And then we have "screens" which are another name for shields I guess. I think they went back and forth before finally settling on "shields."
I never understood why, when danger appears and time is of the essence, the Captain has to order someone else to "raise the shields"...often numerous times before someone gets around to raising them. Why can't the captain just hit a button on his chair? Or better yet, why can't the computer automatically raise them under certain conditions?
