Thickness Memes

The claim that "hair is the thinnest thing in the world" is actually incorrect. Human hair averages 70-100 micrometers in diameter, while school toilet paper measures approximately 0.1 micrometers thick. Still, both pale in comparison to the thinness of one's patience after the third consecutive failed experiment. The real thinnest material is graphene at just one atom thick (0.33 nanometers), but Harvard scientists were probably too busy fighting for parking spaces to measure that properly.
