"Does the philosophy remain intact?"
Absolutely. Rather than going for examples from science, can you precisely tell me how the usage changes? Not examples, but the actual usage.
Ah, I see. Certainly the sentiment is there. So what exactly are you saying? If the mere gist or sentiment of an idea carries through with successive revisions of a definition, all definitions are equivalent? In an academic setting, is it a sufficient standard to merely convey the sentiment of an idea, however vague or ambiguous that conveyance may be?
