The Principles of Quantum Mechanics Paperback – February 9, 2023

WOW! Okay, first off if you do not have an advanced and more advanced degree in math and or physics this book will buffalo you! It is a reprint of Dirac's 1930 explanation of why we need the quantum theory and all of the computations justifying it. It is DEEP. I returned it because it was many fathoms beyond me. But you may give it a hack if you are one of the advanced few who can grasp what even Dirac himself couldn't fully grasp. The print format is lovely since it preserves the original type fonts and page size: it's a trip back in time!

Dirac’s Principles will always be a classic. Einstein took the book wherever he went and when he could not find it he would ask: “Where is my Dirac?”The discovery of the positron is illustrated clearly, later to be confirmed experimentally by Carl Anderson and leading to the 1933 Nobel for Dirac (shared with Schrödinger).Books like this, despite their age, are worth keeping in one’s library, as is John von Neumann’s Mathematical Foundation of Quantum Mechanics (also from the early 1930s, but timeless in its value).

great!!

Meet my expectations? How could it not? It is considered the "Bible" on theTheory. Furthermore, one of the best "popularized" books on Quantum Mechanicsis the pocket sized "The Quantum World" which follows the topics in Dirac's "QuantumMechanics" for laymen by Professor of Mathematical Physics, at Cambridge, J. C.Polkinghorne. He learned the subject attending PAM Dirac's classes from his own book.Professor PAM Dirac ended his days by retiring to a Professor Emeritus chair at FloridaState University (right here) in Tallahassee, FL.

The book was recommended as the best text on QM after all these years, and I wanted to learn QM, and so. far, so good.

Reading this master piece is an challenge to understand the one of the most great mind in Physics, Paul Dirac. With a serious introduction in the mathematical basis, and the following elemental applications, we can swimming in the gorgeous formalism of Quantum Mechanics.

Slow going for me at times, but lucidly written.

I gave it 3 stars only as a warning to those that may get confused, as I was. This book consists in a thorough mathematical treatment of quantum mechanics. Probably, a third of the book is comprised of mathematical equations. I am a non physics scientist interested in quantum theory and the book was way over my head.
