Pi Day：根據美國軍訓曲調編排的圓周率進行曲

大家Pi日快樂！

非華人朋友包括幾位中學生，根據美國軍訓曲調改編，做了一個《圓周率Pi進行曲》的動漫。

該曲調是美軍操練時唱的，不同軍兵種，不同教官填的詞不同，而且有領唱（教官）和附和（學員），但是曲調一致。

心意讓人很感動，希望大家也喜歡。

It is a March song by a team of teenager robotics students just for fun and led by their coach who learned this tune while in the Army years ago. It is intended to be an easy way to remember 55 digits of Pi, which is essential knowledge for everyone.
