Abstract
This essay analyzes the dimensions of the physical quantities. Planck units are used as identifyers of the physical quantities. Quantity tables reveal interesting patterns like alternating scalar and vector quantities. This essay advocates that Nature is fundamentally continuous and that phase is responsible for the fact that certain physical quantities can take only a countable set of discrete values. The introduction of phase leads from a relativistic classical mechanics to a relativistic quantum mechanics. In a somewhat broken analogy we can say that continuous media like water or gas also produce discrete physical objects like dropplets or bubbles. Interesting is the finding of a quadratic metric as the very essence of the Maxwell equations. If we 'throw' this pure electromagnetic metric into the pure gravitomagnetic metric then the result are the Maxwell equations. Also interesting is the finding that the fine structure constant is the ratio of two different planck constants. Because of the introduction of new quantities I often use the names of the quantities instead of their symbols.
