Long ago, an artist took in three students
One day, the artist gathered the students and wanted to test them. He gave each student each a piece of paper, telling them to see who can draw the most camels on the piece of paper.
The students thought for a while and began to draw.
The oldest one uses the thinnest pencil and drew a lot of little camels. After drawing, he was very proud, thinking that he drew the most camels.
The second one thought: the paper is only this big if wanting to draw the camels, how should he do it? So he drew a lot of camel heads. He did draw more than the oldest student.
The artist looked at both of their work without a bit of emotion. When he looked at the littlest student's work, he kept nodding his head. Turns out he only drew a few curved lines, meaning the road in the mountain, a camel walked out from the mountain, the other one pokes his head out from behind. When the two oldest students saw the artist's reaction to the artwork, they thought it was really strange.
The artist said: "You guys look at this, though the art only shows two camels, they walk in a line, so you don't know how many will come, doesn't this show that there is an unlimited amount of camels there?"
The two students were shocked.
