1. The relativity principle is called Galilean relativity. 2. Later, in the 1950s, he enunciated the " Infinite Relativity Principle ": 3. The proposal to combine fractal space-time theory with relativity principles was made by Nottale. 4. What is difficult, however, is to apply this relativity principle to our own lives. 5. However, in Lorentz aether theory the existence of an undetectable aether is assumed and the relativity principle holds. 6. And finally in June and July 1905 he declared the relativity principle a general law of nature, including gravitation. 7. Contrary to Poincar? Lorentz in 1914 considered his own theory as incompatible with the relativity principle and rejected it. 8. More than any linguist, Benjamin Lee Whorf has become associated with what he called the " linguistic relativity principle ". 9. However, if the correctness of the relativity principle is accepted, it is impossible to find this system by experiment. 10. The laws of nature would have to be different in the frames of reference, and the relativity principle would not hold.
