QFT ASAP

My popular book Quantum Field Theory, As Simply As Possible will be published by Princeton University Press on January 17, 2023. As a popular book, QFT ASAP is written especially for people who want to learn about quantum field theory but do not have the mathematical background to tackle my textbook Quantum Field Theory in a Nutshell. For some readers, it might serve as a stepping stone towards QFT Nut.
