First Edition, Offprint Issue. Sommerfeld’s theory of the freely vibrating piston diaphragm. “The problem had presumably arisen in the context of ‘questions of underwater noise,’ which Fritz Renner, commissioned by the [German] Navy’s Experimental Telecommunications Command (Nachrichtenmittel-Versuchskommando), had worked up before being requisitioned by Sommerfeld as his assistant. In this case, though, it was less the physics associated with the problem that made this an interesting case for Sommerfeld, than the mathematical treatment. In studying more closely the pertinent technical literature on acoustics, he found that a procedure for solving the boundary value problem in question which to him seemed particularly useful appeared to be unknown in that domain” (Eckert, Arnold Sommerfeld: Science, Life and Turbulent Times 1868-1951, p. 413). Sommerfeld presented this copy to theoretical physicist Gregor Wentzel, who made notable contributions to quantum mechanics; Wentzel had served for a time as Sommerfeld’s assistant.Book Id: 50955
