摘要

想象一下，我们在火车上玩弄一些机械系统。为什么我们无法检测到列车停驶时与匀速行驶时的行为差异呢？标准答案是，助力是牛顿系统的对称性。在本文中，我将以弹簧为例，论证这一答案是有问题的，因为对称性既不是保持其行为的充分条件，也不是必要条件。我还提出了一个新的答案，根据这个答案，助推器即使不是对称的，也能保持系统行为所依赖的关系特性。

On Symmetries and Springs

Imagine that we are on a train playing with some mechanical systems. Why can’t we detect any differences in their behavior when the train is parked versus when it is moving uniformly? The standard answer is that boosts are symmetries of Newtonian systems. In this paper, I use the case of a spring to argue that this answer is problematic because symmetries are neither sufficient nor necessary for preserving its behavior. I also develop a new answer according to which boosts preserve the relational properties on which the behavior of a system depends, even when they are not symmetries.

期刊介绍： Since its inception in 1934, Philosophy of Science, along with its sponsoring society, the Philosophy of Science Association, has been dedicated to the furthering of studies and free discussion from diverse standpoints in the philosophy of science. The journal contains essays, discussion articles, and book reviews.
