For example, while developing special relativity, Albert Einstein was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the Michelson–Morley experiment on Earth's drift through a luminiferous ether.
De exemplu, în timp ce a dezvoltat teoria relativității restrânse, Albert Einstein s-a preocupat de transformările Lorentz care lăsau ecuațiile lui Maxwell invariante, dar nu a fost interesat de experiența Michelson-Morley privind viteza Pământului printr-un eter luminifer ipotetic.
