UFS - Thought-Leader Webinar

2024 UFS Thought-Leader Webinar Series

PRESENTS

a webinar titled

2024 Elections: Promises, Perils, and Delivery: What the Future Holds After 29 May 2024?


The University of the Free State (UFS) is pleased to present its first webinar for the year, titled 2024 Elections: Promises, Perils, and Delivery: What the Future Holds After 29 May 2024? – which is part of the 2024 Thought-Leader Webinar Series. As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the university will be presenting the webinar as part of the UFS Thought-Leader Series, which is in its sixth consecutive year.  The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa.

 

Webinar presented on 23 May 2024

On 29 May 2024, South Africans will go to the polls. This election is considered by South Africans as significant and much needed since the end of apartheid in 1994. South Africa is plagued by record power cuts, poor service delivery, and high levels of unemployment, with drastic effects on businesses and the local economy. Coinciding with the celebration of 30 years of freedom and democracy, this seventh democratic election is a turning point for South Africa to determine the desired future for all South Africans.

Date:   Thursday 23 May 2024

Time: 12:30-14:00

RSVP:  Click to view document HERE no later than 22 May 2024.

Some of the topics discussed by leading experts in 2023 included, among others, Threats to South Africa’s stability and security challenges; The need for a global and regional plan / approach to respond to the consequences of the Russia-Ukraine war; and Student protest action, politics, and higher education.

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.
