As a physicist I am completely baffled and confused. What do you mean by rank of a quantity? Do you mean the size of a vector/matrix? If
I understood Olegs post about rank such that it was something that would allow to distinguish energy from torque, e.g. Is there such a thing? Off the top of my head, I cannot think of a situation where you might want to add energy to torque, even if in the SI system they have the same dimension (Nm). Same thing for angular velocity [rad/s] and frequency (1/s). You probably don't want to add both, even if in SI they're both in s^-1. Is this maybe a deficiency of SI? Would it make sense to add the unit "radians" that is used colloquially anyway, to the system?
