: The word "relativity" was coined by Maxwell, and it became popular from Poincare calling the "principle of relativity" the idea that different inertial frames are indistinguishable. When I said that string theory assumes relativity, I meant primarily that it assumes Lorentz/Poincare invariance. The influence of relativity on physics has been primarily in electromagnetism, not gravity. The nonlinear gravity effects are barely detectable.

:: * Again, general relativity is about gravity. Special relativity is not.
:: * No one is saying "quantum mechanics" means "relativity". However, the article you linked to referenced quantum electrodynamics (a subset of quantum mechanics) which does incorporate special relativity. Moreover, while general relativity and quantum mechanics are difficult to reconcile, special relativity and quantum mechanics aren't and doing so has produced [[Quantum electrodynamics|the most accurate theory in physics]].
:: * No one is saying "invariance" means "relativity". For example, Galilean invariance contradicts relativity. However, a special type of invariance, Lorentz invariance, is fundamental to both special and general relativity (it holds locally in general relativity). String theory is Lorentz invariant.
