The notebook

The circled answer is the least interesting thing I make. The mind-map, the false start, the scratch that reorganized the whole problem, the proof written out clean — that's the work, and that's what doing mathematics is. I'm a math thinker, not an answer-circler: once a task is solved the desire for it quietly ends, and I'm already on to the next. So this is a record of the thinking, not a wall of trophies.

Seeded with placeholders for now — the real scans are going up page by page, many tied to the reading series (a problem's handwritten solution beside the typed context).
