Hi , I am interested in physics and mathematics however i am not a physics college student.I'm however studying medicine although the only subjects that i loved in high school are physics and mathematics . I entered the medical college because in my country , unless you are a doctor , you will not find a job . graduates of the college of science in my country almost work as taxi drivers . I have just finished the book fundamentals of modern cosmology which i found very interesting and that caused me to like physics . I want to read farther in physics as i will be able to understand the laws by which this universe operates . I want to know about the fields of the mathematics that should be known by me in order to understand most of the fields of physics . What should i do if i want to study physics . and what is a physics minor?
