A farmer hired engineers, physicists and mathematicians to encircle the largest area with the fewest fences. The engineer made a circle with a fence and claimed that it was the best design. Physicists pull the fence into a long straight line. Assuming that the fence is infinitely long, they think that halfway around the world is big enough. The mathematician laughed at them. He fenced himself with few fences and said, I'm outside now.

We should be good at thinking from multiple angles.
