Ziua pi
Ziua pi este o celebrare anuală a constantei matematice π (pi).[2] Ziua pi este serbată pe 14 martie (3/14 în formatul lună/zi) din moment ce 3, 1 și 4 sunt primele trei cifre importante ale lui π. În 2009 Camera Reprezentanților a Statelor Unite ale Americiia susținut desemnarea unei „zile pi” și celebrarea ei în întreaga lume.[3]
Tot in data de 14 martie 1879, Albert Einstein îşi aniversa ziua de naştere.
