Berlin: Akademie der Wissenschaften, 1920. 1st Edition. First edition bound extract of a paper, The Propagation of Sound in Partially Dissociated Gases, “that is a bit off the beaten track for Einstein though its subject, fluids (liquids and gases) is one he dabbled in throughout his life” (Calaprice, Einstein Almanac). Weil 110; Boni 119.
Recognizing that while the “chemical equilibrium properties of gases were well understood, precise knowledge of the velocity of gas reactions was not sufficiently available,” Einstein sought to establish a method for the calculation of the rate of chemical reactions in a gas by means of observations on the propagation of sound (Mason, Physical Acoustics, 13). Item #1123
