Hello everyone, my name is Silkia and I'm a new member. I am a pediatrician but as with Alejandro in another thread my real love has always been physics. In three occasions I had decided that this was my career choice but long "stories" short, I ended up in medical school. As an undergraduate I took all the math courses required for a physics degree however this was a long time ago. I have finally decided to really pursue physics but at this time I will mostly be self taught I would love to go back to college and my ultimate goal is to earn a PhD but I need to figure out how to do that with having a day job ( might need to start working night shifts). I would appreciate any advice and suggestions for textbooks for math and classical mechanics. I might as well review everything to avoid any gaps in knowledge. I am currently listening to online MIT Quantum mechanics lectures and I am enjoying every single second but I need to go back and review my previous knowledge. Thanks in advance for any help that you can provide.
