Fundamental interaction and the strong interaction. Their magnitude and behaviour vary greatly, as described in the table below. Modern physics attempts to explain every observed physical phenomenon by these fundamental interactions. Moreover, reducing the number of different interaction types is seen as desirable. Two cases in point are the unification of: Both magnitude ("relative strength") and "range", as given in the table, are meaningful only within a rather complex theoretical framework. It should also be noted that the table below lists properties of a conceptual scheme that is still the subject of ongoing research. The modern (perturbative) quantum mechanical view of the
Algebra of physical space equation, for an electrically charged particle of mass "m" and charge "e", takes the form: where e is an arbitrary unitary vector, and "A" is the electromagnetic paravector potential as above. The electromagnetic interaction has been included via minimal coupling in terms of the potential "A". The differential equation of the Lorentz rotor that is consistent with the Lorentz force is such that the proper velocity is calculated as the Lorentz transformation of the proper velocity at rest which can be integrated to find the space-time trajectory formula_31 with the additional use of Algebra of physical space In physics, the
