Albert Einstein - Zur Quantentheorie des idealen Gases - 1925

Albert Einstein – On the Quantum Theory of the Ideal Gas

Special reprint from the Proceedings of the Prussian Academy of Sciences, Physical-Mathematical Class, January 29, 1925. Berlin, Verlag der Akademie / Walter de Gruyter, 1925.

8 pages (pp. 18–25). Original orange-covered edition.
A very well-preserved copy of this historically significant work: Einstein's third and decisive treatise on the quantum statistics of ideal gases, in which he first predicts Bose–Einstein condensation – the theoretical cornerstone for the fifth state of matter (experimentally confirmed in 1995).
Rare original special print offered on the market (not a later reprint)
