Fascinating! The crew of the U.S.S. Enterprise would hear this word spoken by their Vulcan science officer many times as he mans the science station abourd their starship, as shown by this 1996 Star Trek Hallmark Keepsake Ornament. Although Mr. Spock was half human and half Vulcan (his mother was Amanda Grayson, a human, and his father was Sarek, a Vulcan Diplomat), it was always clear that Spock's mid was trained in the Vulcan way, but the crew could always see how he would struggle to incorporate his human thoughts and feelings. Mr. Spock served as the first officer of the U.S.S. Enterprise under two different captains (Christopher Pike and James T. Kirk), until he was promoted to Captain himself and given command of the Enterprise, only to relinquish command to Admiral Kirk in Star Trek II - The Wrath of Khan. Mr. Spock, as played by Leonard Nimoy, appeared in 7 feature films, including as an older version of himself in the 2009 Star Trek "reboot" film.
And of course, he was famous for telling everyone to "Live long and prosper" - and reminding us that the needs of the many outweigh the needs of the few ... or of the one (as Captain Kirk added.)
