As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar as part of the Free State Literature Festival’s online initiative, VrySpraak-digitaal.

The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa. Some of the topics for 2021 include, among others, reimagining universities for student success; corruption; local elections, the state of business – particularly in the Free State.

In 2020, the webinar series saw the successful participation of leading experts engaging on COVID-19 and the crisis facing the country socially, economically, and politically. This year, in lieu of the Free State Arts Festival, the UFS will present the webinar virtually over a period of five months.

Fourth webinar presented on 24 August 2021
What South Africa will look like after the recent unrest in KwaZulu-Natal and Gauteng, is yet unknown. As the country is attempting to normalise while tallying the human, political, and economic cost of the riots – what we know for sure is that the events of the past few weeks have dispelled the impression of South Africa as exceptional, with a triumphant future. Moreover, the inconsistent response from government during and after the unrest laid bare the divisions within the ruling party. As South Africans are reeling from the aftermath of the looting, a lacklustre response from leaders with unreliable, conflicting messages has brought little comfort to those most in need.

What happens now? What will it take for South Africans to advance a cohesive vision to provide a sustainable future for the next generation?

Date: Tuesday, 24 August 2021
Topic: Is South Africa falling apart – where to from here?
Time: 12:30-14:00
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 20 August 2021

He currently serves on the boards of Swiss Re Africa Limited, Rand Merchant Bank Limited (RMB), the Automobile Association of South Africa, and SBV. Prof Mohale was the former Chief Executive Officer of Business Leadership South Africa (BLSA). In 2001, he received the President’s Award for his servanthood in South African industry, and in 2019 the Free Market Foundation’s Luminary Award. Prior to joining BLSA, Prof Mohale was the Chairman of Shell Downstream South Africa (Pty) Limited, and Vice-President of Shell Upstream.
Ms Nikiwe Bikitsha

Nikiwe Bikitsha is a former journalist who has been at the forefront of major national and international developments in a news and current affairs broadcasting career spanning twenty years. Nikiwe is a Fulbright Hubert H Humphrey Fellow – the Humphrey programme is a mid-career Fulbright exchange fellowship awarded to people who have demonstrated leadership. Nikiwe holds an MA in Journalism and Media Studies from the University of the Witwatersrand, and an MSc degree in African Studies from the University of Oxford. She serves as trustee on the board of the Nelson Mandela Foundation, is a member of the Deloitte Global Advisory Council and an independent non-executive director of Deloitte Africa. Despite leaving journalism, Nikiwe remains a keen observer of society.
Ms Qaanitah Hunter

Qaanitah Hunter is an award-winning political journalist and author. She is the political editor of News24 and author of Balance of Power: Ramaphosa and the future of South Africa. Qaanitah has won a number of awards for her work, including the Nat Nakasa award for brave and courageous journalism in 2019. She is currently a master’s student at the University of the Witwatersrand.  She has reported fearlessly on state capture, the Zuma years, and the political transition thereafter. Her constant probing and investigations have played a pivotal role in holding truth to power. Her writing on South African politics and investigations has featured prominently on many national media platforms, often setting the agenda in the country. Qaanitah is well-versed in issues of governance and her well-rounded and balanced political reporting has contributed to her astute analysis of news and current affairs. She has fought strongly against censorship and intimidation among journalists and has been a strong advocator for the freedom of the press. Qaanitah believes that the prospect of any democracy to persevere is pinned on how free the media is and its ability to hold those in power accountable.
Prof Anthony Turton

Prof Anthony Turton is an Affiliated Professor in the Centre for Environmental Management at the University of the Free State (UFS). He specialises in strategic planning, transboundary water resource management, policy and institutional issues, conflict resolution (mitigation), political risk assessment for large infrastructural projects, and research programme design. He is also the Director of Nanodyn Systems Pty Ltd. Prof Turton’s focus is on resources, more specifically the need to overcome water and energy constraints to our future economic growth and prosperity, both as a country and the entire SADC region. As an environmentally aware person, he believes that we are reaching the limits to our current developmental approaches and will be forced to make changes in the near future, whether we like it or not. By understanding and anticipating this, Prof Turton assists organisations in staying ahead of the game by isolating fundamental drivers at work and by identifying emerging opportunities.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
