Paul Dirac: a genius in the history of physics ; Sep 2, Dirac established the most general theory of quantum mechanics

What had emerged was an equation that, in its author's words, "governs most of physics and the whole of chemistry". Dirac was a famously modest man, and was not wont to exaggerate.

When asked what had led him to his formula, Dirac replied simply "I found it beautiful". His equation is indeed a powerful example of the deep and mysterious connection between the language of mathematics and the expressions of the physical world.

The Principles Of Quantum Mechanics

Yet, however much beauty might be indicative of rightness, a physical theory is judged on its predictive power. The Dirac equation did not disappoint. The interpretation of two of its four solutions was clear: they were the two spin states of the electron. But the other two solutions seemed to require particles exactly like electrons, but with a positive charge.

Dirac did not immediately and explicitly state the now-obvious conclusion — out of "pure cowardice", he explained later. But when, in , Carl Anderson confirmed the existence of the positron, Dirac's fame was assured. The translations, and especially those in German and Russian, sold even better. The book quickly established itself as the standard work on quantum mechanics, not only used by students as a textbook but also by many experienced physicists.

Paperback reprints of the fourth edition appeared as late as , and the book is still in demand, eighty years after it was first published. In this essay, I shall be concerned with the first two editions only, those of and The German translation, made by Werner Bloch, was arranged at an early time, as evidenced by a letter from Dirac to his Russian colleague Igor Tamm of January , and it appeared only shortly after the English edition.

Koopman : Dirac on Quantum Mechanics

With good connections to physicists in the Soviet Union, Dirac was also actively involved in bringing out a Russian translation of his book. In the summer of , while attending a conference in Kharkov, he brought the corrected proof sheets with him and handed them over to the Russian theorist Dmitri Ivanenko, whom he had met two years earlier at another conference in Russia Kojevnikov , 36; Gorelik and Frenkel , Edited by Ivanenko and translated by the young Leningrad physicist Matvei Bronstein, the translation appeared in as Printsipy Kvantovoi Mekhaniki.

Although the Russian edition was very successful—it sold three thousand copies in a few months—from an ideological point of view, it was seen as somewhat problematical by Soviet commissars.

Abstract and mostly concerned with foundational matters, Principles had little to say about the many applications of quantum mechanics. To make up for this deficiency, Dirac added, on the request of Ivanenko, an extra chapter in which he covered various approximation methods, such as those developed by Vladimir Fock and Douglas Hartree the Hartree-Fock approximation.

Another way in which the Russian edition differed from the original was that Ivanenko added several appendices and Bronstein a number of footnotes. These additions were made in agreement with Dirac. Moreover, Ivanenko provided a long editorial preface in which he praised the book and compared it to other books on quantum mechanics.

It was edited by Bronstein and translated by C. In theoretical physics in Japan was beginning to develop under the leadership of Yoshio Nishina, who had spent most of the s in Europe on an extended stay. Nishina had visited Dirac in and was his host when he, together with Heisenberg, visited Japan in the summer of After the publication of Principles Nishina thought of producing a Japanese translation, for which he had secured the rights from Dirac and the Oxford University Press.

The fundamental equations of quantum mechanics

The Japanese translation was published in , translated by a team of physicists consisting of Nishina, Tamaki, Minoru Kobayashi, and Sin-Itiro Tomonaga. Although no translation of the first edition appeared, much of its content was included in a book with translations of the lectures that Dirac and Heisenberg had given during their stay in Dalitz , — It was a common feature of the reviews to praise the book for its directness, generality, and completeness.

Some found it to be elegant.
