the making of experiment
 backstage
under construction

Not always do great scientists, not even Nobel laureates, make reliable predictions.... Richard Feynman, for instance, in the third volume of his celebrated Feynman Lectures on Physics, when dealing with the single electron interference experiment, maintained that the latter, due to unsurmountable technical difficulties, would forever remain a thought experiment (or Gedankenexperiment , in german).

In this section we look at the details of the experiment carried out by Merli Missiroli and Pozzi, examining the ingenious tricks which allowed the three to overcome the obstacles foreseen by R. Feynman and hence led to their successful accomplishment of the enterprise.

Snapshots from the 1976 movie "Electron interference".

2008: finally, after 30 odd years, we hear from the very voice of protagonist Giulio Pozzi the truth on just how the thin wire for the biprism was prepared. (shooting by F. Bisi - INFN Multimedia).

1976: a take of the "Electron Interference" movie where the assembling of the electrostatic biprism is shown. The accessory, utilized in the electron holography technique, is crucial in performing the electron interference experiment inside a transmission electron imicroscope.
