The group’s question puts psychanalysis into a necessary question about the historical origins of its epistemologic fundamentals. At the hearing of the 20th century two major intellectual revolutions will fundamentally change our view on the nature of the reality and, upstream, on the subject itself...

International audience The characterisation and the precise measurements of the atmospheric concentration of pollutants are essential to improve the understanding and the modelling of urban air pollution processes. The QualAir platform at the Université Pierre et Marie Curie (UPMC) is an experimenta...

This thesis relates to the study of orthogonal polytency families and their links with exactly resolvable models. It is divided into two parts. In the first, there are four new families of orthogonal polytency using borderline processes applied to families belonging to the Askey and Bannai-Ito schem...

In the last 20 years, the concept of quantum intrication has become an important part of the study of N body quantum systems encountered, for example, in condensed material theory. Intrication entropia is a measure of intrication between two parts forming a system in a pure quantum state. The study...

In the background of any question about the concept of completeness of a theoretical system, of any kind, we know that some of the results of logic and metamathematics are held, and the names of Gödel and Tarski, for example, must be borne in mind. Although completeness in physics is of a very diffe...

'pbNovie daily has been upset for about 30 years by a technological revolution based on objects such as transistor or laser. This would hardly have been possible without the contribution of quantum physics. In a book that is intended to be open to any cultured and not necessarily scientific audience...

summary Conventional cryptography is based on mathematical concepts whose security depends on the complexity of calculating the inverse function. This type of encryption is at the expense of computers’ computing power and the discovery of an algorithm that allows the inverses of certain mathematical...

The mysteries of the quantum world: Do you know enough about the laws that govern our world? Do you not want to understand everything that is happening in your smartphone or how to explain the colour of the brakes by the prism of quantum physics? It will be necessary to deconstruct your intuition to...

why did Michel Houellebecq never really become a science-fiction writer? At least part of the response is a strategic reflection, with Houellebecq trying to escape what he believes to be the deadlock in gender literature, in which science-fiction, moreover, seems to be in decline. But it is clear th...

Quantum physics has been taught again in the class of Terminale Scientists since 2012 in France. The quantum object has properties that are incompatible with those of conventional physics and the fiction of the Schrödinger cat is paradoxical. Many literary and science-fiction stories showcase this f...

The importance of non-self-adjoint operators in modern physics increases every day as they start to play more prominent role in Quantum mechanics. However, the significance of their examination is much more recent than the interest in the examination of their selfadjoint counterparts. Thus, since ma...

The category of “natural” has a bad reputation when it comes to gender and sexuality: it is often used to centralise and valorise “good” behaviours and reject “bad gender” on the monster and counter-nature side, but if the “Nature” itself was deviating? And if the matter itself was made of people wh...

In this work, we consider, first, mathematical models of the weak decay of the vector bosons W into leptons. The free quantum field Hamiltonian is perturbed by an interaction term from the standard model of particle physics. After the introduction of high energy and spatial cut-offs, the total quant...

International audience Sulfur concentrations have been measured in 28 melt inclusions (MIs) in plagioclase, clinopyroxene, and olivine crystals extracted from tephra produced during the explosive eruption of Grímsvötn in May 2011. The results are compared to sulfur concentrations in the groundmass g...

The idea of determinism, proposed to extend and generalise physical causality, adding in particular the consideration of the initial conditions, was therefore the ideal reference and considered to be insuperable in any scientific knowledge. However, this ideal was to be overtaken in several directio...

It is common that nowadays there is a curious juxtaposition around the world between, on the one hand, highly developed scientific knowledge in an environment dominated by technical achievements linked to that knowledge (of which they are largely applied) and, on the other hand, beliefs and practice...

The role of the Quantum Mechanical Observer has given rise to a few interpretations highlighting the observer’s awareness to the extent. These are marginal interpretations, but are among the most widely known by the general public. In classical physics, knowledge of the material world is assumed to...

Can neurosciences lead to a new adolescence metapsychology? The article by N. Georgieff led us to question the concepts of completeness and integration, the first of which was developed by G. Devereux. He borrowed questions about the nature of the theories caused by the development of quantum and re...

The time seems to be irreversible a priori and man hardly accepts the collapse of the possibilities of the future in the fixity of the past. Science has taken up this powerful issue from the 1930s on the basis of Albert Einstein’s generalised relativity theory. But long before the appearance of quan...

International audience The reconstruction mechanisms built by the human auditory system during sound reconstruction are still a matter of debate. The purpose of this study is to propose a mathematical model of sound reconstruction based on the functional architecture of the auditory cortex (A1). The...

writes in collaboration with Paul Musset After recalling the relationship between the energy and time scales of the universe according to the cosmological model, and the various phases of the vital universe, which correspond to all stages of unification of the theory of basic particles and their fie...

Post-exotism offers a destabilising reading experience. The self-referential fictional universe created by Antoine Volodine keeps the boundaries between people, but also between real and dream, truth and invention, in an undefined way. This world, which already disrupts readers’ expectations, is in...
