Takudzwa Nyamunda.

Takudzwa Nyamunda is the proud new representative of the University of the Free State (UFS) for the 2020 Commonwealth Future Student Leadership programme. Nominated at a recent workshop themed ‘Reimagining Peace’, organised by the Association of Commonwealth Universities in collaboration with the British Council and the Durban University of Technology, Takudzwa demonstrated exceptional leadership, coupled with his experience of issues related to the UFS student committee, which provided the perfect foundation for his selection. 

“From a personal point of view, this was one of the most enriching experiences I have ever had, both in terms of the relationships established and the world knowledge gained. I am personally grateful for the opportunity to attend and would support any further initiative of this nature. I think the essence of this workshop was to encourage the young leaders present – all of whom were active citizens in their communities in one way or another – to continue fighting the good fight. The core message from the panellists was that it is all worth it in the end, and that even in the face of adversity and discouragement, we should keep fighting for the work we believe in,” says Takudzwa. 

Participants from 13 nations, including activists and thought leaders on non-violence affiliated with the International Centre of Nonviolence, the Gandhi Development Trust, and the Commonwealth Countering Violent Extremism Unit, contributed to the workshop. Over the course of three days, participants were divided into five groups and worked together on projects linked to three main themes – gender-based violence, global warming, and inequality.

The selection committee was convened by the Vice-Rector: Research and Internationalisation, Prof Corli Witthuhn, and facilitated by the Office for International Affairs. Currently in the final year of his Master of Industrial Psychology degree, Takudzwa’s wealth or experience includes being the founder and first president of the International Students Association (2016), and holder of the International Student portfolio as Student Representative Council (SRC) member (2017), coupled with being co-founder and first vice-chairperson of the South African Board for People Practices (SABPP): UFS Chapter and Vice-president of the SABPP National Youth Council (2019).

“I will continue to do what I have been doing for the past five years at the UFS, which is to make a difference in my sphere of influence”, says Takudzwa.

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.
