Mettenheim on Einstein’s Relativity

I have added “Mettenheim on Einstein’s Relativity – Part I” to “Einstein’s Errors“. The new material draws on the Part I of Christoph von Mettenheim’s Popper versus Einstein: On the Philosophical Foundations of Physics (Tübingen: Mohr Siebeck, 1998). Mettenheim strikes many telling blows against STR. These go to the heart of STR and Einstein’s view of science:

[T[o Einstein the axiomatic method of Euclidean geometry was the method of all science; and the task of the scientist was to find those fundamental truths from which all other statement of science could then be derived by purely logical inference. He explicitly said that the step from geometry to physics was to be achieved by simply adding to the axioms of Euclidean geometry one single further axiom, namely the sentence

Regarding the possibilities of their position solid physical bodies will behave like the bodies of Euclidean geometry.

Popper versus Einstein, p. 30

[T]he theory of relativity as Einstein stated it was a mathematical theory. To him the logical necessity of his theory served as an explanation of its results. He believed that nature itself will observe the rules of logic. His words were that

experience of course remains the sole criterion of the serviceability of a mathematical construction for physics, but the truly creative principle resides in mathematics.
