Majorana

Portrait illustration for a AAAS Science article about the evasive Ettore Majorana (who disappeared without a trace in 1938) and his eponymous quasiparticle:

The Quantum Phantom – "A ghostly quasiparticle rooted in a century-old Italian mystery could unlock quantum computing’s potential—if only it could be pinned down."

P.S., from the article:

And 3 years ago, the researchers flew to UC Berkeley to visit the archive of Emilio Segrè, whose friendship with Majorana soured in the years before his disappearance. The researchers came across a folder that, per Segrè’s instructions, cannot be opened until the year 2057.

Excuse me?? I suppose I have to stick around until at least 2057 because I need to know wtf is in that folder.

Ettore Majorana: il genio della Fisica svanito nel nulla

[scienza-magia]

A velocità tachionica super-luminale

Non è proibito correre più della luce. I tachioni, ipotetiche particelle super-luminali, rientrano senza difficoltà in una nuova teoria. Non contraddicono la relatività di Einstein perché si salva il postulato della costanza della velocità della luce nel vuoto anche per eventuali osservatori “tachionici”. Un lavoro pubblicato venerdì 30 dicembre sulla autorevole rivista scientifica “Classical and Quantum Gravity” da ricercatori delle università di Varsavia e di Singapore presenta una “estensione della teoria spaziale della relatività” che va oltre il modello tradizionale a tre dimensioni spaziali più una dimensione temporale. Nel nuovo modello le particelle possono muoversi più velocemente della luce senza violare le leggi fondamentali della fisica. Su ipotetiche particelle superluminali, chiamate tachioni (dal greco takùs, veloce) i fisici lavorano da più settant’anni. In particolare se ne occupò Erasmo Recami (1939-2021, nella foto in alto), professore di fisica Università dell’Insubria e di Campinas, (Brasile), che fu anche il biografo ufficiale di Ettore Majorana. Nessun esperimento ha mai fatto sospettare l’effettiva esistenza dei tachioni ma non mancano interessanti lavori teorici che non escludono l’esistenza di un universo superluminale. Nella stessa relatività classica i tachioni sono ammessi a condizione che non possano varcare il confine tra velocità sub-luminali e super-luminali. Come una volta disse con una battuta maliziosa Tullio Regge, “Tachioni si nasce, non si diventa”. Secondo il lavoro appena pubblicato, supponendo che esistano particelle superluminali, ciò non significa che l’universo sia “indeterminato” dal fatto che le particelle inizino a muoversi simultaneamente lungo molte traiettorie, secondo il principio della sovrapposizione quantistica. L’esistenza di tali particelle richiede la creazione di una nuova definizione di velocità e cinematica, che salvi “il postulato di Einstein della costanza della velocità della luce nel vuoto anche per gli osservatori superluminali“, sostiene uno degli autori, Andrej Dragan. Il coautore e direttore dello studio, Krzysztof Turzyński, ha però fatto notare che è molto difficile trovare una tale particella: riuscirci non rivoluzionerebbe la fisica ma sarebbe pur sempre una impresa da premio Nobel.

anyway with SCOTUS apparently giving The Religionists a get out of civil rights free card i’m reviving the cult my old IRC group created

knowledge of the divine condemns your soul to torment. the only thing worse than knowledge is belief, the only thing worse than belief is proselytism, the only thing worse than proselytism is prophecy.

no knowledge of the divine can be recorded in permanent form (that would constitute prophecy). allusions and roundabout examples are permissible (but on thin fucking ice) so long as their meaning is not apparent to those who do not already know what they mean

anyone with excessive knowledge of the divine immediately dissolves into quark-gluon plasma with a distinct odor of piss and bacon (as happened to our founder the Trulyneutralpope and Mendaxiarch Ludentis II in a Corsican storm drain in 1982), but having any knowledge of the divine is sufficient for damnation upon your natural death and on Thursdays

we do not recognise a state of sin beyond knowledge of the divine. however there are three particular states of spiritual peril - being dreadfully serious, being on thin fucking ice, and being in polite company. none of these can have formal definitions (that would be dreadfully serious).

agreement on doctrine is sufficient - but not necessary - to constitute polite company, and thus a great spiritual risk to be avoided

to disagree on doctrine is to claim greater knowledge of the divine, and thus a greater state of spiritual danger. correcting someone spreads this knowledge and endangers them as well - proselytism.

the appropriate response to a doctrinal dispute is thus to accept your opponent’s argument unreservedly - while also preventing them from accepting yours

any three people with knowledge of the divine are considered quorate on temporal matters, so long as they are not dreadfully serious, on thin fucking ice, or in polite company.

the name of the divine is known, but can only be written as {}, and I cannot record how it is said - but adhering rigorously to this rule would be dreadfully serious, so i will step onto thin fucking ice and say it can reasonably be estimated by certain noises from the 1995 SNES video game Super Mario World 2: Yoshi’s Island, several harsh triangle waves, and a wilhelm scream. per the Convlex of 2009, this description itself does not constitute knowledge of the divine as it does not indicate the method to assemble these parts into {}

whereforth as the author of this document is known to possess knowledge of the divine as a participant of the canonical Convlices, and has ensured that any such knowledge has been excluded, whereforth as the author has no knowledge of any Convlex having occurred in a period of no less than ten years, nor knowledge or contact of any other participants of the Convlices in the same period, whereforth as all ordinals of a Convlex are presumed to have experienced the Dissolution if they have not emerged in a period of no less than five years, whereforth as the author remains physically able to write and smells neither piss nor bacon, whereforth as the author has renounced any claim to the seat of Pope and Antipope, the author as sole surviving ordinal of the Convlices may stand witless to proclaim this document utter nonsense and of no spiritual significance, may the divine fuck off and leave us in peace

Music and Aromatherapy

There are several articles on the use of music therapy in addition to aromatherapy and the positive effects they have on anxiety. In Son's (2019) study, 107 sophomore students preparing for a test at the nursing college at Sungshin Women’s University, Seoul, Republic of Korea, were enrolled to compare and assess the effects of single intervention modalities and combined intervention.

Origanum majorana (sweet marjoram) and Citrus sinensis (orange) essential oils were chosen for their stress relieving properties at a ratio of 1:1. A lamp was used to diffuse three drops for 20 minutes to reach peak levels in the body while participants listened to Beethoven’s Moonlight Sonata .

According to Son (2019), the combination of aromatherapy and music therapy resulted in a significant decrease in test anxiety, state anxiety, and stress. The subjects also performed better in fundamental nursing skills.

Here is a useful guideline for music intervention for relaxation: (Lindquist et al., 2014, p. 114)

Ascertain that patient has adequate hearing.

Ascertain patient’s like/dislike for music.

Assess music preferences and previous experience with music for relaxation.

Provide a choice of relaxing selections; assist with CD/MP3/tablet selections as needed.

Determine agreed-on goals for music intervention with patient.

Complete all nursing care prior to intervention; allow for a minimum of 20 minutes of uninterrupted listening time.

Gather equipment (CD or MP3 player, tablet device, CDs, headphones, fresh batteries) and ensure all are in good working order.

Test volume and comfort of volume level with patient prior to intervention.

Assist patient to a comfortable position as needed; ensure call-light is within easy reach and assist patient with equipment as needed.

Enhance environment as needed (e.g., draw blinds, close door, and turn off lights).

Post a “Do Not Disturb” sign to minimize unnecessary interruptions.

Encourage and provide patient with opportunities to practice relaxation with music.

Document patient responses to music intervention.

Discuss feelings of patient after using music intervention. Identify whether patient encountered any challenges or problems with the equipment.

Revise intervention plan and goal(s) as needed.

LA MACCHINA DI MAJORANA

LA MACCHINA DI MAJORANA

di Mariano De Pardi Sulla vicenda dello scienziato Ettore Majorana, sono state fatte molte illazioni, ma la sua improvvisa scomparsa nel nulla nel 1938, rimane a tutt’oggi avvolta da un inquietante mistero. Qualche anno fa dall’emittente radiofonica Gamma5, il dottor Alfredo Ravelli (autore di libri dedicati a Majorana e in possesso di alcune sue lettere inedite) raccontò la storia…

Plant of the Day

Tuesday 22 October 2024

The tender perennial sub-shrub Origanum majorana (sweet marjoram) is often grown as an annual or biennial. The masses of aromatic, edible leaves are ideal for edging a path. The white flowers are popular with pollinators. This herb needs a well-drained soil in a sheltered, sunny position.

Physicists uncover behavior in quantum superconductors that provides a new level of control

A new study has uncovered important behavior in the flow of electric current through quantum superconductors, potentially advancing the development of future technologies like quantum computing. In a paper accepted for publication in Physical Review Letters, the research focuses on Floquet Majorana fermions and their role in a phenomenon called the Josephson effect, which could enable more precise control of quantum-driven computer systems. The study is co-authored by Babak Seradjeh, Professor of Physics within the College of Arts and Sciences at Indiana University Bloomington, with theoretical physicists Rekha Kumari and Arijit Kundu of the Indian Institute of Technology Kanpur. It is available on the arXiv preprint server.
