La Computazione Quantistica
Get PDFInformazione Quantistica: sembra la formula stregonesca di un qualche personaggio poco affidabile. In realtà è un corpus di attività scientifiche che sta ricevendo sempre più attenzione, soprattutto da parte dei governi che aspirano ad ottenere la supremazia quantistica, come chiave di quella politica. Qui cercheremo di indicare le sue basi scientifiche e le sue possibili prospettive
Un universo oscuro
Get PDFIl Cosmo è molto più di quello che vediamo. Noi stessi, il nostro mondo, lo spazio nell'universo, è permeato da qualcosa che non conosciamo. Da un lato abbiamo una componente che sembra essere materia e formata da particelle che non conosciamo e che però costituiscono il cuore delle strutture nell'universo, la chiamiamo "materia oscura". Dall'altro lato una forma di energia, anch'essa di natura ignota e distribuita in modo uniforme ovunque, ma inosservata e con la particolarità di generare una potente forza antigravitazionale che costringe lo spazio nell'universo ad espandersi sempre più rapidamente, la chiamiamo "energia oscura". L'aggettivo oscura è la traduzione dall'inglese di dark che contiene più informazione di quanto non sia la sua traduzione italiana. Il significato di dark è legato non solo al fatto che queste due entità non si vedono, ma significa anche "non spiegate, misteriose", appunto, oscure. L'universo è composto per circa il 70% da energia oscura, il restante 30% da materia di cui circa il 25% è materia oscura e il 5% è materia ordinaria. Possiamo quantificare il tutto affermando che meno di 1/20 della densità totale del cosmo è il mondo che conosciamo, tutto il resto è un mistero fitto
A moderated mediation model of trust, self-construal and compliance with COVID-19 health regulations based on country differences
Get PDFEarlier studies examined the extent to which self-construal has an impact on individual compliance with COVID-19 regulations. However, existing literature has paid little significant attention to the behavioural outcome of self-construal across countries and cultures. The aim of this study was; 1) to determine whether interdependent self-construal predicts compliance with COVID-19 public health regulation, 2) to examine if the association was mediated by individual social trust, and 3) to test whether these associations were moderated by the respondents' country of residence (US x Indonesia). General adult respondents from the US (N=231) and Indonesia (N=440) voluntarily participated to complete a survey about trust in the government, interdependent self-construal orientation and compliance toward COVID-19 public health regulation. The mediation analysis using Hayes PROCESS macro demonstrated a significant role of social trust in mediating the association between interdependent self-construal and compliance. In addition, the moderation analysis of participants’ country differences (US x Indonesia) toward the link between interdependent self-construal and compliance showed a significant result. This current finding indicated that the effects of interdependent self-construal on compliance differed between the US and Indonesian groups. In contrast to those living in Indonesia, individuals residing in the US who showed greater access to inter-dependent self-construal demonstrated a greater tendency to adhere to the regulation when compared to those with a higher score in independent self-construal. Discussion and Implications of the study were discussed in the following paper
Making Alienation “accessible”. Towards a tripartite understanding of the concept, and its application to the British working-class
Get PDFThis article explores the concept of alienation. While acknowledging the valuable contributions of scholars in expanding its scope and application, the article argues for a more accessible and immediately intelligible understanding of the concept. By adopting an author-based thematic approach, the article examines the works of Hegel, Marx, and Alasdair MacIntyre to identify the key characteristics that define alienation. It highlights the interconnectedness of three central elements: the lack of agency, meaning, and the detachment of oneself from the community. These elements are synthesized into a comprehensive framework that can analyse the position of the working class in contemporary society. By doing so, it demonstrates the continued applicability of alienation as an analytical tool for comprehending and addressing issues in the modern world. By presenting a more accessible and streamlined conceptualisation, this article aims to encourage wider engagement with the concept of alienation and promote its use in public discourse
Angle between two complex lines
Get PDFThe chordal distance function on a complex projective space algebraically defines an angle between any two complex lines, which is known as the Hermitian angle. In this expository paper, we show that one can canonically construct a real line corresponding to each of these complex lines so that the real angle between these two real lines exactly agrees with the Hermitian angle between the complex lines. This way, the Hermitian angle is interpreted as a real angle, and some well known results pertaining Hermitian angles are proved using real geometry. As an example, we give a direct and elementary proof that the chordal distance function satisfies the triangle inequality
