Hello, It seems like mostly, the masters degree is skipped for those who are seeking a Phd degree (from Bachelor's to Phd directly). I'm in my fourth year as undergraduate, studying physics. I like both math and physics and I really want to master them both. The thing is that my university physics degree (Bachelor) does not offer that much supplements in math and does not focus on it. I will absolutely apply for a Phd in physics "theoretical". But I don't think I am mature enough and satisfied with my math knowledge. So I was thinking of taking a masters degree in mathematics, then apply to a Phd in physics. My decision is based on seeking knowledge. But at the same time it seems like a silly decision! I know most of the math needed in the physics Phd will be learned through it, But the truth is I don't want to be limited with the tools provided for me. Does this decision seems silly for you? What is your opinion?
