Copenhagen: Bianco Luno, 1918-1922. A fine set of this major work: It was in this fundamental paper that Bohr first gave a clear formulation of, and fully utilized, his 'correspondence principle'. Besides his derivation of the Balmer formula (1913), this is by many considered to be Bohr's greatest contribution to..... More
Item #2257

Copenhagen: IIe Congrès International de la Lumière, 1932. First edition of this famous lecture, which marks Bohr’s first detailed attempt to apply concepts arising from quantum mechanics (particularly complementarity) to areas outside physics. “Here, for the first time, Bohr raised a question that was to preoccupy him, off and on.....

[London: Harrison and Sons], 1910. Presentation offprint, inscribed in Bohr’s hand to the chemist Einar Biilmann, of the ‘Second Royal Society Paper’ – what Bohr “learned by working in this field may have been a help to him when, more than a quarter of a century later, he showed that..... More
Item #3505

London: Macmillan, 1928. A fine copy in original wrappers of this fundamental paper introducing Bohr’s statement of his ‘complementarity’ principle, the basis of what became known as the ‘Copenhagen interpretation’ of quantum mechanics. “From the epistemological point of view, the discovery of the new type of logical relationship that complementarity.....

Paris: Gauthier-Villars, 1926; 1928. First edition of these expanded presentations of the ideas in de Broglie’s epoch-making doctoral thesis on the quantum theory, which, Einstein said, “lifted a corner of the great veil” (Isaacson, Einstein: His Life and Universe, p. 327). In that work he developed the startling and revolutionary..... More

London: Harrison & Sons for the Royal Society, 1930. First edition in original printed wrappers of Dirac’s prediction of anti-matter – although he did not accept it as such until a year later (see below) – and the advent of the dynamical view of the vacuum which was fundamental to..... More
Item #3519

Lancaster, PA: American Physical Society, 1935. First edition, very rare offprint, of the famous ‘EPR paper’, one of the most discussed and debated papers of modern physics, and the foundation for the new fields of quantum computing and cryptography. “In the May 15, 1935 issue of Physical Review Albert Einstein.....

Vancouver: [np], 1975. A detailed draft for a talk given to the Canadian Association of Physics Students, in Vancouver, on the contemporary state of subatomic particle physics, its current difficulties and possible future developments. Although a ‘popular’ talk, it is pitched at a high level, appropriate to postgraduate students in physics..... More

New York: W. W. Norton & Company, 1985. First edition, first printing, and a fine copy in a bright dust jacket, signed by Feynman and from the library of a second Nobel Prize winner, Edwin P. McMillan. Signed copies of this first printing are rare: Feynman was notorious for refusing..... More
Item #4459

Berlin: Springer, 1926. First edition of Gordon’s account of the ‘Klein-Gordon equation’ (‘KG equation’ in what follows), the first attempt at unifying wave mechanics with special relativity. The KG equation was discovered by several authors independently, the first being the Swedish physicist Oskar Klein, although the equation appeared only incidentally..... More
