Leipzig: Johann Ambrosius Barth, 1911. 1st Edition. HANDSOMELY BOUND FIRST EDITION OF 5 PAPERS BY ALBERT EINSTEIN. Note that the ORIGINAL FRONT WRAPS ARE BOUND IN. The front wraps of the five issues of Annalen der Physik that are bound here have been retained and are bound at the rear of the work. Four are Weil papers, numbers 38, 39, 40, and 41 respectively. Number 39 is denoted with an asterisk, meaning it is considered a “principal work”.
Weil number 39 is “Eine Beziehung zwischen dem elastischen Verhalten der spezifischen Wärme bei festen Körpern mit einatomigen Molekül” or A Relationship between Elastic Behavior and Specific Heat in Solids with a Monatomic Molecule. In it, Einstein comments on an important 1910 paper by the Australian physicist William Sutherland that appeared in Phil Mag. “Sutherland made the important remark that the infrared eigenfrequencies of solid bodies have their origin possibly in the elastic vibrations of these bodies. Einstein, impressed by this remark, adds that electrically charged ions are the sources of optical vibrations, whereas elastic vibrations are caused by the mutual motion of the entire molecule. Hence he prefers to test the hypothesis of Sutherland by solid bodies which are composed of monatomic molecules”(Lanczos and Calaprice 31). Item #813
