Indian Instruments

A task to research up to eight Indian musical instruments including sitar and tabla.Sitar
The Sitar is one of the most famous Indian musical instruments. Despite the physical resemblance and similar sounding name, it is not technically related to the guitar, but to the lute family. A typical Sitar will have nineteen strings, of which four will be drone strings, four will be playing strings and eleven will be sympathetic or resonating strings. Players pluck these strings with a mizrab (a plectrum made of wire).
Tabla
The word Tabla refers to a pair of drums. The right-hand drum (dayan) is small and wooden, the left-hand drum (bayan) is normally made of brass, coated with chrome or nickel. The skin of each drum has a large black spot in the centre. These spots, composed of iron filings, soot and gum, create a timbre which is similar to that of a bell.
Shehnai
This is the Indian version of an Oboe, with four reeds (two upper, two lower) and eight holes which are sometimes plugged with wax. The Shenhai is made primarily of wood but the bell is composed of brass. The Shehnai is often used in temples because of its distinctive sound, and often appears at North Indian weddings.
Tambura (also known as Tanpura)
The Tambura is a drone instrument known for its rich sound. There are three different types of Tambura: Marij, Tamburi and Tanjore. The Marij style is 3-5 feet long with a rounded resonator chamber and a straight hollow neck. At 2-3 feet long the Tamburi style is the smallest. This has made them increasingly popular in recent years due to their portability. The Tamburi style has five strings and is tuned to a higher octave. They are often used by solo artists. The Tanjore style is again 3-5 feet long and features a spherical lower chamber made of solid wood.
Bansuri
The Bansuri is a very old instrument which for thousands of years has been used by shepherds and folk musicians. These Indian flutes are carved out of reeds and bamboo, with six or seven holes along the shaft. The Bansuri is a very simple instrument to play and requires little tuning beforehand. In large groups of players the Bansuri is normally used as a Soprano instrument. Their tunes are also commonly found in film music.
Santoor/Santur
The Santoor’s strings vary in number. The number can range from twenty-four to one hundred. The Santoor is played by striking the strings with a light wooden mallet, producing a vibrant sound. The name Santoor is derived from a Persian word meaning a hundred strings.

Antoine Lavoisier
The life of the French scientist, including how he discovered Oxygen.
Antoine was born Antoine-Laurent Lavoisier on the 26th of August 1743 to a wealthy upper-class French family. Antoine gained a degree in law from the Collège Mazarin, but his true interests were in Science and Mathematics. He began to pursue these interests from the age of 21, by studying geology, astronomy and botany. In 1786 he was accepted into the Academy of Sciences after a winning essay on the best means of lighting a large city at night.
He was married in 1771, to Marie-Anne Pierette Paulze (who was 13 years old at the time). Far from holding back Antoine’s career, Paulze learned English so that she could translate the works of earlier scientists. She also drew many of the sketches of Antoine’s lab and equipment, as well as those which were featured in his book, Traité Élémentaire de Chimie (Elementary Treatise of Chemistry).
Up until Lavoisier’s work, many scientists still believed in an invisible substance called Phlogiston. The theory behind phlogiston was that in all combustion of materials, phlogiston was released. All flammable substances were said to contain phlogiston. Scientists of the ancient world developed this theory when they realized that wood ash and iron rust (both known as “calx”) were lighter than the original substances. At the time people believed that materials were composed of both calx and phlogiston, and that weight was reduced when phlogiston was released during combustion. It was also theorized that when a material in an air-tight container stopped burning, it was because the air around it had become saturated with phlogiston (this was called “phlogisticated air”) and could no longer support combustion.
Lavoisier came up with a different theory; he said that the mass of a mixture remained the same throughout chemical reactions. He also believed that, during combustion, materials did not release phlogiston, but took in another gas. In effect, Antoine’s gas was the polar opposite of phlogiston. Antoine called his new gas “oxygen”. He attempted to prove his ideas in 1777, by heating a bell-jar of air and mercury for 288 hours. After the mercury “calx” had formed, Lavoisier measured the volume of air inside the jar and found that it had decreased by 16%, and that all of the remaining gas was what we now call Nitrogen. This proved that oxygen had been used up in forming the calx and that no phlogiston had been released. Four years later, Lavoisier further proved his theories by splitting water into oxygen and hydrogen, then recombining them to form the same volume of water. When he published Traité Élémentaire de Chimie, Antoine named thirty-three different chemical elements as well as explaining his oxygen theory.
Eventually, people accepted Lavoisier’s ideas and phlogistonists gave up their arguments.
Although Antoine Lavoisier became a success, he was eventually consigned to a cruel death: earlier in his life, he had invested in the Ferme Générale, a company which collected tax on imported goods. Lavoisier did not abuse his power, but many others did, and during the French Revolution, all members of the Ferme Générale were imprisoned. On the 8th of May 1794, fifty-one year-old Antoine-Laurent Lavoisier was placed on a guillotine and decapitated.

Why the French Revolution Happened

An essay detailing the incompetence of the government and monarchy, the failure of the estates system, and the influence from America.The French Revolution was a major turning point in the history of France, this was the point at which France stopped being a medieval dictatorship and became a modern country. However, this was not something that happened in an instant, the roots of a revolution had been building up for a long time. In a changing world, France was becoming out-dated in terms of how the country was run: The hierarchy was corrupt, the monarchs were incompetent and the people were in poverty. These are not signs of a good country.
The reason for France being run in a bad way is that Louis XVI and Marie Antoinette were not very good at ruling. Louis did not particularly care about his job. He was far more interested in pursuing his hobbies than he was in controlling his country. Louis also suffered from a very poor figure and had limited visual capability. Marie-Antoinette, meanwhile, was rowdy and undisciplined, so was hard to educate. The result was that the “pair of nincompoops” were not respected by the people, nor aware of the problems which were arising beneath them. These were not the only problems: the French Parliament spent far more money than they received, so the debts grew and grew.
While the monarchy squandered money, the people of France had none. In the years leading up to the revolution, the cost of bread (which made up most of a French peasant’s diet) rose by 45%, whereas the wages received by the “Third Estate” did not reflect this, and only rose by 22%. This caused most of France to go hungry. One reason for the strangling of the cash flow was that members of the lowest had to pay inordinately large taxes to the government, but the money never reached its destination. Huge chunks of the tax funds were kept by greedy tax collectors, eager for the chance to make themselves wealthy. Between the debts of the government and the poverty of the poor, the French economy was twisting into a tight knot which would eventually tear it apart.
Another major result of France’s backward ruling was the fact that, even in the 1780s, the country was still following the medieval Estates system. The general idea was: Members of the church were rich, Nobles were rich, the monarchs were very rich and everybody else was effectively slaves. Thus, clergies and rich families lived in splendour while the peasants were worked to death and stripped of all wealth. This was the country which Louis XVI and Marie Antoinette saw. However, the reality was fast moving away from this because many Third Estate members were beginning to accumulate power and wealth, while the cash of the first two estates was dwindling. French social hierarchy was o longer as simple as the king and queen thought, and action should have been taken to adapt the system to suit the changes. But this did not happen. Instead, the ignorant Louis and Marie-Anne were practically oblivious to the changes which were happening, and took no action as a result. This meant that France was quickly transforming into something new, but the country was simply not ready for the change.
While France was falling apart, America was only just emerging as a country. In the 1770s, American colonists were fighting for their rights as an independent nation against the controlling arm of the British Empire. The French government was glad for a chance to take a shot at Britain, so soldiers were sent to assist the Americans in their struggle. The foundation of America’s fight for independence was the idea that no people should have to pay taxes without gaining the rights to participate in making the country’s rules. The French soldiers agreed with this, so much that they tried to make it work for their own country, by rebelling against “the Toffs”. Personally, I think that sending French soldiers to America was one of the worst ideas in the history of government. If the king and queen had been paying more attention, they would have foreseen the effects of this decision and put a stop to it. They should have taught their subjects that the Americans were anarchists and criminals. If siding with Britain was to be too risky then the French government should not have poked their noses in at all. Then they would have avoided wasting vast amounts of money in transforming their soldiers into revolutionaries.
Overall, I believe that the French Revolution was the result of some dreadful leadership by Louis and Marie-Antoinette, combined with a changing world. As a result, France did not gradually shift into the modern era, but was instead dragged along the ground by the might of a revolt, becoming smashed and mangled as a result.

Alfred Nobel
A factfile on the inventor of dynamite.
Alfred was born in Stockholm (Sweden) on October 21st 1883. Over his lifetime he lived in many different countries. This led him to consider himself a “world citizen”. Between 1850 and 1863 he travelled through Germany, France and America studying Chemical Engineering. In 1852, he and his father worked on developing nitro-glycerine for use commercially and in the Russian army. This was a highly dangerous and unstable substance, and he wanted to find a way of manufacturing it safely. In 1864 he dedicated his life to explosives, particularly nitro-glycerine. His experiments, however, proved deadly; on September 3rd 1864, an explosion at the Heleneborg factory killed five people (including Emil, Alfred’s younger brother).
In 1867, Alfred patented Dynamite, his new invention. He has discovered that mixing nitro-glycerine with “kieselgur” (soft sedimentary rock) made it considerably easier to use. He also found that dynamite could easily be shaped to fit drilling holes, which made his invention a vital part of nearly all construction work from then on. Having perfected the explosive, Alfred then created a “blasting cap” for the rods of dynamite, which allowed them to be detonated by lighting a fuse. Over the next few years, dynamite became a huge success. Alfred travelled around the world, founding factories and laboratories in over twenty different countries. Dynamite, however, was not his only creation; he also helped to develop synthetic versions of leather, rubber and silk. Over his lifetime he accumulated over three hundred patents.
On December 10th, 1896, Alfred Nobel passed away in San Remo, Italy. Prior to this he had written a will asking for his money to be spent on prizes for people who had performed exceedingly well in one of five different fields:
-
Chemistry
-
Physics
-
Literature
-
Peace
-
Physiology or Medicine
These prizes have been awarded nearly every year since 1901, and are considered the highest praise that any scientist could hope for.

The Roman Baths

A description of the public baths used in ancient Rome.Public baths were a common feature in many Roman towns and cities. They were used by men and women of all ages to wash, exercise and meet acquaintances.
A visit to the baths would begin with the palaestra. The palaestra was the main exercise area, in which people would take part in activities such as ball tossing, wrestling and fencing. This is where a person would first meet with their friends and colleagues. A short while later, they would pass through the apodytērium. Here they would strip naked and give their clothes to a slave, who would place them in a recess in the wall until later.
The next stage of the baths was the tepidārium. This was a large room where the walls were lined with benches. The room was kept at a mild temperature, allowing visitors to slowly warm up and prepare for the caldārium where they would bathe in a large hot bath and have slaves clean them with oil. For this, the visitors would lie down on the floor and slaves would massage the oil into their skin. Then the slaves would scrape the oil (and bodily dirt) off using various strigils. Strigils were blunt metal scrapers, each was designed to scrape a different part of the body. A long, flat scraper, for instance,would be used on the back, while a short, curved variety was needed for the arms and legs. After this, the slaves would give the visitor a massage, then they would proceed to the frigidārium to cool off in the cold plunge pool, then go back to the apodytērium to get dressed and go home.
The tepidārium and caldarium were heated by a system called the hypocaust: The floors of all the rooms were suspended on numerous stacks of bricks, fires would be lit outside, and the heat would be channeled into the spaces beneath, warming the room above it. Sometimes the walls would all be made hollow as well, allowing the heat to flow all the way around a room.

Non-Religious Years

Is it good or bad for the alternative system to be used? With reasons, plus an explanation of how B.C./A.D. dates first came into use.Personally, I think that it is good that there is an alternative way of saying B.C./A.D, using those terms automatically suggests that you believe that Jesus was born in 1 A.D, which would be problematic if you are not Christian. Referring to the post-ancient world times as “The Common Era” allows you to use dates from thousands of years ago without submitting to Christian beliefs. If I were, for instance, to use the terms B.C. and A.D. when discussing historical events with a group of Hindus, they would likely be offended. Whereas if I were to say “before Common Era”, their feelings would remain intact.
There are other advantages, too. At present, there is great dispute over whether or not the position of the B.C. /A.D. borderline actually relates to the time when Christ was supposedly born. Most of us place the birth at what we now call 1 A.D., but actually it may have occurred as much as ten years before or after that. Obviously, B.C.E. /C.E are based on the Christian year numbering system, but at least it isn’t directly tied to the date on which Mary gave birth. This means that it won’t potentially need adjusting if the evidence that the current religious system is wrong becomes overwhelming. Also, in time Christianity will wither, die and be forgotten like many other religions before it, and the B.C./A.D. dates will become meaningless. At that point, the world will most likely switch to B.C.E. /C.E. dates instead.
Note: The term Anno Domini was invented in 525 C.E. by Dionysius Exigus as a way of dating Easter It was used by Anglo Saxons by 731 C.E., and had become widespread by the 9th century.

Why did the English Civil War begin?

An essay detailing King Charles’ fallouts with Parliament, and the rivalries between various religious factions which lead to violence.In 1642, war broke out in England; a battle was fought between King Charles I’s Cavaliers and Parliaments Roundheads. Each side was, in effect, fighting for the rights to the country. Why though, had the war begun? What had caused such an outbreak of violence? How had the kingdom come to war?
One of the main factors in the war was the fight for power between Charles and Parliament. The king did not want Parliament taking control of the country from him, and relations were turbulent. In 1625, Charles annoyed parliament by marrying Henrietta Maria, a French Catholic. They then annoyed him by only letting him raise customs duties for one year. He struck back by collecting the duties anyway, and dismissed Parliament for eleven years. Eventually, he was forced to recall them. Charles then tried to arrest five MPs, so Parliament seized his army. For seventeen years, there had been a constant tug of war between King Charles and his MPs. For nearly two decades they were at each other’s throats. It’s amazing that war didn’t break out sooner.
Most of the struggles between Charles and Parliament were centred on money. When Charles first acquired the throne, he was faced with debt left to him by his predecessor, and when he got England involved in wars with Austria and France, the king nearly went bankrupt. With no money, Charles had no power. What most previous Kings did in situation like this was raise taxes for several years until their pots were full again (then keep them up just for the sake of it). But Charles had the problem of Parliament, whom wouldn’t let him have any money. It was the pennilessness of Charles which forced him into the endless tug of war with Parliament. He would beg them for more and more money. Then, when his pockets were full again, he would send them away. But no matter what he tried, the king was being drained of his money.
As if his problems with parliament weren’t bad enough, Charles also had to contend with long running religious disputes between the Catholics and Protestants. At the time, Charles ruled over England and Wales (both Protestant). But he was also trying to control Scotland (Presbyterian and Puritan) and Ireland (strong Catholic territory). In order to simultaneously rule over all four countries, Charles would have to sort out the religious system. He tried, in 1637, to introduce The New English Prayer Book to Scottish churches. The Scots saw this as the start of an attempt to turn them Catholic and rebelled against the King. Over the next three years, his majesty twice tried, and failed, to defeat the rebels with his own army. Also, the Irish, tired of being bullied, attacked, and robbed by foreign Protestants, staged their own rebellion. Charles I’s empire was starting to become unstable, and was tearing apart on all sides.
Overall, I think that the English Civil War started because Charles was trying to control several different countries which were – due to religious differences- largely incompatible. It was inevitable that the people of the different nationalities would reject each other. Also, with no money and his powers being strangled by Parliament, Charles was not able to move to prevent it. However, I think that the New English Prayer Book was probably the final catalyst.

Who was to Blame for the English Civil War?

A table of who blamed whom, with a conclusion.Speaker Target of Blame Assertions The Pope The Puritans William Laud was right, though many others disagree: The puritans are too strict and cannot accept change. By refusing Charles and Laud to have any power over the church they are causing a major conflict and forcing people to take sides. The Irish The Protestants The Irish land was being stolen by foreign Protestants. The Irish Catholics were driven out of their homes. They rebelled in order to get their property back. Catholics were blamed for the war, and were allegedly spying for the Pope. The Scots Charles and the Bishops The Scots do not want Charles or Laud interfering with their religious practices. They have tried to force the Scots to us a Catholic-style prayer book and answer to bishops and priests. The Scots do not want to become Catholic. The Puritans Charles and Laud The King and his bishops have no respect for their subjects. They are abusing their power and changing the laws to suit them. Puritans are decent people who want simple church services. Charlies Everyone Else He was placed on his throne by God, his word is law and his people have no right to defy him. The King is Defender of the Faith and has the right to raise an army to defend his kingdom. He does what he thinks necessary, and no-one else’s opinion matters. My Conclusion
The English Civil War, as with most religious wars, is another case of Catholics blaming Protestants, Protestants blaming Catholics, peasants blaming king, king blaming peasants. Everyone blames each other for a long war over who has the right to the church. Even though both sides are Christian, they still manage to find a reason for killing each other. Then we have King Charles, who believes that he is God’s true emissary and that everyone should worship him – and makes all his decisions based on that judgement. History tells us that it is never a good idea to have two main religious groups under the rule of a greedy king. However I think that Charles was probably the biggest catalyst in the war: By meddling with the Church of England’s affairs, Charles made the Protestants angry. They then took their anger out on the Catholics, who fought back, causing war. If only Charles hadn’t been so pushy, arrogant and full of himself, he might have been able to maintain peace between the two faiths. From what I have seen, heard and read, Kings and Queens have a habit of getting into huge arguments with either the Pope or their Bishops. There have been many wars caused by political fallouts, or money, or powerful villains wanting to rule the world, but a staggering number of battles, wars, rebellions and terrorist actions have been caused by the inability of two different religions to get along with each other. Since history began, millions of people have died fighting over what they believe to be the one true faith. With that in mind, I’d say the person who really caused the Civil War was God.

Salmonella Typhimura


Where it was found, what the symptoms are, how long they take to appear, who is most at risk, and how to prevent infection.
Salmonella Typhimura, first discovered by American scientist Dr. Daniel E Salmon and his research assistant Theobald Smith in 1885, are a type of bacteria commonly found in human and animal intestines. Though the bacteria may sometimes go unnoticed, they can be passed out through an animal’s faecal matter, and ingestion of contaminated meat can lead to serious infections. Salmonella Typhimura, along with another strand named Salmonella Enteritidis, are believed to account for half of all human infections in the US.
Between 12 and 72 hours of the Salmonella Typhimurium entering the body, victims may begin to experience nausea, abdominal cramps vomiting and diarrhoea. These symptoms normally last for between four and seven days and can be treated with antibiotics, but for small children, the elderly and those with weaker than average immune systems, Salmonella poses a much more serious threat: if not treated properly, the infection can prove fatal.
Salmonella infections can be prevented by regularly washing hands with hot soapy water when preparing food, properly refrigerating meat before use and then cooking it thoroughly to kill any bacteria present. Keeping cooked and uncooked food separate helps to avoid cross-contamination.
