# Ettore Majorana and his heritage seventy years later

@article{Esposito2008EttoreMA, title={Ettore Majorana and his heritage seventy years later}, author={Salvatore Esposito}, journal={Annalen der Physik}, year={2008}, volume={17} }

The physicists working in several areas of research know quite well the name of Ettore Majorana, since it is currently associated to fundamental concepts like Majorana neutrinos in particle physics and cosmology or Majorana fermions in condensed matter physics. But, probably, very few is known about other substantial contributions of that ingenious scholar, and even less about his personal background. For non specialists, instead, the name of Ettore Majorana is usually intimately related to the…
