If the Yang-Mills theory is the answer, what is the
question?
Abstract. Yang-Mills theories play a central role in modern
physics, forming the basis for the Standard Model (SM) of elementary
particles and forces. The SM has proven to be an exceptionally successful
theory, representing our most sophisticated theoretical framework for
understanding the properties of matter and interactions at the fundamental
level. In technical terms, interactions in the Standard Model are described
by a Yang-Mills theory with the local SU(3)cxSU(2)LxU(1)Y
gauge symmetry. The objective of this article is to explain to
non-physicists, who wish to learn something about contemporary physics, what
this statement means. As the author is not a physicist, this text is intended
as an introduction to Yang-Mills theory for a non-expert audience. However,
given the sophistication of Yang-Mills theory, the paper assumes a fair bit
of mathematical background. It includes some technical details, although
these are largely presented in a superficial manner.
Bornological convergences
Abstract. We study a family of
convergences (actually pretopologies) in the
hyperspace of a metric space
that are generated by covers of the space. This family includes the Attouch-Wets, Fell, and
Hausdorff metric topologies as well as the lower
Vietoris topology.
The unified approach leads to new developments and puts into perspective some
classical results.

Artificial Intelligence: What Is It and What Can It
Do?
Summary. Artificial Intelligence (AI) is not just an
abstract field for experts. It is already having a pervasive impact on daily
life as a practical technology that influences our economic opportunities and
societal norms. AI is important for everyone because it is reshaping almost
every aspect of our lives, from the way we work and make decisions to how we
access services and participate in civic society. AI drives everything from personalised recommendations on streaming services to
critical decision-making in sectors like finance and healthcare. As AI
systems become increasingly integrated into our everyday tools and services,
it is important for individuals to understand the principles on which they are
based. This allows them to navigate the digital world, appreciate the
convenience that AI offers, and be sceptical of any
potential biases or hidden agendas that could affect their personal data or
the outcomes of decisions.
This essay examines the concept of artificial intelligence, its origins,
operational mechanisms, and capabilities.
It attempts to explain the key principles and algorithms, and their
real-world applications. The paper is primarily intended for individuals
interested in the technical foundations of AI. However, the author believes
that a basic understanding of these principles is necessary for anyone who
wants to grasp the technology's potential, limitations and associated risks.
Consequently, this text may also be of interest to readers with less of a
technical background.
