Science and us

   The origin of science is your questions asking why. One day Newton saw a falling apple in the garden. He thought why did the apple fall and there must be something that pulled it to the ground. Then he discovered the law of gravity in this way. The weight of things is gravity. Everything has it's weight because the earth pulls it. When you hear this theory, you may ask why can a plane go up into the air.

   You can throw up a ball. If you throw the ball up with a greater power than its weight, it goes up. But it is restrained from the pull of the earth. The same thing can be said of a plane going up.

   Manind created the way to get away from the earth. It is a rocket. The rocket's power is great enough to get free from the pull of the earth. Two American teams landed on the moon. They searched around the moon with a large rocket. The rocket can get away from the earth into space because of such a great speed. The speed must be more than 24000 miles an hour. About thousands people worked together to send only two teams. Not only people but also the computer helped it. It told them when to start and where to land.

   We come to be able to do anything thanks of science, but can you feel really happy with it? Many people have various ideas. This is not an easy question. When you grow up, you should try to find an answer for yourselves.
