Shape of the Earth :
During the classes, the sister-in-law asked, "Do you have any idea about the size of the earth?" 
Sohana stood up and said, she said, almost round around the world, then she wondered why our world is 'round'? 
But when I came home from school, If I gave up on the flat surface, then the earth is round, and with another eye, one breaks and half of it Uche them. 
They wiped out the rest of his little part.
First you see the picture on your virtuous circle, the second middle class, and the third flat surface? When a little part of an object comes in our eyes we do not get the full idea of the sky. So the world does not seem to be round.
Earth-sized concept: Greek philosopher Homer thought the earth was flat. When it reached the surface of the stomach, it was feared to fall down. Indian astronomer and mathematician aryabhatta said in the fifth century that the world's sphere of spheres is unrealistic.
