illusion：幻覚，幻影;
perspective: 遠景の見通し;

As I was leaving the university on Monday night, I saw the moon rising. It was almost a full moon. The moon was full the following night. It looked much bigger than it did an hour later in the sky. Scientists call this the “moon illusion.” Some scientists believe that the moon seems larger than usual at the horizon because we know that the horizon is far away. Up in the sky, however, we have no sense of perspective. We can’t compare it to anything else. If it’s clear this evening, go out and try to see the moon illusion. (by Prof. Douglas Jarrell)
