Ettore Majorana - Disappearance at Sea and Suggested Explanations

Disappearance At Sea and Suggested Explanations

Majorana disappeared in unknown circumstances during a boat trip from Palermo to Naples. Despite several investigations, his fate is still uncertain. His body has not been found. He had apparently withdrawn all of his money from his bank account, prior to making a trip to Palermo. He may have travelled to Palermo hoping to visit his friend Emilio Segrè, a professor at the university there, but Segrè was in California at that time and, as a Jew, was barred from returning to Italy under a 1938 law passed by Benito Mussolini's government. On March 25, 1938 Majorana wrote a note to Antonio Carrelli, Director of the Naples Physics Institute, asking to be remembered to his colleagues and saying that he had made an unavoidable decision and apologising for the inconvenience that his disappearance would cause. This was followed rapidly by a telegram cancelling his earlier plans. He apparently bought a ticket from Palermo to Naples and was never seen again.

Several possible explanations for his disappearance have been proposed, including:

  • Hypothesis of suicide, by his colleagues Amaldi, Segrè and others
  • Hypothesis of escape to Argentina, by Erasmo Recami and Carlo Artemi (who has developed a detailed hypothetical reconstruction of Majorana's possible escape and life in Argentina)
  • Hypothesis of escape to a monastery, by Sciascia
  • Hypothesis of kidnapping or killing, to avoid his participation in the construction of an atomic weapon, by Bella, Bartocci, and others
  • Hypothesis of escape to become a beggar ("omu cani" or "dog man" hypothesis), by Bascone.

Famous quotes containing the words sea, suggested and/or explanations:

    O you singers solitary, singing by yourself, projecting me,
    O solitary me listening, never more shall I cease perpetuating you
    Never more shall I escape, never more the reverberations,
    Never more the cries of unsatisfied love be absent from me,
    Never again leave me to be the peaceful child I was before what
    there in the night,
    By the sea under the yellow and sagging moon,
    The messenger there aroused, the fire, the sweet hell within,
    The unknown want, the destiny of me.
    Walt Whitman (1819–1892)

    It would be easy ... to regard the whole of world 3 as timeless, as Plato suggested of his world of Forms or Ideas.... I propose a different view—one which, I have found, is surprisingly fruitful. I regard world 3 as being essentially the product of the human mind.... More precisely, I regard the world 3 of problems, theories, and critical arguments as one of the results of the evolution of human language, and as acting back on this evolution.
    Karl Popper (1902–1994)

    Financiers are great mythomaniacs, their explanations and superstitions are those of primitive men; the world is a jungle to them. They perceive acutely that they are at the dawn of economic history.
    Christina Stead (1902–1983)
