And it's a great example of the whole process of physics of trying to coalesce many different things down into one explanation. I imagine even cavemen would get static electricity in their hair would stand up. But for them, it was probably just magic or they had no way to grasp that there would be a reason for that. Exactly. In the process of science is one of trying to develop like an explanation for these things. How can we unify different phenomena that we see? The static electricity in your hair and
