Hi all. I'll choose what subject(s) to study in university in November this year. I am thinking of choosing physics and maths(double majors) and I want to know more about what it is like when you are studying these 2 subjects? Of course I want to get PhD and do researches but I'm not sure whether I have potential or not. Do you need to be exceptionally intelligent in order to get a PhD ? What obstacals or difficults did(do) you meet when you were(are) an undergraduate? I am interested in math/physics now but I'm afraid I'll lose interest after a few years. Besides phy/math, I'm thinking of entering a medical school, which is a totally different stream in science but the future seems more promising. I'm not studying biology now but I'm studying chemistry. I like helping others and to be a doctor can help lots of people for sure. Both to be a surgeon and to get a PhD in math/physics are my dreams. I would like to know is it possible for a person who is a surgeon while is doing researches on physcis or maths, like part time mathematician or physicst ? I'm thinking of studying engineering too but I don't know much about it. I'm studing pure math and I can apply to enginnering dept. Is engineering fun ? I still have about 5 months to think of this problem seriously. I know there are lots of people who are studying/ have studied the subjects I mentioned. Any suggestions ?
