I'm now graduated as a secondary school educator, having studied a physics minor at university. During that time, I didn't go any further than second year physics, studying basic quantum mechanics, thermodynamics, and special relativity. Much of it I've forgotten, however I keep the basics sharp, having to teach it at school. I'm intrigued by the ideas of particle physics, however I don't think I know enough to fully grasp the concepts behind it. Could anyone provide a path that one might take through university (with a textbook reference if possible) from first year undergrad up to the level required to begin QFT? Thank you!
