<quantum field theory lecture by tobias osborne 2017/lecture 1> mentions that this book is quick and dirty, as one might guess from the title. <Ciro Santilli> thinks he's gonna like this one.

First edition: from 2003, https://www.amazon.com/dp/0691010196[], ISBN-13: 978-0691010199.

Summary:
* page 8: <infinitely many slits thought experiment>


Quantum field theory in a nutshell by Anthony Zee (2010)

Described for example in <quantum field theory lecture by tobias osborne 2017/lecture 1>.

Bibliography review:
* <Quantum Field Theory lecture notes by David Tong (2007)> is the course basis
* <quantum field theory in a nutshell by Anthony Zee (2010)> is a good quick and dirty book to start

Course outline given:
* classical field theory
* quantum scalar field. Covers <bosons>, and is simpler to get intuition about.
* quantum Dirac field. Covers <fermions>
* interacting fields
* <perturbation theory>
* <renormalization>

Non-relativistic <QFT> is a limit of relativistic QFT, and can be used to describe for example <condensed matter physics> systems at very low temperature. But it is still very hard to make accurate measurements even in those experiments.

Defines "relativistic" as: "the <Lagrangian> is symmetric under the <Poincaré group>".

Mentions that "QFT is hard" because (a finite list follows???):
> There are no nontrivial finite-dimensional unitary <representation theory>[representations] of the <Poincaré group>.
But I guess that if you fully understand what that means precisely, QTF won't be too hard for you!

Notably, this is stark contrast with rotation symmetry groups (<special orthogonal group>[SO(3)]) which appears in space rotations present in <non-relativistic quantum mechanics>.
