Thanks!

Hi, this is my modified post since I've been told that I have to use certain format. I hope this is good now. Homework Statement Copper (conductor) sphere of radious R with an spheric bubble inside placed at distance c from the center, with radius b. The metalic sphere has charge Q.Homework...

I will try to use this math symbols the best I can (first time using them on a post :) ). I might be wrong, but what I think is that I should have the charge Q distributed in both surfaces so I have the denisty of charge ρ= Q/ (4πR^2+4πb^2). Then I can use Gauss and have the electric field...

Hi, I need some help with this homework from my Electromagnetism course. I hope this is the correct place to post this. (Please excuse any potential english mistake I made trying to translate this). Problem 1: Copper (conductor) sphere of radious R with an spheric bubble inside placed at...

Yes, that was exactly my confussion, so observation stands for instant measure of something that's happening within our frame. I will indeed serch for the "relativity of simultaneity" concept. Thanks for the answer!

What happens if inside the train we build another track that goes in circles, and we repeat this process over and over, would that mean that theoretically we can we can travel all the age of the unvierse in less than a second or a infinitesimal amount of time?

I apologgies for my rookieness, its just that I'm relavitely new to physics and I'm very exited about learning. I realize now that as long as the relative system is not moving at some speed, the parameters (vectors) don't change, and observation means absolute measure within the relative system...

Thanks for the answer, I'm sorry If I don't understand the correct words well because of my lack of knowledge, I'm triying to use words that can express my question (also my english is not very good :P). Yes with bidimensional observation I mean what an object is observing, I use that because...

That in a relative system our observed parameters are different vs another relative system. For example, for observation we can only tell that the sun is a point moving on a plane, it's impossible for us to tell how far the sun is without absolute information.

Hello! I have some confusions about this topic, I'm a physics newbie so my question may have no sense, please have mercy ;). It's supossed that relativity only considers observation as valid "what we see", but observation it's independent of what we know (we can't tell how distant we are from...

Thanks. Yes, I realize that I'm probably wrong. Can I post it in the form of a question? is that I have some confusion and doubts about the classic clock with beam of light example.

Great answer. Thank you!

I'm sorry for the question and maybe it's the wrong place at the forum to ask, but I need to know, what I have to do If I find a flaw in the General Relativity theory? Write a paper? what are the steps? Thanks.
