Introduction

In 1938, Italian physicist Ettore Majorana vanished after taking a sudden sea journey. At first it was feared that he'd ended his life, but the perplexing circumstances left the truth uncertain. In this week's episode of the Futility Closet podcast we'll review the facts of Majorana's disappearance, its meaning for physics, and a surprising modern postscript.

We'll also dither over pronunciation and puzzle over why it will take three days to catch a murderer.
