In deep space, a physicist tries to cope with his isolation.
"He read several classic novels and philosophical texts to pass the next few days and exercised on the stringy, wiry contraption collapsed into one wall. The long hibernation had melted the muscle from him and congealed the quick currents of his mind, but he had to be alert, intelligent, and at his peak physical condition when he arrived. He was supposed to be disciplined. He was not supposed to replay his wife’s voice over and over, with longing and anxiousness. So he selected his parents’ recordings."
