物理问题不能用纯粹的数学知识来理解

May not Comprehend the Problem on Physics by the Knowledge of Pure Mathematics

数学作为工具用采解决物理问题时,必须受到物理概念和定律的制约,切不可把物理问题“数学化”,只从纯粹的数学角度来解决物理问题。

The mathematics should be restricted by the concepts and laws in physics when it is used to solve the problem on physics. Be sure to may not mathematicsize for the problem on physics, and be sure to may not alse solve the problem on physics only from mathematics angle.
