As part of the initiatives lined up for College Week, the student leaders of West College at the University of the Free State (UFS) hosted a dialogue that primarily focused on discussing social justice as a value of Vision 130. The dialogue was held at Outeniqua Residence on 3 September 2024 and was well attended by students within West College.
According to Oratile Reina, West College Prime, “the motivation for the dialogue was to prepare newly elected leaders and our college community to align their efforts with Vision 130 – a vision that aims to create a more inclusive, equitable, and socially just environment on campus”. As such, she highlights that the dialogue was an opportunity for leaders to discuss practical strategies for implementing these values in their respective spaces, and to encourage those in West College to become better citizens inside and outside the university.
A conversation on social justice
The dialogue was facilitated by Geraldine Lengau, Senior Officer in the Unit for Institutional Change and Social Justice at the UFS. Lengau touched on several aspects pertaining to the topic of discussion. Firstly, she allowed the audience to give their definition of social justice, especially as students within the institution. In addition, she went on to talk to the audience about sexual assault in the context of social justice. In this instance, Lengau gauged whether the students knew which processes to follow in the event of a sexual assault incident, and whether they were acquainted with the UFS Sexual Harassment, Sexual Misconduct, and Sexual Violence Policy. Furthermore, the audience was given the opportunity to outline what social justice looks like to them in the spaces they occupy, including in their respective faculties, the sports they play, and the leadership structures they form part of. “I was encouraged to see that students take their right to a socially just university in very high regard, and that they were willing to break it down from what Vision 130 proposes, in order to align it with their common understanding,” said Lengau.
As the dialogue concluded, the audience signed a pledge committing to uphold the values of Vision 130. According to Reina, “The pledge represents a promise to take concrete steps towards fostering an inclusive and equitable campus culture. By signing the pledge, the leaders are not only agreeing to embody these principles in their leadership roles but are also holding themselves accountable to their peers and the broader university community.”

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
