| Jul 6, 2016 at 1:10 | comment | added | dmckee --- ex-moderator kitten | I applaud Daniel's answer that goes into the historic process, which is not something I have more than a passing familiarity with. Nor do I think it is terribly important for students in the intro class, but I really want them to be able to convince themselves that this model is constrained by observations they can reproduce. | |

| Jul 5, 2016 at 14:20 | comment | added | levitopher | I like this answer best, but I've added my own to illustrate that one of the reasons we get a binary answer is that we are only asking a binary question. If we had measured the magnitude of the forces involved, we would be forced to consider many kinds of charges, some bigger than others. | |
| Jul 5, 2016 at 10:19 | comment | added | David Z | Given that this isn't History of Science and Mathematics, I think our concern here is to demonstrate how one could have known there are two kinds of charge, not to give a historically accurate retelling of how they actually did figure it out. | |
