In 1937, just one year before suddenly disappearing under mysterious circumstances, a brilliant italian physicist named Ettore Majorana predicted the existence of a very peculiar particle. Having the exciting property of being its own antiparticle (that is it simultaneosly behaves as matter and anti-matter) the elusive “Majorana particle” has been finally observed by a group of scientists at Princeton University \cite{Nadj_Perge_2014}. To achieve the important result they used a two-story-tall microscope to observe the end of a superconducting wire.
