感慨中文几何学科的妙味！：-）

几何歌

曾几何时话几何，
不知几何是几何？
几何不知论几何，
几何岂知是几何？
几去何来为几何，
几何到底为几何？
几何未知何必学，
几何学来能几何？
学了几何几何用，
不学几何又几何？
人生在世有几何，
何必苦苦学几何!

Song of geometry

Once upon a time
Geometry is a mystery
In the hand who don't know geometry
Is geometry still geometry?
Time and time again question geometry
Why geometry is geometry?
Is it in vain or useful?
Why study it at all!
What's the point of learning geometry
If it is a complete mystery!
What if geometry learned?
What if it is not explained?
How much time we got in this life?
How wasted in learning the unanswered stuff!
