How can materials be waterproof or air tight if atoms don’t touch?
In: Physics
I’m going to kill whoever first said that “atoms don’t touch”. It’s such a misleading idea that confuses literally everyone. Electrons can’t touch each other because the concept of “touching” doesn’t make sense at quantum scales.
Atoms interact with each other via their electron clouds. That’s what you’re thinking of when you say something is touching something else.
