A second-year physics PhD student is contemplating a switch to computer science (CS) due to concerns about the job market in physics. The discussion highlights that some physics PhDs have successfully transitioned to roles like quants on Wall Street, leveraging their skills in computer simulation and modeling. The student has programming experience in C++, Fortran, and Matlab but lacks formal CS education. They express interest in machine learning and data mining, noting that many in these fields come from physics backgrounds, particularly in bioinformatics. There is a debate on whether to switch entirely to CS or to integrate CS with their ongoing PhD studies. The consensus suggests that while some physics PhDs find opportunities in finance and CS, the path often involves postdoctoral positions. Ultimately, the recommendation leans towards making the switch to CS, citing better job availability in the field.
