It would be nice to have a version that uses complex numbers and linear algebra instead of spinning arrows. A little bit more math would make it easier to connect with the "grown up" version of the theory.
- toxikitty 11y agoAnthony Zee's book on QFT (http://www.kitp.ucsb.edu/members/PM/zee/QuantumFieldTh.html http://www.kitp.ucsb.edu/members/PM/zee/QuantumFieldTh.html) might be what you're looking for. It starts off with a spring mattress analogy (like the one in the linked article, but with more math) and goes on to more advanced material from there. I remember it requiring little background besides LinAl and multivariable calc.
