J.Morwick在讨论化学基本定律时,提出过一个值得体会的命题:所有科学基本定律都是在正和逆两个方向上一样有效。例如,两物体之间既能相互吸引又能互相排斥。描述它们之间的作用力的定律是相同的,只是一个用正号,一个用负号。描述加速或减速、物体吸收能量或发射能量、物体的运动、量子力学,电磁学等等,所有这些“守恒” When J. Morwick discussed the basic laws of chemistry, he put forward a proposition worthy of realization: all the basic laws of science are as effective in both positive and negative directions. For example, two objects can attract and exclude each other. The law that describes the force between them is the same, except that one is a positive sign and the other is a negative sign. Describe acceleration or deceleration, absorption or emission of energy by objects, movement of objects, quantum mechanics, electromagnetics, etc. All of these “conservation”
