You have just seen me untie the knot, dissociate the electrons, or what you will.
Steel and electrons and wires and robotic brains were inflexible.
But when you rubbed them together, you rubbed some of the electrons off the wool on to the comb.
But you remember that when we want to get these electrons to do work we must make them flow.
The electrons could not get off the hair easily, so they stayed there.
Metal and electrons reason well, but not in a human fashion.
Electrons are to be found everywhere, forming part of every atom.
These electrons are the key to half the mysteries of matter.
Is there a nucleus, then, round which the electrons revolve?
In other words, we believe an electric current to be a flow of electrons.
