For those who have known me a while, you know that I am fascinated by how our eyes and brains perceive the world. What we "see" isn't always what is there.
The moon is a great example. I tell this often, so bear with me. The moon seems very large when it rises over the horizon early in the evening. Later at night, the moon seems to be quite a bit smaller. The moon has a circular orbit about the earth, so the size difference isn't a result of distance from us. Instead, it has more to do with the distance from the horizon. We see the moon as being larger when there is something to compare. When the moon is high in the sky, it "looks" smaller because we can't compare. You see what isn't there.
In that vein, here is a very interesting paragraph for you to read.

It is amazing! Of course, this is also why it is so hard to proof read your own work. You see what you want...not what is tehre. ;-)
PS
The best part is that spell check only identified one misspelled word!
