A few unrelated questions around π…
- Why is it true that π=80?
- Why on Earth did we define π as we did, instead of giving a nice symbol to 2π? Life would be much easier… So many less factors 2 in our books… A quadrant would be just π/4, not the nonsensical π/2… Can you see any notational advantage? Read this for more info.
- Do you recognize this sequence: 3, 7, 15, 1, 292, 1, 1, 1, 2, 1, 3, 1, 14, 2, 1, 1, 2, 2, 2, 2, …?
- Why should I have posted this yesterday?
OK, let’s keep it short. And thanks to S.N. Santalla…
Update (March 17) My birthday date appears at position 45,260,128 of π, not counting the initial 3. When was I born? ;) Hint. (Via Pepe Aranda) Moreover: possession of all digits of π makes you infringe all known copyright laws… Do you know why?
