Abstract | Einstein, a theoretical physicist, also contributed to practical realizations, such as the little machine, his "Maschinchen." The goal was to measure small electrical potentials. Although Einstein proposed it as "a new electrostatic method to measure small quantities of electricity", the method was not new. As far as we know, three original copies of the Maschinschen still exist. Only one of the instruments was used in research. Because the physical principles on which the instrument is based have not been explained clearly, we discuss these principles in more detail. Simulation of the charge amplification is performed and the equilibration time of the instrument is estimated. © 2006 American Association of Physics Teachers. |
