### ⭐⭐⭐⭐⭐ Dirac, The Master....
*by R***A on February 9, 2022*

This lectures that Dirac gave at Yeshiva University in 1964 deal with the problem of Quantization to systems that have constraints. He had been working all alone for the past years on these matters and was able to gave the correct steps necessary to quantize canonically the theory of General Relativity. I mean from the Hamiltonian point of view, the Hamiltonian of GR is a set of pure constrains so this lectures are basic to understand the quantization of GR. Here he defines Primary and secondary constraints and also First-Class and Second-class constraints and how to deal with them. Primary constraints are the constraints that already come with the theory while secondary are constraints that you can build using the primaries. First class constraints are the ones that commute with themselves and are the ones that generate gauge transformations. Dirac realized that when the system has second-class constraints you need to modify the Poisson brackets in order to get a consistent theory so therefore he introduced the Dirac bracket which has to be used whenever your constraints are second class. Upon his work others came latter and gave a full description of the Hamiltonian of GR and the way to quantize it using Dirac techniques, like Wheeler, Dewitt and Teitelboim. Dirac had a brilliant mind for Physics and this little book contains some of his latter work that should not be looked away, it is a brilliant introduction to the Dirac bracket, also he stablished Dirac quantization on which the constraints are elevated to operators and anhilate the physical states and only a Master can do that.

### ⭐⭐⭐⭐⭐ How-and-why to build [from classical] relativistic quantized field theory via Lagrangian then Hamiltonian mathematics +++
*by K***Y on January 31, 2014*

Dirac's slim work is very general ~ but also very concise and precise and therefore the physical mathematics strategy and methods as presented are so direct as to be ever-valid ~ amounting to a short course on just HOW and WHY to construct [from appropriate classical theory] relativistic Lagrangian-based theory then directly pass into Hamiltonian-based quantum field theory [via Poisson brackets] ~ AND the nuances along the way. I cannot see flaws in Dirac's presentation as given. It seems that for any valid [and especially unified] physical field theory construction ~ it is necessary and sufficient to *pass thru the check-points* just as Dirac has outlined. A very clear and sharp analysis [via short lectures] in a modestly sized and priced slim work with no filler or fluff ~ just physical mathematics most directly derived and explained +++

### ⭐⭐⭐⭐ Dirac’s approach to physics
*by J***. on July 11, 2020*

This book summarizes the four invited lectures PAM Dirac gave at Yeshiva University (New York). They are very sophisticated materials that required strong foundation in graduate level physics. The first chapter is focused on the Hamiltonian Approach to classical mechanics (details found in Goldstein) . Then in Chapter two he describes how to use the Hamilton principles to arrive at quantization of fields (details in Messiah) . The last two chapters describe his attempt to quantize gravity which is the subject of current research in theoretical physics. The content of this book is very illuminating but a significant challenge for beginners. It is Only 67 pages long but the content is very advanced and concise like Dirac’s classic book on principles of quantum mechanics
