Prof Daniel Green - Guest speaker at UICSJ webinar
Prof Daniel Green is the guest speaker at the UICSJ webinar.

Signs, symbolism, and statues at universities often recall colonial and apartheid legacies. In South Africa – since students at the University of Cape Town marched to topple a statue of Cecil John Rhodes – a so-called ‘Fallist Movement’ emerged that aims to decolonise universities. In 2020, catalysed by the death of George Floyd, the Black Lives Matter Movement has emerged, with a strong emphasis on removing symbols and practices that perpetuate segregationist legacies and harms of slavery, apartheid, and colonialism. Fallist and Black Lives Matter protests are against injustice and for dignity, equality, freedom, peace, and justice in society. As with other South African and global universities, the University of the Free State is a site of slow, complicated, and often conflict-ridden struggles for transformation. 

The Unit for Institutional Change and Social Justice (UICSJ) will be hosting a webinar with the theme (Re)moving, (Re)naming, (Re)forming, and (Re)presenting: Towards Dignity, Care, and Social Cohesion in Higher Education, on 24 November 2020.

This webinar will ask pluriversal questions with the aim of restoring dignity within new, dense notions of communities that are capable of the kinds of care that grant dignity and worth to all. In particular, this virtual conference will speak to experiences and struggles related to changing how spaces, symbols, artefacts and other oppressive accoutrements endure at universities, conveying meanings, narratives, and cultures that must be overcome. The webinar will (re)centre critical and creative voices. Local and international participants will present multiple dimensions on the struggles involving naming and renaming, as well as the removal, recontextualisation, or replacement of statues and memorabilia, within a broader effort towards social justice.  

What the webinar seeks to address

  1. How do we address signs, symbolism, and statues in public spaces that misrepresent or degrade an individual/group with a view to restoring (collective) dignity?
  2. How do we address signs, symbolism, and statues that memorialise/celebrate people or representations of history that are controversial?
  3. How do we deal with the strong emotive/affective aspects of history and heritage, culture, and the loss thereof, in a way that enhances dignity and justice?
  4. What are the best processes for reconstructing public spaces and who should be involved in broad-based consultations?

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.
