brainstyle writes "I graduated about a decade ago with a degree in mathematics. I'd like to return to school, but this time I'd like to study physics. Unfortunately I don't have the best options locally, but I have a day job keeping me here, so I'm wondering what would be the best university online studies. I'd like to study at the graduate level, but I don't have many undergraduate physics credits, so bonus points to anywhere that would only require me to get the prerequisites for the area I'm interested in studying (theoretical particle physics). Any thoughts?"
