The story that seems to be on Slashdot.org for a long time ago, the author's gambling said it is true.
A Professor of Mathematics, a university, found that his own sewer is blocked, please come to a plumber to repair. After 30 minutes, the water pipe is dredging. Professor is quite satisfied with the performance of the plumber, but when he saw the bill: "What is it! In 30 minutes, you will receive the money for a month's income!. I am going to be a water pipe! ". Plumber said, "You can go. Our company is looking for someone. It is also a training. But you have to say that you just graduate, the company doesn't like people who are too high." So the professor will participate in the training, when the water pipe is used. His income turned three times. He is much older than before. A few years later, the company suddenly decided to raise the cultural level of the water pipes to junior high school, and asked the workers to go to the school. The first class of the night school is mathematics. Teacher wants to first look at these water pipelines, so he casually smashed the formula of writing a circular area. This professor was sucked, but he had forgotten the formula of the circular area is Pi X R ^ 2. So he had to derive from his head: dividing the circle. However, the result he derived was negative pi * r ^ 2. ING, professor never came, the result is still negative. He is very embarrassed, so he returns to dozens of water pipes sitting in the classroom for help. I saw that these colleagues were handing over, and they gave him: exchange points up and lower limits. :-D
Lesson: If you learn mathematics (the same as programming), it is not as good as a water pipe.
