The newly appointed editor of the University of the Free State(UFS) journal for humanities Prof Henning Melber had vowed to give the publication a deeper insight on critical issues ranging from decolonisation of knowledge to knowledge production.

In his first editorial opinion as the new Editor of the Acta Academica journal, Prof Melber said the publication has the declared intention to apply a critical social theory perspective.

“Dedicated to scholarship in the humanities, Acta Academica will henceforth be published annually with a minimum of two issues, plus an optional additional issues per year,” he said. 

Former Editor Professor Lis Lange, previously Vice-Rector: Academic at the University of the Free State (UFS), has moved to the University of Cape Town as Deputy Vice-Chancellor for Teaching and Learning.

The journal publishes scholarly articles that examine society, culture and politics from a critical social theory perspective and it is also interested on scholarly work that examines how the humanities in the 21st century are responding to the double imperative of theorising the world and changing it.

Analysis on Africa encouraged for Acta Academica

As a journal promoting humanist values and ethics, Prof Melber stated that he would like to see Acta Academica publishing scholarly analysis and think pieces that engage with such challenges in a critical (and gendered) theoretical perspective. 

“We welcome in particular contributions that link to current themes and processes on the African continent and especially to Southern Africa, without abandoning the global context and the shared perspectives of committed
scholarship elsewhere,” he said.

Decolonisation of knowledge

“We will promote an emphasis on contributions in the fields of post-colonial, development, cultural, gender, international and African Studies aiming to support current efforts towards a decolonisation of knowledge and knowledge production. 
He said the journal will combine an international post-colonial discourse inspired by critical theory and other relevant schools of thought applied to and/or generated in a local and regional (African) context. 

“We also welcome efforts to contribute to the decolonisation of knowledge, which still to a large extent is anchored in the global asymmetries. We cannot pretend these asymmetric power relations and inherited structures do not exist.  “Nor will we be able to avoid their reproduction completely. But we can promote ownership of authors over their intellectual product and will disseminate the work as widely as possible,” he said.

New Editor calls for diversification of knowledge


In another efforts to decolonise, Prof Melber said they would also make special efforts to empower aspiring African scholars. As part of this endeavour, the UFS’s Centre for Gender and Africa Studies has for several years, been the partner institution of Africa Spectrum for the annual Young African Scholars Award

“We will try to create similar opportunities, encouraging early career scholars to submit articles. In addition, we would like to expand the character of contributions, by further diversification of forms of knowledge transmission through debate articles, reports, comments, review essays and other thought-provoking interventions. We hope to receive your support, as potential authors or as readers who contribute to or benefit from Acta Academica’s efforts to further a stimulating debate,” he said

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
