"One of the great difficulties of Dirac's wave equation was from the very beginning, the existance of states of negative energy. The jump from a normal state to such an abnormal state isnot forbidden by any selection rule. Thus, one would expect all electrons to jump into these negative states, contary to experience. The solution of this riddel was given by Dirac'smarvellous theory of holes. Dirac supposed all states of negative energy to be occupied except perhaps a few of small velocity. 'We shall have but an infinite number of electrons in negative-energy states.but if their distribution is exacltly uniform we should expect them to be completely unobseercvable. Only the small departures from uniformity, brought about by some of the negative-energy states being unoccupied, can we hope to obeserve'. He next considers vacant states of 'holes'" (B.L. van der Waerden).

"In quantum mechanics the state of a quantum system is usually represented by a function of real variables, the domains of which are the eigenvalues of certain observables. In 1937, Dirac suggested that the condition of realness be dropped and that the variables be considered as complex quantities so that the representatives of dynamical variables could be worked out with the powerful mathematical machinery belonging to the theory of complex functions. If dynamical variables are treated as complex quantities, they can no longer be associated with physical observables in the usual sense. Dirac admitted this loss of physical understanding but did not regard the increased level of abstraction as a disadvantage . . . With his new method Dirac showed how the hydrogen atom could be treated in an elegant way, but he did not derive new physical results" (Kragh, Dirac: A Scientific Biography, pp. 282-283).

In the spring of 1928 Heisenberg, who was then teaching at the University of Leipzig, invited Dirac to Leipzig to give a lecture on the relativistic theory of the electron during "University Week" (18 - 23 June). This lecture marked Dirac's first public presentation of his theory. At the end of the lecture Dirac "addressed explicitly a fundamental difficulty of the relativistic wave equations for charged particles . . . Evidently, the negative energy-value problem appeared in Dirac's theory. Though Pauli hoped to solve the difficulty by a noncombination rule, Dirac admitted in Leipzig quite frankly, â In general, this is not possible . . . It appears that this difficulty can be removed only by a fundamental change in our current ideas, and is connected with the distinction between past and future'" (Mehra & Rechenberg, The Historical Development of Quantum Theory, 6, p. 306). Dirac gave his lecture in English; it was later translated into German and published in a collected edition of the 1928 Leipzig lectures edited by H. Falkenhagen. .

First Editions, Offprint Issues. In the fall of 1934 Dirac accepted an appointment at Princeton's Institute for Advanced Study, where he spent two terms attached to the School of Mathematics. "Dirac's stay at Princeton resulted in two papers, both of which were published in the Annals of Mathematics, signifying that they were contributions to mathematical physics . . . Dirac examined two geometries, de Sitter space and conformal space . . .These more general spaces had previously been applied to general relativity and electromagnetism, and Dirac now showed that the fundamental questions of quantum mechanics could also be formulated in de Sitter space and conformal space" (Kragh, Dirac: A Scientific Biography, p 168). De Sitter space, named for astronomer Willem de Sitter, serves as one of the simplest mathematical models of the universe consistent with the universe's accelerating expansion; conformal geometry, which is concerned with angles rather than distances, deals with the set of angle-preserving transformations in conformal space. .

Black cloth backstrip pasted on to spine, otherwise a fine copy (without institutional stamps). [Dirac's paper:]Pp 610-624. [Entire issue:] Pp. 541-730, (2), XXXVI, X + 6 plates. First printing of Dirac's landmark paper in which he unified quantum mechanics and relativity and implied the existence of antimatter now known as the Dirac Equation" one of the great triumphs of theoretical physics which brought him on a par with the works of Newton, Maxwell, and Einstein before him. In 1933 he was awarded the Nobel Price in Physics "for the discovery of new productive forms of atomic theory", a direct consequence of the present paper. "[The Dirac Equations] ranks among the highest achievements of twentieth-century science" (Pais, Inward Bound, p. 290)."In the Dirac equation not only quantum mechanics and the special theory of relativity were married, but also the spin of the electron is contained in it without any ad hoc assumption. But the equation not just beautifully described known phenomena, it did more. It predicted the existence of electrons with negative energy. This was at first held to be a severe problem of the theory but was finally understood as great progress, because negative-energy electrons could be interpreted as hitherto unknown particles. Thus, the existence of new particles was predicted which had all properties of the electron except for the electric charge. These particles were indeed found four years after the equation. Dirac is often quoted to have said that his equation 'contains most of physics and all of chemistry'." (Brandt, The Harvest of a Century)."Even with the many successful applications of quantum mechanics to spectroscopy and other areas of physics, the theory was not without problems. There was, for example, the question of the relationship between relativity and quantum mechanics. If quantum mechanics was really a fundamental theory of the microcosmos, it ought to be consistent with the fundamental theory of macroscopic bodies, the (special) theory of relativity. Yet it was obvious from the very beginning that this was not the case. It was not too difficult to construct a relativistic quantum wave equation, such as Schrödinger had already done privately and as Oskar Klein, Walter Gordon, and several other physicists did in 1926-27. Unfortunately, this equation, known as the Klein-Gordon equation, did not result in the correct fine structure of hydrogen and it proved impossible to combine it with the spin theory that Pauli had proposed in 1927. The solution appeared in January 1928, when Dirac published his classical paper on 'The Quantum Theory of the Electron', which included a relativistic wave equation that automatically incorporated the correct spin. Dirac's equation was of the same general form as Schrödinger's equation [.] and included matrices with four rows and four columns" correspondingly the Dirac wave function had four components. Most remarkably, without introducing the spinning electron in advance, the equation contained the correct spin. In a certain, unhistorical sense, had spin not been discovered empirically, it would have turned up deductively from Dirac's theory. The new theory was quickly accepted when it turned out that the Dirac eigenvalue equation for a hydrogen atom resulted in exactly the same energy equation that Sommerfeld had derived in 1916. Dirac's relativistic wave equation marked the end of the pioneering and heroic phase of quantum mechanics, and also marked the beginning of a new phase" (Kragh, Quantum Generations, p. 167).

First Edition, Offprint Issue. "[Dirac's] paper of 1938 was an important contribution to electron theory and is still considered to be a classic" (Kragh, Dirac: A Scientific Biography, p. 189). In an attempt to resolve the issues with infinities that plagued quantum electrodynamics in the 1930s, Dirac set out to come up with a better classical theory of the electron that could then be quantized. In the present paper he created a finite theory of point electrons that yielded the "Lorentz-Dirac" equation (also known as the "Abraham-Lorentz-Dirac equation of motion"), which "was exact and involved neither infinities nor structure-dependent terms" (Kragh, p. 194). Unfortunately, Dirac's theory, "in spite of its formal beauty, . . . involved unphysical â runaway' solutions (spontaneously accelerating electrons) that could be eliminated (at the classical level) only at the price of making supraluminal [faster than the speed of light] signals possible" (Dictionary of Scientific Biography). Dirac continued to work on classical electron theories until the 1960s. This copy is from the library of Dutch physicist H. A. Kramers, one of the main architects, together with Pauli, Heisenberg and Schrödinger, of quantum mechanics. Kramers annotated this copy with a number of notes and equations in pencil, which can be found on pp. 155 and pp. 164-168. .

Original printed wrappers, slightly sunned. Very good. Sheet with ink notations and pencil equations laid in. First Edition, Offprint Issue. The first of Dirac's papers to attract widespread attention from his fellow physicists. In the first part of 1926 Dirac had developed his own algebra for quantum mechanics, which he called q-number algebra. In the present paper he applied q-number algebra to Compton scattering, the scattering of a photon by a charged particle such as an electron, which provided demonstrable proof of the particle nature of electromagnetic radiation (this scattering phenomenon was discovered in 1923 by American physicist Arthur H. Compton, who would receive a Nobel Prize for this achievement). Dirac showed that Compton scattering followed from his theory. "For the change in wavelength of the radiation, he managed to reproduce Compton's formula, which expresses conservation of energy and momentum. As to the intensity of the scattered radiation, he obtained a result very close to that found by Compton in 1923 but not quite identical with it . . . Dirac's treatment of the Compton effect was recognized to be a work of prime importance. In the period 1926-9, the paper was cited at least 33 times and thus became the first of his papers to have a considerable impact on the physics community" (Kragh, Dirac: A Scientific Biography, p. 28). .

First Editions, Offprint Issues of Dirac's papers introducing his own approach to quantum electrodynamics, which inspired Schwinger and Tomonaga's Nobel Prize-winning work on the development of modern QED in the 1940s. Dirac founded quantum electrodynamics in 1927 with his landmark paper, "The quantum theory of the emission and absorption of radiation," but after this paper he did not return to the subject of QED until 1932, when he published "Relativistic quantum mechanics" (no. [1] above). In this paper Dirac explicitly rejected Heisenberg and Pauli's approach to QED set forth in their two-part joint paper of 1929-30, replacing it with his own formulation, which he believed provided a better foundation for quantum field theory. Dirac's alternative approach to QED was soon shown to be mathematically equivalent to the Heisenberg-Pauli theory; however, Dirac felt that his version was superior from a conceptual point of view and continued to develop it in "On quantum electrodynamics" (no. [2] above), co-authored with Russian physicists Vladimir Fock and Boris Podolsky. The formal innovations outlined in Dirac's two papers "proved to be important for the later development of quantum electrodynamics. When the emergence of modern renormalization techniques finally provided a breakthrough for the theory in 1947-8, Dirac's papers served as an important source of inspiration. Julian Schwinger, one of the architects of the new theory, was inspired by the Dirac-Podolsky-Fock formulation; he developed it greatly and also coined the term â interaction representation.' Sin-Itoro Tomonaga, another of the fathers of modern quantum electrodynamics, was fascinated by Dirac's 1932 paper, which â attracted my interest because of the novelty of its philosophy and the beauty of its form. The long and troublesome road toward renormalization thus took its start in aspects of Dirac's work" (Kragh, p. 138). Kragh, Dirac: A Scientific Biography. .
