Famed actor and science-fiction icon Leonard Nimoy passed away today at the age of 83. Known primarily for his role as Spock in the popular television series Star Trek, Nimoy also did many other media ventures, including sitting in the director’s chair for the 1987 classic Three Men and a Baby. While I’m not a Star Trek fan/Trekkie, I do know that he’s an important figure in science-fiction popular culture. Surprisingly, his best “cameo” in television’s #1 comedy The Big Bang Theory was in name/DNA only.

Sheldon’s reaction encapsulates how many people viewed Mr. Nimoy.
