please,Help me to choose my career. Need URGENT help for my Physics career.Plz Help me to choose. Hi Physics forum, I am kiran from India, studying undergraduate physics final year. I am going to study in UK. still I am searching for good university. I am going to complete my bachelor's degree in 2010 march.I want to do M.sci in Physics. What is difference between Mathematical physics and Theoretical Physics ? what is mathematics and theoretical physics course? I want to study theoretical physics (I am good at math !). I want to study all the fields in Physics except medical physics,geo-physics (I love some facts in it). If I take -Nuclear Physics I miss Astrophysics. -If I take one I miss other .... -If I take quantum. I miss cosmology and others. I love astronomy too !!! I am ready to spend my whole life for physics like a soldier in a battle sacrifices his life. I gave up every enjoyment in life. I don't need it.cos I enjoy science. I am going to be celibate. My only friend in my life is Physics,math and all science stuff. I am intellectual (ever since I was Kid). I never had friends. never had good teacher other than Nature her self and great persons from history. I Love Nature and her laws. so, Which course I need to take in physics ? I love string theory too. Quantum mechanics(esp. cats in it) all ! Even Optics ... Light,heat,electricity and magnetism,modern Physics all. My girl friend physics attracts me in every dimension. math helps me to measure her beauty. I am living today to satisfy my curiosity. My desire to know the unknown I love chemistry too.. I don't care even if I am lonely. I gave up everything. My work speaks, What I can do ! I believe in my abilities. I will never give up even if I fail. What do I need to take ? Which course in physics ? I am thinking of theoretical physics. guessing it would cover everything in physics. I don't need any thing in life other than Physics math and science stuff.
