Dr Munyaradzi Mushonga is very optimistic about his appointment as the Global Academic Director of the Decolonial International Network.

Dr Munyaradzi Mushonga of the Centre for Gender and Africa Studies (CGAS) at the University of the Free State (UFS) has been appointed Global Academic Director of the Decolonial International Network (DIN). Dr Mushonga, who is a senior lecturer and programme director of CGAS’s Africa Studies programme, says his vision for DIN is “to work towards a new world civilisation that is opposed to the militarism and war, lawlessness and genocides of other civilisations.” 

Dr Mushonga, who is a leading voice and scholar on decolonialisation, will formally assume his role at DIN in 2023. 

The duality of new technology and scholarly work

Dr Mushonga says it is important for our minds to be decolonised, and he is therefore planning to establish a Centre for Decolonising The Mind (CDTM), which will use 21st-century technologies to achieve the ideal of decolonialisation. “Here pluriversal decolonial chapters and centres will be driven towards developing a decolonial history app,” he says. The aim is also to work towards a decolonial textbook on the history of Africa. 

He says it is commendable to employ technology to address decolonisation, but the real work to achieve the ideal of a decolonial mind lies in the scholarly work done by academics. At the CGAS the entire Africa Studies programme addresses decolonial theory and praxis through several approaches. “These are informed by our identity, which is anchored on two pillars, namely the interdisciplinary nature of all our engagements, as well as the exploration and critique of what it means to be ‘human’, but also in relation to the ‘non-human’ world.” He adds that the Centre’s teaching, supervision, and engagement with its students also challenges academics to think beyond the binaries of ‘coloniser’ and ‘colonised’, ‘white’ and ‘black’, and to reject all forms of fundamentalism. 

UFS’s commitment to decoloniality is a great asset 

Dr Mushonga's tenure at DIN will also reinforce the commitment to decolonial education made by the UFS, which has been noted by DIN. “I am convinced that DIN, the CGAS and the UFS can become the great vehicles to drive the decolonial agenda from the global South in general, and South Africa in particular,” he says. He says the commitment to the ideals of decolonisation displayed by UFS and the CGAS played a large part in his appointment to his new DIN role. 

The CGAS and the UFS will become key players in the DIN project, and Dr Mushonga hopes that more individuals and groups will come forward to join forces with DIN. “I hope this will enable DIN to push for new ethics in living.”

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.
