How would you define your own polymathic process?
For example, around a year ago, I developed an interest in physics - something I haven't studied since I was in school almost 40 years ago. Now I'm building entire mathematical and mechanical frameworks from purely conceptual data (side effect of my aphantasia).
What I find is that the deeper I go into a subject, the more connections I discover to literally EVERY subject I have ever learned. In other words, I find it almost impossible to compartmentalize, and so everything I learn ends up as part of the same "continuum".
Does that make sense? And how does it compare to your own experience.
