One of the issues resulting from this, is that taking the sectional view of things, while applying relativity theory, leads to a removal of a number of degrees of freedom.

These dynamical laws can be written in equation form, and additionally, each variable describing a system is a degree of freedom.

Can also be thought of as some of the Degrees of freedom a some physical system, though regard the difference between the mathematical representation of the physical system and the system as it exists, or is idealized.
