Title: "Maxwell stress tensor. An elementary introduction in terms of differential forms"

It is well known that the two plates of the electric capacitor attract each other. It can be interpreted that the electric field existing between the plates exerts forces on the plates. The force is proportional to the area of one of the plates. The linear mapping from the surface bivector (of the plate) to the force one-form is a component of the stress tensor of the electric field. It describes the tensional stress. A reasoning applied to stretching the area of the plates allows to derive the two other components of the stress tensor. They describe the compressional stress. If the time is left, similar considerations could be presented for the magnetic field. In the whole presentation, the word "perpendicular" will be never used, because it is a metric-independent approach. Only the word "parallel" is allowed.
