Collection of nine SF stories: "Life-Line", "The Roads Must Roll", "Blowups Happen", "The Man Who Sold the Moon", "Delilah and the Space-Rigger", "Space Jockey", "Requiem", "The Long Watch", and "Gentlemen, Be Seated". "Life-Line" is Robert A. Heinlein's first published science fiction story (1939), about a man who builds a machine that will predict how long a person will live. It does this by sending a signal along the world line of a person and detecting the echo from the far end.
