What is cool?

I saw this google doodle, and thought it was cool.

Then I started to wonder what that meant.

Cool is a place holder, for I don’t know what’s going on here, but I like it. Looking at something that is cool, we generally like what it is, but don’t understand the behavior even if the components make sense to us. We could put in the effort to understand, but we’d rather chalk it up to being cool.

As opposed to cool, interesting is something that we want to know more about. In grade school being cool was the goal, after aging, interesting is more important.
