都可以跟貓論聯係起來了

“even the motion itself can not be uniquely defined because neither its temporal nor spatial factors can be uniquely defined. (Young Einstein's daydream of flying with a light beam). Neither the arrow itself can be uniquely defined due to the relativistic effect on the mass of the arrow. But still, each defined path in space-time  (so called "worldline" 世界綫) is precise. It is just not unique.”

其實，俺理解，老芝不過是在提示觀察的角度與結論之間的關係。

而不是尋求一個確定不移的真相。
