Quantum Field Theory, as Simply as Possible Hardcover – 17 Jan. 2023

A very clear introduction to QFT - it has inspired me to try and get to grips with a more advance mathematical treatment - which I think was the objective of this book!

The author seems unable to distinguish between what should be included and what shouldn't. Every few pages there's another page of footnotes, some of which are actually quite important if you want to follow the maths. This makes smooth reading almost impossible.He is terrible at explaining concepts, usually resorting to just using equations (which aren't well laid out, sometimes doing several algebraic manipulations in one step with no explanation as to why those manipulations are being done), and then going "ta-da!".The author tries to make the book "accessible" by adding cutesie names to people in the example scenarios, but is then unable to explain the concepts in the scenarios, but rather just falls back into maths again. Similarly the author uses some "fun" headings or historical anecdotes to try to make the book accessible, but is unable to actually explain his topic well, often just being patronising instead. Here are some quotes from the book:"Even a dull high school student could already see by eyeball that the Galilean transformation t′=t, x′=x+it given earlier ain't gonna cut it"On another page she shows an equation in which a quantity of momentum is equated to a quantity of energy times velocity, with no explanation as to how or why the units of this equation don't add up.(The units of momentum are mass times velocity, not energy times velocity, so this equation is inconsistent with the basic rule of equations that the units of both sides must be equivalent.) Instead of explaining anything about this equation, he just makes this statement afterwards:"Energy corresponds to time, momentum to space, duh."This lack of ability to explain things mixed with insulting snipes towards the reader make for one of the worst books on physics that I've encountered.
