闵可夫斯基与狭义相对论：他的时空几何能解释空间收缩吗？
Minkowski and Special Relativity: Does His Spacetime Geometry Explain Space Contraction?
摘要：
一个多世纪以来，闵可夫斯基时空一直主导着狭义相对论中关于空间收缩和时间膨胀的讨论。布朗和普利对闵可夫斯基的假设以及他所假设的时空对运动物体的影响都提出了质疑。但是，尽管他们拒绝闵可夫斯基，布朗和普利并没有填补速度与空间收缩和时间膨胀之间缺失的因果关系。为了提供物体和观察者在相对运动中的这种因果关系，我们应该关注能量差而不是速度差。当不同的惯性观察者以不同的相对速度测量同一个杆（或钟）时，每个观察者记录的物体的动能的量不同。遵循这一结果，可以对相对论性的空间收缩和时间膨胀有新的理解。
英文摘要：
For over a century Minkowskian spacetime has dominated discussions of space contraction and time dilation within special relativity. Brown and Pooley have called into question both the assumptions of Minkowski and the effects his presumed spacetime has upon objects in motion. But while they reject Minkowski, Brown and Pooley do not fill in the missing causal connection between velocity and space contraction and time dilation. To supply this causal connection between object and observer in relative motion we should be focusing on energy difference rather than velocity difference. When different inertial observers at different relative velocities measure the same rod (or clock), each observer registers a different amount of kinetic energy for the object. Following the consequences of this permits a new understanding of relativistic space contraction and time dilation.
