The reason star trek employed so much scientific jargon is because it is in keeping with the premise of the show (TOS, TNG and VOY primarily).
Which is as a medium to express not only ideas but languages of reason. And science, like logistics, is a language of reason. Which is why it is a very important component of star trek that should never be brushed aside.
It shows that humans have evolved to seek out truth, in whatever form, through evolved systems of scientific exploration.
This is what I liked so much about TNG. It didn't insult the intelligence of the viewer by coming up with things (like red matter for example) without at least trying to explain it in some rational, conclusive way. Episodes like cause and effect illustrate this.
