Read full description of the books Lectures on Quantum Mechanics (Dover Books on Physics):This book is "hard" because it is too terse in a real sense. With only 90 pages or so Dirac managed to perform quantization via Hamiltonian formalism. It is to be understood that the readers are experts in the field or researchers well acquainted with some aspects of quantum field theory already. This is further supported by the fact that in final chapter Dirac seems to assume reader has heard of Born-Infeld electrodynamics. I am unfortunately only fourth-year undergraduate with somewhat ill-developed fundamentals.
However, this book can be quite a good eye-opener on some fundamental concepts. In chapter 1 and 2, his discussion on classical Hamiltonian and constraint equations make it clear what constraint equations mean in physics and how it translates to e.g. gauge fixing, Lagrange multiplier-type of constraint enforcement, among others. While classification of constraints into 4 types (primary, secondary, first class, second class) can be confusing, the discussion on constraint equations in Hamiltonian formalism is illuminating - since even in modern understanding of general relativity (and electrodynamics), the constraint equations and evolution equations are exactly what the ADM decomposition and Maxwell's equations are.
Although solid insights are probably manifest only after second or third reading, it is still worth reading despite the likelihood to be out of date compared to present-day (2016) developments in quantum field theory. This is especially the case when the book is only 90 (small-sized) pages thick.
