Hello everyone, we didn't know where to put it .. so we started a new thread .. if it is useless so delete it ... I try to understand the whole issue of everything here says "create a non-symmetry" I read this forum I follow your successes to you doing well in experiments .. a lot of things I do not think but I try to understand .. my big problem is the language barrier ... the reason why I write here is because we found videos where everything is well illustrated and it starts to make sense .. one I found the vydeo and I would like to share it .. surely some of you know it and you know what it is .. it's more for those who are like me and trying to understand everything ..

Perhaps it is not against the rules we put a link to a video from Youtube .. if so much sorry ..

translated in Google .. perhaps it's understandable to you
