Wk=mMv2/2

The abstruse title "Wk=mMv2/2" is the physical equation for a molecule's kinetic energy, and it refers to the images shown in the film: They were created by zooming at coincidentally photographed individuals on postcards. As a result of the extreme enlargement, the grid of the cards' printing is made clearly visible and the figures, many of which are only a few millimeters high in the original, are greatly abstracted.
