A constructive approach to the special theory of relativity

TL;DR

This paper uses simple physical models to demonstrate key effects of special relativity, such as length contraction and time dilation, aiming to improve student understanding and clarify the nature of these phenomena.

Contribution

It introduces physical models as educational tools to illustrate relativistic effects, emphasizing the distinction between dynamical and perspectival phenomena.

Findings

Models effectively demonstrate length contraction and time dilation.

Educational approach enhances understanding of special relativity.

Distinguishes between dynamical and perspectival effects.

Abstract

Simple physical models of a measuring rod and of a clock are used to demonstrate the contraction of objects and clock retardation in special relativity. It is argued that the models could help in promoting student understanding of special relativity and in distinguishing between dynamical and purely perspectival effects.
