Re: Things you can do from Astrometrics -but not from bridge/engineeri I believe the real-life reason was because they needed to give Seven of Nine a big role and her own "area" other than the cargo bay. Forget where I read and/or heard that, but I believe Kate mentioned it in an interview that they built Astrometrics FOR Seven. Which I have no complaint about, I thought it was awesome. Who wants to be stuck in the cargo bay all day. And you knowwww Seven would not want to take orders from B'Elanna in Engineering (even though Seven's head probably comprises all of the knowledge of the entire engineering crew...). But yeah it seems as though science/engineering/astrophysics were her strong suits and Astrometrics kind of emcompasses all of those skills in one.
