>Nah, it's a measure :) lol tell me you're a physicist without telling me you're a physicist :) >with minimal confusion. i think this the key thing that people that do a little math but not an immense amount don't understand: notation serves the same purpose as short hand in any other speech/communication. locally it's crystal clear, where local can be as small as that paper, that subsection, or just that paragraph (cf "the distinction is clear from context" lolol). i've written papers myself where i switch notations midstream for efficiency's sake (try defining tensors without bases but then try manipulating them without index notation...) but taking notation for granted is just as likely to get you into trouble as taking an API's promises for granted (in fact they're exactly the same things - leaky abstractions).
