The meaning of race, culture and sexism in Africa takes a different tone than it does in the West. The West has always tried to create an identity for Africa, but the real question remains: “What does it mean to be an African?’ 

“My aim with this book was to see how discourse is formed and what it means when you say the word ‘African’, which is meaningless. You have to look back to understand how that was created,” said Prof Charles Ngwena.

Prof Ngwena’s new book, asks the critical question,‘What is Africanness?’ Fully titled, What is Africanness? Contesting nativism in race, culture and sexualities is a timely contribution to contemporary South African debates on issues of decolonisation, race, ethnicity, nation building and belonging.

Identity formation a crucial element

“The book speaks directly to African cultural heritage and deconstructs a Western-imposed and homogenising framework for understanding Africanness,” said Dr Nadine Lake from the Centre for Gender and Africa Studies (CGAS) at the University of the Free State (UFS).

Prof Ngwena foregrounds the importance of intersectionality when approaching issues of race, culture and sexuality and writes: “Genericness is ineluctably homogenising. It can serve to obscure heterogeneities among women, pre-empting the need to explore the implications of differences among women in feminist theory and praxis.

“Identity is being and becoming. It is always changing. What young people think of identity is not the same way their grandparents thought about it,” said Prof Ngwena. He added that his contribution through this book was to underlay identity formation.

The book, published by Pretoria University Law Press (PULP), was launched in a joint venture by CGAS, the Centre for Human Rights at the University of Pretoria on Tuesday 11 September 2018 at the UFS.

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.
