My favourite in this direction is an application of Noether's theorem to public relations: Sha, "Noether's Theorem: The Science of Symmetry and the Law of Conservation", J. Public Relations Research, 16 (2004) 391-416.
I quote from the abstract:
Noether's Theorem shows that symmetry-or change-can only exist simultaneously with conservation or invariance. For public relations, the implication is that an organization can behave "symmetrically" while maintaining certain beliefs, principles, or purposes that will never be relinquished. A case study of the Democratic Progressive Party (DPP) on Taiwan using participant observation (13 months), qualitative interviews (n = 22), and a quantitative survey (n = 166; response rate = 28.77%) showed that the organization exhibited symmetry by reaching out to external publics, engaging in dialogue with them, and expressing openness regarding Taiwan independence. Simultaneously, the party conserved its interests in gaining power and establishing an independent Taiwan. Recent electoral victories of the DPP suggest the effectiveness of symmetry-conservation for public relations practice.
