Story of Helicopters
by Prof. Saqib Rasheed
It was inevitable, perhaps, that the first fairly practical ideas on flying machines should have come from the great Lenardo da Vinci. Aeronautic-ally speaking. Leonardo produced one of the first drawings of a parachute, he devised a helicopter. The word "Helicopter" comes from the Greek helix ( a screw) and pteron (wing), and Leonardo's concept was just that - a spiral wing that would "screw" itself up into the air. Throughout the years in which aeroplanes were becoming more practical and widely accepted, each increase in speed and load carrying ability, seemed to be accompanied automatically, by higher take off and landing speeds, longer take off and landing runs. Most accidents occurred during these periods of flight.
One obvious substitute was the helicopter which had been tested successfully in France as far back as 1907. The breguet Richet Gyroplane No. 1 had lifted itself from the ground, carrying a pilot. Shortly afterwards Paul Cornu worked on tandem-rotor helicopter.

The idlers do not get anything. this world is not a place for recreation and we are not on a pleasure trip. If we wish to survive, we have to make our place by our won efforts. Here we have to rely on our own strength and means so that we may lead a happy and satisfied life.
Struggle is very essential for the development of a country.

Reality Never Changes
By: Tariq Dothraki
This is the story of how little changes can turn out to be so great. Once there lived a great artist, Leonardo Da Vinci. He usually made religious paintings that had great impact on the minds of the viewers. One evening, an idea clicked his mind. He thought why not let people see Jesus with the devil, for once. He thought about painting a dinner with both in it. He did not have the slightest idea how to sketch Jesus. So he searched for someone perfect enough to pose for him. Once during his search, he came across a man known as Jacqen Bin Hagar. He saw a nobody. But he seemed perfect. He prayed, he respected, he loved. In short, he did everything a simple man can do. when da Vince asked him to pose for Jesus, he being deeply docile, did as he was asked. Leonardo, now satisfied with making Jesus part cane to the more difficult part. He had to search for the devil now. He had no idea where he could find such a perfect example of the worst. Years of his search bore no fruit. When he was most dejected, he cane across a man whom words cannot describe. His attitude was nasty, his clothes were bad. He loved no one, respected no one. He had no love or gave no thought to anyone. Leonardo spent many days until he persuaded him to successfully pose for the devil. After the painting had been made, the man exclaimed that somewhere before, he had seen a painting like this. It was indeed the man who had, years before, posed for Jesus! He was in fact none other than Jacqen Bin Hagar. Leonardo was so amazed that at first words were stuck in his mouth. Then later he asked what was it that had changed the best into the worst. Jacqen gave a simple reply.
" I loved those that never knew their importance until I came and they were the same who never gave me importance. I respect those who didn't know what respect was. Even I prayed to them who made no response. So I came to the conclusion life is not just. In the end everyone will die. So, it is upon you to live the hardships of Jesus Christ or the free life of Lucifer."
This made such an impact on Leonardo that all of his life he could not forget the Jesus who was called Lucifer.
The Moral of this story is not that I am saying you should lose all hope like Jacqen. It is that you should learn to love others, respect others and pray to Him Who considers you important and never lose all hope till eternity.

Respected Sir,
Assalam-o-alaikum!
I
am writing this letter to inform you about the traffic jam issue in front of
our school. People do not know about traffic rules. Due to this, nobody follows
the traffic rules because there is no traffic police on this road. I daily observe many walkers, joggers and
vehicles violating safety rules on the road. They create problems for others as
well. Therefore, the students often get late for school.
I
would like to request you to please solve this serious issue by giving the
knowledge about the traffic rules to us.
Yours sincerely,
X.Y.Z
