„... introduce the auxiliary concept of first-signal... defined as the fastest message carrier between any two points in space. We now send a first-signal from P, calling the event of departure E1... The event of its arrival at P' is called E'. Simultaneously with the arrival of this signal, another first signal is sent from P'. The arrival of this signal at P is the event E2.... the time interval between E1 and E2 is coordinated to the event E', [E1 is earlier than E' and E2 is later than E'] and every event of this time interval except for the endpoints is inderterminate as to the time order relative to E'.“

„The first time you blow someone away is not an insignificant event. That said, there are some assholes in the world that just need to be shot.“

—  James Mattis 26th and current United States Secretary of Defense; United States Marine Corps general 1950
Context: The first time you blow someone away is not an insignificant event. That said, there are some assholes in the world that just need to be shot. There are hunters and there are victims. By your discipline, cunning, obedience and alertness, you will decide if you are a hunter or a victim. It’s really a hell of a lot of fun. You’re gonna have a blast out here! Addressing a gathering of 200 Marines in al Asad, as quoted in the Armed Forces Journal article "Fiasco", published on August 1, 2006. http://www.armedforcesjournal.com/fiasco/
