La scomparsa di Majorana READ & DOWNLOAD ✓ PDF, DOC, TXT or eBook Ý Giorgio Agamben Giorgio Agamben Ý 0 CHARACTERS 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
