the lift for which they had been designed.  But the speed, one-and-a-half times greater than that of the ship’s lumbering 26, had rendered it a far superior opponent and it quickly overtook it.

                Attempting to make a wide circle in order to remain in sight, Bleriot quickly realized that his aircraft had been demonstrating its intrinsic speed and distance advantage over the water-plying vessel.  Its intended directional aid toward England, alas, could not be used.

                Relaxing his grip on the cloche, Bleriot permitted the aircraft he himself had designed to find its own way across the water.

                Completely disconnected from soil and soul after ten minutes aloft, with neither coast ahead nor coast behind visible, he felt “alone, unguided, without compass, in the air over the middle of the Channel.”

                The wind had begun to regain its strength.  The 25-hp Anzani engine, apparently overheating from its continuous-power output, suddenly sputtered and the airplane nudged itself out of its artificial plateau toward the Channel’s waves and whitecaps.  Boring through a rainsquall, whose pelting douse of cool water ironically nourished the powerplant of its needs, the aircraft regained even, altitude-holdng power.

                Wrestling with wind and fog, it fought its way to England.  A long gray line, rising above the horizon and representing its destination, appeared ahead, but it did not resemble Dover.  The southwest wind had diverted the frail bird to St. Margaret’s Bay instead, yet the Dover Lighthouse, rising prominently in the west, had marked the location of the castle, and Bleriot banked left toward it, penetrating strong headwinds and paralleling the coast at a one-mile distance. 

                Following the presumably harbor-approaching channel boats, Bleriot spotted reporter Charles Fontaine waiving the promised French tricolor to mark the entrance over Shakespeare Cliff of North Foreland Meadow, itself next to Dover Castle.

                Completing a half-circle above the Channel, Bleriot initiated his approach to England—and history.  Threading its way between the gap and passing over land for the first time in more than half an hour, the aircraft banked to avoid red buildings on its right, but it had been clenched by the fist of low-level turbulence and winds, which had thrice spun it round, rendering it uncontrollable.  "At once, I stop my motor,” Bleriot had later stated, “and instantly my machine falls straight upon the land from a height of 65 feet.  In two or three seconds, I am safe upon your shore,” although the airplane’s propeller and landing gear had sustained damage.

                Latham, still asleep on the continent which Bleriot had just bridged, did not fly at all that day and had to accept defeat.  Although he had made the attempt two days later, he had once again plunged into the Channel when his engine had failed and he had sustained injuries.

                Because of the historical event, the Bleriot XI, which had been offered in training, sport, military, and racing versions with varying dimensions, wingspans, engines, horsepower ratings, and capacities, had attracted over 800 worldwide sales, having been the most massively produced pre-war monoplane.

                Although the relatively short, 23-mile distance between Les Barraques in France and North Foreland Meadow in England had been covered in 36½ minutes, the flight’s effects had been disproportionally long.  For England, geographically protected and isolated by its surrounding Channel, its insularity had ended.  For France, it had bred the designer, aircraft, and pilot which had triumphed over that Channel.  And for the world, it had meant that the airplane, increasingly able to connect countries and continents, had paved the way toward unlimited future civil and military application.

What is the Worlds oldest flying airplane?

I just saw the 1909 Bleriot in Rhinebeck that's the oldest in the US but I want to know what is the oldest still flying. Not the oldest airplane, that would be the Wright Flyer.

The oldest in the world is another 1909 Bleriot, this one in England. It's only three weeks older than Old Rhinebeck's.
