I want to take back ‘Retard’. Because I want it to apply to things that are infuriatingly stupid, instead of it being used as a derogatory term towards special needs people.

    So I think there’s a bit of crossing of wires (pun maybe intended) when it comes understanding both concepts. For water a valve acts as a door, open doors let things through, closed doors block things from moving.

    For circuits, I believe closed comes from a more mathematical thing where closed more means without holes/gaps. So the circuit is open when there is a gap in the circuit as a whole.

    I think the real confusion occurs when in high school physics classes there is a segment about flowing water in preparation for the next chapter on electricity and circuits.
