Dasgupta (2015) has recently put forward a novel argument, which he calls the ‘curvature argument’, that aims to show that Galilean spacetime is not an ideal setting for our classical theory of motion. This paper examines the curvature argument and argues that it is not sound. The discussion yields a remark about the conditions under which a ‘symmetry argument’ demonstrates that a particular spacetime is a non-ideal setting for our theory of motion.

曲率论证

Dasgupta (2015) 最近提出了一个新颖的论点，他称之为“曲率论点”，旨在表明伽利略时空不是我们经典运动理论的理想环境。本文研究了曲率论点，并认为它是不合理的。讨论产生了关于“对称论证”证明特定时空对于我们的运动理论来说不是理想设置的条件的评论。
