Dr Thandi Gumede
Dr Thandi Gumede graduated with a PhD in Polymer Science. She is from Intabazwe, Harrismith.
The Qwaqwa Campus of the University of the Free State was a hive of activity on 17 and 18 May 2019, when over 800 degrees, diplomas, and certificates were conferred on deserving achievers. These included six PhDs and 14 master’s degrees across the four faculties.

Congratulating the graduates on both days, was Africa’s youngest PhD and Industrial Psychology lecturer, Dr Musawenkosi Saurombe, and Prof Francis Petersen, Rector and Vice-Chancellor.

Be like heat

Dr Saurombe started her address by relating her school journey that saw her starting Grade 1 at age 5, thus later matriculating at the age of 15, having skipped Grades 3 and 10. She went on to emphasise the importance of building an honourable character.

“As a graduate, you will soon realise that your degree is useless if you do not have character,” she said to an attentive audience that continued to marvel at her remarkable school history. She encouraged graduates to be like heat that cannot be seen but can only be felt. “Noise can often be seen and heard, but it cannot be felt. However, while heat cannot always be seen, it is always felt. Be like heat and may your presence always be felt,” she said.

Do not focus on yourself

Prof Francis Petersen also encouraged graduates to look beyond their degrees by developing a set of critical values.
 
“For us as the university, this ceremony is not just about your degrees. It is about the values that you must live by,” he said. “As a graduate of the UFS, do not just believe what you are told. Ask questions and engage critically. Secondly, do not just focus on yourself. Remember that you are part of a community and it is your responsibility to make our world a better place for others. You need to be socially responsive to the needs of your community. Thirdly, remember that integrity plays a very important role. This will determine how others value you,” he said.

The two ceremonies also saw three current SRC members graduating. They are Lebohang Miya (BEd FET – Accounting and Business Studies), Duduzile Mhlongo (BA – Geography and isiZulu), and Mhlongo Sinemfundo (BA – Geography and isiZulu).

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.
