		Ettore Majorana, nato il 5 agosto 1905 e laureatosi in fisica nel 1928, fu tra i più promettenti allievi di Enrico Fermi.
		Ettore è l'ultimo di cinque fratelli, che si distingueranno tutti in qualche campo particolare, chi nella giurisprudenza, chi nell'amministrazione dello Stato, chi ancora in fisica.

	Ettore Majorana Summary
		Ettore Majorana (Catania, Sicily, 05 August 1906 – Tyrrhenian Sea, 27 March 1938 (presumed)) was an Italian theoretical physicist who began promising work on neutrino masses.
		In 1931, Majorana published the first paper describing the phenomenon of autoionization in atomic spectra, designated by him as "spontaneous ionization"; an independent paper in the same year, published by Arthur Shenstone of Princeton University, first used the term "auto-ionization", which has since become conventional, without the hyphen.
		Also in 1932, Majorana published his paper on a relativistic theory of particles with arbitrary intrinsic momentum, in which he developed and applied infinite dimensional representations of the Lorentz group, and gave a theoretical basis for the mass spectrum of elementary particles.

		Ettore Majorana was born a century ago (in August 1906) in Catania in an era when nuclear physics, still in its historical infancy, was gradually being recognised as a distinct science.
		Ettore's uncle, Quirino Majorana (1871-1957), was an experimental physicist at the University of Bologna.
		Ettore Majorana disappeared from a ship during a routine trip from Palermo to Naples in March 1938 and was presumed dead.

		Ettore Majorana (Catania, 5 agosto 1906) è un fisico italiano scomparso misteriosamente nel 1938.
		Majorana aveva continuato a frequentare l'Istituto di Roma e a lavorarvi saltuariamente, nel suo modo peculiare, finché nel 1933 era andato per qualche mese in Germania.
		Il 26 marzo Carrelli ricevette da Majorana un telegramma in cui gli diceva di non preoccuparsi di quanto scritto nella lettera che gli aveva precedentemente inviato.

	Ettore Majorana: genius and mystery - CERN Courier
		Ettore Majorana was born in Sicily in 1906.
		Majorana had explained to Fermi why the particle discovered by Joliot and Curie had to be as heavy as a proton, even while being electrically neutral.
		Majorana jotted down a new equation: for a chargeless particle like the neutrino, which is similar to the electron except for its lack of charge, only two components are needed to describe its movement in space-time - as if it uses two wheels (like a motorcycle).

	Majorana 2006 - Abstracts
		Majorana formulated his equation both for spin integer and half-integer spin obtaining as a result a theory with a mass spectrum spin dependent.
		In his article, Majorana considers quantum mechanics as an irreducible statistical theory because the theory is not able to describe the time evolution of a single particle or atom in a controlled environment at a deterministic level.
		Ettore Majorana, probably the most brilliant Italian theoretical physicist of the last century (as well-knowm, Enrico Fermi compared him to Galileo and Newton), disapeared misteriously from Naples in 1938, when he was 31 yeras old: and this year, 2006, we celebrate the centennial of his birth.

		Ettore aveva risolto a mano e in un giorno l'equazione che Fermi stava studiando con una rudimentale calcolatrice da settimane.
		Ettore partecipava ai seminari informali nello studio di Fermi, dove i ragazzi imparavano veramente a fare fisica e si diffondeva la nuova meccanica di Schroedinger, Heisenberg e Dirac.
		Majorana poteva addirittura rifiutare di pubblicare un'intera teoria, nonostante i consigli di Fermi che spingeva sempre a sorvolare sui dettagli matematici e sulla completezza, che sarebbe venuta certamente in seguito.

	Ettore Majorana
		Ettore Majorana era nato il 5 agosto del 1905 in via Etnea 251.
		Ettore era un genio della fisica, precocissimo, eccentrico, misantropo, ombroso, indolente, dagli occhi cupi grandi e nerissimi.
		Nel campo delle particelle elementari, Majorana formulò una teoria che ipotizzava l'esistenza di particelle dotate di spin arbitrario, individuate sperimentalmente solo molti anni più tardi da P. Dirac, e W. Pauli fra il 1936 ed il 1939 (Teoria relativistica di particelle con momento intrinseco arbitrario, 1932).

	ETTORE MAJORANA
		Ettore crebbe quindi in un ambiente familiare culturalmente elevato, formato da professionisti ben inseriti in campo universitario e della politica (uno zio era professore di fisica all’Università di Bologna, mentre il nonno era stato un politico esperto di economia e finanza).
		Majorana si mostrò subito interessato al nuovo campo di indagine anche perché aveva già trattato quell’argomento nella sua tesi di laurea.
		Venuto in possesso di questa nuova scoperta Majorana abbozza una teoria in cui immagina che protoni e neutroni siano gli unici costituenti dei nuclei atomici e Fermi lo invita a pubblicare i risultati di questa intuizione ma egli si rifiuta, adducendo a giustificazione il fatto che l’opera era ancora incompleta.

		En cela, Majorana n'aurait fait que s'appliquer à lui-même les principes de sa spécialité, la mécanique quantique, pour laquelle le monde (des particules) est régi par des lois de probabilité et non par des certitudes.
		Majorana réapparaît brièvement sur la scène de la physique théorique en signant son papier le plus brillant, où il soutient que le neutrino (particule électriquement neutre, de masse infime) est à la fois matière et antimatière.
		Qu'il l'ait voulu ou non, Ettore Majorana a disparu en laissant flotter derrière lui plein de mondes possibles.

		Besonders interessant allerdings werde der Fall, wenn man bedenke, dass Majorana scheinbar der Kernspaltung (und damit der Atombombe) auf der Spur war, und aufgrund der Tragweite seiner Entdeckung beschlossen habe, sich aus der Forschung zurückzuziehen.
		Denn Majorana, wie Sciascia Sizilianer, war nicht etwa ein italienischer Meisterkoch, sondern ein Physiker, der wirklich gelebt hat.
		Majorana hat noch vor Heisenberg bahnbrechende Entdeckungen in der Kerntheorie gemacht, aber nicht veröffentlicht, erzählt unsere Rezensentin.

	Ettore Majorana - Di Renzo Editore
		Ettore Majorana (1906-1938) passed through theoretical physics like a meteor.
		The widening of theoretical physics’ spheres has favoured an increasing awareness of the deep connection between symmetries and interactions, and a renewed conception of theoretical physics and mathematics relation.
		Which thing allowed the new generation of theorists to get out new topics from Majorana work and to approach theoretical physics according to what we can define as the Majorana style.

		"Wärst du einige Wochen später gekommen, hättest du mich nicht mehr angetroffen", soll Majorana damals gesagt haben.

	Electronic Journal of Theoretical Physics
		In 1932 Ettore Majorana proposed an infinite-component relativistic wave equation for particles of arbitrary integer and half-integer spin.
		Thanks to the Majorana representation of spinors as 2s-tuples of points on the Riemann sphere, classes of anticoherent states are easy to find; the development of such examples also leads us into some curious geometry involving the perfect solids.
		In context of a transformation between Majorana and Dirac wavefunctions, it suffices to solve the related interactive Dirac problem and then apply the transformation of variables on the Dirac wavefunction in order to obtain the Majorana wavefunction of the given Majorana equation.

		Majorana was mathematically extremely gifted, and was very young when he joined Enrico Fermi's team in Rome as one of the "Via Panisperna boys", who took their name from the street address of their laboratory.
		Some argue for this latter hypothesis, conjecturing that after having envisioned the destructive power of atomic energy, Majorana did not want to contribute to its deployment in a fascist state.
