If '1' is the unit in real (1D) space, '1' and 'i' are the units in complex (2D) space, then surely one more unit ('j' ?) will be needed in 'whatchamaycallit' (3D) space ?
Also consider that if multiplication by 1 in real space is an identity operation (keeping things unchanged) and multiplication by i in complex space is a counterclockwise planar rotation by 90 degrees, what will multiplication by 'j' in 3D space mean ? Mind that now there are two addtional (basic) planes yz and zx to rotate in ?

For simplicity, assume that I'm standing erect and still, like a statue, on a motorized skateboard that can vary its speed as I wish. Mind that if I move faster to cut the time, the rain slants at me more and I present a larger surface for wetting..

I have seen cases where the winning answer, by vote, is simply wrong. In science and mathematiics (my area) , there are capable people who are probably willing th check a voted answer for accuracy. If an answer is incorrect, a tip could be given and the question reopened. Getting points with wrong answer is bad.
