Prof Francis Petersen, Rector and Vice-Chancellor of the University of Free State, South Africa, invites us to rethink our relationship with the world in a series of ‘Courageous Conversations’ on the theme of ‘The Global Citizen’. Prof Petersen argues that COVID-19 has been a powerful ‘disruptor’ – it was a stark reminder of the need to rethink our identity, of where we belong, our ‘normative’ view of citizenship – if we want to secure long-term survival of our civilisation and the environments that support it.

Global Citizen and the role of Digital Futures – Monday, 27 September - 13:30 SAST / 12:30 BST 

How we turn information into intelligence is the subject of SACC’s next ‘Courageous Conversation’ with University of the Free State Vice-Chancellor, Prof Francis Petersen, in his series debating ‘The Global Citizen’.  “I believe the world needs multi-disciplinary solutions to its global problems.  For this reason, I established the Interdisciplinary Centre for Digital Futures at the University of the Free State as part of my vision to infuse the natural and social sciences and the humanities with everything that digital brings to a multi-disciplinary approach in order to solve real-world problems through the power of big-data analysis,” says Prof Petersen.

Prof Philippe Burger, the UFS Pro-Vice-Chancellor for Poverty, Inequality, and Economic Development, together with Prof Katinka de Wet and Herkulaas Combrink, the interim co-directors of the Interdisciplinary Centre for Digital Futures, will join Prof Petersen to discuss the value that such an approach can bring to finding solutions to real-world problems. They will also share information on some of the exciting projects of international relevance that they are working on. Agriculture and food security, medicine, and attitudes to issues such as, for example, vaccination, education, governance, and ethics are key foci of the centre.

Join us to find out how big-data analysis and a multi-disciplinary approach can transform understanding and deliver solutions to some of the challenges we face as citizens of the world.

The Global Citizen Courageous Conversations series

In partnership with the South African Chamber of Commerce based in the United Kingdom, the Global Citizen Courageous Conversations series that was launched on 26 May 2021, brings together powerful voices from public life, intellectuals, public interest and business leaders, academics, naturalists, religious leaders, astrophysicists, economists, ecologists, and others.

If you missed our previous Global Citizen Courageous Conversations, you can watch the replay on YouTube, or visit the South African Chamber of Commerce website for the recordings.

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.
