Hi again, I look forward to your next one. They all give me some information but I don't necessarily want to do the same. You want to calculate on the quarks and you talked about the standard model. I believe that is a job and a half. I just looked at another video about the same subject and there was shown some formula's and calculations that was told would probably not even be thought in university. It was page by page of just one formula. I like to know some thing about that it exists but not how to make them so to speak. Also I understand that only a few are stable anyway. The rest break down to the stable ones and expel electrons and neutrino's. The latter tells me that they are all build up of smaller parts anyway. That is where my interest is more directed.
