Six Textbook Mistakes in Quantum Field Theory

[Muu9]

TL;DR

"This article discusses incorrect statements appearing in textbooks on quantum field theory (QFT); some of these mistakes also appear in the research literature. The focus is not on errors made by an individual author, but on conceptual muddledness that is widespread in introductory textbooks."

We should have more articles like these. Mistakes 2, 5 and 6 can be really misleading, however I was expecting more flagrant errors.
I would argue that mistake 1 is nit-picking and not truly a source of misconception (also the author does not provide a better picture for relativistic quantum mechanics). Mistake 3 is actually just a (good) suggestion.

Personally, I need to look more into mistake 4.
