Physics Starting my PhD in cosmology -- question about my career prospects
Hello all,Next year, January I will start my PhD in Cosmology. Salary is fair and I don't have to pay the tuition fee. I always loved the idea of doing a thesis about Cosmology. My master's degree was about computational physics where I had to learn how to program in C/C++, Fortran, Matlab...- arierreF
