What does π mean?
Das Pi-Zeichen π ist der sechzehnte Buchstabe des griechischen Alphabets und repräsentiert die fundamentale Kreiszahl, die das Verhältnis des Umfangs eines Kreises zu seinem Durchmesser angibt (ungefähr 3,14159). Ihre systematische mathematische Etablierung verdankt die Konstante vor allem Leonhard Euler.
Als transzendente Zahl ist Pi unverzichtbar in der Geometrie, der Wellenmechanik und der Wahrscheinlichkeitsrechnung. International wird sie am Pi-Tag am 14. März gefeiert. Entdecken Sie auch das Geteiltzeichen, das Plusminuszeichen sowie unsere mathematischen Symbole.
