I don't know about scientists, but I had an instructor once who was fond of picking on engineers:

"If you asked an engineer to define the process of taking a leak, he or she would come back in an hour with a set of blueprints, a bill of materials, a list of required permits, and a notepad filled with mathematical equations showing you why taking a leak was utterly impossible. Geez, when are these guys gonna' learn that it's not always so difficult!"

My apologies to any engineers present......... kinda! There are days where I can appreciate his sentiments.....

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
