::::I have a problem with the wording of "The formula E=mc² has little relevance to situations where mass is not converted into energy such as chemical reactions or electrostatic interactions." (I believe this is part of "AugustO's version" but correct me otherwise.) The theory of relativity doesn't classify some types of reactions as "mass is not converted to energy". It says that whenever there is a change in energy, there is a corresponding change in mass. It doesn't matter if it's two deuterons sticking together to form a <sup>4</sup>He nucleus, or two refrigerator magnets sticking together. Yes, the mass change is immeasurably small for non-nuclear reactions, but the formula still holds.
