The great mathematician Euler was not liked by his teacher when he was a child.

Once, he asked the teacher: How many stars are there in the sky?

The teacher said: There are many, many, and the number is not clear.

Euler asked: How could it be unclear?

The teacher said: The stars in the sky are inlaid by God.

Euler asked: The sky is so big, so high, and there are no escalators on the ground. How did God inlay the stars one by one on the screen?

The teacher said: This is God’s business and we ordinary people cannot know it.

Euler asked: God should know how many stars there are in the sky, right?

The teacher said: He doesn’t know either.

Euler felt strange and asked the teacher again in a complaining tone: He had set these stars himself. He should know. How could he not know?

The whole class was in an uproar and followed Euler in complaining: This God is too careless!

The teacher was asked again and blushed, not knowing how to answer.

A surge of anger suddenly arose in the teacher's heart. This was not only because a child who had just started school asked the teacher such a question, which made the teacher unable to step down. More importantly, the teacher values ??God above all else. Little Euler actually blamed God for not remembering the number of stars. The implication was that he doubted the Almighty God.

In the minds of teachers, this is a serious problem.

Soon, Euler was expelled from the school because he doubted God.
