The teacher was vividly describing the discovery of the law of gravitation. He tried to make the children impressed with its importance.
He said, "Isaac Newton was sitting on the ground looking at the tree. An apple suddenly fell on his head. It led him discover gravitation." And he added, "Isn't that wonderful?"
The "smart boy" in the class replied in a high voice: "Yes, teacher, and he was very fortunate. If looking at his books, he wouldn't have discovered anything."
