“if, relative to K, K’ is a uniformly moving co-ordinate system devoid of rotation, then natural phenomena run their course with respect to K’ according to exactly the same general laws as with respect to K. This statement is called the Principle of Relativity (in the restricted sense).”

Probable attribution
A source trail connects this quotation to Albert Einstein and Relativity: The Special and the General Theory, but the exact English wording has not been confirmed in a primary text. The attribution is therefore probable rather than definitive.
Likely origin: Relativity: The Special and the General Theory
About this quote
This page records the wording "if, relative to K, K’ is a uniformly moving co-ordinate…," which centers on relative, uniformly, moving. A concrete trail points toward Einstein, but the exact English form remains unconfirmed; the page therefore labels it as attributed to him while preserving its science and wisdom context.
When to use it
- Use "if, relative to K, K’ is a uniformly moving co-ordinate…" in a science discussion, then ask which concrete claim the wording makes.
- Compare its treatment of relative with uniformly in a lesson, essay, or editorial note before drawing a conclusion.
- Before sharing it as Einstein's exact words, display the attribution caveat and follow the evidence link recorded on the page.
