# Derivable Concepts in Mechanics and Electromagnetism

In Classical Mechanics, one of the possible foundations is based on three concepts aka mass(equivalent to energy), length and time. This is a foundation because we can model everything ( pressure, position, volume, acceleration, velocity, temperature ) from those, even if the description of more complex things ( like temperature ) in terms of the foundations might be a bit complicated and further abstractions/definitions would prove to be useful.

So, it seems like the other big part of classical physics is Classical Electromagnetism and i was looking for a possible foundations there that is able to model everything in Electromagnetic Theory ( from electrostatic, to electrodynamics, to maxwellian equations to electromagnetic waves, to optics ),

Could a canditate 3-uple for a simple foundations of Classical Electromagnetism be charges ( or difference in charge ), length and time. This would be just substituting mass ( equivalent to energy ) for differences in charge ( which is equivalent to energy ).

Is this a good enough simple foundations for Electromagnetic Theory ?

If not, can anyone suggest me one ( preferably a simple one in terms of math ) ?

• @nerdy I think that a fundamental system of concepts should be parallel to the fundamental system of units. In c.g.s. we have cm, gram, sec., s.t. length, mass, time are enough for mechanics. Though I don't understand why you separate electromagnetism. So you should add to c.g.s. the statC, s.t. the system of concepts becomes length, mass, time, charge. But what about magnetic field? Well, the unit of magnetic flux, Wb = V $\cdot$ s, s.t. no additional unit should be introduced, and no additional basic concept. – Sofia Feb 12 '15 at 20:59
