When Paulie’s father dies, all that remains is his coda: a simulated version of himself at the time of his death, usually used to check up on practicalities like his will or life insurance. But Paulie has unfinished business with his father, so he takes the coda home against the advice of hospital employees. Writing with a dry-erase marker on the walls of his father’s simulated hospital room, Paulie attempts to solve two unsolvable problems: a famous mathematical hypothesis that could secure his tenure, and his complicated feelings about his distant relationship with his father.
Like all the best science fiction, the focus of “Proof by Induction” isn’t on the new technology itself, (the coda machine,) but on its effects. In this case, these effects are explored on a micro-scale—one family, one discipline, and one esoteric proof waiting to be solved. The magic of this story is in the little, mundane moments: the charged conversations between Paulie and his wife, and the way Paulie interacts with both his father and his daughter. It’s not uncommon to see stories about stoic mathematicians trying to navigate relationships, but the generational component here makes it uniquely fascinating. It allows the story to be both defiant and hopeful, giving Paulie space to acknowledge his past and pursue his future. For someone who loves details, reading between the lines, and probing the soft, emotional edges of a tale, it’s a very satisfying read.
