> * marketers and politicians may disagree He. Whenever people make claims that violate [math + the laws of physics], invariably it's those people who prove to be at fault. Leading to a favorite of mine: "Math combined with laws of physics are more reliable than people." In other words: where possible, measure & do the math! What you find = reality (aka truth). Claims from people saying something else, can then be safely ignored (okay.. up to the point where measurements or the math itself is found to be in error).
