论文摘要
我们概述了相对论力学的两个主题：（i）允许世界线的集合，以及（ii）动力学控制点粒子的相对论定律的起源。我们表明：（i）粒子和田地的经典理论中允许的世界界线是非常简单的几何对象，而不是相关的三维轨迹，（ii）牛顿的第二定律既不需要修改也不需要概括，它只能平稳地嵌入到Minkowski Spacement的四维几何学上，以产生动力学律，以使其具有元素的范围。
We outline two subjects of relativistic mechanics: (i) the set of allowable world lines, and (ii) the origin of the relativistic law of dynamics governing point particles. We show that: (i) allowable world lines in the classical theory of particles and fields are quite simple geometric objects as opposed to their associated three-dimensional trajectories, and (ii) Newton's second law requires neither modification nor generalization, it should be only smoothly embedded in the four-dimensional geometry of Minkowski spacetime to yield the dynamical law for relativistic particles.
