    Does anyone on this list know why the symbol s is used for displacement =
    in physics? If I had to guess I would guess that is to differentiate it =
    from the concept of distance which is not a vector. But it looks to me =
    like it would be much less confusing to the students if we used d for =
    the scaler quantity distance and d for the vector quantity displacement.
