Volta’s Battery in Einstein and Infeld’s "The Evolution of Physics"

In their famos book "The Evolution of Physics" Albert Einstein and Leopold Infeld gave paramount importance to Volta's battery in the development of physics. For the functioning of a "Voltaic cell", they assumed the modern electrochemical theory and this circumstance is taken as the starting point to present Volta's different conception of a "Voltaic cell" and to stress the historical framework in which notions such as that of the "Voltaic cell" must be placed to be meaningful.
