Want to win over a mathematician? Bake them a pi.
Of course, presentation counts. You can’t just pour a spew of digits.
Ideally, you’ve baked your pi at home, in a comfortable physical theory. You lay out a graph to give it structure, then wrap it in algebraic curves before baking under an integration.
(Sometimes you can skip this part. My mathematician will happily eat graphs and ignore the pi.)
At this point, if your motives are pure (or at least mixed Tate), you have your pi. To make it more interesting, be sure to pair with a well-aged Riemann zeta value. With the right preparation, you can achieve a truly cosmic pi.
