Burdened by repressed guilt and afflicted with a self-imposed incapacity to assign meaning to interpersonal relationships, a neurotic and introverted physics professor launches an absurdly rational scientific quest: to either prove by her life or disprove by her death a concurrently fantastic and infinitely alluring theory--quantum immortality. But it is a theory that ironically can only be proved by Sophie undergoing repeated experiments that in all probability will result in her death. For in each one of these experiments, there is a 50% chance she will live and a 50% chance she will die. Her continual Russian Roulette gambles are what is known as the thought experiment of Quantum Suicide.—Anonymous
