Two famous Spocks: (1) Mr. Spock from 《
星际迷航》 (Star Trek) — the half-human, half-Vulcan first officer played by Leonard Nimoy (and Zachary Quinto in the reboots), known for the line "Live long and prosper" (
生生不息,
繁荣昌盛). (2) Benjamin Spock, American pediatrician whose 1946 book 《
婴幼儿保健常识》 (Baby and Child Care) sold over 50 million copies. Context decides which one — Trek references dominate online.
