Thanks!

The reason I asked about it is cause in our class we have a first practice that ask we what previous to Einstein physics thought about some things and then in following practices we must found what after Einstein physics thinks about the same things.

"According to Maxwell the speed of light was the same in every frame of reference (again in absence of matter)." Good point! Thanks DrStupid!

Thanks Nugatory! :-)

Hi people! May be this could be an historical question. Before Einstein, it is suppoused that speed of light in ether is always the same, I´m right? I mean, if observer O is at rest respect ether and observer O´ is moving respect ether and O´ send a photon to O, the speed at which that photon...

Physics allow us to guess the future and this is a very important thing to have greater chances to survive in Darwin´s natural selection terms.

LOL! But I just said "show to", no "teach to" ;-)

Thanks guys. I googled without succes. I´ll see now those you posted. Yes, if I receive a WOW! was enough no matter they do not understand completely the idea. But I need something that makes them really feels there exists something weird, not just my word saying time or lenghts are shorter for...

Thanks. There is no "practical" experiment about relativity? I think something about magnetism it is, but you need to explain first length contraction and there is not good reason to think it as a relativistic thing instead of classical magnetism idea.

Hi! I´m studying to be physics teacher for high school and being in the relativity course, next week we will have the opportunity to show to high school kids something about what relativity is about. Any idea about what to show to them in 10 minutes? Thanks!
