Academic freedom and democracy. University in danger?

The notion of "academic freedom" is often evoked in public debates, but is it really known in its singularity? Where does it come from? What is its history? What decisive role does it play in our democracies and the defense of the university's role as a counter-power? To what extent is it threatened today, particularly by the reforms announced?This morning of reflection, open to all, will explore these questions from a variety of perspectives. Historians, philosophers and jurists will shed light on the subject. Institutional leaders will share their concrete experience and their analysis of the threats that reforms could pose to this essential principle.An organization of the Philosophy Department, the History Department, the ESPHIN Institute in collaboration with the Centre d'Action Laïque Namur.The speakers- Anne-Emmanuelle Bourgaux, Professor of Constitutional Law at the University of Mons- Nicolas Offenstadt, Professor of History at the University of Paris 1 Panthéon-Sorbonne- Quentin Landenne, Qualified Researcher at the FRS-FNRS at the UCLouvain Saint-Louis Brussels, scientific leader of the ERC BildungLearning project- Susanna Zellini, Research Fellow at the FRS-FNRS at UCLouvain Saint-Louis Brussels- Annick Castiaux, Rector of UNamur- Edouard Delruelle, Professor of political philosophy at ULiège; Chargé de mission by the Rectrice of ULiège on "ULiège facing global conflicts".PracticalitiesThéâtre Jardin Passion 39, rue Marie Henriette - 5000 Namur.Free admission - Welcome from 9amAn organization of the Departments of Philosophy and History of the University of Namur and the ESPHIN Institute in collaboration with the Centre d'Action Laïque Namur with the support of the ERC BildungLearning project.

First MG-ERC conference brings together the world's inorganic chemistry elite

In early September, the University of Namur hosted the first Main-Group Elements Reactivity Conference (MG-ERC). Over 100 researchers from 12 countries and 32 institutions gathered around Professor Guillaume Berionni. An event hailed as "one of the best chemistry conferences" by its prestigious guests.

Public defense of doctoral thesis in physical sciences - Jean-Pierre Fréché

SummaryAt a time when a stream of research was striving to reformulate quantum mechanics by abolishing operators and substituting functions, Wigner and Szilard proposed in 1932 a quasi-probability distribution defined on phase space thanks to wave functions. They did not explain its genesis.The first part of our thesis proposes a genesis of this quasi-distribution, based on the natural conditions it must fulfill. It briefly examines a pathology it suffers from: exhibiting negative values in certain subdomains of the phase space (hence the "quasi"), a pathology that does no harm to the calculation of mean values. She then shows how, if we take spin into account, with wave functions giving way to spinners, we are led, thanks to the calculation of mean values of observables, to a generalization of this quasi-distribution in the form of a Hermitian matrix. This approach is extended to the Wigner cross transform, i.e. to weak values.An important theorem, which has been the subject of a publication, is proved in the second part of our thesis. Using harmonic analysis, this result expresses weak values in terms of an integral over a Lie group acting on the Hilbert space under consideration. We give two particular examples: SU(2) and SO(3). The case of a quotient group is briefly discussed.In a third section, we recall the well-known link between Clifford algebras and two important equations of quantum physics: the Klein-Gordon and Dirac equations, and its generalization to Riemannian spacetimes.Finally, in a fourth section we introduce spin groups, and use the spin group Spin(3,2) in the context of the Wigner cross transform discussed in the first section.JuryProf. André FÜZFA (UNamur), PresidentProf. Yves CAUDANO (UNamur), SecretaryDr. Thomas DURT (Institut Fresnel and Ecole Centrale Marseille, Marseille, France)Prof. Romain MURENZI (Worcester Polytecnic Institute)Prof. Dominique LAMBERT (UNamur)Prof. Bertrand HESPEL (UNamur)Prof. André HARDY (UNamur)

Biodiversity of American rivers analyzed over 30 years

A team of American researchers, with the help of Frédérik De Laender, professor in the Department of Biology at UNamur, has just published in the prestigious journal Nature. Their study describes how changing stream temperatures and human introductions of fish can alter river biodiversity in the USA.

A prestigious publication for an international microbiology research team

The team of professor Xavier De Bolle has just published an article in the prestigious EMBO Journal published by Springer Nature.  His discovery? A lipid transport channel through the cell membrane of Brucella, the bacteria responsible for Brucellosis in cattle. This finding could be used to generate attenuated strains of the bacteria; a process used in vaccine manufacturing.

The role of women in the Resistance: a memory to be reclaimed

On April 8, the Histoire, Sons et Images research center (HiSI, a member of the Institut Patrimoines, Transmissions et Héritages - PaTHs) organized, in collaboration with the "Coalition 8 mai" association, a colloquium on the theme of the relationship between women and the extreme right. Bénédicte Rochet and Axel Tixhon, professors in the History Department, explored this theme from the angle of women active in the Resistance during the 40-45 war. Their approach is fully in line with the research center's vision, which studies audio and/or visual documents as historical sources, but also history as a way of understanding the present.

From video games to artificial intelligence, a stopover in Japan

Japan is almost 10,000 kilometers from Belgium, a country that fascinates, not least for its rich culture full of contrasts. Researchers at UNamur maintain close ties with several Japanese institutions, particularly in the fields of computer science, mathematics and video games. Let's take a look at some of these collaborations..
