Spock. The most iconic character in one of the most iconic TV shows in history. Star Treks themes of exploration and adventure have not only inspired generations of science fiction but also many of the scientists that currently advance our understanding of the universe.
Whilst I can't claim to be a trekker myself, Star Trek has been on my radar for as long as I can remember with the original series being one of the first TV shows I remember watching and the Undiscovered Country being the fist film I saw at the cinema without my parents.
And as much as I enjoy it, Leonard Nimoy's appearance as Mr. Spock lent a few moments of class the rebooted series, that will sadly never be repeated.
