Character mistake: When Chekov is discussing the plan to hide behind Saturn, he says, "...if Mr. Scott can get us to warp 4...". But on the viewscreen, it shows they are already traveling at warp 4.31. (01:34:40)
Character mistake: When the Enterprise first comes under attack from the Narada, Captain Pike gives the order "transfer power from port nacelles to forward shields" (confirmed by subtitles). As the Enterprise has only one port nacelle, his use of the plural is not correct.
Answer: Kirk's never met Uhura - he wouldn't know where she's from. When he asks her name, she says that her name is "just Uhura" - Kirk's expecting to hear two names, first name and surname (just as he introduced himself as "Jim Kirk"). As such, his first question is to ask whether they don't have surnames on whatever world she comes from. As it happens, she is from Earth, she just doesn't want to tell him her full name; he doesn't know that, so he's making assumptions that are, in this case, completely wrong.
