(Stockholm, Beijer), 1885. 4to. As extracted from "Acta Mathematica, 21. Band]. No backstrip. Fine and clean. Pp. 259-380. First printing of Poincaré's famous paper in which he proved that a rotating fluid such as a star changed its shape from a sphere to an ellipsoid to a pear-shape before breaking into two unequal portions. "This work, which contained the discovery of new, pear-shaped figures of equilibrium, aroused considerable attention because of its important implications for cosmogony in relation to the evolution of binary stars and other celestial bodies." (The Princeton Companion to Mathematics, P. 786)Another famous paper of Poincaré in celestial mechanics is the one he wrote in 1885 on the shape of a rotating fluid mass submitted only to the forces of gravitation. Maclaurin had found as possible shapes some ellipsoids of revolution to which Jacobi had added other types of ellipsoids with unequal axes, and P. G. Tait and W. Thomson some annular shapes. By a penetrating analysis of the problem, Poincaré showed that still other "pyriform" shapes existed. One of the features of his interesting argument is that, apparently for the first time, he was confronted with the problem of minimizing a quadratic form in "infinitely" many variables." (DSB)

Titlepages stamped in blind at foot "The Chemists Club Library". First appearance of these importent papers, the investigations recorded here gave an essentuial contribution to the development of the first atomic bomb and to the advancement of nuclear physics. In collaboration with his wife Irene, he discovered artificially induced radioactivity early in 1934 for which they were awarded the Nobel Prize in Chemistry for 1935. The Joliot-Curies provided chemical evidence for transmutation ( the change of one element to another) with the change of aluminum into a previously unknown isotope (variety) of silicon. This led to the development of a new discipline - the production and study of radioisotopes (radioactive forms of elements), and their later investigations together with their collaborators unrolled the fission process as in the offered papers.

First editions of these importent papers in statistical mechanics. The so-called Koopman-von Neumann mechanics is a description of classical mechanics in terms of Hilbert space, introduced by Bernard Koopman (the paper offered) and John von Neumann in 1931 and 1932. Ergodicity was introduced by Boltzmann, but the modern theory started from the paper by Koopman, and has been a cornerstone of statistical mechanics since. The ergodic method has found impressive applications in the fields of statistical mechanics, number theory, probability theory, harmonic analysis, and combinatorics.As Koopman and von Neumann demonstrated, a Hilbert space of complex, square integrable wavefunctions can be defined in which classical mechanics can be formulated as an operatorial theory similar to quantum mechanics.Birkhoff's proof (in the third paper offered) of "the ergodic theorem was deemed as importent as his proof of Poincare's geometric theorem" (Landmarks Writing in Western Mathematics 1640-1940, p. 877).
