A five-part circle story where messy radicals fold into whole-number harmony. Part 1 finds a product rule hiding in regular chords;
Part 2 shows a “broken” seat whose product is always 2;
Parts 3–4 reveal a parent–child pattern that powers every doubling;
Part 5 proves the identity cleanly.
It’s math we don’t invent but discover—symmetry, imagination, and a touch of infinity—told around a round table with friends.
