Humanist Archives Vol. This discussion is getting irritating. Look, there is such a thing as a bi-stable electrical device. Think of it as something that with high probability is either in one state or another, but if it finds itself inbetween it tends to get into one of its two stable states.
Light switches are such devices.
Bi-stable devices have played an important part in the development of computers because they directly mimic binary arithmetic. When you build a computer you pick a number system for it. You can offer the programmers any number system you want as the most basic way of dealing with the computer. However at the electrical device level it would be very rare to encounter n-stable devices being used. It is much easier to gang together a bunch of bi-stable devices to pretend to be something else.
