First of all , I'm glad I found this forum while searching the mathematics of string theory. I want to directly tell you my problem. Well ; I have two ambitions in my life and one is Theoretical Physics. It is a bit more like a passion. In my country , highschool education divides in to three courses. Literature - Middle (half literature half math) and Science (Full science). I am graduated from science course (4 years). Now , actually having a great will to work on Physics , my second ambition as having a Military career is on way. I am a cadet (Military Student - Land forces). But I am educating as a Mechanical Engineer (having all courses universities have as Mechanical engineering). When I graduate I'll have also Mech. Eng. diploma. Enough storyline :) Here is the question. I have lots of time. My school is 4 years like all universities. And while this 4 years education , I want to educate my self just like a Physics student do. I'll have the all courses they had for their University education. I "do not" care about having a Physics degree officially. Did Fermat had a Mathematics PhD? I give no care for being a Professor a day or not. Only I care is understanding the universe. This is my humanitarian responsibilty to. If I can make a real contribute to our understanding about universe that'll be my great honor and pleasure. I am going to buy all the books they buy. Learn all the lessons they do. If I can't understand something , I'll ask here or go to a University for it. Why I write this ? Well , sometimes I do need some courage. That might look really hard to achieve but when looking from the both sides ; Deterministic : If I meant to success , I will success. Possiblistic : If the Universe is a possiblity universe , then success is a possiblity. If it is , It'll worth trying. I can understand Physics by reading mostly. And as Einstein said ; I have to do If I can do it. I have to do it as best as I can. This is my sacred human responsibilty. Less is unforgivable.
