La scomparsa di Majorana Pearing because he had precociously realized that nuclear fission would inevitably lead to the atomic bomb This book advances a different hypothesis Through a careful analysis of Majorana's article The Value of Statistical Laws in Physics and Social Sciences which shows how in uantum physics reality is dissolved into probability a. Would you like a beautifully made and elegantly tailored story about a brilliant physicist whose mysterious disappearance coincides with international controversy about uantum mechanics and the nature of science itself Yes Would you like it to embody some of the largest uestions about how we view governmental power and how we understand complex subjects through statistics Yes Would you like an Italian philosopher to wrap all of the above up for you in oh I don t know 60 pages or soNo wasted words No unfounded thoughts No dependence on canon Agamben you brilliant man This is a lesson in probability superimposition and governance it is about science and dice As the physicians such as Majorana have realized Any experiment performed on an atomic system exerts a finite perterbation on it that cannot be eliminated or reduced for reasons of principle The result of any measurement seems therefore to be concerned with the state the system is led to during the experiment rather than with the unknowable state of the system before being perturbedThis from an essay where the physicist describes the parallel between the natural and social sciences Of course many social scientists will agree too and have known this for a long time the presence of an experimenter changs the outcome of an experiment These bizarrely called social facts are assertions of power in a domain ruled by probability But this is about not just the experiment but also how the vision of experimentation to understand the world has changed we are not trying to understand the world any longer we scientists seek to understand the probability of something abstracted from a controlled situation in which their intervention has changed reality I ll let Agamben say it Majorana clearly saw the implications of a mechanics that renounced every non probabilistic conception of the real Science no longer tied to known reality but like the statistics of social sciences only intervenes in it in order to govern it For Agamben and here he is also following Simone Weil this entails that science has left behind its objective for so many years that was to understand the reality of the world Now science moves through statistical reason and it assumes a probabilistic model of the world And as soon as we assume that the real state of a system is in itself unknowable statistical models become essential and cannot but replace reality Governance follows the world departs from sight the pursuits of human activity become speculative and ungrounded and science so long the bastion of humanistic reason can no longer answer the simple uestion what is real

La scomparsa di Majorana Eighty years ago Ettore Majorana a brilliant student of Enrico Fermi disappeared under mysterious circumstances while going by ship from Palermo to Naples How is it possible that the most talented physicist of his generation vanished without leaving a trace It has long been speculated that Majorana decided to abandon physics disap. Life Imitating Science uantum physics forced the recognition of something that had always been the case but had been ignored by both scientists and philosophers of science Metrics are never a property of the event or thing being measured Or to put the matter generally mathematics is not analogous to what is the case in the worldThis unexpected and disconcerting conclusion is obvious in uantum physics because the probabilistic character of uantum events can only be analysed within an imaginary world of chance The mathematics of chance cannot be analogous to reality because the one who calculates probability relies on risk without actually taking a risk that is to say he leaves reality and at the same time transforms chance l hasard into a principle allowing him to decide on reality This means that probability is never punctually realized as such nor does it concern a single real event but it allows us to intervene in reality as considered from a special perspective in order to govern it This idea of governing reality by measuring it that is imposing an order on it that is not inherent was an insight formulated by the Italian physicist Ettore Majorana in the 1930 s He recognised it as a fundamental implication of Heisenberg s Uncertainty Principle and of the research results of Planck and Fermi among others If his insight was correct what had been considered scientific in the past was no longer possible to conceive as such All measurement not just measurement of the very small was an intervention in reality in order to command a response That response typically showed up as a position on a metric provided by the scientist The event or thing measured had no intrinsic properties but it became a property of the metric through the process of measurementReality does have a defence against such intrusive interference it disappears it refuses to respond That is the event or thing may leave its mark on the metric employed but its existential reality escapes further scientific scrutiny It is unclear whether reality is destroyed through measurement or simply evades discovery This is a central poetic mystery of uantum physics But it is also the reason psych tests can t identify incipient mass killers democratic elections are unpredictable and no one has ever seen dark matter Reality is beyond the reach of language and therefore measurementIt is also a central mystery of the fate of Ettore Majorana who after sending various cryptic messages to friends and family members in 1938 disappeared without a trace Whether he committed suicide or fled to an isolated monastic existence is an issue that can only be resolved probabilistically based on the available evidence But it is clear that Majorana succeeded in commanding his own immunity from further observation and therefore measurement Agamben s view is that Majorana for his own hidden reasons was demonstrating the reality of a uantum world by acting it out in his own life if uantum mechanics relies on the convention that reality must be eclipsed by probability then disappearance is the only way in which the real can peremptorily be affirmed as such and avoid the grasp of calculation Majorana turned his very person into the exemplary cipher of the status of the real in the probabilistic universe of contemporary physics and produced in this way an event that is at the same time absolutely real and absolutely improbable In short whatever reality is it is not to be found through science A rather profound point in such a brief philosophical anecdote and an even profound way to pursue one s life in science

La scomparsa di Majorana Nd in dialogue with Simone Weil's considerations on the topic Giorgio Agamben suggests that by disappearing into thin air Majorana turned his very person into an exemplary cipher of the status of the real in our probabilistic universe In so doing the physicist posed a uestion to science that is still awaiting an answer What is Rea. Che cos reale domanda che sempre pi acuisisce senso in un mondo che nel lavoro nelle relazioni nei bisogni si dematerializza costringendoci a nuove modalit di percezione uindi a diverse forme di necessit e desiderio codifica e comprensione che creino e stabilizzino la realt Ettore Majorana geniale ed inuieto fisico che avrebbe potuto competere con Fermi scompare la sera del 25 marzo del 1938 dopo essersi imbarcato a Napoli su un piroscafo diretto a Palermo Nessuno lo rivedr n ne avr notizie le ultime risalgono a due lettere contraddittorie dello stesso Majorana datate il giorno della sua scomparsa e uello successivo nella prima si accomiata lasciando presagire una volont di suicidio nella seconda annuncia il suo ritorno e la rinuncia all insegnamento universitario uesta indeterminatezza lo spunto da cui Agamben muove le sue riflessioni nello stesso campo di studi di Majorana la fisica che in uel particolare momento storico la fisica uantisticaDa Planck a Bohr da Heisenberg a Einstein da Schrodinger a Fermi e Oppenheimer a partire dai primi decenni del Novecento i maggiori fisici mondiali conuistano e si lasciano conuistare da una nuova teoria che affianca le leggi generali della fisica classica senza mai sostituirle la fisica degli atomi dei uanti degli stati discontinui dell energia dell influenza dell osservatore sul sistema osservato e dell impossibilit della conoscenza ovvero della misura dello stato di un sistema della capacit degli esperimenti di governare la materia La fisica uantistica opera una rivoluzione rispetto alle leggi deterministiche della fisica classica fondata sul concetto di probabilit prima dell osservazione sperimentale un sistema si trova contemporaneamente in tutte le posizioni ed solo al momento dell osservazione e della misura che ne occupa una secondo una distribuzione di probabilit Poich per sua natura la probabilit non si riferisce mai a un singolo evento reale ecco che nasce un mondo parallelo a uello reale uello delle probabilit che pu influenzare le scelte rispetto alla realt ovvero permette di intervenire sulla realt governandola Ecco uindi che nella fisica uantistica la realt si eclissa nella probabilit Su uesti presupposti si compiuto lo sviluppo scientifico dell ultimo secolo le cui scoperte e applicazioni stanno negli ultimi decenni imprimendo un accelerazione al mutamento delle tecniche e delle tecnologie e di conseguenza delle societ accelerazione che per il momento ci impedisce di fissare la realt in uno stato determinato Anzi la realt sembra sempre pi assumere essa stessa la forma di una distribuzione probabilistica che ancora non siamo in grado di calcolare Ed ui che Agamben chiude il cerchio la scomparsa di Majorana sarebbe avvenuta per la volont stessa di Majorana di confutare la teoria oggetto dei suoi studi come metodo di dimostrazione della sua validit e universalit La scomparsa risulta essere un evento assolutamente reale e al tempo stesso assolutamente improbabile non potendo essere misurata per effetto dell assenza dell oggetto da misurare in uesto caso il corpo dello scienziato Un modo geniale ed inuieto per riproporre la domanda cui la scienza non ha ancora saputo dare risposta che cos realeLa statistica non una scienza volta alla conoscenza sperimentale del reale piuttosto la scienza che permette di prendere decisioni in condizioni di incertezza
