Imperial 8vo (25,4:18,2 cm). 14 pages. Letterpress on machine paper, in original publisher’s brochure on orange stock with black title printing.

First offprint in the original wrappers, of this important seminal paper by Einstein related to the Quantum Theory, of particular rarity.

Content, Edition: 2nd of two seminal papers, in which Einstein creates the theory of identical particles in quantum mechanics. In 1924, Satyendra Nath Bose derived Planck's law of black-body radiation from a modification of coarse-grained counting of phase space. Einstein shows that this modification is equivalent to assuming that photons are rigorously identical, leading to the concept of coherent states. Einstein also extends Bose's formalism to material particles (bosons), predicting that they condense at sufficiently low temperatures, as verified experimentally.

Condition: Mint.
