Principle of material objectivity

Principle of material objectivity is an obsolete term and should be replaced by principle of material frame-indifference. ("I was responsible for introducing the obsolete term in 1958 and now regret that I misled a lot of people", Walter Noll). Here is a precise statement of the Principle:

The constitutive laws governing the internal interactions between the parts of a physical system should not depend on whatever external frame of reference is used to describe them.

(See parts [1] and [2] of "Five Contributions to Natural Philosophy", available on the website [http://www.math.cmu.edu/~wn0g/noll] .)Note: A frame of reference is very different from a coordinate system. Contrary of some people's opinion, the principle has nothing to do with coordinate systems.
