I really enjoyed The Death of Vishnu when it came out several years ago. It was a Calvinoesque exploration of a single Bombay apartment dwelling, as refracted through the prism of a dying peasant. But I had no idea that the author, Manil Suri, was actually an academic mathematician:
Q. ARE THERE AREAS WHERE MATH AND WRITING CONVERGE?
A. Actually, there are a few. If you’re writing and plotting the path of your characters, you have to consider the different directions they might go. “If I move something there, what will happen with this other thing?” Or, “How will the characters interact, if they do this or that?”
In mathematics, in place of characters, you have variables or unknowns. If I’m trying to plot a theorem, I try to imagine these variables interacting with each other. The boundary of their interaction is the theorem.
