摘要
质点的意义在牛顿力学和相对论力学中是有差别的。现在看来 ,牛顿力学中质点的意义已远远超过了其最初定义的内涵。相对论力学在揭示时空的本质方面比牛顿力学前进了一大步 ;从牛顿力学到相对论 ,物理学获得了巨大的进步。
The meaning of particle is different between Newton's mechanics and Relativity's mechanics. Frankly speaking, the meaning of particle has far exceeded its original defined intension in Newton's mechanics. Relativity's mechanics goes forward a bigger step than Newton's mechanics in the aspect of revealling the essence of time space. The great progress has been made in physics from Newton's mechanics to Relativity's mechanics.
