The Vulcan salute is a hand gesture popularized by the 1960s television series Star Trek. It consists of a raised hand with the palm forward and the thumb extended, while the fingers are parted between the middle and ring finger. The gesture was devised by Star Trek actor Leonard Nimoy as a salute for the alien Vulcan species, and is popular within the Science fiction fandom and nerd culture. The blessing phrase "live long and prosper" (written by Theodore Sturgeon) is frequently spoken alongside it.
