I do not see it from your perpectiva @mohammedfelahi, the classes of quantum mechanics and I present them during my undergraduate studies, ie I saw 2 subjects related to the physics of the particles and I think they are very important to understand in a microscopic way the behavior of the universe . If you do not have a base of quantum mechanics as you could do a postgraduate in this specialty? it would be very complicated to agree ?, then it is essential to have notion about it, in my university in Venezuela specifically the University of Zulia there are excellent teachers in charge of teaching these classes, with much experience and studies in recognized universities worldwide. eye I am not an expert in particle physics but if I have the basic knowledge.
