On 17 November 1999, 21st February was announced as the international mother language day by UNESCO. It was about the language movement of 1952 of Bangladesh. In 1952 the people of Bangladesh (then east Pakistan) protested against the inappropriate decision of making Urdu as the state language of then Pakistan. When this situation got kind of difficult for the Pakistani govt, they invoked a limited curfew to prevent the movement. But students broke the curfew and brought out possessions and Pakistani police fired on them and a number of students were killed. Four of them were Rafiq Uddin Ahmed, Abdul Jabbar, Abdus Salam and Abul Barkat. The day was so much tragic. The Bangles are the only nation that sacrificed so much for there language. That's why the day was to be remembered and was given recognition as the International mother language day.
Giant African Snail
One of the world’s most destructive pests of fruit and vegetables is the giant African snail. It grows up to 30 centimeters long and weighing up to a kilogram. And its around 500 species of plants including, papaya, peas, peanut, cucumbers, rubber trees and most varieties of beans, cocoa, and melons.
In the family Achatinidae, Giant African land snail could submit to two genera and three species. They are usually set aside as pets in countries like UK. Leafy greens, vegetables and fruit items are suitable for them. Groups of snails will strain effectively and within every three days, eggs ought to be detached. They disposed of after freezing for 48 hours. One snail can lay up to 1200 eggs a year.
The Giant African Snail which scientific name is 'Achatina achatina', in the genus Achatina, also notorious as the Agate Snail or Ghana Tiger Snail. It grows to be the prevalent land snail on Earth.
In many countries Giant African snails are considered as a weakness and purposeful prefaces to new locales are conceivably liable for the pest’s extend to Indian and Pacific Ocean islands.
These snails are genderless. Each individual has both male and female reproductive systems.
The species is steamy but it can bear cold or adverse conditions because it can move away into its shell and stay hidden for more than a few months. Hidden snails can lose 60 per cent of their weight and come into view as dead.
The introduction of this pest on crates, on plant material in or on shipping containers, machinery and motor vehicles is he main risk for Australia. Eggs may also be carried in soil.

Eiffel Tower
Eiffel Tower Biography
The iron structure was built between 1887 and 1889. It was actually built for a world's fair called
Exposition Universelle. 18,038 pieces of puddle iron, which is a very pure form of structural iron, was joined by three hundred workers, using two and a half million rivets. The tower is an open frame without any intermediate floors except the two platforms unlike modern skyscrapers and so the risk of accident was very much. The structure took more than two years to complete. During building the tower was much criticized. Newspapers of the day were filled with angry letters from the arts community of Paris. After all this the tower opened in 6 May, 1889.
Things about Eiffel Tower
Represents a new taste or consideration of beauty in architecture. The tower attracted large crowds of visitors and brought in tourists. And there costs helped Francis economy. During the world fair in 1889 around two million tourists came to see the Eiffel Tower. Even from the first year of ticket sales income, The government recovered its costs of constructing the Tower.
The tower is 320-meters long.It was the first structure to surpass 300 meters in height, and was the tallest structure in the world from 1889 to 1930). a few people thought that it would interfere with the flight of birds over Paris. But after all the tower was greatly admired by the world.

Sundial Watches : The begining of clocks
Most probably the gnomon was the first device to indicate the time of day. The gnomon consisted of a vertical stick or pillar. Casting a shadow or throwing light onto the dial face or dial plate, the surface of the Sundials, it indicates time of day. Mainly the length of the shadow indicates time. The shadow rotates clockwise as the sun raises from one side to the opposite side or more like earth rotates counter clockwise as a result we see the sun raising at the east and going down at the west. This was the history of the time at 5000-3500 BC.
At the time of 2500-2000 BC obelisks were build by Babylonians and Egyptians. The obelisks which shadows formed a kind of sundial. Those made possible citizens to divide the day into two parts by indicating noon. When the shadow at noon was the longest or shortest of the year, they showed the year’s longest and shortest days.
A sundial comes from Berossus, a Babylonian priest and author in 300 BC. The sundial is a cubical block into which a half-sphere is cut. At the center a small bead is fixed.
Introducing trigonometry into mathematics, supply the tool for plotting hour lines with simple arithmetic calculations instead of the more cumbersome geometric constructions. This is the story of 150 AD.
At 1300 AD, The first all-mechanical clock is made which is a large iron-framed structure. It is driven by weights. The great age of the European sundial is 1500 - 1800. Sundials gradually come into use with equal hours.
In 1979, LLC, the founder of Accurate Sundials, starts designing, building and testing many types of accurate sundials. For each major type of sundial to make the 174 calculations, he designs a computer program which go into each custom design.
Along with expert support in computer aided design and machine shop technology, the knowledge gained by Accurate Sundials, LLC in 24 years of research, results in the attractive offering of elegant and accurate solid brass, copper and aluminum sundials.
After clocks were invented, people did not stop to make sundials. Until watches were invented to make the way of keeping time easier for people to tell time wherever they were, the sundial was still the most popular way of keeping time. At present most of the people have sundials in their gardens. They use them for decoration rather than as a way of keeping time. Though the invention of the digital wristwatch give comfort to the people that they no longer need to carry around a portable sundial, but sundials should not be forgotten by modern people. The making sundials remain one of the most reliable methods of telling time of momemnts.

A painter, Johannes Vermeer created a paint named
" Young woman playing a guitar" in 1672.
The earliest form of guitar was created in 1779,
by a man of Neapolitan decent,
whose name was Gaetano Vinaccia (from Vinaccia family).
