I am getting a bit confused by the difference. I plan on studying Math and Physics and I want to do both of them, so if I am unsure whether to go through a Math Ph.D program or Physics Ph.D program, which one should I pursue? A double major or dual degree? This is the department of Physics in my undergrad, http://www.physics.ubc.ca/undergrad/educate/BEd_BSc_courses.php [Broken] But is that the one I should be looking at? Is "Combined Honors in Mathematics and Physics" the same as a Double Major or a Dual Degree?? I am really confused.
