A virus is the smaller organism that produces disease. It cannot be seen directly by the ordinary microscope. But this doesn’t mean that science hasn’t been able to study the structure of a virus. Today there are ultramicroscopic that enable these tiny organisms to become visible. And science is able to know quite a bit about the sizes and shapes of various types of viruses by means of the electron microscope.
The electron microscope uses beams of electrons instead of rays of light. The electrons pass through the specimen being observed and strike a photographic plate on which a picture is obtained. In this way, it is possible to magnify an object about 100,000 times.
By using the electron microscope, it has been shown that viruses range size from about 300 mill microns to 10 mill microns. What is a mill micron? It is one thousandth of a micron. And a micron is about 0.00004 millimeters.

Hi dude! Hope you all doing good and I am very cheerful to see you all again here. And, at the moment I am going to share you all my acquaintance about Fossils. The best way we have knowing what creatures were alive on this earth millions of years ago are form studying fossils. Fossils are animal and plant remains buried in the rocks. These remains, which have in most cases petrified, may be of shells, insects, leaves, bones, whole skeletons, or simply the tracks made by ancient animals on the shores of swaps.
From such evidence, a scientist says that dinosaurs lived in the earth about 180,000,000 years ago, and that they pass out about 60,000,000 years ago. The fossils have been found that make these scientists believe this? - The mainly general ones are bones, teeth, and claws. From these, dinosaur’s skeletons can be reconstructed so we can’t estimate that how the body was built. May be, there have been trails and foot prints.

Hi pals. Have you ever seen a salamander? They are not very pleasant looking creatures. Their slender bodies, long tails, and sprawling legs make them look like lizards. And probably because they have a smooth, shiny skin that always looks wet, a legend has arisen about them that they can pass through fire without being harmed. But this isn’t true at all. Salamander’s natural home is in the water or in cool, moist places. When they are removed from this kind of environment, they die. Salamanders are an amphibian, which means they can live both in water and on land. Strictly speaking, the only true salamanders are found in Europe. But there are many creatures like the salamander in other parts of the world. Salamanders usually lay their eggs in water. The young have gills, like genuine water animals. When full-grown, the salamander usually develops lungs, loses its gills, and lives on land.

Hi dude! Hope you all doing good and I am very cheerful to see you all again here. And, at the moment I am going to share you all my acquaintance about Bees.In order for there to be a “queen bee” there must be a colony of bees. But not all bees live in colonies. There are species of bees called “solitary” bees. Among them there are only two kinds of bees, the males and the egg-laying females. But bees that live in colonies are called “social bees”, have a third form of bee known as “workers”. The workers are really female bees that ordinarily don’t lay eggs. So in a colony of social bees we have the workers, the males, who are called “drones”, and the one egg-laying female, the mother of the colony, who is called the queen. Here is how a queen bumblebee spends her life. She passes the winter in a hole dug in a sandbank or other suitable place.

Hi pals. Let I tell something about democracy. political democracy began early in history. In the Greek city states, especially Athens, there existed direct democracy. In Athens, however, the ruling class of citizens was only a small part of the population. Most of the people were slaves, and theses, together with women and foreigners, had no right to vote or hold office. So while a form of direct democracy did exist in ancient Athens, we would today find fault with many of its aspects. Political democracy has appeared in two general forms. A government in which all the people meet together to decide the policy and to elect the officials to carry it out is known as direct democracy. When the people elect representatives to carry out their wishes, the government is known as a representative with many people involved; almost all forms of democracy practiced today are the representative kind

Levi hutchins was a 26 years old clock maker in Concord, America. He was a dedicated person. He tried his best to punctual in everything he did. He wanted to reach his shop on time. For that it was necessary to get up early in the morning. It was his “firm rule” to awaken at 4 o’ clock in the morning. He tried to keep this habit in all seasons.
But sometimes he was in trouble. He failed to get up at the right time. When he failed to keep his punctuality, he became restless. In such cases, he appeared restless all through the day. It was at this situation, he wished to develop a device that could help him to get up at the right time.
The clockmaker began to think of a solution. He looked at his shelves of clocks and was inspired. He later wrote that the idea of a clock that could sound an alarm was difficult to be brought to the mind. Once the idea was accepted the making of it was much easier. He did not find it difficult to arrange for the bell to sound at the hour he wanted.
He constructed a pine cabinet. He transferred the mechanism of one of his large brass clocks into it. He also inserted a gear. The minute hand of the clock reached and touched the gear at 4 o’ clock. Then the movement of the gear set bellin motion the made some noise. That noise was loud enough to awaken him.
Hutchins died at the age of 94. He never thought of the mass-production of alarm clock. He wasn’t interested in money. He was just interested in not rising up at the right time no doubt, he achievement his ambition.

Hi dude. Now I like to share my view about the Australian Open. The Australian Open is one of the four Grand Slam tennis tournaments. It is held every year. The Australian Open is organized in the month of January at Melbourne Park. Thus, the Australian Open is the first Grand Slam tournament of a year. The tournament was held for the time in 1905. Like the other three Grand Slam events, it was contested by top-ranked amateur players. In the beginning, this tournament was known as the Australian Championships.
In 1926, the name was changed into Australian Championship. In 1968 it was called Australian Championships. In 1968, it was called Australian Open. The Australian Open is managed by tennis Australia, formerly the Lawn Tennis Association of Australia (LTAA), and was first played at the warehouseman’s cricket ground in St Kilda Road, Melbourne in 1905

Scientists were aware of this metal from 1787. But the problem was that they did not have a way to separate it. It was possible only in 1825. Hans Christian Oersted was the first to produce tiny amounts of aluminum. He was a Danish Chemist. Two years later, Friedrich Wohler found a different way to obtain the metal. He was a German chemist.
Wohler’s method was improved in 1854. It was Henri Deville who improved it. He was a French Chemist. Deville’s process was the turning point. It showed the way to the commercial production of aluminum. In the beginning, the price of aluminum was very high. Because it was extracted only in a very small quantity and it was a very difficult task.
In 1852 the price was around $1200 per kilogram. Due to the invention of Deville the price came down to around $40 per kilogram in 1859. Still, aluminum remained more expensive than many other metals. And as a result it could not be used for ordinary purposes.
Then on April 2, 1889, Charles Martin Hall found an inexpensive method for the production of aluminum. This invention brought the metal into common use.

Hi dude. Guru Dutt Sondhi was the representative of India in the International Olympic Committee. It was he who proposed the idea of holding the Asian Games. He put forward this idea during the 14th Olympic Games in London in 1948. The leaders of the Asian teams decided to form the Asian Athlete Federation. In February, 1949, the Asian athletic federation was formally formed and used the name Asian Games Federation.
It was decided to hold the first Asian Games in 1951 in New Delhi, the Capital of India. They added that the Asian Games would be regularly held once every four years. Later, a new association, Olympic Council of Asia (OCA) was created. OCA formally supervised the games from the 1986 Asian Games in South Korea. The latest development in the Asian Games is that cricket will be introduced in the next Games which are scheduled for 2010.

Hi friends. The Asian Games is also called the Asiad. Like Olympics, it is also a multi-sport event held every four years. Athletes from all over Asia take part in the Asian Games. The Asian Games is organized by the Olympic Council of Asia. The International Olympic Committee supervises this sports event. Medals are awarded in each event. With gold for first place, silver for second and bronze for third. The 15th Asian Games was held in Doha, Qatar from December 1 to December 15, 2006. The 16th Asian Games will be held in Guangzhou, China from November 12, 2010 to November 27, 2010.
The beginning of the Asian Games was with the Far Eastern Championship Games. Only three countries, Japan, Philippines and china, participated in these games. The first Far Eastern championship Games were held in manila in 1913. Once it was well organized, many other Asian nations came forward to take part in the Games. It was discontinued in 1938 when Japan invaded China.

Hi pals. Now I like to share my view about Air conditioners. Air conditioners were meant for industrial purpose. It was not used for human comfort alone. Carrier received this particular idea while waiting for a train. It was a foggy night. He was thinking over the problem of temperature and humidity. He also thought of a few ways to control them. But the time the train arrived he had decided something in his mind. First of all, Carrier had an understanding of the relationship between temperature, humidity and dew point. And the rest is only history.
Industries profited most from air conditioners. The quality of many products increased due to air conditioning. Willis and six other engineers formed the Carrier Engineering Corporation ion 1915. The company was dedicated to improving air conditioning technology. Many more experiments were conducted to make it more and more effective. In 1924 became a grand success.

Hi dude! Hope you all doing good and I am very cheerful to see you all again here. And, at the moment I am going to share you all my acquaintance about Arafura Games. The Arafura Games is a multi- sport even. It is usually held every 2 years in the Australian city of Darwin, in the Northern Territory. It is an international event. The Games were first held in 1991. The most recent Games were held in 2007. Almost 25 nations and over 3,000 athletes took part in this event. From 2005, it will include events for athletes with physical disabilities. The name of this sport event comes from the Arafura Sea which lies between northern Australia and Southeast Asia. The games were known as the Arafura Sports Festival up until 1997. The Games were cancelled in 2003 due to concern over the SARS virus.

Hi dude. Willis Havilland Carrier was the inventor of air conditioner. It was in the year 1902. Willis Havilland Carrier graduated from Cornell University in 1901 with a Masters in Engineering. The next year itself he built the first air conditioner.
It was first used in one Brooklyn printing plant. It was really a blessing for the owner. Fluctuations in heat and humidity in his plant had caused him some problem. The dimension of the printing paper changed a little due to heat. It was a factor that would affect printing. The air conditioning machine created a stable environment. As a result four-color printing became possible
He got the patent for the new inventions in 1906. In fact, it was the first of several patents awarded to Willis Havilland Carrier. The recognized ‘father of air conditioning’ is Carrier. But it was Stuart H.Carmer who introduced the term; air conditioning’. Stuart was a textile engineer. He used the phrase ‘air conditioning’ in a 1906 patent claim. He had filed it for a device that added water vapor to air in textile plants – to condition the yarn.

Hi dude! Hope you all doing good and I am very cheerful to see you all again here. And, at the moment I am going to share you all my acquaintance about Airbags. In 1971, the Ford car company built an experimental airbag. General Motors tested airbags in Chevrolet automobile. It was in 1973. They were only sold for government use. Oldsmobile Toronado (1973) was the first car with a passenger air bag intended for sale to the public. Because of these air bags many souls are saved from accident. This bag was greatly welcomed by the public. It sounds good in all the countries. More over nowadays many leading company started production of air bags with full effort. Many competitive companies are using more advance technology to develop air bags. Air bags are must for the safe journey it greatly helps to the people’s life.

Hi pals. Airbags are used for automobiles safety. They are cushions that can be filled with air. They built into the steering wheel, dashboard, door, roof, or seat of a car. They use a crash sensor. When there is a crash, they expand immediately. Such am expansion can protect the passengers from the impact of an accident.
Allen breed was the inventor of the airbag and crash sensing technology. Breed invented it in 1968. However, many attempts were made by some inventions
Walter Linderer and John Hedrick were two of them. Water was a German, where as John was an American. Walter Linderer’s airbag was based on a compressed air system air was released either by bumper contact or by the driver. However, it was not much effective. The reason was that compressed air could not blow the bags up fast enough. John Hedrick made his invention in 1953. It too was not much safe.
