I’m a mathematician who enjoys writing, but I rarely combine the two outside of the workplace. Some folks want to talk about work at breakfast, lunch, dinner and on the weekend. I do not. The separation is necessary for me to remain functional in both places (at work and away from work).
However, sometimes I will bring math into my thought process for fun and entertainment.
Have you ever heard of a book being written on a subject that no one can really agree on a definition? In mathematics, “chaos” is not chaos as you often think of it. As a matter of fact, in mathematics it is easier to define something being chaotic than to define chaos itself.
