Spock

Mr. Spock, often just referred to as Spock, was a Star Trek character that Rose Tyler associated with a more "professional" approach to the use of technology. Whilst in 1940 London, she once bemoaned the Ninth Doctor's primitive reliance on the sonic screwdriver and conversation as his primary investigative tools. She demanded that he "give [her] some Spock" in their search for a downed Chula ambulance. Later, in an effort to explain to Captain Jack Harkness whom the Doctor was, she gave the Time Lord the alias "Mr. Spock", because she suddenly realised she didn't even know his proper name. (DW: The Empty Child)

Donna Noble also seemed familiar with the character of Spock, when she compared the Tenth Doctor's method of reading a person's thoughts to that of Spock's "mind meld". (BBCR: The Nemonite Invasion)
