I know one of the most horrific moments of my childhood was when I was informed that no matter how often I bathed, and no matter how hard I cleaned, there would be dust mites all over myself and everything I held dear. They are, apparently, all over everything.
Quite frankly, it still freaks me out.
I was just thinking about the first scientists who developed electron microscopes powerful enough to look at the surface of a dust mite. I wonder if, just for a second, the first scientist to put his eye up to the eyepiece might have wondered: “On the surface of this dust mite, am I going to see little cars and little cities, with little tiny people, wearing little tiny hats and little tiny sweaters, walking around on their dust mite, completely unaware?”
Because I would.
