Re: special relativity



Consider that the measured speed of a SOUND wave is dependent on the
observer's speed (relative to the medium).

Subject: special relativity


| Most textbooks and teachers (at least all that I have seen or known)
introduce special relativity by introducing two postulates:
|
| 1) The laws of physics are the same in all reference frames
|
| 2) The speed of light is independent of the speed of the source and the
observer.
|
| I have always thought that these are redundant. Isn't 2) implied in 1)?
