From an early age, many have been taught that strangers are not only a danger to the individual, but to the communities too.

A StrangerKind (ASK), an organisation hosting unconventional conversations in communities on topics and responding to questions that many may not have the opportunity to ask, has partnered with the University of the Free State to host the talks that aims to promote curiosity, diversity, and social cohesion.

As part of the ASKcampus – a first to be hosted at any university in the country – participants will have an opportunity to talk to a stranger in a safe setting and ask any question that comes to mind, without any judgement.

Michelle Nöthling, Assistant Researcher in Kovsie Support Services, said: “The ASK event is an opportunity for participants to pick a topic from a list that sparks curiosity and book an available 45-minute time slot. During your session, you sit down to a one-on-one conversation with a stranger who will briefly introduce themselves and their topic. They will then share their personal life experience on that topic with you.”

The event, which will be launched at the Thakaneng Bridge, Bloemfontein Campus, on 28 July 2022, is open to both UFS staff and students.

“During the individual sessions, participants may ask the strangers anything about the chosen topic. We even encourage you to ask those questions that you might otherwise have been too shy, or felt were too ignorant, to ask. What is more, is that the strangers you will meet will be fellow UFS staff and students. But you will not know who your stranger is until you sit down with them,” said Michelle.

Individuals who want to know more about becoming a UFS stranger are encouraged to visit the organisation’s YouTube channel or register to attend training and become a ‘stranger’.

Be curious. Be brave. Talk to strangers.

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.
