ex: a volume of gas (a cloud in the sky) has a water density per volume, which is a 4 dimensional differential equation... but since it changes in time it's really a cover of 5 dimensions. And then you get to the class 'diff EQ' which is just more of the same.
ex2: A quaternion is a 4 dimensional quantity that describes orientation in a 3 dimensional space(hmm domain would be a more generic term for space) but says nothing about it's position or velocity which are yet more field equations. (this describes a field of rotation)
right... there are things 'like' particles and *like* waves though... there are things that behave in such a way that a wave model fits... much like inertia does to induction, and spring physics to capacitance.... that doesn't mean a capacitor IS-A spring, but they can share the same base classes.
