From
Exhalation: Stories, by Ted Chiang:
Past and future are the same, and we cannot change either, only know them more fully. My journey to the past had changed nothing, but what I had learned had changed everything, and I understood that it could not have been otherwise. If our lives are tales that Allah tells, then we are the audience as well as the players, and it is by living these tales that we receive their lessons."
Nine science fiction stories of all kinds: time travel, entropy, artificial intelligence, alternate universes, free will, robotic childcare, total recall, SETI, and creationism. Most of the stories have been published elsewhere, but they are new to me — the stories anyway, not the ideas. The ideas aren't fresh, but I suppose the value of sci-fi is telling stories to make hard-to-grasp scientific concepts accessible to the non-scientist.
